Comprehensive analysis and solution of various situations in the rear of the car

Damage to the spring and shock absorber caused the tail to sink

The phenomenon of sinking at the rear of the car is generally caused by problems with the rear suspension. The suspension is a component that connects the body and the wheel travel mechanism. One of the main functions is to support the body. The suspension mechanism usually includes three components, one of which is a connecting rod connecting the wheel and the frame, which controls the manner and angle of the wheel movement. The multi-link, double-arm type, etc. that we often hear refer to the connecting rod. The second type is a spring between the connecting rod and the frame, which is used to support the weight of the body and also serves as a cushioning function. The third is a shock absorber, which mainly functions to stabilize the body and reduce shock.

As can be seen from the above, springs and shock absorbers are key components that support the body. When they are damaged, the body will sink due to insufficient support.

Possible problems with springs are: too thin and too soft, excessive stress attenuation, insufficient springs, causing a serious drop in support force, which causes the body to sink; or spring breaks, which directly leads to the body sinking.

The shock absorber is generally the shock absorber that we often say. It relies mainly on hydraulic pressure to achieve the shock absorption function. When there is a problem with its hydraulic mechanism, such as the compression stroke is too short, it is more bumpy or heavy. At the time, there may be a situation that exceeds the limit of the compression stroke of the shock absorber, resulting in a "piercing" phenomenon of the shock absorber, damage to the compression mechanism, and no shock absorption and support, and the body naturally declines.

Serious consequences of sinking at the rear of the car

Sinking at the rear of the car not only affects the aesthetics, but also affects the passing of the car. More importantly, it affects the comfort of the car because its damping performance is reduced or completely ineffective.

The phenomenon of tail sinking is a serious problem. It may not only cause the body to interfere with the wheel, but also pose a danger to driving safety. The best solution is to replace the damaged parts as soon as possible.
