Dynamics of movement on dry road

There are no doubts that the torsen-differential operates correctly and with sense at bad сцепляемости on road. Therefore here the explanation of that occurs in transmission Audi Quattro on dry road is still resulted: as it was already mentioned, forward wheels on turn pass longer piece of a way, than back wheels as back wheels describe an arch of smaller radius.

In this connection the torsen-differential tells большее приводное effort of a back axis (because of their smaller number of turns) that supports the necessary tendency to a turn inside.

If speed too big and thus one of back wheels is turned, the differential transfers at once big приводную force to slower at present forward wheels. Fast reaction of system promotes that forward wheels pull more strongly, and the car is stabilised. Effect: running characteristics in a limiting range of turn improve.
