Abstract
It is proposed for the clutch disc of a motor vehicle friction clutch that one of the lateral discs of a torsional vibration damper of the clutch disc be mounted via a radially resilient mounting ring on a cylindrical bearing face of a hub of the clutch disc. The mounting ring has a closed annular part which is fixed radially and axially in a central opening of the lateral disc and, on its internal periphery, has a substantially conical, preferably radially slotted, radially resilient connecting region. On its internal periphery, the connection region is provided directly or via a shaped-on tube region with a cylindrical opposing bearing face which rests substantially without initial tension on the bearing face of the hub. Spacer blocks limit the radial spring path and are used for the non-rotational guidance of the mounting ring on the lateral disc.
