What is the meaning of car shift lever solenoid valve
Automotive shift lever solenoid valve is a kind of industrial equipment used for automotive shift control. Its main function is to realize the precise control of automotive shift through the automation of electric control fluid. The solenoid valve generates electromagnetic force through the current to control the direction, flow and speed of the fluid, so as to achieve smooth and efficient shift .
Working principle of solenoid valve
Solenoid valve is a kind of valve that generates electromagnetic force through current to control fluid, and can be used in hydraulic and pneumatic fields. In the automobile control system, the solenoid valve works with the circuit to precisely control the direction, flow and speed of the medium to ensure the smooth and efficient shifting process .
The role of solenoid valve in the shifting system of automobile
ensures smooth shift process : the solenoid valve controls the flow of hydraulic oil, adjusts the oil pressure of the gearbox, controls the operation of each component, and ensures the normal operation of the gearbox, so that the shift process is more smooth .
protect the gearbox : The solenoid valve ensures that the gearbox will not be damaged in the process of shifting, enhances the fluency of shifting and improves the driving experience .
safety function : for example, the P stop lock solenoid valve, need to be released after the brake pedal signal is received, to prevent the vehicle from being mistakenly suspended into other gear when starting, to ensure driving safety .
The main role of the shift lever solenoid valve is to help the shift control and ensure the fluency and safety of the shift process . Specifically, the solenoid valve optimizes the smoothness of the shift by adjusting the opening, and the smooth switching of each gear is inseparable from the precise coordination of the solenoid valve .
The working principle and type of solenoid valve
Solenoid valves are the basic components of automation for controlling fluids in industrial equipment controlled by electromagnetism. In the automobile, the solenoid valve is precisely controlled by the transmission Electronic Control module (TCU). The solenoid valve in the automatic transmission is divided into two types: switch type and pulse type:
Switching solenoid valve : through a specific current or voltage to energize the internal coil, drive the needle valve or ball valve displacement, control the oil circuit on and off. This solenoid valve is mostly used to control the shifting process.
pulse solenoid valve : the current duty cycle control mode, through the frequency control to achieve oil pressure regulation. This type of solenoid valve is mostly used for fine adjustment of oil pressure to ensure the smoothness and accuracy of shifting .
The specific application of solenoid valve in the process of automotive shift
During the shift process, the opening of the solenoid valve is adjusted as needed to achieve a smoother shift experience. Different solenoid valves control different clutches or brakes, ensuring stable and reliable switching of each gear.
