Front-wheel-driven steering bicycle

Abstract

The invention relates to a front-wheel-driven steering bicycle. A front fork standpipe of the bicycle is sleeved with a universal gear ring, the universal gear ring can rotate by taking the front fork standpipe as an axis, a bicycle frame is provided with a fixed gear wheel, the fixed gear wheel and the universal gear ring are engaged and connected with pedals, a front fork is provided with a steering gear wheel, and the steering gear wheel and the universal gear ring are engaged and connected with a flywheel of a front axle through a chain. During running of the bicycle, the pedals drive the universal gear ring to rotate via the fixed gear wheel, and the universal gear ring drives the steering gear wheel to rotate and then drives a front wheel to rotate through the chain; during steering of the bicycle, the steering gear wheel rotates around the universal gear ring and keeps in contact with the universal gear all the time when simultaneously steering with the front fork, so that the purposes of steering and driving are fulfilled. By the front-wheel-driven steering bicycle, the problem during running the bicycle through forwards flexing both feet is solved, and a fundamental change of lowering the height of the bicycle can be realized to make on / off more convenient and riding safer.

Description

technical field [0001] The invention belongs to the field of bicycles and motor-assisted bicycles. Background technique [0002] The driving mode of existing bicycle all is that both feet are pedaled hard downwards, in order to facilitate the straightening of both feet, the position of the seat is generally all higher, therefore, there is inconvenience for the cyclist to get on and off, and the The high center of gravity leads to unstable driving and easy falls. If adopt the pedaling mode that both feet stretch forward, just can reduce the height of vehicle seat, solve above-mentioned deficiency, and this problem has not been effectively solved. At present, there are mainly the following types of front drive methods for bicycles: one is that the pedal plate is close to the front wheel, and the rear wheel is driven by a chain, which has the disadvantages of too long chain and low transmission efficiency; the second is to directly drive the front wheel, The rear wheel steeri...

Problems solved by technology

[0002] The driving mode of existing bicycle all is that both feet are pedaled hard downwards, in order to facilitate the straightening of both feet, the position of the seat is generally all higher, therefore, there is inconvenience for the cyclist to get on and off, and the The high center of gravity leads to unstable driving and easy falls

If the pedaling method with both feet stretched forward is adopted, the height of the seat can be reduced to solve the above-mentioned deficiencies, but this problem has not been effectively solved

At present, there are mainly the following types of front drive methods for bicycles: one is that the pedal plate is close to the front wheel, and the rear wheel is driven by a chain, which has the disadvantages of too long chain and low transmission efficiency; the second is to directly drive the front wheel, The rear wheel steering structure has the disadvantage of not conforming to people's riding habits; the third is the structure in which the feet directly drive the front axle, which has the disadvantage that the feet hinder the front wheel steering; the fourth is that the pedal plate uses a universal The joint-driven structure of the front wheels has the disadvantage that the front wheels are not stable and the steering is not flexible due to the uneven speed of the universal joint.
