Clutch disc with torsional damper and partial friction elements

摘要

Clutch disc (10) with torsional vibration damping springs (13) which are supported on a driver disc (12). The driver disc (12) is provided with partial recesses (17), to which opposite, partial friction facing pieces (18) assigned to the hub disc (21) are assigned. If relatively large torsional vibrations occur, the friction facing pieces (18) slide up the edges (26) of the recesses (17) and thus bring about a constant or graduated increase in the damping frictional force. <IMAGE>
