The invention discloses a rear fork chain guide. A bicycle chain guide relates to the technical field of bicycle chain guides and is arranged on a bicycle frame, a flywheel, a rear fork and a fluted disc are arranged on the bicycle frame, the rear fork is arranged between the flywheel and the fluted disc, the flywheel and the fluted disc are rotatably arranged at the two ends of the rear fork respectively, the flywheel and the fluted disc are sleeved with a chain, a rear transmission is arranged on the side, close to the flywheel, of the rear fork, and a chain hooking device is arranged on the rear transmission. A chain sequentially passes through the fluted disc, the chain hooking device, the rear transmission and the flywheel, the chain guiding device comprises a chain guiding device body, the chain guiding device body is arranged on the side, away from the flywheel, of the rear fork and comprises a supporting part, a guiding seat and a connecting part, the guiding seat is arranged at one end of the supporting part, the chain is guided through the guiding seat, and the connecting part is arranged at the other end of the supporting part and connected with the supporting part. And a fixing hole is formed in the connecting part. By arranging the chain guide body, a chain can be guided, and friction loss caused by collision between the chain and a rear fork is avoided.

    本发明公开了一种后叉导链器。涉及自行车导链器技术领域,设置在车架上,车架上设有飞轮、后叉和齿盘,后叉设置在飞轮和齿盘之间,飞轮和齿盘分别可转动的设置在后叉的两端,飞轮和齿盘上套设有链条,后叉靠近飞轮的一侧设有后变速器,后变速器上设有勾链器,链条依次通过齿盘、勾链器、后变速器和飞轮,包括:导链器本体,导链器本体设置在后叉远离飞轮的一侧,导链器本体包括支撑部、引导座和联结部,引导座设置在支撑部的一端,通过引导座对链条进行导向,联结部设置在支撑部的另一端,联结部上设有固定孔。本发明通过设置导链器本体,能够对链条进行导向,避免链条与后叉碰撞产生摩擦损耗。
