MOTOR VEHICLE FRICTION DISC CLUTCH

摘要

The motor vehicle friction disc clutch comprises two fly-wheel discs (101, 111) rotationally elastically coupled with one another through an under-load torsional vibration damper (109), of which a first fly-wheel disc (101) is secured to the crank-shaft (107). The second fly-wheel disc 111 utilised as counter-presser plate of the clutch disc (117) is secured to the external circumference of a disc part (143) of the under-load vibration damper (109). The disc part (143) is mounted by its internal circumference through a bearing (145) on a separate bearing extension (149) of the first fly- wheel disc (101). In this way the bearing (145) is thermally as well as mechanically decoupled from the fly-wheel disc (111) serving as counter-presser plate. The torsional vibration damper (109) is dimensioned exclusively for operation under load. A torsional vibration damper dimensioned exclusively for idling operation is provided in the region of the hub (119) of the clutch disc (117) and couples the clutch disc (117) rotationally elastically with the gear input shaft (123).
