Abstract
Flywheel device for internal combustion engines. The device has a first flywheel mass (1) intended to be coupled to the engine crankshaft, and a second mass (2) with a frictional surface (12) designed to carry a clutch cover with associated pressure plate. Via first and second springs (40a,40b), laid in channel (17), and fingers (5,6,18) torque is transmitted between the masses. In the torque-unloaded state, there is a small play ('s') between the second springs (40b) and the adjacent fingers. When low torque is transmitted (idle), only the first springs (40a) are active.
