SEAT MEMBER, ELASTIC MEMBER ASSEMBLY AND DAMPER MECHANISM

摘要

PROBLEM TO BE SOLVED: To realize a multistage characteristic with a simple structure in a damper mechanism. ;SOLUTION: Plates 12 and 13 have first window parts 51 and second window parts 52 of the same shape. A hub flange 6 has first window holes 53 and second window holes 54 of the same shape respectively, corresponding to the first window parts 51 and the second window parts 52. First elastic member assemblies 30 are arranged in the first window parts 51 and the first window holes 53, and have first coil springs 33 and first seat members 34. Second elastic assemblies are arranged in the second window parts 52 and the second window holes 54, and have second coil springs 36 and second seat members 37. When the first seat member 34 opens a clearance in the rotating direction from the first window hole 53, the first coil spring 33 is not compressed in a small torsional angle region, where the second coil spring 36 is compressed in the torsional characteristic, but is compressed in a large torsional angle region.;COPYRIGHT: (C)2001,JPO
