Tracked all-terrain vehicles visiting homemade products. Homemade tracks for a walk-behind tractor with your own hands. Engines for homemade all-terrain vehicles

One of the problems of our homeland is very bad roads... And therefore, some enthusiasts are trying to solve this problem on their own.

Just a huge amount highways connecting different villages and villages are so bad in their condition that it is sometimes problematic to drive through them in an ordinary car.

And when the autumn-winter period comes, it is almost impossible to move through them. You can, of course, get out of the situation and order an all-terrain vehicle from abroad, but it is very expensive and therefore you have to make do with what is available.

Homemade tracked all-terrain vehicle

This all-terrain vehicle high cross-country ability, for him is not an obstacle off-road, as well as any water obstacles. The body is made in the form of a box-shaped structure. Caterpillars are the driving force.

The hood is shaped to move through algae, driftwood and moss. Traffic fumes are retracted upwards. Homemade all-terrain vehicle on caterpillar equipped with a front winch. The body bottom is sufficiently sealed, plus pneumatic rollers are located on the sides, which have a positive effect on the buoyancy of the all-terrain vehicle.

Tracked ATV control

The control of the all-terrain vehicle is the same as on the tractor, it is carried out by levers. The side differentials were made from VAZ disc brakes.

In the cab, in the middle of the floor, there is a pneumatic lever - a track tensioner. The ideal option would be to use a mechanical tensioner, since it is more unpretentious to repair, but the author of this all-terrain vehicle decided otherwise and installed a pneumatic tensioner.

Chassis

The designer has created an excellent chassis. You should pay attention to the tracks: they are cast, made by ourselves. The tracks have lugs on the outside made of metal pipes welded to the metal sheet. This played a positive role in terms of flotation and traction.

This technology is not used in foreign all-terrain vehicles due to the complexity of execution and increased financial costs. The rollers are made of stroller wheels, protected by a rubber reflector. Also above the caterpillar drive, there is a "damper" made in the form of a rubberized half-pipe.

Tracked Off-Road Vehicle Engine

As power unit a VAZ engine with a gearbox was used. The connection of the rear axle gearbox is carried out by means of a coupling made of rubber. The gearbox is connected to the side differentials by shafts.

As mentioned above, the differentials are made from VAZ disc brakes with conventional calipers.

The resource of the reducer is not reduced at all due to the low speed of the all-terrain vehicle. The main advantage of this all-terrain vehicle model is its low weight. When the all-terrain vehicle moves on a swampy area or along a lake, the body sinks 30-40 cm.

Tools

When implementing this project of a homemade all-terrain vehicle, the following tools were used: a welding machine, a grinder, various keys. Clamps, a machine for giving one shape or another to sheet metal, this is especially important in the manufacture of the cab and the bottom of an all-terrain vehicle. Various bolted connections. Glass cutter for the manufacture of windshield and side windows. Drill for drilling holes.

Minsk resident Boris Karavkin. And recently Yuri Pidgaetsky from Molodechno decided to build an interesting homemade tracked all-terrain vehicle from a "Muscovite" and Volkswagen. What came out of the symbiosis of components and assemblies of the Soviet and german cars, read in our material.

"Come to Molodechno, we have made a caterpillar all-terrain vehicle here" - such a message came recently to the editorial mail. The designer did not manage to send the photos, so until the very last moment we had no idea what we were going to shoot.

And when we drove up to Yuri's house, they just fell out of the sediment from his all-terrain vehicle. Live this is something incredible! It seems that the car arrived in Molodechno straight from the set of films about zombies, the apocalypse or Mad Max.

Below - a caterpillar "cart", on top - a shortened body from "Moskvich-2141", painted in a military protective color. Live car looks very unusual. This has never happened before in our "Autoexotics" section!

“I have been fond of homemade products since childhood, I went to the circles of model designers, - says Yuri Pidgaetsky. - I made a variety of homemade products - a children's kart, a tricycle with tires low pressure... And two and a half years ago I started making a tracked all-terrain vehicle. For what? I don't really know myself - it's just that my hands are always itching to do something like that ... "

Before the trip, we will study the technical component of the "monster". A car was made without drawings - by eye. A solid frame is assembled from shaped pipes, sheathed with tin. A shortened body of a "Muscovite" was later installed on it. Yuri says that he fiddled with him the most.

The radiator and stove are located at the front. There is still room under the hood for various little things. So the car has almost two trunks.

There is no back row of seats. Instead, there is a huge trunk, under which the power unit and transmission are hidden. As you can see, the all-terrain vehicle turned out to be very practical.

