Problems solved by technology
The existing suspension frame assembly includes a plurality of suspension frames connected in sequence; the suspension frame is fixed with support arms at both ends of the longitudinal beam body; an air spring support arm beam for installing an air spring is installed on the support arms, and The air spring installation seat is installed on the air spring support arm beam. Since the air spring is installed above the support arm, the air bag of the air spring is exposed in the air. It is necessary to install an air spring dust cover to protect the air spring, resulting in a large weight of the suspension frame. Problems with high center of gravity and need to set up air spring dust cover

Embodiment Construction
[0052] In the process of realizing the present application, the inventor found that the air spring in the existing suspension frame is installed above the support arm, and the air bag of the air spring is exposed in the air, so it is necessary to install an air spring dust cover to protect the air spring, resulting in suspension The problem of heavy frame weight, high center of gravity and the need to install an air spring dust cover.
[0053] In view of the above problems, the embodiment of the present application provides a maglev vehicle and its suspension frame assembly. The suspension frame assembly installs the air spring in the cavity on the top of the bracket arm, so as to cancel the air spring anti-slip used in the prior art. Dust cover, transverse tie rod and air spring support arm beam, therefore, the above-mentioned magnetic levitation assembly has the advantages of small weight, low center of gravity and no air spring dust cover.
[0054] In order to make the tech...

The embodiment of the invention relates to the technical field of railway vehicles, in particular to a magnetic levitation vehicle and a levitation frame assembly thereof. The levitation frame assembly comprises a plurality of levitation frames which are connected in sequence; each levitation frame comprises two motor beams, four supporting arms and four air springs; an air spring mounting seat isarranged at the top of each supporting arm, and each air spring mounting seat is a cavity with an opening; and one air spring is accommodated in each cavity. The embodiment of the invention providesa magnetic levitation vehicle and a levitation frame assembly thereof. According to the levitation frame assembly, the cavities formed in the supporting arms are used as air spring mounting seats; theair springs are arranged in the supporting arms; not only an air spring dust cover, a transverse pull rod and an air spring supporting arm beam are removed, but also the height of the top face of theair spring can be reduced, and therefore the problems that an existing levitation frame is large in weight and high in gravity center, and the air spring dust cover needs to be arranged are solved.
Description
technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a maglev vehicle and its suspension frame assembly. Background technique [0002] With the continuous rise of the subway, subway lines are being built all over the country, but the conventional wheel-rail subway has high requirements on the foundation, and the lines on the road surface have problems of high noise, and the construction of ground lines in cities is limited by buildings and terrain. , it is difficult to achieve a line with large climbing ability and small curve radius. Therefore, as a new type of rail transportation, the medium and low-speed maglev train is more and more popular in various cities. It has the advantages of low noise, strong acceleration and braking capabilities, strong climbing ability, small turning radius, small vibration, and good comfort. . [0003] As one of the important parts of the maglev vehicle, the suspension frame assemb...
