Homemade tricycle with a VAZ engine. How to make a tricycle from a Ural

Not every person can find a vehicle to suit their own taste - especially if he wants something unusual. Therefore, it is worth thinking about the fact that you will have to do everything yourself - this is the only way out, but it is also the best if you understand mechanics and know a lot about assembly. But what can you put together on your own that will surprise everyone around you? A great example of this would be a tricycle - you can't buy them in stores, they are rarely mass produced, so you can create your own unique vehicle that will be the envy of everyone around you. However, a serious question arises here - how to make a tricycle with your own hands? To do this, you will need a wide variety of spare parts that you can get, while using the base and parts of one of the available motorcycles, such as the Ural or Izh. Chances are you have one of these in your garage. They can be easily converted into a tricycle or used to assemble your own unique model from scratch. Accordingly, you will need to think through everything in advance, make a drawing or download it from the Internet, because there are definitely enough enthusiasts like you on the network. And then you need to prepare for long and not the easiest work, which a few tips can make easier. You can read them further.

Tricycle layout

The first thing you need to think about if you are going to make a trike yourself is its layout. The fact is that power unit, which is usually located directly on the axle of motorcycles, thereby improving balance and reliability vehicle on the road, can no longer be there. Accordingly, you need to move it behind the axis, between two rear wheels. Naturally, this affects the stability and controllability of the tricycle - and not in the best way. But if you are an experienced driver, you will be able to adapt quite quickly. Moreover, this opens up some interesting prospects - for example, the ability to rear up your vehicle without any problems when developing at high speed. It looks extremely impressive and, unlike motorcycles, in this case you do not risk anything - this is an absolutely safe action (of course, if you do not pull the car too much, but on a motorcycle such a trick is much more difficult in any case). Accordingly, you will be able to impress everyone around you not only appearance your vehicle, but also its spectacular capabilities. This alone is enough to convince yourself to make a tricycle with your own hands.

Power unit

Naturally, when you think about making a tricycle with your own hands, you will need to choose suitable engine. In this case, you do not have to take a power unit from another motorcycle - an engine from a car will also work. The main thing is that it fits properly between the rear wheels. This way you can improve the performance of your vehicle. In some cases, you won’t even have to make any changes or improvements; in others, you won’t even have to replace the radiator or some other part. It is also recommended to install other mufflers, and increase their number by installing one on each cylinder. Naturally, there are other options - it all depends on which power unit you decide to choose. For example, if you make a tricycle from the Ural with your own hands, then it is better to replace the engine completely.

Gear box

When you make a tricycle from the Ural with your own hands, you definitely need to take into account where exactly the gearbox will be located. You already understand that the engine itself will be off the axle, behind the seat, between the two rear wheels. At the same time, make sure that it is attached as securely as possible in at least three places - especially if you plan to perform various tricks, as described above. As for the gearbox, it is better to install it on the left side of the steering wheel, since your right hand will be occupied most of the time. It is unlikely that if you take the engine and gearbox from a car, you will be able to make a design that is convenient enough to change gears without stopping driving. Also don't forget that you need to take care of connecting the box to the motor, which is a bit more difficult considering that it is now located a little further from the box than it should have been in the original. But if you're trying to figure out how to make a tricycle with your own hands, you always need to be prepared for these kinds of surprises and difficulties.

Suspension

It doesn’t matter whether you make a tricycle with your own hands from an Izh or any other motorcycle. You will have to remodel the suspension anyway front wheel. After all, the distribution of forces in a tricycle is very different from that observed in a regular motorcycle. To do this, you will need two pairs of consoles, as well as two powerful springs - if possible, try to get helicopter or airplane springs, but also springs from passenger cars can also be used if necessary. The consoles need to be connected to each other by levers, through which the axle of your front wheel will pass. Naturally, this is not the only way - there are a large number of ways to make a tricycle with your own hands. Drawings are available on the Internet (one of them is in our article), but this method is one of the most effective.

