Front Wheel Drive Rear Wheel Steering Folding Bicycle

Abstract

The invention provides a folding bicycle with a front wheel for driving and a rear wheel for steering. The folding bicycle comprises the front wheel, the rear wheel, a pedal assembly, a handlebar assembly, a seat cushion assembly and a bicycle beam. The front wheel is installed on the front portion of the bicycle beam, the pedal assembly is installed on the bicycle beam, the seat cushion assembly is installed on the rear portion of the bicycle beam, a wheel frame matched with the bicycle beam in a rotating mode is installed on the rear portion of the bicycle beam, the rear wheel is installed on the wheel frame, the handlebar assembly is provided with a hollow shaft and a handlebar rod, the hollow shaft is installed on the bicycle beam, a hoop is installed on the upper portion of the hollow shaft, the wheel frame is formed by integrally connecting a rotation shaft and a support, the rotation shaft is installed on the bicycle beam, a steering mechanism is provided with a driving gear and a driven gear, the driving gear and the driven gear are meshed with each other, the driving gear is installed on the hollow shaft, and the driven gear is installed on the rotation shaft. A transmission mechanism is connected between a rotation shaft of the pedal assembly and an axle of the front wheel. According to the folding bicycle, the front wheel is used for driving, the rear wheel is used for steering, and therefore the whole bicycle is more compact and more reasonable in layout while guaranteeing that the bicycle meets the requirements of human physiological function sizes during riding; the foldable parts of the bicycle are selected reasonably, and therefore complexity caused by folding and unfolding of the bicycle is avoided.

Description

technical field [0001] The invention relates to a bicycle, in particular to a folding bicycle with front-wheel drive and rear-wheel steering. Background technique [0002] Existing bicycles can be divided into two categories: non-folding bicycles and folding bicycles according to whether they can be folded. Non-folding bicycles usually meet the normal requirements of human physiological function size when riding, but the overall size is large and heavy. Existing folding bicycles , it has the advantages of small size and light weight after being folded, but the following disadvantages will exist if the degree is low: the diameter of the wheel is small, and the bumps are severe when riding; it is difficult to meet the size requirements of human physiological functions, and the comfort when riding Good; too many folding points lead to more cumbersome folding and opening; the increase of material at the folding place results in an increase in local weight. In addition, most of ...

[0002] Existing bicycles can be divided into two categories: non-folding bicycles and folding bicycles according to whether they can be folded. Non-folding bicycles usually meet the normal requirements of human physiological function size when riding, but the overall size is large and heavy. Existing folding bicycles , it has the advantages of small size and light weight after being folded, but the following disadvantages will exist if the degree is low: the diameter of the wheel is small, and the bumps are severe when riding; Good; too many folding points lead to more cumbersome folding and opening; the increase of material at the folding place results in an increase in local weight

In addition, most of the existing types of bicycles are rear-wheel drive, which also makes it difficult to achieve both folding and human physiological functions.
