Shift electromagnetic What is a valve?
In gear /The left end of the shift valve is connected to the shift solenoid valve through the oil line. When the solenoid valve is closed, there is no oil pressure acting on the left end of the shift valve, and the shift valve moves to the left end under the action of the spring force on the right end;when Solenoid Valve is opened, the main oil line pressure oil acts on the left end of the shift valve through the solenoid valve, causing the shift valve to overcome the spring force and move to the right end, thereby causing oil line change and realizing gear shifting.
The shift solenoid valve is broken What will happen if the shift solenoid valve is broken?
1. The piston of the vibration damping pressure accumulator is stuck and cannot dampen the vibration.
2. The main oil line pressure regulating valve is faulty , causing the main oil line oil pressure to be too high.
3. The steel ball of the one-way valve is missing. The shift actuator engages too quickly.
4. The engine idle speed is too high.
5. Throttle valve cable or throttle position Improper adjustment of the sensor causes the oil pressure in the main oil line to be too high.
If the shift solenoid valve is faulty, the transmission may suffer from stalling, slippage, impact when entering gears, and failure to shift up, etc. It is recommended that car owners conduct timely maintenance to avoid causing greater damage to the vehicle.
Pass the controlled medium (pressure liquid, gas air, pressure value is the middle value of the pressure range of the solenoid valve) to the solenoid valve, and then Solenoid valve coilWhen energized, if the controlled medium changes from on to off or from off to on, then the solenoid valve is good. When the pressure of the medium passed by the solenoid valve is normal, if you press the red manual button of the solenoid valve, the solenoid valve does not respond, and the pressure medium does not change on and off, indicating that the valve core is bad.
Solenoid valve The solenoid coil is energized and generates magnetic attraction that overcomes the pressure of the spring and drives the valve core to move. It has only one solenoid coil with a simple structure and can only realize switching. The valve stem is driven by the electric motor to drive the valve core to move. Electric valves are divided into shut-off valves and regulating valves. The shut-off valve works in two positions, that is, fully open and fully closed. The regulating valve is equipped with an electric valve positioner on it, and the valve is dynamically stabilized in one position through closed-loop adjustment.
