Installing the engine to a quad bike 125 cubes. Homemade quad bike with the engine from the car

Pretty many hunters, fishermen, and just lovers of outdoor activities are dreaming of their quad bike. But prices are even on used equipment, most of the pocket, not to mention the new technique. It is not worth a despair, because today we will learn how to make a quad bike with your own hands! These are excellent transport for business needs, for the transport of trailers with high patency due to a short wheelbase, as well as easy to manage. But you immediately want to say to make homemade quad bikes will need a lot of time. As practice shows, the project can take from 6 to 12 months on average.

Preparatory stage

So, proceed. First prepare the tool and equipment. It will take a lot of welding, for which manual electrodeshic welding is quite suitable. Choose electrodes for welding of responsible and vibration-loaded structures than and will be a quadrocycle frame. By the way, this very frame can be cooked with your own hands from conventional water pipes. Such easily find on the nearest taking scrap metal, or metal bondage. Choose a pipe diameter from 25 to 32mm, and the wall thickness should be in the 3mm area. For flexible pipes, it is advisable to have pipe bender, but if there is no, then bending the pipes for the frame frame can be and manually using the lever, heated the place of the desired bend by gas burner, and better gas-oxygen cutter.

Choosing the main parts

The next step will be the selection of the necessary parts necessary, namely:

• engine
• wheel
• shock absorbers
• rear bridge

If you want to collect simple light Quadrik with a drive only on the rear axle, it is preferable to select the engine from the motorcycle of the middle cabin, from 250 cubes and above. Depending on the construction budget, it can be almost any motor from soviet motorcycle, It is desirable with a chain transmission due to what it will turn out to simply make the rear axis drive. The axis can be made of pipe made of structural steel. In the center of welding the flanges for fastening the slave star and disk brake, and install on the sides hub bearings From the car, pre-pressing them into the buildings made in advance.

Cases serve to attach the axis assembly to the pendulum. The pendulum can be left standard, further enhance it and make a new mount for the disk brake caliper. Also, not forgetting to make fastenings for brake shogs along the pendulum.

The next task is the choice of wheels. And the ideal option is not only in terms of availability, but also in size will be wheels from the eye. The main feature is that such stamped discs are very lungs, perfectly fit in the proportions of the self-made quadrocycle, and most importantly, they are greatly suitable tires from factory quadrics, which will significantly improve the permeability. As it looks, you can see further:

Donor selection for a new frame

How to make a quad bike in the manufacture even easier? You can simply use the frame - the donor, for example from the Ural motorcycle, welding the rear axle to a regular pendulum and only a little change the front suspension! The thick frame of the Urals is made of good steel, has an excellent margin of safety. And the engine with a large torque as it is impossible by the way is suitable for such a purpose. As for the gearbox, it is better to use it from the Dnipro motorcycle. It is designed for good loads, it is characterized by the clarity of shifting gear, and the most important thing is the presence of the rear velocity, which is the mandatory function of a full-fledged quad bike. Photo Example of a self-made quad bike from the Urals below:

Steering

A quad bike assembly with your own hands the matter is not easy. And perhaps the most difficult thing to do it steering. To do this, first weld the frame of the front of the quad bike, then you will need swivel fists From the car, for example, from Niva, but any others are suitable. After that, you need to build suspension levers. Pay special attention to the design of the fastening of the levers, since large loads arise in their pairing with the frame, so there will be no additional ribs of stiffness. Levers are usually attached to bolts through silent blocks. This is a rubberometallic hinge which is a mandatory link in the suspension. It quenches the wheels of the wheels, not giving vibrations to be transmitted on the frame. Levers can be made according to data drawings.

Go ahead. What is the front suspension without shock absorbers? Here you can apply 4 motorcycle shock absorber one by one for each lever in front of the front, and two on the pendulum for the rear axis depreciation. Fit rear shock absorbers from Iza, but if you are ready to surpass on gas-insulated with a podachka, then it will give you the opportunity to adjust the suspension under road conditionsthat is very useful for such equipment as an ATV!

