Abstract
The clutch disc for a friction disc clutch has a hub with external toothing engaging an internal toothing of a hub disc with predetermined rotational play. Axially on both sides of the hub disc, there are arranged side discs of an under-load vibration damper. Damper springs of an idling vibration damper are seated in windows of the hub disc radially inwardly of damper springs of the under-load vibration damper. The idling damper springs are coupled with the hub through side discs. The side discs are arranged axially on both sides of the hub disc and coupled non-rotatably with the external toothing of the hub. For the connection of the ends of the idling damper springs with the side discs, separate tabs formed on the side discs are provided. The components of an under-load friction damper can be arranged within or radially outwardly of the region defined by the under-load damper springs. Radially within the region of the under-load damper springs, at least one thrust ring is provided which transmits the force of an axially acting spring of the friction damper and/or centers the hub disc in relation to the side discs of the under-load vibration damper. The idling damper springs are seated in windows which are open to the windows of the under-load damper springs.
