  • Patent number: 11577614
    Abstract: A suspension frame assembly of a magnetic levitation vehicle, includes multiple suspension frames which are sequentially connected; and each suspension frame includes two longitudinal beam bodies arranged in parallel. A supporting wheel and a holding arm are fixedly provided on both ends of each longitudinal beam body; and two anti-rolling devices mounted between mounting frames of two of the supporting wheels at a same end of the two longitudinal beam bodies; and the two longitudinal beam bodies of one of the suspension frames are respectively hingedly connected to the two longitudinal beam bodies of an adjacent suspension frame; an air-spring arm beam is provided at a hinged part of the two suspension frames, and is mounted on the holding arm of one of the two longitudinal beam bodies which are hingedly connected.

  • Publication number: 20220340178
    Abstract: A linear motor comprises a primary part and a secondary part opposite to each other. An air gap is reserved between the primary and secondary parts. The air gap has first spacing in non-operating state and second spacing in operating state. The side surface of the primary part facing the secondary part is provided with a magnetically conductive film that has elasticity in the thickness direction and a thickness greater than the first spacing and less than the second spacing. The magnetically conductive film comprises magnetically conductive base bodies and non-magnetically conductive base bodies alternately distributed along the surface of the magnetically conductive film, and the magnetically conductive base bodies are filled with magnetically conductive materials. The magnetically conductive base bodies cover magnetic poles on the side surface of the primary part facing the secondary part, and the non-magnetically conductive base bodies shield gaps between the adjacent magnetic poles.
