Abstract
A limited slip differential mechanism for the speed-sensitive type having a rotatable casing and gearing supported within the casing adapted to drive a pair of relatively rotatable output elements including friction clutches 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 the fluid pump mechanism and having a cam thereon operative to reciprocate radial pistons to create fluid pressure. The actuator is connected with one of the output elements for the differential mechanism and the radial pistons are carried by the casing whereby relative rotation between the casing and the output element will create fluid pressure to activate the actuator and apply the clutches to resist relative rotation.
