Abstract

A self-steering running gear for rail vehicles includes at least one Bissel-type axle. Through a proper geometrical proportioning of the running gear, the Bissel-type axle is oriented in a perfectly radial condition along a constant radius curve, in a real or in a virtual mode. In both cases perfectly radial orientation along a constant radius curve of at least another steerable axle of the running gear may be operated. Expedients are further provided to reduce the effects deriving from the sum of radiality errors of the axles during the transition phases.
