Description

一种适用于鼓形车体的轨道车辆底架边梁连接结构 技术领域
本发明涉及轨道车辆的底架边梁，特别是适用于鼓形车体的轨道车辆。
 背景技术
多年来我国的常规铁路客车一直为直车体，采用碳钢材质的板梁结构。底架边梁通常采用18b热轧槽钢，车下设备安装采用横梁吊挂。设有裙板的车辆，需要在底架上加焊纵梁和安装座。随着高速车的快速发展，对车辆的气动性能和舒适性的要求越来越高，中高速客车采用直车体逐步减少，鼓形车体成为主流，车下设备安装方式和裙板的安装方式发生了变化，原结构不能满足要求。
现有铁路客底架边梁多采用槽钢18b-Q235B，两边梁间布有多根横梁，枕内横梁两端比中间高30mm,用于铺放厚度为30mm的波纹地板，横梁插在边梁槽内焊接，加工难度大，组装难度高。枕外横梁比枕内横梁高30mm，重量增大，上面铺放平地板。枕内波纹地板和枕外平地铁均搭接在边梁上翼面外侧满焊，波纹地板下面与边梁段焊。车下设备安装采用横梁吊挂，吊座焊在横梁上。底架边梁焊有多个安装座，用于安装裙板。边梁外侧面上端刨槽，侧墙板与之搭接焊后磨平，提高了侧墙的平面度。侧墙立柱下端与边梁上翼面外侧焊接，立柱为帽型或乙型，断面高度尺寸为70mm,下端开有止口以避开与地板干涉，增加了立柱加工工作量；立柱下端与地板焊接，焊缝附近的立柱和地板的疲劳应力增加。
该种槽钢形式的底架边梁只适用于直车体，槽钢高度尺寸较小，不适用于边梁吊挂，车下设备安装复杂；横梁断面为变截面，加工难度和组装难度大；枕外横梁断面大，枕内横梁靠边梁侧断面大，重量较重，不利于车体轻量化。立柱下端开止口，增加了加工量；立柱下端与地板焊接，焊缝附近的立柱和地板的疲劳应力增加。
经检索发现中国实用新型CN 207481901 U公开了一种车体底架边梁，该边梁为折弯件，将边梁与门槛冷弯成型为一体结构。代替现有技术中边梁与门槛通过焊接固定，提高边梁的整体垂向刚度和强度。该底架边梁仅适用于有门槛的底架，没有与侧墙的接口。
 技术问题
本发明的目的主要是针对上述现有技术中的问题，提供一种适用于鼓形车体的轨道车辆底架边梁连接结构，实现了车下设备边梁吊挂的方式。解决了侧墙立柱与地板连接处疲劳应力较大的问题；降低了横梁加工难度和组装难度；减轻了车体的重量。
 技术解决方案
为了解决以上技术问题，本发明提供的适用于鼓形车体的轨道车辆底架边梁连接结构，包含底架边梁、底架横梁、侧墙立柱、侧墙板和车下设备吊座，其特征在于：所述底架边梁为辊弯件，其断面为槽型结构，具有侧面、上翼面和下翼面，该侧面具有与侧墙板一致的倾斜角度，所述侧面的外侧上端设有内凹的压台，侧墙板搭接在该压台上对焊焊接固定；所述下翼面的内端设有向下竖直翻边，一立板焊接固定于上翼面和下翼面之间，立板的内侧面与竖直翻边的内侧面共面，作为车下设备吊座的安装面；底架横梁的上平面与底架边梁的上翼面平齐，底架横梁的两端与底架边梁的侧面的内表面焊接固定。
本发明还公开一种鼓形车体的轨道车辆底架结构，其特征在于：具有上述述的适用于鼓形车体的轨道车辆底架边梁连接结构。
此外，本发明还要求保护一种轨道车辆，其特征在于：具有上述的适用于鼓形车体的轨道车辆底架边梁连接结构。
 有益效果
本发明有益效果如下：本发明提供了一种适用于鼓形断面钢制车体底架的边梁及其与周边零部件的连接结构；实现了车下设备边梁吊挂的安装方式；提高了侧墙平面度；降低了侧墙立柱与地板连接处疲劳应力；提供了一种简单的侧裙板安装结构。本发明可为160km/h及以上的铁路客车或动车组鼓型钢制车体提供参考或借鉴。
