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.

Abstract: A clutch disc assembly for use in friction clutches of automotive vehicles has a hub with two spaced-apart annular guides and a mounting flange between the guides. A clutch disc is rotatable relative to the hub from a neutral position and surrounds the flange. The initial stage or stages of rotation of the clutch disc relative to the hub are opposed by one or more friction pads which are interposed between the clutch disc and one of the guides and/or between the clutch disc and the flange. Further rotation of the clutch disc relative to the hub is opposed by a friction disc which is adjacent to the outer side of and is biased against the other guide with the interposition of one or more friction pads.
