The main transfer
The transmission and the main transfer are located at Audi 80, as almost at all front-wheel cars, in one general картере.
The twisting moment from the engine gets to the main transfer through one small and one big gear wheel. To the big gear wheel it is fastened картер differential. In it картере there are four conic gear wheels being in gearing from which two are connected with leading semiaxes.
Until the car moves directly, both lobbies of a wheel turn with frequency of the big gear wheel of the main transfer. Conic gear wheels of the differential rotating in the same rate, on the contrary, stand. At turn passage the external wheel should pass longer way, than located in turn. Then conic gear wheels start to work: faster rotation of an external wheel and its conic gear wheel operates through both satellite conic gear wheels on a conic gear wheel on an inside of turn which accordingly rotates more slowly.
This alignment is necessary, differently the car on turns would move jerky with sliping forward wheels. However differential presence can appear and a lack, for example, if one of driving wheels is scrolled on a slippery surface. Then to other forward wheel it is not transferred almost any draught, the car does not get under way from a place.
