Abstract

The clutch disc for a motor vehicle friction clutch comprises a hub and a friction lining carrier mounted rotatably on the hub. A torsional vibration spring means is arranged in the torque transmission path between the friction lining carrier and the hub. A torsional vibration damper comprises at least two friction elements lying axially resiliently flat against one another. One of the friction elements is connected non-rotatably with the hub and the other friction element is connected non-rotatably with the friction lining carrier. One of the friction elements is held displaceably in the radial direction, along the friction face of the other friction element, on the hub or the friction lining carrier. By radial adjustment of the friction element the friction torque can be adjusted and construction tolerances of the clutch disc can be compensated.
