Skis with motor on snow. Snowmobile based on a walk-behind tractor, photo and video description

03.01.2022

My homemade snowmobile with a rubber track, it was able to move not only on shallow snow, but also on almost any off-road.

The only thing it lacked was stability on slippery roads. To eliminate this drawback, I decided to install two steering wheels on my snowmobile.

Then it will be possible to drive not only on compacted snow, but also on open ground.

The large support area of ​​the track allows the snowmobile to overcome off-road conditions, streams and steep climbs.

Snowmobile design

The snowmobile is a two-seater, capable of towing several sleds with children. The frame is welded from square metal pipes, the footrests and skis are wooden. In the design V. is used four stroke engine 9 hp

Such engines have a gearbox that reduces speed by half and an automatic clutch in an oil bath. They are used on mini-tractors, walk-behind tractors and other garden equipment. When making my snowmobile, I took some components and parts from the Buran snowmobile: a caterpillar track, two pairs of bogies with four rollers, a caterpillar driven shaft assembly and drive sprockets. I bought all this in stores that sell spare parts for snowmobiles.

Rollers on trolleys « Burana"are attached asymmetrically, but I remade this knot so that their pairs are located symmetrically. To do this, I connected two carts using bolts and a special frame made of a 20 x 20 mm profile.

A rear pendulum with a driven shaft and rollers supporting the track (wheels from a children's scooter) was attached to the resulting balancer of two bogies.

The entire caterpillar structure (Fig. 1) is attached by the rear pendulum to the base of a rectangular snowmobile frame made of a metal pipe with a cross-section of 30 x 30 mm and a wall thickness of 1.5 mm.

The steering control for the snowmobile was made using ordinary plumbing threaded couplings and fittings, which made it possible not only to simplify the design, but also to do without complex machine tools. I have already done similar ski control on many of my homemade snowmobiles, and it showed itself perfectly during operation.

Manufacturing of racks

The ski swivel stands (Fig. 2) are made of a 3/4″ diameter pipe, with a half-inch pipe pressed into it to give additional rigidity. The racks are also attached to the steering beam using plumbing fittings and couplings.

The ski rack is inserted into a bracket, which is screwed into a coupling welded to a transverse steering beam with a cross-section of 50 x 50 mm on the frame. When the nut is tightened, the strut becomes wedged. This way you can adjust the height of the stand and the toe of the skis without changing the length of the steering rod.

If you drive a snowmobile only on loose snow, then the attachment of skis to the racks can be made rigid. With such a suspension, the snowmobile will be more stable on loose snow.

If you have to ride on compact roads, then it is better to make the ski suspension with springs or shock absorbers to reduce shock loads on the racks and frame.

I used coil springs for the suspension, which are installed on the bogies of the Buran snowmobile. They are on sale and inexpensive. The stiffness of two springs on each ski is quite enough.

For the snowmobile, I adapted wooden hunting skis, shortening them to 115 cm. To prevent the ski from going under the hard crust, but destroying it, I attached a special arch to the top of the toe, and installed a metal skate from below, which makes it much easier to control the snowmobile on a packed road.

Since the sled is aimed primarily at teenagers, I felt it necessary to lower it maximum speed up to 15-20 km/h by reducing the speed transmission from the engine to the drive shaft of the caterpillar. But this made the traction force greater, which makes it possible to tow several sleds with children. The snowmobile is controlled by one motorcycle-type throttle control. In order to start moving, it is enough to increase the engine speed - this leads to the centrifugal clutch being activated, and the snowmobile begins to pick up speed. When the gas is released, the centrifugal clutch disengages the drive and the snowmobile stops.

Homemade snowmobile: wheels instead of skis

To replace the front skis with wheels, there was no need to make any changes to the design of the snowmobile. Having removed the skis, I replaced them with hubs and wheels from a sports kart. True, we had to make specially elongated wheel axles.

During the first tests of a snowmobile with wheels, I realized that the design was quite workable - the car listened well to the steering wheel and held the road. But for rough terrain and dirt roads with deep ruts, the wheel diameter was clearly too small, and spring suspension without shock absorbers it turned out to be weak.

We had to modify the ski-wheel mounting racks to install a shock absorber from a moped and make an adapter disk for mounting larger diameter wheels from a Tula motorcycle.

The car with these wheels began to not only overcome deep snowdrifts in winter, but also cope well with muddy dirt roads. Low ground pressure due to the wide rubber track provides the all-terrain vehicle with good cross-country ability in any road conditions.

