Abstract
A differential gear unit includes an annular ring gear having a rotational axis in an axial direction; side gears respectively distribute torque to drive shafts; differential pinion gears are rotatably arranged on a pinion pin, where the pinion gears respectively engage the side gears. A decoupling element inside the ring gear is rotatably arranged in relation to the ring gear. The pinion pin is connected to and extends diametrically across the decoupling element. A clutch sleeve slides relative to the ring gear and the decoupling element. The clutch sleeve, upon axial displacement, disconnects the ring gear from the decoupling element in a first position, allowing rotational movement of the decoupling element relative to the ring gear; connects the ring gear to the decoupling element in a second position, preventing the rotational movement of the decoupling element; and connects the ring gear to a park-lock structure in a third position.