Four-wheel drive and automotive engine

And how to create a quad bike with the drive for all 4 wheels you ask? Above we reviewed the easiest option. But option is possible not only with a motorcycle engine, but also with a car engine! And then we will tell you how to make a quad bike with an engine from the eye. In the case of a all-wheel drive quad bike with a car engine, things are much more serious. Here you can already use a motorcycle frame as a basis, it will have to be welded completely from scratch under car Engine. By the way, he may not only be from Oka, but also any other depending on your desires and opportunities. Immediately do not forget about the system liquid cooling. Frame design calculate so as to place a radiator with a fan in a secure place from forest branches. The engine with the box should be mounted along the frame, in order for the drive shaft from the gearbox immediately to the rear bridge. To distribute the rotation of the wheels to each wheel, you will need 2 identical bridges, for example from the zhiguli. But for installation will have to shorten them. To increase the permeability, if desired, you can make a downgrade chain gearbox, aligning with a standard gearbox. At the same time, the leading gear must be somewhat less slave. Uncomplicated calculations of the diameters of these gears, you can learn how much will decrease maximum speed And the thrust will increase. If the quad bike is not planned to be used to ride on the roads of general use, it will be a very significant technical solution.

Enhance functionality

Now that frame and chassis Quad bike will be collected, the engine is installed, you need to think about secondary structures, thanks to which the technique will be practical. Fuel tank Well suits the Ural motorcycle. Its impressive capacity will be enough even for the car engine. An important modification will be the installation of "Snorkel". Since the engine in the frame is pretty low, then air filter accordingly takes the air from the bottom. To exclude water from getting into it when overcoming Brodov, it is extremely recommended to do it. Fully need to remake and exhaust system, with the output of the exhaust gases is pretty high levelso that the water does not get inside. Also for quad bike, you need a large wide seat by moving body weight, it will be possible to achieve better control when moving. From aluminum sheet metal, you can make the bottom protection for protecting the front suspension and engine levers. It is not superfluous in the forest will be the winch installed in the front. For lighting road, you can use fog car headlights.

Work on the appearance

In conclusion, to bring the Quad bike to the proper appearanceSimilar to the present you need a housing. To do this, you will need epoxy resin ED-20 and fiberglass. These components can be bought in a business or construction store.

To give such a form, first need to cut a blank from a dense foam, which is also sold in large building stores in the form of plates 1 m2 that is very convenient to create such projects. Then the fiberglass is applied to several layers. In this case, each layer is wedged by a resin. The more layers, the stronger the case. Do not forget about the metal fasteners that need to be inserted between the layers, in the future for which the housing will be attached to the frame of the quad bike. After drying, you can grind, grind and paint. Such a fiberglass case has a light weight and is very durable.

With a serious approach to business, such a quad bike is not enough to give up the factory, and on the cost of assembly it turns out many times cheaper. While collecting such a thing you can use the sea of \u200b\u200bdriving pleasure.

Quad bike is all-wheel drive car and motorcycle, bike enduro-cross, in one bottle. The peculiarities of this type of transport are compactness, tires with in-depth treads for better clutch With off-road, 1-2 seats and no roof over your head. For the first time, a similar type of transport appeared in Japan in the 1970s and conquered the hearts of many romantic off-road. Such transport will be interested in hunters, fishermen, lovers to conquer impassable terrain. Many of us dream of such a toy for adults. We will tell you how your dreams can embody your own hands.

Select the engine for quad bike

The most important detail for your all-terrain vehicle will be a power unit. Most often use motorcycle engines (they are economical and small in size). Let's say, the engine with "Urals" or "Minsk", Izh "Planet" or Izh "Jupiter". You can adapt the engine from "VAZ" or "Oka" to your quad bike. To avoid overheating of the engine in the heat, you need to choose a model with an air cooling system. The most popular option is to transfer automotive forced cooling.

