Whether it is DCT, AT or CVT transmission, the hydraulic system is indispensable for mainstream technical solutions. In the hydraulic system, the solenoid valve serves as an actuator to convert electrical signals into hydraulic signals and control the pressure and flow in the hydraulic system. It is a key component in the hydraulic system. The performance of the hydraulic system directly affects the vehicle's shifting smoothness and fuel economy, and is an important part of the automatic transmission.
The solenoid valve cannot rotate empty without oil pressure, because this can easily cause the motor in the solenoid valve to be damaged by dry burning. The inspection methods of solenoid valve are as follows: 1. Static inspection refers to measuring the resistance value of the solenoid valve when the ignition switch is turned off, connecting the tip of the multimeter to the pins of the solenoid valve, and observing the resistance value displayed on the meter screen. If it is gre…
