Do-it-yourself pneumatic tubes. How to make a pneumatic duct with your own hands? How to make a pneumatic drive from a walk-behind tractor, instructions, photo Do-it-yourself pneumatic drive on one wheel

Much time was devoted to work on this amphibious all-terrain vehicle, and I want to tell you about it only now, when all possible and impossible tests have already been passed. As I planned, the car was assembled according to the 4x4 scheme.

Frame

For the manufacture of the frame, pipes with a size of 50x25 and a diameter of 16 millimeters were used. At the same time, thicker pipes were used for the main elements, and smaller ones for additional parts. In addition, an angle of 25x25 and 35x35 millimeters is used in the frame design.

Structurally, the frame consists of a central box, body kit parts and wheel arches frames. The central box is a waterproof construction with a 35x35mm corner frame. In the front and rear parts of the box, the role of the walls and the bottom is played by three-millimeter steel sheets, and the middle part is made of three layers of fiberglass impregnated with epoxy glue. This is done to make the box buoyant (after all, the car was conceived as an all-terrain vehicle). The wheel arch frames, steering column spars and body parts are attached to it.

Self-made all-terrain vehicle frame

Inside the box are the gearbox, transfer case, main gear housings of the front and rear axles and cardan shafts. This minimizes the risk of damage to transmission components. Hatches in the bottom of the hull provide unhindered access to the units. The bottom of the body is attached to the upper ribs of the box for welding.

Body

Externally, and inside too, the body is made in two volumes. The first volume is reserved for the engine compartment, while the second volume houses the cockpit and luggage space. It seems to me that this arrangement is most suitable for using the machine in difficult road conditions.

General scheme of the all-terrain vehicle

The basis for the manufacture of the engine compartment and the cockpit was the old Zaporozhets 968th model. The front half of the body was cut off from it, which went into action. I acted differently with the luggage compartment, the lower part of the sides was formed by the doors welded together from cars from the landfill. For the manufacture of the upper part of the sides and the roof, plywood was used, followed by sheathing on both sides with leatherette. External dimensions of the body are as follows: length 4 meters, width 1.5 meters, height on the roof of the luggage compartment 1.3 meters.

I originally designed a homemade SUV with buoyancy. The problem of ensuring thermal insulation and buoyancy was solved very simply, all the existing voids in the elements of the cabin, as well as in the sides of the body, were filled with pieces of foam that were fitted in shape. There are enough cavities, both in the cockpit and in the sides, so that buoyancy was provided with a margin. Speaking of insulation, at one time they never got around to making normal heating of the cabin, so heating is possible only by the flow of air from the engine, this is where the insulation between the walls of the body and the cabin played its role. Even in frosty weather, the car is warm enough. Perhaps the fact that there is only one door in the car also played a role. It is located on the rear wall of the body and opens upwards. When open, the door is held by two springs from the front fork of the MMVZ motorcycle. Door dimensions 990x655mm. The doorway is equipped with an airtight seal and the door itself has a small window.

In the cabin, there are seats only for the driver and passenger, behind them there is a free space measuring 1.7 by 1.35 meters. In such a space, two lying people, or a load of the appropriate size, are easily accommodated. The side windows of the body are equipped with sliding vents, the windshield is from the same donor as half of the body. Future plans include a sunroof to provide better ventilation. In addition, it can be used as an emergency exit.

Perhaps someone will find such a body arrangement rather strange (due to the fact that there is only one door available), but I was guided, first of all, by the requirements for the rigidity of the entire car as a whole. After all, the more doorways in the body, the less rigidity and strength it has. Is not it? And when operating a car in extreme conditions, body rigidity is, in my opinion, one of the most important requirements for a car. The tightness is also important - quite often you have to wade through water bodies. Of course, my car did not turn out to be a semblance of a GTS of an all-terrain vehicle, but I am satisfied with the level of buoyancy and cross-country ability.

Mechanical part

In the engine compartment, located above the frame, there is an engine from the same Zaporozhets, which served as the source for the body of the all-terrain vehicle. True, in order to work in the new conditions, it had to be deployed "backwards". The torque from the engine is transmitted to the Zhiguli gearbox. In order to install it, it was necessary to make an adapter that simultaneously acts as a clutch cover and has holes for attachment to the engine and box.

