How to assemble a karakat with your own hands drawings. Do-it-yourself homemade caracat from a walk-behind tractor

A home-made light all-terrain vehicle, but at the same time very powerful and easy to manufacture, does not require large expenses, assembled from motorcycles - do-it-yourself karakat.

The last to make this all-terrain vehicle. Parts used, from different motorcycles. Reduced weight. The length has increased by 20 cm, due to this, the control has become easier. The wheels have already been made, the belts are shorter, the weight of the wheel has become less compared to the previous all-terrain vehicle. The engine load has been reduced. Significantly reduced fuel consumption

It is convenient to ride on this all-terrain vehicle alone, it is very light. But even two are lucky easily, and confidently overcoming any obstacles.

Another advantage is that you can use the engine from the Minsk motorcycle, without any alterations. The only thing to do is to add a mount on the karakat frame for the Minsk motorcycle muffler.

If you make a trailer on the same wheels, then even the engine from Minsk freely pulls a trailer with a load of 250 kg.

Details and material for building a karakat with your own hands

From a motorcycle, the first and main use is of course the engine. Further, a steering column with a steering wheel, switches, a clutch lever with a cable, a headlight, a fuel tank with a cap and a tap, a chain, a driven sprocket from the rear wheel, a seat with a mount, an air filter with an intake silencer and couplings, connecting wires, an ignition coil and a switch, high voltage spark plug wire.

The frame from motorcycles was not completely used, but only certain sections were cut out. The main material for the frame are pipes of different sizes. A 34 mm pipe with a total length turned out to be about 5 meters 30 cm. And 28 mm pipes were used, if all the trimmings were connected, it turned out to be about 8 meters. Several cuts used various smaller sizes.

For the rear axle, you need a pipe with a diameter of 50 mm, a wall thickness of 5 mm, a length of 1 meter 42 cm. In the assembly process, the wire was still useful - 6 mm, iron - 2 mm, bearings 210 - 3 pieces, bearings 204 - 4 pieces. Electric motor DC 12 volts from the stove of the car. Four diodes D-242.

This material is quite enough to assemble a light three-wheeled device on cameras. The speed will not be great and this is not the main thing. The main patency will be excellent on any off-road. Easily overcome long distances through swamps, rivers. Pneumatics on cameras can be used in conditions where other equipment will not pass.

Some magazines constantly acquaint their readers with various amphibious all-terrain vehicles, multi-wheeled vehicles, snowmobiles, snowmobiles, motor sledges. Such articles acquaint their readers not only with individual successful designs of cars, but also with the drawings of all-terrain vehicles, provide information about different areas of search, including amateur ones.

In magazines, over the past seven years, review articles have been published that analyze all the known schemes of various amphibious all-terrain vehicles and other hovercraft. And also forecasts were made for "tomorrow", what changes in the designs of motorized sleds and sledges are expected in the future. Various prospects for the development of equipment designed to work in difficult conditions in difficult places were considered. Not all fans of this technology have such an opportunity to follow all the news and the latest activities of their colleagues, all the achievements of special firms located abroad. Review articles on new designs of micro all-terrain vehicles in foreign companies are published with the light hand of printed publications. Articles of this kind are very helpful for amphibious all-terrain vehicle enthusiasts to broaden their horizons, choose the right design direction, overcome difficulties in implementing their own projects, thanks to the provided all-terrain vehicle drawings.

In one of the publications, an amphibious velomobile was considered, which described in detail how it works, as well as the snowmobiles that were created by the Saratov do-it-yourselfers Bykov and Yakovlev. Rationality and completeness of the design solution, which immediately attracts attention.

Ski-wheeled snowmobiles, created by Timokhin from Tula, immediately won the reader's sympathy. The machines were tested in the Arctic and immediately after the tests became widely known among lovers of this kind of technology. Drawings of all-terrain vehicles were also provided.

The most interesting news was presented to the reader about "all-average" and all-season all-terrain vehicles. Snowmobiles, snowmobiles, motor sledges and other vehicles of this type are usually used at certain times of the year, in one or two environments, either on land or on water. Whereas amphibious hovercraft are used at any time of the year and have no restrictions on use. This technique can overcome any obstacle in all four seasons. The only disadvantage of this technique is that it overcomes obstacles on level ground, but the wooded part of our planet is not subject to them. In the forest, you can't accelerate to the WUA.

For such places with rough terrain, articles were presented that talked about amphibious all-terrain vehicles with low-pressure tires. This technique has wide-profile tires with low pressure, they can be used all year round, regardless of the terrain, as these machines can swim.

