VEHICLE FINAL DRIVE UNIT

摘要

A vehicle final drive unit includes a differential and a torque distribution device. The differential includes a differential case (59) and a differential gear set carried within the differential case. The torque distribution device transfers torque between the differential gear set and a side shaft of the vehicle, and may include a clutch (75) and an actuator assembly (100). The actuator assembly includes an actuator and a coupler (116) driven by the actuator. The coupler is selectively moved by the actuator to a first position wherein the side shaft is disconnected from the differential and not actively driven, a second position wherein the side shaft is coupled to the differential gear set, a third position wherein the side shaft is coupled to the differential case and a fourth position wherein the coupler actuates the clutch to couple the side shaft to the differential gear set.
