Why is the sway bar link always thick before and thin after?

The sway bar link is so good, is it the thicker the harder the better?

In this case, that’s not really the case.

The strength of the sway bar is to let the left and right wheels under the same. If the stabilizer bar is too strong, the left and right wheels will lose too much independence.

From the point of view of comfort, most of the ups and downs on the road are out of sync with the left and right. And the stabilizer bar is too hard to make the comfort worse.

In addition, the sway bar link is also a transmission path of vibration. When the road surface is uneven and the wheels vibrate, especially when the left and right are out of sync. The vibration transmits to the stabilizer bar, and then to the body through the point where the stabilizer bar connects to the body. This is why the stabilizer bar attaches to the body by a rubber bushing, in order to isolate part of the vibration. Speaking of which, by the way: the stabilizer bar bushing is good for comfort. Not necessarily for stability – at the beginning of the body roll, the deformation of the stabilizer bar bushing will be more obvious. And the role of the stabilizer bar will mask. So the trend of competitive modification will often be the stabilizer bar bushing hardened.

As mentioned earlier, the wheels on both sides of the left and right are like a pair of brothers who are not very good. But there is always a reason for the contradiction, and the lateral acceleration generated when turning is this “cause.” Because lateral acceleration causes roll, the resulting force is a moment, called the “roll moment.” This “tilting moment” is bad.

What are the basics for tires? It’s the load, which is this vertical force. With the vertical load, the tire can support the whole car. And can provide longitudinal attachment when braking or accelerating, and lateral attachment when cornering. If there is no vertical load, the slightest movement can make the tire slide.
