ABSTRACT:
A clutch disc arrangement for use in friction clutches of automotive vehicles has a hub which carries two ring-shaped guides flanking a ring-shaped partition secured to a radially extending flange of the hub. A clutch disc, which carries the friction coatings, is installed between one of the guides and the partition, together with a first friction generating unit cooperating with one or more coil springs acting between the guides and the clutch disc to oppose rotation of the clutch disc from a neutral angular position relative to the hub. A friction disc and a second friction generating unit are installed between the partition and the other guide, and the friction disc cooperates with additional coil springs, acting between the friction disc and one or both guides, to oppose certain advanced stages of rotation of the clutch disc relative to the hub. The second friction generating unit has a friction pad between the friction disc and the partition, and the first friction generating unit has a split ring which is surrounded by the inner marginal portion of the clutch disc and surrounds a distancing ring of the hub and abuts against the partition.
