进一步的，斜向支撑梁夹角的优选范围为62°-68°。
本发明还保护一种轨道车辆，其特征在于：包含有上述的轨道车辆无枕梁底架端部结构。
所述轨道车辆无枕梁底架端部结构的生产工艺，包括以下步骤：
第一步、将车钩安装座、车钩支撑梁和斜向支撑梁焊接成形成主框架，车钩支撑梁之间形成开口向前的55°-80°夹角，斜向支撑梁之间形成开口向后的120°-140°夹角；

具体实施方式
下面结合附图对本发明的实施方式做解释说明。
如图1、图2、图3所示，本实施例轨道车辆无枕梁底架端部结构,包括底架端梁1、底架边梁7、底架地板9、车钩安装座3，两个前部支撑梁2、两个车钩支撑梁4、车钩连接座5、牵引梁6和前端连接板8，如图1所示。每个部件为单独焊接或单独加工，然后进行组焊。车钩安装座3，两个前部支撑梁2、两个车钩支撑梁4、车钩连接座5和牵引梁6焊接于底架地板9的底面(下表面)。
车钩安装座3的前部通过斜向支撑梁2与底架端梁1连接，车钩安装座3的两侧通过车钩支撑梁4与底架边梁7连接，形成主框架，使车钩安装座3两侧分别形成四边形框架结构，有利于力的传递。其中，两根斜向支撑梁2形成开口向前的65°夹角(斜向支撑梁的夹角范围在55°-80°，优选范围为62°-68°)，两根车钩支撑梁4形成开口向后的130°夹角(车钩支撑梁的夹角范围在120°-140°比较合适)。前部支撑梁2通过前端连接板8与底架边梁7连接，扩大了车辆在受力时的传力面积。同时此连接未对防爬器或引上线空间造成影响。
两个前部支撑梁2与车钩安装座3连接形成一定角度，可根据车钩摆动空间对角度进行调整，有力保证了车钩的运动空间和安装空间。车钩安装座3通过型材和板材连接。车钩接口由型材直接挤出，避免了焊接。挤出的型材采用“Y型”结构有利于纵向力的传导。如图2所示。车钩安装座3后方设置车钩连接座5，车钩连接座5采用板材连接，形成平缓的框架连接结构，有利于纵向力的承载。车钩安装座3内部隔板进行了开孔，保证了车辆碰撞时车钩退钩空间，也保证车钩不掉落轨道形成次生灾害。
牵引梁6前端与车钩连接座5焊接，并且牵引梁6与底架地板9进行连接，通过连接板逐步过渡到底架地板9，将受力传递给底架地板，利用整体结构承载。 牵引梁6可根据受力情况，向枕内进行延伸，加强了力的传导。
上述所有结构的材质均为铝合金材料，此方案可适用头车二位端端部结构设计。
本实施例的轨道车辆无枕梁底架端部结构，其生产工艺如下：
第一步、将车钩安装座3、车钩支撑梁4和斜向支撑梁2焊接成形成主框架，车钩支撑梁4之间形成开口向前的65°夹角，斜向支撑梁2之间形成开口向后的130°夹角；
第二步、将车钩连接座5焊接于车钩安装座3后方，牵引梁6焊接于车钩连接座5的后方，形成了端部承载结构；
第三步、将底架端梁1、底架边梁7和底架地板9进行焊接，形成整体结构；
第四步、将所述端部承载结构与该整体结构焊接，具体的，将斜向支撑梁2的前端与底架端梁1焊接，车钩支撑梁4的外端与底架边梁7焊接，并且，端部承载结构与底架地板9的底面进行焊接，将前端连接板8的两端分别与斜向支撑梁2的前部外侧面和与底架边梁7内侧面焊接。
至此，完成整个无枕梁底架端部结构的组装。
除上述实施例外，本发明还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围。
