Abstract:
A separating clutch for a powertrain includes a rotational axis, a friction pack for transmitting a torque in an engaged state, a damper device having a torsional vibration damper or a centrifugal pendulum, and an actuation device for selectively releasing the engaged state. The actuation device is arranged in an axial overlap with the damper device. The friction pack may include a friction disk, a pressure plate, a counter-plate, a pressure pot, and a disk spring supported between the counter-plate and the pressure pot. The friction disk may have a friction surface and the pressure pot may extend through the counter-plate to contact the pressure plate, radially outside of the friction surface, and the actuation device, radially inside of the friction surface. The actuation device may include a pressure chamber with a pressure piston, and the pressure piston may be axially movable and arranged radially within the friction pack.
