Make a snowmobile with your own hands much easier than it seems. This will require a desire, several parts from the technique idle in the barn or garage, amateur skills of working with metal and a little time. Purchased nodes are likely to also need, but the cost of a snowmobile or a snowmaker with a motor collected in a few evenings will be much cheaper than the purchase.
General rules for designs
Self-timers for movement in the snow are diverse in appearance, size, layout, power, and even on the principle of movement. But in each variety there are nodes that ensure the properties necessary snowmobiles, namely:
- Do not fall into the snow.
- Move on the surface with minimal friction and in the right direction.
It is obvious that the likelihood of suiting snow and friction force depend on the weight of the unit, contact area, the surface of the surface of contact with snow. Of course, the state of snow has its influence, but which must be considered.
To fulfill the main purpose in the snowmobile design, the following nodes are always present:
Making homemade simplifies the availability of parts from specialized equipment. It is often taken spare parts from snowmobiles "Buran" or any tools and means of movement with a motor - scooters, motorcycles, motoblocks. The area for creativity when creating each node is enormous. There are many diverse and proven solutions for each part.
Simple children's snowmobiles
The easiest way to make support is to establish broad skiing under the frame. Especially attractive option to create motorcycles by the fact that for their assembly, a children's snow scooter and a tool with a small power engine are used - for example, a screwdriver, a hand-made lawn mower-trimmer or a chainsaw with a capacity of 2 horsepower. 
Children's snowmobile from chainsaws are collected, not enhanced by his frame, but for the carriage of adults in winter clothes it is worth adding strengths into the design.
Ice motorcycles
Walk along the winter river - slippery lesson. However, if you replace the snow scooter into Sanki and admit to them the motor from the chainsaw "Friendship" with a capacity of 4-5 hp, it turns out a safe means of movement on ice:
The efficiency and speed of sled on ice is significantly higher than that of other designs. But on loose snow, such a design will go with great difficulty.
Inflatable wheels
According to the cost of time, the second after snow scooters and sleigh in appeal design is a homemade snowmobile from chainsaws on wide inflatable chambers from the wheels of a truck or tractor. A uniform layer of liquid rubber is applied to their surface for strength or another flexible and waterproof material is pasted. In the circumference at an equal distance from each other across the chamber wear chains or firmly attached crossbreaks to increase the clutch. Wheels for wheels can be bicked, motorcycle or make yourself.
If there is no poloz in the inflatable design, it will be able to ride even without snow in the soil. There are such all-terrain vehicles to put frames together with the engines from the Motorcycle "Izh", "Ural" or "Dnipro". Disadvantages of design - dimensions, weight and high degree of wheel vulnerability, but on the popularity of high-speed homemade pneumatics this is not reflected.
On caterpillar fashion
Crawler supports are used more often than those at the same time performing the function of the drivers. Cause in high efficiency and reliability. This design allows you to develop high speeds, while maintaining stability and maneuverability. There are several options for how do it yourself make caterpillars for a snowmobile:
- from the conveyor belt;
- from tires truck;
- from drive wedge-shaped belts.
Across the conveyor belt should be screwed to bolts spotted along the axis plastic or PVC tubes not more than inches in diameter.
Even a child can cope with such a lightweight apparatus.
Old timer tires with a winter tread can also be used as caterpillars, if you cut off the sidewalls from them. They are not needed cross, but they will have to wash the edges in a step in a centimeter, otherwise the tire will quickly sprinkle.
Drive belts, as well as the conveyor belt, you need to equip with soils. Several parallel belts, from 2 and more, are combined between them with transverse durable primers, attaching them to straps rivets or with screws. The distance between adjacent hysteries should be equal to the step of the leading sprocket.
Caterpillars from conveyor belts or belts often amplified by chainthat increases the reliability and durability of the propulsion.
In such snowmates, lightness is easily combined with a reliable drive.
One of the varieties of caterpillar snowmobiles is a motorcycle, which was named in similarity with a harp dog for Nart. Damage to maneuverability was facilitated by the design, the traction effort also increased. But this is the most effective mechanism for towing in the snow.
To change the direction you need to apply considerable efforts with the displacement of the center of gravity of the motorcycle.
