JUDDER PREVENTING DEVICE IN CENTRIFUGAL CLUTCH

摘要

PURPOSE:To inhibit movement of inner clutch parts for preventing a centrifugal clutch from juddering by urging a friction plate against one lateral surface of the inner clutch parts thereof through a Bellerville spring. CONSTITUTION:Inner clutch parts 3 which can tilt outward overcoming a spring 5, are attached to a plate member 2 fixed to a drive shaft 1. The inner clutch parts 3 are frictionally engaged with an outer clutch part 6 for transmitting power when centrifugal force is produced. In this state, the inner clutch parts 3 is inhibited from moving, since a friction plate 8 is urged against one lateral surface of the inner clutch parts 3 by a Bellerville spring 8, thereby the quick return of the inner clutch parts 3 just after the inner clutch parts 3 are tilted outward at a high acceleration, that is, ''judder'', may be prevented.
