Description

A kind of automobile shock absorber integrated with magnetic repulsion and spring

technical field

The utility model relates to the technical field of auto parts, in particular to a magnetic repulsion and spring integrated automobile shock absorber.

Background technique

In various vehicles such as automobiles, most of them are equipped with shock absorbers, the purpose of which is to reduce the shock and improve the stability of the vehicle body.

At present, there are many automobile suspension damping technologies, all of which are aimed at comfort and stability. Comfort depends on the compression coefficient of the spring. A spring with a small compression coefficient is comfortable and is commonly referred to as a soft spring. However, the driving stability is poor, and the center of gravity of the vehicle will move outwards and rollover easily on curves, and the unbalanced passenger ride will cause the vehicle body to tilt to the passenger's passenger side. Therefore, the current shock absorber can only put safety first, and then take comfort into consideration. Therefore, all vehicles now use hard springs with a maximum load that is several times the weight of the vehicle itself. The hard spring has a large elastic coefficient, and the corresponding shock absorption and damping are also large. In the current shock absorber technology, the coupling between the damping hole and the spring is very imperfect. On bad roads, the damping is too large, which will cause the spring to expand sluggishly. One bump after another keeps the spring fatigued and overcompressed and loses its damping effect. And the current existing technology is only the magneto-current damping damping shock absorber developed by the United States, and the damping force can be highly coupled with the spring. The built-in radar road scanner computer processes road data at a high speed of 1,000 times per second, and commands the shock absorbers to work, which is expensive.

Shock absorbers are widely used in the automotive industry. The purpose is to quickly attenuate the vibration of the frame and the body, and improve the ride comfort and comfort of the car. The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. In the process of refitting the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the springs is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers. A device connected to the crankshaft that induces vibration is used to counteract the torsional vibration of the crankshaft. 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".

At present, products that have been researched more include spring shock absorbers, nitrogen shock absorbers, gas and oil mixed shock absorbers, and hydraulic shock absorbers. The emergence of these products has solved the problem of vehicle vibration to a certain extent, but due to these There are some problems in the shock absorber itself, which cannot meet the needs of use. For example: short life, not environmentally friendly, etc.
