Middle or low speed magnetic suspension train running mechanism with the air spring positioned in the middle

Abstract

A middle and low speed maglev train walking mechanism with an air spring arranged in the middle consists of a movable-type walking module and a fixing-point type walking module. Both the walking modules have a bolster transversely arranged in the middle position of a suspension frame; the end part of the bolster is fixedly supported on the suspension frame by the air spring. The center of the movable-type walking module bolster is pinned with a traction block by a connecting pin; the front part and the rear part of the traction block are respectively articulated with a traction arm; the other end of the traction arm is articulated with a vehicle body; both ends of the bolster are articulated with two traction rods on the suspension frame; the external sides at two ends of the bolster are suspended with a hoist rod; the other end of the hoist rod is articulated with the vehicle body. The central position of the fixing-point walking module bolster is provided with a pin hole connected with the central pin of the vehicle body; both ends of the bolster are articulated with the traction rod on the suspension frame; the traction rod is respectively arranged on the front part and the rear part of the suspension frame. 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 a running mechanism of a medium-low speed magnetic levitation train. Background technique [0002] Usually, the running mechanism of each car in the medium-low speed maglev train is the same. In order to ensure the smooth operation of the maglev vehicle and the smooth passage of the curve, the running mechanism of each car can be equipped with at most two fixed-point running modules that can rotate with the car body but cannot be displaced laterally. When there are more than two running modules, the extra running modules must be mobile running modules capable of relative lateral displacement and rotation with the vehicle body. [0003] The main components of the fixed-point walking module are: the air springs are arranged at the four ends of the suspension frame, the slide table is fixed on the upper part of the two air springs of the adjacent walking module, connected to the adjacent walking modules and supports the vehicle b...

Problems solved by technology

[0005] However, the existing running mechanism has the following deficiencies: 1. Since the sliding table is arranged on two air springs between adjacent suspension frames, usually one running module is associated with four sliding tables and eight air springs. The travel module is also associated with eight linear bearings

In this way, the precision requirements for the linear bearing itself and the installation are very high, which makes the assembly and maintenance of the running mechanism of the magnetic levitation vehicle difficult, and the installation and maintenance costs are high.

3. The slide table and the two air springs under the slide table are used as load-bearing parts, installed on the four ends of the travel module, so that there are many parts installed at the end of the travel module, and the base at the middle and lower part of the end is wide, which limits the suspension. The length of the linear motor rotor in the middle and lower part of the frame makes the power of the linear motor smaller, and increases the end clearance of the adjacent linear motor rotors, reduces the efficiency of the linear motor, and affects the running speed of the magnetic levitation vehicle
