一种只能星轮主动的滚柱式超越离合器

A Roller Overrunning Outch only Driven by Spider

一种带拨爪滚柱式超越离合器,主要由外环、星轮、滚柱、拨爪环和环叉组成,在环叉和拨爪环对滚柱的约束下,离合器自动实现只能星轮主动的功能。若外环主动时,离合器不会接合,星轮不随外环运动。文中以人力三轮车驱动机构为例说明了这种离合器的用途。

A roller overrunning clutch with pusher dog mainly consists of outer ring, spider, roller, pusher dog ring and fork. In constraint of the fork and the pusher dog ring to the rollers, the clutch achieves the only spider driving function automatically. If the outer ring drives, the clutch won't joint and the spider won't move along with the outer ring. The usage of this kind of clutch is explained with the example of the manpower tricycles driving mechanism.
