884501634 Truck Solenoid Valve

  The working principle and structure of solenoid valves generally use two-position three-way valves, and some use three-way valves. The gearbox Solenoid valve uses the reversing function of the two-position three-way Solenoid Valve to make the oil pressure of the brake sub-pump continue to reciprocate around the pressurization, pressure holding, and pressure relief, which can reciprocate thousands of times per second, so that the wheels are in a critical state of sliding and locking, so that the wheels have rich adhesion, so as not to let the car lose control when braking.

  The effect of automobile Transmission solenoid valve: automobile transmission solenoid valve can be divided into single solenoid coil solenoid valve and double solenoid coil solenoid valve, which you generally call single coil and double coil; The single-coil solenoid valve changes direction after the spool is energized, but it will be restored after the power is off, and the valve spool changes direction after one side of the double-coil solenoid valve is energized, the spool will not return after the power is off, and the other side of the coil will return after it is energized. To put it simply, it is an electrically controlled switch, the ECU feedback signals through various sensors, determines whether to change gears, and then conducts the oil circuit through the solenoid valve for gear change!
