Children's snowmobile on gasoline do it yourself drawings. Making a snowmobile with your own hands - it does not happen easier! Drawings, options for finished works

With the beginning of winter, especially snowy, problems associated with movement appear. Few people know that the snowmobile can be constructed from the subwoofers as an alternative vehicle in winter conditions.

At the same time, there is no need for serious costs. Moreover, if there is a large number of snow on the car you will not leave, but the snowmobile will allow moving in such conditions without any problems.

The assembly of any design begins with the development of drawings. They can accommodate all the necessary aggregates, after which it is possible to proceed to the practical implementation of the idea. Therefore, at this stage, it is necessary to determine the chainsaw of which brand is suitable for the realization of the conceived.

Selection of chainsaws

In the outlets you can meet several chainsaw models. The most popular of them, it is a chainsaw "Friendship", chainsaw "Ural" and chainsaw "CHTIL". Before choosing, you should think well, comparing their specifications.

Chainsaw "Friendship"

This is the easiest chainsaw that can be used as a snowmobile engine. As a result, it turns out an elementary design without anything superfluous.

The only drawback is a big weight with relatively low power. In addition, there are no parts for fastening safety housings. In addition, this design is outdated in all indicators.

Specifications:

• Power - 1 kW;
• Weight - 12 kg;
• Engine (two-stroke);
• Tire length - 45 cm;
• Fuel (gasoline).

Chainsaw "Ural"

This is a specialized model that has greater reliability, power and less weight, with respect to power. This is an environmentally friendly unit capable of working in extreme conditions.

If it is decided to use the "Ural" chainsaw, then this is a good choice. Its technical characteristics are fully compliant, declared.

Specifications.

• Power - 3.68 kW;
• Weight - 11.7 kg;
• Engine (gasoline two-stroke);
• Overall dimensions - 46x88x46 cm;

Chainsaw "CHTIL"

It is also suitable for creating a snowmobile with your own hands. This is an environmentally friendly apparatus, absolutely harmless to humans. The main advantage of chainsaws is low weight and silent in work, compared to the chainsaw "Ural", and even more so, if compared with the chainsaw "Friendship".

Making a snowmobile snowmobile diagram with their own hands

Snowmobile assembly schemes from the "Ural" chainsaw: 1 - steering wheel; 2 - fuel tank (from the chainsaw "Friendship"; 3 - force aggregate (from the "Ural" chainsaw); 4 - Ski rail sleeve (pipe with a diameter of 30-2 pieces); 5 - steering ski (2 pcs.); 6 - drive gear wheel caterpillar (Capron, S15 sheet, 2 pcs.); 7 - caterpillar (from the snowmobile "Buran", shortened); 8 - frame; 9 - reference roller (from potato sorting, 18 pcs.); 10 - backrest booster (pipe ½); 11 - Tensioner caterpillar (2 pcs.); 12 - Tension gear wheel caterpillar (Capron, sheet S15, 2 pcs.); 13 - Bearing №80204 in the case (4 pcs.); 14 - Dog-trunk of the bottom-plywood S4, board board S20); 15 - seat (plywood cover S4, foam, leatherette); 16 - 1st chain transfer stage; 17 - 2nd Chain Transmission Stage; 18 - backrest seat (pipe ½ inches); 19 - driven asterisk of the 1st chain transmission (a large stroke of the track, intermediate shaft); z \u003d 38; 20 - the leading asterisk of the 2nd chain transmission stage (small stroke of the chaimmer), Z10; 21 - driven asterisk of the 2nd degree of chain transmission (drive asterisk of the drive shaft of the caterpillars), Z18; 22 is the leading asterisk of the 1st stage of the chain transmission (asterisk of the output shaft of the gearbox), Z12; 23 - lever swivel fist; 24 - steering thrust (2 pcs.); 25 - steering shaft with a compartment; 26 - Balka front Bridge (pipe diameter 30); 27 - drive shaft of the caterpillars; 28 - Tensioning axis of the caterpillar.

