Possibilities of Damping
All vehicles today should preferably use systems which ensure a decoupling at the point of separation of the engine and transmission. Possibilities to remedy the emergence of resonance's on the one hand consists in raising the system damping and on the other hand in using so-called vibration eliminators. As mentioned before, the hydrodynamic clutch or converter conceptually indicates good damping characteristics. The conventional mechanical clutch however requires additional constructive measures.
The left side of the figure shows an elastic add-on disk which acts as a torsional-spring-damper-element. In its simple conventional design, the add-on disk usually does not produce satisfying damper characteristics since the differing amplitudes of vibration cannot be absorbed evenly. In order to improve the characteristics of the elastic add-on disk, elements with multi-level friction characteristics or rubber elements are realized.
