Almost from childhood read the magazine “modelist-Konstruktor”. It has taught a lot of information about new designs, interesting ideas. Inspired by the publication in the journal, while still a high school student, remade old bike in all-terrain vehicle on low-pressure tires, then made a snowmobile with a crawler gear. And still with great pleasure interested in technical creativity.
To date, gained sufficient experience (as I believe) in the production of different capacity, design and purpose tractors.
One of my machines — microtracker “Bee”. So I called him for trouble-free performance, and more — for small dimensions and good maneuverability.
But perhaps the main advantage of microfracture “Bee” — simplicity of design and nedvizimosti components and assemblies. However, some vehicles which used components and assemblies, have become rarities (for example, “Volga” GAZ-21, which is taken from the rear axle), but there are many other, more modern, but also appropriate. Yet it should be noted that for self-made designs is now easier to find car engine than a motorcycle.
The basis of microstructure — welded frame made of pipes of square section 40×40 mm and a wall thickness of 2 mm and angle of angles of the same size. The frame is flat, except for a U-shaped strut to the steering column and the supports for the seat. At the rear of the frame rails welded to the stockings of the rear axle.
As the engine microfracture used the power unit of the motorcycle “IZH Planeta 3”. Its one-cylinder (with a volume of 350 cm3) two-stroke engine power 17 HP runs on a fuel mixture of gasoline and engine oil ratio is 50:1. As is known, motor power unit is a motor, interlocked with the clutch mechanism and gearbox.
Set the power unit on the frame across it, and for better cooling of the cylinder head is rotated 90°. Cooling, although still air is now forced from the home-made fan-impeller. The fan motor serves as a generator from the car ZAZ-968 (Zaporozhets). For work in hot weather provides for the installation of one additional fan.
The muffler of the engine is homemade, made out of the cavity of the car “the Zhiguli”.
The start of the engine is kick-starter. Only now the lever is not mounted directly on the output shaft, and acts on it via a chain drive. Another chain transmission includes in the transmission — it transmits the rotation from the output shaft of the power unit to the input shaft additional the gearbox (transmission). The input shaft is elongated and passes under the sump. On the extended end of the dowel is installed sprocket, and the shaft end rests on a conical bearing mounted on the crossmember of the frame. The chain tension is done by lining of extra washers under the attachment points of the powertrain to the frame.
PPC is used from the UAZ-452, although it is better for this purpose would be the same unit from the UAZ-469. In the absence of the latter had to extend the scale of inclusion of the first and rear gears and install the two switching levers: one on the 3rd and 4 th gear and the other on the 1st, 2nd and reverse. Now switch handle and transfer the power unit.
Thus, microtracker has 16 forward gears and 4 speed — reverse that provides a wide range of traction characteristics.
