Beschreibung
Zusammenfassung:	The present invention relates to an externally controlled lockable differential drive with the load application on its friction assembly being effected via a selectively actuatable rotary drive via a pressure ring. For this purpose, there is provided an actuating ring which is drivable by an electric motor via a pinion and which effects an axial adjustment of the pressure ring. The pressure ring itself cannot be rotatable relative to the housing. End faces of the pressure ring and the actuating ring which face each other are provided with control curves or profiles, which together with interplaced rolling elements, as necessary, displace the pressure ring upon rotation of the actuating ring, and can feature a nonlinear rate of change of the axial component acting on the pressure ring as a function of the angle of rotation of the actuating ring.
