Problems solved by technology
However, under low vacuum conditions, the car body of the maglev train will bear a huge internal and external pressure difference, which is even higher than that of an airplane. There are extremely high requirements for the rigidity and sealing of the maglev cabin. The structure of the existing high-speed maglev train body is similar to Square shape, relatively low rigidity and tightness, its suspension, guide unit and T-shaped track beam adopt "environmentally friendly" structure, and the shape-tracking mechanism is connected horizontally through the lower part of the carriage, it is difficult to design the carriage as a circle, so a suitable for A New Architecture of High-Speed Maglev Train System Based on Vacuum Tubes

Embodiment
[0023] Such as figure 1 As shown, the present invention provides a built-in high-speed maglev train framework suitable for vacuum pipelines, including a cabin 1, a suspension frame 2, a suspension electromagnet 3, a guide electromagnet 4, a skid and a current collector 5, a concave The track beam 6, the stator core and the stator coil 7, the guide plate 8, and the support and power supply rail 9 are composed. The cabin 1 adopts an approximately circular cross-section structure, and is formed by jointing the positive bow-shaped upper cabin and the inverted bow-shaped lower cabin. The upper cabin body is a passenger cabin 10 , and the lower cabin body includes an equipment cabin 11 , a pipeline cabin 12 and an installation and maintenance cabin 13 .
[0024] The cabin 1 is completely sealed from the outside world. The electrical equipment in the equipment cabin 11 is a pluggable module. The loading and unloading and maintenance of the equipment are completed in the installation ...

The invention relates to an embedded high-speed maglev train framework suitable for a vacuum pipeline. The embedded high-speed maglev train framework comprises a vehicle cabin and a suspension drivingguide assembly that is arranged at the bottom of the vehicle cabin and embedded into a concave track beam; the vehicle cabin is completely sealed with the outside, the section of the vehicle cabin isapproximately circular, and the vehicle cabin comprises an upper cabin body with a regular arch-shaped section and a lower cabin body with an inverted arch-shaped section, and the sectional area of the upper cabin body is larger than that of the lower cabin body. Compared with the prior art, the embedded high-speed maglev train framework has the advantages of approximate circular section, reasonable space utilization, adaptability to low-vacuum pipelines, good cabin sealing performance and the like.
Description
technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to an embedded high-speed maglev train framework suitable for vacuum pipelines. Background technique [0002] The maglev train is a major technological innovation in the field of transportation. It 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, which overcomes the contact between the vehicle and the track. Wear and impact noise break through the limitation of contact force transmission of traditional wheel-rail technology. Compared with other rail transit, maglev transportation has obvious advantages, such as low noise, energy saving and environmental protection, and high safety factor. It will become a complementary travel mode with high-speed rail and aviation in the future comprehensive transportation. [0003] I...
