ABSTRACT:
A clutch disc with a torsional vibration damper for motor vehicle clutches, including a hub for non-rotational mounting on a transmission shaft, a hub disc which is located on a toothed portion with a range of rotation on the hub, cover sheets on both sides of the hub disc which are non-rotationally connected to one another and one of which supports the friction linings, energy storing devices for a load damper in apertures of the hub disc and of the cover sheets, an idle damper with cover plates on both sides of a hub flange which is firmly connected to the hub, whereby the non-rotational drive of the two cover plates with respect to the hub disc is accomplished by means of axially oriented tabs of at least one cover plate which are circumferentially engaged without clearance or play in recesses of the hub disc, an axially-acting spring as a part of the load damper, and an entrained or dragged friction device located between one of the cover sheets and the idle damper, consisting of a control plate with axial projections which are engaged in circumferentially larger apertures of the hub flange and are circumferentially offset with respect to the tabs. By means of the spring of the load damper, the cover plate of the idle damper, i.e. the cover plate facing the control plate, can be brought into a non-positive connection with the control plate, and the latter in turn can be brought into a non-positive connection with the corresponding cover sheet.
