Homemade snowmobile on caterpillars with their own hands to buy. How to make a snowmobile with your own hands - detailed instructions. Requirements for converting equipment on a crawler

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. First - front axleIs leading. 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 intended 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.

Snowmobiles sold in the store have a fairly high price and often do not fit into the budget. And moving around the snow still need. Fishing, hunting and just an active rest in the wild requires passability. Therefore, we will look at ways to make a snowmobile with your own hands.

Decided to make a snowmobile with their own hands? There would be a desire ... Of course, to create a decent vehicle Superior skills, elementary knowledge of physics, seducker, materials, spare parts and some tools will be needed. There is no doubt that all this you have, and why not, you can buy in the process of work. The main thing is what the result is! Handbook made snowmobile, moving through the snow, overcoming snow-covered off-road is cool!

Features and advantages of homemade snowmobiles

The basis of the winter vehicle design is a tracked drive and steering skiing. Of all the advantages of self-made snowmobiles in front of factory models, the following can be highlighted:

• The price of a motorcycling assembled from undergraduate materials is 5-10 times.
• Ability to assemble a model of the desired configuration, power, etc.
• Reliability of construction, thanks to the use of high-quality materials and proven mechanisms.
• The benefit from the fact that you can not buy new materials and details, but to use stored in the garage.

The homemade snowmobile is a vehicle that can be found not only in country off-road and ski resorts, but also on the streets of settlements.

Making a snowmobile in drawings

How to make a snowmobile with your own hands, what are the details and nodes? To create a homemade caterpillar caterpillage for snow in the snow, a list of necessary components is drawn up, sketches are made and drawings are performed. In the future, they will serve as a guide to create a vehicle.

Standard design consists of several elements. It includes:

• Rama, which can be borrowed from a quad bike, scooter, scooter, motorcycle, etc. If there is no such possibility, it is made by welding with thin-walled metal pipes, a diameter of 40 mm.
• Seat - preferably from moisture-repellent material.
• The engine can also be from the motorcycle, motorcycle, scooter, etc. The choice is determined by the speed and weight of the vehicle.
• The tank is a container of 10-15 liters of metal or plastic.
• Skiing on a homemade snowmobile on caterpillars can be prepared or made them of nine-ten-layer plywood, 3 mm thick.
• The steering wheel, like many other elements, is taken from the two-wheeled unit.
• The drive transmitting rotational movements from the engine to the caterpillar, which can be used a motorcycle chain.
• Caterpillar is a complex component requiring detailed consideration.

How to make the caterpillar?

Homemade caterpillars can be made of automotive tires. The advantage of using tires is that they have a closed circuit that reduces the probability of break. For the manufacture of caterpillars, the tire board is cut into a sharp shoe knife. For the remaining flexible canvas are attached primatelates, which uses plastic pipes, 5 mm thick and a diameter of 40 mm, cut along length. Halves of pipes are cut across the width of the tires, are attached to bolts every 5-7 cm.

Similarly, caterpillars made of conveyor belt. Its advantage is that in the case of its application there are no limitations in length. But there is a need for a clutch by overlapping the end of the tape with an overlap in 3-5 cm and fixed bolts. In the manufacture of caterpillars, you are often used by wedge belts. The connected by primers, they pose a full-fledged caterpillar with ready-made feces for gear.

Wide caterpillar improves the aggregate's permeability, but reduces its handling. In factory models there are three options:

• Standard - 15;
• Wide - 20;
• Overwheel - 24.

Snowmake creation sequence with their own hands

To make a snowmobile on the caterpillars with your own hands, initially need to connect the frame and the steering mechanism. Selected height and angle of inclination, then produced point weld. In accordance with the drawing, the engine is installed and recorded. It is necessary to trace so that there is no strong inclination. To avoid a large length of the fuel line, the tank is close at the carburetor.

