Abstract
A flywheel assembly having a first flywheel ring joined to the drive shaft and a second flywheel ring joined to the driven shaft, the two rings being mounted concentrically one inside the other for relative rotation. A spring and a damping system are provided parallel to one another between the first and second flywheel ring to inhibit relative rotation. The damping system is provided with a disengaging device by which its damping action is disabled, such that the spring alone is active, in the event of a relative rotation of more than 30.degree..
