Abstract

本发明提供一种凸面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,钢轨的轨面横截面中间具有凸出结构。本发明的有益效果是钢轨制作过程简单可靠,能增大轮轨之间的接触面积,对防止车轮打滑及防止车轮爬轨、减小噪音等都有积极的意义。

Description

一种凸面钢轨
技术领域
本发明属于一种钢轨。
背景技术
目前,铁路钢轨大体是工字型结构,轨面呈弧形。由于钢轨硬度高于轮子硬度,轮子的实际踏面,会发生变形。在高速、重载的情况下,会更明显。这种形变,会朝一定的方向积累,积累到一定程度,影响行车安全。
发明内容
本发明要解决的问题是提供一种凸面,尤其适合铁路铺设时使用。
为解决上述技术问题,本发明采用的技术方案是:一种凸面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,钢轨的轨面横截面中间具有凸出结构。
进一步,凸出结构为半圆形。
本发明具有的优点和积极效果是:由于采用上述技术方案,钢轨制作过程简单可靠,能增大轮轨之间的接触面积,对防止车轮打滑及防止车轮爬轨、减小噪音等都有积极的意义。
附图说明
图1是本发明的横截面结构示意图
图中:
具体实施方式
如图1所示,本发明为一种凸面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,钢轨的轨面横截面中间具有凸出结构。
凸出结构为半圆形,增大了轮轨之间的接触面积。
以上对本发明的一个实施例进行了详细说明,但所述内容仅为本发明的较佳实施例,不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等,均应仍归属于本发明的专利涵盖范围之内。

Claims (2)

1.一种凸面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,其特征在于:钢轨的轨面横截面中间具有凸出结构。
2.根据权利要求1所述的凸面钢轨,其特征在于:所述凸出结构为半圆形。
