Unfortunately, not every person has the opportunity to purchase a quad bike in the store. All over or less interesting models are now quite expensive, and buy a quad bike support is always a certain risk. In this regard, many motorists advise to make a four-wheeled all-terrain vehicle personally, I use the engine and spare parts from some old Soviet motorcycle. Previously, we already told you about how to make a quad bike from the Ural motorcycle. In today's article, we will talk about other donors that you can use if you decide to collect quad bike with your own hands.
Why should you collect quad bike with your own hands?
Collect a four-wheeled all-terrain vehicle personally, it definitely helps to solve several problems. The first reason, because of which people decide to make a homemade quad bike, this is of course a small budget. If you analyze market prices for quad bikes, it can be understood that such vehicles can be considered almost for luxury. Prices for the simplest and low-power models begin from 150 thousand rubles, for example, Yamaha Blaster YFS200. Such a single "quadric" is in principle enough, but the capacity will be lacking forever.
But the models of quad bikes with engines, 500-800 cm 3 will cost much more expensive, about 500 thousand rubles. Chinese models, such as russian manufacturer Stels, but they will have to follow well. New all-terrain vehicles of this brand will cost approximately 300-400 thousand rubles, but the engines are already much more interesting - 45-70 hp
Nuances in the operation of homemade quadric
If you definitely decided to make a quad bike with your own hands, then you should know about the intricacies of its operation. In principle, if all-terrain vessels are needed for riding on impassive places, where patrol cars never happened, then worrying, probably nothing. You will have to face problems if you are planning to ride even on small settlements, which sometimes come patrol cars. Catching you without documents for this vehicle, then with a probability of 99% you will take it. All the difficulty is to register a self-made quad bike, because in the traffic police, you will most likely refuse. In a good way, you can register the homemade, but it is extremely difficult to do it. Therefore, the assembly of the self-made quad bike makes sense only if you exploit it in some wilderness.
Determine the choice
So how to make quad bike with your own hands? When creating a homemade quad bike, we need to decide on the donor, that is, a motorcycle that will underlie our project. For the four-wheeled all-wheel drive, old soviet motorcycles. With them, we can borrow the engine with a gearbox, frame, steering wheel and if you wish, details such as a tank, seating and other elements. Since we have already had an article about homemade quad bike from the Ural motorcycle, then in this review we will talk about how to make a quad bike based on the IL motorcycle.
For our goal, we will suit almost all models of motorcycles from the Izhevsk plant. The only thing that is important to understand is the engine power. Still, the final result will be quite heavy design, so the best solution will be the use of the latest models - Izh Jupiter 5 or IL Planet 5. More interesting models, like Izh Planet Sport consider no sense, because it's not easy to find them, but if possible , it is better to restore them, because the motorcycle is quite rare and interesting. Go to the main thing, how to make a quad bike and what is needed for this.
Rear suspension
Once you have decided on the donor, in our case it is Izh Jupiter 5, you must fully disassemble the motorcycle. After disassembly, we will need a frame on which everything was holding, including the engine. It is quite logical that to increase the reliability of the design, the frame must be strengthened in several places.
Now you need to cook the rear axle so that instead of the wheel on the axis, the bearing block with the chain drive can be up. An example, you can see in the photo. As a suspension, you can use conventional shock absorbers from the motorcycle, and for the rear axle it will be details from the old car Zhiguli. You can go more complicated and install a monoamorter, but then again you will have to look for spare parts from the car, for example, with the same Zhiguli or Oka.
Front suspension
As soon as the rear suspension is completed and installed, you can move to the front of the motorcycle, in which everything is somewhat more complicated. In the case when we dealt with the rear suspension, we had the opportunity to choose how many shock absorber would be installed. When creating the front suspension, we have only one option - use two shock absorber.
The Oka car is perfectly suitable for the front part of the Quadrocycle. With it we will need shock absorbers, rotary knots and steering trapezium. However, be prepared for the fact that spare parts will still have to change, - something to weld, cut off, to refine. Also not bad and more simple optionwill install a monoblock with fixed wheel planes. Then you do not have to look for a steering trapeze, couplings, hinges and other parts.