Rice. 2. Design of the steering gear of a homemade snowmobile:

1 – transverse steering beam; 2 – drive with external thread; 3 – coupling with internal thread; 4 – steering bipod is welded to the squeegee; 5 - Tie Rod(profile 20x20 mm); 6 - M10 nut 25 mm long; 7.8 – rotating ski stand (3/4″ pipe); 9 – ski hinge bracket; 10 – pipe 1/2″; 11 – M10 nut is welded to the stand; 12 - lock nut M10; 13 - M10 hairpin.

Today on the Internet you can find many instructions and drawings on how to make a pneumatic snowmobile with your own hands. Before moving on to developing circuits, it is necessary to find out what is special about pneumatics. The homemade device consists of a control support ski and a leading support pneumatic.

The rear axle of such devices has a rather primitive structure; it is usually made independently. The shaft is presented as a single piece, unlike the shaft in conventional snowmobiles. Both wheels are driven, there is no differentiation at all. The differential structure in this case is compensated by the stable design of the hull, resulting in an increase in the overall maneuverability of the vehicle. A significant disadvantage is low maneuverability, although this disadvantage can be smoothed out with special technical features.

The leading ski has two side cuts, which greatly improves traction on snow or ice. Is duralumin used as a material for making corners? This metal, like nothing else, increases ride quality in snowy areas.

The shaft moves due to the tension of the chain, the housing is fixed in the required position. Low-pressure pneumatic tires do an excellent job of shock-absorbing snowmobiles, and special cut tubes are often used as a supplement. Typically, pneumatics for traveling on snow are created from the following parts:

Together, these elements provide excellent control and uninterrupted shock absorption for the machine. Shaft sprockets must always meet the following parameters:

  • front? 8 incisors;
  • back? 28 incisors.

Thanks to this resonance, the speed of the machine increases and the shock absorption improves. The above parameters are optimal for snowmobiles.

It is worth paying attention to the fact that main characteristic any snowmobile is traction gain; the quality of movement and safety will depend on this parameter. Typically, snow machines don't go faster than 50 km/h? Perhaps everyone will agree that this is the optimal speed for a good device. A car on pneumatic wheels does not weigh much, but its engine power is quite high. With these characteristics, the device can cope with steep slopes and difficulties on snowy roads. Proper structure and high-quality construction can ensure the transportation of cargo or passengers whose total weight does not exceed 100 kilograms.

Relevance and features of operation

A pneumatic snowmobile has a number of positive characteristics compared to conventional snowmobiles:

  • quite high speed;
  • high depreciation;
  • ease of control;
  • simple structure;
  • powerful engine;
  • resistance to breakage and deformation.

Even if a breakdown does occur, it will not be difficult to repair the device with your own hands, even in the most severe conditions. Today, snowmobiles with this structure are increasingly used. A homemade machine will give you a certain level of freedom, since you can easily customize the machine to suit your parameters and needs. To make snowmobiles with your own hands, you do not need high qualifications and knowledge in the field of engineering; you can make a snowmobile from old parts from vehicles and scrap materials. You will have to buy a minimum of spare parts if you have old motors, tires, large transport skis and bearings lying around in your garage.

Be careful when choosing a motor for your device; it should not be too powerful, but durable enough. The optimal parameters for the motor are:

A pneumatic machine with such an engine will consume a little gasoline without losing maneuverability, power and speed. Some of the highest quality motors are engines Japanese assembly, such devices are time-tested and tested.

Before you start making a machine, make sure you have:

  • device for bending pipes;
  • welding machine;
  • small necessary details.

Of course the engine will play in the creation vehicle the most important role.

Snowmobile assembly instructions

To create a high-quality pneumatic snowmobile, you first need to think about the forced air cooling. To create it, you just need to put a special extension with a pulley in two streams on the knee shaft. From this device you need to run belts to the generator and two fan impellers to ensure rotation.

You can quickly carry out these simple operations with your own hands. Then you can proceed to creating the device fuel pump, it is better to place it on top of the oil pump cover drive, the fuel pump must be connected to the shaft oil design. It is best to use a fuel container with a volume of 30 liters; it must be hung under the frame from the body, near the rear of the axle. Great option The fuel pump will be a device from ZAZ-965A.

Next you need to install the filter and carburetor. Air filter you can also borrow from the ZAZ-965A, and the K-127 is suitable as a carburetor. The final stage of the design will be the installation of the ring gear; it must be mounted on the flywheel using an adapter. Don't forget to cover your homemade snowmobile with a hood; a galvanized steel sheet is perfect for this. You can create other elements for pneumatics with your own hands; wheels for it can also be homemade. Let us remind you that for this you will need:

  • chambers with low internal pressure (wheels from a tractor trolley can be used);
  • frame disks (sizes must be selected individually);
  • bandages from transport belts.

