A rotary vibration damping arrangement, preferably for the drivetrain of a vehicle, comprising at least one deflection mass pendulum unit (72) having a carrier (12) which is rotatable about an axis of rotation (A), having a deflection mass (34) which is deflectable with respect to the carrier (12) in a circumferential direction about the axis of rotation (A), having a deformable restoring element (42) which is or can be supported with respect to the carrier (12) in a carrier support region (62) and with respect to the deflection mass (34) in a deflection mass support region (64), wherein a deflection of the deflection mass (34) from a basic relative position with respect to the carrier (12) in at least one direction effects a deformation of the restoring element (42), having a support element (16) which is mounted in a radially movable manner on the carrier (12) and which provides the carrier support region (62), wherein, as a result of a movement of the support element (16) on the carrier (12), a spacing between the carrier support region (62) and the deflection mass support region (64) can be varied and the support element (16) is preloaded in the direction of a radially inner base position and, in the event of rotation of the carrier (12) about the axis of rotation (A), can be displaced radially outward proceeding from the base position under centrifugal force action counter to the preload, is characterized in that, in at least one rotational speed range, a radial spacing of the support element (16; 16') with respect to the base position increases in degressive fashion with increasing centrifugal force action, and/or in that, as a result of centrifugal-force-induced displacement of the support element (16), a spring stiffness of the restoring element (42) increases in progressive fashion at least in one rotational speed range. |
