Method and device for steering bogie of railway vehicle, and bogie

摘要

In order to solve the problem of oversteer in a straight section at an exit and to improve the curve passage performance to a level higher than that of the case in which the steering angle of the front and rear axles are set at a radial steering angle, a steering method for a steering device is configured to intentionally turn two axles (11a, 11b), which are disposed at the front and rear in the movement direction of a railway vehicle, relative to the bogie frame of a bogie (12) mounted to the railway vehicle. Steering is performed so that the steering angle (α1) of the axle (11a) on the front side in the movement direction of the vehicle is greater than the steering angle (α2) of the axle (11b) on the rear side in the movement direction of the vehicle.
