The invention discloses a bicycle labor-saving driving mechanism. The driving disc is connected to a shaft neck of the rotating shaft, and the two pedals are connected to a left shaft head and a right shaft head of the rotating shaft respectively. And two small gear rings which are symmetrical front and back and two large gear rings which are symmetrical up and down are respectively arranged on the driving disc. A front gear and a rear gear are connected to a shaft head at the front end of the transmission shaft, the front gear and the rear gear are meshed with a small gear ring and a large gear ring on the driving disc respectively, and a rear shaft head of the transmission shaft is connected with a wheel shaft of the rear wheel through a universal coupling. When the large gear ring is meshed with the rear gear, the small gear ring is automatically disengaged from the front gear, and at the moment, the rotating driving disc can conventionally drive the bicycle through the large gear ring, the rear gear and the transmission shaft. The driving disc continues to be rotated, when the small gear ring is meshed with the front gear, the large gear ring is automatically disengaged from the rear gear, and at the moment, the rotating driving disc can drive the bicycle in a labor-saving mode through the small gear ring, the front gear and the transmission shaft.

    一种自行车省力驱动机构。驱动盘连接在转轴的轴颈上,两个脚蹬分别连接在转轴的左右轴头上。在驱动盘上分别设置有前后对称的两个小齿环和上下对称的两个大齿环。在传动轴的前端轴头上连接有前齿轮和后齿轮,前齿轮和后齿轮分别与驱动盘上的小齿环和大齿环啮合,传动轴的后轴头与后车轮的轮轴通过万向联轴器连接。当大齿环与后齿轮啮合时,小齿环将与前齿轮自动脱离啮合,此时转动的驱动盘即可通过大齿环、后齿轮和传动轴对自行车进行常规的驱动。继续转动驱动盘,当小齿环与前齿轮啮合时,大齿环将与后齿轮自动脱离啮合,此时转动的驱动盘即可通过小齿环、前齿轮和传动轴对自行车进行省力的驱动。
