Abstract

Each clutch disk has a hub area designed to be connected nonrotatably to a power takeoff element and a friction surface area designed to be clamped between opposing friction surfaces. Each clutch disk has a torsional vibration damper arrangement including two cover disk elements connected to the hub area for rotation in common, and a central disk element connected to the friction surface area for rotation in common. The central disk element is or can be brought into torque-transmitting connection with the cover disk elements via a damper element arrangement. The central disk element has a damper element interaction area and, radially outside the damper element interaction area, a friction surface carrier area, which is offset with respect to the damper element interaction area in the direction of an axis of rotation.
