A torsional vibration damper comprises a flywheel ring (3) fixed to the outside circumference of a metallic hub (1) by a rubber spring ring (4), the hub (1) being provided on its side facing the spring ring (4) with a firmly adhesive, continuous coating (5) of thermosetting plastics material. The ratio of the average radial thickness (A) of the coating (5) to the average radial thickness (B) of the spring ring (4) lies within the range 0.25 to 3. The thermal expansion of the coating (5), arising during use, effects a radially directed prestress in the spring ring (4) of corresponding size. By this means, the spring ring always has largely conforming spring characteristics independent of the operating temperature. <IMAGE> |