How the suspension works

If you are not making a trike out of a scooter with your own hands and are counting on a powerful and impressive model rather than a children's tricycle with a motor, then you need to seriously think about the action of your front wheel suspension. What are helicopter or airplane reasons for? The fact is that the movement of the wheel along the vertical axis will occur with much greater force than on a motorcycle, so you need to install stiff and durable springs - at least in the lower part of the suspension, which compensates for movement along the vertical axis. To compensate for movement along the horizontal axis, you can use softer springs - for example, from the Izh motorcycle. As you can see, assembling a tricycle with your own hands is quite difficult, but if you follow all the instructions, you will have a clear drawing and that’s it necessary materials, then we must cope.

Battery

The battery for your tricycle must be installed under the driver's seat - for this purpose a special frame is created, located above the engine. This way, everything important about your vehicle is in one place. You should also consider making the passenger seat behind the driver's seat. Not only does it allow more people to ride at the same time, it can be attached with saddlebags that will completely enclose the engine and battery, making your trike complete.

Installation of additional accessories

Before completing the work, you need to think about installing all the necessary elements, such as rear view mirrors and so on. All this needs to be thought out so that these devices can be easily and conveniently used in any situation.

Painting

Well, the final stage, of course, is painting, because you worked with individual parts from different vehicles. Most likely, they either do not have paint as such, or are painted in different colors. Accordingly, you need to ensure that your tricycle ends up looking perfect. After painting, you will need to cover all painted areas with clear varnish, and then polish, and if desired, chrome plate the metal parts to make the tricycle look like new.

Tricycle in its own way driving performance closer to an ATV and very useful in places where a regular Ural motorcycle cannot pass. In addition, it is more comfortable to travel long distances on a tricycle, which is important in rural areas. After the modification, the motorcycle becomes more stable, moves faster and can carry more cargo.

Do-it-yourself tricycle assembly from the Urals

Before starting work, it is necessary to think through the design of the future tricycle and the location of all elements. Ideally, make a drawing of the future vehicle.

Important design points:

All joints must be reinforced.
Car cups are welded to the top beam. It also serves as a support for shock absorbers.
Frames are welded to the central beam, which serve as footrests for passengers and also support the suspension bump stops.
The base for the pedal weights is the lower transverse tube, which is attached to the frame.
A support for the gearbox is also made on the transverse frame.

The main difference between a tricycle and a motorcycle is that the engine is located at the rear and therefore the center of gravity of the vehicle is shifted back. When accelerating, such a tricycle rears up a little. Below you can see a diagram of how to convert a Ural motorcycle into a tricycle.

1, 2 — front wheel and wing; 3 — front wheel suspension system; 4, 5 — headlight and headlight bracket; 6 — speedometer; 7 — gas tank; 8, 9 — gear lever and gearbox; 10 - battery; 11 — seat back; 12 — rear lights; 13 - air filter; 14 - engine; 15 — cooler; 16 — oil-air radiator; 17 — mufflers; 18 — rear wheel; 19 — elastic coupling; 20 — brake rod; 21 — brake pedal; 22 — beep; 23 — rear wing struts; 24 — shock absorbers; 25 — frame for mounting the radiator and muffler; 26, 27 — rear wing and its mounting bracket; 28 — front console; 29 — wing bracket; 30 — rear wheel suspension arms; 31, 32 — gas and brake handles, respectively; 33 — ignition switch; 34, 35 — clutch pedal and clutch rod; 36 — speed switch; 37 - steering wheel.

Location of tricycle parts

As we have already said, the engine of a Ural tricycle is not located on the main axis, like in motorcycles. It is placed between the rear wheels, because of this, when accelerating quickly, the tricycle easily rears up. But this is a much safer event than on a motorcycle and adds adrenaline and entertainment to the trip.