The main dimensions for the assembly of the double snowmobile, indicated in the drawing, will help make driving comfortable. The remaining sizes will depend on the presence of spare parts, the assembly scheme.
When moving discomfort from the oncoming wind weakened by installing a motorcycle glass and mud flaps for the legs. But completely closed on this transport from the cold wind is impossible. For comfort, you need a fully closed cabin, which means it will increase weight and will need a more powerful engine.
A snowmobile with a car engine is designed for long-distance long distances. With thermal insulating body material, the trip is comparable to the comfort of a passenger car.
And the easiest way to achieve comfort is to simply put a rear-wheel drive car on wide supports like skis, caterpillars or pneumatic wheeled chambers, as well as to start the drive of the regular wheels to snowmakers and attach the front ski to the steering bump.
It will be useful in the manufacture of a replaceable scheme for changing the wheels to ski and back, if used for rewriting parts.
Upgrade homemade snowmobiles
Having a simple snowmobile at your own hands assembled, it is impossible to stay from thoughts to improve transport. First of all, it is possible to reduce the effect of frosty wind. For this, ready-made fairies are usually used, windshields - for example, like the popular "Buran":
In short winter days, light from motorcycle or car headlamp will be useful. To lamp the lamp, the generator will be required. For mini-structures it is enough to install a bicycle generator with a drive from a motor gearbox. High-speed devices will require more powerful lighting.
There is no limit to perfection. Once the Snowmobile collected can be easily achieved all new devices for work, comfort and reliability. Many forums on this topic exist on the network, allowing you to transfer your own and taking into account someone else's experience in designing winter vehicles.
ATTENTION, only today!
My homemade Snowmobile With a rubber caterpillar, it was capable of moving not only in shallow snow, but also practically on any off-road.
The only thing he did not have enough - stability on a slippery road. To eliminate this drawback, I decided to install two controlled wheels on my snowmobile.
Then it will be possible to ride not only on the downstream snow, but also in the open soil.
The big support area of \u200b\u200bthe caterpillar allows a snowmobile to overcome off-road, streams and steep lifts.
Snowmobile design
Snowmobile double, capable of towing several sleds with children. The frame was welded from metal r pipes of square section, footrests and skiing - wooden. In the design V. A four-stroke engine with a capacity of 9 hp is applied.
Such engines have a reduced gearbox and automatic grip in the oil bath. They are used on mini tractors, motoblocks and other gardening techniques. In the manufacture of your snowmobile, I took some nodes and details from the snowmobile "Buran": a caterpillar, two pairs of carts with four rollers, the driven shaft of the caterpillars assembled and the leading stars. All this bought in stores selling spare parts to snowmobiles.
Rollers on carts " Burana"Asymmetrically fastened, but I reddished this node so that their pairs are located symmetrically. To do this, combined two trolleys with a bolt and a special frame from a profile of 20 x 20 mm.
The balancing of two carts, which was thus, attached the rear pendulum with a slave shaft and supporting the caterpillar with rollers (wheels from the children's scooter).
The entire design of the caterpillar (Fig. 1) is attached to the rear pendulum to the base of the rectangular frame of the snowmobile made of a metal pipe with a cross section of 30 x 30 mm and with a wall thickness of 1.5 mm.
Snowmobile steering made using conventional tap threaded clutches and Signs, which allowed not only to simplify the design, but also do without complex machines. Such ski management I have already done on many of my homemade snowmates, and it has shown perfectly in the process of operation.
Production of racks
Swivel skis racks (Fig. 2) are made of pipe with a diameter of 3/4 ", and a semi-leaf tube is pressed to the additional rigidity to it. The racks are attached to the steering beam also with the help of plumbing Signs and couplings.
The ski stand is inserted into a squint, which is wrapped in a coupling welded to a transverse steering beam with a cross section of 50 x 50 mm on the frame. Printing the nuts the rack. Thus, you can adjust the height of the rack and the alignment of the ski, without changing the length of the steering thrust.
If you drive a snowmobile only on loose snow, then the ski fastening to the racks can be made hard. With such a suspension snowmobile will be more resistant on loose snow.
If you have to ride on the rod roads, the ski suspension is better to do on springs or shock absorbers to reduce shock loads on the racks and frame.