All-terrain vehicle transmission diagram

The mechanism of the self-made transfer case is based on the differential from the Zhiguli rear axle. To do this, it was necessary to grind the differential housing in order to fit a glass with a gear rim on it. Initially, there was no crown on this glass, I had to cut the teeth myself. Tooth module 3.5. For such a module, I had to order gears for the rest of the filling of the distribution box. The collar at the end of the glass is intended for attaching the rim of the gear wheel, which is pressed onto the differential housing. All these parts are twisted with screws, the diameter of which is equal to the diameter of the standard screws, but the length is slightly longer. The box body is welded from 4 - 6mm thick metal. There are no special holes for changing the oil, I use the upper and lower holes for the cover bolts for these purposes.

The engine, gearbox and transfer case, as well as the gearboxes of the front and rear axles, are located along the axis of symmetry of the vehicle. The gas tank (I don't know from what), which holds 35 liters, found its place in the rear of the car under the bottom.

Chassis

All steering assemblies were used Zhiguli (the steering wheel was taken from ZAZ).

The front and rear suspensions of the machine are independent, spring-loaded with shock absorbers. The rear wheels are suspended from trailing arms in a traditional manner. The wishbone front suspension is a little more complex, with a transverse spring in the design for reinforcement. The spring is made up of three "Muscovite" sheets. Front and rear wheel drives are identical in design.

Chassis

Cuff with boot

The entire design and layout of the all-terrain vehicle were initially thought out as an option with replaceable wheels. I must say that changing wheels is very useful when operating the car in different seasons. For example, in the summer the car behaves perfectly on the modified wheels from the "UAZ", and in the cold season it changes its shoes into homemade low-pressure pneumatics, and feels great on ice and snow. Modification of the wheels from "UAZ" was reduced to cutting out a section of the disc and welding a homemade seat with holes. To install homemade wheels for the winter, the fenders are removable (otherwise they interfere with large diameter wheels).

After replacing one type of wheels with another, the dimensions of the car and the ground clearance change accordingly. The difference is 130 millimeters. So, on pneumatics, the clearance is 500 mm.

Conclusion

In general, I was pleased with the car, there were no serious complaints. The assembled all-terrain vehicle on a pneumatic drive fully met my expectations and efforts for its manufacture. The only inconvenience, in my opinion, is the need to recalculate the speedometer readings when driving on pneumatics (multiply by 1.5). By the way, on pneumatics in a low gear, the car easily accelerates to 60 kilometers per hour.

Any man who lives in rural areas all year round has thought more than once about purchasing an all-terrain vehicle. It is especially useful for fishermen, hunters, since its characteristics allow to overcome almost any obstacle in the form of holes, off-road, spring thaw and ice. You will need a minimum amount of money and time - you can easily make a frame and wheels for a pneumatic drive for a walk-behind tractor with your own hands!

Homemade all-terrain vehicles on a pneumatic drive from a walk-behind tractor

Homemade pneumatic tubes on low-pressure tires are popular due to their versatility and strength: both in summer () and in winter () such a unit will always be on the move.

The design of the self-made pneumatic duct is based on the main traction force - the walk-behind tractor. A walk-behind tractor is an engine with an existing rotary element that allows you to use attachments - a cultivator, a rotary mower, a plow and others. You can often find pneumatics with a trailer - the power of a middle-class unit is enough even to transport a haystack.

In any case, there is no point in buying an expensive mechanism, since the pneumatic duct will still be modernized for specific needs.

Engine selection

The power of the homemade motor on the pneumatic drive determines the performance of the walk-behind tractor, and, therefore, the higher the power, the more efficiently the pneumatic drive will work. But there is a downside to the coin: with high power, fuel consumption also increases, and this is not practical if you live far from a gas station. If you plan to use the air vehicle only in the summer, then it is better to stay on a budget model that has a two-stroke engine. It starts up quickly and has a simpler design.

