Abstract (en)

[origin: WO9965751A1] The invention relates to a method for measuring the curvature of a track for a running gear for rail vehicles and a method for aligning in a steering manner and in accordance with the curvature of the track an axle of a rail vehicle, which axle is rotationally mounted on a running gear frame. The track curvature is calculated by dividing a yaw velocity by a forward velocity and the wheels are aligned in accordance with a specified steering angle ( gamma soll) which is calculated by multiplying the track curvature (χ) by half the distance (b) between the two axles (12, 13) of the running gear (10).
