    Abstract: An actuating assembly for connecting a driving axle in the driveline of a motor vehicle is disclosed. The actuating assembly comprises a pump for generating a hydraulic pressure; a pressure accumulator which can be filled by the pump with a hydraulic fluid for generating a pre-pressure; a first hydraulic actuating unit for actuating a first coupling; a second hydraulic actuating unit for actuating a second coupling; wherein at least one of the two first or second hydraulic actuating units can be loaded by the pressure accumulator with hydraulic pressure and, after the pressure accumulator has been at least partially emptied, can be additionally loaded by the pump, wherein the associated first or second coupling can be actuated in the closing sense. Furthermore, a drive assembly having an inventive actuating assembly is also disclosed.
