Shock absorbing vehicle flywheel - has two flexible coupled discs capable of limited relative movement with opposed abutting stops

摘要

The flywheel is firmly fixed to an internal combustion engine output shaft and is then firmly fixed to the input shaft (12) of a gearbox, via a clutch (6). Two concentric discs (2,4) can turn relative to each other, limited by one or a series of stops (20). The discs are connected by flexible parts (17). The stop slides on one disc (4) and is returned towards the centre. The other disc also has a stop and an opposed high speed stop, formed by shoulders, which blocks the stop on the first disc.
