What are the symptoms of a broken front shock absorber? The performance of a broken front shock absorber of a car

As the most important part of the automotive shock filter system, the automotive shock absorber is responsible for absorbing the vibration and impact caused by the uneven road surface when the vehicle is running, so as to provide a good ride comfort for the vehicle driver and occupants. Once the shock absorber is damaged, it will be greatly affected whether it is the driving texture of the vehicle or the driving safety.

In order to be able to help everyone in the process of driving earlydiscover, Solve it early, let's take a look at the symptoms of (front) shock absorber failure.

(Front) Symptoms and manifestations of a broken shock absorber

Abnormal sound:If the shock absorber makes abnormal noise when the vehicle is driving on a bumpy road section, it is most likely that the shock absorber is damaged.

Oil spill:Check the shock absorber through the wheel arch with a flashlight. When oil leakage is found outside the shock absorber, it indicates that the shock absorber has been damaged.

Loose chassis:When the vehicle is driving on a bumpy road section, if the body posture is found to be excessively bumpy and swaying, it is generally also a problem with the shock absorber.

Expanding knowledge: how shock absorbers work

At present, most vehicles use hydraulic shock absorbers, and their working principle is very simple.

The upper support of the shock absorber is integrated with the piston and the piston rod and is connected to the vehicle body; the lower support is integrated with the pressure cylinder and is connected to the lower control arm of the frame. When the vehicle undergoes relative movement due to vibration, the piston inside the shock absorber will move up and down, forcing the hydraulic oil in the oil cavity to flow from one cavity to the other cavity from the piston bypass valve repeatedly, and follow the bypass valve The friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, which converts the energy of the vibration into heat and dissipates it into the atmosphere.
