What is the position of automobile chassis adjustment in the field of automobile technology?

We often hear from automobile manufacturers and refitting plants that we have readjusted the chassis of new models. It sounds like the chassis has been upgraded by training. However, what is adjustment? Generally speaking, car adjustment is to adjust the chassis and suspension to a certain extent, so that it can achieve the original set effect after adjustment. In fact, does the training chassis really have a great influence on the car? To some extent, it is true. For example, Golf GTI and Golf Club Sport belong to the same chassis setting. However, after the power upgrade and the hard adjustment of engineers, the golf club Sport has refreshed the title of "the fastest pioneer" (once), which shows that "adjustment" is very useful.

Generally speaking, the adjustment of the chassis has an important relationship with the body structure, which is related to the design of the body structure, the design of the subframe, the material (material) of the chassis, the layout of the chassis, or the modified parts, which will affect the dynamic performance of the automobile. To put it simply-good body rigidity can prevent the frame from deforming due to high-speed cornering, the subframe can suppress the vibration of the road to the engine, and the weight of the body directly affects the speed-up time of the car.

The common chassis adjustment is to adjust the double A-arm, McPherson or multi-link structure in the suspension system, and different suspensions affect its dynamic performance. Many performance cars will be made of aluminum alloy, which is to reduce the weight, reduce the burden, and improve the handling response of the car cornering.

The most common adjustment (modification) is the upgrade of shock absorber. Shock absorber is divided into two main parts-shock absorber core and shock absorber spring. Shock absorbers and springs are responsible for absorbing the vibration of the road surface. The degree of inflation and rebound of the shock absorber core will determine the comfort and handling, and the shock absorber is also responsible for the forward and backward movement of the center of gravity of the vehicle. Therefore, it is not difficult to imagine that the damping, stroke and spring length of the shock absorber will have an impact on the control. Let's just say that the hard-tuned shock absorber will directly feed back the road information to the car, because "hard" can't filter out too much vibration.
