That is, the frame 1 is not directly mounted to the electromagnet 3 but indirectly mounted thereto via a mounting member, the electromagnet 3 is directly connected to the mounting member, and the mounting member and the frame 1 can be relatively floated by the buffer member 4, that is, the frame 1 can be floated with respect to the electromagnet 3, so that vibration can be effectively reduced.
Because the high-temperature superconducting maglev vehicle adopts a hinged type, only one running part (two half parts are respectively arranged at two ends of the vehicle body) is used for supporting the intermediate vehicle, so that the acting force and impact acting on the running part are very large, and the complex load working condition puts a very high requirement on the performance of the high-temperature superconducting maglev vehicle. In this embodiment, after the electromagnet 3 is installed on the installation member, the installation member is connected to the frame 1 through the buffer member 4, so that the vibration can be effectively reduced, the damage caused by the direct connection between the electromagnet 3 and the frame 1 and the vibration can be avoided, and the safety of the components and the riding comfort can be improved.
