Abstract
A torsional vibration damper includes a common axis of rotation extending along an axial direction, an input part, an output part, rotatable relative to the input part in a limited manner with torque transmission, and a ramp system. The ramp system includes an axially displaceable component, a plurality of rolling elements for converting rotation of the input part relative to the output part into an axial shifting of the axially displaceable component, and a plurality of energy storage elements. The plurality of energy storage elements are arranged distributed along a circumferential direction, extend along the axial direction, and are elastically deformable in the axial direction.
Claims9
A torsional vibration damper comprising:
- a common axis of rotation extending along an axial direction;
- an input part;
- an output part, rotatable relative to the input part in a limited manner with torque transmission;
- a ramp system comprising:
- an axially displaceable component comprising a first disk;
- a plurality of rolling elements for converting rotation of the input part relative to the output part into an axial shifting of the axially displaceable component;
- a plurality of energy storage elements:
- arranged distributed along a circumferential direction;
- extending along the axial direction;
- and
- elastically deformable in the axial direction
- a first ramp system extending along the circumferential direction and comprising a first group of the plurality of rolling elements arranged on a first diameter between the input part and the first disk;
- and
- a second ramp system extending along the circumferential direction and comprising a second group of the plurality of rolling elements arranged on a second diameter, different than the first diameter, between the output part and the first disk.
