Homemade snowmobile on wheels with their own hands. Snowmobile with your own hands: Making Tips

Those who love often ride fishing in winter, often face the problem of passability. After all, it is not always even on an SUV directly to drive up to the bank of the river and even more so for the place of fishing itself. Exit from such a situation will serve a caterpillar snowmobile. However, the price of such equipment in stores is sometimes not available, and therefore the need arises in the manufacture of such a device with their own hands. In today's article, we will look at how it is done on the caterpillars and that for this you need to have.

Caterpillar

First of all, it should be started from the most complex element of the construction of a snowmobile - caterpillars. Along with the engine, it is the main motor element of the whole technique. In order to do it, first need to make up the drawings of self-made snowmobiles on the caterpillars (approximately as in our second photo).

So you will know the exact sequence of work performed and will not forget about any small detail. And now about how to make a caterpillar in practice. To do this, we need to take a plastic tube (about 40 millimeters diameter) and 2 strips The number of pieces of stripes depends on how long your caterpillar is. Working with these details, or rather, their processing is easily produced on circular or (grinder). At the same time, it is necessary to cut the part on one wall at a time. It is necessary to ensure the accuracy of the work performed. How to connect a transport tape with halves of a cropped pipe? To do this, we will need two at the same time the diameter of their thread should be about 6 millimeters. If you combine this value of the elements with the manufactured structure, the step between the output of the output will be 93 millimeters.

With the "baiting" parts of the pipes with cut-off side, it is necessary to endure the distance between them. If the offset will be 3 or more than millimeters, this will lead to the inconsistent work of the teeth of the drive gear and the tape itself, which is why sliplocks will begin in the snowmobile. And this is already leading to the loss of manageability. This discrepancy can lead to the fact that the tape can simply slip from the rinks.

It is important to observe the dimension of the caterpillar. What is long it will be directly depends on the engine power on which the homemade snowmobile will work. On the caterpillars you need to calculate the nominal pressure of the whole technique on its plane. Thus, the curb weight of the snowmobile relative to the roadbed should be no more than 0.4 kg / cm 2.

How to produce tape drilling?

Homemade snowmobiles on a caterpillar go are quite normally working on ribbons drilled by the usual drill. However, that the device worked as long as possible, you need to drag the drill to work in advance. Pre-acquire a tool designed to process wooden surfaces. In no case do not use the metal drills.

The remaining parts of the chassis

With the rest of the aggregates, the case will be easier. For example, such nodes as axis and rubber wheels, "Buranian" leading stars and protected bearings can be purchased in any specialized store. By the way, the wheels are better to purchase inflatable. This technique will be softer on the go. The axis can be taken from a simple garden trolley (two-axis). If necessary, you can cut or, on the contrary, expand it to suitable values \u200b\u200bof technology. If you do not have the ability to purchase a leading shaft in the store, you can try to make it on the lathe. With the independent manufacture of the shaft, pay attention to the fact that in its size it is well tapped bearings.

Homemade Snowmobile on Caterpillars: Rama

We will perform the main carrying function and hold all the details, including the engine, in the same whole. By the way, you can use the power plant from the motorcycle along with the gearbox. But back to the frame. It we will make it made from the steel section with a diameter of 25x25 millimeters. At the same time, it is necessary to weld it in such a way that there are two longitudinal and three crossbakes. The presence of these parts on the frame will significantly strengthen its design.

Complete work

Finally, how to install on the homemade snowmobile on the caterpillars in the process of assembling a snowmobile here you need to make two swivel sleeves. This will be your steering mechanism. How it's done? To the front beam you need to weld a watering clutch with an internal thread by 1/3 inches and screw the nozzles with external threads in them. Nozzles already have ski racks and welded tushki for the steering thrust. By the way, you can use skis from the ordinary children's car "Argamak". But before that, pre-prepare them for the installation: Give the corners of the fastening of the rotary rack and produce the metal subsidence. This will significantly improve the maneuverability and quality of high speed snowmobile.

