The structure of the oil damper is similar to that of the suction pump. In the same place, only the upper part of the steel body of the hydraulic shock absorber is closed, while the gate valve has a small round hole. When the rear tire is damaged by bumping on the ground, the cylinder liner moves upward the liner inside the piston rod moves downward. At this time, the piston gate valve is turned upward, the oil on the left side of the piston rod in the cylinder liner cavity of the spring damper bearing will flow into the upper part of the piston rod by all friction resistance. In addition, this part of the oil is also injected into the oil chamber between the inner outer cylinder liners according to the small round hole on the bottom gate valve. In this way, the attenuation coefficient is reasonable to deal with the impact load of the car on the convex concave roads. When the wheel turns over the raised road to land, the cylinder liner will follow the downward fitness movement, the piston rod will move up relative to the cylinder liner. When the piston rod moves upward, the gate valve at the bottom of the oil refining opening flows into the inner cylinder liner. In addition, the oil above the piston rod of the inner cylinder liner flows into the lower side through the small round hole beside the piston valve. The working principle of shock absorber bearing at this time, when the hydraulic oil passes through the small round hole in the whole process, it will suffer very large friction resistance, which will create a good damping effect, with the purpose of shock absorption.
