DUAL-MASS COUPLING FLYWHEEL AND COUPLING, IN ADDITION TO A METHOD FOR THE PRODUCTION OF SAID TYPE OF DUAL-MASS COUPLING FLYWHEEL

摘要

The dual-mass flywheel (101) incorporates a primary mass (103) and a secondary mass (105). The primary mass incorporates a primary disc (107) and a central hub (109). The primary disk incorporates a starter gear ring (113). The secondary mass incorporates a secondary plate (115) moving on a plain bearing on a flange on the central hub. There is a spring-damper device (119) with a friction part (123) and a spring part (121). A primary double disk (125) holds individual coil springs (127). A clutch (149,163) is installed after the damper for reduction of torsional vibrations.
