Problems solved by technology

Without a shock absorber, the rebound of the spring cannot be controlled. When the car encounters a rough road, there will be serious bounce, and the vibration of the spring up and down when cornering will also cause the loss of tire grip and tracking.

Abstract

The invention relates to a guider, in particular to an automobile shock absorber and belongs to the field of alloy steel materials. The automobile shock absorber guider sequentially comprises a main body core layer made of blister steel and a magnesium alloy surface layer arranged on the surface of the main body core layer from interior to exterior, wherein the thickness of the magnesium alloy surface layer is 4 microns-8 microns. The shock absorber guider which is manufactured through composite materials of the blister steel serving as the main body core layer and the magnesium alloy servingas the surface layer has the characteristics such as high strength, a high melting point and excellent compressive strength of a blister steel core layer material, meanwhile, due to the existence of the magnesium alloy, the automobile shock absorber guider has higher strength and higher rigidity.

Description

[0001] field of invention [0002] The invention relates to a guide, in particular to an automobile shock absorber, which belongs to the field of alloy steel materials. Background technique [0003] The shock absorber of a car is also called "suspension", which is composed of a spring and a shock absorber. The shock absorber is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact. The spring plays the role of easing the impact, changing "one impact with high energy" into "multiple impacts with small energy", and the shock absorber gradually reduces "multiple impacts with small energy". If you've ever driven a car with broken shock absorbers, you can feel the bouncing after every pothole and bump that the shock absorbers are designed to dampen. Without a shock absorber, the rebound of the spring cannot be controlled. When the car encounters a rough road, there will...
