Abstract

A limited slip differential mechanism of the speedsensitive type having a rotatable casing and gearing supported within the casing adapted to drive a pair of relatively rotatable output elements including a friction clutch mechanism associated with the gearing and the casing to resist relative rotation. The limited slip differential includes an actuator for the clutches, the actuator being associated with a fluid pump mechanism and the fluid pump mechanism being mounted within the actuator. The fluid pump is carried by the actuator and has an input or drive shaft driveable by a side gear of the differential and the actuator is carried by the casing whereby relative rotation between the casing and the side gear will create fluid pressure to activate the actuator and apply the clutch to resist relative rotation.