For winter fishing or hunting, only a four-stroke is suitable.

Thanks to the step-by-step stages of switching on, the four-stroke walk-behind tractors warm up gradually, which significantly extends the service life of the pneumatic drive.

Required tools and materials

Since it is necessary to weld metal parts together, then you definitely cannot do without a good welding machine!

The list contains the following tools:

1. Hammer;
2. Screwdriver;
3. Metal nippers;
4. Drill with drills for metal;
5. Grinder with a circle for metal;
6. A set of 10 or 12 car keys.

The next step is to purchase the missing materials for the homemade pneumatic drive:

1. Motoblock: you can use the engine from hybrid agricultural equipment;
2. Rims from a car or motorcycle: they are made of iron, so buy anti-corrosion paint; or homemade / modified depending on the needs;
3. Cameras GAZ or others (for example, aviation or from trailed agricultural machines);
4. Pipes: any pipes and even their cuttings will do;
5. Steering column: it is advisable to purchase the model as new as possible, since the quality of control of the pneumatic all-terrain vehicle depends on this, or use a car rack;
6. Hubs: suspension elements must be selected with the least wear, you can use automotive;
7. Metal corners;
8. Fasteners (bolts, screws);
9. Reinforcement or wire.

Assembling the pneumatic duct on low pressure tires

Approximate drawing of a pneumatic duct

Before you start assembling the pneumatic drive from the walk-behind tractor with your own hands, make sure that all electrical components are compatible with each other. Be sure to draw up a detailed plan for the implementation of the project, and also schedule the assembly process in stages.

Observe safety precautions when working with a welding machine. Always wear a mask to protect the mucous membranes of the eyes and cotton gloves.

The installation process can be roughly divided into the following stages:

1. Preparation and cleaning of the workplace from excess debris and tools.
2. After determining the dimensions of the supporting frame, cut the pieces of pipes with a grinder, and then weld them into a single structure.

1. Next, put the cameras on the discs and secure. Check the tightness of the joints by pumping them with air.

1. Pay particular attention to the design of the air travel steering system: it must be free from damage and obvious signs of wear. Install the steering and secure to the frame with a galvanized bolt.
2. It's time to connect the drive! Screw on the wheels and attach the brake pads to the metal axle.
3. Installation of electrical circuits.

1. After all the manipulations carried out, proceed with the installation of the walk-behind tractor. For stationary use, bolt securely. Now you can understand how your invention will work.

For durability and an attractive appearance of the pneumatic drive from the walk-behind tractor, the finished structure should be painted with a special protective paint for metal.

DIY pneumatic wheels

Wheels can be of the following types:

1. Tire with protectors. Tires from a tractor or truck will do. They have a deep pattern that increases the cross-country ability of the home-made pneumatic all-terrain vehicle. Often, DIYers lighten the tires by increasing the tread pattern by cutting off excess rubber on the outer layer - such wheels are called "peeling" or "peeling".

1. Car chamber filled with air - low pressure tires. To increase the adhesion of the air suspension with sand, ice, mud and water, metal chains, rings or belts must be attached to the cameras - this will give the structure additional rigidity when driving, as well as increase maneuverability when cornering.

1. Combined, when tires are used together with low pressure chambers.

For wheels, choose galvanized metal alloy wheels, despite their cost - they will last much longer than iron wheels and will fully pay off in a few years.

To distribute traction more smoothly and evenly while working on the pneumatic drive, install a four-speed gearbox from Zhigulenk. Thus, you will be able to adjust the speed and significantly save fuel consumption.

If you plan to use the air suspension in the dark, be sure to install the headlights in the front of the frame: build a box where the generator and battery will be installed.

Buying a pneumatic drive is an expensive pleasure that not everyone can afford, but almost everyone can assemble a homemade pneumatic drive from a walk-behind tractor and improvised materials, while saving a lot of money!

Motoblocks are the favorite technical devices of many farmers, so it is not surprising that when using a constructional imagination, you can transform the unit and create an all-terrain vehicle, a karakat, a snowmobile, a pneumatic vehicle, an ATV and a swamp vehicle on its basis. Today we will consider ways to expand the functionality of the device without special financial costs and contacting specialists.

