Superconducting maglev vehicle bogie

Abstract

The invention discloses a superconducting maglev vehicle bogie. The superconducting maglev vehicle bogie comprises at least one secondary cross beam and multiple suspension guide units. Each suspension guide unit comprises a connecting beam and two dewars, wherein the two dewars are connected with the lower surfaces of the two ends of the connecting beam respectively. High-temperature superconducting block materials are arranged in the dewars, the two ends of the secondary cross beam are connected with the middle portions of the connecting beams of two adjacent suspension guide units through rotary shafts respectively, and a suspension guide unit pair is formed. By means of the superconducting maglev vehicle bogie, the loading capacity of a high-temperature superconducting maglev vehicle can be greatly improved, the curve passage capacity of the high-temperature superconducting maglev vehicle is improved, and the superconducting maglev vehicle bogie is suitable for high-load high-temperature superconducting maglev vehicles.

Description

technical field [0001] The invention relates to the manufacturing technology of a high-temperature superconducting maglev vehicle, in particular to a superconducting maglev vehicle bogie. Background technique [0002] Following my country's successful development of the world's first manned high-temperature superconducting maglev vehicle in 2000, Germany, Russia, Brazil, Japan and other countries have also carried out experiments, calculations, vehicle system prototype development and even engineering research and development work on high-temperature superconducting maglev vehicles. [0003] At present, countries in the world that have manned high-temperature superconducting maglev vehicle technology mainly include China, Germany, Brazil, etc., but limited by the scale of the test line, the vehicle generally adopts the form of a four-Dewar support body that is symmetrically arranged on the front and rear and on both sides , the suspension and guidance of the vehicle are real...

AI Technical Summary

Problems solved by technology

However, due to the lack of secondary suspension, this structure has weak anti-eccentric load capacity. When the vehicle is severely eccentrically loaded, some parts on the vehicle are under severe stress, or even fail, and do not have good usability. It is not suitable for occasions with heavy loads, and cannot meet the requirements of the current railway for large loads

[0004] In addition, the existing technology does not have good maintainability, the car body and the bogie do not adopt the concept of modular design, and the whole vehicle needs to be disassembled during maintenance, which increases the difficulty of maintenance

The existing technology does not have good safety, and the current anti-eccentric load capacity and curve passing capacity of the bogie are not enough to be applied to higher speed operating conditions

[0005] In addition, limited by the performance level of current high-temperature superconducting bulk materials and permanent magnetic track magnetic materials, high-temperature superconducting self-stabilizing magnetic levitation systems are facing major challenges in engineering, such as the growing demand for large-capacity loads, etc.