In our reviews, we have repeatedly affected the topic of assembling motorcycles and quad bikes with their own hands, and we did not pay attention to vehicles for movement in winter. We decided that you can no longer be bypass this topic, so today we will tell you how you can make a snowmobile with your own hands. Surely, it seems to you that a simple person who does not have experience in this area is such a challenge. But we are in a hurry to dissuade you - in this review we will try to tell the most clearly as possible how to collect snowmobile yourself, and that you will need. If you have long dreamed of having a homemade snowmobile in my garage, then it's time to begin to fulfill your dream into reality.

Why makes sense to assemble a snowmobile with his own hands?

Snowmobile is the best vehicle that you can use off-road in winter. If you are one of the lovers of winter fishing or hunting, and just a person who loves an active vacation, then such a vehicle as a snowmobile will be the best option for resting in winter. Recently, the motorcycle equipment market, which includes, and representatives of winter transport occurs a huge increase in prices. Because of this, buying a new snowmobile today is comparable with the purchase of a middle class car, which will certainly be on his pocket.

Outputs from the situation not so much, as I would like, so every wishes to acquire a snowmobile solves the problem with one of two ways. The first option is to buy a supported snowmobile, which was already in operation for several years. It is clear that this technique is no longer new, but the price allows you to save. In principle, buying a snowmobile from the hands is a good option. The most important thing is to choose the right model and well check the snowmobile for the presence of breakdowns.

Much more interesting, and as a rule, even more economical, there will be a snowmobile assembly with your own hands. In this case, you are not only saving big money, but also have all the opportunities for the snowmobile assembly especially for yourself. Make a snowmobile personally on the basis of some other vehicle - more than a real task. So why not try your hand and not collect homemade snowmobile, which will delight you every new trip?

What can make a snowmobile from?

At the first stages of the development of a self-made snowmobile, you need to decide on the choice, the so-called donor, that is, a vehicle on the basis of which the process of snowmobile construction will occur. There are not many options here, but they are quite enough to choose the most suitable for you. Basically, homemade snowmobiles are built on the basis of the following power units:

• Motorcycle
• Chainsaw
• Motobl

You can choose from this list the most suitable option to you. The only thing to remember is the power of a snowmobile, which will be at the exit. It is quite logical to assume that a snowmobile, made on the basis of even the simplest motorcycle, will be much faster than a snowmobile with the engine from chainsaws. Also more powerful chainsaws will be a motor-block, but the motorcycle still remains the best option, if we take into account the power of the vehicle. In our review we will analyze the construction of a motorcycle and a motor-block. So how to make a snowmobile with your own hands?

Motorcycle Snowmobile

To make a snowmobile with your own hands, using some kind of motorcycle we will need a welding machine and a drill, without which it is easy to do. As the basis of the future snowmate, we advise you to take Soviet motorcycles, for example, - Ural, Dnipro, Izh Jupiter or Izh Planet. It is these motorcycles that can be purchased sufficiently cheaply, and the power reserve of their engine is enough to travel to the most complex slopes without any problems.

Let's start with the front of the future snowmobile. The first thing you need to do is put a ski to the place. In our case, it will be only one, in order not to complicate and not weighing the design. After the wheel was removed, it is necessary to buy or make a skiing itself for a snowmobile, and with the help of a welding machine to weld it to the motorcycle fork as it is shown in the photo.

Now that the necessary work has been done with the front part of the snowmobile, you can proar. Everything will be more complicated here, but it is not so difficult to understand, as it seems at first glance. To begin with, it is necessary to lengthen the motorcycle frame, relying on the drawings, found by you on the Internet. Then the rear axle is installed, consisting of a tracked drum and tubular shaft. Optimal sizes for the caterpillar - 2200 × 300 mm with a thickness of 10 mm.

