Bicycle with pressure speed-aid device

Abstract

The invention relates to the technical field of a bicycle, in particular to a bicycle with a pressure speed-aid device. The bicycle provided by the invention comprises a bicycle body and the pressure speed-aid device, wherein the pressure speed-aid device comprises a liquid-gas tank, a plunger pump, a supercharger, an energy accumulator and a liquid-gas motor which are successively connected; theplunger pump is connected with pedals; the liquid-gas motor is connected with the driving shaft of a rear wheel; a driving device for driving the supercharger is arranged between the plunger pump andthe supercharger; a check valve is arranged between the supercharger and the energy accumulator; and a pressure regulating device is arranged between the energy accumulator and the liquid-gas motor. When a rider treads the pedals, the mechanical energy supplied to the plunger pump through the pedals is converted into the pressure potential energy of liquid / gas, thereby realizing the superchargingfor the first time; then, the supercharged liquid / gas is supercharged for the second time through the supercharger, and the liquid / gas is accumulated through the energy accumulator; the liquid / gas issupercharged for two times, thereby effectively enhancing the pressure difference between the pressure of the liquid / gas and the normal pressure; and the supercharging effect and energy conversion effect are good, and the driving force of the bicycle is strengthened.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle with a pressure booster. Background technique [0002] With the progress of society, people have higher and higher demands on the quality of basic life such as "clothing", "food", "housing" and "travel". In terms of "travel", bicycles are currently the most expensive means of transportation. It is cheap and widely popular. Because the bicycle body is light and does not need to be refueled, it is very convenient to ride. It can not only reduce air pollution and noise, but also achieve the effect of health and leisure, which is in line with the modern people's pursuit of environmental protection and low-carbon life. condition. [0003] At present, traditional chain bicycles are generally used in the domestic bicycle market, although they can play the role of bicycles for transportation. However, traditional bicycles mainly rely on the immediate output of manpower to dr...

Problems solved by technology

Because in the prior art, the pressure potential energy of the hydraulic oil is generally only increased by a first-stage booster device such as a plunger type oil pump, the oil suction pressure of the first-stage booster device is usually only 0.02-0.05Mpa, and there is no step difference during the booster process, so The supercharging effect is not ideal, the energy conversion effect is poor, and the driving effect provided for the bicycle to move forward is poor
