Shock absorbers play a role in suppressing the shock of the spring rebounding after shock absorption and the impact from the road surface during the driving process of the car, which is crucial to keep the car running smoothly. Therefore, the manufacturing quality of the shock absorber directly affects the driving performance of the car.
[0003] The solenoid valve is an important component of the intelligent shock absorber. The solenoid valve is combined with the conventional shock absorber to add a bypass oil circuit to the shock absorber. The solenoid valve receives the current control signal of the electronic control unit (ECU) to adjust the pressure difference △P of the shock absorber solenoid valve, control the opening size of the bypass oil circuit, and realize the continuous adjustment of the damping force of the shock absorber. Therefore, the performance of the solenoid valve directly determines the performance of the intelligent shock absorber, and the performance of the solenoid valve is crucial.
[0004] However, in the prior art, the oil flowing into the solenoid valve can only flow into the cavity 33 through the gap between the magnetic core shaft 17 and the bearing 12, and then flow into the cavity 35 through the gap between the magnetic core shaft 17 and the bearing 19. The gaps between the magnetic core shaft 17 and the bearing 12, and between the magnetic core shaft 17 and the bearing 19 are very small, the oil flow is limited, the oil circulation is poor, and the heat taken away is small, which causes the solenoid valve to overheat easily during use.

[0009] Furthermore, grooves are symmetrically formed on the outer side of the bearing outer ring, wherein the number and shape of the grooves are not limited as long as they can form a flow channel.
[0010] Furthermore, the center lines of the pilot valve core and the magnetic core axis coincide with each other.
[0011] Furthermore, the bearing is embedded in the interior of the front support sleeve and the rear support sleeve in an interference fit manner.
