Description

Technical Field

[0002] With the promotion and use of cab suspension products in the automotive field, full-floating cab suspension has become standard in medium and heavy trucks. Full-floating cab suspension connects the cab to the frame through coil springs or air springs, which can attenuate most of the vibrations caused by uneven road surfaces. In order to take into account both smoothness and handling stability, full-floating cab suspensions are equipped with stabilizer bar assemblies to improve the cab's anti-roll performance. The design of the stabilizer bar assembly is directly related to the performance and reliability of the entire cab suspension system. At present, during the use of the stabilizer bar assembly, the downward jump stroke of the cab suspension continues to increase, and the overall Y-direction stiffness of the stabilizer bar assembly gradually decreases, resulting in the common problems of buffer gasket wear, swing arm downward jump limit impact abnormal noise and other faults in the actual use of the traditional stabilizer bar assembly, which results in a very poor user experience.
