A maglev train running mechanism

Abstract

The invention discloses a maglev running mechanism comprising five suspension modules sequentially arranged in the vertical direction; the suspension modules comprise left longitudinal beams and rightlongitudinal beams; the top portions of the left longitudinal beams and the right longitudinal beams are fixedly provided with traction rods; the top portions of the left longitudinal beams and the right longitudinal beams of a first suspension module, a third suspension module and a fifth suspension module are provided with moving sliding tables fixedly connected with a car body; the top portions of the left longitudinal beams and the right longitudinal beams of a second suspension module, and a fourth suspension module are provided with fixed sliding tables fixedly connected with the car body; each moving sliding table and each fixed sliding table are connected with the traction rod on each corresponding suspension module in a hinged mode; the moving sliding tables in the first suspension module, the third suspension module and the fifth suspension module are connected in series through a link gear and synchronized driving is achieved; and suspension modules are independent of eachother. The maglev running mechanism creatively adjusts in series connection positional relation between the link gear and different sliding tables, so that the effect of the lateral load on the stability of the suspension is reduced to the lowest, and the maglev running mechanism has the advantages of high torsion stiffness and good stability.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a running mechanism of a maglev train. Background technique [0002] Affected by the length of the vehicle and the power supply capacity, the running mechanism of the existing medium and low-speed maglev trains generally adopts a five-module structure, with six sets of slide structures, and a set of guide mechanisms is set between the first, third, fourth, and sixth positions. [0003] Chinese patent 200710049936.3 discloses a running mechanism for medium and low-speed maglev trains with air springs in the middle, which consists of mobile and fixed-point running modules. The part is fixed and supported on the suspension frame by air springs. The center of the bolster of the mobile walking module is connected with a traction block through a connecting pin, and the front and rear of the traction block are respectively hinged with a traction arm, and the other end of ...

AI Technical Summary

Problems solved by technology

[0005] 1. Each suspension frame unit is connected to each other, which is not convenient for production assembly and daily disassembly and maintenance

[0006] 2. Each sliding table is relatively independent, and will bear a large lateral force when running through curves and other road conditions, and the positions of the curves entered by each suspension frame unit are different, and the lateral force they bear is different, and the stability of the vehicle is poor.

[0007] 3. There is only one bolster structure connecting the left and right longitudinal beams of the suspension module, which has poor torsional rigidity, is easily deformed by torsion, and has an unstable structure

[0008] 4. Poor lateral stability in the existing running mechanism
