Abstract
A method for improving the curvilinear running speed of railway vehicles and the small tilting system: when the railway vehicle is driven on a curve, the raising and falling of air springs on both sides of the railway vehicle are controlled by a control assembly to realize small tilting of the railway vehicle toward the inner side of the curve; the transverse component of gravity after the small tilting of the railway vehicle is used for balancing part of the centrifugal force and reducing the influence of the centrifugal force, thereby improving the curve driving speed of the railway vehicle; and at the same time, an adjustable torsion bar system is controlled to provide a unidirectional anti-rolling torque for preventing the railway vehicle from rolling toward the outer side of the curve without hindering the railway vehicle from tilting slightly toward the inner side of the curve.
