Valve block of electronic throttle valve, electronic throttle valve and valve block assembling method

Abstract

The invention discloses a valve block of an electronic throttle valve, the electronic throttle valve and a valve block assembling method. The outer side face of the valve block of the electronic throttle valve is composed of a first inclined face and a second inclined face, and the first inclined face and the second inclined face both incline towards one side of the valve block and are symmetric to each other. The bottom end of the first inclined face and the bottom end of the second inclined face intersect. In the assembling process of the valve block, the mounting direction of the valve block does not need to be recognized, a tool does not need to be adjusted or replaced during type changing and assembling of a gasoline engine electronic throttle valve and a diesel engine electronic throttle valve adopting the valve block, and therefore assembling is convenient.

Description

technical field [0001] The invention relates to an electronic throttle technology of an automobile engine intake system. Background technique [0002] In the engine intake system, the electronic throttle adjusts the engine speed and output power by controlling the amount of intake air supplied to the intake manifold. The electronic throttle adjusts the flow area of ​​air passing through the air passage by controlling the position of the valve plate, and then adjusts the intake air volume. There are two limit positions in the adjustable range of the valve plate 1, which are called the dead center position, and the position where the theoretical flow area is zero is called the bottom dead center position, such as figure 1 shown; top dead center position as figure 2 As shown, it is one of the positions in the range of positions where the theoretical flow area is the largest. [0003] At present, the electronic throttle can be used on two platforms of gasoline engine and die...

AI Technical Summary

Problems solved by technology

Therefore, in order to ensure that the positions of the bolts of the two electronic throttle valves are consistent, the installation form of the positioning tool needs to be replaced when switching between the two electronic throttle valves during the production process, and the position of the fixture also needs to be adjusted to ensure that the product is installed on the tooling After turning the valve plate to the corresponding bottom dead center position, the valve plate is in the horizontal direction, the ejector rod of the tooling can play a supporting role on the valve plate, and the position of the electric torque gun does not need to be changed, but this will lead to Tooling replacement is more cumbersome