The monoblock is a truly simple option, because it will take the installation literally time. The only minus of such a front suspension design is a heavier mechanism. Turn the steering wheel will be somewhat more complicated than when suspension with shock absorbers.
Engine
Many wondering how to make quad bike with their own hands, they understand what to start with the engine. And indeed, the main detail in the future ATV is the engine. From how powerful it will depend on the final result, and in general the whole design. Of course, you can leave the engine from the donor motorcycle, but as a result, "quadric" will not be so powerful. If you have a little more serious about creating all-terrain vehicles, then setting more powerful engine It will be an excellent solution. We hope that we answered your question about how to make a quad bike.
It was going to purely for entertainment purposes, so the author was focused on industrial quad bikes and collecting their car. However, there are a number of constructive differences that have positively influenced the passability of all-terrain vehicles and significantly allocate it against the background of quad bikes of the standard configuration.
The machine has excellent quality of patency and reliability, largely due to a small weight.
During the construction of this model of self-made quad bike, the following parts and materials were used:
1) Water pipe diameter 32 mm
2) Pipe 27 mm
3) Engine internal combustion from car an eye 11113
4) gearbox from the same Oka
5) front and rear gearboxes from classic vase
6) hubs and grenades from VAZ 2109
7) Fiberglass
Consider in more detail the stages of the construction of this all-pass:
Suspension all-terrain vehicle homemade design, It is organized with a-shaped levers, which are made of a pipe with a diameter of 27 mm.
The engine and gearbox from the OKE car was installed, the differential was welded.
Gear ratio The ratio of the front and rear gearboxes Equally 43 to 11, they were redone under the inner grenades from the Lada nine.
Hubs and disc brakes from the VAZ 2109 were installed, and the wheels were supplied 15 radius through spacers.
Initially, it was planned to make a clutch on the steering wheel like a motorcycle, but then it was still decided to make it under the left foot, despite the unusual solution for the quad bike, it turned out to be quite convenient by the author. That is, there are no problems with switching gear on the go. Moreover, the all-terrain vehicle is able to touch on any gear, even with a passenger on board, the engine power is enough. Therefore, transmissions are not switched as often, when traveling along the roadway, only the third and fourth transmission are mainly used, and the first and second of the road, respectively, are used.
A dispensing box of own design of the author was organized, which it became possible to shut down front Bridge. The following is a photo of the entire mechanism for turning off the front axle, where you can see the main elements of the details:
Works were performed on the rear suspension of the all-terrain vehicle:
Frame preparation Machines for fiberglass pasting machine:
The process of fixing fiberglass by car:
Then the author began paining work on all-terrain vehicles:
A vulnerable design site, as you might notice from photos, are anthers on grenades. The author has not yet decided how to protect them from possible breaks.
In the following photo, the gear selection mechanism is excellent, as seen in the photo, the lever was slightly distinguished from the engine, since before that it was installed closer and the author often burned about the silencer, the likelihood of such an injury was taken on rear stroke. At the moment, the problem is completely eliminated by transferring the lever:
There is no photo on the radiator yet, and what exactly interests?
The radiator of all-terrain truck is hidden under the plastic right in front of the instrument shield, despite the fact that the hole that is existing is very small, it is enough to cool the machine. Although problems may occur when driving through strong dirt, since the hole is easily clogged, and the cooling from the incoming air does not work. But the fan copes with a similar load, although the all-terrain vehicle is not operated by strong dirt. In addition, the fan turns on only with truly heavy loads, which is extremely rare.
The reason for this is the fact that the device itself turned out to be quite lightweight and the engine from the Oka perfectly copes with the loads.
Below is a photo of the placement of the radiator:
Werethod has an approximate weight of about 450 kilograms.
Video tests all-terrain vehicle when driving through the snow:
If you have looked at the video, you probably paid attention to the sinking of the rear wheel already a few meters, which should say about the work of the rear differential. This all-terrain vehicle is very different from industrial, as they have rear Differential No I. rear axle Always rowing, which does not slowly interfere with the controllability of a quad bike, since the width of the car is small.
