METHOD FOR TRAIN SUSPENSION CONTROL BY MEANS OF MULTIPLE AIR SPRINGS, SYSTEM FOR TRAIN SUSPENSION CONTROL BY MEANS OF MULTIPLE AIR SPRINGS, AND TRAIN

Document Type and Number:

WIPO Patent Application WO/2019/200632

Kind Code:

A1

Abstract:

Provided is a method for train suspension control by means of multiple air springs, the method comprising: receiving a vehicle load pressure (S101); 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 (S102). 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. The train load pressure is distributed more rationally so as to improve the performance of a train adapting to the curve of a track.
