Abstract

本实用新型提供一种曲面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,钢轨的轨面横截面上具有凹陷和凸出结构。本实用新型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,都有积极的意义。

Description

一种曲面钢轨
技术领域
本实用新型属于一种钢轨。 
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
本实用新型要解决的问题是提供一种曲面钢轨,尤其适合铁路铺设时使用。 
为解决上述技术问题,本实用新型采用的技术方案是:一种曲面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,钢轨的轨面横截面上具有凹陷和凸出结构。 
凸出结构设置在钢轨轨面的中间。 
本实用新型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,都有积极的意义。 
附图说明
图1是本实用新型的横截面结构示意图 
具体实施方式
如图1所示,本实用新型为一种曲面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,钢轨的轨面横截面上具有凹陷和凸出结构。 
凸出结构设置在钢轨轨面的中间。 
以上对本实用新型的一个实施例进行了详细说明,但所述内容仅为本实用新型的较佳实施例,不能被认为用于限定本实用新型的实施范围。凡依本实用新型申请范围所作的均等变化与改进等,均应仍归属于本实用新型的专利涵盖范围之内。 

Claims (2)

1.一种曲面钢轨,由钢轨轨面、钢轨侧面,钢轨腰部、钢轨底部构成,其特征在于:钢轨的轨面横截面上具有凹陷和凸出结构。
2.如权利要求1所述的曲面钢轨,其特征在于:所述凸出结构设置在钢轨轨面的中间。
