Title:
DUAL CLUTCH
Document Type and Number:
WIPO Patent Application WO/2011/116749
Kind Code:
A3
Abstract:
A dual clutch for coupling an engine-side input shaft with a first transmission-side output shaft (14) and/or a second transmission-side output shaft (16) comprises a first clutch (20) having a first pressure plate (24) for coupling with a first clutch disk (12) connected to the first output shaft (14), said first pressure plate being axially mobile relative to a first counter plate (22). The dual clutch further comprises a second clutch (34) having a second pressure plate (38) for coupling with a clutch disk (16) connected to the second output shaft (18), said second pressure plate being axially mobile relative to a second counter plate (36). A torsional vibration damper (48, 68) is arranged between the input shaft (14) and the first counter plate (22) in the direction of flux of force. According to the invention, the torsional vibration damper is designed as a dual mass flywheel (48) comprising a bow spring (58) for torque transmission extending in circumferential direction, the flux of force being introducible into the dual mass flywheel (48) from the input shaft to the first counter plate (22) radially outwards relative to the bow spring (58) and being dischargeable radially inwards relative to the bow spring (58). The invention allows a simplified design of the dual clutch without significantly increasing the space requirements.
