How to make a homemade snowmobile on caterpillars. How to make a snowmobile on the caterpillars with your own hands? Homemade mini snowmobiles on a caterpillar

In the northern regions of our country, one of the most sought-after means of movement is snowmobile. Considering the fact that the cost of most modern models is high enough, much more economical to assemble this device. It is only necessary to adhere to the mixture, the necessary tools and find free time.

To implement the idea, you will need an ordinary motoblock. In winter, this device is installed on the national snowmobile structure, and in the spring it is removed and used for its intended purpose.

Snowmobile - a specialized vehicle designed to ride in the snow. There are many different modifications, each of which varies with its technical characteristics and capabilities. Distinguish models:

In addition, various engines (on air or water cooling) and transmissions can be installed. Contrary to differences, all models unites one common fact - they are universal means for movement in the snow and Nasta. Thanks to specific technical specifications, in winter, snowmobiles have several advantages over other devices:

1. Efficiency. Snowmobiles use much less fuel than other vehicles.
2. Speed. If you take into account the fact that cars, by virtue of their weight and construction, are often stuck in deep snow, snowmobiles are much faster than snow-covered sections.
3. Maneuverability. Due to its small dimensions, snowmobiles can easily move even in winter forest conditions (which is very useful for people who are fond of hunting);

The sphere of application of these vehicles is very wide - rescue work, winter hunting or fishing, tourism, travel - this is not a complete list of cases where they are necessity.

Similar "" use everywhere where there is snow cover. And conventionally divide on serial and self-made.

All that is needed for creation - caterpillars, steering wheel, use and engine. No more, no less.

How to collect snowmobile on caterpillars

Snowmobile development begins with creating a drawing or sketch. To do this, use both their own author's visions and ready-made sketches, in abundance presented on the Internet. In any case, it is necessary to provide for the presence of the lead and driven part. The leading part consists of a drive, frame and power unit, led by - from the poloz, the steering wheel and shock absorbers.

Frame

First of all, it is necessary to collect a frame. For this purpose, conventional pipes with a small diameter (folk crafts are advised to give preference to motorcycle frame structures). To give it the necessary form, you need to use the welding machine.

Initially, the fastening of parts occurs with point welding - this is necessary in order to not destroy the collected design in case of errors in case of errors. After the frame is ready, it must be welded with a continuous seam.

Force aggregate

The engine is a regular fiberboard. In addition, it is necessary to create a drive that can lead in traffic of the caterpillar. As a rule, an ordinary chain drive is used, which is suitable directly to the leading shaft. At the same time, the snowmobile is obtained by a maneuverable and light, significantly increases the thrust force and stability of the entire device.

To create a conventional motorcycle chain, tracked leading shaft and two stars. Collect the drive is not more difficult than dining a chain on a bike. A larger asterisk is installed on the shaft of the power unit, a smaller caterpillar is dressed on the driving axis, after which the chain is tensioning between them. And that's all that is necessary to create a full and fairly powerful drive.

Caterpiles

Caterpillars are made independently - this does not represent any difficulty even for a newcomer technique. An ordinary rubberized or transport tape is taken, which is installed in soils. The soils (trackers) are transverse rails that are fixed at equal intervals along the entire length of the tape for the "lamination" of snow. Tracts can be made of durable plastics or, for greater reliability, from a thick sheet of tin.

Treads are attached with bolts. When mounting the soils, you need to take into account the same distance between them, otherwise the caterpillar will slip on the surface of the snow and stop. When choosing a transport tape, it is important to take into account its width in relation to the sizes of the device - the more the technique, the wider tape. All nuances look in the video below.

Stoles must have the optimal characteristics of sliding in the snow and / or ice. From the available materials you can use shockproof plastic or metal. It is recommended to use wide bands, which will provide a large contact surface with a coating and, therefore, a higher speed.

Snowmobile assembly is made in several simple stages:

The roller shows the design of one of the homemade snowmobiles called "Snigar".