The most interesting thing is hidden under the boot floor. Gasoline 1.8-liter engine from the old Volkswagen passat is almost in the middle, but unlike passenger car located not transversely, but longitudinally. Next comes a 5-speed gearbox from the same car with a welded differential.

From it - a kind of cardan to the rear "Zhiguli" bridge. Exhaust pipes brewed from scratch, fuel tank homemade.

The rear axle differential is naturally free. The torque is transmitted to the rear rollers. They also have brake discs from the old Volkswagen Golf.

As you already understood, brakes are needed not only to stop the car, but also to control it. We pull on the right control lever - we act on the caliper of the right roller, as a result, the car turns to the right. We pull the left lever towards ourselves - we turn to the left. There is no brake pedal - to brake, you need to pull on both levers.

Yuri made a caterpillar from a conveyor belt and metal shaped tubes for a week and a half. Conventional automobile rollers are used as rollers. wheel disks... Each track has a tensioning mechanism. According to the craftsman, the suspension is made from what was - on each side there are three struts with springs and shock absorbers.

Interior elements are taken from the same "Muscovite". Everything works inside, including the radio and the stove. Conventionally, the number of seats can be defined as 2 + 1 - in the cabin, albeit in cramped conditions, but three of us can accommodate. The gear shift pattern is inverted.

Now hold on to the chair - Yuri's all-terrain vehicle can swim! Everything is sealed inside - the "Muscovite" does not sink. True, so far there has not been enough courage for full-fledged water tests. The car drove into the lake, but held on to the bottom with the back of the caterpillar. The front of the all-terrain vehicle did not sink! In general, the car should float, but Yuri has no desire to fully launch it into the water - it's a pity to drown such a technique.

The armor is strong and our tanks are fast - we are going to test the equipment in the fields! By the way, the all-terrain vehicle has not yet been properly tested - Yuri drove it only a few times. So we, together with the designer, will probe its capabilities, positive and negative qualities.

But first you need to get into the car, and for this you need to remember the army days. You need to climb on a car just like in the army on an infantry fighting vehicle, that is, as you can, you climb.

First comment after our Instagram post: "Will the ATV roll forward with emergency braking?" We braked at low speeds - we didn't roll over. Still, despite the considerable height, the center of gravity is located low - where the engine, rollers and tracks are. Yuri developed before us maximum speed 60 km / h, slowed down, but not urgently - the car did not overturn. To brake strongly at high speed while there is no desire - first you need to install three-point belts and a safety cage. It seems that the car should not turn over, but in order to check this for sure, it is better to work on safety first. So, just in case.

You sit behind the wheel, ugh - with levers, very high. There has never been such a tall "Muscovite" in history! The cabin is very noisy while driving, but it cannot be said that this is a drawback. Noise enhances the emotion of driving. You really drive like in a tank.

I always dreamed of traveling on tracked vehicles, it's a pity that nothing was steered in the army. It's time to catch up!

The clutch and gas are just like in a normal car, nothing special. It is difficult to find the gears, the switching scheme is inverted, which blows up the brain, there are also problems with clarity, but you can choose any gear, because the car starts off at any speed, at least from third for sure. There is no "lowering" in the transmission, the lowered row in this car is already made by default, so in first gear you can climb at the speed of a turtle.

I turn on the gear (though I don’t know which one), abruptly release the clutch pedal and press the gas - the car slightly rears up and starts with a noise! To be honest, I don't even know how to describe emotions. This is something incredible! There is very little snow, there are no special obstacles, but from riding this "monster" you just want to scream with delight! A very unusual feeling. The engine is roaring, the tracks are pounding, the heart is bursting out of my chest - this is the most emotional test drive of my career! Words cannot describe how cool it is to ride this self-made caterpillar.

To turn, you need to put a lot of effort on the levers. But the maneuverability is not bad: we squeeze the "gas" to the floor, pull the left lever with all our might with both hands - the all-terrain vehicle starts to turn the "dimes" in place! Moreover, homemade tracks do not fall off the rollers - the strength of the structure is felt.

Immediately I remember the famous obscene video about a warrant officer and tankers: "Once, with a turn, turned on the front - and went!"

Off-road performance? Ground clearance- 380 mm, no overhangs, but there are tracks. It is a pity, for some reason there was very little snow in Molodechno - it was not possible to check how the car drives through deep snow. But again, there is enough emotion without off-road obstacles. You just go - and your eyes are already on your forehead!

But we drove along the ditch - the all-terrain vehicle passes through it very well. But so far Yuri has no idea when the car will start to fall back. Therefore, they did not take large slides - the driver is simply afraid to turn the all-terrain vehicle over.

