Description

Air motor

Technical field

The utility model relates to a kind of power plant, is a kind of air motor that Motor Vehicle drives that is mainly used in specifically.

Background technique

The driving mode of transmission device is many, for example has by motor and diesel engine, petrol engine etc. to drive the general more complicated of these power equipment structures, and cost height as power equipment.

The power equipment that is used for the driving machine motor-car generally is diesel engine, petrol engine, owing to there is above-mentioned problem, for reducing cost better and the needs of environmental protection etc., the power equipment that wind energy, solar energy etc. have occurred, but up to the present, this class technology is still immature, and is subjected to the restriction and the climatic influences of geographical conditions, operating exists many problems, does not therefore also obtain excellent popularization and uses.

According to relevant document record, at present also there are many technician to adopt the air pressure mode, by cylinder and reciprocating cylinder output shaft, cooperating crank mechanism that to-and-fro motion is converted into again rotatablely moves, be used for drive transmission, and use the Motor Vehicle aspect, this indirect driving mode is not applied because of a variety of causes yet.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, cost is low, the air motor that is mainly used in Motor Vehicle of enough power can be provided.

The air motor that the utility model provides comprises the air pressure generating mechanism, thereby can produce the air pressure rotating machinery of the drive output shaft rotation that rotatablely moves by air pressure.

Described air pressure rotating machinery comprises shell and the runner that places in the shell, rotor periphery and housings are formed with toroidal cavity, and the outer weekly interval at runner is equipped with fan blade, on shell, have respectively as the suction port of promotion fan blade rotation and the relief opening that is used as exhaust, described suction port is connected with the steam outlet pipe of air pressure generating mechanism, and described output shaft is installed in the runner center.

The toroidal cavity that the airintake direction of suction port and runner and shell form is tangent.

Described air pressure generating mechanism is an air compressor.

Output shaft connects transmission shaft by the accelerator of being made up of big or small gear through gearbox.

It also is connected to the generator that the kinetic energy that utilizes pto to produce changes into electric energy, and generator is connected to storage battery.

The utility model is owing to produce air pressure by the air pressure generating mechanism, fan blade in the air pressure rotating machinery is exerted pressure, runner in the air pressure rotating machinery is rotated, drive output shaft and rotate generation power, by regulating the diameter of air pressure size and runner, export required power, replaceable existing Motor Vehicle corresponding driving part.The utility model is simple in structure, cost is low, and enough power can be provided, and is used for the driving of Motor Vehicle, thereby reduces cost better and satisfy the needs of environmental protection etc.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the air motor that the utility model provides, it comprises air pressure generating mechanism 1, thereby can produce the air pressure rotating machinery 2 of drive output shaft 3 rotations that rotatablely move by air pressure, and described air pressure generating mechanism 1 is an air compressor.

Described air pressure rotating machinery 2 comprises shell 6 and the runner 7 that places in the shell, runner 7 peripheries and shell 6 the insides are formed with toroidal cavity, and the outer weekly interval at runner 7 is equipped with fan blade 5, form air-pressure chamber between fan blade 5 and the fan blade 5, on shell 1, have respectively as the suction port 4 of promotion fan blade 5 rotations and the relief opening 8 that is used as exhaust, described suction port 4 is connected with the steam outlet pipe of air pressure generating mechanism 1, described output shaft 3 is installed in runner 7 centers, the toroidal cavity that the airintake direction of this suction port 4 and runner 7 and shell 1 form is tangent, so that the air inlet aspect ratio is preferable, fan blade 5 is stressed more satisfactory.

Be preferably in cross section size and the good teamwork of fan blade 5 peripheries size along the toroidal cavity of airintake direction position, in the situation that does not influence fan blade 5 rotations, to reduce friction on the one hand, reduce air leakage phenomena on the other hand as far as possible, the cross section of toroidal cavity can be and add main trend gradually then, because fan blade is so long as stressed near suction port 4 places.The shape of cross section of fan blade 5 and quantity can be decided according to the realization needs.

The aperture position of relief opening 8 is seen Fig. 2.Recovery tube can be installed in relief opening 8 positions, the gas of discharging is recycled.

Pto 3 connects transmission shaft 12 by the accelerator of being made up of big or small gear 13 through gearbox 11, thereby can be used for the driving of Motor Vehicle.Accelerator 13 can improve rotating speed, and gearbox 11 is used for regulation stall and commutation.It also is connected to the generator 10 that the kinetic energy that utilizes output shaft 3 to produce changes into electric energy, and generator 10 is connected to storage battery 9.Storage battery 9 can be air pressure generating mechanism 1 power supply is provided.

The quantity of the air pressure rotating machinery 2 in the utility model can be decided as required, shows it is two among Fig. 5, also can be three, four etc. if desired, and each air pressure rotating machinery 2 can air pressure generating mechanism of corresponding configuration.

Working principle is: after the pressure of air pressure generating mechanism 1 acquires a certain degree, open outlet valve, gas enters air pressure rotating machinery 2 by suction port 4, is subjected to gas pressure, promotes fan blade 5 rotations, output shaft 3 rotations this moment, thereby exportable power.