Modernization of the existing frame or drawings from scratch

Before all the undertaking, a plan of action and a drawing of a design or ready frame is necessary. If you yourself are friends with mathematical calculations, you can do everything yourself. If you don't do the drawing, you can contact a specialist or search for a suitable design scheme on the Internet.

The easiest way to take the ready-made frame from the motorcycle and to fight all the missing details on it. The order of your actions is as follows: We disassemble the old motorcycle. We only leave the frame. The back of the frame with the fastening of the pendulum fork is cut off. Tubes extend the frame and weld the brought the bridge (use drives and brazers). Car bridge pre-turn over the quadric to go ahead, and not back (because on the "Uralsk" gearbox at the output direction of rotation of the opposite).

Remember that in the event of a replacement, the bridge reducer should be easily removed. We are looking for spare parts from the passenger cars: 2 Front hubs, rear axle (so that the disks coincide with the fastener with the hubs), the cardan shaft, the front suspension levers, transverse steering rods, the round plumbing pipe ¾ inch.

If there is no donor motorcycle, then the frame is best made from durable alloys: pipes, profiles cooked with point welding. For the carrier parts of the frame, you can buy water pipes (25 × 3.2 VGP). You must have equipment that will be flexing the pipes in the right place. For the body, we boil the frame from the pipe 70 × 40. The length should not be shorter than the springs, but the width correspond to the size of the bridge. Using driven, do not forget about the rigidity of the design to twist.

"Uralovskaya" rubber clutch connect a cardan with a box. Through the hinge crossbar flange connect the cardan with the bridge. If the donor was IL, the drive is carried out by the native chain.

If your quadric is with springs on shock absorbers, then the rear pendulum pendant leaving along with silent blocks. We breed the bridge to the fork (do not forget to strengthen the seams with wide jams so as not to break out later). Instead of cardan, use semi-axes from the eye or vase. Springs with shock absorbers leave as it is, do not touch. When the frame design is ready, proceed to the engine mount on the bottom of the frame with bolts. The engine may be rear, and in front (no difference). The silencer can be homemade, two-piece.

Now on the rear wheels with a qualitatively mounted transmission so that the backlash is not formed. The drive comes along with the engine from the outdated motorcycle. Wheels on quadric can be supplied from "Niva". If you need a trunk, it can be welded from thin-walled steel pipes. Bumper can replace "kenguryatniki".

Management type

To ensure that your all-terrain vehicle is safe, you will have to take care of the type of management. On your Quad bike can be 2 types of control: the steering wheel (the basis take from the car - steering traction) and the steering wheel from the used motorcycle (lever and shaft). The steering shaft can be made from the pipe with a diameter of 20 mm and the wall thickness is 2.8 mm. At the bottom end, place the stroke limiter. Thus, at the bottom of the shaft rests on the stubborn bearing, and in the middle turns into the junction bracket-sleeve.

Suspension: Front and rear

On your Quad bike, you can install the suspension or rear or front. For the rear suspension, such a solution will fit:

1. So that the design is lightweight and simple, the gearbox-cardan system is needed. Differential in this case is absent.

2. Very hard work design, if used car Most (it has to shorten). In this case, there is a differential, which will be needed when moving.

For the front suspension, you can take the basis of the suspension from the "Ural" or Iza. The installation of the front suspension is more beneficial in time - it is faster than four-wheel drivewhere you need help professional turners, electricians, welders (there will be a certain refinement).

For fastening pendulum levers, the front of the motorcycle frame is lengthened. It is necessary to install so that the rotating wheels do not hurt the engine cylinder. Therefore, on the "Urals" frame, the wheels are fond of forward. For increase geometric passability, pendant levers must be as long as possible.(These must be made by yourself). To the steering column (made from the "Uralovsky" cardan) at the bottom we weld along the two steering bumps: on the right and left wheel. The hubs are fastened with native balls.