Engine

As a motor, you can use a native motor from the Urals or take a car engine. The main parameter of choice is its capacity between the rear wheels. Be sure to securely fasten it in at least three places. Most often, if the power unit is in good condition, then you don’t even need to do anything with it. And if the engine is old, then you can replace the radiator or some other elements.

Depending on the engine you choose, you will also have to change the exhaust system by installing one muffler for each cylinder.

checkpoint

When converting a motorcycle from the Urals into a tricycle with your own hands, the gearbox is usually installed on the left side, because you usually need to hold the steering wheel firmly with your right hand. You'll have to think a little about how to connect it to the engine, because now the gearbox will be located at a much greater distance from it.

Suspension

The standard motorcycle suspension will have to be redone due to the fact that the load on the wheels in the Ural moto tricycle is distributed differently.

This is done using two consoles and two large springs (aircraft springs are ideal, but car springs will also work). The consoles are connected by levers through which the front axle passes.

Powerful springs are needed because when moving, a huge load is placed on the front wheel and suspension. The remaining springs can be left as standard motorcycle springs.

Battery

A separate frame is usually welded under the battery, which is attached between the engine and the driver’s seat. All the main details are thus arranged in one place. And if you attach panniers to the tricycle, they will completely hide all the important elements.

Coloring

Since a do-it-yourself tricycle based on the Urals is assembled from different parts, as well as other motorcycles and cars, all the parts turn out different and therefore need painting. After painting, it is advisable to apply a clear varnish and polish. And metal elements are chrome plated.

When creating a cargo tricycle with your own hands from the Urals and parts of a VAZ-2101 car, the easiest thing will be to install a regular bridge and make a car suspension with shock absorbers from the Urals.

The bridge from the VAZ-2101 is turned over, after welding the differential. This is reflected in the handling – the steering wheel is quite difficult to turn, however, the trike’s cross-country ability increases.

The driveshaft is shortened and welded to the fork on the final drive and connected to the axle through a rubber coupling. It is better to take the original Uralov clutch, in this case the transmission will be softer.

To avoid bending the cardan drive, you can move the engine to the left by 7-9 cm, or move the axle to the right or increase the wheelbase.

It is better to leave the engine as a whole unchanged, but instead of two carburetors, make one Chinese one. And for forced cooling, use an air filter from Izh.

Additionally, to cool the engine when operating in difficult conditions, you can install two fans and run them separately if necessary.

Pros and cons of the design

How to make a tricycle from a Ural and ZAZ-968 motorcycle

The front fork works like in the Urals, a lever system is used and the front axle is located between the transverse arms.

When creating a trike from the Urals and a ZAZ-968 car, the rear part remains practically unchanged, like a car. Only a muffler, oil cooler and air filter are added there. The gearbox and engine are also original to ZAZ. The engine is mounted as before, and the gearbox is placed on the left.

In general, there is not much to change.

DIY assembly steps

At the very beginning, it is removed from the car rear axle.
A beam is attached to the cut.
Mufflers, an air filter, an oil cooler and pipes are installed on the rear wheel axle. If you use engines from the 90s, then all these elements will already be installed.
A frame is being made that will be the basis of the tricycle, so it is necessary to make it strong and reliable.
An extended front fork is manufactured by welding with shock absorbers attached to it. Lengthening occurs by replacing the fork rods with longer ones or by welding more tubes to the Ural fork.
Welds the frame and rear axle of the car, forming a solid structure.
The fork is connected to the frame by welding, just like with rear axle ZAZA.
After this, the seats, gas tank and other elements are attached.
Finally, the new tricycle is painted and chromed.

The design of this homemade swamp rover so simple that almost any car enthusiast can repeat it in his own garage. The basis of the swamp vehicle is the IZH Planet 3 motorcycle. IZH Planet motorcycles often become donors in all-terrain homemade vehicles, this is primarily due to the endurance and unpretentiousness of their engines.

