Abstract
A bogie for high speed rail vehicles includes an automatic control device for radially adjusting the wheel sets of the bogie. The automatic control device is mounted on the bogie frame along with a damper and a rotation locking device which connects the automatic control mechanism with the body of the vehicle. The automatic control device includes a pair of levers rotatably mounted on either side of the bogie frame. The levers are interconnected in a torsion proof rigid manner, for example, by a rigid pipe.