Motoblock Snowmobile

Snowmobile with their own hands on the basis of a motorcycle, is the most difficult version. If you don't care about the speed of the future snowmobile, then you can stay on a snowmobile on the basis of a motoblock. However, in this case, you need to make a snowmobile frame yourself. If you paint the whole process in stages, then you can sum up a few points:

• Making a snowmobile frame in the form of a rectangle made of metal pipes
• It is made independently or purchased in the store chair for the driver, then mounted on the finished frame
• Instead of wheels, two caterpillars are installed, made independently or purchased on the motorcycle engineering market
• On the frame of the future vehicle, skis for a snowmobile, which can be made independently of metal sheets are mounted.

Snowmobile from the motoblock Although inferior in the capacity of the same vehicle made from the motorcycle, but not as critical. But the big plus of this option is to build a snowmobile is simplicity and a short build time.

conclusions

In this review, we tried to answer the question as accurately as possible how to make a snowmobile with their own hands. The charm of the homemade snowmobile is that you can save a large amount of money and build a snowmobile that fully satisfies your needs.

Once people see snowmobile prices in the store, then ask a question how to make a snowmobile snowmobile yourself, how expensive is it expensive? How starts the manufacture of homemade - a snowmobile snowmobile? Initially, it is necessary to determine which power the engine is used. We used the engine of the motoblock in 6 horsepower. Usually, four-stroke engines with forced air or water cooling are installed on the motoblocks.

Motoblock can also be used reverse gearbox, centrifugal clutch, steering and fuel tank. Next, you need to consider the snowmobile propulsion. The tracked drive is installed on most of them.

Best Homemade - Motoblock Snowmobile

In the manufacture of a self-made snowmobile, caterpillars from other snowpots are used for it, or homemade, collected from undergraduated materials. After selecting the caterpillar, it is necessary to determine which type of suspension to use. It is necessary to choose from two main species: suspension on rollers and sewing suspension.

Each of them has both advantages and disadvantages. After that it is important to decide which snowmobile will be a layout. Usually, there are two steering skiing in front of the snowmobile and behind the tracked block.

The engine can be installed both from behind and in front of the snowmobile.

How to make a snowmobile snowmobile yourself

This snowmobile can be done in a few weekends at the cottage in the garage. At first glance, his design looks very simple. If you compare its permeability in the wet or loose snow, it will not give way to many industrial snowmates.

Creating a snowmobile proceeded from the principle: the less weight and more the size of the caterpillar, the higher its permeability of deep and loose snow. Therefore, the design will be the easiest.

How to make a homemade snowmobile from a motor-block on caterpillars

Four wheels are installed inside the caterpillar. When the movement occurs, they roll along the conveyor belt, with fixed plants. The caterpillar drive is carried out by a chain from the motor, special leading asterisks, through the slave shaft. They were removed from Buran.

The engine is taken from the usual motor-block, the power of which is 6 hp Quickly on it will not be attended. Soft suspension skiing and caterpillars was removed, because the snowmobile is designed for riding in a loose snow. This design was simplified and reduced snowmobile mass.

Making Cateries for Snowmobile

Consider the process of making the caterpillar. The plastic plumbing pipe is 40 mm, cuts a long 470 mm. Of these, billets will be made for soils. After that, each of them is crucified along the equal parts with a circular saw.

The soils are attached to the furniture bolts to the conveyor belt. When the caterpillar is manufactured, it is extremely important to maintain the same distance between the soils. Otherwise, the "incision" on the progress of the lead sprocket will occur, as a result of which the caterpillar will slip and slides from the rinks.

To drill holes in the conveyor belt for fastening bolts, conductor was made. For drilling holes, a tree drill was used, having a special sharpening.

This conductor allows you to drill six holes at the same time in the conveyor ribbon to attach three caterpillar primer. Leading asterisks were also purchased (2 pcs), inflatable rubber wheel (4 pieces), closed bearings №205 (2 pcs).

Tokar made a support for bearings and the leading shaft of the caterpillars. Rama snowmobile is made independently. For this purpose, square pipes 25x25 mm are used. Hinged axis of rotation of the steering wheel and skis are in the same plane and on the same line, so the continuous steering traction was used without ball lugs.

