Embodiment Construction

[0023] Please refer to FIG. 2. Now, the present invention will be described in detail by taking as an example that each urban rail maglev vehicle has five running frames. Since one air spring 1 is provided on each of the four corners of a running frame, a city rail maglev vehicle with five running frames has a total of 20 air springs 1. According to the height control method of the present invention, the 20 air springs 1 Divide into three groups of front, rear left, and rear right to form front, rear left, and rear right air spring suspension systems I, II, and III respectively. The front air spring suspension system I includes four air springs 1 and 1 of the first running frame. The first two air springs 1 of the second running frame are 6 air springs 1, which are evenly distributed on the left and right sides of the front end of the carriage; the air spring suspension system I is also provided with a pair of parallel height adjustment mechanisms 2, each height adjustment mechani...

Abstract

A height regulating method and system for the air-spring suspension system of magnetically levitated overhead passenger train features that all the air springs for a car is divided into front, left back and right back groups, said front group is regulated by a pair of height regulating mechanisms to control the compressed air, and said left back and right back groups are respectively regulated by own height regulating mechanism, so realizing three-point regulation.

Description

Technical field: [0001] The present invention relates to a spring suspension system of a vehicle, in particular to an air spring suspension system of a medium and low speed urban rail maglev train. Background technique: [0002] Generally, the running frames at both ends of the rail car are connected by a spring system. At present, the air spring suspension system is widely used, which controls the pressure of the four air springs arranged on the left and right sides of the car according to the load situation. , The floor height of the carriage is automatically maintained at a preset height value, and each air spring is controlled by a height adjustment valve. Figure 1 shows the structural principle of the existing air spring suspension system for rail vehicles. Each air spring 1 in the system is equipped with a height adjustment valve 2, and the height adjustment valve 2 is supplied with pipeline 5 and compressed air. Sources (such as air compressors, gas storage tanks, etc.) ar...