Without the creation of the scheme and drawing, it is unlikely to connect together the basic structures units, such as:

• Engine;
• Transmission;
• Skis and caterpillars.

To simplify the design process, you should take the caterpillar from the Burand Wide. If a children's option is constructed, then there will be a skis.

Stands

Steering Ski: 1 - poloz (Capron, S20 sheet, from a children's snow science); 2 - spring (normally stretched, from the rear shock absorber of moped); 3 - Supplement springs; 4 - cut (duralumin corner 20x20); 5 - Spring cover (corner 35x35); 6 - fastening the spring to the lid (bolt M8 with a washer); 7 - reference lever (pipe 30x30); 8 - spring fastening springs - forks to the lever of the ski (steel, sheet S2); 9 - spring fastening lever to ski (steel, sheet S2); 10 - axes (bolt M8, 2 pcs.); 11 - Rotary fist stand (bicycle steering rack with crown and part of the fork); 12 - steering tower (steel, sheet S4); 13 - mounting steering tower (type M16); 14 - Fastening the springs of spring and springs of the lever to the ski (bolt M5 with a secret head, 7 pcs.); 15 - lever sleeve (steel pipe with a diameter of 30 mm); 16 - Slip bearing (Kapron sleeve, 2 pcs.); 17 - Stand bushing (steel pipe with a diameter of 30 mm). On the top view of the detail 11, 12, 13 of the swivel fist are not conditionally shown.

Snowmobile racks can be made of 3x3 cm. They are connected with each other with steel jumpers. As a result, there is a relatively not large portal. To create a platform, you need to take a sheet, 2 mm thick and connect it with the portal and middle right side vehicle elements. This venue will serve as a place for fastening a gearbox and chain transmission shaft.

On parts of the rear portal and the middle of the snowmobile should be formalized not a great place for the design of the seating.

The front of the frame and traverse of the front bridge are connected by the beam. As a beam, there is a conventional water pipe, with a diameter of 1.5 cm. At the end of this pipe, the steering ski bushings are attached with the help of welding, and the center is mounted. The rack will serve as a support for the motor subframe.

Special attention should be paid to the points of attaching racks. For greater reliability, the attachment points are amplified by steel brazers, 2 mm thick. This approach will strengthen the vehicle and make it more reliable and durable.

Caterpillar

Snowmobile frame with caterpillar block: 1 - rear side of the spar (steel sheet S2, with flames, 2 pcs.); 2 - tensioning device (4 pcs.); 3 - rear portal (corner 30x30); 4 - middle side of the spar (corner 50x63, 2 pcs.); 5 - Bracket-plug Installation of the axis of support rollers (steel sheet S2, 10 pcs.); 6 - average portal (30x30 corner); 7 is a platform for fastening the gearbox of a power unit and an intermediate shaft-mud (steel sheet S2); 8 - Kosinki (steel sheet S2, 4 pcs.); 9 - front portal (30x30 corner); 10 - front component spar (steel sheet S2 with flames); 11 - axis of tension gears; 12 - Tension gear wheel caterpillar (2 pcs.); 13 - axis of support rollers (steel, circle 10, 5 pcs.); 14 - Mounting axis (nut M10 and spring washer, 20 pcs.); 15 - remote sleeve (duralum tube); 16 - rink (18 pcs.); 17 - Bearing node (4 pcs.); 18 - drive gear wheel caterpillar (2 pcs.); 19 - drive shaft of the caterpillars; 20 - drive star of the drive shaft (driven asterisk 2th degree of chain transmission), z \u003d 18; 21 - the sleeve of the swivel fist of the steering ski (pipe with a diameter of 30 mm, 2 pcs.); 22 - front axle beam (pipe with a diameter of 30 mm); 23 - Kosinki, 4 pcs.; 24 - submool rack (pipe with a diameter of 30 mm); 25 - Bandage Roller (Rubber Ring, 18 pcs.).

