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.
A clutch device for a drivetrain of a motor vehicle comprising a pressure plate that is displaceable in an axial direction of the clutch device, a clutch disk, and a counterpressure plate, the pressure plate in a coupled position pressing a clutch disk against the counterpressure plate that is connectable to a crankshaft of an internal combustion engine, an actuator device having a displaceable actuator piston, with a displacement position of the actuator piston determining a position of the pressure plate, the actuator piston for displacing the pressure plate allowing the actuator device to be driven between the coupled position and a decoupled position by a drive unit, the drive unit comprises two pumps, with the pumps being received in a pump seat housing and the pump seat housing being connected in a torque-proof fashion to the counterpressure plate, the two pumps being circumferentially spaced apart from each other.
