Abstract
A torque transmission device including a speed-adaptive vibration absorber having an absorber mass that is arranged inside a housing, which is at least partially filled with a working medium. The vibration absorber is designed to compensate for vibration angle-independent and vibration angle-dependent damping effects by the working medium in the operating state.
Claims5
A torque transmission device comprising:
- a housing that is at least partially filled with an operating medium, formed by an oil;
- a speed-adaptive vibration absorber having an absorber mass, which is arranged inside the housing, wherein the speed-adaptive vibration absorber is configured to compensate for vibration-angle-independent and vibration-angle-dependent damping effects as a result of the operating medium in an operating state,
- wherein:
- qb(φ)=qt(φ)−qsu−qsa(φ),
- wherein:
- qt(φ) is an absorption magnitude of the speed-adaptive vibration absorber during operation without the operating medium,
- qb(φ) is an absorption magnitude during operation with the operating medium,
- qsu is a constant absorption magnitude displacement and is substantially constant, and
- qsa(φ) is a function that is dependent on the vibration angle of the absorber mass.