You can take caterpillars from the old "Buran" to build a mini-version of the snowmobile and modify it by rooting almost an entire meter. The gears can be performed from a capron leaf, 1.5 cm thick.

Drive shaft

The drive shaft of the caterpillars (tensioning shaft is the same, only pos.4, replaced by position 1): 1 - left (along) tip (steel, cylinder 22); 2 - shaft (steel pipe 0.28x20; 3 - flange of fastening of the gear wheel to the shaft (steel sheet S4, 2 pcs.); 4 - right (along) the tip of the shaft (steel, cylinder 29); 5 - gear wheel drive wheel (2 pcs.); 6 - spar frame, 2 pcs.); 7 - Bearing housing cover (steel, 2 pcs.); 8 - Bearing 80204 (2 pcs.); 9 - Bearing hull (steel, 2 pcs.); 10 - shaft drive asterisk; 11 - Fastening asterisks to the shaft (M12 nut with wide and spring washers); 12 - sword (steel 20); 13 - seal (felt, 2 pcs.); 14 - fastening the bearing housing to the spar (bolt M6, with Grover 4 sets); 15 - Fastening the bearing housing to the spar (bolt M6 with a spring washer, 4 sets).

The drive shaft is made of steel pipe, a diameter of 1.4 cm. Special flanges are attached to the shaft, to which the gears are attached. At the end of the drive shaft, through welding, the tip-axes are mounted. There should be a place for the installation of bearings on the tricks.

Engine

This unit is considered the most responsible snowmobile mechanism. Compared to other elements of the design, such as a tire or chain, the engine must work properly and without it, no snowmobile will not move. Therefore, the long-term efficiency of the device will depend on reliable and trouble-free operation of the engine. If you want to install the engine from chainsaws, imported production, then you can purchase a used "Shtil".

Another important structure of the design, on which the trouble-free operation of the snowmobile depends, the gearbox is considered.

Asterisk

Immediately, the fact that the right tip has a key groove for installing and fastening a chain-transmission sprocket. This is an asterisk of a crawler shaft, which is securely attached using the nut. To make the fastening it is possible, the corresponding thread is cut on the tip.

The tip of the stretch shaft has the same dimensions, and the fastening of the structural elements is carried out similarly to the attachment of the stars of the caterpillar shaft.

At the first stage of the transfer, an asterisk with the highest gear ratio (by the number of teeth) should be. On the engine chainsaw "Ural" you can count 38 teeth.

Steering

On the homemade device You can install the steering wheel of any design and even from the bike. In this case, it is very important to take the steering wheel control of engine turnover. To hardly bother, it is better to use the steering wheel from the moped, a scooter, etc., where the engine power control mechanism is already provided. This will make the design more reliable and convenient to manage.

Brake system

Usually, such a vehicle has no brake systemYes, and it is not obligatory, since the snowmobile does not develop high speeds, the more homemade. Although, if you seriously approach this problem, you can build a primitive braking device.

Immediately, it is worth paying attention to that a homemade design, so that it is neither of themselves, it is unlikely to be able to register (legitimize) in the relevant authorities. And therefore:

1. According to the law, homemade Snowmobile Does not refer to the category of vehicles. Therefore, its further use, as well as responsibility for the consequences, fall exclusively on the person who did it. It is better if it is operated somewhere in the outback and do not come across the eyes of the relevant services.
2. Snowmobile and floating all-terrain vehicles are absolutely different devices, although they have a certain similarity.
3. Since the engine has little power, then transport vehicle Loads are not desirable. It is better to move on it alone.
4. For movement at night, the lighting (headlights) can be installed on the snowmobile. This will increase the functionality of the device and comfort when moving.

