ABSTRACT:
An actuating device, specifically for actuating locking differentials on vehicles, having an actuating shaft, a drive unit to drive the actuating shaft, where the drive unit comprises an armature core mounted to the actuating shaft so as not to rotate, and a commutator mounted to the actuating shaft so as not to rotate and/or with an electromagnetic brake unit to slow and/or stop the actuating shaft, where the brake unit includes a brake hub flange mounted on the armature so as not to rotate and having a single- or multi-piece housing tightly enclosing the drive unit and the brake unit, where the free end of the actuating shaft extends from the housing and with a sensor to measure the angle of rotation of the shaft, where the sensor unit includes at least one trigger wheel indirectly coupled to the shaft and at least one sensor scanning the trigger wheel position and coupled indirectly to the housing.
