具体实施方式
为了使本申请实施例中的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
实施例一
图1为本申请实施例的用于磁悬浮车辆的底架的示意图；图2为图1所示的底架的地板组成的示意图；图3为图2所示的地板组成的爆炸图。
如图1，图2和图3所示，本申请实施例的用于磁悬浮车辆的底架，包括地板组成100，多个滑台200和牵引缓冲装置300。
所述地板组成100包括：
地板骨架110，所述地板骨架110是复合材料的地板骨架；
上面板120，固定于所述地板骨架110的上表面，所述上面板120是复合材料的上面板；
下面板130，固定于所述地板骨架110的下表面，所述下面板130是复合材料的下面板；

本申请实施例的磁悬浮车辆的底架，地板组成中的地板骨架，上面板和下面板都是复合材料的，上面板固定于地板骨架的上表面，下面板固定于地板骨架的下表面，这样就形成了地板组成。这样，地板组成是整体是复合材料的，在强度和刚度达到地板组成的要求的情况下，整体的重量较小，适合磁悬浮车辆要求整体重量较小的要求；滑台中起支撑作用的直接结构是复合材料的，滑台通过支撑结构固定于所述地板组成的上表面之上，滑台用于连接轨道车辆的悬浮架，滑台强度能够足够支撑悬浮架，同时，重量较小，结构简单，对车下空间占用较小，能够适用于磁悬浮车辆。因此，本申请实施例的底架，底架整体的重量较小，适合磁悬浮车辆要求整体重量较小的要求。
下面对地板组成的结构进行说明。
图4为图3所示的地板组成的地板骨架的示意图。实施中，如图3所示，所述地板骨架110围成的内部空间填充复合材料形成填充层140并在所述填充层140内预埋结构件；
所述上面板120，所述下面板130，所述地板骨架110和所述填充层140采用共固化工艺形成。
地板骨架本身是框架结构，地板骨架围成的内部空间填充复合材料形成填充层，为了实现与磁悬浮车辆其他部件的连接，需要在填充层内预埋结构件，这样预埋的结构件用于与磁悬浮车辆的其他部件连接。
实施中，所述地板骨架是碳纤维材料的地板骨架，所述上面板是是碳纤维材料的上面板，所述下面板是碳纤维材料的下面板；
所述填充层是聚甲基丙烯酰亚胺材料形成的泡沫形成的填充层。
地板骨架，上面板和下面板是碳纤维材料的，填充层是聚甲基丙烯酰亚胺材料形成的泡沫，聚甲基丙烯酰亚胺材料是硬质泡沫塑料，形成的泡沫硬度较大，且密度较小。聚甲基丙烯酰亚胺材料形成的泡沫的密度小于碳纤维材料，有利于控制地板组成的整体的重量，同时控制了地板组成的总成本。
实施中，如图2和图3所示，所述地板组成100是所述磁悬浮车辆的司机 室和与所述司机室连接的端车的地板组成。
这样，司机室和与司机室连接的端车的地板组成是一个整体，组装成磁悬浮车辆时，组装较为便捷。
进一步的，下面对地板组成的地板骨架的结构进行说明。
实施中，如图4所示，所述地板骨架包括：

尾部端梁112-2，所述尾部端梁112-2为条状，固定在两个所述边梁111的尾端；
所述边梁111，所述头部端梁112-1和所述尾部端梁112-2围成封闭的形状，以增强所述地板骨架的强度。
这样，地板骨架是一个封闭的形状，这样封闭形状的地板骨架在受力后不易发生形变，地板骨架的结构较为稳定。
实施中，如图4所示，地板组成还包括：
两个纵梁113，两个所述纵梁113平行设置在两个所述边梁111之间，且将两个所述边梁111之间的间隔平均分为三个空间；
所述纵梁113的两端分别固定在所述头部端梁112-1的上底内侧和所述尾部端梁112-2的内侧。
这样，两个纵梁将地板骨架的外边缘围成的整个的空间分成了三个小空间，使得地板骨架的结构更加稳固。
实施中，如图4所示，所述边梁111在对应于所述磁悬浮车辆的安装车门的位置具有向内凸起对边梁进行补强。
所述磁悬浮车辆的安装车门的位置，需要在车体上开口，对地板组成此位置的强度的要求变高，因此，需要在地板组成对应的位置，进行补强，因此， 在边梁的内侧具有内凸的凸起。凸起的形状与磁悬浮车辆的车门处相关，相配合。
实施中，如图4所示，地板组成还包括：
多组的门位置补强横梁114-1，各组所述门位置补强横梁114-1间隔设置在所述边梁的凸起之间；

