摘　　要：介绍了空气弹簧采用沙漏式辅助弹簧的结构特点。理论分析和试验结果证明,沙漏式辅助弹簧方案不仅可以有效降低空气弹簧的垂向刚度,而且还可以提高车辆在无气运行时的动力学性能。The structure features of the hour-glass auxiliary springs applied in air springs are described. The theoretical analysis and test result show that the hour-glass auxiliary springs can not only reduce the vertical stiffness of air springs effectively, but can also improve the dynamic performance of vehicles in operation with no air in air springs.
