Clutch assembly with two hydraulically actuated clutch devices

A hydraulic assembly for an electrically operable, multi-gear axle drive train of a motor vehicle, the hydraulic assembly comprising

• a first clutch device;
• and
• a second clutch device
• for actuating at least one gear selection device of the electrically operable axle drive train;
• a central release mechanism
• with a first central release mechanism piston that is movable relative to a central release mechanism housing, which is fixed non-rotatably to a drive train housing, in a translational manner, wherein a first pressure chamber is defined between the central release mechanism housing and the first central release mechanism piston, into which a hydraulic fluid is introducible and pressurized such that the first central release mechanism piston is moved hydraulically in relation to the central release mechanism housing, and
• with a second central release mechanism piston that is movable relative to the central release mechanism housing, which is fixed non-rotatably to the drive train housing, in a translational manner, wherein a second pressure chamber is defined between the central release mechanism housing and the second central release mechanism piston, into which the hydraulic fluid is introducible and pressurized such that the second central release mechanism piston is moved hydraulically effected manner in relation to the central release mechanism housing;
• the central release mechanism housing has a groove on a radially outer lateral surface thereof, into which a ring segment-shaped toothing element with an outer toothing is inserted and is connected axially secured and for torque-transmission, wherein the outer toothing engages in a corresponding toothing formed non-rotatably with respect to the drive train housing.
