Multi-plate clutch having thermal expansion compensation means

摘要

A multi-plate clutch 1 includes a flywheel ring 2, a hub flange 6, drive plates 7 driven plates 8, clutch cover assembly 10, and a conical spring 90. The driven plates 8 are contactable with the drive plates 7. The clutch cover assembly 10 presses the plates 7 and 8 so as to be pressed into contact with each other and releases the pressure therebetween. The conical spring 90 has spring reaction force smaller than the pressure load of the diaphragm spring and absorbs the axial deformation of each of the members due to thermal expansion.
