    • 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).
    • 双质量飞轮包括主质量块(7),其适于紧固到与旋转轴线(1)同心的内燃机的曲轴(3)和辅助质量块(9) 围绕旋转轴线(1)的相对于主质量(7)的旋转。 二次质量(9)通过扭转阻尼装置(19)以旋转弹性方式联接到主质量体(7)。 主质量体具有两个形成的金属片部分(35,37),其限定一个空腔(47)以容纳扭转阻尼装置(19)的弹簧(17)并且具有补充质量块,以便增加 惯性。 附加质量可以由形成的金属片(35,37)的延伸部(45,63)或另外焊接的质量环(67)构成。 特别地,补充质量块位于通常在二次质量块(9)的径向外侧的区域中。
