具体实施方式
下面通过实施例并结合附图对本发明做进一步说明，但不限于此。
实施例1：
如图1-2所示，本实施例提供一种轮轨式磁悬浮车辆系统，包括U型通道及置于U 型通道内的磁悬浮车；
U型通道的底部设置有两条永磁体路基(左侧永磁体路基8和右侧永磁体路基22)和一条车轮路基20，两条永磁体路基位于车轮路基20的两侧，两条永磁体路基上铺设有永磁体A(左侧永磁体A7和右侧永磁体A21)；
磁悬浮车包括厢体、底盘、前驱动轮4和后驱动轮，前驱动轮4和后驱动轮分别连接在厢体的前后两侧，厢体安装在底盘上，底盘两侧设置有永磁体B(左侧永磁体B6和右侧永磁体B19)，永磁体B与永磁体A上下对应且极性相同，前驱动轮和后驱动轮置于车轮路基20上；
U型通道顶部两侧设置有供电线排(左供电线排2和右供电线排15)，厢体两侧设置有拾电电缆(左拾电电缆1和右拾电电缆14)，拾电电缆与供电线排接触，为磁悬浮车提供电力。
具体地，前驱动轮和后驱动轮均为电驱轮，二者的结构完全相同。电驱轮包括电机、车轮29、弹性叉臂31、安装板以及电动转向机构；电机设置在车轮中心且与车轮固连，电机输出轴的两端连接弹性叉臂31，安装板24一侧与厢体固定连接，电动转向机构23设置在安装板24上并与弹性叉臂31顶端连接。
电机选用外转子电机，电机的外壳与车轮25通过键连接。当电机通电启动后，电机外壳及电磁线圈为转子，带动车轮25一起旋转，电机的输出轴为定子。电动转向机构采用常规技术，将转向电机使用螺栓安装在安装板24上，转向电机的输出轴通过轴承穿过安装板24的丝扣孔后与弹性叉臂31连接。
底盘上还设置有电磁体，电磁体主要由电磁线圈32组成，通过给电磁线圈32通电，实现电磁体产生磁性。当车辆行驶过程中，出现前后左右不平衡时，利用电磁线圈32产生的磁场对车辆进行纠正。
如图4和图5所示，底盘上还设置有电动磁力座，底盘的左右两侧分别设置左电动磁力座和右电动磁力座。电动磁力座包括电机、旋转轴和永磁体C，电机的输出轴连接旋转轴，旋转轴上设置有至少一个永磁体C。通过电机调节永磁体C的极性方向，工作状态下，永磁体C呈竖直状态，永磁体C与永磁体A产生相斥力，未工作状态下，永磁体C呈水平状态，永磁体C与永磁体A之间无相斥力，电动磁力座起到调节磁场的作用。
永磁体B对磁轨上的永磁体A产生的反斥力使车辆悬浮并满足基本载荷，当车辆乘客增加出现超载时，电动磁力座启动，永磁体C对永磁体A产生反斥力，使车辆车厢与 永磁体A保持设计间隙，不至于出现车厢忽高忽低无法控制车辆的情况。
厢体内设置有蓄电池3和控制系统17。通过厢体内的控制系统，可以控制电机的运行状态，从而控制磁悬浮车的前进、停止、加速、减速，同时通过磁悬浮车在运行过程中边走边充电，多余的电量可存储在蓄电池内，当外部电源不能工作时，可通过蓄电池供电，不影响磁悬浮车的运行。
厢体内部的前后两侧设置有左右平衡器12，左右平衡器包括驱动电机41、基座、丝杆42和配重滑块43；丝杆42设置在基座上，丝杆42一端与驱动电机41的输出轴连接，配重滑块43螺丝连接在丝杆42上。在车厢内人员数量不均等时，可对车厢进行再平衡。
厢体内部的左右两侧设置有前后平衡器13，前后平衡器包括驱动电机44、基座、丝杆45和配重滑块46；丝杆45设置在基座上，丝杆45一端与驱动电机44的输出轴连接，配重滑块46螺丝连接在丝杆45上。不论是左右平衡器12还是前后平衡器13，都可在车辆运行前进行调整，保证车辆运行过程中的稳定性。