In theory, everything should be fine - the center of gravity is low. But in practice, you need to make a frame, belts - and even then try to feel the stability limit of the all-terrain vehicle. There is a feeling that he is capable of a lot, but so far it is simply scary to break him - so much work has been invested in the technique.

Finally, we still try to feel this edge again, but on the rise, the connection between the rollers and the engine is unexpectedly lost! The all-terrain vehicle rolls back - and remains on the ice, which is covered with cracks along the edges. An attempt to turn on the gear and move away does not lead to anything. Only the grinding of metal is heard - the car does not drive. Have sailed!

It turned out that the cardan had torn. Moreover, he broke on the first test. However, you shouldn't even worry about it - Yuri already has a solution to the problem. Next cardan shaft will be so strong that it will withstand everything.

It's ok when u new technology something goes wrong. So far, only one has been found at the all-terrain vehicle weakness, there are no other "snot". And this is very good! The machine was built from scratch by one person, has not yet been tested - and only the drive breaks down. In the evening of the same day, the designer repaired the all-terrain vehicle and drove out of the ditch.

As a result - a complete delight. You are simply amazed at the talent of Yuri Pidgaetsky, who made such a car from scrap materials! He had some spare parts, he had to buy something - in the end, he spent about $ 800 on the construction. For this money, you can't even buy a frail ATV, but here you get a whole "monster" - an all-terrain vehicle on a caterpillar track. Bravo to its creator!

Many lovers of home-made vehicles are engaged in the development and manufacture of tracked all-terrain vehicles.

A variety of solutions are used when bringing ideas to life, but the biggest problem for enthusiasts of this type of transport has been and remains the caterpillar. Of course, no one forbids the use of factory-made propellers in their samples, but I want an all-terrain vehicle (or snowmobile), made with my own hands, to have home-made caterpillars. Let's take a look at some of the ways to make tracks that have shown reasonably good performance.

The simplest option

The caterpillar propeller for snowmobiles and light all-terrain vehicles can be made on the basis of an ordinary bush-roller chain and a conveyor belt. To manufacture such a caterpillar, there is no need to have special tools or equipment, everything is done “on the knee”.

Caterpillar from the conveyor belt

To extend the life of the tape, it is advisable to stitch its edges with a fishing line with a step of about a centimeter (just like seamstresses do overcasting the edges of a fabric), this will save the tape from fraying. The connection of the tape into a ring can be done in any available way, for example, using a hinge like a piano loop, or stitching the ends of the tape (less reliable method).

The thickness of the tape should be selected based on the engine power. When using engines from motorcycles of domestic production, nice results shows a belt with a thickness of 8 to 10 millimeters, which is used on agricultural conveyors.

Despite the simplicity of manufacture, such a self-made track for a snowmobile has a decent resource and, moreover, is easy to repair if necessary.

Tire tracks

It is quite common among home-builders to make caterpillars from car tires... For this purpose, tires are selected from trucks, preferably with a suitable tread pattern (there will be less work with the tire in the future).

Tire caterpillar

To make such a caterpillar, it is necessary to cut the beads from the tire, leaving only the treadmill. This work is quite laborious and requires a lot of patience, since only a well-sharpened boot knife is used from the tools.

To simplify the work, you can wet the blade from time to time in a soapy solution, then the rubber is easier to cut. Alternatively, you can consider the use of homemade gadgets for cutting, or use a jigsaw on which a file with a fine tooth is fixed (it is also better to moisten the file with soapy water).

First, the sides are cut off from the tire, then, if necessary, excess layers are removed from the seamy side of the resulting ring (if the track is too hard). After that, if the tread pattern does not meet the designer's requirements, a new lug structure is cut.

A home-made caterpillar made of a tire has an undoubted advantage over the above-described sample, since it has an initially closed loop, which means that its reliability will be several times higher. The downside is the limited width of the finished track, however, if necessary, you can use a double and triple width option.

Belt tracks

Attractive because of its relative simplicity, the option of making a caterpillar with your own hands.

V-shaped belts are joined together by means of lugs attached to the belts with rivets or screws.

Thus, a track is obtained with already existing holes for the drive sprocket (for this you only need to leave gaps between the belts).

There are many ways to make caterpillars - the main thing is to have the desire and patience, and then everything will work out.

The topic of off-road transport has always been a success among home-builders. Homemade all-terrain vehicles appear in all corners of our country, and it is very difficult to find two identical vehicles (most likely, it is simply impossible). I would like to present to your attention a small overview of all-terrain vehicles built by craftsmen by homemade craftsmen, and analyze the main points of designing such samples.

