Torsional vibration dampers are increasingly being installed in the clutch discs of friction clutches. These dampers perform a damping function between the hub and the friction facings of the clutch disc, damping torsional vibrations, which originate from the internal combustion engine and should not reach the driving wheels via the gearbox. These torsional vibration dampers customarily consist of a spring device and of a damping device, e.g. a frictional damping device. At the same time, large angular deflections are increasingly being demanded. For this purpose, it is proposed to provide a path conversion stage between the hub and the facing carrier, it being possible to a large extent to retain the remaining components of the torsional vibration damper and there is likewise essentially no need for changes in relation to the prior art as regards the space provided for the spring device. The path conversion itself can, for example, be effected via two-armed levers or via an epicyclic gear arrangement.
