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...

Abstract

The invention relates to a bicycle transmission system which comprises a pedal assembly and a back wheel. The back wheel is provided with a rear axle shaft, a driving wheel is connected to the rear axle shaft, a driven wheel is arranged on the back wheel, an elastic piece is arranged between the back wheel and a driven part, a chain wheel is arranged on the driving wheel and is in transmission connection with the pedal assembly through a chain, and a baffle is arranged on the chain wheel. The bicycle transmission system has the beneficial effects that the pedal assembly drives a driving part to rotate, the driving part drives the driven part to rotate, the driven part drives the back wheel to rotate, and therefore an existing transmission manner that the pedal assembly directly drives the back wheel is changed, the travelling safety and stability are improved, damage to the transmission assembly is reduced, the transmission ratio during transmission is improved, and the service life is prolonged. The elastic piece is arranged, and therefore it can be guaranteed that the back wheel applies action force to the driven part, the driven part is in contact with the driving part all the time, the transmission efficiency of the driving part and the driven part is improved, and the stability is good. In addition, the invention provides a bicycle comprising the above transmission system.

Description

technical field [0001] The invention relates to a bicycle transmission system and the bicycle. Background technique [0002] At present, bicycle is a kind of commonly used human means of transportation, and the vehicle frame part is the basic structural body that constitutes bicycle, also is the skeleton and the main body of bicycle, and other parts are also all directly or indirectly installed on the vehicle frame, and the transmission in existing bicycle When the system is working, the transmission belt directly drives the rear wheel to rotate, so that the bicycle keeps moving forward, the transmission efficiency is low, and the transmission components are easily damaged. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bicycle transmission system and the bicycle thereof, so as to solve the problems of easy damage and low transmission efficiency of the existing transmission system. [0004] In order to solve ...
