Selectively controlled limited slip differential

摘要

A differential gear assembly for an automotive vehicle includes a differential housing. A first side gear and a second side gear are substantially axially aligned and spaced apart from one other, each of the side gears being supported by the differential housing for relative rotation therebetween and being adapted to engage an axle half-shaft. A clutch pack is mounted between and interconnects the differential housing and the first side gear. A ball screw assembly is adapted to selectively apply axial force to the clutch pack, thereby locking the first side gear to the differential housing and preventing relative rotational movement of the first side gear and the differential housing.