When installing the front rack, do not forget about the slope of the rack. This will prevent the steering wheel knocking on the bumps and help return the steering wheel in place when turning. If there is no inclination, you can fly by inertia, the return of the steering wheel in the opposite position will be very problematic.

All-wheel drive quad bike

For all-wheel drive quad bike you will need:

- Drive OT. mechanical transmission with the power selection gearbox on the front wheels;

Wheel differentials;

Steering on the front wheels (on the principle of the car);

Independent suspension (can and multi-type) or dependent suspension.

If there is no possibility to assemble all, take the suspension from the "Oka" or front-wheel drive vases. Cook the frame from scratch under the engine with "Oka". In the front suspension, leave a place for the drive gearbox of the front wheels. It can be done by himself: cutting the "stockings" of the bridge and we derive suitable semi-axes from the VAZ from the differential. The engine is deployed by the back forever. Now the semi-axes became cardanes, which lead to the movement of the front and rear axle.

How to make homemade quad bikes - a question that is the dream of almost any young designer.

However, this kind of dreams are carried out far from all and far from at that age in which I would like. But sometimes the dreamers still embody the desired reality.

Drawing skills, the ability to perform complex technological processesThe estate and time estate is the basic requirements when creating a self-made vehicle.

Today we will tell you about how to construct homemade quad bikes, using spare parts from Oka and show this process using photo selection.

Learn one of the ways and make sure that the realization of the independent creation of a quad bike from automotive parts It is possible in the example below.

All-wheelwater quad bike on the basis of the car "Oka" with their own hands (Lover Designer Sergey Pletnev)

To begin with, give general characteristics Project:

• Length - 2300 mm;
• Width - 1250 mm;
• Height - (extreme points of the wheels) - 1250 mm;
• Base - 1430 mm;
• Clearance - 300 mm;
• Engine - got from the car "Oka";
• Wheels - discs: "VAZ" 2121 (Niva);
• Tires - coordiantoffroadr15;
• Shock absorbers - "Oka";
• Hubs - "VAZ" 2109;
• Inter-wheeled gearboxes - "VAZ" classic
• Maximum speed - 60 km / h
• The gearbox taken from "Oka" was modified by replacing the standard main pair of gear on the chain drive.

Made it was to increase speed on roven road. And it looks like this:

Assembled

In disassembled form

In the form of carrier parts, the frames perform water pipes (VGP 25x3,2). Were purchased in the form of two segments of 7900 mm and weighing 38 kg in the amount of 1150 rubles.

For levers and suspensions, water pipes were also required (20x2,8) - two segments of 6100 mm long, 20 kg weighing 650 rubles.

Two used rear bridges from "penny" (VAZ 2101) - in the amount of 3000 rubles.

From the "eight" (VAZ 2108), fists assembled with discs, calipers and other steels of drives - in the amount of all these bu parts were spent 4000 rubles.

Metal sheets, nuts, bolts, washers, silent blocks, and others were useful - consumables and materials for such cases should always be enough.

From the above parts using welding, pipe bending and plumbing tools, this design was created.

With the help of welding, most structural parts are bonded. A carburetor was installed.

Metal plates for suspension, engine and bridges are also fixed with welds

The hubs are connected to the suspension new phthulates, washers and bolts

After the frame was collected, the miscalculations of the nuances of the engine position, the functional of the gearbox and its mounting, as well as the front suspension with the steering wheel, began.

As a result, the following moves were applied:

From the rear post, the semi-axes are connected to the hubs. Fastening for shock absorbers

In the gearbox applies the elongated stemman production

The picture shows how the fastening for the box and the position of the rod was connected

The swivel fist is taken from the "VAZ" 2109 and the steering tower is made of metal plate alone

After a small test drive, it was noticed that the stem from the box would need a scene to switch the hand gear - this is the most convenient option in the case of a modified box.

