Disclosed is a double-connecting-rod gear transmission mechanism of a bicycle. As shown in the figure 5 of the specification, the double-connecting-rod gear transmission mechanism is composed of a pedal rotating large gear, two front-rear end transmission pinions, two transmission connecting rods, two front-rear end transmission discs and a one-way movable flywheel, and power is sequentially transmitted from pedals to pedal rods, the large gear, the front end pinion, the transmission discs, the transmission connecting rods, the rear end pinion, the transmission discs and the one-way movable flywheel. And finally, the power is transmitted to a rear hub in threaded connection with the inner ring of the one-way movable flywheel to drive a rear wheel to rotate. Meanwhile, in order to prevent the two transmission connecting rods from misplacing and reversing in the power transmission rotating process, the two transmission connecting rods are installed in a mode of a 90-degree included angle of parallel rotation on respectively connected front-end pinion and the rear-end pinion and the front-rear end transmission discs, and the parallel rotating radiuses are the same and the two transmission connecting rods are symmetrically distributed on two sides of the transmission side of the bicycle frame. Therefore, balanced power transmission is achieved, and the phenomenon that the transmission connecting rod misplaces and reverses possibly in the rotating process is prevented.

    自行车双连杆齿轮传动机构。参见说明书附图5,双连杆齿轮传动机构是由脚蹬转动大齿轮、2个前后端传动小齿轮、2根传动连杆、2个前后端传动盘和单向活飞轮组成,动力依次由脚蹬向脚蹬杆、大齿轮、前端小齿轮和传动盘、传动连杆、后端小齿轮和传动盘、单向活飞轮传递,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2根传动连杆在动力传递转动过程中发生错位反转,2根传动连杆在各自连接的前后端小齿轮与前后端传动盘上的平行转动夹角相差90度安装,平行转动半径相同并且对称分布于自行车车架传动侧两边,以此来达到动力均衡传递以及防止传动连杆在转动过程中可能发生的错位反转现象。
