Patent ID: 7926637

Claim:
A device for damping vibrations comprising a torsion vibration damper with a primary component and a secondary component, coupled together through a torque transfer device and a damping coupling device, wherein the torque transfer device includes a ramp mechanism for converting a rotation caused by an induction of an input element at one of the primary component and the secondary component into an axial force F axial proportional to the input element, wherein the axial force acting upon the other one of the primary component and secondary component is converted into a torque to be transferred, wherein the torque is supported by a device generating an opposing force F axial-opposing , opposing the axial force F axial at the other one of the primary component and secondary component, and wherein the torque is adjusted to a predefined mean input moment to be transferred; and a conversion device converting an occurring force difference between the axial force F axial and the opposing force F axial-opposing directly into a control variable Y for operating an actuation device in the device for damping vibrations for changing the opposing force F axial-opposing .