We create an all-terrain vehicle from a walk-behind tractor with our own hands

It should be noted that the very concept of "all-terrain vehicle" means a vehicle with high cross-country ability. An important fact: the all-terrain vehicle, the karakat and the pneumatic vehicle, the swamp vehicle are synonymous with only a few minor modifications. If a person manages to create a homemade mini-all-terrain vehicle, he will receive a real masterpiece that will become his pride.

Before starting construction work, it is necessary to decide whether the device will be on tracks or on pneumatic wheels. An important point: it is much more difficult to create a tracked unit, and it requires special knowledge and physical effort to operate it. A powerful engine should also be prepared for installation. It doesn't matter what it will be, diesel or gasoline, the main thing is that the part is powerful and equipped with forced water or air cooling.

The working process

1. First you need to choose a base for the design. A frame from an old URAL or IZH motorcycle can be used. Thanks to such options, the car will be more maneuverable and will be able to easily overcome any obstacles;
2. The next step is to create the suspension and rear axle. Independent front and rear suspensions are connected by means of a rack, a steering bushing and a mowing bar;
3. The wheels for mounting should be taken from powerful trucks. Excellent, but not mandatory, options will be cameras that differ in low pressure (from KamAZ and URAL cars). Having made the right choice, the driver can be confident in his own safety and enjoy easy driving;
4. Mounting the motor is one of the most serious steps in creating an all-terrain vehicle based on a walk-behind tractor. Finally, the owner must securely attach the engine, clutches, brakes and exhaust system.

Only after a thorough check of the newly made cross-country vehicle, you can start testing and further operation.

Caracat from a walk-behind tractor: specificity

In fact, the karakat performs almost the same tasks as the all-terrain vehicle, only its peculiarity is manifested in large wheels tightened with strong belts. At first glance, such a device may seem rather cumbersome and awkward, but in fact, the specified transport is quietly operated on terrible roads at speeds up to 70 km / h.

How to create powerful wheels with your own hands?

There are 4 ways:

1. The first method is relatively simple: 2 sheet metal discs are used, which are attached to the bushing. After that, the camera is put on, fixed with sections of a special conveyor belt;
2. The second involves securing one disc to the hub and attaching a jumper. Then side rings must be welded to them;
3. The third option is very similar to the second, only a pipe or sheet metal spoke is used for the central disc;
4. The fourth principle involves mounting two discs on the hub, which are very similar to wheel discs from a scooter.

Thanks to the strong suspension, which can be easily welded from steel pipes and connected by hinges, the karakat can withstand incredibly heavy loads. It's just that it is somewhat more difficult to control such a unit, since often the design is based on a conventional worm gear.

In order to competently make a karakat from a walk-behind tractor with your own hands, you can use the above tips regarding the all-terrain vehicle, and familiarize yourself with the drawings on our website.

It will not be difficult for craftsmen who understand the mechanical and structural features of motoblocks to create a truly high-quality karakat, which will become a real assistant for fishing trips, mushrooming, hunting, etc.

Features of creating a homemade snowmobile from a walk-behind tractor with your own hands

Many craftsmen know that such an agro-industrial machine as a walk-behind tractor can easily be transformed into a snowmobile, which allows you to successfully move off-road even on the most snowy days. Moreover, the process of alteration itself is quite simple and straightforward.

The main thing is to choose the right engine. Experienced owners of such "assistants" are advised to give preference to the device that has manual control and a towing device. In most cases, a class of motoblocks is used, the design of which provides for the use of a 4-stroke 1-cylinder gasoline engine with air cooling.

Before starting the process of working on a future snowmobile, you need to prepare:

• powerful wheels (or tracks with snow tracks);
• frame;
• power unit;
• drive unit;
• runners;
• shock absorbers;
• steering column.

Some parts can be created by yourself, and some can be purchased. For example, a frame will fit from an old motorcycle, and longitudinal tubes of frames from old bicycles should be used as swivel ski racks.