An article about the pneumatic walker created by Gromov from Cherepovets, written after the program “You Can Do It” on Central Television, described this universal machine in detail and even provided drawings of the all-terrain vehicle. The pneumatic hoist is indeed universal, capable of overcoming any obstacles. Tests of the pneumatic duct were carried out in the vicinity of Cherepovets itself. A special correspondent who was present at the tests wrote that the testers did not dare to drive close to the swamp and unloaded parts of the pneumatic duct from the trunk right in the forest. It took only seven minutes to assemble the air duct, only nineteen nuts had to be tightened. The modest dimensions of the car, a meter in height and a little more than a meter in width, a length of a little more than two meters. Four wheels, a body, a frame with an engine, very reminiscent of the Kirovets tractor.

Immediately after assembly, Gromov got behind the wheel, started the engine, and we drove off. The "flexible" frame of the all-terrain vehicle easily allowed him to maneuver between the pines. Sufficient speed of the car, good maneuverability helped us, when we drove out of their forests, to easily overcome sandy soil, bumps that appeared after a mossy carpet. And here we are eating on a green meadow, in some places on our way we come across stunted pines. We added gas, and the wonderful all-terrain vehicle rolled easily through the short grass. And then the correspondent noticed that the wheels of the all-terrain vehicle were wet with water and realized that the all-terrain vehicle was driving through the swamp, leaving behind a barely noticeable trail. The correspondent asked Gromov to stop and tried to stand on the green cover, but he immediately fell into the muddy slush almost knee-deep, and the car stood nearby as if on a parking lot, climbing onto the nearest bump, the correspondent took a photo of Alexander Nikolayevich right in the middle of the swamp. When the testers drove back, the correspondent did not dare to leave the car in the swamp anymore ... Further, the tests took place on the banks of the Mologa River, which are heavily indented by external waters. The amphibian all-terrain vehicle easily overcame steep climbs, during which it was difficult to stay on the seat, and the car did not even think of slipping on any of the obstacles. The articulated connection of the halves of the frame allowed the wheels not to lose grip on the ground with any unevenness. The correspondent received the most exciting impressions when the tests were carried out on the water. Without slowing down, the car drove straight from the steep bank onto the water surface, the boys, who were not far away, roared with delight! The car went along the bottom and ... swam! True, not so fast, although the wheels continued to rotate at full speed, since at first Gromov was not going to use the all-terrain vehicle as a boat, and therefore rowing surfaces (water hooks) were not provided. The car kept safely on the water.

Tests have shown that an amphibious all-terrain vehicle on a frame with an articulated joint and low-pressure tires is really all-terrain! It not only moves easily over rough terrain, but also easily carries cargo and two passengers, which are far from light.

The ease with which the machine overcame the steepest slopes suggests that the traction characteristics of the engine itself and the features of the chassis of the machine make it possible to use it as a tractor. And the creator wants to adapt his machine for processing a vegetable garden in the country! So what do we have? The frame is hinged and the drive on all four wheels, which gives good cross-country ability. The wheels have a constant grip on the ground, which prevents overloading individual wheels. Good all-terrain vehicle maneuverability, which allows the car to turn almost on the spot. Simple machine design. The frame of the all-terrain vehicle consists of two parts, which are interconnected by a hinge that rotates vertically. The front of the car is a rigid welded assembly with a fuel tank, a driver's seat, and a control pedal. The hinge having a vertical axis of rotation is two forks connected among themselves by powerful fingers. So that the wheels do not have friction between themselves when moving, restrictions are provided on the hinge. An axle, a swap body and a brake are attached to the rear of the frame. The hinge on the rear part has a horizontal axis of rotation, a casing is attached to the rear fork, it is fixed and has an internal thread with a bronze bushing, which acts as a bearing for the rear of the frame. The casing itself in the sleeve is held by a pin, which serves as a limiter for the angle of the hinged frame.

VP-150M - engine - installed on the machine across the movement, so it takes up less space and the cooling fan works better with this arrangement of the engine. The central mounting bracket is located on the casing under the very cylinder of the engine. The rear bracket is on the transmission housing, and the bottom one is on the axle block on the right. The fuel tank is attached to the engine crankcase and has a capacity of 5.5 liters; fuel from the tank enters the carburetor mechanically. On the front axle there is a clutch pedal - on the left and an accelerator pedal - on the right. The transmission lever is manual, a ball is welded to the toothed rod, for the convenience of switching speeds. The engine is started by a kickstater. The exhaust pipe is under the seat. The transmission of the machine is symmetrical from the axis of the bearing frame. The cardan shaft creates torque by means of a chain drive. A cardan shaft is machined from a bar, having slots at the ends, and sealing collars in the neck.

