Abstract:
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.
