Description

动车组车体及其内风挡安装结构
本申请要求于2014年12月18日提交中国专利局、申请号为201410796477.5、发明名称为“动车组车体及其内风挡安装结构”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及轨道车辆技术领域，特别涉及一种动车组车体及其内风挡安装结构。
背景技术
动车组主要结构包括：牵引设备、转向架以及车体等部分，其中车体为列车的主要组成主体之一，车体既是旅客的乘坐载体，又是安装和连接其他几个组成部分(例如：走行部、制动装置、车端连接装置、车辆内部装饰设备等)的基础。
一般地，车体由司机室(头车、尾车)、底架、车顶、侧墙、端墙以及车体各附件组成，其中端墙一般设置于两节车厢之间，端墙的两侧连接车体的侧墙，端墙的顶部外缘连接车顶，端墙的底部对应设有缓冲梁，缓冲梁的底部对应设有车体底板。为了降低车辆外部噪音对车厢内环境的影响，在两节车厢之间还设置有风挡，风挡具体分为内风挡和外风挡。内风挡自车体端墙的顶部延伸至车体的端部底板处，故内风挡需与端墙、缓冲梁以及端部底板依次固定安装。
现有技术中内风挡与车体端部底板的安装方式为：在端部底板外侧相应位置设置安装座，然后采用焊接方式将内风挡的过渡板焊接于安装座上。该连接方式具有以下缺陷：
第一、内风挡的安装需要额外设置安装座，导致安装空间狭窄，且相应增加了整车重量；
第二、内风挡与安装座焊接连接时，因焊接热量影响，容易导致安装座位置受热不均匀，焊接后车体端部底板出现变形现象，增大了端部底板其他配合部件的装配误差；
第三、需要检修底板或是内风挡时，焊接固定的方式不利于检修的进行。
因此，如何改进现有技术中内风挡与端部底板的连接方式，以使该安装结构在实现安全稳定固定的同时，能够节省空间且便于内风挡与端部底板的快速拆装，是本领域内技术人员亟待解决的技术问题。

该方案，端部底板和内风挡过渡板通过底板螺栓和底板螺母即可实现固定安装。相较于背景技术具有下述技术效果：首先，通过底板螺栓固定内风挡和车体的端部底板，相较于焊接固定，该种连接方式可避免焊接变形，而且连接牢固，便于拆卸；其次，螺栓套筒作为安装座使用，且设于端部底板的型腔内，从而无需设置专门的安装座，既节省空间，也降低整车重量。再者，螺栓套筒设置于端部底板型腔内，可加强端部底板安装位置的强度，避免底板螺栓紧固时压紧端部底板而使其变形。

可选地，所述端墙螺母为异型螺母，包括大径端部和小径端部，所述端墙通孔包括相互连通的大孔部和小孔部，所述大径端部可穿过所述大孔部置于所述端部型腔中，并由所述大孔部滑动至所述小孔部后，由所述限位部件以及所述外侧板限位于所述端墙型腔内。
可选地，所述端墙螺母安装后，所述大径端部能够抵靠所述外侧板的内表面，所述小径端部的轴向长度小于或等于所述端墙通孔的长度。
可选地，所述限位部件包括设置于所述端墙型腔内部的限位筋，所述限位筋平行于所述端墙设置，并且所述限位筋与所述外侧板之间的距离等于或略大于所述大径端部的轴向长度。

具体实施方式
为了使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施例对本发明作进一步的详细说明。
请参考图1-2，图1为本发明所提供内风挡安装于车体端部一种具体实施例的结构示意图；图2为图1中内风挡安装于车体端部底板的结构示意图。
本实施例中的内风挡安装结构，用于安装内风挡40至车体的端部，具体是将内风挡的内风挡过渡板401安装至车体的端部。内风挡40的长度自车体端墙10的顶端延伸至车体的端部底板30位置，为实现内风挡40与端部底板可靠连接，本实施例中的内风挡40安装结构包括底板螺栓701、底板螺母703，以及螺栓套筒704。