Knowing the entire sequence of actions and instructions for constructing a snowmobile, you can quickly and easily make a budget vehicle for snowy roads!

Many owners Agriculture They know firsthand what a walk-behind tractor is. It is used to cultivate a small land area. Most often it works in the warm season, but not everyone knows that it is possible to convert a monoblock into an all-terrain vehicle. Anyone can make such a vehicle with their own hands. If you have a small amount of money, the device can even turn into a snowmobile or ATV.

Do-it-yourself snowmobile from a walk-behind tractor

Homemade vehicles from a walk-behind tractor come in a wide variety. Most often, craftsmen convert it into a miniature tractor. The only difference is high level comfort compared to the original version. When creating, it is necessary to take into account several important details: shifting the center of gravity, increasing the front axle and installing a new differential. Nowadays there are entire kits on sale that allow you to improve the functional features of the candy bar.

For those who want to drive on snowy roads, there is also an optimal solution. Making a snowmobile with your own hands is quite simple. The most difficult task is the development and installation of a chassis on four wheels. A feature of such a device can be considered the minimum pressure on the surface. It is best to make special devices for coupling to the ground. To do this, they are made in accordance with the wheels of the walk-behind tractor.

For owners of heavyweights, everything is much simpler. The structure of the vehicle remains virtually unchanged. Here you will only need to secure the lugs to the surfaces of the wheels.

Homemade all-terrain vehicle from a walk-behind tractor

It is necessary to determine the capacity and carrying capacity of the all-terrain vehicle. It is best to prepare drawings in which the location of the units and components must be indicated in advance. Experts recommend installing an engine that uses a forced cooling system. These include air- and water-cooled motors. Its power must be selected at your discretion.

For many, it is unclear which type of engine to choose - gasoline or diesel. Here you need to be guided by personal preferences, since both have their own disadvantages and advantages. Chassis must have independent and floating suspension. To make it, you need to think through everything, but if successful, ride comfort will be ensured.

First you need to choose the type of base. For such purposes, the frame of Izh, Ural or Dnepr motorcycles is perfect. Special attention I would like to focus on the Izh-based base, as it has good handling. To have a floating suspension, we need to connect the side members with a strut with a bushing and a strut. The suspension will then allow the vehicle to ride smoothly.

As for the wheels, it is best to use a truck tube. A metal hub is most often used for fastening. KamAZ vehicle cameras are very popular in the production of all-terrain vehicles. Installing units is one of the most labor-intensive processes in the manufacture of an all-terrain vehicle from a walk-behind tractor. This step occurs after installing the suspension. In parallel, it is necessary to connect and adjust the brakes, clutch and exhaust system.

Once the all-terrain vehicle has been assembled, it needs to be tested. If there are any malfunctions, they must be corrected immediately.

Do-it-yourself swamp vehicle from a walk-behind tractor: important details

To make a swamp rover, you will need the same things. The only difference is the need to use wheels low pressure. They provide good off-road performance and also allow the vehicle to move through obstacles without any problems. When manufacturing, it is necessary to take into account the weight, since a swamp vehicle that is too heavy will have problems when driving.

Some people design a swamp vehicle based on a tracked one. Of course, this option is ideal for riding on mud or soft surfaces, but it is more difficult to develop.

Crawler all-terrain vehicle made from a walk-behind tractor: design features

Track-based units are most often found in rural areas. To make it yourself, you do not need to change the entire chassis. You need to purchase a large truck wheel of a size that can easily be secured and held between the front and rear wheels of the walk-behind tractor.

First you need to remove the side of the new one. Due to its thickness, this will be difficult to do. Next, we pull the resulting rubber “caterpillar” onto the walk-behind tractor. If, when testing a vehicle, a rubber tire slips, then it is best to choose optimal size. This option is the most affordable and easiest to produce. The service life of such “caterpillars” depends on operating conditions.

Of course, you can completely improve and replace the chassis, but this will cost a decent amount and you need to spend a lot of effort. True, there is one thing - the grip on the road will be better.

The winter season, beloved by many, has arrived. Active fun in the fresh air is the key to immunity and good health. What about winter games? Sleigh rides, ice slides, skiing, ice skating. These are traditional activities. If as a child it is very interesting to ride a slide, then as an adult you want new, more extreme sensations. A modern invention comes to the rescue - a snowmobile.

