Damper disc unit has first and second rotating elements and spring seats for supporting the spring and gripping, preventing twisting of the elastic element

摘要

The damper disc unit comprises a first rotating element (8) with a spring insertion opening (21), and a second rotating element (5,6) with at least one spring insertion area (11) corresponding to the first spring insertion area. A screw spring (31) inside the spring insertion areas transfers a torque between the first and second rotating elements. A pair of spring seats (34)support the spring and grip in the inner side of the screw spring.