Next is the caterpillar. The slave bridge with the web is attached behind the frame (depending on the design, on the suspension, plug, shock absorber, etc.)., The leading bridge is attached in the middle of the snowmobile (usually under the driver's seat), closer to the engine. The adhesion of the gears of bridges is predetermined. After that, the connection is carried out fuel tank, gas handle cable and brakes, the seat is mounted, other works are held.

Motoblock snowmobile with their own hands

Creating a snowmobile from a motoblock is the most popular option. A vehicle intended for agricultural worker can be used in fully or partially. It should be paid to the fact that motoblock engines are usually calculated on the weight and pressure of wheels that are less than a crawler several times. For this reason, it is better to equip a snowmobile wheels low pressure. This will help avoid fuel recalculation and premature wear details. How the motoblock is converted to the homemade snowmobile, watch the video.

In the manufacture of a snowmobile, you must listen to the advice of experienced craftsmen:

When cutting the pipes with a circular saw, it is recommended to cut one side, and then another. So you will be able to get smooth blanks. The pipe is better to be pre-cutting on the segments of the required length, since when cutting long blanks of plastic melting, and the saw disk can hold.

The size of the caterpillars can be chosen at its discretion. It can be wide and short, narrow and long, but should consider that the transportability of the vehicle will depend on its width. TS S. wide caterpillar More difficult in management, in addition, the load on the engine will increase. Caterpillar little size Will fall into deep loose snow.

Drawings of self-made snowmobiles on caterpillars present to familiarize.

Constructive schemes:
A- trap is laid in the P-shaped bottom
B-catering one, support for two skis
Wasters two, ski one
G-caterpillars in front, connecting trailer behind
D-two skis, two caterpillars

If the snowmobile has two caterpillars, then control it is built at the expense of one of the caterpillars. The maneuverability of the machine is determined by the ratio of the length of the support surface to the rut. This ratio should be equal to 1.2.

The presented model consists of two parts:
Frame
chassis and suspension

Design carcass

We will make a snowmobile frame from wooden bars and sheets of moisture-resistant plywood. We accept the thickness of the sheet ten - twelve millimeters. All the details are glued together with glue on the tree and press screws. Initially, we collect a wooden frame, in the figure marked with the letter (a), to which three parts are found (b); (IN); (D). Upon completion of the assembly, the bottom of the slip of the slip will be attached by leaf galvanized steel, 0.6 ... 0.8 mm thick. After assembly, the body is covered with hot oil and apply paintwork.

Consider drawings of self-made snowmobiles on caterpillars, typical design with an engine location in front

In many regions of Russia, the only means of movement is snowmobile. However, during the financial crisis, not everyone can afford to purchase dear technique. Why not remember the possibilities homemade designer With the Universal Motor Installation "Mind", which will make a snowmobile with their own hands.

Our snowmobile consists of two parts. The first - led by - relies on the crawling in the form of a ski with a seat for the driver. The second is the lead - consists of motor Installation "Mind" with a wheel drive. Both parts of the snowmobile are connected by a vertical hinge, which allows them to take various angular positions relative to each other.

The slave part includes a carrier frame with driver seat and control levers. It hinge reluctantly on the staples of the poloz. With a turning rack, the carrier frame is fastened hard.

Poles are a pair of wide wooden skis, parallel to interconnected. In the middle part of each skiing staples of hinged connections.

In the frame design, the attachment places of the removable foot platform equipped with brake pedals are provided.

Snowmobile control levers are connected by a single sleeve and fixed by screws under the driver seat.

Rubber tips are put on the knobs of the levers. The right handle is equipped with a cable gas adjustment mechanism from a serial motorcycle.

Steering thrust will have to make themselves. The thin-walled steel tubes with a diameter of 16 ... 18 mm are suitable. At their ends it is necessary to install connecting hinges capable of working in two angular planes.

In the second part of the snowmobile, a leading bridge with homemade wheels Low pressure. The best solution is to apply pneumocamera from cars; In the inflated state, their outer diameter is approximately 80 mm.

