ABSTRACT:
A resilient coupling has a hydraulic damping appliance for torsional oscillations. Between a first and a second coupling half there is provided a suspended damping ring, which is not connected in a form-locking manner with either of the two coupling halves, but which forms displacement chambers of different sizes with both coupling halves. In this way the coupling is in a position to counteract torsional oscillations having small amplitudes with weak damping and oscillations having large amplitudes with strong damping. From the kinematic point of view the suspended damping ring is at any one time a component of the first or the second coupling half.
