For many years since the entry into force of “Technical conditions” to build a home-made micro cars and sidecars the creators of these machines in their structures often used the main gear of the rocking rear axle and transmission from a wheelchair sidecars of various modifications. All the disadvantages of these mechanisms are stereotypically repeated in almost every home-made, significantly impairing their performance. Traced the pursuit of more utilitarian to fulfill this part of the design, almost nothing or nothing changing in the factory units, and parts and disguised all this slightly redesigned (compared to wheelchair) the body, fenders and other “decorations”.
Unfortunately, with the emergence of a new class of micro cars sport “buggy” traditional solutions were used here. Open circuits, weak transmission (usually a motorcycle), large losses in the main transmission, the abundance bias in mates rotating components of the drivetrain, bad approaches for adjustment and repair, the inconvenience of shift work (especially races) — all this taken together significantly reduced the reliability of micro cars “Buggy-350” and hindered the process of their further improvement. Other prospects were opened to designers in the case of the transmission from the car “Zaporozhets”: it would allow the use of different motors, irrespective of the scheme of arrangement of the cylinders and completely freed from the care chains, clutch, main gear, etc.
However, transmission “plows” are not docked to not only engines of type “Ij” of various modifications having a transverse crankshaft, but with engines of the boxer type. We needed some transitional device, allowing for the lowest power loss and with minimum cost to connect the engine to the transmission “Zaporozhets”.
