The wheel subgrade is at a same distance with respect to the two permanent magnet subgrades, and the two permanent magnet subgrades are at a same distance with respect to and the respective walls of the U-shaped channel. In a flat road section, the wheel subgrade is flush with the permanent magnet subgrades; in an uphill or downhill road section, the wheel subgrade is higher than the permanent magnet subgrade. In case of running uphill or downhill or turning, the permanent magnets and electromagnets at the bottom of the vehicle are separated from the permanent magnet magnetic field on the permanent magnet subgrades, which facilitates uphill and downhill running, turning and stopping at the station.

In addition, all electrical equipment, including motors, electromagnetic coils, balancers, electric magnetic bases, etc., are automatically controlled by the control system, the circuit and control connection can be realized by conventional technology.

[0075] The working principle of the technical solution of this embodiment is as follows.

[0076] the present application utilizes the principle that permanent magnets with the same polarity repel each other, die vehicle is levitated by the repulsive force generated between the permanent magnet B located at the bottom of the carriage and the permanent magnet which has the same polarity with the permanent magnet B and is laid on the magnetic track at the bottom of the U-shaped channel groove; and the front and rear electric driving wheels of the vehicle rub the road surface to generate friction forces, which make the vehicle perform forward and backward movements. The electric driving device includes an electric driving wheel, front and rear support arms with spring damping, and a steering gear. The electric driving wheel is configured to perform forward and backward movements, steering, braking and energy recovery. The maglev vehicle running in the U-shaped channel can realize unmanned operation and 24-hour all-day operation.

[0077] In the U-shaped channel, the road surface of the wheel rail can be designed horizontally, uphill, downhill and turning by taken the on-site landform into consideration, the road surface of the wheel rail is designed in a lifted manner at uphill, downhill and turning locations, so that the maglev vehicle can be separated from the permanent magnet field of the magnetic track at the bottom of the U-shaped groove, the vehicle driving wheels on the road are used to support the weight of the vehicle carriage instead, which can realize the movements such as running uphill or downhill, steering of the vehicle; when the vehicle is in horizontal movement, the maglev vehicle runs to the designed horizontal magnetic track road surface, and a repulsive force is generated between the magnet at the bottom of the vehicle and the magnet on the magnetic track in the groove, to levitate the vehicle and make the maglev vehicle run horizontally.

[0078] The electromagnet mounted on the chassis can adjust the magnetic field intensity, so that the distance between the vehicle carriage and the permanent magnet of the magnetic track keeps stable for magnetic levitation; when the maglev vehicle enters a crowded area such as a station, the electromagnet can also make the permanent magnet at the bottom of the maglev vehicle lose magnetism, thus preventing the vehicle from adsorbing metallics such as iron in the station.

[0079] As the weight and number of maglev vehicles can be estimated, the load of the U-shaped channel can also be estimated, lightweight design may be adopted in the design of U-shaped channel, which can save unnecessary construction costs. Since the electric-driven maglev vehicle has no motor noise and impact sound generated by metal wheel rails, it can be set to pass through old residential areas and new residential areas, which is convenient for passengers to get on and off at the rails near their homes without leaving the community, and is also convenient for the weak and young people to go to the hospital or school, the passengers can directly get to the destination without stopping midway, which also avoids multiple accompanying personnel from going to special places.
