An unconventional rubber torsional vibration damper with ...

Rubber torsional dampers with one degree of freedom are a long-time proven tool for vibration damping in crank mechanisms, especially for passenger cars. Their advantages include, in particular, a relatively simple design and low production costs. The viscoelastic coupling of the damper ring with the basic dynamic system is realized by a rubber spring made of natural or synthetic rubber.
