Suspension and guidance system of normally-on suction-type magnetic suspension vehicle

Abstract

The invention discloses a suspension and guidance system of a normally-on suction-type magnetic suspension vehicle, comprising two suspension modules, an orbit beam located below the suspension module, a suspension orbit, a power supply orbit, a current receptor and an electric magnet. The two suspension modules are fixedly provided with a line motor and connected with a vehicle body through an air spring; the orbit beam comprises a cement box-type beam and a cement orbit support located at two outer sides of the cement box-type beam; the suspension orbit is an L-shaped orbit; the two suspension modules are axially connected through a rotating shaft; an electric magnet bracket for fixing the electric magnet is fixed below the suspension module; a current receptor bracket for fixing the current receptor is arranged below the electric magnet bracket; the current receptor and the power supply orbit are connected in sequence between the current receptor and a lug boss; and the electric magnet comprises a suspension electric magnet and a guidance electric magnet with an E-shaped section. The invention has the advantages of simple orbit rolling technique, high labour productivity and high safety.

Description

technical field [0001] The invention relates to the field of maglev vehicles, in particular to a suspension and guidance system of a constant suction type maglev vehicle. technical background [0002] see figure 1 , the figure shows the structure of the suspension and guidance system of the medium and low-speed maglev vehicles that have been successfully developed and are currently being developed in modern times. The suspension system mainly adopts self-stabilizing guidance, and the electromagnet chooses U-shaped iron core 1′ and F-shaped track 2'. [0003] However, the rail rolling of this system is difficult, and the processing of curved rails is even more difficult. If welding and molding is used to process it with a machine tool, it will be time-consuming and laborious, and the labor productivity is very low. Part of the coil of the electromagnet is outside the iron core, which causes a large flux leakage, which can reach 20% at most, and the utilization rate of the ...
