The invention provides an elastic side bearing and a rail wagon with the elastic side bearing, and the elastic side bearing comprises a base which is provided with a mounting groove extending in the vertical direction; the top cover is movably arranged on the base in the vertical direction, and the top cover is provided with a mounting column which extends downwards and extends into the mounting groove; the elastic column is arranged in the mounting groove, the lower end of the elastic column abuts against the base, the upper end of the elastic column abuts against the top cover, and the elastic column is made of an elastic material; the elastic sleeve is arranged on the mounting column in a sleeving mode and connected with the mounting column, the outer side wall of the elastic sleeve is in sliding fit with the inner side wall of the mounting groove, and the groove bottom of the mounting groove is provided with a limiting part capable of abutting against the lower end of the elastic sleeve; the vertical interval between the lower end of the elastic sleeve and the limiting part is smaller than the vertical interval between the lower end of the mounting column and the bottom wall of the mounting groove. Through the technical scheme provided by the invention, the problems of unreliable performance parameters, too small vibration isolation frequency range, non-adjustable rigidity and the like of the elastic part of the elastic side bearing in the related technology can be solved.
本发明提供了一种弹性旁承及具有其的铁路货车,该弹性旁承包括:底座,具有沿竖向延伸的安装槽;顶盖,沿竖向可移动地设置在底座上,顶盖具有向下延伸并伸入安装槽的安装柱;弹性柱,设置在安装槽内,弹性柱的下端与底座相抵接,弹性柱的上端与顶盖相抵接,弹性柱采用弹性材质制成;弹性套,套设在安装柱上并与安装柱相连接,弹性套的外侧壁和安装槽的内侧壁滑动配合,安装槽的槽底具有能够与弹性套的下端相抵接的限位部,弹性套的下端和限位部之间的竖向间隔小于安装柱的下端和安装槽的底壁之间的竖向间隔。通过本申请提供的技术方案,能够解决相关技术中的弹性旁承的弹性件的性能参数不可靠、隔振频率范围过小以及刚度不可调节等问题。
