Abstract

An axle differential transmission, including: a housing; a differential stage including at least one planetary gear assembly; an input shaft connected to the at least one planetary gear assembly; and a clutch assembly including an actuator, at least one first clutch plate non-rotatably connected to the input shaft, at least one second clutch plate non-rotatably connected to the housing, and a one-way clutch including at least one wedge clutch plate. For a initial drive mode, the actuator is arranged to compress the at least one first clutch plate, the at least one second clutch plate, and the at least one wedge clutch plate to non-rotatably connect the housing and the input shaft. For a final drive mode, relative rotation between the housing and the input shaft in a first circumferential direction is arranged to non-rotatably connect the housing, the input shaft, and the at least one wedge plate.