Conclusion

Due to the fact that most people do not have the skills of self-making any structures, they believe that it is quite difficult to collect a snowmobile. And if you manage to build something like a snowmobile, he is unlikely to go, and if he goes, it will stop very soon. And it will not be like a snowmobile at all, but on the pile of spare parts collected together. Fortunately, this is not as well as with the proper approach and the level of fantasy, you can collect a similar structure from the submitted means, which at least "PRUD" in any garage. And if there is at least any experience with these spare and infirm materials, the task is simplified at all. The principle of desire is already beginning to act here and if it is not, it is hardly possible to collect anything at all, not to mention a snowmobile.

The fact that the problem is current in our time is not just a statement, but a conviction based on problems today's day. Unfortunately, the state does not go to a meeting with wide sections of consumers, but took a course on the production of only expensive equipment designed to implement the consumer with money.

Snowmobile do it yourself - video

There are many ways to diversify the winter entertainment of the child, make them more diverse and fascinating. But one of the most favorite programs of the pastime remains the use of various "vehicles" to conquer snow spaces.

Even the simplest "ice plants" can lead to the delight of babies and schoolchildren. And if the children's snowmobile will be introduced into the game: a snowmobile-quad bike on gasoline, made by careless parents with their own hands or bought in the store, it will definitely not be the end. Sure, speed mode For such a device and its technical characteristics are very different from those that are relevant for adult equipment.

Popular homemade models for children look quite stylish and attractive, if you attach a certain effort to create them. And among the purchased options, you can find solutions, attractive for kids, and teenagers. It would seem to choose optimal option Will not work. But in practice, finding the best solution is quite difficult.

What it is?

Technologically, it is also possible to distinguish certain, very important, moments:

• the presence of the height adjustable;
• simplicity, security and functionality of management;
• soft and smooth operation of the brake mechanism;
• limited power of the motor, not giving a lot accelerate;
• high stability associated with the location of the center of gravity in models at low height from the ground level.

Snowmobile for a child as a whole is similar to another popular winter device - snow scooter. Only instead of the mechanical driving force here uses an electric or gasoline engine. In addition, similar models are actively used various options Control, and more reliable brakes that can easily provide quick stop.

Snowmobile itself is a vehicle intended for movement in the snow. It is equipped with special seasons providing stability when moving on snow tracks.

Children's snowmobile techniques come on sale are usually complemented by an external controller - a control panel - able to cope with the stop of technology in emergency situation. Such parental control is very useful at the initial stages, when the child only masters new equipment for itself.

Adjusting the steering wheel in children's models is provided on an individual basis, which greatly facilitates the use of equipment for riding babies of different ages.

Views

All existing options for snowmobiles manufactured for children can be divided into several categories, according to their technical characteristics and design features.

• Children's snowmobiles with electrical drive. Equip rechargeable batterywhich is capable of supporting the performance of technology for a long time. They are environmentally friendly, low noise, safe for children of different ages. When storing at home, this technique does not highlight into the atmosphere harmful substances. The battery is easy to replace after use. Such models practically do not require complex or expensive service.

• Quad bikes all-terraines - Universal solution for any age. Recommended for use in year-round mode. Hybrid solutions are equipped with a single chassis with interchangeable modules. For example, the configuration may include wheels for summer ride. Rear caterpillars exist for use as a all-terrain vehicle. There are special skis needed during operation in a snowmobile mode. Hybrids are produced mainly in gasoline versions.

• On gasoline. Equipped with modern and reliable gasoline engines, non-volatile, but cannot be called environmentally friendly. Such models are recommended for the use of adolescents, equipped with rather powerful motors.

But you can find and the most simple optionsSafe even for younger schoolchildren.

Consider some of the features of rechargeable and gasoline models in more detail. Electric, environmentally friendly models are most often developed independently or present in the form of a concept. Can be made limited series. Batteries in them are usually powerful, similar to the fact that they are installed in the car.

Unhaperant solutions used in such an energy carrier minimize losses associated with electrolyte evaporation, which also contributes to the essential improvement in the overall indicators of environmental and safety equipment.

