METHOD FOR INCREASING CURVE DRIVING SPEED OF RAIL VEHICLE, AND SLIGHT TILTING SYSTEM

WIPO Patent Application WO/2023/206468

A1

A method for increasing the curve driving speed of a rail vehicle, and a slight tilting system. When a rail vehicle drives on a curve, compressed air, which enters air springs on two sides of the rail vehicle, is controlled, and thus the air springs on the two sides create a height difference, so that the rail vehicle slightly tilts towards an inner side of the curve, thereby increasing the curve driving speed of the rail vehicle. In addition, an adjustable torsion bar system is controlled to provide a bidirectional anti-side-rolling moment or a one-way anti-side-rolling moment, thereby meeting the safe driving requirements of the rail vehicle on different rails. On the basis of the existing structure of a rail vehicle, the rail vehicle body can generate the maximum tilting angle of 3° merely by slightly modifying the rail vehicle, and the acceleration range can reach 10%-20%. Therefore, the present invention has the advantages of a simple structure and low cost, and has good economical efficiency and practicability.
