Problems solved by technology

Its disadvantages are: most of the rotary position sensors are contact-type, and the accuracy of the output analog signal will be affected due to the wear of the resistive film after repeated use, which in turn will affect the control accuracy of the rotary position of the throttle shaft and the service life of the electronic throttle body; Since the angle of the throttle shaft is controlled by closed-loop feedback, more control time is occupied by the electronic control unit in the control process; the cost of the rotary position sensor is relatively high

Embodiment Construction

[0015] figure 1 , figure 2 Shown is a specific embodiment of an electronic throttle body, including a throttle valve plate 7, a throttle shaft 8, a housing 4, and an air passage 6. The throttle valve plate 7 is fixed on the throttle valve shaft 8 and can be placed in the air passage Turn to change the opening degree of the throttle valve plate. 15 refers to the intake direction of the electronic throttle body. There is a stepper motor 9 with a motor shaft 10 on it, and the throttle valve shaft 8 and the motor shaft 10 are integrated. The throttle rotation position calibration device of this embodiment is a set of rotation position blocking mechanism, which includes a swing arm 14 fixed on the throttle shaft 8 and a stopper 12 fixed on the housing 4, the protrusion of the stopper The height is adjustable and consists of a screw bracket 13 fixed on the casing 4, an adjusting screw 2 and a lock nut 1. Between the swing arm 14 and the spring hanging pin 11 fixed on the shell ...

Abstract

The electronic throttle gate includes valve plate, shaft, casing and gas channel, and the valve plate is fixed to the shaft capable of rotating inside the gas channel. One stepped motor drives the shaft of the electronic throttle gate to rotate, and one rotation position indicator includes at least one triggering signal generator or one rotation position blocking mechanism. The present invention has raised throttle gate shaft position controlling precision, long service life, low cost, open-looped control of shaft position and less control time of the electric control unit.

Description

technical field [0001] The invention relates to the technical field of an electronic throttle body applied to an intelligent management system of an internal combustion engine, in particular to the technical field of an electronic throttle body used in an intelligent management system of a gasoline engine. Background technique [0002] The application of electronic throttle body on the electronically controlled gasoline engine can make the car have functions such as constant speed driving and anti-skid on snow. At present, the Bora sedan produced by Changchun FAW-Volkswagen Company uses the electronic throttle body of German BOSCH company. Its structure and principle are : The inside of the electronic throttle body is an air passage, and there is a throttle valve plate in the air passage, which is fixed on a throttle shaft. The throttle shaft can drive the throttle valve plate to rotate in the air passage, thereby changing the opening degree of the throttle valve plate, reali...
