description

Engineers designed shock absorbers and springs in the suspension, both of which have gradually become important parts of the car’s suspension structure.
There are many types of springs, such as coil springs, torsion bar springs, leaf springs, rubber springs, and gas springs. The longest type of car suspension is the coil spring. Here is an example of the most common coil spring to explain the difference between the two.
The car coil spring is not particularly magical, that is, it is larger than the spring we played when we were young, and the principle is basically the same. The spring is an energy storage element, which can cushion the effect of external forces. As for the cushioning of the spring, in fact, everyone is familiar with it. Many basketball shoes will use an air cushion spring design at the bottom to achieve a cushioning effect.
But the buffer can’t exhaust the energy. Because of the structure, the energy will be completely released. With no support, the spring is easy to fluctuate up and down, left and right, and it is difficult to ensure the driving stability of the car. Because the spring is “unreliable”, we need to design a device to consume this energy.
At this time, the shock absorber comes in handy. The function of the shock absorber is simply the friction between the valve wall and the hydraulic oil and the internal friction between the hydraulic oil molecules to form damping, convert the vibration energy into heat energy, and then be absorbed by the outer wall of the shock absorber and emitted to the outside world in the air. The energy of the vibration is converted into heat energy to dissipate, so that the force vibration will not be transmitted to the car body, and the passengers in the car will not feel that the car is particularly bumpy when driving.
Automobile vibration energy is often very large, and the beating speed is very fast. If there is no spring buffer, the energy consumption stroke of the shock absorber is extended. It is expected that the shock absorber will consume all the vibration energy in a short stroke, and the difficulty will be greatly increased. . Therefore, the cooperation between the spring and the shock absorber has become particularly important.
The spring is actually quite useful. For example, the ratio of the sprung mass to the unsprung mass has a greater impact on the vibration of the car. The larger the value, the smaller the vibration of the car when passing through a bumpy road, and vice versa.
According to the characteristics of the two, the timing of their action is slightly different: the spring plays the main role during the compression stroke, and the damping force of the shock absorber is small, so as to give full play to the elastic effect of the elastic element and alleviate the impact; damping vibration during the extension stroke The main function of the shock absorber is that the spring releases elastic potential energy, and the damping force of the shock absorber becomes larger, which quickly consumes energy to reduce vibration.
The two need to be coordinated well. For example, if the shock absorber is too soft, the body will jump up and down, and if the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly.
Of course, there are cases where the shock absorber + spring combination is not used. For example, active suspensions usually replace a set of springs and shock absorbers with a hydraulic or pneumatic suction tube. It is said to be active because it can actively adjust the height and hardness of the suspension according to the road conditions, so that the car can maintain better stability and comfort under different conditions.
