A damper disk assembly having a frictional mechanism including improved friction elements and a spring member for damping buffer with improved spring seats

摘要

In one embodiment, the spring seat 32 is intended to be used at each end of the small coil springs 6 disposed between the power input rotary member and the power output rotary member. Each spring seat includes a receiving surface and a contact surface for receiving the elastic member described above. The contact surface 36 consists of inclined portions with V-shaped cross sections 37, 38 perpendicular to each other. The power input rotary member and the power output rotary member contact each of the slopes of the inclined portions with the cross sections (37) and (38). In this embodiment, the spring seat 40 is separated into a first support portion 43 and a second support portion 44. The orientation of the spring seat 40 together with the respective power output rotary member is the phase of the power input rotary member In the three embodiments, the friction element is made of synthetic resin and includes a friction adjusting element 20. [ The body portion 15a of the friction element is made of synthetic resin and includes a friction surface in contact with the side surface of the sub-plate 6. The friction adjusting element 20 is provided in the friction surface of the body portion 15a by a mold and is intended to alleviate the coefficient of friction thereof.