如图2所示，螺栓套筒704贯穿并固定于车体的端部底板30，图2中车体的端部底板30为型材结构，螺栓套筒704处于端部底板30的型腔中。安装时，底板螺栓701可自上向下插入螺栓套筒704，以依次贯穿内风挡过渡板401和端部底板30，然后底板螺栓701的外螺纹段与位于端部底板30底部的底板螺母703配合实现锁紧。
该方案相较于背景技术具有下述技术效果：
首先，通过底板螺栓701固定内风挡40和车体的端部底板30，相较于焊接固定，该种连接方式可避免焊接变形，而且连接牢固，便于拆卸；
其次，螺栓套筒704作为安装座使用，且设于端部底板30的型腔内，从而无需设置专门的安装座，既节省空间，也降低整车重量。
再者，螺栓套筒704设置于端部底板30型腔内，可加强端部底板30 安装位置的强度，避免底板螺栓701紧固时压紧端部底板30而使其变形。
具体地，螺栓套筒704的两端可以与端部底板30的内外表面平齐，如图2所示。可以在端部底板30冲压通孔，将与通孔长度、孔径均相当的螺栓套筒704插入该通孔中，然后焊接固定，当然也可以通过其他方式实现固定，比如粘结、压装。如此设置，使得底板螺栓701的头部以及内风挡过渡板401可以较好地贴合于端部底板30，加强连接紧密性。
另外，为便于底板螺栓701的插入，螺栓套筒704的内径可以大于底板螺栓701的外径。底板螺母703和端部底板30之间可以设有垫片702，此时，基于螺栓套筒704的大内径，该垫片702为特制的大垫片。垫片702可提高底板螺栓701与端部底板30的紧密性，也避免底板螺栓701在锁紧过程中损伤端部底板30的外侧面。
作为进一步的改进，还请参考图3，图3为图1中内风挡安装于车体缓冲梁处的结构示意图。
本实施例提供的内风挡安装结构还包括梁体螺栓601和固定于车体缓冲梁20的梁体螺母602。图3中，梁体螺母602为T形螺母，T形螺母的侧翼通过紧固螺栓603固定于车体缓冲梁20，可以理解，选取普通结构的梁体螺母602也是可行的，此时可通过粘结、焊接等方式实现梁体螺母602的固定，当然，T形螺母和紧固螺栓603的固定方式易于实现且不会产生变形。梁体螺栓601自内风挡过渡板401外侧贯穿内风挡过渡板401和缓冲梁20，贯穿后自动与梁体螺母602配合锁紧。需要说明的是，全文所述的内侧为靠近车体内部的方向，远离车体内部的方向为外侧。图3中即图1中内风挡40左侧部分与缓冲梁20安装的示意图，右侧部分可对照理解。
同样，现有技术中也是通过设置专门的安装座实现缓冲梁20和内风挡40的焊接固定，而本实施例具体通过梁体螺栓601固定内风挡40和车体的缓冲梁20，相较于焊接固定，该种连接方式可避免焊接变形，而且连接牢固。另外，梁体螺母602与缓冲梁20固定，则插入梁体螺栓601时，无需把持梁体螺母602，直接插入并旋紧梁体螺栓601即可，能够实现快速拆装，且满足缓冲梁20区域的安装空间要求。
进一步地，请参考图4、图5和图7，图4为图1中内风挡安装于车体 端墙的结构示意图；图5为图4中设有端墙螺母的端墙型腔示意图；图7为图1中端墙的正视示意图。图4中示出图1中内风挡40左侧部分与端墙10安装的示意图，内风挡40右侧部分以及上侧部分可参照理解。
内风挡10具有内侧板102和外侧板101，二者之间具有加强筋104，加强筋104、内侧板102、外侧板101之间形成端墙型腔105。该具体实施例中的内风挡40安装结构还进一步包括设于端墙10的端墙型腔105中的端墙螺母501以及与之配合的端墙螺栓502，还包括将端墙螺母501限位于装配位置的限位部件，限位部件也设置于端墙型腔105内部，并且端墙10的墙体上还设置有与端墙螺母501内螺纹孔位置相对应的端墙通孔106。
相应地，内风挡过渡板401设置有与端墙通孔106相对应的过渡板通孔，端墙螺栓502的外螺纹段穿过过渡板通孔和端墙通孔106后与端墙螺母501的内螺纹孔旋紧。
