What is a strut and when does it need replacing?

Struts are an important part of the suspension system in many vehicles. It serves three main roles:

Supports the car or truck
Absorbs impact from potholes, bumps and other irregularities in the road
Helps vehicle wheels turn when driver turns the steering wheel
A complete strut assembly includes both a spring and a shock absorber.

Struts are cylinder-shaped pistons, with a coiled spring wrapped around a shaft, and filled with hydraulic oil. This heavy-duty coil spring supports the weight of the vehicle and absorbs large bumps.

The strut absorbs most of the weight of the vehicle’s up and down motion when it goes over road bumps, while the shock absorbers dampen the resulting vibrations to stop the vehicle from continuing to bounce up and down after the vehicle clears the road obstructions.

The strut’s spring is very strong, and this compressed spring can be very dangerous if not handled properly. To service the struts safely, Arch Auto Parts uses a spring compressor to compress the spring safely, remove the worn strut, and install the new strut in its place. The spring is then carefully allowed to return to its previous state, and the new strut is ready to support your car or truck and absorb impact from potholes and road bumps again.

Auto Parts Air Struts

A strut is a major structural part of a suspension. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems.
A struts perform two main jobs. First, struts perform a damping function. A piston is attached to the end of the piston rod and works against hydraulic fluid to control spring and suspension movement. Just like shock absorbers, the valving generates resistance to forces created by the up and down motion of the suspension. Also like shock absorbers, a strut is velocity sensitive, so that the amount of resistance can increase or decrease depending on how fast the suspension moves.
A struts also perform a second job. Unlike shock absorbers, struts provide structural support for the vehicle suspension, support the spring, and hold the tire in an aligned position. Additionally, they bear much of the side load placed on the vehicle's suspension. As a result, struts affect riding comfort and handling as well as vehicle control, braking, steering, wheel alignment and wear on other suspension.

What are the advantages of air spring shock absorbers?
I. Advantages and disadvantages: Air damper is the highest vibration isolator with the highest vibration isolation efficiency, better than the spring and rubber, the advantage is that the vibration isolation efficiency is very high, the size is easy to install, the disadvantage is that it takes half a year to check once If the air pressure is small, it will be qi.
Second, the air-shaped damper noun explanation: the air spring shock absorber consisting of an aerial element consisting of three parts of the air chamber, a rubber elastic separator, and a support plate, is an internal inflatable sealed container, which is used to varying the vibration-resistant. . The air spring shock absorber has a lower inherent frequency (2.6 ~ 5.3 Hz), a higher damping ratio (0.06 ~ 0.08), so a higher vibration isolation efficiency air spring shock absorption load change, system inherent frequency It is generally unchanged, so there is a variable stiffness characteristic, so it does not have to consider the center of gravity when the vibration isolating device is designed. The carrying capacity is large and the weight is lighter.