The author also wanted to initially brew the rear differential, but thought it would always be done, and decided to try to ride while differential. But since the passability of the all-terrain costs arranged and problems with the rear axle was not observed, then there was no desire to disassemble the design and brew the rear differential from the author.
That is why the all-terrain vehicle remained with the rear differential.
The only author plans to install more serious wheels on the all-terrain vehicle. Either remove the supports for disks 15, by installing disks with a breakdown of 4 per 100 from the Logan or Opel, which are superbly suitable for the VAZ hubs.
Quad bikes can be equipped with two types of engines: electric and gasoline. Electrical motors have less power and low energy. If you take an average quad circuit with an electric motor, the stroke reserve will be approximately an hour of time, and then a long battery charging is required. In this regard, such type of motor is equipped with children's models of quadrocycles.
The most common engines for quad bikes
Gasoline engines got the wider distribution in quad bike construction. They give out high powerwhich in a pair with transmissions is converted into a high torque. Thanks to this, quad bikes feel so beautifully on any off-road. Also, an important indicator is the specific capacity (power assigned to a unit of mass). The low weight of the motorcycle device in a pair with a good engine allows you to show four-wheeled amazing permeability. For quad bickers, motors are used with a working volume of about 49 - 900 cubes. Of course, there is a smaller volume that are intended for children's versions of devices.
The difference between gasoline engines for quad biccles
Gasoline engines for quad bikes can be divided into two large groups: two-stroke and four-stroke. The difference between these two types is that in the two-stroke engine one working cycle piston makes per move. In the four-stroke engine injection, compression, detonation and release is made in two stroke of the piston. Based on this, it can be said that the two-stroke engine produces greater power with the same amount of cylinders. For example, the four-stroke engine is equipped with one most common ATV 300 quad bikes. Many believe that in fuel two-stroke engine It is necessary to pour oil. However, this is not quite the right judgment, since there are many engines that do not require this, for example, Catarpillar motors do not require oil in gasoline. Of course, the conversations that the motors of the two-stroke design produce more harmful substances - This is true, but it should be understood that this is due to the greater frequency of fuel combustion in the cylinder. It can be noted that engineering technologies today are developed so much that motors emissions different types A little different and minimized.
Engine maintenance for quad bikes
The performance of the power unit depends directly on the quality of service and frequency. Service maintenance two-stroke engines It is produced much more often compared to four-stroke. This is primarily due to the fact that in the cylinder there is more frequent combustion of the fuel-air mixture. As a result, it is achieved higher working temperature Engine. Such factors lead to a more rapid wear of the power unit operating on the two-stroke cycle.
Therefore, when buying a quad bike with a two-stroke engine, be prepared for more frequent maintenance and purchase of spare parts. The indisputable advantage of the two-stroke engine is its low weight, simplicity. But there are a lot of flaws: high flow Oil and fuel, high vibration and noise. The two-stroke engine is equipped, for example, an ATV-024-15 quad bike.
However, athletes and lovers to drive on quad bikes little attention to collect the engine, the most, perhaps, the main point in the choice becomes the output. By power, it can be noted, the superiority of the two-stroke engine in front of the four-stroke with the same amount.
Introducing the Quadrocycle of our permanent author S. Plentneva from the city of Points of Perm Region. The next car constructed indicates the increased design level and the professional skills of its creator. However, judge for yourself ...
Cow a year since then when having left the garage, tested his first quad bike with the rear leading wheels on the basis of a heavy motorcycle "Ural-2". And now I came to: and not now all-wheel drive ATV (from English. All Terrain. Vehicle. - all-terrain vehicle; Such an international designation received similar cars).
Labor year is 3-4 hours after work and on weekends - and new car It was ready for testing, there were only small (and I would say pleasant) refinement: connecting light equipment, installing the ignition lock, rear view mirrors and other little things.
Force aggregate For my Quadrocycle, the motor was from the car "Oka" - 32-strong, two-cylinder, four-stroke, liquid cooling. And if for the car its power often turned out to be not enough, then for quad bikes should have been enough with interest.
