Permanent-magnet maglev train

Abstract

The invention relates to the field of maglev trains, in particular to a permanent-magnet maglev train. The permanent-magnet maglev train comprises carriages, magnet driving wheels, guide rails, buoyancy frames and a rail pit; the magnet driving wheels are horizontally arranged on the two sides of each carriage, and the guide rails are arranged on the upper side and the lower side of each magnet driving wheel; the buoyancy frames comprise the carriage buoyancy frames and the subgrade buoyancy frames; the carriage buoyancy frames are arranged at the bottom of the carriage, the subgrade buoyancy frames are arranged at the bottom of the rail pit, and the guide rails are arranged on the inner walls of the two sides of the rail pit; each carriage is of a box structure, the magnet driving wheels are in a disc shape, and bearings are arranged in the middles of the magnet driving wheels; the magnet driving wheels are connected with the carriages through rotating shafts. The novel maglev train has the advantages that by means of the adopted structure, the train speed is high, and the running cost is low; the accelerated speed and the buoyancy are high; a light train body structure is achieved, neodymium-iron-boron permanent magnets are adopted, electric power is not needed, and energy conversation and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of magnetic levitation trains, in particular to a permanent magnetic levitation train. Background technique [0002] The maglev train is a modern high-tech rail vehicle, which realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to drive the train. [0003] In 1922, German engineer Hermann Kemper proposed the principle of electromagnetic levitation, and then applied for a patent. After the 1970s, with the increasing economic strength of industrialized countries, in order to improve the transportation capacity to meet the needs of their economic development and people's livelihood, Germany, Japan, the United States and other countries have successively carried out research and development of maglev transportation systems. Among them, Germany and Japan have made remarkable achievements. [0...

Problems solved by technology

[0008] The technical problem solved by the present invention is that in the prior art, the electromagnetic levitation train needs more power to suspend the car body, which consumes a lot of power, and the structure and control of the levitation and forward drive are complicated, the failure rate is high, and the performance is unstable. , and the cost is higher
