Suspension frame of medium-low speed magnetic levitation vehicle

Abstract

The invention provides a suspension frame of a medium-low speed magnetic levitation vehicle, and belongs to the technical field of manufacturing of medium-low speed magnetic levitation vehicles. The suspension frame of the medium-low speed magnetic levitation vehicle comprises longitudinal beams and anti-rolling beam assemblies, wherein the longitudinal beams are arranged on the left side and the right side correspondingly, a set of anti-rolling beam mounting seats are arranged on the two sides of the vertical center line of the inner side of each longitudinal beam correspondingly, and the anti-rolling beam assemblies are connected with the longitudinal beams through the mounting seats so as to form the suspension frame; and linear motors are located below the longitudinal beams. Boss structures serving as tenons are arranged in the positions, corresponding to the mounting seats, of the outer side faces of the longitudinal beams correspondingly, tenon holes matched with the boss structures on the outer side faces of the longitudinal beams are formed in the horizontal ends of supporting arms, the four surfaces of the supporting arms are each evenly provided with two rows of through holes, and the supporting arms are matched with the boss structures in a joggled mode and fixed through bolts. Vertical sliding sleds are arranged in the positions, close to the ends, of the inner side faces of the longitudinal beams correspondingly. The suspension frame is mainly used for manufacturing of the medium-low speed magnetic levitation vehicle.

Description

technical field [0001] The invention relates to the technical field of medium and low-speed maglev vehicles, in particular to the technical field of suspension frame design and manufacture. Background technique [0002] Compared with wheel-rail trains and high-speed maglev trains, medium and low-speed maglev trains have remarkable features such as safety, economy, quietness, and greenness. Its cost per kilometer and operation and maintenance costs are lower than those of subways and light rails. At present, a medium-low-speed maglev train has been put into commercial operation in Changsha, Hunan, my country, and there are also medium-low-speed maglev trains under construction or planning in Chengdu, Sichuan and other places. [0003] In the existing suspension frame design scheme for medium and low-speed maglev vehicles, the support arms and vertical skids are usually arranged at both ends of the longitudinal beam. The suspension frame design scheme of medium and low-speed ...
