During the cold weather, transport on two wheels becomes irrelevant, and sometimes impossible to drive on the snow-covered expanses even by car. What to do in a situation if there is no money for the purchase of a more adapted to the harsh winter of transport?
In this case, you can make a homemade snowmobile. Winter vehicles most often equipped with a caterpillar drive, the steering skis are installed in the front. The snowmobile has high permeability, light weight (70-80 kg), which allows him to ride both valuable snow and on the rolled snow-covered roads. It is easy to control this vehicle, and the developing speed is small. So ride on a snowmobile in the winter, this is not only convenient, but also safely.
Features of homemade snowmobiles
Sale snowmobiles in the CIS are engaged in a huge number of companies. But the prices of them are high even for families with decent income. If you do not want to overpay the money for advertising and are a hardworking and creative person, then try to make a homemade snowmobile.
The self-propelled self-propelled hand is 7-10 times cheaper than the cheapest models manufactured by the factory.
The success of the personnel production of snowmobile depends on several factors:
- your personal skill;
- your engineering thinking;
- the presence of parts and aggregates from other snowmobiles, motorcycles and other things.
It should be borne in mind that driving on a snowmobile, as well as on any vehicle, is associated with increased danger. Despite the fact that homemade devices are usually not able to develop speed more than 15 km / h, to the quality of parts, to welding, to the fastening of elements bolts should be approached with all seriousness. The issue of operational safety and reliability of the final unit must be the main one for any person who has intent to make a snowmobile with their own hands.
Preparation
Before proceeding with the production of snowmobile, you need to calculate the main parameters of the device. If you are a little constructor engineer, it is appropriate to make the drawing of the unit. In principle, all snowmobiles are arranged equally and simple. Your task is to make a reliable apparatus according to the sample and the likeness of all other versions of this vehicle class.
What will be required for manufacture:
- Pipe for frame, for suspension and other frame elements.
The experimental method found that the optimal diameter of the pipe was 40 mm. If you use a profile, then 25 x 25 mm will be enough. Wall thickness - 2 mm. With smaller parameters, the stability of the apparatus to deformities will be reduced. At large - the machine is lost, which, accordingly, will affect the already not brilliant driving characteristics.
- Wheels with rubber on the axis.
Wheels are suitable from quad bikes (small models with a wheel diameter of 30-40 cm), some carts, etc. A total of 2 axes with 2 wheels each.
- Wedge belts or conveyor belt.
The main element of the "caterpillars". The optimal thickness is 3 mm. This is enough for stability and wear resistance.
- PVC pipes.
Of these, soils are made - the second element of the "caterpillars". The optimal diameter of 40 mm with a wall thickness is 5 mm.
- Motor installation.
As a rule, an engine, a carburetor, fuel tank from a motorcycle is used.
- Transmission mechanism.
As a rule, the stars and a chain from a motorcycle, star from snowmobiles are used. Lead shaft from any unit suitable for dimensions.
- Ski guides.
Optimally to take skis from another snowmobile. Since this element should be the most reliable designed for the load of the aggregate itself, plus a driver and possible passengers.
- Steering wheel.
As a rule, the steering wheel from the motorcycle is used, respectively, with a gas handle and a cable.
- Platform, seat, body.
In principle, you can do without a platform, consolidating the seat (s) and the body (optional) directly on the frame. But sometimes there is an additional platform on the frame, for example, from wooden boards, which provide minor depreciation, allow you to place several seats, and at the same time we melt the design.
- Shock absorbers.
This element makes an additional complexity in the design. Therefore, they often cost without it, especially if it is supposed to ride the snow. Depreciation is installed on the front suspension and driver seat. You can take from the old snowmobile or from a motorcycle.
- Small parts.
In addition to those listed above, other standard parts will be required to make a snowmate: bolts, studs, nuts, hinges.
How to make: instruction
First, the frame is boiled - frame. Obviously, the greater the larger the frame, the harder it will turn out the device and the slower it will move. The optimal length of the frame is 2 m plus / minus.
On the frame consistently recorded:
- presenter shaft with host agent;
- power plant with transmission star and gas tank;
- front wheel axis (motionless mounting to frame with welding or bolts);
- rear wheel axis (attached fixed with the help of a moving guide element);
- front suspension with steering wheel construction and guide skiing (skiing);
- seat (s) and body.
Caterpillars are made from drive wedge belts or conveyor belt. The optimal width of the caterpillars is from 40 to 50 cm. With a smaller width (40), the snowmobile will be more maneuveren and better manage. With a larger (50+), the passability of the device improves.
