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 torque transfer device (34) for a motor vehicle includes a clutch (50) for transferring torque between first and second shafts (76, 78). An electromagnetic actuator (98, 102) includes an axially moveable armature (102) for applying an application force to the clutch (50). An actuator control system includes a position sensor (118c) operable to output a signal indicative of a position of the armature (102). The control system determines a target torque to be transferred by the clutch (50) and a target armature position based on a previously determined clutch torque vs. armature position relationship. The control system varies an electrical input to the electromagnetic actuator (98, 102) to perform closed loop control of the armature position.

摘要： A torque transfer coupling includes first and second rotary members. A transfer clutch operatively connects the first and second rotary members. A piston, disposed in a piston chamber, is actuable to engage the transfer clutch. A hydraulic pump in fluid communication with a sump containing hydraulic fluid has a first pump member fixed for rotation with the first rotary member and a second pump member fixed for rotation with the second rotary member such that relative rotation between the first and the second pump members generates a fluid pumping action. A first flow path supplies hydraulic fluid from the hydraulic pump to the piston chamber. A second flow path supplies hydraulic fluid from the piston chamber to a control valve for regulating the pressure of the hydraulic fluid supplied to the piston chamber. The second flow path includes an aperture extending through the second pump member.

摘要： A hydraulic control system for a vehicle includes a brake control unit having a mechanically actuated master cylinder and an electric motor driven pump. The master cylinder and the pump are each adapted to separately provide pressurized fluid to a brake cylinder. A hydraulically actuated drive coupling selectively transfers torque between rotatable input and output shafts. The rotatable output shaft is adapted to drive a vehicle wheel. The hydraulic control unit is in receipt of pressurized fluid from the pump. The hydraulic control unit includes a valve moveable between a first position where the drive coupling is in communication with the pressurized fluid and torque is transferred by the coupling and a second position where the pressure of the fluid in the cavity is reduced to reduce the torque transferred by the coupling.

摘要： A drive axle assembly includes first and second axleshafts and a drive mechanism coupling a driven input shaft to the axleshafts. The drive mechanism includes a differential assembly, a planetary gear assembly operably disposed between the differential assembly and the first axleshaft, a brake and first and second mode clutches. The first clutch is operable with the brake and the planetary gear assembly to increase the rotary speed of the first axleshaft which, in turn, causes a corresponding decrease in the rotary speed of the second axleshaft. The second clutch is operable with the brakes and the planetary gear assembly to decrease the rotary speed of the first axleshaft so as to cause an increase in the rotary speed of the second axleshaft. A control system controls actuation of both mode clutches.
