Long stroke magnetic suspension shock absorber

Abstract

The invention discloses a long-stroke magnetic suspension shock absorber. The long-stroke magnetic suspension shock absorber comprises a shock absorbing cylinder (2), and an upper hanging ring (1) and a lower hanging ring (8), which are arranged at two ends of the shock absorbing cylinder, wherein end permanent magnets are respectively arranged inside the upper hanging ring (1) and the lower hanging ring (8); the upper hanging ring (1) is slidably connected with the shock absorbing cylinder (2); the lower hanging ring (8) is fixedly connected with the shock absorbing cylinder (2); suspension permanent magnets and the end permanent magnets repel, and / or the suspension permanent magnets at the two adjacent ends repel each other; and the suspension permanent magnets keep balanced and are suspended between a top permanent magnet (3) and a bottom permanent magnet (7). According to the long-stroke magnetic suspension shock absorber, by using the repelling force of the permanent magnets, a shock absorbing effect is achieved.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a long-stroke magnetic suspension shock absorber. Background technique [0002] At present, in vehicles and other occasions that require shock absorption, a mechanical shock absorber with a spring and a hydraulic piston in parallel is generally used. The spring acts as a buffer, and the piston acts as a damper. The external vibration and impact cause the vibration to have a large attenuation on the shock absorber, so as to maintain the comfort and stability of the vehicle or equipment. After long-term use of this type of shock absorber, the spring in it will relax or be damaged by fatigue due to repeated elastic deformation, making the shock absorber invalid and unusable; the seal of the hydraulic piston will cause oil leakage due to wear and aging , so that the shock absorber loses the effect of the damper. Because it is a contact shock absorber, some high-frequency noise signals generated ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to address the shortcomings and deficiencies of the above-mentioned shock absorbers, and to replace springs and hydraulic pistons with strong magnetic permanent magnet materials with opposite magnetic poles to make a new type of magnetic suspension shock absorber, so as to overcome the existing mechanical shock absorbers. The problems of friction, oil leakage and noise transmission, at the same time, the short stroke and small magnetic levitation force of the previous magnetic shock absorber are solved by adopting the structure of the conical magnet.
