Abstract

A permanent magnetic and superconducting suspension vehicle is provided at intervals with permanent magnetic railway tracks in the path length direction, or is provided continuously with the permanent magnetic railway tracks, while the thickness of a permanent magnet is thinned so as to reduce the consumption of railway track permanent magnetic materials; moreover, a bottom surface of a vehicle bottom opposite to the railway track is provided with a superconducting magnet which has much stronger magnetic force than the prior permanent magnet; therefore, by means of the magnetic repulsion between magnetic poles of the same polarity of the permanent magnet on the railway track and the superconducting magnet on the vehicle bottom, vehicle body suspension and guiding can be realized; in addition, a vehicle is propelled by means of the interaction between a magnet wheel or an electric coil and the railway track, or a turbofan and a turbine air jet device are arranged on the vehicle as an engine. The permanent magnetic and superconducting suspension vehicle can substantially reduce the cost of a magnetic suspension transportation system, and is of greater significance to the popularization and the application of the magnetic suspension transportation system.

Description

technical field [0001] The invention relates to a magnetic levitation vehicle, in particular to a permanent magnet and superconducting levitation vehicle. Background technique [0002] Magnetic levitation vehicles have excellent performances such as non-contact, low vibration, low noise, safety, speed, and high efficiency. The maglev train technology in Japan and Germany is at the forefront, especially the maglev train in Germany has been extended to commercial operation. According to the levitation mode, the maglev vehicles are divided into suction-floating type and repelling-floating type. Germany adopts the constant conduction suction floating type, while Japan adopts the superconducting repellent floating type. The so-called constant guiding suction floating type is to use the electromagnet set on the train to attract the magnetic track set under the roadbed, so that the train is suspended and guided, and it is propelled by a synchronous or asynchronous linear motor. T...
