Abstract
The invention relates to a force transmission device for power transmission between an input and an output, comprising at least an input and an output, and a vibration damping device disposed in a cavity that can be filled at least partially with an operating medium, in particular oil, the vibration damping device coupled with a rotational speed adaptive absorber, wherein the rotational speed adaptive absorber is tuned as a function of an oil influence to an effective order qeff, which is greater by an order shift value qF than an order q of an exciting vibration of a drive system.

A force transmission device for power transmission between an input and an output, comprising:
- at least an input (E) and an output (A);
- and
- a vibration damping device disposed in a cavity that can be filled at least partially with an operating medium, the vibration damping device coupled with a rotational speed adaptive absorber,
- wherein the rotational speed adaptive absorber is tuned as a function of an oil influence to an effective order qeff, which is greater by an order shift value qF than an order q of an exciting vibration of a drive system.
A method for improving the damping properties of a force transmission device for power transmission between an input and an output, comprising at least an input (E) and an output (A), and a vibration damping device disposed in a cavity that can be filled at least partially with an operating medium, the cavity in particular flowed through by an operating medium of a hydrodynamic component, the vibration damping device coupled with a rotational speed adaptive absorber, wherein the rotational speed adaptive absorber is tuned as a function of an oil influence to an effective order qeff, which is greater by an order shift value qF than an order q of an exciting vibration of a drive system.
