Abstract

The invention discloses a transmission shaft and gearbox integrated transmission structure. The transmission shaft and gearbox integrated transmission structure comprises a main transmission shaft, an auxiliary transmission shaft and a speed change mechanism; the rear end of the main transmission shaft is in transmission connection with a first helical gear, and the front end of the auxiliary transmission shaft is sequentially provided with a second helical gear, a third helical gear and an elastic restoring mechanism; and the speed change mechanism comprises a speed change transmission shaft, a fourth helical gear, a fifth helical gear and a sixth helical gear, wherein the first helical gear is meshed with the fourth helical gear all the time to form a first gear pair to push a sliding block and ejector rod structure, the second helical gear is meshed with the fifth helical gear to form a second gear pair to push the sliding block and ejector rod structure continuously, and the third helical gear is meshed with the sixth helical gear form a third gear pair. According to the transmission shaft and gearbox integrated transmission structure, the transmission shafts of a bicycle are provided with the speed change mechanism additionally, the first gear pair is meshed all the time, namely with the first gear as a normal state, a sliding block and an ejector rod are pushed, the second gear pair or the third gear pair is meshed so that the transmission shaft can be put into the second gear or the third gear, and gear shifting is simple.

Description

technical field [0001] The invention relates to an integrated transmission structure of a transmission shaft and a gearbox, belonging to the technical field of bicycle transmission. Background technique [0002] Bicycles are the preferred means of transportation for green travel. Shaft-driven bicycles have the advantages of long service life, maintenance-free, clean and tidy, and high strength. However, shaft-driven bicycles have the important defect of a single transmission gear ratio and do not have a shifting function. Some bicycle transmission shafts with variable speed function have a very complicated structure, are very cumbersome to manufacture, and do not have popularization. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, and provide an integral transmission structure of a transmission shaft and a gearbox, which has a three-speed shifting function and is easy to shift...
