The main structure includes a damper, a spherical plain bearing, a hexagon nut, a stop washer, a circlip and a fixed shaft. The damper, the fixed shaft, the spherical plain bearing and other related components are assembled into a shock damping device, which is connected between two car bodies of a rail vehicle. By the rotation of the spherical plain bearing and the compression of a highly elastic damping ring in the damper, the impact kinetic energy during vehicle operation is absorbed, and the impact vibration generated by a series of working conditions such as rotation, rolling, pitching, acceleration and braking during vehicle movement is effectively absorbed. At the same time, the highly elastic damping ring made of self-lubricating material greatly reduces the friction between it and the external cylinder barrel, realizing long-term maintenance-free of the damping main body; its structure is simple, the maintenance is convenient, the highly elastic damping ring is fully isolated from the external environment, has good weather resistance, greatly improves the service life, and meets the requirement of long-term maintenance-free.

[0004] During the use of the above shock damper, the damping ability is fixed, and it is thus difficult to adjust according to actual use requirements, so that it has certain limitations during use and is difficult to meet actual use requirements. Summary of the Invention

[0005] The purpose of the present invention is to provide a solenoid valve structure for shock absorber damping control to solve the defect that the existing shock damper is not convenient for damping adjustment.

[0009] The adjusting structure includes a built-in groove formed on one side inside the connecting seat. An adjusting groove is provided inside the built-in groove, and an electromagnetic coil is arranged inside the adjusting groove. A flow-blocking column is fixed to one side of the electromagnetic coil. A return spring is formed inside the connecting seat on one side of the adjusting groove.
