Car shock absorber application
What is a car shock absorber?

Car spring assist is a mechanical part that is used to reduce the effects of road roughness on the room and passengers of the car. Due to the variable length and flexibility of the internal components, the shock absorber has the property of shock absorption. The purpose of using shock absorbers is to increase the comfort of passengers and the safety of cars. Also, this part reduces the depreciation of other parts of the car by absorbing shocks and reducing strong shocks.

The application and function of the shock absorber

Car spring help reduces the effect of road fluctuations and shocks on the car body by creating pressure or tension on the parts connected to it. This part, which is located near the wheels, should dampen the oscillations of the existing springs. By maintaining the balance and stability of the car in different modes of movement, the shock absorber reduces the possibility of road accidents. If a car does not have shock absorbers, when going over bumps, all the shocks will be transferred into the room and the passengers, which is definitely very annoying. In addition, if the shock absorber is removed, the wheels of the car lose contact with the ground in the face of successive bumps. It is clear that in such a situation, the balance of the car is disturbed and it deviates from the path or overturns.

In general, the functions of the shock absorber are:

Increasing the comfort and safety of car passengers by reducing body vibrations and oscillations Preventing unwanted car movement during hard braking or sudden acceleration Protection of parts and other components of the car against transfer shocks from the road surface Reducing wheel oscillations while driving on uneven surfaces and maintaining their contact with the ground Controlling the balance of the car while traveling on winding roads

How the shock absorber works

Car wheels are always in contact with the road and create vibrations when passing over unevenness and bumps. These vibrations cause the car spring to withstand more pressure and tension. The spring transfers this energy to the head ball of the car shock absorber. This part, in turn, sends energy to the auxiliary shaft and the piston inside the shock absorber. By moving inside a chamber containing a special fluid (usually oil), the piston tries to pressurize this fluid. But because the fluid is not compressible, the piston has to face a lot of resistance. To reduce this resistance, the fluid is transferred to the other part of the chamber through small piston valves. This hard movement consumes a large part of the energy and turns it into heat. As a result, the movement of the piston and control assist shaft and shocks are less transferred to the car body and passengers. In the movement of the car shock absorber, two compression and expansion cycles occur, which are determined depending on the direction of the piston movement. When the piston moves down, the fluid below it is compressed and the compression cycle takes place. This cycle controls the unsprung weight of the car. As the piston moves up, the fluid above it is compressed and the expansion cycle takes place. This cycle controls the suspension weight of the vehicle. The resistance in the expansion cycle is higher than the compression cycle.

Proper maintenance of car shock absorbers

By observing some points, the useful life of car shock absorbers can be increased. These points include: Do not carry extra and non-standard loads by car. Any increase in weight increases the pressure on the shock absorbers and reduces their useful life. Avoid driving on rough and bumpy roads as much as possible. Obviously, in such routes, the shock absorbers suffer much more shocks. If for any reason you have to cross these types of roads, you should drive calmly and patiently to reduce the pressure and shocks on the shock absorbers. In addition to increasing wear and tear on braking system components, heavy braking imposes additional pressure on the suspension system, especially the shock absorbers. Therefore, it is necessary to avoid moving at an illegal speed and sudden brakes as much as possible. Adjusting the tire pressure makes the wheels stick to the road better and the shock absorbers work more easily. Also, by periodically balancing the wheels, it is possible to prevent the increase of vibrations and adverse shocks to the car. This in turn takes the extra stress off the shock absorber. The softer and better quality car tires are, the better they can absorb bumps and small bumps. When the useful life of the car tire is over, it should be replaced as soon as possible. Old and hard tires transfer the shocks and bumps of the road more to the shock absorbers, which naturally affects the life of the car's shock absorber.
