The high-performance chain wheel assembly comprises a chain wheel body, an anti-disengaging plate is arranged on the outer side of the chain wheel body, the anti-disengaging plate is fixedly connected with a bicycle frame, a one-way bearing is arranged on the inner side of the chain wheel body, and the chain wheel body is rotationally connected with the anti-disengaging plate through the one-way bearing. The one-way bearing comprises an outer rotating ring and an inner connecting ring installed on the inner side of the outer rotating ring, a limiting block is integrally formed on the outer side of the inner connecting ring, a sliding column is arranged on one side of the limiting block, and a spring is arranged in the limiting block; by means of the designed one-way bearing and the anti-falling plate, falling of the chain is reduced through blocking and limiting of the anti-falling plate in the using process, the one-way bearing can only rotate in one direction through cooperation of a limiting block, a limiting rolling shaft and a sliding column of the one-way bearing, and therefore a bicycle can walk conveniently; compared with elastic sheet pushing, the pushing is more stable, and the problem that the elastic sheet is easy to damage is avoided.

    本发明公开了一种后轮防脱离变速山地自行车的高性能链轮组件,包括链轮主体,所述链轮主体的外侧设置有防脱板,所述防脱板与自行车架固定连接,所述链轮主体的内侧设置有单向轴承,所述链轮主体通过单向轴承与防脱板转动连接,所述单向轴承包括外转动环和安装在外转动环内侧的内连接环,所述内连接环的外侧一体成型有限位块,所述限位块的一侧设置有滑动柱,所述限位块的内部设置有弹簧;通过设计的单向轴承和防脱板,在使用时通过防脱板的阻挡限位减少链条脱落,且通过单向轴承的限位块、限位滚轴和滑动柱的配合,使单向轴承只能单向转动,从而方便自行车行走,相对于采用弹片推动更加稳定且避免出现弹片容易损坏的问题。