The function of the soils is performed by the PVC pipes indicated above the diameter in half. They are attached to a rubber basis with the help of bolts and nuts. Insufficient width, wedge belts can be fastened with each other with metal primers.
In order to be able to adjust the tension of the caterpillar cloth, the rear wheel axis is attached using a movable guide element, which allows to fix the position of the axis in a certain position.
Additional comments:
- The center of gravity must have about the construction center. Since the power plant is fastened ahead, the driver's seat should be shifted to the center over the front axle or a bit offset.
- The distance between the driving shaft and the power plant must be minimal to minimize the loss of energy transmitted to the shaft.
- If you install a shock absorber under the seat, the front support of the seat is attached to the profile arc hard, and the seat rests on the shock absorber.
- If you make a snowmobile with a calculation on a large load, then it is advisable to set an additional ski of the base for removing part of the weight from the caterpillars (between two tracks). This ski, a long 50-70 cm, is attached directly to the frame. However, such a design assumes a more accurate preliminary calculation, followed by alignment of the height of the "legs", which complicates the production of a snowmobile.
- In the snowmobile tires, it is advisable to maintain low pressure to avoid the rapid wear of parts and high fuel consumption.
The considered snowmobile option is the easiest of construction. In the presence of tools, the welding machine, it can be assembled in the garage without problems.
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.
Many agricultural owners do not know what a motoblock is. It is used to handle a small land area. Most often it works in the warm season, but not everyone is aware that you can remake the monoblock to the all-terrain vehicle. Make such a vehicle with your own hands for everyone. If there is a small amount of money, the device will even turn into a snowmobile or quad bike.
Motoblock snowmobile with their own hands
Motoblock self-made vehicles have a wide variety. Most often, the craftsmen alter him into a miniature tractor. The only difference is the high level of comfort, in comparison with the initial option. When creating it is necessary to take into account several important details: the bias of the center of gravity, an increase in the front axle and installing a new differential. Now there are on sale whole kits that allow you to increase the functional features of the monoblock.
For those who want to move along the snow-covered roads there will also be a good solution. Snowmobile to create with your own hands is simple enough. The most difficult task is to develop and install the chassis on four wheels. A feature of such a device can be considered minimal pressure on the surface. It is best to make special coupling devices with a soil. To do this, they are made according to the wheels of the motoblock.
For the owners of heavyweights, everything is much easier. The structure of the vehicle actually remains unchanged. Here it will only be possible to fix the primer on the surfaces of the wheels.
Motoblock homemade all-terrain
It is necessary to determine the capacity and carrying capacity of the all-terrain vehicle. It is best to prepare drawings in which you need to designate the location of units with nodes. Specialists recommend putting the engine one that uses a forced cooling system. These include engines with air and water cooling. Its power must be selected at its discretion.
For many, it is unclear what engine type to choose - gasoline or diesel. Here it is necessary to be guided by personal preferences, since both have their own drawbacks and advantages. The chassis must be with an independent and floating suspension. It requires everything to be thought out for its manufacture, but if successful will be ensured by the comfort of driving.
First you need to choose the type of base. For such purposes, the Frame of Motorcycle Izh, Ural or Dnipro is perfect. I want to pay special attention to the basis based on IL, as it has good handling. To have a floating suspension, we will need to connect the spars with a sleeve with a sleeve and counter. After that, the suspension will allow the vehicle to go smoothly.
As for the wheels, it is best to use a chamber from trucks. For attachment, the metal hub is most often used. Cameras of cars KAMAZ are greatly popular in the manufacture of all-terrain vehicles. Installing aggregates is one of the most time-consuming processes in the manufacture of all-terrain vehicles. This tap comes after mounting the suspension. In parallel, you must connect and configure brakes, clutch and exhaust system.
As soon as the all-terrain vehicle was assembled, it is necessary to test it. If there are some kind of malfunctions, then immediately need to be eliminated.
Motoblock swinging with your own hands: Important details
For the manufacture of a swamp, it will take all the same. The only difference is the need to use low-pressure wheels. It is they who provide good permeability of off-road, and also allow the vehicle to move without any problems through obstacles. In the manufacture, it is necessary to take into account the weight, since too heavy swamps will experience problems when driving.
Some people construct a crawler-based swamp. Of course, this option is ideal for driving on the dirt or a soft surface, but it is more difficult to develop it.
