A coupling assembly comprises a coupling which is arranged between a driving gear and a differential drive; a controllable actuator for actuating the coupling; a sensor for determining switching positions of the coupling; and a target element which cooperates with the sensor, wherein the target element is axially moved upon actuation of the actuator; wherein a first coupling part of the coupling is connected to a differential carrier of the differential drive and wherein a second coupling part of the coupling is held in a rotationally fixed and axially movable way relative to a differential housing of the differential drive, and wherein the target element is secured to the second coupling part by a bayonet-type connection.

Coupling assembly with a target element

A drive assembly for a multi-axle driven motor vehicle is disclosed herein. The drive assembly comprises a differential unit having a rotational axis, an input part and two output parts drivably connected to the input part, an externally controllable selectable coupling, and an externally controllable locking coupling. The output parts have a compensating effect among each other. The externally controllable selectable coupling is for drivably connecting the differential unit to a drive source. The externally controllable locking coupling is for locking the compensatory movement between both output parts of the differential unit. The selectable coupling and the locking coupling are arranged coaxially to the rotational axis.
