Patent ID: 8739953

Claim:
An actuating assembly for optionally connecting a driving axle in the driveline of a motor vehicle, comprising: a pump for generating a hydraulic pressure; a first hydraulic actuating unit which can be loaded by the pump with a hydraulic pressure against a counter force, wherein in a hydraulically loaded condition the first hydraulic actuating unit forms a pressure accumulator in which a pre-pressure is stored, by which pre-pressure a first coupling in the driveline of the motor vehicle is held in an open position wherein the first coupling is closed in a hydraulically unloaded condition of the first hydraulic actuating unit; a second hydraulic actuating unit which can be loaded with the pre-pressure stored in the first hydraulic actuating unit and which can also be loaded by the pump with hydraulic pressure, wherein by loading the second hydraulic actuating unit, a second coupling in the driveline of the motor vehicle is closed for transmitting torque.
