Abstract
Flywheel device for internal combustion engines. The device has a first flywheel mass (1) intended to be connected to the engine crankshaft, and a second mass (2) with a frictional surface (12) designed to carry a clutch cover with associated pressure plate. Torque is transmitted between the masses via springs (40) laid in channels (17) and fingers (5,6,18). Characteristic for the invention is that a third mass (3) separated from the first and second masses is in engagement with the springs (40) to balance centrifugal and reaction forces acting thereon.
