The invention provides a bicycle gear rocker transmission mechanism. As shown in the figure 3 of the specification, the gear rocker transmission mechanism is composed of a transmission rocker, a speedincreasing large gears, forward and reverse rotation small gears and a one-way movable flywheel; power is sequentially transmitted to a pedal rotation short connecting rod, the transmission rocker, aspeed increasing gear set, the one-way movable flywheel and a rear hub to rotate through a pedal. The designed rotating radius of the pedal rotating short connecting rod is the same as the revolutionradius of a large gear rotating pin, then power is transmitted to the one-way movable flywheel to rotate through a speed increasing large and small gear set, and finally the power is transmitted to the rear hub in threaded connection with the inner ring of the one-way movable flywheel to drive the rear wheel to rotate. Meanwhile, in order to prevent the transmission rocker from misplacing and reversing in the power transmission rotating process, two same-direction rotating speed increasing large gears of which the pin revolution radius is the same as that of a pedal rotating short connectingrod are designed and mounted at the tail part of the transmission rocker and are symmetrically distributed on two sides of the reverse rotation small gear, so that balanced power transmission is achieved, and the phenomenon that the transmission rocker misplaces and reverses possibly in the rotating process is prevented.

    自行车齿轮摇杆传动机构。参见说明书附图3,齿轮摇杆传动机构是由传动摇杆、增速大齿轮、正反转小齿轮和单向活飞轮组成,动力由脚蹬依次向脚蹬转动短连杆、传动摇杆、增速齿轮组、单向活飞轮和后轮毂传递转动,脚蹬转动短连杆设计旋转半径和大齿轮转动销钉公转半径相同,再通过增速大小齿轮组将动力传递给单向活飞轮转动,最后将动力传递给与单向活飞轮内圈螺纹连接的后轮毂来带动后轮转动。同时为了防止传动摇杆在动力传递转动过程中发生错位反转,在传动摇杆尾部设计安装了2只销钉公转半径与脚蹬转动短连杆相同的同向转动增速大齿轮,对称分布于反转小齿轮两侧,以此来达到动力均衡传递以及防止传动摇杆在转动过程中可能发生的错位反转现象。
