Abstract
A twin mass flywheel which has an input flywheel mass (11) arranged to be coupled to an engine, an output flywheel mass (12) arranged to be coupled to a drive-line, a main rolling bearing (14) for mounting the flywheel masses for relative rotation and having inner (14B) and outer (14A) race members with rolling bearing elements therebetween, and a torsional vibration damping means (17) acting between the masses to oppose relative rotation. At least one of the bearing races is located axially relative to one of the flywheel masses by an annular retaining member (25, 29) which is secured to said one flywheel mass and engages a circumferential groove (26, 30) in the bearing race. Other bearing retaining arrangements are disclosed including the use of tapering races.
