Abstract

A clutch disc as used e.g. in motor vehicle clutches comprises a hub member and a friction lining carrier. The friction lining carrier surrounds the hub member and is mounted thereon for angular movement with respect to the hub member about the axis of rotation of the hub member. A torque is transmitted from the friction lining carrier to the hub member by two groups of torque transmitting springs which are arranged in series. A first group of torque transmitting springs is provided between the hub member on the one hand and an intermediate torque transmission unit on the other hand. A second group of torque transmitting springs is provided between the intermediate torque transmission unit on the one hand and the friction lining carrier on the other hand. Each torque transmitting spring is received by radially aligned openings of three respective torque transmitting sleeves.