Gasoline children's snowmobiles are widely represented on the market in versions from well-known companies specializing in the production of motorcycles. Such models are equipped with two-stroke or four-stroke engines, easily and quickly warmed up even in the cold. Maintainability of the equipment, simplicity in service make them good choice For winter skating.

For gasoline snowmobiles, children are characterized by the use of one of two options for cooling systems: air and water type. In the second case, the environment is acting as a source of a cold supply, namely: dropped snow.

When choosing fuel, it is necessary to give preference to unleaded variants that can significantly extend the resource of the motor.

How to choose?

Choosing a children's snowmobile for a grown chad - a task not from the lungs. But it will be quite solved if you start from the very beginning select the appropriate model based on the following parameters.

• Age of the child. For kids, the simplest models are manufactured with the minimum possible development of speed. The main audience, which is interesting to such a technique - younger schoolchildren and teenagers.

• Constructive features . High-speed models for extreme trips can be equipped with additional security system elements. Most common options use modern and reliable manual brakes.

Engine operation blocker can be external. In this case, the stop is performed through the signal on the remote.

• Features of the design of skis. Material for their manufacture should be quite flexible and elastic, but at the same time strong, able to withstand any operating conditions. Pay attention to the presence of a rotary element. In cheap children's models, manufacturers often save on it. The depreciation system installed here must withstand significant loads without visible effort.

• Corps material. It is worth avoiding the use of excessively fragile elements. Thus, polyurethane parts under negative temperatures turn out to be fragile.

The frame base must be metallic, sustainable to external damage and shock loads.

The presence of reflective elements is additional advantage In the construction of a motor vehicle.

• Producing country. The most reliable, popular and modern species Technicians are produced in the USA and Japan. But you can find more budget proposals.

Manufacturers

Among all the available brands are relevant, models of a number of large and well-known manufacturers are considered. Consider some models more carefully.

Yamaha.

This Japanese manufacturer specializes in creating sports and highway motorcycles, but quite successfully copes with the manufacture of reliable snowfare.

Most Popular Model - Yamaha SRX 120having gas engine. Snowmobile is equipped with a single-cylinder engine power 3.5 horsepower, has excellent performance. The package includes an emergency shutdown module. Technique weighs 76 kg, it is quite placed in the car trailer, reliable and maneuveran.

Snow Fox.

The miniature solution and the budget price make this four-cell unit with a good choice for mastering the child of the first snowpad tracks. The design of the equipment is standard - with two resistant front skiing and rear tracked conveyor.

Small snowmobile weight - only 37 kg - makes such a choice optimal for family walks. The budget cost provides all the possibilities for purchasing a fashionable device for a child.

Arctic Cat F120

Model, famous for ease of use. Among the options here have heated steering handles, emergency braking system.

The model is quite massive and stable. It has a weight of 75 kg, a comfortable landing, protected from external influences case. Motor single-cylinder, with a capacity of 3.8 horsepower.

Taiga RM Lynx

Manufactured russian manufacturer Children's snowmobile Taiga RM Lynx has all the advantages of modern motorized technology. It is compact and easy to operate. Speed \u200b\u200blimit set at the limit of 13 km / h. In addition, it completely copies a similar adult model externally. This feature is a very good argument for boys who wish to resemble their parents. The package includes a single-cylinder motor with a capacity of 6.5 horsepower.

What kind of snowmobile version to choose for a child - parents themselves solve. Almost all serious and modern techniques, regardless of the manufacturer's country, today costs more than 1 thousand dollars. Models are cheaper significantly inferior to their expensive counterparts and in class, and in reliability, and to the degree of security.

How to make your own hands?

If the child wants to get his own snowmobile, it can be done with his own hands. The homemade option can be constructed from remedies.

Before proceeding with work, you need to carefully examine the characteristics of products intended for children. In particular, it is not necessary to use too powerful models of engines - take into account the age of the child, its growth and weight characteristics.

