Dynamics of movement at a dry road covering
That at bad coupling about expensive Torsen-differential operates correctly and witty, it is already impossible to deny. Therefore here further explanation of that occurs in transmission of all-wheel drive car Audi on dry road is resulted: as it was already mentioned, forward wheels pass on turns longer piece of a way, than back because back wheels spin smaller radius.
Proceeding from it, the Torsen-differential tells to the back bridge (because of its lower frequency of rotation) the big traction force that supports the desirable tendency on an input in turn.
If the driver enters into turn too sharply and thus one of back wheels the differential immediately directs more than traction energies to (during this moment) to "slower" forward wheels revolves. Fast reaction of system leads to that more strongly forward wheels now pull, and it stabilises the car. Effect – dynamic properties in a critical range on turns considerably improve.
