Meanwhile, on the basis of the existing magnetic suspension system, the transportation system can realize miniaturization design, and if the transportation system is applied to simplification of a scenic region control system and the like, the miniaturization system can further reduce vehicle load and structure, so that the transportation system has stronger line and engineering applicability, is particularly suitable for being popularized in scenic regions with complex line environments and higher investment cost control requirements, and can also be used as a supplementary role of the existing urban rail transit transportation system to further perfect the urban transportation system.

The utility model provides a transport system provides the train of even hanging unpowered a plurality of magnetic suspension intermediate cars and forming by the end car that the wheel was pull, and perfect combination wheeled vehicle and magnetic levitation vehicle's a great deal of advantage, all carriages all adopt carriage and bogie one to one or a pair of many the mode of arranging. The train adopts half suspension mode (the end car adopts the wheel to support, and the suspension mode is all adopted in middle part carriage), and the riding comfort of passenger has greatly been improved in the middle carriage of suspension state. Meanwhile, the power of the train is from the end vehicles, and the two end vehicles are redundant with each other, so that the stability of system operation is further ensured, and the railway transportation system is a brand-new railway transportation product.

The utility model provides a transportation system can miniaturize and simplify the design on current magnetic levitation system basis, all carries out reducing of structure size and the optimization of system to each side such as vehicle, track, bridge and circuit. The optimized system has smaller structural load and structural size, is suitable for various complicated and large-investment systems such as a signal system, a power supply system, a station room and the like under the simple road network environment such as scenic spots and the like, and can greatly reduce the system investment. In addition, the vehicle adopts an independent multi-carriage coupling mode, the marshalling is flexible, the turning radius is further reduced, and the line adaptability is stronger, so that the product popularization and market competitiveness are stronger.
