Abstract

The invention relates to a turbocharging electronic actuator and a mounting method thereof, and belongs to the field of electronic actuators. The turbocharging electronic actuator comprises a shell, a motor, an upper cover, a connecting plate, a PCBA circuit board, a magnet, a gear II, a fan-shaped gear, a gear I, a shaft, a dustproof cover, a motor driving gear, an output shaft and a connecting mechanism. The turbocharging electronic actuator is compact in structure, high in control precision, sensitive in control and quick in response, and solves the defects of response lag phenomenon and low precision of a traditional mechanical air release valve. The electronic actuator, provided by the invention, can provide quicker, more stable and more sensitive control to a diesel turbocharger and a gasoline waste gas bypass turbocharger when being applied to a passenger car and a commercial vehicle. Under the condition of the same rated power, the electronic actuator can improve the fuel economy and increase low-speed torque. The electronic actuator realizes the control target through programming the motor driving problem, and uses a sensor for a feedback value of an actuator output position.

Description

technical field [0001] The invention belongs to the field of electronic actuators, in particular to a turbocharged electronic actuator and an installation method thereof. Background technique [0002] The purpose of using a pneumatic actuator in the turbocharger is to ensure that the engine has the best matching effect with the turbocharger in the range of low and medium speeds, so that the engine can get a sufficient amount of air, and the corresponding increase Adapt to the fuel supply, increase low-speed torque, improve fuel consumption, and exhaust air in the high-speed range (that is, part of the exhaust gas directly enters the exhaust pipe without passing through the turbine) to avoid overspeeding of the supercharger rotor or excessive boost pressure And cause the combustion pressure in the cylinder to be too large, aggravate the mechanical load of the engine and so on. That is to say, the turbocharger uses exhaust and purge valves, the focus is to improve the low-spe...
