IMPROVED DOUBLE MASS FLYWHEEL WITH SPIRAL SPRING

摘要

A double mass flywheel comprising a primary mass (M1), a secondary mass (M2) and a filtering unit (3) interposed between the primary mass (M1) and the secondary mass (M2) the filtering unit (3) comprising a filtering assembly (F) and a starter assembly (S) reciprocally in series, the filtering assembly (F) comprising at least a first spring and a damper (Tss) reciprocally in parallel and interposed between the primary mass (M1) and an intermediate element (M3) the starter assembly (S) comprising an actuator element (M4) coupled to the secondary mass (M2) by means of the series consisting of an angular clearance (G3) and at least a second spring; lastly the flywheel comprises an idling assembly (I) between the intermediate element (M2) and the actuator element said idling assembly (I) comprising a damper (TG1) and an angular clearance (G1) reciprocally in parallel.
