Abstract

A torsional vibration damper (1) with an adjustable resonance frequency. The damper has a support plate (2) arranged on a rotating shaft (3). A flexural spring arrangement (5) is mounted on the support plate (2) with a fixed inner end (6) and extends radially outwardly to an inertial mass (11). A support for the flexural spring arrangement (5) is provided constructed as at least one movable slide element (8) arranged in a radial guide (7). A restoring spring (16) exerts a restoring force on the movable slide element (8) in a direction opposite to the centrifugal force resulting from rotation of the shaft (3). The position of the slide element (8) on the flexural spring (5) is influenced by the centrifugal force and the restoring force. The magnitude of the restoring force is varied as a function of the rotational speed of the shaft such that the position of the slide element (8) moves to automatically adapt the resonance frequency of the torsional vibration damper (1) to the speed of rotation of the shaft (3).
