The transmission and the main transfer are located at Audi 80 as almost at all front-wheel cars, in one general case.
The torque from the engine gets to the main transfer through one small and one big gear wheel. The differential case is fastened to a big gear wheel. In this case there are four conic gear wheels which are in gearing from which two are connected with the leading half shafts.
Until the car moves directly, both forward wheels turn with a frequency of a big gear wheel of the main transfer. Conic gear wheels of the differential rotating at the same speed, on the contrary, stand. When passing turn the external wheel has to pass longer way, than located in turn. Then conic gear wheels begin to work: more bystry rotation of an external wheel and its conic gear wheel affects through both satellite conic gear wheels a conic gear wheel on turn inside which respectively rotates more slowly.
This alignment is necessary, otherwise the car on turns would move breakthroughs with the sliping forward wheels. However existence of differential can be also a shortcoming, for example, if one of driving wheels is scrolled on a slippery surface. Then to other forward wheel it is not transferred almost any draft, the car does not start.
