IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to an electronic throttle valve, and more particularly to controlling the degree of opening of an air passage of a valve body by using a transmission assembly for accurately adjusting the amount of intake air. In turn, an electronic throttle that controls the power of an engine. ', [Prior Art] The f-throttle controller, such as the Republic of China Announcement No. M3〇i2 engine, which is a new patent for the improvement of the nipple flap structure, and = section = side formation - intake port, the intake -2; mouth-end knot'-: the tongue is connected to a turntable, and the shaft is located in the braided-throttle cable connection-oil=turntable::set-torsion spring and the throttle pedal, the throttle p pedal. In this way, #—the driver is not slammed when the driver steps on the 'forming'-off state, the turntable drives the shaft to cooperate:::::, the throttle is reduced to a state of opening, to 楹°" That is to say, the flap of the rolling door opens j, and then with C:: solar terms - only the throttle controller is used, which is less able to mechanically drive the conventional throttle and the second power, so it fails. To achieve the improvement of the other conventional throttle control cry, Lord, II. In view of this, there is a motor driving the shaft to rotate, and the main one is by a DC motor or a servo cymbal, so it is generally used today. The response speed of the servo motor is higher than that of the "IL motor driving the throttle valve 1328074 · month opening and closing. Moreover, the DC motor still has to be configured to - the system is decelerated by the number of gears having a number of gears. Thereby, when the driver steps out the ^^ to transmit the signal to the DC motor by the transmission controller, the DC motor and the speed reducer can be used to drive the slave control degree. In general, the above-mentioned DC motor is used as a conventional throttle controller, which can be used to adjust the driving speed to improve the performance of the bow and the fuel consumption and the amount of milk. The two-valve control certificate is also only applicable to the technical field of automobiles. The throttle control of the more advanced cars on the market is used to cry: the application of the cockroaches, the air system and the fuel consumption have gradually become more and more pre-service, such as locomotives. Electronic drive see 'However, if you want to drive, but the layer 吝 h nipple controller applied to the machine p is easy to produce the following problems, for example. The configured deceleration _ by the number of 5 hp "motor volume weight It is also composed of uf 乂 ^ ^ wheel, so the speed reducer directly increases and occupies a considerable space, and is not suitable for the mouth-to-mouth transmission. The S-machine is easy to produce the material velocity by the gears of several gear ratios (4). In the process, the backlash of each wheel is opposite to each other. Furthermore, the image is affected by the normal operation of the throttle controller, and the valve is usually equipped with a torsion spring to avoid the throttle. Go / piece to gas The flow disturbance affects the accuracy of the intake air volume control. When the electric motor is controlled, it is necessary to pass a large amount of sufficient torque to drive the opening of the flap, so the 7 — ..., -427 The power consumption has also increased significantly, which really makes the DC motor easy to be caused by =: and _. Also, when it is desired to make the throttle above the easy-to-break system, it is also due to the button and the 贝 贝 贝 贝The position control method achieves power saving; the DC motor performs power-off operation, and there is no known solar throttle. For the above reasons, it is necessary to further improve the upper controller. 〃 n' can be applied to the throttle point of a general locomotive. :口: :Invented and improved the above-mentioned conventional throttle controller, the lack of transmission, the I-moving component, the volute and the worm wheel, are used to replace the structure of the conventional reducer, so as to control a throttle valve. The intake air amount of the air passage can therefore be relatively reduced by the throttle controller 2 == an effect' and can be applied to - [Summary of the invention] An electronic throttle is provided by the main purpose of the electronic = month, which is a borrowing type Completion brake force unit drive A worm and a worm gear are matched to each other to interlock with each other - the w-opening and closing action of the squirrel-like body is known to be 5 weeks, that is, the amount of intake air, so that the invention has the effect of improving the engine transporting the month b and reducing the fuel consumption. Use:: The purpose of the Ming is to provide a kind of electronic throttle, which is a simple transmission button for the profit and exhaust gear, so as to reduce the section relatively, and the power unit does not need to supply torque. Positioning (4), the invention has the function of not occupying space, power and anti-nuclear power unit overheating. The electronic throttle according to the invention comprises a - throttle π body, an 8-position seat and a transmission component. The throttle body Providing - an air passage, and a control panel for opening and closing the air passage; the positioning seat is coupled to the ▲ side of the throttle valve, the transmission assembly is provided with a worm, a worm gear and a power early 1 and a spur gear Mutual anger and can be turned off.

By this, ^ can reach the throttle body precisely! The amount of money, the function of the hand movement and the reduction of fuel consumption. Λ As mentioned above, compared with the conventional throttle controller, the power consumption is high and it is easy to occupy a considerable space, and it has disadvantages such as being unsuitable for direct mounting on the locomotive. According to the present invention, the rotation 31 and the _ wheel 32 are mutually coupled and driven, so that the power unit it 33 can directly drive the worm gear 32 to rotate through the worm 31, thereby achieving the purpose of adjusting the intake air amount. On the contrary, with the characteristics of the worm 31 and the worm gear 32, the axial thrust of the worm gear 32 and the reverse force generated by the worm 31 cancel each other, and the reverse force generated by the mast 31 is borrowed. It is provided by the aforementioned thrust bearing c to effectively prevent the worm gear 32 from rotating the worm 31 in turn, so that the worm gear 32 cannot directly drive the worm 31 to rotate to generate a locking action. That is to say, the valve piece 13 of the throttle body 1 cannot directly rotate the shaft 31 through the shaft 12, the rotating shaft 322 and the worm gear 32. Therefore, the throttle body 1 of the present invention can omit the conventional section - 13 - 1280074. The torsion spring member of the valve, the torque of the opening of the door U. J. The power unit 33 drives the large amount of current for the power unit. The control unit 4 does not need to provide a face of 3 and the body of the gas is performed and the force list = 3 ' It is necessary to use _ rod 31 and _ wheel 3;:=^ to achieve a good deceleration effect, so it can also greatly reduce the weight of the body of the present invention, and thus can be applied to the throttle controller of a general locomotive.
