Abstract
A method for train suspension control by means of multiple air springs includes: receiving a vehicle load pressure; and controlling height adjustment valves according to the vehicle load pressure to adjust the pressure of a first air spring set, a second air spring set and/or a third air spring set. Three height adjustment valves are provided, and the three height adjustment valves form a triangular structure. Each of the first air spring set, the second air spring set and the third air spring set comprises a plurality of individual air springs, and all the individual air springs in each of the air spring sets are correspondingly connected to the same height adjustment valve. A system for train suspension control by means of multiple air springs and a train are further provided.