I used the twisted springs in the suspension, which put on the snowmobile trolley "Buran". They are on sale and cost inexpensively. The rigidity of the two springs on each ski is quite enough.
For a snowmobile, I adapted wooden hunting skis, regaining them up to 115 cm. In order for the skiing, it was not under hardening, but destroyed it, fixed on a special arc on the wear, and the metal rolling metal was installed on the bottom, with which it is much easier to control a snowmobile on the rolled road.
Since the snowmobile is mainly intended for adolescents, I found it necessary to reduce its maximum speed up to 15-20 km / h due to lowering turning from the engine to the drive shaft of the caterpillars. But the traction effort from this has become more, which allows you to tow a few sleds with children. Snowmobile control is carried out by one motorcycle type gas handle. In order to start moving, it is enough to increase the engine speed - this leads to the triggering of the centrifugal clutch, and the snowmobile begins to gain speed. When dumping the gas, the centrifugal clutch disconnects the drive, and the snowmobile stops.
Homemade Snowmobile: Instead of Ski - Wheels
To replace the front skiing wheels of any changes to the snowmobile design did not have to do. With a ski, I installed the hubs and wheels from the sports card instead. True, I had to make a specially elongated axis of the wheels.
In the course of the first tests of snowmobile, I realized that the design is quite workable - the car is well listening to the steering wheel and keeps the road. But for crossed terrain and dirt roads with deep rings, the diameter of the wheels was clearly small, and the spring suspension without shock absorbers was weak.
It was necessary to finalize the struts of fastening ski-wheels to install a shock absorber from the moped and make a disc-adapter for fastening the wheels of the larger diameter from the Tula motorcycle.
The machine with these wheels began not only to overcome deep drifts in winter, but also to cope with the risks of dashed roads. Low pressure on the soil due to a wide rubber caterpillar provides all-terrain vehicles in any road conditions.

Give our person a motor - and he will make a motoblock, tractor, boat or homemade snowmobile from it. It all depends on the climatic zone in which Kulibin lives. And since the territory where the snow cover lies almost six months, in our country there is quite extensive - the question "how to make a snowmobile" is quite relevant.
Homemade snowmobiles last season - video review.
Even the models developed by folk craftsmen and then produced by small-sector parties.
Important! All constructions offered in the material are not a means of movement in terms of the law. They can be moved to their own fear and risk on deserted snow-covered spaces, and not at all on roads, including winter.
Snowmobile with your own hands can be done on one of the concepts
On pneumatics
In essence, this is a mini-tractor with original wheels. Due to the large area of \u200b\u200bcontact with the surface, even loose snow overcomes. It is usually done from a motorcycle or motoblock.
Important! Do not confuse this vehicle with floating all-terrain vehicles on similar wheels. In the snowmobile other ratio of the total mass, and buoyancy of pneumatic wheels.
Classic design
With the leading caterpillar and steering skiing (skiing). The project, proven by the years, is complexity represents the manufacture of the caterpillar. The vehicle is obtained by universal, easily moved along any roads, including the crushed terrain. In some cases, homemade is superior to many industrial samples.
Use the driving wheel
In this case, the wheels with primers. For this principle, wheel steamer works. The advantage of the design is the relative simplicity of manufacture. The disadvantage is insufficient adhesion with the surface of the propulsion, it is possible to slip on a heavy relief. Such models are well obtained from mopeds and motorcycles, giving the second life to "donors".
Aerosani.
The easiest in terms of implementation, homemade snowmobile. It is enough to put the trolley on the support skiing, and install a traction screw to any suitable motor. In addition to some difficulties associated with the technique of manufacturing the drive screw - there are no more problems in the construction. Disadvantage - such a design moves only on a relatively level surface. Another problem is with a small power of the motor, movement against the wind is difficult.
By donor type, or the use of various types of engine, homemade snowmobiles are divided into the following types:
- Use of a motor from chainsaws. Small power does not allow a lot of weight on such a vehicle. Therefore, snowmobiles from chainsaws are usually single;
- Moped or motorcycle. Fairly simple in the manufacture of the project. The engine is designed for a certain load, it remains only to redo the leading element and replace the front wheel on the ski;
- Motoblock snowmobile. The design is quite complicated, but reliability is almost not inferior to the factory. The engine is designed for long work under load, in the kit there is a gearbox, which expands the possibilities of means of movement. In addition, the power plant can be removed for the summer season, and use a motor-block for its intended purpose;
- Snowmobile with your own hands on the basis of a car or, using a motor from a passenger car. A rather rare type of homemade, for the manufacture requires professional equipment and complex engineering calculations. But snowmobiles made on the basis of cars are distinguished by high comfort, safety and reliability.
