Abstract
A torsional vibration damping device for rotating clutch disks which interact with internal combustion engines includes two coaxial cover disks which are held together and are rotatable about an axis of rotation within a fixed angular range relative to an internally located part. A number of torsion springs are circumferentially arranged between the cover disks and the internally located part which may comprise one of an intermediate disk, side disk, spring, drive disk. The cover disks are axially loaded by a spring force in opposing directions and a distance between the cover plate is fixed by axial distance pieces which are connected between the cover plates. The cover disks and the internally located part are arranged on a hub furnished with splines. At least one stop surface is configured on the external splines of the hub so that the internally located part is supported in the axial direction against the stop surface for axially securing the hub.