Pretty easily made ski rotation bushings. Pipe clutch, the internal thread of which is 3/4 inches, is boiled onto the front transverse beam. There are screwed nozzles with outdoor threads. They welded the thai skis rack and steering thrust. On skis are installed corners, which serve as an attachment to the rotting rack of the snowmobile. A metal line is made from below to better control snowmobile while driving on the rolled snow or an imaging.

Chain tension is regulated by the engine offset

Snowmobile control occurs quite simple. To increase the engine speed, the gase handle is used, which is located on the steering wheel. This includes an automatic centrifugal clutch, as a result of which the snowmobile begins to move. Since the engine power is small, then the snowmobile speed is 10-15 km / h. Therefore, the brakes are not provided. To stay, you need to reset the engine speed.

Caterpillars are made by any width. Choose what is more convenient to do: a narrow, but long caterpillar, or wide, but short. It is important to remember that a big caterpillar will load the engine more and complicate the snowmobile control. If the caterpillar makes a small one, then the car may fall into deep snow.

Snowmobile weight with all parts turned 76 kg. It includes: steering wheel and engine (25 kg), skis (5 kg), wheels with axes (9 kg), presenter shaft (7 kg), caterpillar (9 kg), seat with racks (6 kg).

You can reduce the weight of some details. For this size of a snowmobile with a caterpillar, the weight indicator is quite satisfactory.

Homemade Motoblock Snowmobile Video

In the conditions of the harsh Russian winter it would be nice to have a snowmobile. Previously, such a car was a luxury, and it was possible to buy it only abroad. Today, this vehicle can be found in almost any motorcycle. Snowmobile can be purchased simply for entertainment (for riding on winter fishing and hunting), sometimes without it can not do at work (rescuers, foresters, geodesists). The cost of a snowmobile depends on the manufacturer, modifications, power and other factors. The simplest model can cost about 100,000 rubles, and the price of a more advanced snowmobile comes to 1,000,000 rubles. Of course, if this technique is necessary for work, it is not worth saving, because the life of people may depend on the reliability of the snowmobile, especially if it is exploited by rescuers. But for entertainment, you can collect this miracle machine and at home.

Homemade snowmobile, will be able to build anyone a little bit of teaching in the technique. Before starting to make a snowmobile, you need to understand what advantages you will get from it.
Pluses of self-assembly:

• Cost. For some it can act the most important plus. The price of a homemade snowmobile will be cheaper at times than if you purchase it in the store.
• Characteristics. Making a snow unit, you yourself control the whole process, choose a configuration, power and appearance.
• Reliability. Collecting the device yourself, you will use the best components and details.

You can use a high-quality car with your own hands not only in the city, it is quite safe to travel beyond the limits of settlements, ski bases and travel off-road.

Where to begin?

It is best to start working on the assembly of the device with your own hands with the drawings. To create a drawing, not unnecessary engineering skills will be. However, if you did not succeed, then you should use the Internet and print the finished scheme. The World Wide Web has the opportunity to find drawings of snowmobiles of different modifications, from the simplest and cheap options to complex, construct that are only experimental mechanics. The drawings are in general access, printing which you can easily build a dream car.
Studying drawings, pay attention to the mass of the unit than it will be easier, the higher it will be its permeability. Snowmobile with ease will maneuver in loose and deep snow. However, not only the mass of the finished product affects the permeability, the support area of \u200b\u200bthe caterpillar is equally important.

What does a snowmobile consist of?

