Abstract
A clutch disk for a motor vehicle friction clutch is proposed of which the torsional vibration damper, designed for idle running, is arranged radially between a hub and springs of a torsional vibration damper designed for load running. The idling damper is arranged axially between a hub disk and one of the lateral disks of the load damper torsionally elastically coupled to the hub disk. The idling damper comprises an input part, produced from plastics material, which is non-rotatably connected to the hub disk coupled with rotational play but otherwise non-rotatably to the hub. The output part of the idling damper also consists of plastics material and is non-rotatably connected to the hub. Helical springs, couple the output part torsionally elastically to the input part. Pairs of projections, shaped on the input part, enclose the springs between themselves and are supported through the pockets on the hub disk. Additional supporting elements, which engage in openings in the hub disk, are shaped on the outer periphery of the input part. The input part also forms a friction face of a friction device designed for load running. A friction face of a friction device, designed for idle running, is shaped on a tubular attachment of the output part. Entry bevels and catch shoulders are shaped on the projections of the input part for assembly purposes. The components of the idling damper can be oriented, relative to the hub flange, during assembly by means of a guiding tool.
