Description

High-speed magnetic levitation train with a narrow body and suspension frame for the same This application claims priority to the following Chinese patent applications, all of which are incorporated herein by reference in their entirety: 1) Chinese patent application No. CN202310215056.8 filed with the Chinese Intellectual Property Office on March 7, 2023 (Title: "NARROW VEHICLE BODY HIGH-SPEED MAGLEV TRAIN AND SUSPENSION FRAME THEREFOR"); 2) Chinese patent application No. CN202310666407.7 filed with the Chinese Intellectual Property Office on June 6, 2023 (Title: "MAGLEV TRAIN AND SUSPENSION FRAME THEREFOR"). This application relates to the technical field of magnetic levitation trains, in particular to high-speed magnetic levitation trains with narrow bodies and their suspension frames. With the rapid development of railway transportation, high-speed trains, conventional trains, and intercity trains have been established on a significant scale. Currently, railway transportation galleries have become a scarce resource, and space on the surface for developing high-speed magnetic levitation trains is limited, while land costs have risen significantly. Accordingly, the future direction of high-speed magnetic levitation train development is to maximize the advantage of reduced travel time by constructing underground passages (tunnels) that pass through sparsely populated mountainous areas for all or part of the high-speed magnetic levitation train route, and then entering urban centers or transportation hubs through these underground tunnels. In other words, the industry is focusing on the research and development of high-speed magnetic levitation trains with narrow chassis. The suspension frame of a conventional magnetic levitation train generally comprises two cross-beams, a longitudinal beam, support arms, and suspension electromagnets. The two cross-beams are symmetrically positioned at each of the two ends of the longitudinal beam, and support arms are provided at each of the two ends of each cross-beam. The two ends of each suspension electromagnet are connected to the inner sides of the two adjacent support arms, respectively, and only guide force is transmitted to realize suspension and directional control of the passenger car. The longitudinal beam is substantially located in the center of the suspension frame and is primarily used to transmit force in the longitudinal direction. However, the longitudinal beam occupies space for the vehicle undercarriage, thereby increasing the difficulty of installing the vehicle undercarriage. The present application discloses a high-speed magnetic levitation train with a narrow body and its suspension frame, and by optimizing the structure, pre-assembly of the suspension frame can be realized, thereby effectively simplifying the entire assembly process and reducing process costs. A suspension frame according to the present application comprises a cross beam frame assembly including two cross beam frames arranged transversely for lateral support, a two-stage suspension device, and an electromagnet module, wherein a guide electromagnet box body arranged on two sides of the electromagnet module is positioned at each of the two ends of the two cross beam frames, and each of the guide electromagnet box bodies is fixed to the two cross beam frames on the corresponding sides for longitudinal support, and the two-stage suspension device is installed on the two cross beam frames to be connected to a vehicle body. Additionally, the two-stage suspension device includes an air spring and an auxiliary air chamber positioned at the upper end of each cross beam frame; the auxiliary air chamber is provided between the lower end of a corresponding air spring and the upper end of the cross beam frame to supply a gas medium to the air spring. In addition, the main body of the cross beam frame is provided with an air spring mounting bracket, and the air spring and the auxiliary air chamber are sequentially fixed to the corresponding air spring mounting bracket. Additionally, one of the two cross beam frames has two transverse auxiliary springs in its body, and the other cross beam frame has two transverse blocking members in its body; each extended end of the two transverse auxiliary springs is positioned opposite to the corresponding auxiliary air chamber and elastically contacts the corresponding auxiliary air chamber, and each extended end of the two transverse blocking members is positioned opposite to the corresponding auxiliary air chamber and is spaced apart from the corresponding auxiliary air chamber by a first predetermined gap. Additionally, one of the two cross beam frames has two transverse auxiliary spring brackets on its main body, and the other cross beam frame has two transverse blocking brackets on its main body; each of the two transverse auxiliary springs is fixedly installed on one side of the corresponding transverse auxiliary spring bracket, and each of the two
