The invention discloses a bicycle parallel transmission connecting rod mechanism. According to the Figure 3 in the specification, the parallel transmission connecting rod mechanism is a whole set of low-cost transmission mechanism composed of a parallelogram four-connecting-rod transmission mechanism and a simple speed-increasing planetary gear set; power is sequentially transmitted to a set of parallel transmission connecting rod mechanism composed of a pedal rotating short connecting rod, a parallel transmission long connecting rod and a one-way movable flywheel through pedals and generatesrotation; the designed rotating radius of the pedal rotating short connecting rod is the same as the rotating radius of the one-way movable flywheel pin; then the power is transmitted to the speed-increasing planetary gear set through the one-way movable flywheel to rotate; and finally, the power is transmitted to a spline rear axle matched with the speed-increasing planetary gear set to drive a rear hub connected with the spline rear axle to rotate, so that the purpose of power transmission is achieved. Meanwhile, in order to prevent the parallel transmission long connecting rod from being dislocated and rotating reversely in the parallel rotating process of the parallelogram four-connecting-rod transmission mechanism, a short connecting rod for preventing reverse rotation caused by dislocation is arranged between the middle size position of the parallel transmission long connecting rod and the frame, and the rotating radius is the same as that of the pedal rotating short connecting rod, so that the parallel transmission long connecting rod is prevented from misplacing and reversing in the rotating process, and the pedal rotating short connecting rod and the one-way movable flywheel pin are forced to achieve the purpose of synchronously rotating in the same direction to output power.

    自行车平行传动连杆机构。参见说明书附图3,平行传动连杆机构是由一套平行四边形的四连杆传动机构和简易增速行星齿轮组组成的一整套低成本传动机构,动力由脚蹬依次向脚蹬转动短连杆、平行传动长连杆和单向活飞轮组成的一套平行传动连杆机构传递并产生转动,脚蹬转动短连杆设计旋转半径和单向活飞轮销钉旋转半径相同,再通过单向活飞轮将动力传递给增速行星齿轮组转动,最后将动力传递给与增速行星齿轮组匹配的花键后车轴,带动与之相连的后轮毂转动,以此来达到动力传递的目的。同时为了防止平行传动长连杆在平行四边形四连杆传动机构平行转动过程中发生错位反转现象,在平行传动长连杆中间尺寸位置和车架之间再安装了一个防止错位反向转动短连杆,旋转半径与脚蹬转动短连杆相同,以此来防止平行传动长连杆在转动过程中发生错位反转,迫使脚蹬转动短连杆和单向活飞轮销钉之间达到同步同向转动输出动力的目的。
