1. it is the joint part connecting the suspension and balance bar, which mainly plays the role of transmitting the force of the automobile suspension and balance bar;

2. when the left and right wheels pass through the same road surface, the stabilizer bar will not work. However, if the left and right wheels pass through different roads, the horizontal height of the left and right wheels is different, which will cause the torsion of the rod body to produce anti roll resistance and inhibit the rolling of the vehicle body;

3. the balance bar will harden the roadworthiness only when it is applied. Unlike the hard spring, it will harden the roadworthiness comprehensively. If it is necessary to completely rely on the spring to reduce the body roll.
