Dynamics of movement on the dry road

There are no doubts that the torsen-differential acts correctly and with sense at a bad stseplyaemost on the road. Therefore the explanation of that occurs in Audi Quattro transmission on the dry road here is still given: 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 regard the torsen-differential tells bigger driving effort of a back axis (because of their smaller number of turns) that supports the necessary tendency to turn inside.

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