ABSTRACT:
A clutch cover assembly 10 is used with clutch friction disks of a dry multi-disk clutch 1, and is provided with a diaphragm spring 30, a clutch cover 28 and a support structure 31. The outer periphery portion of the diaphragm spring 30 loads the clutch friction disks. The support structure 31 includes a first annular disk-like ring member 35 possessing a first ring main body 38 which contacts a portion of the diaphragm spring 30 from the clutch cover 28 side and a seating portion 40 which extends from the first ring main body 38 and seats against the clutch cover 28, a second annular disk-like ring member 36 possessing a second ring main body which contacts the diaphragm spring 30 on the side opposite the first annular disk-like ring member 35, and bolts 37 for fixing the first and second annular disk-like annular disk-like ring members 35 and 36 to the clutch cover 28. One purpose of the invention is to suppress clutch cover wear caused by annular disk-like annular disk-like wire ring members. A hub flange 6 having a boss 11 and a flange 12 extending from the boss 11 to the outer periphery where a drum-shaped element 13 is formed that extends axially to opposite sides of the outer periphery of the flange 12. Plural annular drive plates 7 and plural annular driven plates 8 are disposed between a flywheel and the clutch cover 28. In the flange 12 passage openings 14 are formed which provide air flow. In the two axially projecting portions of the second drum-shaped element 13, there are formed air passage holes 19 and 20, the openings and holes preventing the temperature in friction disks in a dry multi-disk clutch from rising excessively.