可以理解，端墙通孔106和过渡板通孔只要能够供端墙螺栓502的外螺纹段贯穿即可，对孔体形状、是否有螺纹并不作限制。
本实施例在端墙型腔105内部设置端墙螺母501，并且限定端墙螺母501位置的限位部件也设置于端墙型腔105中，固定内风挡过渡板401和端墙10时，可以直接使用端墙螺栓502，端墙螺栓502的外螺纹段穿过内风挡过渡板401和端墙10后与端墙10配合锁紧，从而将内风挡40固定于端墙10。
同样，现有技术中也是采用专门外设安装座的方式实现端墙10和内风挡40的焊接固定。本实施例的安装方式无需在端墙10的墙体外部设置额外的安装座，可节省空间，减轻重量，且使用端墙螺栓502和端墙螺母501配合安装，安装可靠，并避免焊接安装座时对端墙10的墙体的影响，防止变形，提高了端墙10与车体其他配合部件的装配精度；另外，端墙螺母501和端墙螺栓502的螺纹安装方式有利于内风挡40与端墙10的拆卸，便于后期维护更换。
此外，内风挡40安装结构主要设置于端墙型腔105内部，无需占据端墙10外部空间，在一定程度上提高了内风挡40安装固定后的美观性。
请参考图5-8，图5为图4中设有端墙螺母的端墙型腔示意图；图6 为图4中端墙螺母的结构示意图；图8为图7中端墙通孔的示意图。
在一种具体的实施方式中，端墙螺母501可采用异型螺母，包括大径端部501a和小径端部501b，端墙通孔106包括相互连通的大孔部a1和小孔部a2，且小孔部a2具有与小径端部501b的外表面相配合的内轮廓，以端墙螺母501的小径端部501b的外表面的横截面为圆形为例，小孔部a2与小径端部501b配合位置的内轮廓为半圆形，如图所述的小孔部a2底端。安装时，可将端墙螺母501大径端部501a沿垂直纸面方向穿过大孔部a1置于端墙型腔105中，再向下滑动至小孔部a2，小孔部a2支撑端墙螺母501的小径端部501b，则端墙螺母501限位于限位部件和端墙10的外侧板101之间。
其中，图8中给出了一种大孔部a1和小孔部a2具体结构的示意图，大孔部a1为方形，小孔部a2为半长圆形，其中通孔尺寸可以根据端墙螺母501的尺寸而定，倒角尺寸可以根据加工工艺而设定。
端墙螺母501安装后，大径端部501a的端面抵靠端墙10的外侧板101，小径端部501b的轴向长度小于或等于端墙通孔106的深度；在实现可靠固定的情况下，小径端部501b尽量不占据墙体外部的空间，以使内风挡过渡板401能够与端墙10贴合。
请再次参考图5，上述各实施例中，限位部件可以包括设置于端墙型腔101内部的限位筋103，限位筋103平行于端墙10的墙体，并且限位筋103与开设端墙通孔106的端墙外侧板101之间的距离等于或略大于大径端部501a的轴向长度，以满足限位需求，确保端墙螺母501不会掉落至端墙型腔105中即可。
固定内风挡过渡板401和端墙10时，异型螺母抵靠限位筋103，端墙螺栓502的外螺纹段旋入端墙螺母501的内螺纹孔。
该实施方式中限位筋103可以与墙体一体挤压成型，也可以通过其他方式安装于端墙型腔105中；上述实施方式中限位筋103结构比较简单，成型工艺简单，巧妙地实现了端墙螺母501的限位。
图5中，限位筋103的数量可以为两个，两限位筋103相对设置，分别置于端墙螺母501大径端部501a外端面的两侧。这样，端墙螺母501 在端墙10的外侧板101、两限位筋103的作用下，可实现可靠支撑限位。
可以理解，最为优选的方案是，整个内风挡40自上之下，分别由设置于端墙型腔105内的端墙螺母501固定于端墙10、由梁体螺栓601固定于缓冲梁20、由底板螺栓701固定于端部底板30，以使内风挡40的各段安装均无需设置专门的安装座，无需焊接，并与各段所对应的操作空间相适应，且拆装方便。
