Abstract
The power shift for vehicles has clutches and brakes in the form of multi-disc clutches which consist of disc sets; instead of the multi-disc brake for the reverse drive range, a form-locking clutch such as a disc synchronization is provided which in engaged state transmits the retaining torque via form locking and in disengaged state is freely rotatable and thus free of loss.