In addition to caterpillar snowmobiles, folk craftsmen Mastery Wheels:

Remembering the history of creating a homemade snowmobile, realized how long my passion for the design of technology began. Another youth (and now I am already a pensioner) received a specialty for a mechanic and mastered my own welding case, other specialty metalworking. But the knowledge of the design, to tell the truth, "boast" could not, and indeed learn. He built on the host of all sorts of "diamonds" on wheels and caterpillars: went on them and off-road, and in the snow, but no reliability, no beauty in them.

But at the beginning of 1988, "model director" came out, in which there was an article about a snowmobile "Caterpillar around Ski". That's where it began!

We have such a place that snowproof lies for half a year and even more! Local roads are clean, as a rule, not on time, and so that only an all-terward truck can pass. Well, there is nothing about parcels. In addition, I had hobbies: hunting and fishing. That's all this and came to make a good sweaty snowmobile.

Built for myself, helped friends, native, gained experience. Constantly improved the design "According to the Evolution laws": replaced heavily - on a slight, unreliable - on a strong, introduced suspension: Spring, spring, shock absorbers. Total built more than a dozen snowmobiles: on caterpillars with wooden and polyethylene cams around Ski bipiz; rubber with rollers block; and with one control ski, and with two.

story will be negotiated about the last sink. I can not say that it does not have drawbacks, but in his design I invested all the accumulated experience and the car turned out, it seems that, successful, although without excesses (or, as they say, is utilitarian), but it looks good, and reliability on height.

The snowmobile layout is chosen the most common, both on similar domestic machines and on foreign: two front controlled skis; Power unit, located in front of the hood; Next - a caterpillar block, and over it the seat and behind - the trunk. The total snowmobile length is 2300 mm, the width of the outer edges of the ski of 900 mm, height before the steering wheel - 1000 mm, to the seat - 700 mm.

Under the hood:

Power unit (engine, clutch and transmission box in one block) - Tula 200m manufactured by TMZ (Tula Machine-Building Plant). He was put on any motorcycle produced in Tula: scooters (including in the cargo "ant), motorcycles, etc. The unit is quite reliable, although it is heavy.

The power of the new motor was 11 hp. With the number of revolutions up to 3600 per minute. But he is already not one ten years old. However, the forces are eight-nine, according to my feelings, it is still preserved in it. The engine of 196 cm with a working volume of 196 cm3, two-stroke and operates on a mixture of low-octane gasoline with engine oil (type "Autol") in a ratio of 10: 1.

The cylinder is equipped with regular coercive air cooled.

The gearbox has a gear ratio of 2.353.

To transmit rotation from the secondary (output) shaft on the helmet of the drive shaft, it was necessary to make a welded extension from the pipe with slot tips. At one end, the inner slots are cut directly in the pipe (to attach the extension to the shaft). On the other - the outer slots for the adapter, the landing space for the bearing and the thread M20x1.5 for fastening the stars on the extension, are made on a welded tip.

Looking forward, I note that exactly the same tip is welded to the drive shaft of the caterpillar, which is made of the stretch rear axle of the Caterpillage from the snowmobile "Buran".

Snowmobile frame - spatial, cooked from steel pipes of rectangular, square and round sections.

The base of the frame is two paired tubular spars - upper and lower. The top spar of each pair is made of a pipe with a cross section of 20 × 20 mm. Of the same pipes and most of the auxiliary elements: intermediate crossbars, sores and even the rear frame of the luggage site. Lower spars - from the pipe with a cross section of 28 × 25 mm - this is the thick pipe in the frame design. From the same pipe, front traverse, front crossbars and consoles, the upward ridge.

It must be said that the pipes frame - the cross section of a small and not even fat-walled. Therefore, in places where the holes drilled, the bushings inserted in them and welded in a circle.

