摘要: A power transmission device includes an actuator having an electric motor driving a pump to supply pressurized fluid to a piston acting on a friction clutch to transfer torque between rotatable input and output members. In one instance, a valve between the pump outlet and the piston selectively traps pressurized fluid acting on the piston without continued energization of the electric motor. A gerotor may be formed from a material having a first coefficient of thermal expansion and a housing formed from a material having a second lower coefficient of thermal expansion to vary pump component clearances as the viscosity of the pumped fluid changes with changes in temperature. A method of controlling the power transmission device includes defining a correlation between pump speed, fluid temperature and fluid pressure, determining fluid temperature, determining pump speed, and rotating the pump to transfer a predetermined quantity of torque.

摘要: A power transmission device includes a rotatable input member, a rotatable output member, a friction clutch to selectively transfer torque between the input member and the output member, an actuator providing an actuating force to the friction clutch and a controller. The actuator includes an electric motor having an output shaft drivingly coupled to a gerotor. The gerotor is operable to supply pressurized fluid to a piston acting on the friction clutch. The controller controls the actuator in response to a four-wheel lock request to provide one of a minimum output torque and an output torque greater than a vehicle requested torque to operate the friction clutch in a locked mode.

摘要: A power transmission device includes a rotatable input shaft, a rotatable output shaft and a ring gear fixed for rotation with the input shaft. A carrier is fixed for rotation with the output shaft. A pump assembly includes an inner rotor supported for rotation on the carrier and an outer rotor encompassing the inner rotor. The outer rotor is in driving meshed engagement with the ring gear. The pump provides pressurized fluid to one of first and second fluid ports. A flow restrictor is moveable to selectively restrict fluid flow relative to one of the first and second ports.

摘要: A power transmission device includes a friction clutch operable to selectively transfer torque between an input member and an output member. An actuator is operable to provide an actuating force to the friction clutch. The actuator includes an electric motor having an output shaft drivingly coupled to a pump. The pump is operable to provide pressurized fluid to a piston acting on the friction clutch. A controller that is switched on and off in response to an ignition signal estimates the temperature of the friction clutch at the time of being switched on based on a time the controller has been off. A method of estimating a temperature of the friction clutch is also disclosed.

摘要: A drive train having an axle assembly with a differential and a multi-speed transmission outputs rotary power to an input pinion of the differential. The multi-speed transmission includes a positive or dog clutch with teeth having staggered heights. The staggered tooth height configuration provides a larger effective engagement area with less tooth lash.
