Clutch disk for use in twin clutch of clutch system for transmitting torque from engine crankshaft to gearbox input shaft of motor car, has hub panes rotated in circumferential direction during opposite relative movements of drive plates

摘要

The disk (10) has a hub (22) connected with an output shaft in a torque-proof manner, and a predamper spring (26) acting between a drive plate (12) or another drive plate and the hub. An end of the predamper spring is connected with the hub in a torque-proof manner, and hub panes are connected with ends of a main damper element (30), respectively. The hub panes are rotated in the circumferential direction during two opposite relative movements of the drive plates in the circumferential direction around different angular values.