厢体的两侧设置有电动车厢门26，电动车厢门连接控制系统。此设计的好处是，在厢体两侧设置电动车厢门，方便乘客上下车。
U型通道内，厢体至少有1/3部分位于U型通道内，保证厢体运行过程中的稳定性。车轮路基与两条永磁体路基的距离相等，两条永磁体路基距离U型通道壁的距离相等。平地路况段，车轮路基与永磁体路基水平；上坡或下坡路况段，车轮路基高于永磁体路基。在上坡或下坡路段或转弯时，使车辆底部永磁体与电磁体脱离永磁体路基上的永磁体磁场，方便车辆进行爬坡、下坡、转弯、靠进站。
厢体的前后两侧设置有限位臂。限位臂可防止车辆相互追尾，也可使得磁悬浮车辆如有个别磁悬浮车辆出现故障无法前进时利用前后端的磁悬浮车辆将其推至站点维修。
控制系统包括PLC和无线通信模块，通过无线通信模块可与调度中心进行数据传输。车辆自动控制系统可通过车辆定位、5G实时数据上传下载，利用大数据对每台在轨车辆实施精确控制，对驱动轮实施减速加速转向刹车等动作，使车辆达到最佳运行。
厢体内设置有软硬座，方便不同的使用需求。厢体内设置有空调及空气净化系统，用于净化厢体内的舒适度，提升乘坐舒适性。厢体内外安装有照明系统，厢体内设有方便乘客阅读的阅读灯，厢体外设有彩色显示灯，夜间行驶尤其是进站时，起到警示作用。
控制系统内装有自动驾驶程序，可以实现车辆的自动运行，另外，所有用电设备，包括电机、电磁线圈、平衡器、电动磁力座等都由控制系统实现自动控制，电路及控制 连接关系采用常规技术可实现。
本实施例技术方案工作原理：
本发明是利用永磁体同极磁体相互排斥原理，利用车辆厢体底部永磁体B与U型通道槽底铺设在磁轨上的同极永磁体产生相斥力使车辆悬浮，利用车辆前后着地电动驱动轮摩擦路面产生摩擦力使车辆做前后运动，电动驱动装置包括：电动驱动轮、弹簧减震前后叉臂、转向器，电动驱动轮具有前后运动、转向、刹车、能量回收功能。在U型通道内运行的磁悬浮车辆可以实现无人驾驶运行，也可以实现24小时全天运行。
U型槽通道内，轮轨路面结合现场地貌可做水平、爬坡、下坡、转弯设计，在爬坡、下坡、转弯处设计轮轨路面抬升，使得磁悬浮车辆脱离U型槽底部磁轨永磁体磁场，改由路面上的车辆驱动轮支撑车辆箱体重量，可实现车辆爬坡、下坡、转向等动作，待车辆处于水平运动时，让磁悬浮车辆运行至设计好的水平磁轨路面，此时车辆底部磁体与槽内磁轨上的磁体产生相斥力达到车辆悬浮目的，并使得磁悬浮车辆做水平方向运行。
安装在底盘上的电磁体可调节磁场强度，使得车辆厢体与磁轨永磁体之间距离保持稳定的磁悬浮间距，电磁体也可让磁悬浮车辆进入车站内等人员密集区域时让磁悬浮车辆底部的永磁体失去磁性，避免车辆在车站内吸附铁质等金属物质。
由于磁悬浮车辆重量和数量可以预计，使得U型通道载荷可以预计，在设计U型通道时可采用轻量化设计，为工程造价节省不必要的额外成本，由于电动驱动磁悬浮车辆没有马达噪音及金属轮轨产生的撞击声。可方便地设置在穿行通过老旧小区和新区，让乘客不出小区在家门口轨道上下车，方便乘客出行，也可方便体弱、年幼人员去医院或学校，一站直达，避免多名陪护人员去特殊场所。

弹簧液压支撑导向轮16的具体结构如图8所示，每一个弹簧液压支撑导向轮16都包括液压支撑固定座1603、液压缸1605、弹簧1602、导向轮轴1604和滚轮1601，其中液压缸1605的缸筒固定在液压支撑固定座1603上，液压支撑固定座1603通过螺栓1606安装在厢体侧壁上，液压缸1605的活塞杆上套装弹簧1602，活塞杆的头部与导向轮轴1604固连，导向轮轴1604与滚轮1601中心通过键连接。