The most popular all-terrain vehicle designs are two: low-pressure pneumatic vehicles and tracked all-terrain vehicles. Let's briefly dwell on each of them.

Pneumatic passages

This category homemade all-terrain vehicles appeared in the 60s of the last century with the manufacture of the first homemade products of a rather original design. These were vehicles with a tricycle layout, but instead of front wheel a ski was installed on them. This scheme has survived to this day, although now it is used much less often.

Homemade all-terrain vehicle from a motorcycle

These days, schemes with the number of wheels from three to six are popular (schemes 3x2, 4x4, 6x6).

Tracked vehicles

The scheme of an all-terrain vehicle on tracks has many adherents among DIYers. All-terrain vehicles built on this principle are structurally more complicated than wheeled vehicles, respectively, the costs of their manufacture are higher, but in operation they are somewhat superior to pneumatics.

Homemade tracked all-terrain vehicle

In general, of course, it is illogical to compare these two classes of all-terrain vehicles, because in each specific situation one or another scheme will have superiority (in my opinion).

How do homemade all-terrain vehicles begin with your own hands?

Before taking on the creation of an all-terrain vehicle, an amateur designer must find out for himself the purpose future car... At this stage, the estimated number of places, the mass of the payload, the season and operating conditions are specified.

After the answers to the above questions are received, you can decide on the concept of the future self-propelled vehicle. Only having understood the general idea for oneself, one should proceed to the issue of choosing the elements of the all-terrain vehicle.

At this stage, the type and model of the engine, the composition of the transmission, the design and type of the frame, the cab equipment and other elements are determined. The greatest attention should be paid to the choice of the formula running system if it is a caterpillar propeller - then which one, if the wheels - how many, how many of them are driving and how many steered wheels.

After analyzing desires and possibilities, it is done final choice in favor of this or that all-terrain vehicle scheme. This is how homemade all-terrain vehicles are designed, and drawings are a mandatory stage in this activity.

Engines for homemade all-terrain vehicles

Often, the lack of sufficient funds imposes restrictions on the choice of the engine, so the whole choice comes down to the formula “what is at hand”. And at hand, as a rule, there are two- and four-stroke motorcycle engines, less often there are old automobile power plants.

If the situation with free money allows you to choose an engine without thinking about its price, then we can recommend the following options:

• For all-terrain vehicles on pneumatics, it is preferable to use motorcycle engines, while trying to choose the most suitable motor in terms of power and operating conditions. It will be very good if the motor has a system forced cooling(air or water), as there are no conditions for normal free cooling on the all-terrain vehicle.
• Four-stroke motors have a number of advantages over their two-stroke counterparts, so it is recommended to pay attention to them. An example is boxer engines from Irbit heavy motorcycles.
• Automotive motors are well suited for installation on homemade ATVs on tracks. These motors provide sufficient torque, are reliable in operation and have an acceptable price / performance ratio. The choice of the type of engine, diesel or carburetor, is up to the designer. Both schemes have their pros and cons. So, for example, diesel is more economical than Gas engine, but not the fact that in severe frost conditions it will be easy to ensure its stable start and operation without using additional equipment (preheater). (Although this also applies to gasoline engines, but to a lesser extent)

All-terrain propellers

Wheels for all-terrain vehicles on pneumatics are made by craftsmen according to four basic principles:

• 2 discs made of sheet metal with bridges between them are attached to the sleeve, then the camera is put on and fixed with sections of the conveyor belt. Additionally, a protector from another camera can be worn on top of the camera.
• One disk is fixed on the sleeve, jumpers are attached to it, and side rings are welded or riveted to the jumpers.
• The scheme is similar to the previous one, but the role of the central disk is played by sheet metal or pipe spokes.
• Two discs are mounted on the hub, like the discs of a wheel from a scooter (split wheel).

Homemade tracked all-terrain vehicles can use tracks from industrial designs of snowmobiles and all-terrain vehicles (for example, the Buran snowmobile), or move on homemade tracks.

Homemade caterpillars

In the overwhelming majority, a self-made caterpillar is a piece of conveyor belt on which the lugs are fixed and holes are cut for the teeth of the drive sprocket. There are also more advanced track designs, for example, with tracks cast in a home workshop. But this is a very time consuming task.

In conclusion, I would like to dwell on one very interesting specimen for those who do not need a full-size all-terrain vehicle, but need to move off-road. For example, go to passenger car to the hunting lodge, take this miracle out of the trunk and go hunting. Probably, it is worth taking a closer look at this crumb and taking note of the original technical solutions incorporated in it. How do you think?

