  • Patent number: 5213188
    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.
