Description

Technical Field

[0001] The present invention relates to a "magnetic levitation roller wheel" of a "magnetic levitation train", which is a "magnetic levitation roller wheel" using "high-temperature superconducting material". Background Art

[0002] The study found that the published "a kind of maglev train" (application number: 202410536085.9) uses a "magnetic levitation roller wheel" as a suspension bearing component, and the "magnetic levitation roller wheel" has the characteristics of "outer ring" rotating while "axis" does not rotate; therefore, it is believed that this characteristic can be fully utilized to suspend and install a "liquid nitrogen tank" on its axis to store "liquid nitrogen", and use "liquid nitrogen" to provide the necessary temperature guarantee for "high-temperature superconducting materials"; in addition, it is also believed that the interior of the above-mentioned "magnetic levitation roller wheel" is a relatively "closed" environment. By using this environment, using the latest developed high-performance "insulating and thermal insulation materials", and combining with corresponding technical means, it can become a good "thermal insulation environment". With this "thermal insulation environment", it can ensure that the "high-temperature superconducting materials" can continue to play a role stably. It can reduce the consumption of "liquid nitrogen" and the cost of using "high-temperature superconducting materials". Therefore, it is believed that under the support of the above conditions, it is very feasible to make full use of the suspension ability and controllability of "high-temperature superconducting materials" to develop a "high-temperature superconducting magnetic levitation roller wheel" for the "maglev train" mentioned above. When the "high-temperature superconducting magnetic levitation roller wheel" is successfully developed, it will definitely become an option for the above-mentioned "maglev train" in terms of "maglev roller wheels".

[0011] Explanation on omitted drawings and omitted annotations in the drawings: 1. Since the left half of the drum wheel is symmetrical and basically the same as the right half, the view of the left half is omitted. Due to the omission of the view of the left half, the components at the left end of the drum wheel and their connection relationship can only be described through text description; 2. In order to make the schematic diagram concise and clear, the figure only shows the lead-out method of the "air release valve connection line". The "liquid level detector", "temperature detector" and "gas detector" connections, as well as the "suspension gap detector" connection and the power line of the "high-temperature superconductor" can be passed through the "threading hole" as long as they refer to the passing-out method, so they are not shown and labeled one by one in the figure; 3. Since it is believed that it can be passed through the attached Figure 1 The shape of the 1 / 3 circle "fan-shaped liquid nitrogen tank" shown, together with the text description, can make the technicians in this field think of the shape of the 1 / 2 circle "fan-shaped liquid nitrogen tank", so the drawing of the 1 / 2 circle (i.e., semicircle) shaped "fan-shaped liquid nitrogen tank" is omitted; 4. Since the "liquid level detection hole" and the "gas detection hole" can be referred to, the "insertion hole" of the "temperature detector" and the "air release hole" under the "air release valve" are not marked; 5. Since the "liquid nitrogen" must be filled from the left end of the "tubular shaft", since its specific filling method and its pipeline connection and valve setting are not involved in this application for the time being, the corresponding drawings are omitted; this is hereby explained.
