Abstract

The invention relates to a maglev electric vehicle, which is characterized in that: a coil or a combined electric conductor and a plurality of vehicle body permanent magnet plates with the same peripheral polarity are arranged on the vehicle bottom plate, and the coil, or the combined electric conductor and the vehicle body permanent magnet plates shun each other along the lengthwise direction of the vehicle; a rail fixed on a road foundation is arranged right below the coil, the electric conductor as well as the permanent magnet plates; the cross section of a magnetic rail chair is a ring with an opening on the upper part, a plurality of rail permanent magnet plates magnetized along the thickness direction are fixedly connected on the internal wall of the magnetic rail chair, and the permanent magnet plates enclose the coil or the combined electric conductor and the vehicle permanent magnet plates at intervals; the rail permanent magnet plates and the vehicle permanent plates are opposite in parallel with like polarity, and the coil is connected with a direct current power supply. The vehicle is levitated and guided due to the magnetic repulsion force, and the electric vehicle is propelled forward by means of the electromagnetic action generated between the electrified coil or the electrified combined electric conductor and the rail. The maglev electric vehicle has the advantages of simple structure, less magnetic leakage, higher utilization rate of the magnets, no iron loss, no pollution due to the changeable electromagnetic field, low manufacturing costs, and easy popularization.

Description

technical field [0001] The invention relates to a magnetic levitation vehicle, in particular to a magnetic levitation electric propulsion vehicle. Background technique [0002] Magnetic levitation vehicles have excellent performances such as non-contact, low vibration, low noise, safety, speed, low energy consumption, 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...
