Description

The boosted vehicle of compressed air-driven

Technical field

The utility model relates to a kind of boosted vehicle, especially a kind of mini-motorcycle of compressed air-driven.

Background technology

At present, boosted vehicle mainly is that the electric power with rechargeable battery is that energy drives rickshaw and advances, and the shortcoming of its existence is: 1. the rechargeable battery that boosted vehicle adopted needs constantly charging, work complicated, bother; 2. need consume a large amount of electric energy when charging, and energy consumption is higher; 3. the rechargeable battery life-span is shorter; 4. the function unit of boosted vehicle is more, easily et out of order; 5. the rechargeable battery of scrapping causes environmental pollution easily.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple and reasonable, efficient is higher, adopts the boosted vehicle of compressed air-driven.

The purpose of this utility model is achieved in that

A kind of boosted vehicle of compressed air-driven, comprise vehicle frame, wheel, wheel comprises tire, rim, axletree, it is characterized in that: on cycle frame, be fixed with a compressed air reservoir, the axial of the axletree of bicycle divided flow nozzle for the cavity structure and at its uniform air that is connected with cavity that is shaped on that directly makes progress, both sides at axletree are fixed with pair of bearings with rotational symmetry, the outer ring of this bearing all is fixed with a rim supporting disk, this supporting disk installs mutually with rim, the uniform blade that is fixed with of rim inner edge in supporting disk, compressed air reservoir are communicated with the cavity of axletree by air pipe.

And described air is shunted upper end of nozzle portion and is bending, is 25～75 ° of angles with axial level.

And the blade upper end also is made as bending, and divides the upper end of flow nozzle crooked in opposite directions with air.

And, the uniform breather hole that is communicated with its inner chamber that is shaped on of described rim supporting disk hoop.

And, described axletree in the axial direction all sealing be fixed with seal cover cap, be fixed with a pneumatic fitting that can be connected and be communicated with cavity with the air pipe of compressed air reservoir therein on seal cover cap.

And described compressed air reservoir is to be packed on the crossbeam of vehicle frame.

Advantage of the present utility model and good effect are:

1. the boosted vehicle of the related compressed air-driven of the utility model, it drives used energy is the pressure energy of air, and environmentally safe only must be stored in pressurized air in the accumulator unit and just can realize, thereby avoided when rechargeable battery is scrapped processing, environment damage;

2. the utility model is simple and reasonable, operate steadily and adjustable-speed, and the efficient of riding height, what obtain pressurized air institute power consumption source the required energy will be low when rechargeable battery charges is many, has saved a large amount of energy.

3. the utility model not only can be applicable on the bicycle, also can be applied on other rickshaws such as three-wheel vehicle, the small four-wheel car, and field of application is comparatively extensive.

Fig. 2 is the enlarged diagram (semi-sictional view) of the utility model wheel;

Fig. 3 is that the A-A of Fig. 2 is to cross-sectional view.

The specific embodiment

Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.

The boosted vehicle of this compressed air-driven can be bicycle, three-wheel vehicle or four-wheeled etc., is that example is narrated below with the bicycle, and the type of drive of other rickshaws is basic identical.

A kind of mini-motorcycle of compressed air-driven, its main body comprise vehicle frame 5 and wheel 1, and vehicle frame divides by its forward and backward car fork and installs with the axletree 2 of front and back wheel respectively.Wheel comprises tire 7, rim 8, axletree.

Innovation part of the present utility model is:

1. be fixed with a compressed air reservoir 6 on cycle frame, in the present embodiment, compressed air reservoir is installed on the cross member of frame of bicycle.

2. the structure and the type of drive of cycle wheel have been changed, present embodiment is changed into example (also can change the structure of bicycle rear) with the bicycle front-wheel: axletree is the cavity structure in the axial direction, the uniform air that is connected with cavity that is shaped on that makes progress in the footpath of this axletree divides flow nozzle 11, and present embodiment is provided with four air and divides flow nozzle; This air divides the upper end of flow nozzle to be bending, is 25～75 ° of angles with axial level.The outer, coaxial symmetry is fixed with pair of bearings 10 in the both sides of axletree, all be fixed with a rim supporting disk 13 on the outer ring of this bearing, the lower end of this supporting disk can adopt mode such as tightening screw and outside race installs, its upper end also can install with the rim inner edge by bolt or welding manner etc.The uniform breather hole 12 that can be communicated with its inner chamber that is shaped on of this rim supporting disk hoop on its card.The uniform blade 9 (being 36 blades in the present embodiment) that is fixed with in rim inner edge position in supporting disk, this blade upper end also is made as bending, and divides the upper end of flow nozzle crooked in opposite directions with air, to realize that blade can bear more air kinetic energy.Compressed air reservoir is by control cock 4 dominant discharge, and is packed in the pneumatic fitting 14 that the axletree side seal covers on 15 by air pipe 3 and sealing and is connected, and compressed air reservoir is connected with the cavity of axletree.

Principle of work of the present utility model is:

Before riding, compressed air reservoir is full of high pressure air, when riding, the bicyclist needs when air-assisted, can open the control cock on the airline, make high pressure air enter cavity by pneumatic fitting, and this high pressure air divides the flow nozzle ejection through air, the action of high-speed airflow of formation is on blade, thereby drive wheels is rotated, and bicycle is moved ahead.

Weary gas after the acting is discharged through breather hole, and guaranteeing has enough pressure reduction between operating air pressure and the ambient pressure, with the task performance of performance pressurized air maximum.
