Abstract (en)

[origin: WO0111258A1] A twin mass flywheel (10) for use in drive lines has an input mass (11) for connection with an associated engine and an output mass (12) for connection with an associated driveline, these masses being relatively rotatable via a support bearing (13) acting therebetween against the action of a torsional damping means (14, 15, 16, 17) to damp torsional vibrations in the associated driveline. The input mass (11) has a central disc portion (11b) and a separately formed outer annular main mass portion (11c), the outer annular main mass portion having a recess (11e) in which the outer periphery of the central disc portion (11b) is received, and the inner and outer mass portions being secured together (11f) for co-rotation. The outer mass portion (11c) may carry additional mass in the form of blocks (70) located in a volume of an annular zone between the masses which is not swept by linkages (14) which connect the masses (11, 12) and act as part of the torsional damping means.