The add-in frame (rack, arc) is made of a round tube with a diameter of 20 mm - from old chairs, thin-walled, but strong enough. But it was difficult to weld them, but if it is done with a semi-automatic apparatus, the process is much easier. The trunk frame under the seat, as well as the framework of the median part of the site, from the equal 15-mm corner. Between these frames, I lay down long-term things, such as skiing. The steering column - from the pipe with a diameter of 32 mm - built into the front of the superstructure. Swivel pivot sleeves are cut from cycling and welded traverses. In the frame are also integrated (welded to the rear ends of the lower spars) brackets of caterpillar tension knots. The same brackets serve also in places of attachment to the frame of the bearings of the balancing shaft of the caterpillars. In addition, numerous ears are welded to frame elements, eyelashes for the installation of a power unit, fuel tank, seats, shock absorbers, etc.

1 - extension cord; 2 - Tip for the nozzle on the shaft; 3 - Tip for the drive gear

1 - caterpillar; 2 - drive gear wheel caterpillar (2 pcs.); 3 - a node of the drive shaft of the caterpillars; 4 - springs (2 pcs.); 5 - Balance Block Bracket (2 pcs.); 6 - Tension axle pendulum lever (2 pcs.); 7 - tension gear wheel caterpillar (2 pcs.); 8 - reference roller (10 pcs.); 9 - extreme trolley (2 pcs.); 10 - middle trolley; 11 - axis of the balancing unit; 12 - supporting rink (2 pcs.); 13 - housing with the bearing axis of the balance block (2 pcs.); 14 - Spring mount bracket to the axis of the balancing unit (2 pcs.)

The tracked block (more precisely is its longitudinal half) borrowed from the old industrial snowmobile "Buran". Why half? Yes, because, first of all, is easier. Secondly, the costs and easier design. Well, thirdly, it was assumed to ride not in a snowy virgin, but in the footsteps of "pioneers".

However, in combination with a couple of fairly wide ski, the snowmobile confidently overcomes deep drifts, and freshly fallen "muffles".

The extreme trolleys are redesigned - the springs are removed, and the bushings are cooked with each other, as the carts balance themselves, sitting on their axis at the ends of the springs.

Transferred and caterpillar tension knot. The front ends of its pendulum levers are sitting on a common axis with a spring balancing knot, and the rear is suspended on homemade spring shock absorbers to the frame.

Snowmobile propulsion - a rubber caterpillar width of 380 mm (on "Buran" there are two of these). The drive of the caterpillar is carried out from the drive shaft through a pair of 9-teeth "Buranovsky" of the heading wheels. Drive shaft - tubular. As noted earlier, it is made from the back tracked "Buranovskaya" axis, installed in 80205 bearings, the housings of which are attached directly to the upper frames of the frame. The caterpillar tension is carried out by a tensioning axis with gear wheels (the same as driven) after a couple of pendulum levers planned on the axis of the balancing trolley (moving its bearings along the frames of the frame). The caterpillar stretch shaft (or rather - the axis, since this item does not transmit torque) with gear wheels, too, "Buranovsky". The contact of the caterpillars with an expensive length - a little more than a meter.

Previously, the drivers built with a reference skillet. They are good on the "Pukhl" snow and snowdrifts, but very sensitive to solid irregularities of the road. From them - not only is transmitted to the driver discomfort, but there are breakdowns of the tracks and even the Scolation itself. Therefore, this time I decided to make a propeller with a rubber caterpillar and support rollers, as it assumed to ride the rolled snow and even ice.

Snowmobile transmission, which is called, it does not happen easier, although not without raisins. It consists of a single-stage chain transmission from the "IZH" motorcycle in 15.875 mm with a pair of stars: the presenter has 15 teeth, driven - 21, that is, the gear ratio is 1.6. The secondary (output) shaft of the power unit is lengthened by the pipe with the inner slots on the shaft on the shaft and the slot tip on the other. The free end of the extension agent is installed in the 80205 bearing, the housing of which is fixed on the M-shaped bracket, welded to the frame. On this tip through the adapter with the internal and external slots put the leading chain transmission starf. The driven star is planted (also through the slotted adapter) on the slotted tip of the drive shaft of the caterpillars. Adapters made from gear: calved, focused, spinned. Thanks to the slotted adapters of the stars (and, consequently, the gear ratio) is easy to change even in the field conditions under road conditions (more precisely, the density and depth of the snow cover).

