摘要： One embodiment may include a system for distributing torque between front and rear axles of an all wheel drive vehicle and/or between left and right wheels of a two or four wheel drive vehicle comprises at least one limited slip coupling having a disc package and a piston acting thereon, the piston being actuated by a hydraulic pump assembly. This assembly has an electric motor, a hydraulic pump driven thereby, and a centrifugal regulator also driven thereby, the centrifugal regulator controlling a pressure overflow valve, connected to the oil outlet of the hydraulic pump. The assembly specifically comprises an axial piston pump having a piston drum rotatable in a pump housing and containing a number of reciprocable axial pistons, at least one centrifugal lever pivotally attached to the piston drum, and a valve member connected to the centrifugal lever and being arranged for cooperation with the mouth of an oil outlet bore in the piston drum to form the pressure overflow valve.
