Abstract

The invention relates to a clutch disc including an idling damping device and an under-load damping device, wherein the idling damping device is active between two hub parts coupled with each other by a toothing having play in the circumferential direction. In order to avoid the load-change impact, centrifugal weights are provided between the two parts. The centrifugal weights frictionally couple the two parts by means of a self-intensifying effect.
