Те, кто любит часто ездить на рыбалку зимой, very often they face the problem of patency. After all, it is not always possible to directly approach the shore of the river even on an off-road car, and even more so to the fishing site itself. An exit from this situation will be a caterpillar snowmobile. However, the price of such equipment in stores is sometimes not available, and therefore there is a need for the manufacture of such a device with their own hands. In today's article, we'll look at how a homemade snowmobile is made on caterpillars and what it takes to have it.
First of all, you should start with the most difficultelement of the construction of a snowmobile is a caterpillar. Along with the motor it is the main motive element of all equipment. In order to do it, first you need to draw drawings of homemade snowmobiles on caterpillars (approximately as in our second photo).
When "basting" parts of pipes with their cut sideExceed the distance between them. If the displacement is 3 or more millimeters, this will lead to an inconsistent operation of the teeth of the drive gear and the tape itself, which will cause the snowmobile to break through. And this leads to a loss of controllability. This discrepancy can lead to the fact that the tape can simply slide off the rollers.
It is important to respect the dimension of the caterpillar.How long it will be depends on the engine power at which the homemade snowmobile will run. On tracks, it is necessary to calculate the nominal pressure of all equipment on its plane. Thus, the curb weight of the snowmobile relative to the roadway should be no more than 0.4 kg / cm2.
Self-made tracked snowmobileswork normally on tapes drilled with a conventional drill. However, in order for the device to work as long as possible, you need to re-drill the drill to work with rubber. You should first purchase a tool designed for processing wooden surfaces. Do not use metal drills.
With the rest of the units will be easier.For example, such components as axles and rubber wheels, “Buranovskiy” drive sprockets and protected bearings can be purchased at any specialized store. By the way, the wheels are better to buy inflatable. This technique will be softer on the go. Axis can be taken from a simple garden cart (biaxial). If necessary, you can trim or, conversely, expand it to the appropriate values of the technique. If you do not have the opportunity to purchase a drive shaft in the store, you can try to make it on a lathe. When self-manufacturing shaft, pay attention to the fact that in its size it is well accommodated bearings.
She will have the main carrierfunction and hold all parts, including the engine, in one whole. By the way, as a motor, you can use the power plant from a motorcycle with a gearbox. But back to the frame. We will manufacture it from a square steel pipe with a diameter of 25x25 millimeters. At the same time, it should be welded in such a way that it has two longitudinal and three transverse beams. The presence of these parts on the frame will significantly strengthen its design.
Напоследок о том, как установить на самодельный snowmobile on tracks steering mechanism. In the process of assembling a snowmobile it is necessary to make two sleeves here. This will be your steering gear. How it's done? It is necessary to weld a water coupling with 1/3 inch internal thread to the front beam and screw in the branch pipes with an external thread. Nozzles already have a rack ski and welded bipod for tie rod. By the way, you can use skis from the usual children's car "Argamak". But before that, prepare them beforehand for installation: attach the angle brackets of the turntable and cut the metal. This will greatly improve the maneuverability and quality control of the snowmobile at high speed.
