ABSTRACT:
A hydraulic coupling includes a clutch assembly operatively connecting two rotary members and an actuator assembly for actuating the clutch assembly in response to speed differentiation between the two rotary members. The clutch assembly includes a multi-plate clutch pack alternately connected between the two rotary members within a clutch chamber. The actuator assembly includes a hydraulic pump, a piston disposed in a piston chamber, and a fluid distribution system having a first flow path between a supply chamber and the hydraulic pump, a second flow path between the hydraulic pump and the piston chamber, and a third flow path between the hydraulic pump and the clutch chamber. The fluid delivered to the piston chamber controls engagement of the piston with the clutch pack for controlling actuation of the clutch assembly. Additionally, the fluid delivered to the clutch chamber is used to cool and lubricate the clutch pack.
