First complete a sketch of the planned design of the snowmobile. This will provide two components of the device: led and lead. The first should consist of the skids, the steering column and shock absorbers. The second part should contain the power plant, the frame, the drive and the driver's seat. However, if necessary, can change the design, adapting it more to fulfill the expected tasks.
Define parts and assemblies of the snowmobile, which you will not be able to do it yourself. You can buy them and roughly estimate the location of the units on a snowmobile, the dimensions of the structure and its individual parts. Approaching the layout professionally manufacture Plaz – the layout of a snowmobile in a life-size plywood or cardboard. Make models of all purchased parts, frame layout and the use of this plasma. After you determine size and arrangement of parts, which are supposed to make yourself.
Independent fabrication frame necessarily implies bending, welding equipment and relevant skills. If all this is not to order the production of frames to the nearest workshop at a pre-drawn drawing. To do the frame myself start by selecting the required tubes. Pipe, taken from motorcycle frames prefer water. Special frame tube, tend to be more durable.
Bend the pipe on the bending as necessary. Before welding assemble the frame, joining parts by spot welding. Perform a preliminary adjustment of elements of the frame and attached thereto parts of a snowmobile. This will allow to avoid mistakes in the design. Final welding spend a single seam, preferably without discontinuities and other flaws. Weld the mounting brackets of the engine, skids, wheel drive, seat, steering column and other parts.
The skids are manufactured in two broad skis. Weld the steering column and secure it to the rails with staples, swivel. A more complex option involves the use of shock absorbers in the suspension of the skis. If the design of the snowmobile provides a wide-set front skis, the shock absorbers are more suitable lever from a motorcycle "Ural". Directly on the handlebar attach the controls from any motorcycle model.
The second part of the snowmobile mount the engine and transmission. They also take from any lightweight bike. As the rear wheel (or wheels) tires, apply low-pressure self-production. They can be made of suitable rims and pneumatic tires cameras. In an inflated condition they are good wheels low pressure. For movement on loose snow binding snegopady located around the circumference of the wheel (wheels).
If the design of the snowmobile imply the existence of a rear wheel, the rear suspension will perform on the motorcycle model. Therefore, in addition to the frame weld the rear swingarm and attach it to the frame via a hinge. Using motorcycle shock absorbers, take suspension of the pendulum. Consider and install a chain drive from the engine to the rear wheel. After adjusting the drive and install the rear wheel.
If you want to install two rear wheels attach to the rear axle shortened type. For this purpose, find the rear axle of the motor scooter cargo "the Ant" or will shorten the bridge from a passenger car. If you use soft wheels low pressure need to the rear suspension partially disappears. The use of motorcycle shock absorbers technically complicates the task. The use of shock absorbers of the automotive type will not make the suspension soft, as they are designed for much more weight than a snowmobile.
Advice 2: How to make a motorcycle with your hands
From what did not make our fathers and grandfathers vehicle! But the self-made motorcycles are relevant in our time. Fans of fast driving exhibitions where they show their work. And, in some cases, such stories are in no way inferior and sometimes even superior to vehicles manufactured in the factories.
You will need
- - an old Bicycle;
- - the fuel tank;
- - the muffler.
Self-Assembly of a motorcycle – a great opportunity to create a vehicle tailored to the individual needs of its owner. To begin, you must mentally construct a motorcycle. Think about what you would like to see, and what functions it must perform.
Sketch drawing of your bike on paper. Simply diagram to facilitate his work on the Assembly.
Now examine the provisions of the document "Technical requirements for motorcycles, scooters and mopeds, made in individual cases." Made with his own hands the bike must comply with these regulations.
The easiest and most versatile option is homemade mini-moped on the base of the bike. If you choose this option, then any bike should have a thick frame and large diameter wheels, then get a reliable vehicle.
Now you can proceed directly to the Assembly of a motorcycle or moped. If design-based bike, add fuel tank, engine and muffler.
Use parts intended only for motorcycles and mopeds. Automotive and other spare parts can only be used in extreme cases. But then you will be able to use this motorcycle in the country.
Assembled from different parts of the motorcycle does not look very nice, so it is better to paint. Before painting clean and degrease the parts of the vehicle. Use moisture-proof and heat-resistant paint to permanently protect parts from effects of the environment and to preserve the attractive appearance of the motorcycle.
If homemade motorcycle will not meet the technical requirements, you will not be able to use it as intended. All parts, including the engine must be strictly series production. Moreover, the engine power should not be more than 60 l/s per ton of motorcycle and less than 12 l/s Frame, and other bearing designs of a motorcycle must be made of very durable materials.
