Abstract

一种车顶上边梁，包括车顶上边梁本体，其特点是：车顶上边梁本体为整体成型且连续通长的不等边角形的构件，其中一边为弧形。本实用新型提高了强度、刚度，达到了国际通用技术标准的要求，提高了国产铁路客车的技术水平和等级。

Description

车顶上边梁
技术领域：
本实用新型涉及铁路主型客车车体冷弯型钢，尤其是涉及一种车顶上边梁。
背景技术：
按照国际铁路权威性动车组和客车车体强度、刚度设计标准要求，车体钢结构除了能够承受沿车钩缓冲装置纵向中心线作用的1500kN纵向压缩载荷外，还须在车顶与侧墙结合处能够承受300kN的纵向压缩载荷。而传统车顶上边梁是分段压型后再拼接组焊成直角，与侧顶板结合后有间隙，影响强度，因而不具备满足上述车体强度设计要求的能力。
发明内容：
本实用新型所要解决的技术问题是提供一种结构强度、刚度水平高的车顶上边梁，以克服背景技术存在的缺陷。
本实用新型的技术方案是：包括车顶上边梁本体，车顶上边梁本体为整体成型且连续通长的不等边角形的构件，其中一边为弧形。
本实用新型车顶上边梁为整体成型且连续通长的不等边角形的构件，其中一边为弧形，因此，提高了强度、刚度，达到了国际通用技术标准的要求，提高了国产铁路客车的技术水平和等级。
附图说明：
附图是本实用新型的结构示意图。
具体实施方式：
参照附图，本实用新型包括车顶上边梁本体1，车顶上边梁本体1为整体成型且连续通长的不等边角形的构件，其中一边2为弧形。