Snowmobile controlled skiing - homemade, 900 mm long (blank - 1000 mm) and 200 mm width. Made of steel sheet 2 mm thick. Stamped pollows: in the middle - triangular groove, and along the edges - grain-grains, underground bent up (contact surface with snow - 800 mm). The longitudinal ribs of the stiffness of the P-shaped section were welded from above, and the ears and eyeles for fastening the suspension knots are welded, and there are ahead of the 3-mm rod ahead.

Each ski has a suspension consisting of a shock absorber (from the "Tula" motorol) and the self-made lever from the square of the square section 20 × 20 mm.

Steering - mixed type. The steering wheel itself is a motorcycle lever, and the rest is like a car. The steering shaft is a "turning" with a cardan hinge and even a kind of steering mechanism. "The turning point" did it because he did not enter the "parallel" with a pivot sleeve (and in general, straight shaft is better). It should be noted that the lower end of the shaft structurally turned out to be ahead of the swivel levers and the tag, and the sump is directed backwards. With this position, when turning the right, the steering wheel was needed to turn left, and vice versa, which contradicted common sense. Therefore, I had to enter the steering mechanism, which serves to coordinate the rotation of the steering wheel and the direction of skis. The mechanism is a pair of identical gear in the case. The leading gear by means of a slotted connection is attached to the end of the steering shaft, and the shaft of the driven gear is connected (welded, although this node is expedient and it is not difficult to make it too collapsible) with a T-shaped compound. From the bump through the steering thrust and swivel fists, the ski turn is simultaneously turning into the same direction, which steering wheel rotate.

Equipment. The fuel tank is welded from two tanks from the mopeda "Riga".

The seat - from the Minsk motorcycle is mounted on racks with a dryluminous sheet. Under the seat is a tool box, and between the drawer and the floor - a free niche with a hole behind. She lay in her if necessary for skiing, shovel and other long items. The hood is the redesigned front of the stroller (side trailer) of the Java-350 motorcycle. Electrical equipment regular. Headlight - from the Minsk motorcycle.

Sanki trailer - homemade. I believe that it is better to have small sledges than a big trunk on a snowmobile: if somewhere stuck, then sledges can be chopped up, the way to protruding and attach again. The body was once a hull of the side trailer of the Motorcycle "Java-350", or rather what remained from him after the manufacture of the hood for the snowmobile itself. His rooted, cutting around 200 mm in the middle. Then I slag the front and rear parts with exhaust ripples. Under the body posted a few cross-line from the pipe of a rectangular section of 40 × 20 mm, one of the wide walls of which left as the ears at both ends. The ears attached to the sidewalls of the body with exhaust ripples.

The body is mounted on skis from aluminum panels of the electrocontruction by means of tubular squares of a square section 20 × 20 mm. Racks at the top are welded to crossbars with ears and below - to "heels" - steel square plates with a thickness of 2 mm. "Heels" rushed to the clam of skis all the same exhaust ripples.

I want to note that the drawings of the nodes are working, and familiarizes: some are not all sizes (for example, frames), somewhere can not coincide, as the drawings were made on the finished design.

But in general, I believe that the manufacture of the design according to the drawings is already production, and not creativity.

V.Sirnov, P. Syava, Nizhny Novgorod region.

In the regions with large snowfall in winter, it is impractical to use two-wheeled vehicles. But the car is not always needed. In such cases, a snowmobile comes to the rescue, but this type of transport is expensive. If you wish, you can make a snowmobile with your own hands, and the ways how to do it, a lot.