The main data of the Quadrocycle:
Mass, kg ............................................... .......... 430.
Length, mm ........................................................... ........ 2300.
Width, mm (on the outer sidewalls of tires) ......... 1250
Height, mm:
on the roll ................................................ .......... 1250.
On the saddle ................................................ .......... 900.
Ground clearance, mm ...................................... 300
Base, mm ............................................... .......... 1430.
Pitch, mm ................................................. ........ 1045.
Maximum speed, km / h .............................. 65
Rama cars - Spatial, welded. Its main elements (two pairs of spars: the upper and lower) are made of round tubes of type VGP-25 (water-based diameter of 25 mm with a wall thickness of 3.2 mm), auxiliary (so-in, crossbar, etc.) - from WGT-20. Spars - bent: the lower in the horizontal plane, the top - in the vertical. Flex a pipe on the pipe bender, "on the cold". The eyeles (pairs of ears) for fastening the levers and shock absorbers of the suspension welded to the frame immediately, and various brackets - as nodes and aggregates (by "place").
Transmission of all pass - peculiar. Although the machine is all-wheel drive, but dispensing box There is no. As you know, the engine is located in the "Oka", and on the Quad bike it is set along. This allowed to direct the output shafts from the transmission change box (CAT) not on the right and left wheel (both in the car), but on the front and rear axle. That's just myself force aggregate, Breakfied with a "basket" of clutch and gearbox, had to be moved relative to the longitudinal plane of symmetry a little left to reduce the horizontal angle of longitudinal swivels of transmissions. Well, their vertical angles were insignificant.
Sound transmission from units of various domestic cars, mostly "VAZ" models. But the finished industrial aggregates also had to refine. For example, from the PPC (from "Oka") to ensure optimal (reduced) speed and increase the torque deleted the main gear pair and replaced it on chain transmission. The shifting stock also made another - extended, with releases on both sides of the checkpoint. The rod can be recorded in three positions: to include the 1st and 2nd gear, 3rd and 4th and rear. The selection lever of these provisions is on the right side, and the speed switch lever is with the left.
Intercole reducers - OT rear axles VAZ "Classics", only their semi-axes together with "stockings" are removed and replaced with shafts with shurthers from front-wheel drive models. Shruses as hinges are used in the remaining intermediate trash shafts.
There are no reduced gears and blocking differentials.
Steering - Motorcycle type (lever and shaft) at the top and automotive type (with steering rods) - downstairs, just simplified, without a steering mechanism, with one compartment. The steering wheel first used from the Minsk motorcycle, with a pipe diameter of 22 mm, but it turned out to be a bit thin. Later found and set from the "Ural" motorcycle. The steering shaft is from the pipe with a diameter of 20 mm and a thickness of the wall of 2.8 mm. At the bottom end, it has a stroke limiter. At the bottom of the shaft rests on the stubborn bearing, and in the middle part turns into the junction of the piping bracket-sleeve.
Cup Made of steel sheet with a thickness of 8 mm in the form resembling the letter "T". The edge of the "racks" performed a hole with a diameter of 20 mm - the steering shaft is inserted into it, and in the ears - the tapered holes under the ball tips of the steering. These holes are enhanced by suitable welded washers. The bark ears are slightly bent down so that they are almost parallel to the traction.
Wheels - 15-inch, from the car "Chevrolet-Niva". Tires with an appropriate planting diameter of 205/70 (width / height as a percentage of width) with off-road tread pattern. The diameter of the wheel running is about 660 mm.
Suspension wheels - independent, on two triangular transverse levers each (upper and lower) with shock absorbers from the "Oka" car (front). The levers are welded from round tubes of type VGP-20. Elastic elements (springs) and shock absorbers - from the "Oka" car (rear). In the wheels of the front levers, the hubs are welded and swivel fists - From the car VAZ-2109. And those and others had to modify. In the hubs installed studs under the wheels from "Niva", and in the front fists - home-made swivel levers.
Muffler - homemade, two-piece. To protect against temperature storage boxes, covered with a remote cover, and insulated asbestos inlet.
