Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] Please refer to figure 1 and figure 2 , figure 1 It is a cross-sectional view of a specific embodiment of the electronic throttle provided by the present invention, figure 2 for figure 1 A top view of the electronic throttle shown.

[0020] In a specific embodiment, the present invention provides an electronic throttle, including a throttle body and a servo motor; the throttle body includes a throttle body 10, a throttle shaft 6, a bearing 8 and a throttle 9, Driving the throttle shaft 6 can change the position of the throttle 9, and the position of the throttle 9 determines the opening and closing angle of the channel state of the throttle body 10...

Abstract

The invention discloses an electronic throttle valve which comprises a throttle valve body and a servo motor. The throttle valve body comprises an air throttle main body, a throttle valve shaft and athrottle valve main body. The position of the throttle valve main body can be changed by driving the throttle valve shaft, and the magnitude of the opening-closing angle of a channel of the air throttle main body is decided by the position of the throttle valve main body. The servo motor comprises a driver, an encoder and a motor body, the drivers controls the rotation angle of a motor, the motorbody directly drives the throttle valve shaft, and the encoder feeds back the actual rotation angle of the motor to a driving plate. According to the electronic throttle valve, the rotation angle of the throttle valve main body is directly driven by the servo motor, the throttle valve is composed of the servo motor and the throttle valve body, the structure is compact, and the size is small; during working, three-ring control specific to the servo motor is achieved so that the rotation position of the valve can be more accurately controlled, and the motor can further be protected against burning up by limiting the maximum current of the motor; and the control response speed of the electronic throttle valve is high, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electronic throttle. Background technique [0002] The throttle valve is a controllable valve that controls the air to enter the engine. After the gas enters the intake pipe, it will mix with gasoline to become a combustible mixture, which will be burned to form work. It connects the air filter on the top and the engine block on the bottom, which is called the throat of the car engine. [0003] The traditional pull-wire throttle is controlled by a mechanical link mechanism, which also includes springs, pulleys and other parts, which is noisy. Since the entire operation process is completed through the link mechanism, the response time lags and cannot Precisely control the opening and closing angle. [0004] In order to overcome the above shortcomings, an electronic throttle valve is designed. The electronic throttle valve drives the throttle valve opening through a micro...
