Abstract
A fly-wheel includes a first part and a second part. Both parts are rotatably mounted with respect to the other. Torsional springs are provided in torque-transmitting engagement between the two parts of the fly-wheel. Further, a friction device is provided between the two parts. This friction device is controlled by fly weights and a biasing spring such that below the idling rpm of an internal combustion engine driving the fly-wheel the friction device maintains an increased frictional torque-transmission between the two part.
