A torsional vibration damper in which the hub ring and the flyring are interconnected through vulcanized-in basic resilient elements as well as resilient units made of rubber that are uniformly distributed around the circumference. These consist of columnar first and second resilient elements which at their outer surfaces merge into one another and at their inner surfaces are spaced from one another. The second resilient elements are precompressed by the first resilient elements and, when the torsional vibration damper is not rotating, are spaced at their outer surfaces from the inner surface of the flyring. At a desired speed of rotation, they are caused by centrifugal force to bear immovably on the inner surface of the flyring. This mechanical connection places their spring action in parallel with the spring action of the basic resilient elements.

A process of producing a resilient coupling in a clearance space between two, relatively-movable elements with a polymeric material introduces the polymeric material contactingly into a clearance space between the elements. A portion of the polymeric material is softened at least while in contact with the clearance-space surface for adhesion when solidified thereafter into a resilient body for the coupling, but a portion of the clearance-space surface is arranged to prevent adhesion. The combination provides coupling with guidance of the relative motion.

A vibration-damping clutch disc with a hub from which a drive disc extends. Support rings on opposite sides of the drive disc are joined together by connections that pass through cutouts in the drive disc and are capable of transmitting torque. Intermediate rings are located between a central hub and each of the support rings and are joined to the hub by radially inner elastomeric damper rings. The intermediate rings have flanges joined by connections that also pass through cutouts in the drive ring. Radially outer elastomeric damper rings join the flange of each intermediate ring to the respective support ring, and one of the support rings has an outer flange with a friction ring on it to be pressed against a flywheel.
