Suspension type air spring middle-placed middle-low-speed magnetic suspension train running module

Abstract

The invention discloses a middle and low speed maglev train walking module with an air spring arranged in the middle. The invention includes a suspension frame (1), and two traction rods (2) and an air spring (3) which are arranged on the suspension frame (1), wherein, the central position of the suspension frame (1) is transversely provided with a bolster (4); both ends of the bolster (4) are supported on the suspension frame (1) by the air spring (3) below; the external sides at both ends of the bolster (2) are suspended with a hoist rod (9); the other end of the hoist rod (9) is articulated with the vehicle body. The walking mechanism has the advantages of simple structure, low production cost, easy installation and manufacture, large beeline motor power, high efficiency and fast operation speed of the maglev train.

Description

technical field [0001] The invention relates to components of a magnetic levitation train, in particular to components of a running mechanism of a medium-low speed magnetic levitation train. Background technique [0002] The running mechanism of each car of the existing domestic and foreign medium and low-speed maglev trains is composed of multiple running modules. The air springs of each running module are arranged on the four ends of the suspension frame, and the sliding table is fixed on the two air springs of the adjacent running modules. The upper part of the spring connects the adjacent traveling modules and supports the car body. The traction force generated by the linear motor stator on the suspension frame and the rotor on the track is transmitted to the sliding table through the traction rod, and then transmitted to the car body by the sliding table. There are two types of sliding tables: fixed sliding table and mobile sliding table. The running mechanism of each ...

AI Technical Summary

Problems solved by technology

[0003] 1. There are two transverse linear bearings connected to the car body on a mobile slide table. The linear bearings on the mobile slide table and the car body require extremely high installation accuracy, assembly and maintenance are extremely difficult, and high-load linear bearings, Expensive, high manufacturing and maintenance costs

[0004] 2. Since the mobile sliding table is located between the two traveling modules, two air springs are arranged on its lower part, so the number of air springs used is large and the cost is high

[0005] 3. The installation position of the mobile sliding table is the end of the suspension frame. There are many parts to be installed in this place, and the space is narrow, so it is difficult to process and install.

[0006] 4. Various components such as air springs are concentrated at the end of the suspension frame, which occupies a lot of space at the entire end, so that the length of the linear motor rotor in the middle and lower part of the suspension frame is limited at the end, and the power of the linear motor is limited; The distance between the stators of the linear motor adjacent to the suspension frame increases, the end effect of the linear motor increases, the efficiency decreases, wastes energy, and also affects the running speed of the magnetic levitation vehicle
