Stabilizer Definition
Car stabilizer bar is also called anti-roll bar. It can be seen from the literal meaning that the stabilizer bar is a component that keeps the car stable and prevents the car from rolling too much. The stabilizer bar is an auxiliary elastic component in the car suspension. Its function is to prevent the body from excessive lateral roll when turning, and to keep the body as balanced as possible. The purpose is to prevent the car from tilting laterally and improve ride comfort.
The structure of the stabilizer bar
The stabilizer bar is a torsion bar spring made of spring steel, in the shape of a "U", which is placed across the front and rear suspension of the car. The middle part of the rod body is hingedly connected with the vehicle body or the vehicle frame with a rubber bushing, and the two ends are connected with the suspension guide arm through the rubber pad or the ball stud at the end of the side wall.
The principle of the stabilizer bar
If the left and right wheels jump up and down at the same time, that is, when the body only moves vertically and the deformation of the suspension on both sides is equal, the stabilizer bar will rotate freely in the bushing, and the stabilizer bar will not work.
When the suspension deformation on both sides is unequal and the body is tilted laterally with respect to the road, one side of the frame moves closer to the spring support, and the end of that side of the stabilizer bar moves up relative to the frame, while the other side of the frame moves away from the spring The support, and the end of the corresponding stabilizer bar then move downwards relative to the frame, however, when the body and frame are tilted, the middle of the stabilizer bar has no relative movement to the frame. In this way, when the vehicle body is tilted, the longitudinal parts on both sides of the stabilizer bar deflect in different directions, so the stabilizer bar is twisted and the side arms are bent, which increases the angular stiffness of the suspension.
