ABSTRACT:
A torque-coupling device comprising a hydraulically actuated friction clutch pack and a gerotor pump provided for generating hydraulic pressure actuating the friction clutch pack. The gerotor pump is selectively actuated by a device external to the gerotor pump and the friction clutch pack, such as an electric motor, friction brake, electro-magnetic clutch, friction mechanism utilizing a magneto-rheological fluid, electro-magnetic brake, etc. The externally driven gerotor pump may be further provided with torque-multiplication gearing, and/or an electronic controller to modulate the actuation of the pump in order to provide flexible control of the hydraulic pressure generated by the gerotor pump.
