Working principle of automobile spring shock absorber

With the development of economy, car, as an important means of transportation, plays a more and more important role in People's Daily life. In the use of automobiles, its safety is a very important issue. As a key component of automobile suspension, automobile spring shock absorber is an indispensable part to ensure automobile safety, and its output and quality have a direct impact on the automobile. Now let's look at how a car spring shock absorber works.

Automotive spring shock absorber is mainly used to inhibit the spring absorption and rebound impact, as well as the impact of the road surface, accelerate the attenuation of the frame and body vibration, in order to improve the ride comfort and comfort of the car; While shock absorber springs filter the vibrations of the road surface, the springs themselves produce reciprocating motion, and car spring shock absorbers are used to inhibit the spring's jumping.

Car is working principle of the shock absorber spring when the frame (or body) and there was a relative motion between axle vibration, piston cylinder, upper middle low still, auto spring shock absorber damping oil through "by valve" within the narrow pore between two isolated cylinder reciprocating flow, due to the friction between the hole wall and the damping oil and liquid molecules formed by the internal friction damping force, In this way, the mechanical energy of the body vibration is converted into heat energy, which is absorbed by the oil and the shock absorber body, and then dispersed into the atmosphere. If the car spring shock absorber is too soft, the body will jump up and down. If the car spring shock absorber is too hard, it will bring too much resistance and prevent the normal work of the spring. In the modification process of the suspension system, the hard car spring shock absorber should be matched with the hard spring, and the hardness of the spring is closely related to the weight of the car, so the heavier car generally uses the hard car spring shock absorber.

The automobile spring shock absorber is an important part of the automobile suspension. The automobile suspension is not only related to the driving comfort of the automobile, but also related to the safety of the automobile. For example, car braking, sharp turns, road bumps, road skidding and other more urgent and harsh conditions, a good suspension system and supporting braking, tires, etc., will play a vital role in the safety of the vehicle!