How to make a snowmobile

You can make a snowmobile from different vehicles that stand in the garage.

From motorcycle

You can make a snowmobile from a motorcycle using different models for this. The most popular are IL and Urals. The advantages of such alterations are that it is not necessary to make special changes. With good maintenance, the funds can be left even a native frame.

Alteration technology:

1. Metal pipes or appropriate corners make a rectangular frame. Its optimal dimensions - 150 * 43.5 cm.
2. In addition to the IL motorcycle, it is necessary to make a steering beam. Made it from metal corners. Optimal dimensions - 50 * 50 * 5 mm. Additionally, the beam is cured with metal linings.
3. After that, it can be installed on the drilling machine horizontally. Process the connection location. In the same way to do with the frame. In these places you need to make special grooves for reliable fixation. Additionally to the front frame to attach the corner.
4. Now you can secure the seat for motorcyclists.
5. You need to make holes in the spars.
6. Between the front and middle part of the frame, you must arrange a channel to strengthen the design.
7. Regardless of whether a snowmobile from the "Ural" or another motorcycle model is made, it is necessary to choose a caterpillar star and rubber tape in advance. Optimal dimensions - 220 * 30 cm with a thickness of not more than 1 cm.
8. Before installing the caterpillar, it is recommended to entee a chipboard, which will allow the material not to be separated during operation.
9. Now you can go to the transmission. It consists of two parts. The first - front axle, is the lead. It is made of tubular shaft, caterpillar stars and rink. Second - rear axle. It is made of a caterpillar drum and a tubular shaft.
10. Finish the process of making a snowmobile is needed by welding ski from sheet metal.

When the motorcycle is reworked in a snowmobile, it is important not to change the steering system. In the final product, this part must perform its initial functions.

The principles of alteration are the same, they do not depend on the model of transport. But the snowmobile from the Ural motorcycle will be heavier.

From Zhiguli.

The design of the car is characterized by simplicity, ease of control and high maneuverability. For manufacture, you need to follow the instructions:

1. Assembling frame. It is better to make it from the pipes. A frame of anterior and central beams (steel pipes with a diameter of 5 cm), two lower diagonal elements (bent pipes with a diameter of 3 cm) and the rear pan. For fixing elements use welding.
2. Installing steering columns. To do this, you need two sleeves on the front beam.
3. Fixing semi-axes. It is located on the rear frame, it is pre-welded the body for it. It is made of a metal pipe with a diameter of 6 cm. Fix the semi-axes with the help of sleeves and electrostaslary.
4. Installing the engine from the car. Previously, you need to make the front and rear fasteners on the central beam. First, they need to be located on the engine itself, but only then welcome to the frame.
5. In a homemade snowmobile, you can set the wheels of a large diameter or skis from the metal sheet. In the first case, the rear and front wheels need to pairwise connect the metal pipe. At the same time, in the hub, make a groove under bearings, which subsequently fix the spring rings. Additionally, set the spacer bushing between the bearings.
6. On each wheel, install an asterisk depending on the expected maximum speed. Such a snowmobile can be used at any time of the year. For the snowy winter, the design is suitable in which the front wheels are replaced by skiing.
7. Installing the steering system. It is taken by a solid car, for example, from Zaporozhets, or a motorcycle. The choice depends on personal preferences. In the first case, gas, clutch and brake pedals are additionally installed. Transmission control is performed using a lever and tight thrust.
8. Installing a snowmobile cabin, whose role is performed by car body.

Figure 1. Small snowmobile scheme

The primer attached to the conveyor belt with two furniture bolts 6 mm with a large semicircular hat. In the manufacture of the caterpillars it is very important to withstand the same distance between the soils, otherwise they will "dial" the leading stars and the caterpillar will begin to slip and slide from the rinks.

Figure 2. Fixture of cutting of plastic pipes:
1. Wooden bar;
2. Plastic pipe;
3. Metal corner.

