Turbo-charged valve controller

Abstract

The invention provides a turbo-charged valve controller. The turbo-charged valve controller comprises an executing component, a driving component, a transmission component, a position detecting component, a control module and a casing component, wherein the executing component is in transmission connection with a turbo-charged valve; the transmission component comprises a power input part and a power output part; the power input part is in transmission connection with the driving component; the power output part is in transmission connection with the executing component; the position detecting component comprises a non-contact magnet type position sensor; and an active cell of the non-contact magnet type position sensor is fixed on the power output part or the executing component. The turbo-charged valve controller provided by the invention can detect the position of the power output part or the executing part in a non-contact manner, does not have abrasion, is good in corrosion resistance, is influenced by the environment extremely lowly, and can perform detection in real time and generate linear execution and detection feedback.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular, to a turbocharging valve controller. Background technique [0002] Existing common automobile turbocharging system, its principle is to use the exhaust gas discharged from the engine as power to drive the worm wheel in the worm gear chamber, and the worm wheel drives the coaxial impeller, and the impeller compresses the fresh air sent by the air filter pipe, and then sends it to the into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the worm gear speed also increase synchronously, the degree of air compression is increased, and the intake air volume of the engine is correspondingly increased, which can increase the output power of the engine. [0003] The turbocharger controller is the most important control unit of the turbocharger system. It obtains signals from the driving computer, converts the signals to control outputs, and contr...

Problems solved by technology

[0006] Disadvantages: If the principle of resistive substrate brush type is used, although the cost is low, the old models have been proved by actual use, with high failure rate, poor reliability, poor corrosion resistance, and great influence by the environment; if the principle of circuit pulse type is used, this principle For staged control and detection, linear control cannot be realized, that is, precise position control and detection cannot be realized

[0010] Disadvantages: After working at high temperature and for a long time, plastic is easy to be damaged due to friction loss, which affects the life of the entire product or system
