The invention provides a side bearing and a rail vehicle with the side bearing, and the side bearing comprises a base which is provided with a containing groove extending in the vertical direction; the top cover is movably arranged on the base in the vertical direction; the elastic piece comprises a spring and an elastic sleeve, the upper end of the spring abuts against the top cover, the lower end of the spring abuts against the base, the top cover is provided with a mounting column which extends downwards and extends into the containing groove, the elastic sleeve is arranged on the mounting column in a sleeving mode and connected with the mounting column, and the lower end of the elastic sleeve protrudes out of the lower end of the mounting column downwards; an interval exists between the lower end of the elastic sleeve and the bottom wall of the containing groove, the elastic sleeve comprises an inner lining made of a flexible material, a deformation gap exists between the outer side wall of the elastic sleeve and the inner side wall of the containing groove, and the size of the cross section of the mounting column is gradually reduced from top to bottom. Through the technical scheme provided by the invention, the problem that the compression amount and the provided supporting force of the elastic side bearing during working are influenced due to large permanent deformation after the elastic part of the elastic side bearing is compressed in the prior art can be solved.

    本发明提供了一种旁承及具有其的轨道车辆,该旁承包括:底座,具有沿竖向延伸的容纳槽;顶盖,沿竖向可移动地设置在底座上;弹性件,包括弹簧和弹性套,弹簧的上端与顶盖抵接,弹簧的下端与底座抵接,顶盖具有向下延伸并伸入容纳槽的安装柱,弹性套套设在安装柱上并与安装柱相连接,弹性套的下端向下凸出于安装柱的下端,弹性套的下端和容纳槽的底壁之间存在间隔,弹性套包括采用柔性材质制成的内衬套,弹性套的外侧壁和容纳槽的内侧壁之间存在变形间隙,安装柱的横截面的尺寸自上而下逐渐减小。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压缩后永久变形大,影响弹性旁承工作时的压缩量和提供的支撑力的问题。