For drilling in the conveyor belt holes under the fastening bolts 6 mm made a conductor. The holes in the ribbon drilled the drill on a tree with a special sharpening.

Using such a conductor, 6 holes can be drilled in the conveyor tape at once for the attachment of the three cargoes of the caterpillar.

In the store I purchased four inflatable rubber wheels from the garden trolley, two leading stars from the snowmobile "Buran" and two closed bearing №205 for the leading shaft of the caterpillars.

Make the drive shaft of the caterpillar and bearings for bearings I asked Tokary. The snowmobile frame made himself from square pipes 25 × 25 mm.

Since the axis of the turns of the turn of the skis and the steering wheel are on the same line and in the same plane, you can use a continuous steering craving without ball lugs.

Ski rotation bushings are made easy. For the front transverse frame of the frame, I welded water clutches with an internal thread 3/4 inches. They screwed up the nozzles with an outdoor thread, which was attached to the welding of the tower steering thrust and ski racks.

I recommend using skis from the children's snow scooter "Argomak". They are easier and more elastic, but they need to install corners for fastening to the rotting rack of the snowmobile and the metal sub-cut - for better snowmobile control when driving in an imagination or rolled snow.

Adjusting the tension of the chain takes place due to the engine offset.

Snowmobile control is very simple. With increasing engine speed, the gas handle, located on the steering wheel, the automatic centrifugal clutch is turned on and the snowmobile starts movement. Since the estimated snowmobile speed is small (only about 10-15 km / h) and depends on the density of snow, the snowmobile brakes are not equipped. It is enough to reduce the engine turnover and the snowmobile stops.

I will share a few tips, which when repetition of this design may be useful

1. The pipe for the tracks I cut along the manual circular saw on the tree first on the one hand, then on the other. So it turns out to be even than to immediately cut both walls. More convenient to handle small blanks. If you immediately cut along a long tube, then in this case the plastic will melt and the saw disk will climb.

2. Caterpillars can make any width. And each constructor has the right to choose what is more convenient for it: make a wide, but short caterpillar or narrow and long. Just remember that with a big caterpillar, a snowmobile will be poorly controlled and the engine loads more, and with a small in a loose deep snow he may fall.

3. On some of my photos, it can be seen that plastic "barrels" are installed inside the caterpillar. These are the guides of the stops for the Scolation, which must prevent the caterpillars from the rinks. But in the process of exploitation of a snowmobile caterpillar and without Scolation did not slip from the rinks, so "barrels" can not be installed, which will reduce the mass of the snowmobile.

4. At the end of winter, I completely disassembled a snowmobile to determine its weight. The weight of his individual nodes was like this:

• caterpillar - 9 kg;
• presenter assembly - 7 kg;
• two pairs of wheels with axes - 9 kg;
• engine and steering wheel - 25 kg; pair ski -5 kg;
• rama-15 kg;
• double seats with racks - 6 kg.

Total weighs 76 kg together.

The weight of some details can be reduced. Nevertheless, the weighting rate for a snowmobile with the caterpillar of this size is quite satisfactory.

The geometric dimensions of my snowmobile are as follows: the length of the snowmobile frame - 2 m; The distance between the axes of the support wheels (rinks) is 107 cm; The width of the caterpillars - 47 cm. The step of the carriage of the caterpillar depends on the thickness of the transport ribbon and it is necessary to pick it up with an experienced way (I got 93 mm).

I do not bring the exact size and drawings of the snowmobile details, as everyone who will gather repeat the design, will focus on those details and components that can be purchased or making themselves.

