Compound drive bicycle

Abstract

The invention discloses a compound drive bicycle. The bicycle comprises a transmission hoist in transmission connection with a corresponding intermediate shaft wheel and a pneumatic drive device in transmission connection with a rear wheel and further comprises a transmission conversion device. The transmission conversion device comprises air cylinders and a crank. The air cylinders are in transmission connection with the transmission hoist through the corresponding crank and a transmission coupling device. The air cylinders are connected with the pneumatic drive device through exhaust valvesof the air cylinders. The compound drive bicycle is particularly simple and reasonable in transmission structure, fast in starting, high in traveling speed and transmission efficiency, capable of saving more labor, good in different-power coordination and balanced in drive force in the traveling process.

Description

technical field [0001] The invention relates to a bicycle, in particular to a compound drive bicycle. Background technique [0002] None of the driving or transmission mechanisms of existing independent bicycles are pure gear chain transmission structures, and the rear wheel drives the flywheel structure with a single chain and a single gear. The driving method is traditional, and the transmission balance and uniformity of the driving force are limited. Possibility of improvement; and the self-powered bicycle starting performance of existing this type of transmission structure also needs to be improved. And the bicycle of the belt auxiliary drive that releases afterwards has certain irrationality because there is certain irrationality in aspects such as structure as the bicycle that has drive hoist, and it is not enough to the above-mentioned defect and deficiency improvement of existence, and effect is not good. In recent years, some dual-drive bicycles that have been rele...

Problems solved by technology

[0002] None of the driving or transmission mechanisms of existing independent bicycles are pure gear chain transmission structures, and the rear wheel drives the flywheel structure with a single chain and a single gear. The driving method is traditional, and the transmission balance and uniformity of the driving force are limited. Possibility of improvement; and the self-powered bicycle start-up performance of existing this type of transmission structure also needs to be improved

And the bicycle with the auxiliary drive that releases later has certain unreasonableness because there is certain irrationality in aspect such as structure as the bicycle with transmission hoist, and it is not enough to the above-mentioned defect and deficiency improvement of existence, and effect is not good

In recent years, some dual-drive bicycles have been introduced in response to this, because the relative structure is relatively complicated, such as the structure of the relevant pneumatic drive system is not reasonable, so that its failure rate and transmission efficiency are affected to a certain extent

Its applicability needs to be improved