It must be said that it was modified to increase the gear ratio from the axis to the wheels, since without this intervention, the speed at maximum revolutions would not be given above 45 km / h.

Further assembly

Side steps are welded to the frame, the front axle is installed, a cardan from the gearbox is connected to the front bridge, the front shock absorbers are installed. The front edges are connected to the hubs and the bridge

Installed brake system Separately for the wheels

Installed steering and brake system for front wheels

Off-road rubber purchased (in this case, the most appropriate option)

The stage of creating a quadrocycle matrix occurred. Installed mounting foam, cardboard, resin, fiberglass, fittings, etc.

Technology application of materials when creating a matrix is \u200b\u200bvery difficult processrequiring a deep and detailed study

Light reinforcement and cardboard set frame wings, as well as front and rear pieces Facing. The foam was filled with a margin in places where convex forms were supposed to do.

The dried foam was processed with a furnace hammer, knife and other tools

An oil radiator from the helicopter was installed and the first layer of fiberglass was applied

The front suspension is completely collected. Native ball "VAZ" 2109 below. From above steering tip from "UAZ"

Quad bikes can be equipped with two types of engines: electric and gasoline. Electrical motors have less power and low energy. If you take an average quad circuit with an electric motor, the stroke reserve will be approximately an hour of time, and then a long battery charging is required. In this regard, such type of motor is equipped with children's models of quadrocycles.

The most common engines for quad bikes

Gasoline engines got the wider distribution in quad bike construction. They give high power, which in a pair with transmission is converted into a high torque. Thanks to this, quad bikes feel so beautifully on any off-road. Also, an important indicator is the specific capacity (power assigned to a unit of mass). The low weight of the motorcycle device in a pair with a good engine allows you to show four-wheeled amazing permeability. For quad bickers, motors are used with a working volume of about 49 - 900 cubes. Of course, there is a smaller volume that are intended for children's versions of devices.

The difference between gasoline engines for quad biccles

Gasoline engines for quad bikes can be divided into two large groups: two-stroke and four-stroke. The difference between these two types is that in the two-stroke engine one working cycle piston makes per move. In the four-stroke engine injection, compression, detonation and release is made in two stroke of the piston. Based on this, it can be said that the two-stroke engine produces greater power with the same amount of cylinders. For example, four-stroke engine Equipped with one of the most common quad bikes stels ATV 300. Many believe that in fuel two-stroke engine It is necessary to pour oil. However, this is not quite the right judgment, since there are many engines that do not require this, for example, Catarpillar motors do not require oil in gasoline. Of course, the conversations that the motors of the two-stroke design produce more harmful substances - This is true, but it should be understood that this is due to the greater frequency of fuel combustion in the cylinder. It can be noted that engineering technologies today are developed so much that motors emissions different types A little different and minimized.

Engine maintenance for quad bikes

Performance power aggregate Depends directly from the quality of service and frequency. Service maintenance two-stroke engines It is produced much more often compared to four-stroke. This is primarily due to the fact that in the cylinder there is more frequent combustion of the fuel-air mixture. As a result, it is achieved higher working temperature Engine. Such factors lead to a more rapid wear of the power unit operating on the two-stroke cycle.

Therefore, when buying a quad bike with a two-stroke engine, be prepared for more frequent maintenance and purchase of spare parts. The indisputable advantage of the two-stroke engine is its low weight, simplicity. But at the same time there are a lot of flaws: high oil and fuel consumption, high vibration and noise. The two-stroke engine is equipped, for example, an ATV-024-15 quad bike.

However, athletes and lovers to drive on quad bikes little attention to collect the engine, the most, perhaps, the main point in the choice becomes the output. By power, it can be noted, the superiority of the two-stroke engine in front of the four-stroke with the same amount.

