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.
Claims4
Flywheel device for internal combustion engines comprising a first flywheel mass, a second flywheel mass and spring means acting between said masses for transmitting torque between said masses, said first mass (1) having in the vicinity of its outer periphery a flange portion (50) radially outward of said spring means and axially projecting over at least a portion of the second mass, said flange portion (50) being so dimensioned that a gap is formed between an inner cylindrical surface (50a) on said flange portion and an outer cylindrical surface on the second mass (2), said gap having bearing means (60) disposed therein.
