Abstract

A torsional-vibration damper comprises three concentric ring elements being a hub ring, a flywheel ring and an elastic ring. The flywheel ring is mounted radially inside the hub ring and inside the elastic ring mounted between the hub ring and the flywheel ring. The operating frequency of the torsional-vibration damper is thereby dependent on anguular speed such that as the angular speed increases, the effective operating frequency of the tornsional-vibration damper is shifted higher by increased stiffening of the elastic link between the flywheel ring and the hub ring due to the centrifugal force.
