摘要： A vehicle running system based on rail transport, including a track, a framework, two levitation devices and a running device. The track is provided with a slot, in which the framework is provided. The levitation devices are provided between the track and the framework, and a top surface of the levitation device is fixedly connected to a bottom surface of the framework through a suspension structure. The running device includes two conductor plates and two running structures. The conductor plates are fixedly arranged on the inner wall of the slot, and are corresponding to the running structures. The reluctance force of magnetic wheels is converted into a driving force to drive maglev vehicles, and the levitation force is converted into a guiding force to realize the self-stabilization of vehicle guidance.

摘要： The present invention discloses a superconducting bulk cooling apparatus and cooling method for a high-temperature superconducting magnetic levitation vehicle. The superconducting bulk cooling apparatus for the high-temperature superconducting magnetic levitation vehicle includes a refrigerating machine, a vacuum box and a Dewar tank. A condensing tank is arranged in the vacuum box, and the condensing tank is communicated with the Dewar tank through a nitrogen siphon pipe and a liquid nitrogen return pipe; a heat exchanger connected with the refrigerating machine is arranged in the condensing tank; and a flexible isolation pipe for thermally insulating and isolating the nitrogen siphon pipe and the liquid nitrogen return pipe is connected between the vacuum box and the Dewar tank. The present invention pumps the phase-change nitrogen out of the Dewar tank through a siphoning effect, so that the immersion cooling of high-temperature superconducting bulks is separated from the re-condensation of the nitrogen.