Other universal joints with crosses are borrowed from the Ural motorcycle. A brake from the Vyatka scooter is provided on the rear shaft, the control cable is brought to the steering wheel. The differential of the bridges of the machine is traditional, it has two gears from Moskvich412, and the semi-axial gears are made independently. A bevel gear was also taken from the Ural motorcycle. The steering of the all-terrain vehicle has a removable steering wheel, a worm gear, a vertical column, the thrust is regulated by two rocking chairs. The design of the wheel is also simple, the main element of which is an aluminum hub, the wheels are also aluminum. Tarpaulin belts are attached to the disks themselves, which hold the tire, as well as two chambers 720x310mm, located one in the other, the tarpaulin tape serves as protection with tucks with grouser. The hub is closed on the outside with a cover that protects it from dirt. The body consists of a welded steel frame, the panels of which are textolite. Three channels give the floor the necessary rigidity. The body of the all-terrain vehicle weighs only 6.5kgs, but the dimensions of the machine make it easy to fit two people and a load. Amphibious all-terrain vehicle does not require much maintenance. The most important thing is to make sure that the fuel in the tank does not run out, that the air pressure in the tires is at the level and the gear oil in the axles is in order. That's all the easy care that this wonderful amphibious all-terrain vehicle requires. If you want to make such a car, the drawings of the all-terrain vehicle can be found on the Internet, printed on plain paper and, of course, contact the designer of this wonderful machine, and you can become the proud owner of an amphibious all-terrain vehicle and visit the most inaccessible places in our country.

The topic of homemade vehicles is especially popular today. Many "craftsmen" are trying to make a karakat from standard vehicles, special equipment. How can you make a budget karakat using a walk-behind tractor (even the simplest Neva will do). At first glance, there are doubts about the qualities of technology, because visually it is a bulky and at the same time uncomfortable machine. In fact, a do-it-yourself karakat from a walk-behind tractor shows simply excellent performance and can easily move in difficult climates and difficult terrain. And if we talk about moving through swamps, various estuaries, in the mud, then such an all-terrain vehicle will become simply an indispensable solution for every person.

Do-it-yourself homemade caracat from a walk-behind tractor

The classic homemade version, when a karakat is made from a walk-behind tractor, can move without problems at speeds below 70 kilometers per hour, which is an excellent indicator for a number of roads with poor coverage. And if they are absent, such a vehicle will be simply necessary.

Scheme of a tricycle fracture

The unit is able to withstand significant loads, which is facilitated by a fairly strong and reliable suspension, welded from prepared steel pipes. The design is connected by hinges, which guarantees ease of movement and performance of even the most unusual maneuvers. True, the control of this unit requires a certain skill, because the execution does not provide for the presence of a worm gear. Below is a typical drawing of a homemade karakat.

Stages of developing a karakat

Conditionally, the following stages can be distinguished, how to assemble a floating karakat:

Frame creation
Making a pendant
Creation and installation of wheels
Engine and systems installation

Frame for karakat

First of all, you need to choose a suitable frame for installing all the necessary equipment and assemblies on it. It is desirable if it is a walk-behind tractor belonging to the middle or even heavy class of equipment.

In fact, even the most “advanced” karakat is nothing more than a self-made all-terrain vehicle, which is customarily installed on a frame with four (4x4) or even three wheels (three-wheeled). The choice of the number of wheels depends solely on the design features of the proposed vehicle, a pre-designed scheme.

The wheels must be “shod” in high-quality low-pressure tires, the design is driven by an installed powerful internal combustion engine.

Suspension

The suspension of a motoblock karakat will require special attention and precision on the part of the developer. At this stage, in addition to the suspension itself, the master will also need to make the rear axle, which is worked out exclusively with his own hands.

Rear axle drawing example

The suspension is a special design made of two separate parts connected together by means of hinges. The spars in this case must be mated with each other, for which a steering sleeve is used. Ultimately, it is possible to form independent front and rear suspensions.

The main condition is to achieve exceptionally high independence of the suspension, because. it is this indicator that allows the all-terrain vehicle to be operated in the most unpredictable places, guaranteeing the safety of the structure.

