Patent number: 8025138Abstract: A multi-plate clutch system includes an outer clutch member having a plurality of first clutch plates thereon, a central spool having a plurality of second clutch plates thereon interspaced with the first clutch plates. The clutch system also includes a cam mechanism including a protruding cam and a recessed cam. The protruding cam and the recessed cam respectively include first inclined faces and second inclined faces, which are inclined in the same direction with respect to the circumferential direction. The protruding cam is thus brought into a point contact with the recessed cam during clutch engagement. As such, the multi-plate clutch system can maintain constant variable characteristics of the clutch capacity even when there is a variation in processing accuracy at the time of the production.Type: GrantFiled: October 16, 2007Date of Patent: September 27, 2011Assignee: Honda Motor Co., Ltd.Inventors: Kei Yoshinaga, Isamu Takahashi, Toshiharu Akutsu, Kazumitsu Yamamoto, Yoshiki Nagahashi