How to make a snowmobile from a walk-behind tractor: step by step instructions

• To begin with, the engine is installed from the walk-behind tractor on a caterpillar drive;
• Then two rods are attached to it, joining the transverse beam (where the steering wheel and skis are already fixed);
• The front pillar and seat are mounted in the space between the two rods;
• Now the tracked propeller needs to be attached to the specified crossbeam;
• All other parts should be attached with pins and bolts.

The result should be an excellent motorized vehicle capable of transporting a person (and a small load) in difficult weather conditions.

We get acquainted with the pneumatic crawler from the walk-behind tractor and the swamp crawler from the walk-behind tractor

As mentioned earlier, the pneumatic vehicle and the swamp vehicle are somewhat modified analogues of the all-terrain vehicle and the karakat. The first option is considered a simple mobile vehicle, which appeared in the 60s and in modern modifications is supplemented with 3-6 wheels for better cross-country ability.

A feature of both a pneumatic drive based on a walk-behind tractor and a swamp-going vehicle is the operation of special low-pressure wheels. The fact is that in this case the tires are lightweight, flexible and exert little pressure on the ground. Together with a large rolling radius, the device is characterized by passability and endurance.

The breakaway pneumatic vehicle and the swamp vehicle are created according to the same scheme as the all-terrain vehicle, therefore, many experts often use three terms in one context. On our site, everyone can find a video with the practical use of devices and evaluate their similarity with the indicated alteration options.

Learn to create an ATV from a walk-behind tractor

Curious, could the designers of motoblocks imagine what folk craftsmen would turn their offspring into? Unlikely! Moreover, the masters are not going to stop there, and the ATV created on the basis of the walk-behind tractor is a vivid proof of this.

It differs from a standard motorcycle by the presence of four wheels, allowing you to easily drive through the most mountainous areas. The ATV is also known for its relative safety, because in the event of falling into a hole in the road, it is much easier to fly out of a two-wheeled motorcycle than from a four-wheeled one.

General stages of transformation of a walk-behind tractor into an ATV

• Expansion of the wheelbase;
• Competent arrangement of the frame;
• Fitting suitable wheels.

Detailed stages of transformation

• To begin with, you should spread the wheels using special rates that are turned on a lathe or purchased in a store;
• Then you need to take care of creating the frame. These parts are often "borrowed" from a bicycle or motorcycle, but the possibility of welding them from classic water pipes is not excluded;
• Now you should attach this very frame to the walk-behind tractor for the pivot hinge using two pins;
• Then you need to deal with the wheels. Naturally, car wheels for rubber (with a low profile) are considered as the best option. They are distinguished by a fairly wide stock and an excellent rubber chamber that will fit perfectly to them;
• Cameras should be chosen from trucks, then there is no need to doubt the practicality and endurance of the device.

Thanks to this simple method of alteration, you can get an excellent ATV that does not need a knurled road and is not afraid of sharp turns and slopes.

In total, it can be noted that with additional tools, materials, drawings, video tutorials and other things, the walk-behind tractor can be completely retrained and "breathe new life into it"!

It is quite possible to make pneumatic passages with your own hands on low-pressure tires. These machines are popular for their strength and versatility. This technique proved to be excellent in the summer heat and on snowy roads. As a basis for, you can use a walk-behind tractor. The unit is a power unit with a rotating element designed for aggregation with various attachments. Such a device is able to transport cargo on a small trailer.

Engine

The power indicator on a homemade unit determines the performance of the selected walk-behind tractor. The higher this parameter, the more efficiently the equipment will function. On the other hand, high power leads to increased fuel consumption. If the owner lives in the outback, far from the gas station, this aspect will play a significant role.

Those users who plan to use the equipment only in the warm season are advised to opt for a budget modification with a two-stroke engine. It is simpler and quicker to start. For fishing and hunting in winter, a four-stroke power unit will be the best option. Such variations warm up more slowly, providing a longer engine life.

Tools

To make pneumatic tubes with your own hands, you will need a set of certain tools and devices. This list includes the following items:

• Welding machine.
• Hammer, screwdriver set.
• Cutters for metal.
• Drill and grinder with attachments for metal processing.
• A set of car keys.

