    摘要: A dual-mass flywheel comprises a primary mass (7) which is adapted to be fastened to a crankshaft (3) of an internal-combustion engine concentric to an axis of rotation (1) and a secondary mass (9) which is mounted for rotation relative to the primary mass (7) around the axis of rotation (1). The secondary mass (9) is coupled in a rotationally elastic manner to the primary mass (7) by a torsion-damping arrangement (19). The primary mass has two formed sheet-metal parts (35, 37) which define a cavity (47) to accommodate springs (17) of the torsion-damping arrangement (19) and is provided with supplementary masses in order to increase the moment of inertia. The supplementary masses may be made up of extensions (45, 63) of the formed sheet-metal parts (35, 37) or of additionally welded-on mass-rings (67). In particular, the supplementary masses are located in a region which is generally radially outwardly of the secondary mass (9).