Any snowmobiles consist of basic details that will not be treated regardless of the modification of the device, such as:

1. Frame. You can use the frame from the old motorcycle or scooter, if there is no such, then you can cook it to order. Tokar will easily cope with such a task.
2. Engine. You can use a motor from a motoblock, although it is worth saying that when it is power, the resulting product is better called a children's snowmobile, to overclock it until a decent speed will not work. There is an alternative to use a motor from a motorcycle or scooter. The selection of the engine depends on the mass of the snowmobile.
3. Caterpillars The most important and at the same time complex snowmobile detail.
4. Drive unit. Connects the engine and caterpillar. For the drive, the chain from the motorcycle is perfect.
5. Steering wheel. It is necessary to repel from personal preferences and convenience, but most often it also takes from a scooter or motorcycle.
6. Skiing. It uses a ready-made version, if any, or can be skiing from plywood. It is better to give preference to sheets of plywood with a thickness of at least 3 mm.
7. Fuel tank. For this part, select the plastic or metal container. The capacity of 15 liters is quite sufficient to overcome long distances. It does not take much space.
8. Seat. It is best to make to order, since the homemade snowmobile will be operated in harsh conditions, one should give preference to durable, wear-resistant materials. Do not forget about convenience, you must feel comfortable on it.

Is it possible to make caterpillars yourself?

This is the most difficult element for self-making. Machine caterpillars play a decisive role in which speed will develop the unit, and what will be a hitch with an ice coating. Caterpillar made qualitatively made by handicrafts. Most often for caterpillars use tires from the car. First you need to free the tires from the sides, leaving only a flexible track. Now you need to make soils. To do this, use a plastic pipe with a diameter of 4 cm. It is necessary to cut it into parts of 50 cm long, the resulting billets cut into place even along. These details are attached to the tires bolts. It is important to observe the same interval of fitting of soils, otherwise the caterpillar will jump off the rink. It will be optimally attached to a distance of 5 cm from each other.
A similar method makes caterpillars. For their manufacture, you need to use the conveyor tape, which should be cut off by making the length optimal for the self-made unit. It is important to correctly hide the cropped tape correctly. For this, its ends are superimposed on each other by 5 cm and fixed with bolts.
Alternatively, for the manufacture of caterpillars, you can use the wedge belts. They are bonded by the soils, forming a caterpillar with ready-made mests under the gear.
Making caterpillars with their own hands need to take into account such a nuance: the greater the area of \u200b\u200bthe caterpillar, the better the device will pass along the snowdrifts, but the management will be worse. In stores, finished products are most often represented in three versions, with standard tracks, wide tracks and superworthy.
To simplify the task, instead of independent production, you can buy caterpillars in the store. Thus, you will get the opportunity to purchase caterpillars suitable under the terrain and movement conditions.

Features assembly

The finished frame, welded by the personally or borrowed from other techniques, should be equipped with a steering wheel with welding. The engine is installed strictly according to the drawing. It is best that it is located as close as possible to the carburetor. On the finished design you need to establish caterpillars that were made in advance.
When the main work is done, you can start connecting the tank, gas cables and brakes, the installation of the seat.

The easiest way to make a snowmobile

Take the fiberboard and modify it into a snowmobile - this is probably the easiest way to create an aggregate for movement in the snow. It can be used completely, you can take only some details.
If the motoblock is fully used, then it is necessary to welcome the frame with the rear axle and modify the working shaft to the drive, which should transmit rotating movements from the engine to the track.
If you do not fully use a motor block, then only the engine and the steering plug should be taken from it. You will need to install caterpillars on the bottom of the fork.
In this case, it is also necessary to take into account that the power of the motoblock is designed for the weight and pressure of wheels that are less than caterpillars. In order to avoid excessive waste of gasoline and depreciation of parts, snowmobile wheels should be low pressure.
Mini homemade snowmobile is easy to manage. By the way, if the homemade snowmobile turned out not very powerful and develops speed up to 15 km / h, it is not necessary to equip it with its brakes. To stop a self-made snowmobile, it is enough to simply reduce the turnover, and he will stop himself.
Going to work seriously and having studied all available information, for sure you will be proud of your aggregate collected yourself!

With the beginning of winter, especially snowy, problems associated with movement appear. Few people know that the snowmobile can be constructed from the subwoofers as an alternative vehicle in winter conditions.

At the same time, there is no need for serious costs. Moreover, if there is a large number of snow on the car you will not leave, but the snowmobile will allow moving in such conditions without any problems.

