TORQUE TRANSMISSION DEVICE, CLUTCH DEVICE AND TORQUE LIMITER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a clutch device capable of maintaining energizing force with respect to a clutch disk at a constant level even when the clutch disk is worn, and a torque transmission device such as a torque limiter device.;SOLUTION: In the clutch device 1, a clutch cover assembling body 4 is provided with a clutch cover 41 connected with a fly wheel 2; a pressure plate 42 provided so as to be incapable of relative rotation and capable of axial relative displacement with respect to the clutch cover 41 and sandwiching the clutch disk 33 between the pressure plate 42 and the fly wheel 2; and a diaphragm spring 43 provided so as to be incapable of relative rotation with respect to the clutch cover 41 and energizing the pressure plate 42 in the axial fly wheel 2 side. The clutch cover assembling body 4 is further provided with a cone spring 50 which is a member for energizing the pressure plate 42 in the axial fly wheel 2 side and is combined with the diaphragm spring 43 in series to reduce change in the energizing force with respect the pressure plate 42 when the clutch disk 33 is worn.;COPYRIGHT: (C)2007,JPO&INPIT
