Description

一种中低速磁浮车辆及其悬浮架 技术领域
本发明涉及磁浮车辆技术领域，具体涉及一种中低速磁浮车辆及其悬浮架。
背景技术 
中低速磁浮车辆通常采用单独控制悬浮架两侧电磁铁模块悬浮间隙的控制方式。因此，为了避免两侧电磁铁悬浮间隙变化互相影响，要求悬浮架具备一定的解耦能力，使得两侧电磁铁垂向位移相对独立。
公开号为CN111483326A的中国发明专利申请公开了一种中低速磁浮列车小侧滚量悬浮架及磁浮列车，该悬浮架采用两组位于悬浮架两端的平行四边形防侧滚解耦结构进行解耦，其缺点在于：悬浮架结构连接零部件多且复杂，部件之间的公差通过叠加后容易产生累加误差，导致电磁铁内外侧极板产生相对偏差，不利于悬浮稳定。此外，由于防侧滚解耦结构位于悬浮架两端，同时设有空气弹簧，占用了较多的底架设备空间，不仅不利于底架设备布置，还增加了车辆成本。

 具体实施方式
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
各个附图中，“长度方向”、“宽度方向”、“高度方向”分别指磁浮车辆的长度方向、宽度方向、高度方向。
如图1、图2、图4、图8所示，一种磁浮车辆悬浮架，包括悬浮架本体10、托臂和滑台组件。悬浮架本体10包括两根纵梁1和一根横梁2，两根纵梁1和一根横梁2构成工字型构架。横梁2的两端分别与两根纵梁1的中部固定连接。纵梁1的底部安装有直线电机11。纵梁1底部可开设直线电机安装孔，直线电机11吊装在纵梁10下方。纵梁1平行于磁浮车辆的长度方向，横梁2平行于磁浮车辆的宽度方向。
托臂3位于纵梁1的两端，托臂3呈向悬浮架本体10内侧弯曲的C字型，托臂3的顶部与纵梁1固定连接，可固定在纵梁1端部。
如图1、图4、图5、图8、图9所示，滑台组件40设有两个，两个滑台组件40分别位于两根纵梁1上；滑台组件40包括滑台41、空气弹簧42和连接杆43，空气弹簧42的底部与纵梁1顶部的中部固定连接，空气弹簧42的顶部与滑台41的底部固定连接，滑台41通过连接杆43和铰接件44与悬浮架本体10铰接。连接杆43与铰接件44（作为连接杆43的安装座）铰接。连接杆43用于传递悬浮架与磁浮车辆车体7之间的牵引力。磁浮车辆车体7安装在滑台41上，悬浮架通过连接杆43拉动磁浮车辆车体7，使得磁浮车辆车体7与悬浮架一同前进。
如图1、图3、图4、图5、图6、图8、图9所示，每个纵梁1的下方各设有一悬浮组件50，悬浮组件50包括两块电磁铁极板51、连接板52和电磁铁线圈53，两块电磁铁极板51通过连接板52连接，电磁铁线圈53夹设于两块电磁铁极板51之间。电磁铁极板51的两端设有安装孔54，连接板52位于安装孔54的底部，即连接板52搭接在两块平行设置的电磁铁极板51的相应安装孔54上，可以提升连接板52的垂向支撑能力。安装孔内设有橡胶堆6，橡胶堆6的底部与连接板52的上表面连接，托臂3的底部插入安装孔54并与橡胶堆6的顶部连接。托臂3的底部可设置开孔，橡胶堆6的顶部和底部可设置安装件（例如定位螺柱、安装螺栓），橡胶堆6顶部的安装件可伸入托臂3底部的开孔中，从而使得托臂3底部与橡胶堆6顶部连接。橡胶堆6底部也可通过安装件安装在连接板52上。如图7所示为橡胶堆6的结构，橡胶堆6可采用层叠弹簧。电磁铁结构包括电磁铁极板51、电磁铁线圈53。电磁铁线圈53可绕设在铁芯上（图中未示出）。通电后铁芯两端产生磁场及磁力。电磁铁极板51的作用是引导将铁芯产生的横向磁场变成垂向磁场，产生对轨道的向上的吸力。此处，电磁铁线圈53也可称为电磁铁线包。本领域可以理解的是，仅设置电磁铁线圈53，不设置铁芯，也是可行的。
如图1、图4、图5、图8所示，在磁浮车辆的宽度方向上位于左侧的电磁铁极板51通过相应的柔性的橡胶堆6与宽度方向上位于左侧的托臂3连接，宽度方向上位于右侧的电磁铁极板51通过相应的柔性的橡胶堆6与宽度方向上位于右侧的托臂3连接。通过设置橡胶堆6，使得宽度方向上位于左侧和右侧的电磁铁模块可以在受到电磁力时，减少互相之间的干扰，从而实现电磁铁之间的解耦。
另外，由于橡胶堆6有垂向刚度，当悬浮架受到横向力（宽度方向上的力），产生倾覆力矩时，在宽度方向上位于左侧和右侧的两个橡胶堆6发生变形，产生反向力矩，防止悬浮架翻滚，从而实现防侧滚的功能。
如图1所示，为了降低车辆的重量，在纵梁的端部可设置两个并列设置的托臂3，两个托臂3之间通过连接梁连接。如果不考虑重量问题，也可利用一个托臂3代替两个并列设置的托臂3。
当电磁铁线圈53未通电时，由于重力作用，橡胶堆6在高度方向上处于向下拉伸状态；当电磁铁线圈53通电时，轨道9对电磁铁线圈53产生向上吸力，电磁铁线圈53有向上运动的趋势，使得电磁铁极板51也有向上运动的趋势，然而由于托臂3为刚性，托臂3下端对橡胶堆6产生向下的挤压，使得橡胶堆6处于压缩状态。
本发明还提供一种磁浮列车，如图8和图9所示，包括上述的磁浮车辆悬浮架以及磁浮车辆车体7，磁浮车辆车体7的底部沿磁浮车辆车体7的宽度方向设有滑轨8，滑轨8与滑台41滑动连接。通过设置滑轨8，悬浮架能够相对磁浮车辆车体7产生横向位移，使得车辆能够通过曲线线路。
如图10、图11所示，轨道9为磁浮车辆行进的轨道，可为F型轨道。两个F型轨道可设置在基座91上，两个F型轨道的延伸方向相互平行。当所述磁浮车辆位于轨道9上时，直线电机11、电磁铁结构分别位于轨道9的上方、下方。电磁铁线圈53通电后，电磁铁极板51对轨道9产生吸力，使得磁浮车辆悬浮。托臂3环抱轨道9设置，从而可以防止列车脱轨，提高车辆安全性。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
