Therefore, selecting the appropriate hardness of the stabilizer bar bush is crucial to ensure the normal function of the stabilizer bar system.

[0003] In the process of adjusting the suspension of the vehicle chassis, each component part of the suspension needs to be installed and matched, and each kind of part has several to tens of different parameter options, among which the stabilizer bar bush is also the same. If the previous adjustment method is followed, the stabilizer bar bush with different stiffness needs to be replaced for many times under the condition of only considering the difference of the bush itself, and if the matching with other parts is also considered, the number of replacement times will be multiplied, which will bring huge workload to the suspension adjustment and affect the project progress. In order to compress the suspension adjustment period, a new stabilizer bar bush stiffness adjustable structure needs to be designed to reduce the workload of the suspension adjustment. SUMMARY

[0012] 1. The utility model can improve the tuning efficiency of suspension, and does not need to frequently disassemble stabilizer bar bushing and peripheral associated parts during tuning. In the utility model, when the stiffness of the bushing needs to be adjusted, we only need to rotate the two fixed bolts to change the compression amount of the pad plate, and then change the pressure between the vehicle frame and the bottom of the bushing and the compression amount of the bushing. By rotating the pressing bolt at the top of the clamp main body, the pressing bolt is rotated up and down, the downward pressure of the pressing plate on the bushing is changed, and then the compression amount of the bushing is changed. By changing the pressing force on the upper and lower sides of the bushing, the compression amount of the bushing can be changed, and then the stiffness of the bushing can be changed, so that the purpose of changing the hardness of the bushing without disassembling the stabilizer bar bushing and peripheral associated parts can be achieved.
