High-performance anti-loosening rolling brake rail

The invention provides an innovative technology of a high-performance anti-loosening rolling brake rail on vehicle speed reducer equipment of a railway hump marshalling station field, and the innovative technology provided by the invention is characterized in that a steel rail billet is directly used for rolling the brake rail by adopting a die assembly, and an anti-loosening device is arranged ona rail waist surface to form the anti-loosening rolling brake rail. According to the high-performance anti-loosening rolling brake rail manufactured through the innovative technology, the clamping and jumping fault caused by friction impact between vehicle wheels and the brake rail is solved, an S-shaped walking line on the brake rail face is eliminated, and railway traffic safety is guaranteed. 本发明是提出一种铁路驼峰编组站场的车辆减速器设备上高性能防松轧制制动轨的创新技术，本发明提出的创新技术的特点在于：采用模具组件直接用钢轨钢坯轧制制动轨，在轨腰面上安装防松装置，组成防松轧制制动轨。本发明提出的创新技术制造的一种高性能防松轧制制动轨，解决车辆车轮与制动轨磨擦冲击时的夹跳故障，消除制动轨面的S型走行线，保障了铁路行车安全。