Maneuverability and cross-country ability should be the primary factors that you should pay attention to when making a home-made karakat design from a walk-behind tractor.

Karakat wheels, in fact, are the most expensive product, which will take a lot of time. You can either buy ready-made discs or try to make them yourself. It is worth noting that almost all vehicles (karakats), made as homemade products, are equipped not directly with wheels, but with tires and low pressure chambers. Especially for these purposes, it is best to choose products installed on trucks such as the Urals, KamAZ and others.

Alternatively, you can use the wheels from the trailers of these machines - if possible, you can purchase tires and a camera from the K-700 model. The most important thing to pay attention to is that the wheels should be large enough, which will make it easy to move off-road in the future, easily covering considerable distances without the risk of rolling over.

Engine and systems

Installation of the engine and other systems is carried out at the last stages of work. These operations are carried out when a suspension with prepared wheels is installed on the vehicle frame.

In addition to the engine, clutch systems, brake elements, as well as systems responsible for removing burnt fuel products from mechanisms are mounted.

When the engine is installed, it is mandatory to conduct a full test of the karakat, then it can be operated.

It is worth noting that, depending on the walk-behind tractor used as the initial unit, the power of the vehicle can also be calculated.

For assembly, you will need to use a standard set of tools and process equipment and improvised materials. It is important to ensure the maximum possible safety of the driver of the vehicle and to exclude the possibility of accidents. A do-it-yourself karakat from a walk-behind tractor will allow you to move around in harsh weather conditions without problems and will last a long period of time without the need for regular repairs and expensive maintenance.

What is karakat

In simple words, a karakat is a light homemade all-terrain vehicle with the simplest technical base on tires, equipped with three or four wheels with large low-pressure tires. The main idea of such machines is the use of ready-made units. For example, a variety of power plants can be used as an engine: from motorcycles to truck engines. There are caracats built on the basis of walk-behind tractors. At first glance, it may seem that such a machine, due to external clumsiness, is unlikely to have good driving characteristics. In fact, the opposite is true: karakats are strong, stable and truly "all-terrain".

How to build a karakat

The construction of the machine begins with the choice of the base. The scope for creativity here is endless, but most modern designers prefer the frame of a small motorcycle (like Izha). Such caracats have greater maneuverability, which means they are more useful in the forest and on uneven terrain. The suspension is welded independently and consists of two independent systems, fixed by a reinforced swivel joint. The wheels are the most interesting part of the karakat. These are either special low-pressure tires (it will be difficult to find cheaper than 50 thousand per set), or cameras from trucks or tractors. Cameras from helicopters and airplanes are best suited, but they are, again, quite expensive. The cameras are put on standard disks (stamping is also suitable) and attached to the suspension on a metal hub, to which strong tapes are screwed, braiding the wheel across. Then the engine, clutch, brakes and exhaust are installed on the karakat. The car is ready - we're going to test it.

Scope of application

Low-pressure wheels provide the karakat with a cross-country ability comparable to expensive tracked and wheeled all-terrain vehicles. Such a machine will easily overcome mud, snow, swampy terrain. Due to the buoyancy of the karakat, water barriers can also be forced on it. Small engines consume little fuel, so the high autonomy of homemade pneumatic ducts allows you to travel long distances. Especially true for advanced fishermen and hunters. Karakat is designed exclusively for dirt roads and off-road, and it does not need high speed at all. On average, the maximum speed for homemade products of this type is 70 kilometers per hour.

Good Examples

The three-wheeled karakat "Samson" is built on the basis of motorcycles IZH Jupiter-5 and IZH 6.920GR (cargo motorcycle), so its owner is unlikely to have problems with spare parts. For all technical characteristics, Samson holds a high bar. Sufficient engine power allows you to tow a large trailer, and the original design of the rims makes it possible to put on low-pressure factory-produced tires BEL-79. Another good example is an unnamed karakat with an engine from a Ural motorcycle with a capacity of 36 horsepower. A distinctive feature of this instance was additional blades to overcome large water barriers. Sergey, the creator of the air duct from Kirov, estimated his creation at 160 thousand rubles.

In my opinion, the design of a four-wheeled light karakat is very interesting in terms of simplicity and budget. It can be seen that the author went to the creation of this device through the wilds of trial and error, since the design is non-standard already in its appearance. It is clear that there is no beauty and aesthetics, but this is usually the case if the device is not for show, but for work. This is what this really light floating caracat on four wheels looks like.

