摘要： The present teachings provide for a power transmitting component including a friction clutch, a reservoir, a hydraulic ram to actuate the clutch, a motor, and first and second pumps simultaneously driven by the motor. The first pump is in fluid communication with the reservoir and the ram. The first pump is configured to provide hydraulic fluid to the ram when the motor rotates in a first direction. The second pump is coupled to the reservoir and provides hydraulic fluid to the ram when the output shaft rotates in the first direction and a pressure differential between the ram and the second pump is less than or equal to a predetermined pressure differential. The second pump has a displacement greater than the first pump and is configured to provide hydraulic fluid to the ram at a lower pressure and higher flow rate than the first pump.

摘要： A clutched device including an actuator and a clutch. The actuator can include a housing and a piston having a first, second, and third face. The first face and the housing can define a first chamber. The second face and the housing can define a second chamber. The second face can have a greater surface area than the first face. The third face and the housing can define a third chamber, isolated from the first and second chambers. A conduit can couple the first and second chambers. A vent can be coupled to the third chamber. A pump can pump fluid from a reservoir to the first chamber. A valve can selectively inhibit fluid communication between the second chamber and the reservoir. A shift element can be coupled to the piston for common translation and can move a clutch member between first and second positions.

摘要： The present teachings provide for a power transmitting component including a housing, a clutch, a vent, and a dam. The vent can fluidly couple a first and second cavity. The dam can include a door member. Rotation of the outer carrier through a fluid in the second cavity can sling a portion of the fluid toward the vent to cause the portion of the fluid to be transferred from the second cavity, through the vent, and to the first cavity. When the piston is in a first position, the door member can be in a closed position to limit fluid flow from the first cavity to the second cavity. When the piston is in a second position, the door member can be in an open position to allow fluid to flow from the first cavity to the second cavity.
摘要翻译：本教导提供了包括壳体，离合器，通风口和水坝的动力传递部件。排气口可以流体地联接第一和第二腔。大坝可以包括门构件。外部载体通过第二腔中的流体的旋转可以使流体的一部分朝向排气口倾斜，以使流体的一部分从第二空腔通过排气口传递到第一空腔。当活塞处于第一位置时，门构件可处于关闭位置，以限制从第一空腔到第二空腔的流体流动。当活塞处于第二位置时，门构件可以处于打开位置，以允许流体从第一空腔流到第二空腔。