KVAD biccles - Fiberglass. He shouted it for the first time, and therefore first examined the recommendations for the implementation of the relevant work. But as it turned out, this process is painstaking, although the result is worth it.
First made from steel square pipe section 10x10x1 mm Required body contours. Fortunately, this pipe is easily neat even with his hands through the knee. The contour welded to the frame with the help of jumpers from the same pipe, in places where then (after dusting of the kit), it would be possible to cut the "tape". Then, bent from an organity (wood-fiber plate) "Wings" and fixed them with self-draws to the contour and jumpers. Where the bend was obtained steep, fastened individual strips from the same organity. The front ended with a neopolistir acquired in a shopping store. It was possible to use foam or the same mounting foam, but the polystyrene foam turned out to be a more appropriate material - it is well cut in a sharp thin knife. Separate elements of it glued into the overall design on the mounting foam.
Falshbak - Complex form. It did not seem to be taken out of the organity. Therefore, by climbing the engine with a plastic film, it began to fill the places of the mounting foam intended for it. After each layer is a mandatory drying, otherwise the thick volume of the foam may not dry inside. Filled until the layers went beyond the contour. Finally, after complete drying, the foam became a knife to withdraw the desired shape. The verge burned down coarse sandpaper.
Under dashboard went into the course of dashboard "Oka". I fastened it on the blank, too, using a mounting foam.
Since foam is a large, pores filled with plaster and then processed. When the shape of the blanks began to answer the intended design and its surface became more or less smooth, covered the workpiece of PF-115 paint. Since I was not going to make the matrix on the nerve for dusting of the kit, and immediately soldered the bodywork on it, followed by the end of the surface to the perfect state, then the shpocking of the plaster and the painting of the nerve could be neglected.
So, the Bolon is ready and to solder the quality product, it took: 10 kg of epoxy resin, 1 kg of plasticizer to it and 1 kg of hardener, 15 robust meters of non-footwork fiberglass, 5 m of glassmate, brushes, gloves. It is very desirable to work in the means that protect the breath. And what they are more expensive, the more reliable. But the experience, as is known, can not buy, so it was gained in the process of work.
A transparent scotch used as a separation layer between the nerd and the product. Thoroughly, without skipping, glued to his stripes. There was only 1.5 rolls of wide scotch.
Divided the resin for 200-300 grams with a hardener and plasticizer. Applied measuring cups and syringes, which is not very convenient. Before that, cut the strips of fiberglass with such dimensions so that large cloths lay on the smooth surfaces, and on the irregularities, the sections of the fabric were able to repeat them without making folds. By the way, fiberglass to the measure stretches on the diagonal of the weave, "flowing" the desired form.
At first, one piece of nerve was smelled to thick epoxy resin, put the fiberglass on it and the resin was again impregnated from above. The neighboring piece of the tissue was glued by the same technology with a turn of 3-5 cm. A spore-resin had to work pretty quickly, and the higher its temperature, the faster. Yes, another resin has a slightly heated near the powerful lighting lamp for better flow.
After jumping a fiberglass in one layer, began to shock it with glassate. The glass made me quite thick, and they turned out to be good to dial the thickness of the product. But it does not fit irregularities, so I used it only on even (or with unrocked deflection) surfaces and without a twist. The impregnation of the resin was carried out in the same way as when working with fiberglass. It should only be noted that the resin for the impregnation of stiposate goes a lot, so it is necessary to breed it more. The uneven surfaces after the stickers of the stroke gambled into a few layers of the cloth. Each subsequent layer imposed after the previously gripped the previous one, so as not to break down the resin. And since the process of body cutting took no one day, after a day of the break "rough" the surface of large sandpaper and degrease - because the resin is completely cured during this time. The final layers over the mat again covered the glass kits, and not even one layer.
Since I needed the surface, as they say, than it is even better, the better, and the experience was not enough, then the failures and pits still remained - poured them wherever one resin, and where and with the imposition of fiberglass pieces. The resins did not have enough. I did not buy in Khozmaga, in boxes. I liked working with her more, because it was already packaged, and it remained only to mix the components. And she dried quickly than acquired on the company.
