ABSTRACT:
A limited slip differential comprises a differential gear housing in which a differential bevel gear is mounted and which has a journal supported by a rolling contact bearing arrangement in a bearing opening of an axle casing. A locking clutch which operatively connects a half-shaft bevel gear meshing with the differential bevel gear to the differential gear housing, and which lies between an axial abutment immovable relative to the differential gear housing and an axially movable pressure disc, is engaged by means of a pin type pressure member which is adapted to be operated, with the aid of a rolling contact bearing, by an actuator of the axial piston-cylinder type. A half-shaft part is rotationally fixed to the half-shaft bevel gear and passes through the journal. As a constructional simplification, a separate pressure member can be saved by disposing the actuator on the side of the rolling contact bearing arrangement opposite to the locking clutch and also arranging for it to act on a thrust bearing surface, lying axially outside the journal, of the half-shaft part used as pressure member, while the half-shaft part has another thrust bearing surface which acts on the pressure disc on engagement of the locking clutch.
