Rotary oscillation damper device, in particular for motor vehicles, and with such a device equipped with two compositions - damping momentum wheels

摘要

Rotary oscillation damper apparatus, which is, in a composite arrangement between two opposite in relation to each other circumferentially acting elastic means, which is rotatably supported coaxial rotating masses (10, 15), at least one packet of springs between a stop part and an engagement part are pressed together, in each case at one of said compositions are arranged, characterized by at least one group of hairpin springs (40), which is fan-like from foot parts (37, 38) from spreading, which in each case on a radially inner circumference of a distributed foot axes (35), with a generally radially aligned pair of legs (41, 42) which extends along a radially outer circumference in a generally arcuate end pieces (43, 44) spreads.
