摘要： A hydraulic coupling is disclosed for use in motor vehicle driveline applications to rotatively couple a pair of rotary members. The hydraulic coupling includes a multi-plate clutch assembly operatively connecting the two rotary members and an actuator assembly for actuating the clutch assembly in response to and as a function of speed differentiation between the two rotary members. The actuator assembly includes a hydraulic pump, a piston disposed in a piston chamber, and a fluid control system for controlling the fluid pressure supplied to the piston chamber by the hydraulic pump to control the clutch engagement force exerted by the piston on the clutch assembly. The fluid control system includes a pressure relief valve operable for limiting the fluid pressure in the piston chamber to a predetermined maximum pressure value. The fluid control system also includes a thermal unload valve operable for releasing the fluid pressure within the piston chamber when the fluid temperature exceeds a predetermined maximum temperature value.

摘要： A hydraulic coupling including a multi-plate clutch assembly operably connecting two relatively rotatable members and an actuator assembly for actuating the clutch assembly in response to speed differentiation between the two rotary members. The actuator assembly includes a hydraulic pump, a piston disposed in a piston chamber, and a fluid distribution system including a first flow path for supplying hydraulic fluid from a sump to the hydraulic pump and a second flow path for supplying hydraulic fluid from the hydraulic pump to the piston chamber. Hydraulic pressure in the piston chamber controls the magnitude of the clutch engagement force exerted by the piston on the clutch assembly. The fluid distribution system further includes a third flow path between the piston chamber and a clutch chamber. A control valve assembly is located in the third flow path and provides a flow control function for regulating the fluid pressure in the piston chamber and supplying fluid to the clutch chamber for cooling the clutch assembly. The control valve assembly also provides a pressure relief function for limiting the fluid pressure in the piston chamber to a predetermined maximum value, and a thermal unload feature for venting the piston chamber when the fluid temperature exceeds a predetermined maximum value.

摘要： A driveline component with a first drive member, which is rotatable about an axis, a second drive member and a clutch. The second drive member has a hub, which is supported on the first drive member for rotation about the axis, and a transmission portion. The transmission portion, which is configured to engage a flexible power transmitting member, is disposed about the hub and aligned to a transmission axis that is generally perpendicular to the axis. The clutch has a spring and a set of interleaved clutch plates having portions that are coupled for rotation with a respective one of the first drive member and the second drive member. The spring generates a force that is transmitted through the hub such that the clutch plates frictionally engage one another. The location of the transmission portion relative to the transmission axis is unaffected by wearing of the set of clutch plates.
