Abstract
A novel arrangement of a limited slip differential assembly comprising a differential case housing a friction clutch assembly provided within a differential case for selectively restricting differential action and a hydraulic actuator assembly including a piston assembly and a bi-directional gerotor pump. The piston assembly includes a hydraulic piston disposed in a piston housing forming a pressure chamber. The piston housing is provided with a removable bleed plug defining a flow restricting bleed passage. The bleed plug is accessible from the outside of the differential assembly without disassembling thereof through an access hole in the differential case. By appropriately selecting a flow area of the bleed passage, the limited slip differential assembly may be tuned to define application rate of torque transfer of the friction clutch assembly.