What is the difference between snowmobiles for adults and for children? The main differences include the sizes of technology and power, which is significantly lower in children's models. In addition, the principle of operation and the design of children's snowmobiles is many times easier. When developing children's snowmobiles, a lot of attention is paid to safety measures. These include the ability to turn off the engine remotely, as well as often install the speed limiter. That is, the child will not be able to develop the speed more than they want the same parents, pre-setting the restriction. As a rule, on most models maximum speed does not exceed 13 km / h. Also that the child is being protected as much as possible, manufacturers install a "security lace". It is necessary for the child during a fall from the snowmobile stopped the operation of the engine. Front skiing in children's snowmates is wide, to prevent eyelashing and as a result of injury.

To date, there are two types of children's snowmobiles: electric and gasoline. This article will be discussed about gasoline, as they are the most popular. Only a gasoline snowmobile will allow you to feel the child that drive and the influx of adrenaline from driving on a real adult technique, well, only smaller sizes.

Gasoline engines are 4 and 2-stroke. The first are characterized as very reliable aggregates with a large reserve of the engine test. During operation of the 4th tracked Engine Forms a minimum of noise. Also, gasoline consumption is significantly lower. In turn, the two-stroke productive elements have a small mass and dimensions, very compact. Does not arise difficulties in the case of operational or repair work. Two-stroke engines No need to prepare for work (warming).

The cooling system can be two types: air and liquid. They both have their own advantages and disadvantages. Aerial system It is characterized as very simple, but sometimes the engine overheating is possible due to improper handling. Water cooling is more reliable, engine overheating is minimized. Since cooling in this case is due to snow, overheating occurs due to the lack of loose snow.

About the fuel system. There is an injector I. carburetor system. The so-called injector uses less gasoline, it works reliable, emission exhaust gases less. But if they arise any problems with the injector, repairing in the field is quite difficult.

Children's snowmobile do it yourself

Today it is not difficult to find a suitable model of a snowmobile, which will definitely like your child. But, the main difficulty when buying a children's snowmobile, which parents face are the price. The cost of this transport is very high. Therefore, the fathers have an idea of \u200b\u200bthe production of a homemade snowmobile.

Pluses of a snowmobile, which is designed by hand:

1. Cost. The manufacture of a homemade snowmobile will go much less moneyrather than factory equipment.
2. The ability to make a snowmobile dream of your child (desired design, power, etc.).
3. High reliability. Each parent wishes to her child only good, so the snowmobile will be developed qualitatively. In turn, not each manufacturer draws attention to the level of security in the pursuit of an increase in cash flow.

The main details that are necessary for the development of a self-made snowmobile are: power unit (engine), fuel tank, frame, caterpillars, skiing, control and seat element. In addition, there must be a drawing in which the assembly of all parts in one whole will occur. First, weld the frame from the pipes and corners, then it is connected to the steering mechanism. Next will follow the installation of the engine. The location of the carburetor should not be distant from the tank for fuel. After installing the engine, tank and installation fuel system Go to the caterpillar installation. Caterpillar can be purchased separately or to make it yourself, after reviewing the learning video. The slave bridge is installed in the back of the frame, the leading bridge in the middle of the equipment. The final stage includes the connection of gas and brake cables.

Price for children's snowmobile on gasoline

The ultimate cost may fluctuate depending on technical characteristics, quality and reliability of assembly, functionality. For example, a model from the Japanese manufacturer "Yamaha SRX 120" will cost about 250 thousand rubles. The domestic "Taiga Lynx" from "Russian mechanics" has the cost of 105 thousand rubles. Chinese-made snowmobiles are estimated at 70-90 thousand rubles.

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

Homemade for movement in the snow are diverse appearance, sizes, layout, power, and even on the principle of movement. But in each variety there are nodes that ensure the properties necessary snowmobiles, namely:

1. Do not fall into the snow.
2. 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 construction - dimensions, weight and high degree The vulnerability of the wheels, but on the popularity of the high-speed homemade pneumatics it 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 B. 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.

Snowmobile S. car Engine Designed for long-lasting 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.
