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).
A torsional vibration damper having a variable resonance frequency, comprising a support plate mounted to a rotating shaft, a flexural spring arrangement disposed on said support plate, said spring arrangement having a fixed inner end and extending radially outwardly to an inertial mass on said support plate, said spring arrangement further comprising at least one slide element arranged in a radial guide element on the support plate, each said at least one slide element being engaged by a restoring spring which exerts a restoring force on said at least one slide element in a direction opposite to a centrifugal force resulting from rotation of said shaft, said at least one slide element being radially movable in said guide element by said centrifugal force and said restoring force, wherein the restoring force of said restoring spring is varied as a function of the rotational speed of said shaft in such a way that the slide element is positioned to adjust the resonance frequency of the torsional vibration damper to the rotational speed of the shaft.
