FRICTION CLUTCH HAVING MULTI FRICTION PLATES, CLUTCH HOUSING, METHOD OF MANUFACTURING THE CLUTCH HOUSING AND SYSTEM FOR THE FRICTION CLUTCH HAVING MULTI FRICTION PLATES

摘要

A multi-friction clutch comprises a clutch housing adapted to receive the power from the first rotary shaft and rotate, the clutch housing having a plurality of guide grooves axially formed on a circumferential side wall thereof; a plurality of first frictional plates each having a plurality of guide pieces formed outwardly from an outer circumferential surface thereof; a plurality of second frictional plates arranged alternately between the plurality of first frictional plates; a rotary hub engaged with the second frictional plates to rotate along with the second frictional plates and adapted to transmit the power to the second rotary shaft; a fixing ring mounted on the top circumferential edge of the clutch housing to surround the top circumferential edge of the clutch housing, the fixing ring having a plurality of retaining pieces formed to be bent protrudingly inwardly from the top circumferential edge thereof; and a fixing member snap-fit into an inner circumferential surface of an upper end portion of each of equally spaced apart circumferential side walls of the clutch housing for preventing escape of the fixing ring from the clutch housing.