Many residents of northern latitudes and places with poor traffic are engaged in the development and assembly of various equipment with increased traffic. Tracked all-terrain vehicles are no exception. There are many different options creating a similar technique. But the most problematic issue for ATV designers is the manufacture of tracks.

You can, of course, use their factory production, but having completely assembled an all-terrain vehicle with your own hands, you also want to have tracks of your own production. Today, there are several options for creating such propellers, which practically do not differ in their technical characteristics from the factory.

Simple track variant

The simplest version and snowmobiles, is made from a conventional roller-sleeve chain and a conveyor belt. Moreover, its production does not require any special equipment and tools. In this case, the work can be done almost in the middle of the living room.

In order for the conveyor belt to serve for a long time, it is necessary to sheathe its edges with fishing line with a distance between the stitches of about one centimeter. This activity is very similar to sewing a fabric with a seamstress. In any case, this stitching will prevent the ribbon from unraveling while driving. You can fasten the ends together in any suitable way. For this, it may be suitable swivel joint, resembling a piano loop, or simply sewn, but it is unlikely to last long.

The thickness of the conveyor belt depends on the power of the power unit. If an engine from a Soviet-made motorcycle is installed in an all-terrain vehicle, then a 0.8 - 1 cm thick tape used on conveyors in agriculture... To stiffen the track, it is necessary to attach a sleeve-roller chain at its inner part. This can be done using bolts or stiff steel wire. The main thing is that the chain fits snugly in the surface of the conveyor belt.

Tracks made in this way are distinguished by their long-term operation, although they are easy to manufacture. In addition, repairs can be easily carried out if necessary, even in the field.

Tire propellers

Many owners of snowmobiles use ordinary tires from a car as tracks for their equipment. For these purposes, tires from trucks are needed, while it is worth choosing them with the required pattern, so as not to complicate your work in the future.

To make a caterpillar drive from a tire, it is necessary to cut off the sides from it, leaving only the part with the tread. This event takes a lot of effort and requires patience, since only a well-sharpened boot knife is needed to work.

In order to slightly simplify the manufacture, it is necessary to periodically wet the knife with soapy water, which will facilitate the process of cutting the rubber. Some people use specially designed devices for these purposes. You can also use an electric jigsaw with a fine-toothed file attached to it. It also needs to be watered with soapy water.

The first step is to cut the beads from the tire. Further, if necessary, it is required to remove several inner layers in the resulting caterpillar. This is done to give it softness. If the tread pattern does not suit you, then you should start cutting a new one, which is quite a painstaking task.

This type of tracked lug has one distinct advantage over the previous version. Since it is one-piece, without connections, then its reliability is much higher. Of the negative points, a small track width can be noted, but to increase it, two or three tires can be spliced.

Belt tracks

The simplicity of the manufacture of such tracked propellers is increasingly attracting the owners of all-terrain vehicles to use them on their equipment. Belts with a wedge-shaped profile are assembled into a single structure using lugs, which are riveted or screwed to the belts.

As a result, it turns out that the track blade already has holes for the sprocket. To do this, the belts must be stacked at close intervals.

Making a caterpillar for an all-terrain vehicle

The name of the all-terrain vehicle is understood vehicle with increased cross-country ability. These include tractors, snowmobiles, SUVs and tanks. Since it is often from improvised vehicles. Often, motorcycles or scooters are used for this, but the end result is a vehicle that is not afraid of either off-road or dirt. Increased cross-country ability The all-terrain vehicle is mainly dependent on its tracked propellers, which are put on the wheels.

In this version, the caterpillar will have four stripes of 5 centimeters wide. They must be cut from a conventional conveyor belt. Then make the connection with the lateral sides using a profile in the shape of the letter P. Next, you need to make the balancers. Using a stamp, you need to make parts into the floor of the wheel from sheet steel. After that, it is necessary to make the hubs from bronze. The half wheels should be connected with six bolts. The balancers are made.

The next step will be the production of shafts for the track support drums. Holes for bearings should be made in them. Drums can be made from duralumin blanks. Connecting them together, you must insert a rubber sprocket. It turns out that the caterpillar is driven by a drive sprocket with a chain drive. It is installed on the rear fork.
After that, you should collect the entire caterpillar into a single whole.

The vertical bow must be fitted with a steel bushing through which the wheel axle passes. A mechanism is attached to the lug on this bushing, which fixes the structure of the rear fork. Track balancers are attached to the remaining ears of the all-terrain vehicle. The propulsion unit is ready for use.

As you can see, you can make a caterpillar different ways, the main thing is to have patience and desire.
