Abstract
An axle assembly for a vehicle. The axle assembly includes an input shaft, a first and second output shaft, and a differential assembly. The axle assembly also includes a clutch assembly with an input member coupled to the differential assembly, an output member coupled to one of the first output shaft and the second output shaft, and a clutch member that selectively couples the input and output members. The axle assembly also includes a pump that supplies pressurized fluid to the clutch to control coupling of the input and output members. The axle assembly further includes a motor that drives the pump. The speed of the motor is controllable in order to change a fluid pressure supplied by the pump. The change in fluid pressure from the pump actuates the clutch member to thereby vary the torque between the first output shaft and the second output shaft.