The assembly of any design begins with the development of drawings. They can accommodate all the necessary aggregates, after which it is possible to proceed to the practical implementation of the idea. Therefore, at this stage, it is necessary to determine the chainsaw of which brand is suitable for the realization of the conceived.

Selection of chainsaws

In the outlets you can meet several chainsaw models. The most popular of them, it is a chainsaw "Friendship", chainsaw "Ural" and chainsaw "CHTIL". Before choosing, you should think well, comparing their specifications.

Chainsaw "Friendship"

This is the easiest chainsaw that can be used as a snowmobile engine. As a result, it turns out an elementary design without anything superfluous.

The only drawback is a big weight with relatively low power. In addition, there are no parts for fastening safety housings. In addition, this design is outdated in all indicators.

Specifications:

• Power - 1 kW;
• Weight - 12 kg;
• Engine (two-stroke);
• Tire length - 45 cm;
• Fuel (gasoline).

Chainsaw "Ural"

This is a specialized model that has greater reliability, power and less weight, with respect to power. This is an environmentally friendly unit capable of working in extreme conditions.

If it is decided to use the "Ural" chainsaw, then this is a good choice. Its technical characteristics are fully compliant, declared.

Specifications.

• Power - 3.68 kW;
• Weight - 11.7 kg;
• Engine (gasoline two-stroke);
• Overall dimensions - 46x88x46 cm;

Chainsaw "CHTIL"

It is also suitable for creating a snowmobile with your own hands. This is an environmentally friendly apparatus, absolutely harmless to humans. The main advantage of chainsaws is low weight and silent in work, compared to the chainsaw "Ural", and even more so, if compared with the chainsaw "Friendship".

Making a snowmobile snowmobile diagram with their own hands

Snowmobile assembly schemes from the "Ural" chainsaw: 1 - steering wheel; 2 - fuel tank (from chainsaw "Friendship"; 3 - power unit (from the "Ural chainsaw"); 4 - a sleeve of a steering wheel skiing (pipe with a diameter of 30-2 pieces); 5 - steering ski (2 pcs.); 6 - Drive gear wheel track (Capron, Sheet S15, 2 pcs.); 7 - Caterpillar (from a snowmobile "Buran", shortened); 8 - frame; 9 - reference roller (from potato sorting, 18 pcs.); 10 - Troops Backlit backrests (pipe ½); 11 - Tensioner caterpillar (2 pcs.); 12 - Tension gear wheel caterpillar (Capron, Sheet S15, 2 pcs.); 13 - Bearing No. 80204 in the case (4 pcs.); 14 - Dog-trunk of the bottom-plywood S4, board board S20); 15 - seat (plywood cover S4, foam, leatherette); 16 - 1st chain transfer stage; 17 - 2nd Chain Transmission Stage; 18 - backrest seat (pipe ½ inches); 19 - driven asterisk of the 1st chain transmission (a large stroke of the track, intermediate shaft); z \u003d 38; 20 - the leading asterisk of the 2nd chain transmission stage (small stroke of the chaimmer), Z10; 21 - driven asterisk of the 2nd degree of chain transmission (drive asterisk of the drive shaft of the caterpillars), Z18; 22 is the leading asterisk of the 1st stage of the chain transmission (asterisk of the output shaft of the gearbox), Z12; 23 - Rotary fist lever; 24 - steering thrust (2 pcs.); 25 - steering shaft with a compartment; 26 - front axle beam (pipe diameter 30); 27 - drive shaft of the caterpillars; 28 - Tensioning axis of the caterpillar.

Without the creation of the scheme and drawing, it is unlikely to connect together the basic structures units, such as:

• Engine;
• Transmission;
• Skis and caterpillars.

To simplify the design process, you should take the caterpillar from the Burand Wide. If a children's option is constructed, then there will be a skis.

