ABSTRACT:
A torsional damper device suitable for use in an inertia flywheel also serving as the reaction plate of a clutch is provided with arrangements to reduce operating noise. The device comprises coaxial first and second parts which rotate relative to each other to a limited degree. There are two substantially parallel annular flanges on the first part and at least one plate on the second part disposed axially between these flanges. Springs are disposed substantially circumferentially between base members on one of the parts. First engagement devices on the base members cooperate with complementary engagement devices on one of the parts. Second engagement devices on the base members cooperate with complementary engagement devices on the other part. The complementary engagement devices on the one part and/or the other part comprise attached separate members made from an elastomer or synthetic material. This arrangement makes it possible to dispense with accurate cutting out of the flanges and plates of the two coaxial parts.
