Embodiment Construction

[0029] figure 1 It is a structural schematic diagram of the vacuum tube maglev train of the present invention, and the train supporting system is composed of an EMS system, an EDS system and some connecting supports.

[0030] For the EMS system, the specific structure is as follows: the electromagnet 4 is fixed on the electromagnet support platform 5 through screw connection, and is fixedly connected on the train body 6 . Directly opposite to the electromagnet 4 is the armature plate 3 . The electromagnetic attraction force is generated by the attraction force between the electromagnet 4 and the armature plate 3 . The armature plate 3 is fixed by its support plate 2 through a screw connection, and is connected with the vacuum pipeline 1 .

[0031]For the EDS system, the specific structure is as follows: the permanent magnet array is fixed in the magnet disk 11 and connected to the magnet support frame 8 through threads. The induction plate 12 (which may be an aluminum plate...

Abstract

The invention discloses a vacuum-pipe-train magnetic suspension EMS / EDS mixed supporting structure. A train with the circular cross section is arranged in a vacuum pipe with the circular cross section, and a four-point-suspension-supporting structure symmetrically arranged in the circumferential direction is adopted between the train and the pipe; the lower portion of the train adopts an EDS suspension supporting structure to bear most loads, and an EMS suspension supporting structure assists the upper portion of the train in supporting. The EMS / EDS mixed supporting structure simultaneously provides damp, and the system stability is increased. The problems that in a current magnetic-suspension-train supporting system, damp of a single EDS system is insufficient, the stability of the systemis poor, a suspension gap of a single EMS system is small, and the requirement for the control system and structure accuracy is high are solved.

Description

technical field [0001] The invention relates to a suspension system of a maglev train, in particular to a suspension system for mixing EMS and EDS of a vacuum pipeline train. Background technique [0002] The maglev train is a modern rail vehicle, which achieves non-contact suspension between the train and the track through the attraction or repulsion of magnets, thereby greatly increasing the running speed. At the same time, it has many advantages and characteristics such as energy saving and environmental protection, and has broad development prospects. The suspension frictionless design solves the friction problem between the train and the wheel rail. But do not fundamentally solve the problem of the resistance that air brings to train running. Using vacuum pipeline technology to change the operating medium of the train, the maglev train running in the pipeline can greatly reduce the frictional resistance and air of the existing ground vehicles. As a future means of tr...