Those who love often ride fishing in winter, often face the problem of passability. After all, it is not always even on an SUV directly to drive up to the bank of the river and even more so for the place of fishing itself. Exit from such a situation will serve a caterpillar snowmobile. However, the price of such equipment in stores is sometimes not available, and therefore the need arises in the manufacture of such a device with their own hands. In today's article, we will look at how it is done on the caterpillars and that for this you need to have.
Caterpillar
First of all, it should be started from the most complex element of the construction of a snowmobile - caterpillars. Along with the engine, it is the main motor element of the whole technique. In order to do it, first need to make up the drawings of self-made snowmobiles on the caterpillars (approximately as in our second photo).
So you will know the exact sequence of work performed and will not forget about any small detail. And now about how to make a caterpillar in practice. To do this, we need to take a plastic tube (about 40 millimeters diameter) and 2 strips The number of pieces of stripes depends on how long your caterpillar is. Working with these details, or rather, their processing is easily produced on circular or (grinder). At the same time, it is necessary to cut the part on one wall at a time. It is necessary to ensure the accuracy of the work performed. How to connect a transport tape with halves of a cropped pipe? To do this, we will need two at the same time the diameter of their thread should be about 6 millimeters. If you combine this value of the elements with the manufactured structure, the step between the output of the output will be 93 millimeters.
With the "baiting" parts of the pipes with cut-off side, it is necessary to endure the distance between them. If the offset will be 3 or more than millimeters, this will lead to the inconsistent work of the teeth of the drive gear and the tape itself, which is why sliplocks will begin in the snowmobile. And this is already leading to the loss of manageability. This discrepancy can lead to the fact that the tape can simply slip from the rinks.
It is important to observe the dimension of the caterpillar. What is long it will be directly depends on the engine power on which the homemade snowmobile will work. On the caterpillars you need to calculate the nominal pressure of the whole technique on its plane. Thus, the curb weight of the snowmobile relative to the roadbed should be no more than 0.4 kg / cm 2.
How to produce tape drilling?
Homemade snowmobiles on a caterpillar go are quite normally working on ribbons drilled by the usual drill. However, that the device worked as long as possible, you need to drag the drill to work in advance. Pre-acquire a tool designed to process wooden surfaces. In no case do not use the metal drills.
The remaining parts of the chassis
With the rest of the aggregates, the case will be easier. For example, such nodes as axis and rubber wheels, "Buranian" leading stars and protected bearings can be purchased in any specialized store. By the way, the wheels are better to purchase inflatable. This technique will be softer on the go. The axis can be taken from a simple garden trolley (two-axis). If necessary, you can cut or, on the contrary, expand it to suitable values \u200b\u200bof technology. If you do not have the ability to purchase a leading shaft in the store, you can try to make it on the lathe. With the independent manufacture of the shaft, pay attention to the fact that in its size it is well tapped bearings.
Homemade Snowmobile on Caterpillars: Rama
We will perform the main carrying function and hold all the details, including the engine, in the same whole. By the way, you can use the power plant from the motorcycle along with the gearbox. But back to the frame. It we will make it made from the steel section with a diameter of 25x25 millimeters. At the same time, it is necessary to weld it in such a way that there are two longitudinal and three crossbakes. The presence of these parts on the frame will significantly strengthen its design.
Complete work
Finally, how to install on the homemade snowmobile on the caterpillars in the process of assembling a snowmobile here you need to make two swivel sleeves. This will be your steering mechanism. How it's done? To the front beam you need to weld a watering clutch with an internal thread by 1/3 inches and screw the nozzles with external threads in them. Nozzles already have ski racks and welded tushki for the steering thrust. By the way, you can use skis from the ordinary children's car "Argamak". But before that, pre-prepare them for the installation: Give the corners of the fastening of the rotary rack and produce the metal subsidence. This will significantly improve the maneuverability and quality of high speed snowmobile.
