The invention relates to a force transmission structure of a superconducting electric suspension magnet. Two superconducting magnets with built-in superconducting coils are arranged in a low-temperature container through two bearing structures which are symmetrical left and right. According to the left force bearing structure, an I-type ejector rod is arranged in the center of a superconducting magnet and abuts against the position between a bottom plate and a top plate of a low-temperature container, a plurality of I-type composite supporting rods are arranged away from the area of the symmetry plane of the two superconducting magnets, and a plurality of II-type composite supporting rods are arranged close to the area of the symmetry plane of the two superconducting magnets. The first section and the second section of the I-type composite supporting rod are connected through a screw, the upper portion of the first section is connected with the superconducting magnet through a screw, the lower end of the second section penetrates through an opening of a bottom plate of the low-temperature container and a hole of a side plate of the bogie and then is connected with a nut, and the corrugated pipe is installed between the opening of the low-temperature container and a shoulder of the second section. The first section of the II-type composite supporting rod is fixed between the superconducting magnet and the low-temperature container bottom plate, and the second section of the second-class composite supporting rod is fixed between the low-temperature container bottom plate and the bogie side plate. The structure has the characteristics that the superconducting magnet is convenient to disassemble and assemble, electromagnetic force is directly transmitted to the bogie side plate, and the design requirement for the strength of the low-temperature container is low.
