Problems solved by technology

[0002] The current shock absorbers mainly include spring shock absorbers and pneumatic shock absorbers. Among them, the support force of spring shock absorbers is relatively small, so the application occasions of spring shock absorbers are limited, and the number of uses of springs will reach After a certain degree, metal fatigue occurs and fails; while the pneumatic shock absorber needs to be filled with liquid nitrogen at low temperature and converted into high-pressure gas at room temperature, and the cylinder and piston used have high processing precision, complicated production and high cost. In addition, pneumatic shock absorbers are also dangerous in high-temperature environments. After a long time of use, high-pressure gas leakage will occur due to the aging of the seals, which will cause the shock absorbers to fail; in addition to the above two types of shock absorbers, there is another A hydraulic shock absorber is driven by liquid, so the structure of the liquid shock absorber is more complicated, and the hydraulic shock absorber is characterized by strong support, but slow movement, and the application occasion is also different from the above two shock absorbers. Shock absorbers are not the same, in view of this, after observing the above-mentioned shortcoming, the creator of this case thinks that the known shock absorbers really need further improvement, and the present invention produces one by one

Abstract

The invention discloses a magnetic suspension shock absorber. The magnetic suspension shock absorber is mainly composed of an outer sleeve cylinder, a shaft rod, an inner sleeve cylinder and two groups of magnetic suspension units, wherein each group of magnetic suspension units is provided with two magnets, the corresponding surfaces the two magnets of the each group of magnetic suspension unitshave same magnetism and are separately arranged on the shaft rod and the inner sleeve cylinder, therefore, when the inner sleeve cylinder is impacted by external force, the two magnets of one of the group of magnetic suspension units are close mutually to generate the action of homopolar repulsion, and thus, the effects of buffering and shock absorbing are achieved.