Stands

Steering Ski: 1 - poloz (Capron, S20 sheet, from a children's snow science); 2 - spring (normally stretched, from the rear shock absorber of moped); 3 - Supplement springs; 4 - cut (duralumin corner 20x20); 5 - Spring cover (corner 35x35); 6 - fastening the spring to the lid (bolt M8 with a washer); 7 - reference lever (pipe 30x30); 8 - spring fastening springs - forks to the lever of the ski (steel, sheet S2); 9 - spring fastening lever to ski (steel, sheet S2); 10 - axes (bolt M8, 2 pcs.); 11 - Rotary fist stand (bicycle steering rack with crown and part of the fork); 12 - steering tower (steel, sheet S4); 13 - mounting steering tower (type M16); 14 - Fastening the springs of spring and springs of the lever to the ski (bolt M5 with a secret head, 7 pcs.); 15 - lever sleeve (steel pipe with a diameter of 30 mm); 16 - Slip bearing (Kapron sleeve, 2 pcs.); 17 - Stand bushing (steel pipe with a diameter of 30 mm). On the top view of the detail 11, 12, 13 of the swivel fist are not conditionally shown.

Snowmobile racks can be made of 3x3 cm. They are connected with each other with steel jumpers. As a result, there is a relatively not large portal. To create a pad, you need to take a sheet, 2 mm thick and combine it with the portal and the middle of the right side of the vehicle elements. This venue will serve as a place for fastening a gearbox and chain transmission shaft.

On parts of the rear portal and the middle of the snowmobile should be formalized not a great place for the design of the seating.

The front of the frame and traverse of the front bridge are connected by the beam. As a beam, there is a conventional water pipe, with a diameter of 1.5 cm. At the end of this pipe, the steering ski bushings are attached with the help of welding, and the center is mounted. The rack will serve as a support for the motor subframe.

Special attention should be paid to the points of attaching racks. For greater reliability, the attachment points are amplified by steel brazers, 2 mm thick. This approach will strengthen the vehicle and make it more reliable and durable.

Caterpillar

Snowmobile frame with caterpillar block: 1 - rear side of the spar (steel sheet S2, with flames, 2 pcs.); 2 - tensioning device (4 pcs.); 3 - rear portal (corner 30x30); 4 - middle side of the spar (corner 50x63, 2 pcs.); 5 - Bracket-plug Installation of the axis of support rollers (steel sheet S2, 10 pcs.); 6 - average portal (30x30 corner); 7 is a platform for fastening the gearbox of a power unit and an intermediate shaft-mud (steel sheet S2); 8 - Kosinki (steel sheet S2, 4 pcs.); 9 - front portal (30x30 corner); 10 - anterior component of the spar (steel sheet S2 with flames); 11 - axis of tension gears; 12 - Tension gear wheel caterpillar (2 pcs.); 13 - axis of support rollers (steel, circle 10, 5 pcs.); 14 - Mounting axis (nut M10 and spring washer, 20 pcs.); 15 - remote sleeve (duralum tube); 16 - rink (18 pcs.); 17 - Bearing node (4 pcs.); 18 - drive gear wheel caterpillar (2 pcs.); 19 - drive shaft of the caterpillars; 20 - drive star of the drive shaft (driven asterisk 2th degree of chain transmission), z \u003d 18; 21 - the sleeve of the swivel fist of the steering ski (pipe with a diameter of 30 mm, 2 pcs.); 22 - front axle beam (pipe with a diameter of 30 mm); 23 - Kosinki, 4 pcs.; 24 - submool rack (pipe with a diameter of 30 mm); 25 - Bandage Roller (Rubber Ring, 18 pcs.).

You can take caterpillars from the old "Buran" to build a mini-version of the snowmobile and modify it by rooting almost an entire meter. The gears can be performed from a capron leaf, 1.5 cm thick.

