Actuating assembly

摘要

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.

1. 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.