As soon as winter begins in our country, taking into account the climate, two-wheeled transport is cleaned into the garage until Spring. It is impossible to use a car for movement due to abundant snow. And here to help all motorists who want to move along the snow-covered road, a snowmobile snowmobile comes from the caterpillars, which can be made of a motor-block with their own hands.
The ability to buy an additional vehicle is not all, but everyone can independently construct a homemade tracked snowmobile from a motor-block.
Advantages and features of a homemade snowmobile
- The vehicle has a mechanical drive and a tracked fiberboard, when driving on which you will not get stuck in the snowdrifts.
- Management occurs at the expense of skis, and the steering system is ahead, so you can easily manage it.
- The price when buying a vehicle is important. Therefore, if you consider, the cost of making a snowmobile will independently be lower than five times than buy it from the manufacturer. And even cheaper it will come out due to the available motor-block and other details.
- Reliability - where a person does not pass and will not erupt the car, the snowmobile will overcome all obstacles with ease.
- If the snowmobile is manufactured with your own hands, then the designer is suitable for the choice of details. By doing everything yourself, you are responsible for the quality of your design. In addition, paying great attention to the nodes of the mechanism, you make a snowmobile everywhere.
Homemade Motion Snowmobile Device
This is a sought-after invention that can be made independently in the presence of high-quality details. The motoblock is taken partially (individual details) or used completely. If you decide to use it not in full configuration, it is necessary to welcome the carrier frame with the rear axle, steering fork and wheels. The most difficult stage at the same time becomes the transformation of the working shaft of the motoblock to the drive gear.
The most practical and universal solution in the manufacture of a self-type will be the use of parts from the motoblock. It will only be necessary to withdraw from the finished motor-block fork steering and engine.
Motor can be placed in the back of the structure.
Before starting self-making design, draw the drawing, collect all the necessary material, prepare the tool, and you can start. The design is quite simple and any person will cope with it, this is not necessary for technical education and some skills.
If you have not completed the engineering faculty and it is difficult for you to draw up a drawing, use our.

Making a snowmobile on a caterpillar go
Before starting work, decide on the tool. You can say with 100% confidence that you will need: various screwdrivers, hammer, welding, pipe bender (if there is no ready-made frame).
Before preparing a drawing for self-making snowmobile, read the standard configuration.
- Frame. In each snowmobile there is a frame: the more complicated the design, the more reliable and most of the frame should be. The optimal option is to take from a quad bike, scooter or motorcycle. If there is no such part, it is possible to weld it yourself from pipes with a diameter of at least 40 mm.
- Seat. Snowmobile seat should be durable, since the design itself is quite low.
Mandatory condition: The seat must be made of waterproof material.
- Engine. Choosing the engine, pay attention to its power. If you want a powerful snowmobile was, the engine must be so.
- Tank. The capacity of 10-15 liters made of metal is perfect for the fuel tank.
- Skiing. If you do not have ready skis, which can be adapted for snowmobile, they can be made independently made of wood. It is better if it is plywood not less than nine-layer.
- Steering wheel. When choosing a steering wheel, think about your convenience. It is best if it is borrowed from a two-wheeled unit.
- Caterpillars The manufacture of caterpillars is perhaps the most difficult part in all self-propelled.
- Drive unit. For caterpillars rotate, you will need a drive - it is best to use a chain from a motorcycle in this case.
Frame
If there is no finished frame in the presence, it is easy to cook from the profile pipe, and the form to give with the help of a pipe bender.
If it is not possible to make calculations and make a drawing, then for example, use the drawing from our site.
As soon as the frame is collected, treat it with an anti-corrosion composition and cover high-quality paint, which will withstand and moisture, and frost.
Caterpiles
All who used to independently designed a tracked motoblock note: the manufacture of caterpillars is the most difficult process in the homemade.
The easiest way to construct them from the tires from the car. This option is the most prominent - high quality and low-cost. The item is made according to a closed circle, so the tire break cannot happen.
Snowmobile Caterpillars (Tires)
Instructions for the manufacture of caterpillars:
- From the automotive tire: take a tire and cut off the board (it is better to do a sharp knife). It is necessary to cut so that the flexible part with the tread remains.