实施中，如图4所示，地板组成还包括：
多组的正常位置横梁114-3，各组所述正常位置横梁114-3间隔设置在所述地板组成需要补强的位置；

在磁悬浮车辆的车门和滑台结构对应的位置以外的位置，需要补强的，通过设置多组的正常位置横梁实现。
这样，通过多组的门位置补强横梁，多组的滑台位置补强横梁和多组的正常位置横梁将边梁和纵梁之间的空间，两个纵梁之间的空间划分为多个更小的空间，从而使得地板组成的结构更加稳固。

下面对滑台的结构进行说明。
图11为图1所示的底架的滑台的示意图；图12为图11所示的用于磁悬浮车辆的滑台的爆炸图。
如图11和图12所示，所述滑台200用于连接磁悬浮车辆的悬浮架，包括复合材料的支撑结构210，所述支撑结构210包括：

所述加强筋250固定在同侧的所述固定下边沿211-1和所述固定上翻边230之间。
加强筋固定在同侧的固定下边沿和固定上翻边之间，大大增强了固定下边沿和固定上翻边之间的强度和刚度，从而增强了滑台的强度和刚度。同时，固 定上翻边，加强筋和固定下边沿都是复合材料的，存在一定的弹性形变的空间，因此在传递悬浮架的力的作用是柔性的传递，使得使用本申请实施例的滑台的磁悬浮列车的舒适性较高。
实施中，如图11，图12，图17和图18所示，所述加强筋250是截面为槽型的加强筋250，所述加强筋的两侧槽壁分别固定与同侧的所述固定上翻边和固定下边沿固定；
其中，同侧的所述固定上翻边和固定下边沿之间间隔固定有四个所述加强筋。

实施中，如图12和图14所示，所述固定上翻边230高于所述支撑主体220的上表面，所述支撑主体的上表面之上到所述固定上翻边之间的空间形成避让空间；
其中，所述避让空间用于避让所述磁悬浮车辆的悬浮架。
固定上翻边是高于支撑主体的上表面的，从而在支撑主体的上表面之上到固定上翻边之间形成用于避让悬浮架的空间，与悬浮架的结构相配合，便于实现与悬浮架的连接。
实施中，如图16所示，所述支撑主体的第一侧的下部具有内凹的凹口222；
其中，所述支撑主体的第一侧是与所述固定下边沿相交，且在所述滑台固定于所述磁悬浮车辆的底架之上后朝向所述底架内的一侧。
凹口的存在，一方面使得支撑主体在受到自上而下的力的作用时，存在一定的弹性形变的空间，因此在传递悬浮架的力的作用是柔性的传递；另一方面，凹口也能作为避让磁悬浮车辆其他部件的空间。
图19为图12所示的滑台的遮盖罩的示意图。实施中，如图11，图12和图19所示，滑台还包括遮盖罩260；
所述遮盖罩260安装在所述支撑结构的第二侧，从所述支撑结构的第二侧 遮盖住所述支撑结构；
其中，所述支撑结构的第二侧与所述支撑主体的第一侧位置相对。
在滑台与磁悬浮车辆的底架固定后，支撑结构的第二侧是朝向磁悬浮车辆的底架的外侧的，是会被人看到的方向，因此设置遮盖罩进行遮盖。
实施中，所述支撑结构是整体成型的一体化结构的支撑结构。
支撑结构是整个滑台结构的主体，起到支撑整个悬浮架的作用，整体成型的支撑结构，使得支撑结构的整体性好，刚度和强度较高。
实施中，所述耐磨条是铝合金材料的耐磨条；
所述支撑结构是碳纤维材料的支撑结构，所述加强筋是碳纤维材料的加强筋。
支撑结构和加强筋都是碳纤维材料的，重量较小，使得滑台整体的重量较小，适应磁悬浮车辆轻量化发展的趋势；耐磨条采用铝合金材料的耐磨条，使得耐磨条的耐磨性较好。