From the materials you will need the following things:

• Motor from a walk-behind tractor or identical agricultural equipment.
• Iron motorcycle or car rims on wheels, which should be treated with an anti-corrosion coating.
• Cameras from aviation or
• Cutting pipes.
• Steering column. It is advisable to purchase this part in a new form, since it will be responsible for the quality of control of the machine.
• Suspension elements (car hubs can be used).
• Metal corners and fixing accessories.
• Wire and fittings.

Do-it-yourself pneumatic drive from a walk-behind tractor: assembly

Before assembling the unit in question, you must make sure that all electrical connectors and contacts fit together. It is necessary to draw up a schematic plan or drawing of the proposed apparatus. It is also necessary to develop stages of work and observe safety precautions.

The installation procedure is divided into the following stages:

1. Preparation and cleaning of the workplace.
2. Determination of the dimensions of the base frame and cutting of pieces of pipes of the desired length, followed by their joining by means of welding.
3. Installing prepared chambers on disks and checking them for tightness of joints.
4. Steering assembly. Particular attention should be paid to the quality of the column, its absence of damage and correct fixation with a suitable bolt made of galvanized steel.
5. Connecting the drive by installing wheels and brake pads on a metal axle.
6. Installation of electrical circuits.

After performing these manipulations, you can start installing the walk-behind tractor with your own hands on the pneumatic ducts. The base must be securely bolted in place. In order for the machine to acquire an attractive appearance and obtain a longer service life, it is advisable to paint the body and open parts with protective materials.

Wheels

In the manufacture of the equipment in question, it is better to use parts from a truck or tractor with wide treads as wheels. Such modifications are distinguished by a deep pattern, which provides high cross-country ability. Alternatively, you can lighten the tires by eliminating excess rubber on the outside. Such "homemade products" are called stripping.

A self-made pneumatic drive from a walk-behind tractor can be reinforced with low-pressure tires. They will provide traction on surfaces covered with ice or snow. To do this, you will need to adapt metal rings or chains, which will create additional rigidity when driving and improve the maneuverability of the vehicle.

Peculiarities

Sometimes combined tires are used, aggregated with analogs of low pressure. For wheels, cast-type galvanized metal discs are also suitable. Thanks to their corrosion protection, they will last much longer than conventional metal versions. Distribution and adjustment of the received load will allow the gearbox to operate in four ranges from the VAZ car. This will also allow you to adjust the speed and optimize fuel consumption.

All-terrain vehicles based on the "Ural"

It is really possible to make homemade products on a pneumatic drive from a Ural motorcycle. The main bearing part is a frame arc, consisting of pipe elements with a diameter of at least 4.2 mm. The rigidity of the structure is also provided by pipes, which form a reinforced triangle, and spacers of a similar material. Such a complicated configuration makes it possible to correctly distribute the mass of the all-terrain vehicle, taking into account the transportation of additional cargo or a passenger.

Made on a motorcycle-type pneumatic drive, they allow the use of regular seats. In this case, the mounting method remains the same. They are placed taking into account the build and height of the average person in terms of distance from each other. This provides a convenient boarding and travel experience. The factory seat handles are swapped for 24cm rigid crossbars.

This ensures the safety of the passenger, allowing him to hold securely when driving over difficult terrain. A drawer fastening is provided as an additional equipment. It serves as a reservoir for storing a first aid kit, tools and other useful items. An additional fuel tank with a capacity of 5-7 liters can be mounted on the rear of the frame.

How to make an air suspension with your own hands from a motorcycle?

The rear-wheel drive of the unit in question is very simple in design and easy to manufacture. The main thing is to take into account the location of the axle shafts and the load on them when assembling the part. In this regard, the yoke should be welded after assembly of the main unit. Analogs from GAZ-69 or 21 are suitable as axial elements.

If the installation of disc wheels is provided, it is better to use special studs, and connect the axle to the disc by means of a special flange. Do-it-yourself snowmobiles will also require a gimbal with suitable bearings with a diameter of 76 mm. Each axle shaft will rotate independently, which will ensure reliable and practical operation of the undercarriage of the unit.

