The invention discloses a power input device suitable for a bicycle. The power input device comprises a first gear shaft and a second gear shaft which are rotationally connected, a first straight gear and a second straight gear are installed on the surfaces of the first gear shaft and the second gear shaft respectively, a third straight gear meshed with the first straight gear is installed on the surface of a third gear shaft, a fourth straight gear meshed with the second straight gear is mounted on the surface of the fourth gear shaft, and a transmission assembly can enable the rotating directions of the third gear shaft and the fourth gear shaft to be always opposite; and the first output shaft and the second output shaft are fixedly connected, the third gear shaft is rotationally installed on the surface of the first output shaft, the fourth gear shaft is rotationally installed on the surface of the second output shaft, and the third gear shaft and the fourth gear shaft are provided with a first limiting assembly and a second limiting assembly respectively, so that the first output shaft rotates in the same direction all the time. The device is installed on a bicycle, the first output shaft can continuously rotate in the same direction without rotation of the pedal connecting rod during riding, and the transmission efficiency is high.

    本发明公开了一种适用于自行车的动力输入装置,包括转动连接的第一齿轮轴和第二齿轮轴,两者表面分别安装有第一直齿轮和第二直齿轮,第三齿轮轴表面安装有与第一直齿轮相啮合的第三直齿轮,第四齿轮轴表面安装有与第二直齿轮相啮合的第四直齿轮,传动组件能够使第三齿轮轴和第四齿轮轴的转动方向始终相反;第一输出轴和第二输出轴固定连接,第三齿轮轴转动安装于第一输出轴表面,第四齿轮轴转动安装于第二输出轴表面,第三齿轮轴和第四齿轮轴分别设有第一限位组件和第二限位组件,使第一输出轴始终沿同一方向旋转。将本发明安装到自行车上,骑行时不需要踏板连杆旋转度就能使第一输出轴沿相同方向连续不断地旋转,传动效率高。
