Abstract
The two-mass fly-wheel for a motor vehicle includes a first fly-wheel (3) rotatable about a rotation axis (1) and containing, axially on one side, a chamber (13) limited by a substantially cylindrical inner circumferential wall (11). A second fly-wheel (7) is coaxially mounted on the first fly-wheel (3). A lid (15) secured on the first fly-wheel (3) seals off the chamber (13) fluid-tightly from the second fly-wheel (7). In the chamber (13) a torsional vibration damper (9) is arranged of which the side disc (23) axially adjacent to the lid (15) is axially clamped in, outside the circumferential wall (11) of the chamber (13), between the lid (15) and an end wall (37) of the first fly-wheel (3). One of the two side discs (21, 23) of the torsional vibration damper (9) is provided, radially within the circumerential wall (11) of the chamber (13), with a plurality of axially protruding noses (55 ) staggered in the circumferential direction in relation to one another, which engage with play in the circumferential direction through openings (57) of a hub disc (19) of the torsional vibration damper and without play in the circumferential direction in openings (59) of the other side disc.