In the photo, the stages of snowmobile manufacturing according to the above drawings schemes:

1. Billets of the soils of the future caterpillar.
2. Special leading stars from the snowmobile "Buran".
3. Homemade trail of caterpillars with installed stars for chains and caterpillar.
4. Conductor for drilling holes in the conveyor belt.
5. Catering rollers with axes and attachment brackets to a snowmobile frame.
6. The drive from the engine of the drive shaft of the caterpillars is carried out by a chain from a motorcycle.
7. Snowmobile frame with the leading shaft and support rollers of the caterpillar.
8. Ski rotation mechanism.
9. At this snowmobile, I put plastic skis from children's Chinese Sanok. But the plastic, from which they are made, turned out to be very fragile and by the end of winter one of the skis broke down.
10. Skiing from a snow scooter "Argomak" with a fixed line (skate) and fasteners for installation on a snowmobile.
11. Ski turn bushings. Everything is very simple: no bearings. It is only necessary to put lubricant on the thread, and the long service life is provided. In addition, screwing or turning pipes, a snowmobile clearance can be changed.
12. The axis of the front wheels (caterpillar rollers) is attached to the frame stationary, and the axis of the rear wheel rinks, rotating the bolt, can be moved to regulate the caterpillar tension.

Homemade snowmobile with their own hands: photo

Many lovers of self-made technology are engaged in the development and manufacture of all-terrain vessels on the tracked go.

A variety of solutions are applied in the embodiment of ideas in life, but the biggest problem of enthusiasts of this type of transport was and remain caterpillars. Of course, no one forbids the use of factory manufacturers in its samples, but you want the all-terrain vehicle (or snowmobile), made by their own hands, had homemade caterpillars. Let's look at some ways of making caterpillars that showed sufficiently good performance characteristics.

The simplest option

A tracked propulsion for snowmobiles and lungs of all-terrain vehicles can be made on the basis of an ordinary sleeve - roller chain and conveyor belt. For the manufacture of such a caterpillar, there is no need to have special tools or snap, everything is done "on the knee."

Transport Tape Caterpillar

To extend the life of the tape, it is desirable to flash her edges with a fishing line in a step of near a centimeter (just as the seamstress makes the edges of the fabric), it will save the ribbon from grinding. The tape connection in the ring can be performed in any available way, for example, use a hinge by the type of piano loop, or sew tape ends (less reliable method).

Tape thickness should be selected based on the engine power. When using engines from motorcycles of domestic production, good results show a tape with a thickness of 8 - 10 millimeters, which is used on agricultural conveyors.

Despite the simplicity of manufacture, such a self-made caterpillar for a snowmobile has a decent resource and besides, it is easily repaired if necessary.

Tire caterpillars

Pretty common among homemade producing caterpillars from automotive tires. Tires from trucks are selected for this purpose, preferably with a suitable tread pattern (there will be less than working with the bus in the future).

Tryska caterpillar

For the manufacture of such a caterpillar, it is necessary to cut from the tire of the side, leaving only a treadmill. This work is quite laborious and requires a lot of patience, since only a well-sharpened shoe knife is applied from the tools.

To simplify the work, you can make the blade in the soap solution from time to time, then the rubber is easier cut. Alternatively, it is possible to consider the use of homemade cutting devices, or use the electric bike, on which the pink with a small tooth is fixed (the pylon is also better to make soapy water).

First, the boards are cut off from the tire, then if necessary, the extra layers from the wrong side of the received ring are removed (if the track is too solid). After that, if the tread pattern does not satisfy the requirements of the designer, the new structure of the soils is cut.

The homemade trailer caterpillar has a certain advantage over the above sample, as it has an initially closed loop, and therefore reliability it will be several times higher. The disadvantage is the limited width of the finished caterpillars, but if necessary, you can use a dual and width version.

Caterpillars from belts

Attractive because of its relative simplicity, the option of making caterpillars with their own hands.

The belts with a wedge-shaped profile are connected to a single integer with the help of bribes attached to belts using rivets or screws.

Thus, a caterpillar cloth with already existing holes under the leading asterisk (for this it will be necessary only to leave the gaps between the belts).

Many ways are making a lot - the main thing to have a desire and patience, and then everything will turn out.
