A drive assembly for a motor vehicle drive train is provided. The drive assembly includes a clutch pack, a hub, a main piston axially movable with respect to the hub to engage the clutch pack and a clutch control assembly nonrotatably fixed to the hub. The clutch control assembly forms a pressure chamber with the main piston. Rotation of the hub causes the clutch control assembly to close an engagement gap of the clutch pack. Pressure in the pressure chamber moves the main piston to engage the clutch pack after the engagement gap is closed.

The invention relates to a clutch device for a drivetrain of a motor vehicle, including a pressure plate which is preferably displaceable in the axial direction of the clutch device, wherein the pressure plate, in a coupled position of the clutch device, presses a clutch disk against a counterpressure plate that can be connected to a crankshaft of an internal combustion engine, and including an actuating device which has a displaceable actuating piston. The displacement position of the actuating piston defines a position of the pressure plate and the actuating piston can be driven by a drive unit of the actuating device in order to displace the pressure plate between the coupled position and an uncoupled position. The drive unit has at least one pump, and the at least one pump is accommodated in a pump seat housing and the pump seat housing is connected to the counterpressure plate in such a way as to rotate therewith.