The main feature of this homemade swamp vehicle is that when constructing it, turning work is reduced to a minimum. I only had to contact the turner once to cut out a seat on a 50 tooth sprocket in order to fit it onto the differential of the Moskvich axle.

Swamp Walker Bridge

The bridge was taken from a Muscovite and modernized. We cut out the bearing mounts from the doll with a grinder, then welded the yoke to the bridge stocking (if it is not welded, the stocking will warp when you cut it in half), then cut the stocking itself in order to secure the sprocket. The chain tensioner was also borrowed from the combine.

Swamp buggy wheels

The KF-97 cameras are used from the agricultural trailer of the T-150 tractor. The tire for such a tube wheel is the same tube, only cut to a smaller diameter. First, the “tire” is put on, then it is tightened with belts. The transverse harnesses turned out to be 1.02 m long, and the longitudinal strip was 3.5 m long. The width of the longitudinal strip is 30 centimeters. The transverse belts with the longitudinal strip are connected using bolts.

Swamp vehicle disks

The basis was taken from cornfield disks, cut in half using a small grinder and extended by 30 centimeters with steel plates welded between the disk halves (6 plates in total). The disc is covered with a chamber from a VAZ car, cut to a larger diameter. Since the disks were used from a Niva, and the axle from a Muscovite, the rear disks at the mounting points had to be trimmed.

Frame, brakes and transmission

The motorcycle frame has been lengthened and strengthened. To prevent the pendulum fork from “walking”, it was welded. The chain and sprockets are borrowed from the combine. Their ratio is 2 to 1. A small star with 25 teeth, it is attached to the drum using eight hardened 10-point bolts. A large star with 50 teeth. Brake system The swamp vehicle is no different from any other, so the brakes are left unchanged. But the drum was modernized to accommodate sprocket mounts.

Fork

The length of the fork stays of this swamp vehicle is 800mm, while its width is approximately 700mm. The front wheel axle was used from a donor - an IZh motorcycle. On one side, an extension pipe 500 mm long is welded to the axle. This pipe is inserted into a modernized Izhevsk drum screwed to the wheel. On the other hand, the axle is screwed into the same mount as on the fork leg. The mount was cut off from the shock absorber and welded to the feather (it is not visible in the photo since it is inserted into the pipe and welded).

The fork is attached to the steering wheel of the swamp vehicle quite simply. 2 pipes are inserted into the shock absorber mount.

Engine for all-terrain vehicle

Engine from a motorcycle IZH-Planet 3 with air forced cooling from a motorized wheelchair SZD (popularly “Invalidka”). The crankshaft is the original crankshaft - the planetovsky one, and not the SZDshny one, since the seat for the generator in the SZDshny one does not fit (it is larger), and the swamp vehicle has an Izh 6v ignition coil.

Tricycle body

Watch this video short description and Test drive of a 200 cc tricycle. At the bottom of the article it is indicated where you can find many videos that tell you how to make such a tricycle with your own hands. The beginning of the story with the assembly of this cargo bike can be seen on our website. This vehicle is equipped with a 200 cc engine with 6 and a half Horse power. The penny's four-speed gearbox is connected to the engine via a centrifugal clutch. The gearbox contributes to the best distribution of forces that are necessary for the operation of the tricycle. Since it was assembled in makeshift conditions, most of the spare parts were either used or new from a metal warehouse. Therefore, in the front part of the frame, the wheels are taken from Soviet mopeds.

The big advantage of this vehicle is the practical independent suspension. She's made of rear shock absorber from the Izh motorcycle. The front part is made of silent blocks. There are two fasteners on the rear main rail with which the body is secured. The main source of electricity in this tricycle is the generator from the Belarus tractor.

The entire history of the tricycle’s assembly can be viewed on YouTube, the SEREGA channel. TV.

Homemade tricycle IZH Jupiter-5

This tricycle based on Jupiter-5 was assembled by the village “homemade craftsman” Vitaly Borovskoy. Such wheel formula allows the motorcycle to behave stably in complete off-road conditions, which provides quite comfortable driving conditions in contrast to its two-wheeled counterparts.