Produce a carrier frame (see Fig. 2) The slave of the snowmobile is best of all of the steel thin-walled pipe with a diameter of 40 mm. Bend the pipe of such a diameter without a special device is difficult, so the swivel rack of the frame in its lower part will have to be collected from two straight pieces. If there is still an opportunity to quickly bend the pipe without disturbing its cross section in the bend, we advise you to start making a slave frame from this operation.

Fig. 2. The design of the carrier frame
1 - Rotary Stand, 2 - Loose beam, 3 - arm of the axis of the levers, A - the size of the central part, b - the general view of the carrier frame.

Hacking for metal Cut the remaining tubular blanks. Connection locations will be described by a semicircular file. Put the turning rack with a curved (or welded) end on a smooth horizontal surface (concrete floor) and grab the gas or electric welding parts. Make sure that all the grateed frame parts are strictly in the same plane. To do this, stick the pipe along the entire length with the hammer. Only after this operation, connect all the details with each other.

The next step is the manufacture of flanges and plates of the support beam. One of the finished flanges will breed to the end of the support beam, observing perpendicularity to the axis of the pipe. Put two plates on the beam and breed the second flange to the opposite end, observing the alignment of the holes in both flanges. To install the reference beam on the carrier frame, grab the welding of the fold from the two sides, as shown in Figure 2.

Make sure the beam relative to the frame plane is taken perpendicular.

After that, brew a clamp. Make sure that the beam is freely moving along its axis and simultaneously rotates in the plated. By moving the beam along the axis, pick up such a position so that the distance from the planes to the flanges was the same both on the left and right. Mark this position by risks.

Now, according to Figure 2, exhibit the angle of the flange so that the loose holes look strictly down. Once again, check the position of the rice and take the welding pipe of the beam to the plated. Swipe the final adjustment and only after that the weld of the seam is completely.

To install leverage axis sleeve detailed description not required. It is much more difficult to install the brackets of the swivel axis, this work takes place extremely carefully, because here it is necessary to withstand the maximum accuracy in the alignment of the holes between themselves, as well as the location of the plane of the centers of these holes with the center of the rotary rack and the axis of the average frame segment.

The frame assembly completes the addition of welding seat brackets and stiffery brazers.

For the ski pair (see Fig. 3) you will need to make two identical struts, two identical bracket with axes and actually a pair of skis.

Fig. 3. General view of the ski pair

Fig. 4. Control details

1 - left control lever, 2 - fastening the control lever, 3 - lever sleeve, 4 - End Details of the hinge (8 pcs.), 5 - Central Details of the Hinge (4 PCS)

As for the strut, they will have to cut from a pipe segment with a diameter of 22 mm. To them, weld the corner of sheet steel with a thickness of 3 mm. The brackets will have to bend from the same steel, and the axis is to sharpen on the lathe.

Skiing is best made independently of 3-mm plywood sheets in 9 or 10 layers. The best glue is epoxy resin. Cut the drying on the mandrel with the use of powerful clamps. More information about this operation can be read in Levershem No. 12 for 1997 (article "On the snow, like on asphalt").

Levers and control thrust (see Fig. 4) are simple in design, even though the process of their manufacture will require welding and turning works. Much attention is paid to the accuracy of the execution of hinged pull. All Lufts Eliminate as an assembly.

Making a platform for legs, brake pedals and seats, we will not describe in detail - their design is understandable from Figure 5.

To connect the driven part of the snowmobile with the lead you need a rotary axis. Make it from the segment of the steel pipe with a diameter of 22 mm and a length of 140 mm. From one end, breed a square flange from sheet steel, and on the other end drill a hole for the stopper's stack. You will find the exact dimensions of the axis, the flange and the end washer on page 10 in the "Leftersha" No. 4 for 2008 - the lower part of the universal steering wheel.

By the way, from the same issue of the magazine, use the design of the leading bridge, taking it as a basis in your snowmobile, replacing only the flanges shown in Figure 6.

