What is the consequence of the car front shock absorber is broken?


If the front shock absorber of the car is broken, the shock absorption effect will be reduced or disappeared. The shock absorption will not restrain the frequency of the spring jump, and the frequency and amplitude of the shock absorber spring beating during the running of the vehicle will be too fast and too large.

The need for the shock absorber is that the spring cannot be stabilized immediately, that is to say, after the spring is compressed and released, it will stretch and contract for a while, so the shock absorber can absorb the vibration caused by the bumpy road surface of the wheel. Make the ride comfortable.

The shock absorber is not used to support the weight of the body but to suppress the shock of the spring rebound and absorb the impact of the road surface. If you drive a car with a broken shock absorber, you can experience the bounce of the car through each hole, after the undulation, and the shock absorber is used to suppress such bounce.

Without a shock absorber, there is no way to control the spring's rebound. When the car encounters a rough road, it will produce a serious bounce. When the corner is bent, the tire's grip and tracking loss will be caused by the vibration of the spring. The ideal situation is to use a shock absorber to limit the bounce of the spring to once.


Extended data

The shape of the shock absorber is a shaft barrel, and there is a movable shaft barrel or a shaft in the shaft barrel. The shock absorber is placed inside the suspension spring and is generally connected to the carriage and the wheel carrier. The principle of air pressure or hydraulic shock absorption is similar.

There are two ways to buffer the sliding of one shaft in the other: one is hydraulic shock absorption, using special hydraulic oil; the other is called air pressure damping, using pressurized nitrogen.

The shock absorber is a two-way motion: when the wheel sinks due to load or braking, the shock absorber is pressurized; when the vehicle returns to its original load, the shock absorber is decompressed. The principle of the shock absorber is actually very simple. When it is pressurized, the lower pressure pipe connecting the wheels rises, pushing the piston into the other barrel connected to the car; the piston has a standard small hole, the oil pressure nozzle is mounted on the hole, and the lubricating oil passes through the hydraulic nozzle The effect of rising to the damping damper. On the contrary, the wheel returns to its original position under the pressure of the suspension spring.

The above is the principle of the hydraulic shock absorber, and the principle of the pneumatic shock absorber is also the same.

The difference is that one end of the gas pressure damper is equipped with a pressurized nitrogen tank. Nitrogen can be compressed and acts as a pressure regulator when pressurized. The advantage is that the use of nitrogen can avoid the emulsification of the old hydraulic shock absorber when the piston is moving too fast.

Due to the application of electronic technology, shock absorbers have experienced a technological revolution. The car has been equipped with an advanced hydraulic shock absorber/suspension spring assembly that automatically adjusts the stiffness during sporty driving, but at a cost.