The motorcycle remains practically unchanged, only the rear wheel is sent for replacement, instead of which a gearbox with axle shafts from the Ant cargo scooter is installed. But in this case, the author took a rather unconventional path and made homemade axle shafts from scrap, ordering splines to be bored to the standard size from a familiar turner .

Rear wheels and hubs from Domestic car VAZ, in the winter and snowy seasons, for better traction with the road surface, the author puts chains on the wheels, thus the cross-country ability of the tricycle increases many times over.

It is advisable to install forced air cooling, because the load on the engine with two rear wheels is slightly higher than in standard. The problem of overheating of aluminum cylinders of a motorcycle engine is solved by installing an electric motor with the ability to pump air (motor from car heater) is connected to the on-board network of the tricycle and air is supplied to the cylinder heads through corrugated pipes.

So let's take a look design features homemade tricycle assembled on the basis Soviet motorcycle Jupiter-5

The tricycle is stable and you can easily ride it off-road. Putting the chains on rear wheels cross-country ability increases.

Having settled the motorcycle in the spring snow along the very axle shafts, the movement still continues, but the main thing here is not to overheat the internal combustion engine until forced cooling is installed.

He doesn't care about the spring thaw.

Some information on the caracat, although everything is clear from the photographs, but it may still be interesting. The engine is from an IZH Planet motorcycle, the left cover with a fan is from an SZD disabled person. The standard electrical equipment was replaced with Voskhodovskoe, which does not require a battery and is much more reliable since it has a chroll sensor instead of cams.

UAZ differential and two long UAZ axle shafts. The axle shafts are shortened since the karakat karakat would turn out to be very wide. The original hubs are cut and pressed from Moskvich ones, since the wheels are made on the basis of lighter Moskvich wheels.

The motorcycle wheel disk is halved and a disk for the Bel-79 is made on its basis. In general, two sets of wheels were made, one based on Bel - 79 for mud, one based on tubes for swamps. Upon completion, an unexpected thing emerged: the tube wheels turned out to be somewhat heavier. This year the summer was dry and on the factory wheels we drove through the swamp without any problems; I haven’t “put on” the tube ones yet.

The frame is reinforced with gussets, at the bottom at the engine mount and in the fork mount area. A bronze bushing is inserted into the fork mount for strength, since even without such loads as in the swamp near IZH, the bearings break in this place. The body is made of sheet aluminum and aluminum corner with rivets:

The price of the karakat turned out to be very decent, but this is because a lot had to be redone during the work, since there was no experience in manufacturing just such devices. along the way they decided on different technical problems. The design mainly used only new parts and materials, which is why the price was high. The device is being modified as it goes into use; it has been out through the summer and half of the fall through mud swamps, etc. no problems so far. Below are photographs of the making of this all-terrain vehicle.

The caracat's cross-country ability is excellent, it rushes through the swamp as it should, the engine is high-torque and even with a load it moves confidently through a completely off-road swamp. Very maneuverable and well controlled, of course not like a regular motorcycle, but quite normal and not heavy. In the north of the Omsk region and in Tyumen it is very rare to see a four-wheeled carakat; three-wheeled ones have been tested by time, and they are simpler in design than four-wheeled ones, less iron and components, which means more reliable.

And this caracat is, so to speak, the prototype and predecessor of this caracat.

Checking the caracat's buoyancy, as you can see, it floats on the water and not badly. There is a current on the river, so I tied it with a rope; when crossing a river, we usually tie such devices to a motor boat and then cross it that way.

It took 63,000 rubles to build and finalize this karakat, this price was due to the fact that everything we needed for its construction was purchased new, even the smallest thing, the work of a turner and so on. The engine was overhauled, replacing the piston, we bought a left cover with cooling from a disabled person and more.
