Track shock absorber
The invention provides a rail shock absorber which comprises a metal plate, a buffer layer is arranged on the bottom face of the metal plate, a steel rail bearing block used for installing a rail and an elastic strip connector are arranged on the top face of the metal plate, a circular truncated cone type limiting hole is formed in the metal plate, and the inner side wall of the circular truncated cone type limiting hole is connected with a limiting circular truncated cone through the buffer layer. A spike mounting hole is formed in the circular truncated cone type limiting hole, and the axis of the circular truncated cone type limiting hole, the axis of the limiting circular truncated cone and the axis of the spike mounting hole coincide; according to the rail shock absorber, low vertical rigidity can be provided, the geometric shape and position of a steel rail are controlled, and meanwhile the size of the rail shock absorber is effectively reduced.
本发明提供了一种轨道减震器，包括金属板，所述金属板的底面上设有缓冲层，金属板的顶面上设有用于安装轨道的钢轨承轨块及弹条接口，所述金属板开设有圆台式限位孔，所述圆台式限位孔的内侧壁通过缓冲层连接有限位圆台，所述上开设有道钉安装孔，所述圆台式限位孔、限位圆台及道钉安装孔的轴心线重合；本发明提供的轨道减震器能提供较低垂向刚度，控制钢轨几何形位，同时有效的降低轨道减振器体积。
