Abstract

The torsional vibration damper suitable for the clutch disc of a motor vehicle friction clutch comprises an idling damper, the springs of which are retained in recesses of a toothing which couple the hub of the damper with a disc part, with limited play in rotation. The end faces of the spring lie for the one part on stop edges of the disc part and for the other part on stop edges of two retaining discs which annularly enclose the hub. The retaining discs are coupled non-rotatably, by axial bent-out portions, with a hub disc of the hub, and for assembly are pushed axially on to the hub. The retaining discs can be produced simply and fitted without problem. FIG. 1.