The T200 engine from a scooter, 10 l / s, is very economical in terms of consumption, about 4-5 liters per 100 km, or about a liter per hour. Between the rear wheels and the engine, a transmission from the ancient "Moskvich" is installed. Four gears and much-needed reverse gear. Only 4 gears in the engine and four in the box. The speed from the very minimum for overcoming swamps in first gears in both boxes is 2-4 km / h, and up to 50 km / h on good roads.

According to the author: This karakat was created as a simple and cheap unpretentious non-sinking all-terrain vehicle. Before him, there was experience with three-wheeled karakats and even tried a two-hundred-liter barrel with three Zilovsky chambers instead of a rear wheel, but it’s not that. This karakat turned out to be much easier and more passable than what was done earlier. Such a narrow design came about because the rear morst is an inseparable straight axle and does not have a differential. Without a differential, the cross-country ability increases significantly, but it is difficult to drive on a dry road and asphalt, so they made the car narrow and long.

In general, it took about 2.5 years to fine-tune this all-terrain vehicle, a lot of time and nerves were spent. At first, the design was "raw", then the wheel would break off, then the front beam would turn out, then at the most inopportune moment, somewhere in the swamp slurry, the chain would fly off due to crowded grass. In general, as they were used, weaknesses in the design were refined and strengthened. Now the design is very reliable and proven, so we drive long distances without fear.

A standard chain and an asterisk are installed on the engine, the chain transmits torque to the input shaft of the Moskvichevskaya box, the box is short, with a clutch cover cut off by a grinder. A box from some old Moskvich is older than the 412th.

Since the box is not designed for lateral loads, I made a rack with an additional thrust bearing. Well, they probably noticed the tractor magneto, this is a simple and reliable ignition, this can be seen in many.

The wheel is made on the basis of a motorcycle rim with welded wide rims.

Steering wheel from the Zaparozhets

Karakat brakes are made on a belt, it's simple, a disk under the belt and a pedal that pulls it. It brakes well and reliably, nowhere is easier and you can quickly repair it.

Almost everything has been said about the construction, now you can show a photo of what it was actually built for in the first place. This is a crucian carp, a very tasty crucian carp located in a hard-to-reach lake, where there is a lot of it, since only desperate all-terrain vehicles get there, well, I myself. We also drive through the swamps for lingonberries and many other places, in general, for fishing and trips along our roads, an indispensable and economical thing.

I am repairing a broken wheel, of course, this does not happen often, but it does happen, very sharp roots of branches broken by the wheel come across. The holes in the tire are made specifically to lighten the wheel, and due to them a certain tread is formed. So the wheel rows on the water and lighter, keeps its shape. Wheel "encouragement". I peeled off with a drill with a mounted crown made of a pipe somewhere 50-60mm and sharpened sharply. I cut off the rubber from the sides with a sharpened ax. The holes were cut with the same crown.

Here are some more photos where a karakat is captured.

A little malnourished home and flattened the front wheel. But slowly drove on a bare drive.

Here is another one from a trip for lingonberries, though this year there are almost none. Here are some more mushrooms.

Another photo from a recent trip to a distant lake. During the trip, it turned out that the chain from the engine to the box was already very worn out and stretched, it's time to change it. And upon arrival home, I discovered that the locking ring on the rear wheel rim popped out and one edge of the tire was disassembled. Most likely the result of jumping over bumps and trees. And crucian carp was caught perfectly, crucian carp is very tasty here, not so on other lakes, but getting here is 30 km away and a swamp.

This photo is halfway to the lake, we were driving together, a partner on a motorcycle Minsk, as the swamp began, he moved to the room leaving the motorcycle. I want to say a few more words about patency.

If we compare, say, with all-wheel drive and heavy vehicles, then this karakat is in no way inferior and even superior, although it has only rear-wheel drive. Somehow, on a trip to the lake, I discovered that someone was trying to get to the lake along my trodden road, but before reaching 50 meters he got stuck in a swamp, and it is clear that his release was difficult, as the poles were thrown into everything around. As a result, the all-terrain vehicle was turned around and went to the lake on foot. And I drive there without any problems at all.

Karakat has two trunks. In general, you can ride it with three of us, but usually we ride with a partner or I am alone. If the road is dry, then I pump up the chambers harder and if there is luggage, then I overload it on the front, thereby unloading the rear wheels, and it’s easy to drive without a differential. And if you have to overcome continuous liquid off-road, then on the contrary, I lower the wheels and load everything into the rear trunk, loading the rear wheels.
