Problems solved by technology

[0004] The feature of this solution is that, when the air spring 2A meets the load-bearing requirements, the roll stiffness of the vehicle body is reduced because the air spring 2A is located inside the wheel 5. In this case, to increase the roll stiffness, the air spring 2A must be increased. Rigidity can either increase the roll stabilizer bar or increase the center distance between the air springs 2A. Due to structural limitations, it is difficult to increase the center distance of the air spring 2A in the prior art, so the system is either installed with a roll stabilizer bar. Adding the stabilizer bar will cause Complicate the structure, or increase the stiffness of the air spring 2A.