Drive shaft

The drive shaft of the caterpillars (tensioning shaft is the same, only pos.4, replaced by position 1): 1 - left (along) tip (steel, cylinder 22); 2 - shaft (steel pipe 0.28x20; 3 - flange of fastening of the gear wheel to the shaft (steel sheet S4, 2 pcs.); 4 - right (along) the tip of the shaft (steel, cylinder 29); 5 - gear wheel drive wheel (2 pcs.); 6 - spar frame, 2 pcs.); 7 - Bearing housing cover (steel, 2 pcs.); 8 - Bearing 80204 (2 pcs.); 9 - Bearing hull (steel, 2 pcs.); 10 - shaft drive asterisk; 11 - Fastening asterisks to the shaft (M12 nut with wide and spring washers); 12 - sword (steel 20); 13 - seal (felt, 2 pcs.); 14 - fastening the bearing housing to the spar (bolt M6, with Grover 4 sets); 15 - Fastening the bearing housing to the spar (bolt M6 with a spring washer, 4 sets).

The drive shaft is made of steel pipe, a diameter of 1.4 cm. Special flanges are attached to the shaft, to which the gears are attached. At the end of the drive shaft, through welding, the tip-axes are mounted. There should be a place for the installation of bearings on the tricks.

Engine

This unit is considered the most responsible snowmobile mechanism. Compared to other elements of the design, such as a tire or chain, the engine must work properly and without it, no snowmobile will not move. Therefore, the long-term efficiency of the device will depend on reliable and trouble-free operation of the engine. If you want to install the engine from chainsaws, imported production, then you can purchase a used "Shtil".

Another important structure of the design, on which the trouble-free operation of the snowmobile depends, the gearbox is considered.

Asterisk

Immediately, the fact that the right tip has a key groove for installing and fastening a chain-transmission sprocket. This is an asterisk of a crawler shaft, which is securely attached using the nut. To make the fastening it is possible, the corresponding thread is cut on the tip.

The tip of the tension shaft has the same dimensions, and the fastening of the structural elements is carried out similarly to the attachment of the crawler shaft asterisk.

At the first stage of the transfer, an asterisk with the highest gear ratio (by the number of teeth) should be. On the engine chainsaw "Ural" you can count 38 teeth.

Steering

On a homemade device, you can install the steering wheel of any design and even from the bike. In this case, it is very important to take the steering wheel control of engine turnover. To hardly bother, it is better to use the steering wheel from the moped, a scooter, etc., where the engine power control mechanism is already provided. This will make the design more reliable and convenient to manage.

Brake system

Usually, such a vehicle has no brake system, and it is not necessary, since the snowmobile does not develop high speeds, the more homemade. Although, if you seriously approach this problem, you can build a primitive braking device.

Immediately, it is worth paying attention to that a homemade design, so that it is neither of themselves, it is unlikely to be able to register (legitimize) in the relevant authorities. And therefore:

1. According to the law, the homemade snowmobile does not apply to the category of vehicles. Therefore, its further use, as well as responsibility for the consequences, fall exclusively on the person who did it. It is better if it is operated somewhere in the outback and do not come across the eyes of the relevant services.
2. Snowmobile and floating all-terrain vehicles are absolutely different devices, although they have a certain similarity.
3. Since the engine has a small power, then cargo transport is not desirable to transport this vehicle. It is better to move on it alone.
4. For movement at night, the lighting (headlights) can be installed on the snowmobile. This will increase the functionality of the device and comfort when moving.

Conclusion

Due to the fact that most people do not have the skills of self-making any structures, they believe that it is quite difficult to collect a snowmobile. And if you manage to build something like a snowmobile, he is unlikely to go, and if he goes, it will stop very soon. And it will not be like a snowmobile at all, but on the pile of spare parts collected together. Fortunately, this is not as well as with the proper approach and the level of fantasy, you can collect a similar structure from the submitted means, which at least "PRUD" in any garage. And if there is at least any experience with these spare and infirm materials, the task is simplified at all. The principle of desire is already beginning to act here and if it is not, it is hardly possible to collect anything at all, not to mention a snowmobile.

The fact that the problem is currently in our time is not just a statement, but a belief based on the problems of today. Unfortunately, the state does not go to a meeting with wide sections of consumers, but took a course on the production of only expensive equipment designed to implement the consumer with money.
