Abstract

A torsional vibration damping arrangement for a drivetrain of a vehicle, having a carrier arrangement which is rotatable around an axis of rotation, a deflection mass movable in circumferential direction relative to the carrier arrangement, carrier arrangement and the deflection mass are coupled to be rotatable relative to one another via restoring elements arranged in circumferential direction that extend from the deflection mass in direction of the carrier arrangement. A restoring element is deformable around a force application point which is movable in radial direction under centrifugal force and which is associated with the restoring element. The movable force application point is acted upon by a preloading force acting radially in direction of the axis of rotation by a preloading spring. A main axis of the preloading spring and a main axis of the restoring element do not extend coaxially.