For the final assembly of the snowmobile, it is necessary to slightly modify the bracket by the footboard of the micromotocycle (see "Levshi" No. 9 for 2008), which is used to attach the rolted snowmobile. The improvement of the bracket is shown here in Figure 7.

For the very comfortable snowmobile, the old moped will be required, welding and some scrap metal, to create a frame of the year.

As you can see from the photo, the main alteration is the ski installation instead front wheel And the manufacture of a surcharge with a ski support.

Skiing is better to purchase ready-made, all the same skis - this is the basis of a snowmobile, but if you do not work out, then you can make yourself from Durally. Just learn, Durally ordinary welding do not boil, you need argon. The one who claims that Dural does not boil - not right. Argon-and-arc welding can be easily welded in a duralant without disturbing its jum.

Motor mounting is also reworked under a broader snowmobile base. Here you can do by conventional metal corners and arc welding.
Leading wheel With primers, it is also easy to make yourself. Transmission of rotation from the motor to the wheel - chain. Do not try to make huge soils, if at the time of the total gas dacha under the soil-made snowmate, frozen soil will fall, then there is a high probability that the chain is broken.

The muffler can be made with their own hands. Special qualities to reduce noise can not be achieved, rapidly by the dying engine of the engine of the homemade snowmobile bear, you still do not wake up, and other beasts will step up to contact the rumbling miracle.

Mopedovsky starts reworked on a manual start. All the same in the felt boots, run the twinkling lever to the foot is impossible.

A box cooked under a bedroom on a homemade snowmobile is good to use keys and spare parts for storage. But it is better to put a bottle of vodka in such a chest of snowmobile made with your own hands. In case you break the chain. Without vodka in the frost tight, and you can live with vodka.

As you can see - make a snowmobile with your own hands in the garage simple enough. It remains only to wish good luck to self-dealers who love to ride on the snowy plains of our homeland on homemade snowmobiles!

How to make a homemade snowmobile with your own hands: Scheme, photo and device

Such a homemade snowmobile was made in a few weeks with his own hands in his own garage. The device seems to be very simple, and it will be quite forces a variety of homemaged masters.

A few years ago I smeared for my nine-year-old dog snowmobile with homemade caterpillar From the conveyor belt and plastic water pipes as a primer. At first I had doubts about the reliability of such a caterpillar and how plastic details in the cold would behave. But during the two-year winter operation, breakdowns and strong wear of the pipes did not happen. This inspired me to create a slight snowmobile for myself with the same homemade caterpillar.

On the photo above the homemade crawler Snowmobile - at the top of the single and below the double version.

Perfectly realizing that the smaller the snowmobile mass and the more the supporting area of \u200b\u200bthe caterpillar, the better his permeability on loose and deep snow, I tried to make the design as easy as possible.

The principle of snowmobile operation is very simple (Fig. 1). Four wheels are installed inside the caterpillar, which when moving rolls on the conveyor belt, on which the primatelates are fixed. And the drive of the caterpillage from the motor is carried out by chain through the slave shaft with special leading asterisks. I took them from the snowmobile "Buran".

With an engine from an ordinary motor-block with automatic power grip of only 6 horse power quickly do not get up. I was going to ride on a snowmobile, not on the rigged tracks, but along the loose snow, so I refused the soft suspension of the caterpillar and skis to reduce the mass of the snowmobile and simplify the entire design.

Caterpillars for homemade snowmobile

First made a caterpillar. The plastic plumbing pipe with a cross section of 40 mm chopped on the blanks for soils with a length of 470 mm. Then each billet saw the circular along into two equal parts.

With the help of the device shown in Fig. 2, the saw saw on the tree cut along plastic pipes for soils.

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 belt to three fastenings Caterpillar cargoes.

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. Snowmobile's 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 a swing rack of a snowmobile and a metal sublica from below - for better control Snowmobile 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 do 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 conveyor belt 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.
