ABSTRACT:
A vehicle with a transmission shiftable in steps by means of friction clutches includes starting unit at the input or output of the transmission comprising a planetary gear having several components, wherein a first of the components is driven. A braking device has at least one brake member connected with a second of the components for rotation therewith, fricton bodies for braking the brake member by dry frictional contact, and actuating means and cooling means for the friction bodies. An actuating system is provided for the transmission and the starting unit which, in a first mode of actuation, holds the brake member fixed on a stationary structural member by means of the friction bodies during automotive operation, and in a second mode of actuation, slidingly brakes the brake member when starting the vehicle. The actuating system in the first mode of actuation briefly releases the brake member from the stationary member during the shifting process so as to suppress any shock produced during shifting.
