Abstract
The friction disc clutch for a motor vehicle driven by an internal combustion engine comprises a flywheel which is driven through a rotationally elastic element by the crankshaft of the internal combustion engine. The mass-spring system of the drive path of the clutch is so dimensioned that natural vibrations occur in or below the idling rotation rate range of the internal combustion engine. The rotationally elastic element can be bridged over for rotation rates in the range of and below the idling rotation rate in order to prevent resonance effects in idling and in the starting of the internal combustion engine. The bridge-over clutch can be formed by a pinion of the starter motor. Alternatively, centrifugal clutches can be used.