本申请实施例的磁悬浮车辆的牵引缓冲装置，刚性的耐磨板固定在牵引缓冲本体的前端面，耐磨板用于与磁悬浮车辆的车钩连接，牵引缓冲本体的底端用于与磁悬浮车辆的底架连接，这样，牵引缓冲装置能够实现对车钩的牵引力 传递和对冲击力的缓冲。牵引缓冲本体由于采用的是复合材料，复合材料的密度较小，使得整个牵引缓冲装置的重量较小；复合材料的牵引缓冲装置的制造过程中不需要焊接，制造工艺也较为简单。本申请实施例的牵引缓冲装置，由于采用了复合材料的牵引缓冲本体，牵引缓冲装置的重量较小，制造较为简单。
图24为图20所示的牵引缓冲装置的牵引缓冲本体的主视放大图；图25为图24所示的牵引缓冲本体的B-B剖面图；图26为图24所示的牵引缓冲本体的C-C剖视图。实施中，如图24，图25和图26所示，所述牵引缓冲本体310包括：
固定板320，所述固定板320是碳纤维材料的固定板320，所述固定板320用于与所述磁悬浮车辆的底架连接；

泡沫332，填充固定在所述框形外壳331的“几”字形结构的空腔内。
泡沫的密度比碳纤维材料的密度小，这样，在保证牵引缓冲框强度的前提下，牵引缓冲框的重量较小，成本也较低；所述框形外壳下端外翻的翻边使得与固定板的固定面较大，牵引缓冲框与固定板的固定更为稳固。
实施中，所述牵引缓冲本体是整体成型的一体化结构。
这样，牵引缓冲本体本身不是多个部件通过连接件固定连接在一起的，而是整体成型的一体化结构，牵引缓冲本体的结构更为坚固。牵引缓冲本体由于采用的是复合材料，复合材料的密度较小，使得整个牵引缓冲装置的重量较小，复合材料的牵引缓冲装置的制造过程中不需要焊接，制造工艺也较为简单。
实施中，所述框形外壳的“几”字形结构的单层厚度是12毫米，所述固定板的厚度是6毫米；
所述泡沫是聚甲基丙烯酰亚胺材料形成的泡沫，聚甲基丙烯酰亚胺的英文简称是PMI，应为全称是Polymethacrylimide。

实施中，如图20，图22和图23所示，固化为一体的所述框形外壳下端外翻的框形外壳翻边331-1和所述固定板具有贯穿的螺栓孔；
所述螺栓孔用于配合螺栓将所述牵引缓冲装置固定于所述磁悬浮车辆的底架之上，且所述固定板320和所述磁悬浮车辆的底架也通过胶接固定。
这样，能够将牵引缓冲装置固定于所述磁悬浮车辆的底架之上，固定牢固，传递牵引力。
实施中，如图20所示，所述框形外壳的后框和两个侧框板开有走线孔350；
所述框形外壳的后框设置有两个所述走线孔350，所述框形外壳的每个侧框板设置有一个所述走线孔350。

具体的，所述耐磨板为6毫米厚的铝板，通过胶接及螺接固定在所述牵引缓冲本体的前端面。
这样，耐磨板和牵引缓冲本体的固定十分稳固，耐磨板的耐磨性也较高。
具体的，由于牵引缓冲装置的牵引缓冲本体是复合材料的，复合材料的牵引缓冲本体制造是不同于背景技术中的焊接的，牵引缓冲本体的制造工艺相对简单。
实施中，如图1所示，底架还包括：
试验装置400，所述试验装置400设置于所述头部端梁112-1朝向车头方向一端，采用栓接连接和铆接的方式和地板组成相连；
