Title
(EN) CENTRIFUGAL CLUTCH
(ZH) 离心离合器
Abstract
(EN) Provided is a centrifugal clutch that is capable of either reducing an assist thrust or holding an assist thrust constant even when a clutch shoe is worn down. This centrifugal clutch 200 is providedwith a drive plate 210 that is rotary-driven by a driving force of an engine. The drive plate 210 is provided with pivot support pins 214 and plate-side cam bodies 218. The pivot support pins 214 eachpivotably support a clutch weight 230 by being fitted in an oblong-shaped pin slide hole 231 formed in the clutch weight 230. The plate-side cam bodies 218 are each formed of a cylindrical roller andare in contact with a weight-side cam body 235 of the clutch weight 230. The weight-side cam body 235 is formed to have a curved surface that results in the same cam angle, before and after wear of aclutch shoe 233 proceeds, when the clutch shoe 233 comes into contact with a cylindrical surface of an outer clutch sleeve 240.
(ZH) 本发明提供一种离心离合器,即使离合器蹄块磨耗也能够维持固定的辅助推力或使辅助推力降低。离心离合器200具备通过引擎驱动力旋转驱动的驱动板210。驱动板210分别具备摆动支撑销214及板侧凸轮体218。摆动支撑销214是嵌合于形成在离合器配重230上的长孔状销滑动孔231而将离合器配重230支撑为摆动自如。板侧凸轮体218是由圆筒状的辊筒所构成,并与离合器配重230的配重侧凸轮体235接触。配重侧凸轮体235是形成为,离合器蹄块233的磨耗进行前后中,离合器蹄块233接触到离合器外壳240的圆筒面时的凸轮角度会相同的曲面。
