Method for train suspension control by means of multiple air springs, system for train suspension control by means of multiple air springs, and train

A system for controlling a train suspension with multiple air springs, comprising:

• a first height adjusting valve, a second height adjusting valve, a third height adjusting valve and an air channel control device;
• wherein
• the first height adjusting valve, the second height adjusting valve and the third height adjusting valve are correspondingly connected to individual air springs in a first air spring group, a second air spring group and a third air spring group respectively, and the first height adjusting valve, the second height adjusting valve and the third height adjusting valve are distributed at three vertexes of a triangle respectively;
• the air channel control device comprises a processor;
• the processor is configured with operation instructions executable by the processor to perform the following operations:
• receiving a train load pressure;
• and
• correspondingly adjusting at least one of a pressure of the first air spring group, a pressure of the second air spring group or a pressure of the third air spring group by controlling at least one of the first height adjusting valve, the second height adjusting valve or the third height adjusting valve according to the train load pressure,
• wherein a train is composed of a plurality of carriages, and all of the individual air springs in bogies of the carriages are divided into the first air spring group, the second air spring group, and the third air spring group,
• the number of individual air springs in the first air spring group is the same as the number of individual air springs in the second air spring group, and the first air spring group and the second air spring group are located on both sides of the train along a running direction of the train respectively, and
• a center of gravity of the triangle coincides with a center of gravity of a baseplate of the train.
