The working principle of the gearbox solenoid valve is to adjust the oil pressure and flow in the hydraulic system through electromagnetic control, so as to realize the shift function of the gearbox. ‌‌

The electromagnetic valve of gearbox consists of electromagnetic coil, valve head and valve body. When the electromagnetic coil is energized, it will produce a magnetic field, which will make the valve head subject to magnetic force, thus breaking the seal between the valve head and the valve body. In the process of gear shifting, the control system will judge whether it is necessary to shift gears according to the parameters such as vehicle speed and oil temperature, and control the energization of the solenoid valve through the control signal. After electrifying, the control cavity in the valve body is connected with the corresponding circulation cavity, so that the oil flows according to the set path, thus realizing the shift function.

In addition, the solenoid valve changes the oil pressure by controlling the switch of the oil circuit, thus controlling the opening and closing of the mechanical valve, realizing the switch of the oil circuit and the adjustment of the oil circuit flow. Different solenoid valves control different clutches or brakes and play a role in different gears. Each gear is jointly controlled by one or several solenoid valves to ensure a smooth shift process.

The solenoid valve plays a very important role in the gearbox, which ensures the normal operation of the gearbox by accurately controlling the flow and pressure of hydraulic oil. If the solenoid valve is worn or broken, it may cause problems such as gearbox slipping and gear shifting frustration. Therefore, maintaining the normal working state of the solenoid valve is very important for the performance and life of the gearbox.