Car enthusiasts have probably come across serial or home-made vehicles with huge wheels installed. These wheels are mainly produced according to special orders. Such designs are called low-pressure tires or abbreviated SND. Such tires are widely used on vehicles of the military, fishermen, travelers, hunters, agricultural and geological reconnaissance equipment.

The name itself immediately defines the main distinguishing feature of these tires - the wheels of this type have low pressure, so outwardly they resemble the pillows on which the car moves. SNDs exert little pressure on the surface, which results in an optimal effect for off-road driving. Despite the reduced pressure on the ground surface, the degree of traction is still high, which allows you to move confidently over rough terrain, swamps and mud.

Numerous studies have shown that low pressure tires are 20% more efficient than standard tires.

SND have several distinctive features:

• Due to the special design, these tires have an increased area of ​​contact with the surface, so that cars on such rubber can overcome almost any obstacle.
• A small specific pressure allows the use of such tires on agricultural machinery, since during soil cultivation it is necessary to ensure minimum loads on the soil. For the same reason, SND are used on a variety of.
• Driving a car equipped with such wheels requires special skills. It is recommended to drive on hard surfaces as little as possible, and to take turns smoothly, since the side surfaces of the SNP are their weakest point, very unstable.

Depending on the architecture of the structure and functional characteristics, several types are distinguished:

The cost of low pressure tires is several times higher than the cost of conventional tires. If we take into account the fact that it is necessary to manufacture them for specialized purposes, then the prices can reach half the cost of the vehicle. That is why, most often, extreme car enthusiasts make such rubber on their own.

Homemade wheels and tires

First of all, you need to choose the source material on the basis of which such tires will be made. It is best if tires from air transport become the basis of the design - they are made of high-strength rubber of the best quality. Tires from agricultural machinery or industrial all-terrain vehicles are also suitable.

Each bus consists of several interconnected elements. For the manufacture of SND, it is necessary to remove excess rubber from the tread and side surfaces, and from the inside, remove the landing cores. If necessary, even the rubberized part of the cord base can be removed, but it is quite difficult to do this without affecting the nearby layer. So, the main task is to lighten the tires and make them such that they will allow the car to move through difficult terrain and weak soils.

The manufacturing procedure includes several stages:

1. We clean, wash and dry the workpiece. We mark with a marker the patterns of a new one (places of cuts).
   
   
2. We cut through the rubber along the inner perimeter of the circle to rip out all the excess wire.
   
   
3. After that we cut out small "windows".
   
   
4. Through the holes we see a wire, which we pry with the help of improvised tools.
   
   
5. We fix the tire and hook the wire to the winch.
   
   
6. With the help of a winch, we pull out all the wire.
   
   
7. We cut the perimeter of the circle just below the cord and fix it with pliers.
   
   
8. We tear off excess rubber using a winch.
   
   
9. Cut the stretched piece of rubber with a knife.
   
   
10. From the surface of the tire (treads and sidewalls) we remove the main part of the material, layer by layer, until the tire is represented exclusively by the original carcass.
    
    
11. We clean the surfaces with sandpaper.
    
    
12. Putting the frame together. We weld metal tubes (plates) to the disk and weld them together using similar pipes of the appropriate size.
    
    
13. We carefully grind the resulting workpiece so that the wheel chamber is not damaged by sharp fragments left after welding.
    
    
14. We put the camera on the disk and pump up the tire. As a result, we get a ready-made wheel design that can be used for predetermined purposes.
    
    
15. It's time to "put" the resulting wheels on the transport and test on the go.

This video describes the tire peeling technology and the machine for this procedure.

Homemade products and Syrian cars on unusual wheels

Examples of factory vehicles and products made by craftsmen, in the design of which SND are used.

As you can see, swamp rovers, caracats and ATVs cannot do without SND, the special design of which makes it easy to move on a swampy or snow-covered surface. On ATVs and cross-country motorcycles, these tires are also quite often installed. Thanks to them, ATVs pass rough terrain faster and more efficiently.