Motoblock tracked all-terrain vehicle: design features
Cater-based aggregates are most often found in rural areas. To independently make it not need to be changed completely running part. It is required to purchase a large truck wheel of such sizes that can easily gain themselves and hold on between the front and rear wheel of the motoblock.
First you need to remove the side of the new one. Because of its thickness, it will be difficult to do it. Next, we stretch the resulting rubber "caterpillar" on the motoblock. If, when testing a vehicle, the rubber tire is running, it is best to choose the optimal size. This option is the most affordable money and easy in production. The service life of such "caterpillars" depends on the operating conditions.
Of course, you can fully improve and replace the running part, but it will cost a decent amount, and it is necessary to spend a lot of effort. True there is one thing - the clutch with the road will be better.
Schedule as the engine was going to use 6-10l / s, and the snowmobile mass should be small, from authentic caterpillars for snowmobiles flatly categorically categorically refused. I was going to make a caterpillar myself for about 4 meters and 50 cm wide., But it was not possible to purchase a suitable size conveyor ribbon in any way, I had to make the caterpillar in short with a long about 2.7 m. The width of the caterpillar came out 47cm. For the manufacture of the caterpillar made a conductor with which the feather drill was made by the holes in the conveyor belt.
The store acquired four wheels from the trolley with bearings, two soft stars from the burana, and two 205 bearing for the driving shaft, a plastic pipe with a diameter of 40mm. Long 8 meters, everything else for a snowmobile construction was found in the barn, a square tube 25x25mm, from the old office table for the frame, cutting the corners, water supply and couplings.
Made drawings for Tokary and a week later I made the necessary details for me. The process of assembly is clear in photos, everything is very simple, and the principle of work of the future snowmobile is about such a hard surface (Rocky tracks) snowmobile moves on wheels, ski that is inside the caterpillar does not concern the tricks, only with its sides does not give caterpillars to shift towards, thereby There is no additional load and wear of the cams without lubricating the cams with snow, and in the loose snow, the focus is skiing.
During the first day, I made a caterpillar and a leading shaft, for fastened it on the frame, since the wheels for the wheels did not have time to do turner.
The turn of skis did it very simply, a water clutch was welded to the transverse beam, they screwed off with a splining for skis and a steering thrust. In such a way, everything is very simple and reliable, no bushings and turning works only the presence of solidol and long service life is provided, and turning and screwing the Sgona can adjust the height of the ski rack.
Fastening the front wheels without adjustment, fastening over the wagons done movably moving the axis takes the caterpillar stretch.
The steering is solid and not regulated (this is a temporary option)
Chain adjustment, engine displacement.
Watch the photo (when you click on the photo, they increase)
That's what I did, unfortunately I did not have time to establish a reference skiing inside the caterpillars, but already rode the truth now on the snow surface, the present and conclusions to do early, but even without a reference skiing the tracks hold snowmobile and do not break into the beats, which is clearly visible on Photos, the result is still satisfied, the design turned out very light. I have not yet, I want to check the cut, I want to check how a short caterpillar will behave in a deep and loose snow, the distance between the ski can be reduced, and I want to put the engine with a 125cm3 from the scooter, or 150cm3 soup days speed from a quad bike, well, of course, to work on the design nnom, but it is probably a future winter, although you know.
Motoblock is a universal device for agricultural work. Universal, the device is considered due to the fact that the design assumes the possibility of its reorganization. From the motoblock you can make a quad bike or snowmobile with your own hands. Such re-equipment does not require significant financial costs or skills, and one machine will perform many functions.
Redoing the motoblock under the snowmobile is advisable at least because of the price: the cost of the most primitive machine for moving through the snow ranges from 3.5 thousand to 5 thousand dollars. There are also models worth 10 thousand dollars.
You can not buy an ordinary snowmobile, therefore, in the acute need for a winter vehicle, you can use a fiberboard. Such homemade are tremendous among rural residents.
Motoblock homemade snowmobiles
Not every motoblock is converted into a snowmobile, so before making the purchase of a power unit, pay attention to the following technical features:
- The presence of a rear trailer coupling device.
- The engine is not lower than the middle class.
- Mandatory manual control.
- Air cooled motor arrangement.
When the power unit is purchased, proceed to its re-equipment. The main tools and details that will be needed for this make up a small list:
- welding machine;
- pipe bender;
- caterpillars, two broad skiing or wheels;
- auxiliary details.
The main thing is to choose all the details necessary for the conversion. Some of them are manufactured independently. Construction begins with a selection of a snowmobile model. Snowmobiles are divided into two main classes: wheel snowmobile and snowmobile on caterpillars. It is advisable to make a layout.
