Embodiment 1
[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a bicycle transmission system includes a pedal assembly 1 and a rear wheel 2, the rear wheel 2 is provided with a rear wheel shaft 3, the rear wheel shaft 3 is provided with a driving wheel 4, and the rear wheel 2 is provided with a The driven wheel 5 is provided with an elastic member 6 between the rear wheel 2 and the driven wheel 5, and the elastic member is used to apply force to the driven wheel 5 so that the driven wheel 5 is always in contact with the driving wheel 4, and the driving wheel 4 is provided with a sprocket 43. The sprocket 43 is connected to the step assembly 1 through a chain transmission, and the sprocket 43 is provided with a baffle 44 to prevent the chain from falling off.
[0026] look first figure 2 , the driving wheel 41 facing the driven wheel 5 side is provided with a driving tooth 42, and the driven wheel 5 is provided with a passive tooth 52 meshing with the driving tooth 4...
Embodiment 2
[0032] A bicycle transmission system as described in Embodiment 1, this embodiment has the following differences: Figure 5 As shown, the positioning column 7 is arranged on the rear wheel 2, and the positioning hole 8 is arranged on the driven wheel 5, so that the spring can always ensure that the driven wheel is exerted elastic force, which can reduce the damage of the spring and improve the service life of the spring.
[0033] A bicycle, comprising a vehicle frame, on which the above-mentioned transmission system is arranged, which improves the transmission mode in which the existing chain directly drives the rear wheel, enables the overall vehicle frame to have good transmission stability, high transmission efficiency, and the transmission system is not easy to be damaged , can reduce the misoperation of the rear wheel and improve the safety of driving.
[0034] When in use, the transmission system is installed on the frame of the bicycle, and the driving wheel 4 is driven...
