Abstract

A torsional vibration damping arrangement, comprises at least one deflection mass pendulum unit with a rotatable carrier, a deflection mass, a deformable restoring element, a supporting element which provides the carrier supporting region, wherein a distance between the carrier supporting region and the deflection mass supporting region can be varied through movement of the supporting element at the carrier, and the supporting element is preloaded in direction of a radially inner base position and is displaceable radially outward against the preloading under centrifugal force action wherein that a radial distance of the supporting element from the base position increases degressively with increasing centrifugal force action at least in one rotational speed range and/or in that a spring stiffness of the restoring element increases progressively at least in one rotational speed range through centrifugal force-induced displacement of the supporting element.
