US 2015/0316123 A1 · Torsional Vibration Damper Assembly

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.

A drivetrain for a vehicle, comprising:

at least one torsional vibration damping arrangement having:
a carrier arrangement that is rotatable around an axis of rotation (A);
a plurality of flexible restoring elements;
a deflection mass that is movable in circumferential direction relative to the carrier arrangement, wherein the carrier arrangement and the deflection mass are coupled so as to be rotatable relative to one another via the plurality of flexible restoring elements arranged in circumferential direction and extend from the deflection mass in direction of the carrier arrangement,
wherein each restoring element is deformable around a force application point movable in radial direction under centrifugal force and which is associated with the restoring element,
a preloading spring configured to provide a preloading force acting radially in a direction of the axis of rotation (A) on a movable force application point,
wherein a main axis of the preloading spring and a main axis of the restoring element do not extend coaxially.