This is where you can turn around. A real gift for lovers of outdoor activities. However, its cost quickly dampens the activists' fervor. What to do in this case? Back on the ski slopes? In no case. You have a head on your shoulders and skillful hands - use them and make your own snowmobile. How to make a snowmobile with your own hands? Don't think it's that difficult. In fact, almost everyone can do this. You just need to listen to the following recommendations.

Coming up with an idea and doing it are two different things. Many are afraid to take on self-production precisely because it seems to them that assembling a snowmobile is a very complex and almost impossible process. In fact, this is not true at all. All you need is the right approach to work.

So, you decided to assemble a snowmobile yourself. You shouldn't get to work right away. This won't lead to good results. You need to be well prepared:

  1. think about why and when your snowmobile will be used;
  2. can you assemble the model yourself or will you need outside help;
  3. what parts made of ferrous and non-ferrous metals do you have in stock;
  4. Do you have the necessary tools for the job? If not, ask your loved ones or neighbors in advance;
  5. calculate what financial budget you can count on when assembling.

Can we?

How to make a snowmobile with your own hands? This will require technical knowledge and skills. If you are not sure that you can cope with the task on your own, ask friends or relatives for help. Perhaps they can help you. If they are not confident in their abilities, it is better to postpone the process of assembling the snowmobile until you have independently studied all aspects of its manufacture and are 100% sure that you can cope with the task.

Remember that any snowmobile, even one made according to the simplest design, is a rather complex technique. If you have never encountered the repair of vehicles or the repair of complex technical devices, be sure to take a partner as your assistant.

If you or your partner have the so-called “golden hands”, then for you assembling a snowmobile, even one made according to the most complex instructions, will seem like just the process of assembling a children’s construction set. Therefore, feel free to get to work and use the most complex drawings.

What materials are needed

Before you start studying the drawings and instructions in detail, think about what you will assemble the model from?

To do this, it is worth analyzing the contents of garages and basements, asking neighbors and friends, and walking along the market rows. Once you have approximately determined what materials can be used during assembly, you can begin the first stage of work.

So, first we need to determine what material will serve as the basis for the main part of our snowmobile. Skilled craftsmen will tell you that you can assemble a structure from anything. From whatever comes to hand. The most common options for materials used:

  • bicycle parts;
  • motorcycle parts;
  • parts from a moped;
  • just improvised means for any type of transport.

Depending on which part will become the main one in our assembly, the entire subsequent structure depends. Many craftsmen recommend making a snowmobile from a motorcycle, because its design is most suitable for “snow transport”. Experienced craftsmen also claim that on a snowmobile made from a motorcycle, you can feel all the power and strength of the vehicle. An unforgettable experience is guaranteed.

If you don’t have any of the proposed types of transport at hand, don’t despair. Find or develop manufacturing drawings, and assemble the model yourself from what is at hand. You can consult with more experienced professionals.

We develop the design

Once we have decided on the types of materials to be used, it is necessary to develop a basic work plan and select an assembly design.

To make a homemade snowmobile with your own hands, you will need to analyze your knowledge, skills and capabilities and choose one of the options for doing the work:

  1. making a model in accordance with instructions and drawings;
  2. self-assembly, depending only on your skills and imagination.

If you are a true master of your craft, then you don’t have to use standard drawings and try to make a model yourself in accordance with your preferences and wishes.

How it works?

The most important thing in self-assembly and manufacturing - understand the basic principle of the model. Once you understand how a snowmobile works and what makes it move, you can figure out for yourself what parts we need to get the job done and where they should be installed.

What are the operating principles of any snowmobile, including homemade ones:

  1. In order for the model to be able to stay on the snow and hold you and passengers, it must have a wide support area. Its dimensions should be as large as possible. Its stability and performance depend on this;
  2. weight of the structure. Everything is clear here: the less our device weighs, the easier it will be for it to move in the snow. Therefore, when assembling, pay attention to the weight of the parts.

Approximate design options

Based on studying the operating principles of our homemade transport, we can develop approximate diagrams of what the model will consist of and what will set it in motion:

  • we use 1 caterpillar as the main driving force, and install 2 skis as an additional one;
  • The main driving force consists of 2 tracks. 1 ski is used for supports.

This design is based on basic physical laws: in order for the model to stay on the snow, we need to use 3 support points. In order for a snowmobile to move independently, a driving force is required. It acts as a caterpillar. To ensure an optimal level of gliding on snow, you must use skis.

Self-assembly

The simplest option for assembling the product consists of using a motorcycle and additional tools.