After a complete drying of the soldered body kit made a propyl in it, separating the product to three parts: rear wings and a back, a rashhead with a podswing, front wings and front. Caution, slightly going down and pulling out with arms with hint, separated the product in parts without much effort from the nerd.
Now, removing the part, began to process them separately, bringing to the desired result. In general, ordinary preparatory and painting work on "all" technology: first coarse grinding with the removal of large resin and fiberglass convexities; Then the painstaking embezzlement with a putty with fiberglass recesses; Next, grinding the outer surface and primer with a plasticizer. In conclusion - painting "metallic" and a coating with a varnish with a plasticizer.
The boyfriend also cut off and put it in a distant corner - just in case. Bidding attached to specially made and welded "on the place" fasteners on the frame.
Trunk. At the end, it was welded from thin-walled steel pipes with an outer diameter of 20 mm front and rear trunk, and in addition to them - and "kenguryatniki" replacing bumpers.

"Encyclopedia of Technologies and Methods" Plukh V.V. 1993-2007
Quad bike - actually any four-wheel transport, because in the Latin Quadro - "Four", on the SIS expanses under this title most often implies a all-wheel drive representing a motorcycle and car symbiosis. From the motorcycle, the quad bike adopted mobility, maneuverability, ease, speed, and from the car - the excellent characteristics of passability, power and controllability. As a result, it turned out a unique vehicle intended for various purposes.
The domestic market provides only foreign models of quadrocycles, the cost of which is often translated. At the same time with secondary market Vehicles can easily find used motorcycles and cars at an extremely low price.
For example, a motorcycle "Ural" - big, bulky, heavy and "voracious" has a beautiful four-stroke engine with rear transmission And worth the "penny". For this reason, enthusiasts are much cheaper and more interesting to create their own structures of these SUVs.
A typical factory representative of quad bikes is a brilliant, neatly assembled, strong and powerful.
His homemade fellow, which is a little inferior to externally, and in terms of power - and suppressed.
How to make quad bike do it yourself
Before starting the assembly, you need to make a detailed list of units and parts that will be needed to create your own brainchild, develop a work plan and drawing.
Engine: optimal choice
It is logical that first of all it is necessary to find the "heart" of the future "beast" - the power unit. It will suit absolutely any, starting from the usual motoblock and ending with six-liter V12 - there are such precedents. In most cases, motorcycle engines are used - they are economical and small-sized.

To use high gear ratios In terms of normal operation, the engine "Minsk" or "Urals" will be enough. In the summer there is a question of overheating, so you should choose the models with air cooled. Another good option is opposite engines Soviet production, an indisputable plus of which is a powerful traction and a completely unpretentious cardan transmission.
Suspension: Rear and Front
There are two most common rear suspension solutions for a quad bike.
- Reducer-cardan system. The design is obtained as easier and simple as possible, but there is no differential than, in principle, you can sacrifice the sake of previously mentioned advantages.
- Using car Bridge. The design is extremely severe, and if there is no desire to have a quad bike with a car base, you need to shorten the bridge, which is a very nontrivial occupation. Of the advantages it is worth allocating only the presence of differential, which is useful when moving along the tracks.
Huge opportunities are revealed to create anterior suspension and steering. Quadzerickel suspension levers carry a much smaller load than automotive, respectively, they can be made independently, using remedies for this. Optimal option - creation of suspension on the basis of the existing motorcycle "Ural".
Rama: drawings and alternative
The best solution is a robust design of pipes or profiles cooked with each other.
Ideal - to remove the frame from the donor motorcycle and draw the necessary elements - it eliminates problems, however, the design may be unnecessary.
Assembly of quad bike
Prepared required tools, donor vehicles and freeing time, you can start creating your own quad bike:
Thanks to a reliable design, a time-tested, excellent power and thrust, it is the "Ural" motorcycle is the most popular donor for homemade quad bikes.

As you can make sure, using outdated and inexpensive achievements of the Soviet Auto industry, you can create stunning devices that will sweep your pride and satisfy most of the transport tasks.