It was going to purely for entertainment purposes, so the author was focused on industrial quad bikes and collecting their car. However, there are a number constructive differenceswhich have a positive effect on the passability of all-terrain costs and significantly allocate it against the background of quad bikes of standard configuration.

The machine has excellent quality of patency and reliability, largely due to a small weight.

During the construction of this model of self-made quad bike, the following parts and materials were used:
1) Water pipe diameter 32 mm
2) Pipe 27 mm
3) Engine internal combustion from car an eye 11113
4) gearbox from the same Oka
5) front and rear gearboxes from classic vase
6) hubs and grenades from VAZ 2109
7) Fiberglass

Consider in more detail the stages of the construction of this all-pass:

The suspension of the home theyight of the homemade design is organized with the help of A-shaped levers, which are made of a pipe with a diameter of 27 mm.

The engine and gearbox from the OKE car was installed, the differential was welded.

The gear ratio The ratio of the front and rear gearboxes is 43 to 11, they were redone under the inner grenades from the Lada nine.

Hubs were installed and disc brakes From the VAZ 2109, and the wheels are supplied 15 radius through spacers.

Initially, it was planned to make a clutch on the steering wheel like a motorcycle, but then it was still decided to make it under the left foot, despite the unusual solution for the quad bike, it turned out to be quite convenient by the author. That is, there are no problems with switching gear on the go. Moreover, the all-terrain vehicle is able to touch on any gear, even with a passenger on board, the engine power is enough. Therefore, transmissions are not switched as often, when traveling along the roadway, only the third and fourth transmission are mainly used, and the first and second of the road, respectively, are used.

Was organized transfer case The own design of the author, thanks to which it became possible to turn off the front axle. The following is a photo of the entire mechanism for turning off the front axle, where you can see the main elements of the details:

Works were performed on rear suspension all-terrain vehicle:

Frame preparation Machines for fiberglass pasting machine:

The process of fixing fiberglass by car:

Then the author began paining work on all-terrain vehicles:

A vulnerable design site, as you might notice from photos, are anthers on grenades. The author has not yet decided how to protect them from possible breaks.

In the following photo, the gear selection mechanism is excellent, as seen in the photo, the lever was slightly distinguished from the engine, since before that it was installed closer and the author often burned about the silencer, the likelihood of such an injury was taken on rear stroke. At the moment, the problem is completely eliminated by transferring the lever:

There is no photo on the radiator yet, and what exactly interests?

The radiator of all-terrain truck is hidden under the plastic right in front of the instrument shield, despite the fact that the hole that is existing is very small, it is enough to cool the machine. Although problems may occur when driving through strong dirt, since the hole is easily clogged, and the cooling from the incoming air does not work. But the fan copes with a similar load, although the all-terrain vehicle is not operated by strong dirt. In addition, the fan turns on only with truly heavy loads, which is extremely rare.

The reason for this is the fact that the device itself turned out to be quite lightweight and the engine from the Oka perfectly copes with the loads.

Below is a photo of the placement of the radiator:

Werethod has an approximate weight of about 450 kilograms.
Video tests all-terrain vehicle when driving through the snow:

If you watched the video, you probably paid attention to the singing rear wheel Already a few meters, which should say about the work of the rear differential. This all-terrain vehicle is very different from industrial, since they have no rear differential and rear axle Always rowing, which does not slowly interfere with the controllability of a quad bike, since the width of the car is small.

The author also wanted to initially brew the rear differential, but thought it would always be done, and decided to try to ride while differential. But since the passability of the all-terrain costs arranged and problems with rear bridge It was not observed, then there was no desire to disassemble the design and brew the rear differential from the author.

That is why the all-terrain vehicle remained with the rear differential.

The only author plans to install more serious wheels on the all-terrain vehicle. Either remove the supports for disks 15, by installing disks with a breakdown of 4 per 100 from the Logan or Opel, which are superbly suitable for the VAZ hubs.