Alteration of Motoblock in Snowmobile
The first and second stages are to manufacture the frame and fastening the power unit:
- Rama is made of old motorcycle or cars. Pipe bender will help to give the form.
- The joints are processed by point welding.
- The engine is moved to the center of the case design.
- We place the engine on a specially manufactured platform with fasteners for fixing the motor itself.
Motor fastening on a special platform is very important, since otherwise it can be clogged with snow and result in burning.
- The playground is welded to the subframe.
- Thanks to the displacement, it is possible to use a manual control method.
Installation of the steering wheel and landing place is selected by the master independently - the main thing is to be comfortable to control the device. Depending on the power of the motor, the snowmobile can accommodate several passengers.
The third stage lies in the installation of the poloz. Most often it is two broad skiing, which are attached to the steering column using hinges. The front part, which is fastened by the share, must be equipped with shock absorbers.
Instead of skis, you can use caterpillars or wheels (pneumatics). Each option has its pros and cons.
Drawing of a simple snowmobile
Mini snowmobile do it yourself
Mini snowmobile - very popular vehicles in the winter season. Such an aggregate is found in the suburbs, and in the village it is simply indispensable. At the same time, mini-snowmobiles have plenty of advantages over standard snowmobiles:
- High passability and maneuverability.
- Economical fuel consumption.
- The method of manufacturing mini-snowmobile does not cause difficulties.
- Available manufacturing materials.
- Takes up little space in the garage.
Thanks to compact dimensions and minimum mass, the unit passes through the most hard-to-reach places and practically does not fall into loose snow. If we competently think over all the manufacturing nuances, you can do the minimal financial costs for the re-equipment of the aggregate.
Motoblock Snowmobile on Wheels
Wheel snowmobile is popular due to sufficient maneuverability. But there is a negative point - the wheels may fall into the snow. Snowmobile on wheels or low pressure chambers (pneumatics) is characterized by ease of assembly. Wheels can be purchased in the store or do it yourself.
The main attention should be paid to the choice of the power unit - the motor on the motoblock should be as powerful as possible, otherwise the unit will not be able to perform its specific functions - moving through the snow or ice.
It is important to properly construct drives and a frame of all-terrainaries. It is desirable that each wheel has a separate drive. This will significantly simplify the management in extreme conditions. For snowmobile, four wheels are most often used, as the three-wheeled machines are less stable.
Often combine low pressure wheels and wide skis. Thus, the stability and passability of the apparatus increases, but maneuverability does not decrease.
Homemade snowmobile
Crawler Snowmobile
Motoblock snowmobiles on caterpillars are characterized by high permeability. But because of the huge masses they are heavier to manage - maneuverability worsens. In addition, the cost of installing the caterpillars differs from skis or wheels.
But it is a long and complex process. In this case, there are several features of a tracked car for passing through the snow:
- The motor is installed in the traction part, so you will have to significantly redo the frame of the motoblock.
- If the caterpillars are made independently, attention is paid to the quality of the compounds.
- Seat and steering is installed so that the equilibrium of all components of the unit is respected.
You should not accelerate on tracked snowmobiles to high speeds. This can lead to an accident.
Alteration of the motoblock in the caterpillar snowmobile is not hard, the main thing is to take care of security.
Snowmobile type tube-palker
It is possible to allocate in two main groups depending on the material of the snowmates: "tubes" and "stickies". They differ in the material used for the tracks. In order for the design of the caterpillars to be stronger and resistant to deformation, tubes (conventional plastic water supply) are used. But in this case, the grip of caterpillars and snow is low.
Drawing of caterpillars for a snowmobile tube
In another variation for tracks, a wooden timber is used. The service life of this method of arrangement of the caterpillars is not very high, but the grip with the surface is much higher.

Homemade swamps in their principle of action and design completely repeat the snowmobile scheme. The principle of both one is to reduce the pressure on the surface at which the unit will move. To create a swamp, it is important to pick up or make the wheels or caterpillar - the width should be much more than the standard.
To create a motor-block snow-born, stick to the approximate plan:
- Strengthening the frame or its reorganization is carried out using the installation of additional pipes.
- Motor and steering wheel are placed on the frame.
- Here the chassis and front sprocket are installed.
- An intermediate shaft is installed with rubber lining.
For the chassis, you can use tires or caterpillars. Each option is special in its own way, and all the characteristics for creating a caterpillar and wheeled unit are described above.
