Abstract

The flywheel comprises first axially flexible disc 2 mountable on crankshaft 8 and carrying clutch counter pressure plate 4 in a radially outer region thereof. To improve the axial damping effect, degressive second disc 3 is rivetted 7 to the first disc and extends therefrom to bear on the counter pressure plate, generating friction thereagainst. Starter gear 19 is mounted to the counter pressure plate on cams 17 protruding through windows in the first plate. Other arrangements include: an undulating ring (526 Fig. 7) between a reinforcing ring (505) and the counter pressure plate (504) an axially resilient spring ring (750 Figs. 9, 9a,b) between the first disc and counter pressure plate or slots (856 Figs. 10a-e) close to the retaining rivet (813) tongues (1103 Fig. 13) formed from the first disc engaging the counter pressure plate and thermal insulation between counter pressure plate and first disc.
