The stand is one of the most viewsshock absorbers used today on all traction machines. The stand is placed on steering knuckle holder which is connected by a hinge to the lower suspension arm.

This item is part of the structure itself podcast ; it can be replaced with an upper suspension arm and ball joint for some suspensions. However, the rack has less weight and she takes less space than other types of pendants. For these two reasons, it is more commonly used.

Typically, the strut consists of Spring that can support the weight of the vehicle and the shock absorber strut crankcase and shock absorber cups with a shock absorber, the role of which is to perform control of the movement of the spring and suspension.

The stand is used for the following two functions:

• Amortization assistance : works in conjunction with shock absorbers;
• Agreement tire : By supporting the lateral weight of the vehicle, it maintains tire alignment and provides driving comfort.

The rack is an important part to ensure driving a vehicle, its handling, its braking, and the geometry of its wheels.

🔎 How does the rack work?

The strut looks like a normal shock absorber. There are two types of spacers:

1. Sealed spacer : The upper leg is always in the closed position, so access to the shock cartridge inside the leg is not possible. Therefore, in the event of a shock absorber malfunction, the strut must be replaced.
2. Repairable rack or replacement cartridge : The upper part of the support tube is protected by a rod and a threaded sleeve. Thus, it is possible to replace the damper cartridge. The shock absorber is filled with oil to lubricate the inner wall, the seal is provided by an O-ring.

The piston at the end of the piston rod will push hydraulic fluid to provide movement of the spring and therefore the suspension. The strut is equipped with a valve system that prevents the suspension from increasing or decreasing travel speed.

Through this system, he will apply more or less strong pressure to slow down the car and ensure its control by the driver.

• Braking is dangerous : when braking, you feel the car bouncing off the ground or losing traction.
• Aquaplaning risk : In case of rain, even if you are driving slowly, you may find yourself in an aquaplaning situation.
