Damper mechanism for vehicle's clutch disc assembly, has rotary structures which are compressed in positive and negative sides of torsion characteristics, when relative rotation exceeds specific torsion angle

摘要

A pair of parallely arranged elastic structures couple the rotary structures (2,3) together in rotating direction and get compressed, when relative rotation occurs between rotary structures. The rotary structures are compressed in positive and negative sides of torsion characteristics, when relative rotation exceeds specific torsion angle. The friction resistance is generated only when secondary elastic structure is compressed.
