ABSTRACT:
The clutch disc comprises two side discs firmly connected with a hub, between which there are arranged two intermediate discs rotatable in relation to the hub. Between the intermediate discs there is arranged a middle disc rotatable in relation to these discs, which is connected non-rotatably through tabs with a friction lining carrier. The tabs couple the friction lining carrier with predetermined play in rotation with the intermediate discs. At least two springs with different spring ratings, arranged coaxially one within the other, are seated in windows of the discs. The weaker inner spring is loaded on a relative rotation of the middle disc and the intermediate disc, while the stronger outer spring is effective on a relative rotation of the intermediate discs for the one part and the side discs for the other part. The inner spring forms an idling vibration damper while the outer spring and possibly further such springs form an under-load vibration damper.