Approximate step-by-step instruction self-made:

  1. install the front support ski. To do this, you can remove the front wheel and install a ski instead. The design allows for the wheel to remain in place. In this case, the ski is mounted on it;
  2. increasing the support area. For this we need a wide metal sheet. We fix it just above the rear wheel. In order for the rear wheel to rotate freely, we make a slot in the metal sheet according to its dimensions;
  3. on rear wheel We fix 2 track blocks (left and right).

If our design consists of 2 skis and one track block, the assembly steps change slightly:

  1. On the front part we install and secure 2 skis. Front wheel remove;
  2. we increase the surface area of ​​the structure using a metal sheet;
  3. on the rear part, remove the wheel and fasten the track support instead.

This design can also be modified. To do this, we install a caterpillar on the front part, and 2 skis on the rear.

We need durability

So that our homemade model It has served for several winters and needs to be looked after carefully. Operation of a snowmobile should be as careful as possible:

  • After each use of the structure, it is necessary to carry out wet cleaning. Suitable for this detergents for cleaning cars;
  • try to prevent water and moisture from getting into the engine parts;
  • lubricate the main parts of the model silicone grease or a special spray;
  • In summer, it is better to protect the engine from damage. To do this, you need to take an oiled cloth and secure it to the muffler.

Every agricultural owner knows what a walk-behind tractor is. This machine is traditionally used in gardens, although it is often used in the work of public utilities. When this device breaks down or the “season” ends, many people hide it, but you can make an all-terrain vehicle or snowmobile with your own hands from a walk-behind tractor.

What can be done

Most often, in winter, walk-behind tractors are hidden in the garage, because it is not suitable for use in snow. But since any equipment needs periodic mileage, you can make an all-terrain vehicle or snowmobile out of a walk-behind tractor to use it at any time. The device is easy to recycle due to its design.

Overcome impassable areas

The all-terrain vehicle has many advantages, because it has. Since complete asphalt pavement is quite rare in rural areas, this device will be able to drive on any surface, even snow. To create it you will need a walk-behind tractor with a two- or four-stroke engine. It is important that it has air cooling.

In the future design, the walk-behind tractor will serve. To do this, you need to remove the axles and steering wheel from the walk-behind tractor. Next, you need to insert the frame so that the cardans act as bridges. It is important not to spend complete redesign walk-behind tractor so that you can return the original device at any time.

Put it together

There are many design assembly options. It all depends on the type of future device and its capacity. The chassis of an all-terrain vehicle must have independent suspension. It is better to supplement it with low-pressure pneumatic wheels. The frame can be either articulated or solid - it depends on the type.

To provide the car with independent support, it is necessary to connect the side members with a strut, a stand and a special steering bushing. To attach the wheels, you need to install a bladder from the truck to the suspension (it's better to use a low pressure chamber). After installing the suspension, install the motor from the walk-behind tractor. At this stage, the brake, clutch and gas release are connected. Such a device shows excellent maneuverability at a speed of 75 km/h.

Movement through massifs of snow

In order to make a snowmobile from a walk-behind tractor, you will need power unit, welding machine, tracks (best constructed from shipping tape), although wheels can also be used. All parts are assembled on the basis of a drawing, the drawing of which is carried out only after the type of future apparatus has already been decided. It is quite difficult to move, a snowmobile can overcome almost any snow blockages.

Before starting work, you need to decide on the purpose of the device. Its load capacity and power depend on this. It's best to start with a cardboard mockup to help guide you in the right direction. Many parts are available, you don’t have to buy them. It is best to choose tracks rather than wheels, as they will make it easier to move through the snow.

Stages of work

Initially, you need to create a frame, for which you will need pipes from a motorcycle. They are given the required shape using a pipe bender, after which point bonding is carried out by welding. All parts are connected with a continuous seam so that there are no open joints. After this, the bracket is welded to the frame element and the seat is attached. The future purpose of the device depends on the selected power and reliability of components.

To install the steering wheel and seats in a homemade snowmobile from a walk-behind tractor, you can use any surface, be it an old chair or steering bicycle. The number of seats for passengers also depends on this. It is important to skillfully approach the work, because all elements of the device must be securely fastened and work harmoniously. This will allow you to convert the walk-behind tractor into a snowmobile that can cover large areas even in a strong snowstorm.

Many people know how to make a snowmobile or all-terrain vehicle from a walk-behind tractor. craftsmen. This is a rational use of a device that is normally unsuitable for use in winter. The main advantage of such manipulations is that after a cold season the structure can be returned to the form of a walk-behind tractor.

To prevent the walk-behind tractor from being stored idle in the garage, it is much better to convert it into a snowmobile or all-terrain vehicle. But such manipulations must be performed very carefully to avoid mistakes and prevent accidents. Also not recommended
