The invention relates to a quasi-zero stiffness shock absorber for a railway vehicle seat. The quasi-zero stiffness shock absorber comprises a cylindrical hollow belleville spring outer mounting seat with an opening in an upper end, a cylindrical hollow belleville spring inner mounting seat with an opening in a lower end, a belleville spring and a spring damping shock absorption unit, wherein the belleville spring inner mounting seat is buckled in the belleville spring outer mounting seat; two ends of the spring damping shock absorption unit are hinged to the bottom of the belleville spring inner mounting seat and the bottom of the belleville spring outer mounting seat respectively; and the belleville spring is arranged in an annular space between the belleville spring inner mounting seat and the belleville spring outer mounting seat. Compared with the prior art, the quasi-zero stiffness shock absorber has the advantages of simple structure, low cost, easiness in assembly, wide application scene, high reliability, capability of improving the riding comfort of passengers and the like.

    本发明涉及一种用于轨道车辆座椅的准零刚度减振器,该准零刚度减振器包括圆柱形中空且上端开口的碟形弹簧外安装座、圆柱形中空且下端开口的碟形弹簧内安装座、碟簧以及弹簧阻尼减振单元,所述的碟形弹簧内安装座扣设在碟形弹簧外安装座内部,并且所述的弹簧阻尼减振单元两端分别与碟形弹簧内安装座和碟形弹簧外安装座的底部铰接,所述的碟簧设置在碟形弹簧内安装座和碟形弹簧外安装座之间的圆环型空间内。与现有技术相比,本发明具有结构简单成本低、易于装配、应用场景广泛、可靠性高、提高旅客乘坐舒适度等优点。
