Abstract: A suspension frame includes a two-stage suspension device, a cross-beam frame assembly and an electromagnet module, and the cross-beam frame assembly comprises two cross-beam frames, which are transversely arranged for transverse carrying; guide electromagnet box bodes on two sides of the electromagnet module are respectively positioned at two side ends of the two cross-beam frames, and each guide electromagnet box body is fixed to two cross-beam frames on corresponding sides for longitudinal carrying; and the secondary suspension device is arranged on the two cross-beam frames, so as to be connected to a vehicle body. Further provided is a narrow vehicle body high-speed maglev train with a suspension frame. By means of optimizing the structure of the suspension frame, it is not required to arranged longitudinal beams, such that the available space of the apparatus under a vehicle is greatly increased.
