A walking type bicycle

Abstract

The invention relates to a bicycle of the ambulation style. It contains the frame of the bicycle, the braking mechanism, the back annulus for driving, the back-annulus axes, the tyre, the footplate is fixed on the stepping handle, the fan-shaped main gear wheel and the unilateralism flywheel with the gear wheel. The left and right sides of the frame of the bicycle sets up a stepping handle and its footplate, the gear wheel and the unilateralism flywheel. The footplate is fixed in the front of the stepping handle and the gear wheel is fixed in the back of the stepping handle. The handle body between two ends of the stepping handle has the pinhole and the handle pin connects on the frame of the bicycle and hinge-joints on the frame of the bicycle by the pinhole and the handle pin. The outer circle of the unilateralism flywheel is the gear or the chain wheel. The footplate connects on the gear wheel. On the one side of the footplate are set up with the side-hamulus. The invention is easy and applied. It has the deft organization, the high efficiency transmission, the comfortable riding, the quakeproof and the defending bursting-tyre.

Description

【Technical field】 [0001] The present invention relates to a walking bicycle, and more particularly, the present invention relates to a reciprocating pedal bicycle. 【Background technique】 [0002] Bicycles are widely adopted by families and individuals in China because of their economy, convenience, flexibility, pollution-free, and free parking. Although with the improvement of people's lives, mainstream means of transportation and machinery are constantly being upgraded: from bicycles to buses, from buses to motorcycles, and then from motorcycles to private cars... This development trend is in the ascendant, but with it The social, natural, and economic problems such as energy shortage, environmental pollution, and traffic congestion that come with it are also becoming a strong resistance to restricting this development trend. It can be predicted that in the next few decades, no matter in China's urban or rural areas, the vast majority of the population will still use bicyc...

AI Technical Summary

Problems solved by technology

[0004] Bicycle belongs to a kind of simple walking-replacing machine, and through hundreds of years of development, although the technology is very mature and stable, it is difficult to make a major breakthrough in technology, but the bicycles currently available in the market have the following disadvantages: 1) mostly adopt pedal circle The driving mode is equivalent to a person doing long-span running. The exercise is intense, the muscles are highly contracted, the energy consumption is huge, and people are easily fatigued.

2) The pedal handle is short and the effective moment arm is short

3) Due to the circular motion of the pedals, the effective force arm changes cyclically from: zero---maximum---zero---(counting from the pedals being vertical), there will be "dead points" and "blind spots" "Appears, poor continuous exertion, small useful effect

4) poor security and stability

7) It is extremely dangerous when the tire is punctured or leaks during driving

However, due to the special supporting position and structure of the rocker arm, the device must adopt a reset mechanism to help the left and right two fan-shaped active meshing wheels and the rocker arm to realize the alternation of the upper and lower positions, and the reset mechanism is a steel wire sleeve (wire Pull rope), obviously, such a steel wire will be easily worn by the outer casing under frequent and forceful pulling during riding, and the efficiency and practicability of the reset transmission are very low
