摘要： 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 (7) having a disc package (15) and a piston (13) acting thereon, the piston (13) being actuated by a hydraulic pump assembly. This assembly has an electric motor (16), a hydraulic pump (17) driven thereby, and a centrifugal regulator (19) also driven thereby, the centrifugal regulator (19) controlling a pressure overflow valve (20), connected to the oil outlet (23) of the hydraulic pump (17). The assembly specifically comprises an axial piston pump having a piston drum (30) rotatable in a pump housing (31) and containing a number of reciprocable axial pistons (35), at least one centrifugal lever (40) pivotally attached to the piston drum (30), and a valve member (44) connected to the centrifugal lever (40) and being arranged for cooperation with the mouth of an oil outlet bore (45) in the piston drum (30) to form the pressure overflow valve (20).

摘要： The present invention concerns a pump coupling or hydraulic actuator controlling one or more limited slip couplings (7, 37) of a distribution system for distribution torque between front and rear axles (3, 5) in all wheel drive vehicles and/or distribution of torque between left and right wheels in two or four wheel drive vehicles. The hydraulic actuator comprises an electric motor (16), a hydraulic pump (17), driven by means of a drive shaft (18) of the electric motor (16), and the one or more limited slip couplings (7, 37). Each limited slip coupling (7, 37) comprises a disc package (15, 40) and a piston (13, 38) acting on the disc package (15, 40), which piston (13, 38) is actuated by means of the hydraulic pump (17). A centrifugal regulator (23, 31) is connected to a rotating part of the electric motor or the hydraulic pump (17), which centrifugal regulator (23, 31) controls a pressure overflow valve, connected to the oil outlet (21) of the hydraulic pump (17). The pressure is controlled by current to the electric motor (16) or by control of the motor speed.
