Guided vehicle with steered axles

Abstract From the Canadian patent

The guided vehicle has steerable axles each, of which is steered by a coupling bar connected to the axle mount at a contact point and pivoted on the body of the vehicle at a pivot point. The axle mount is mounted on the body for rotation about an axis of rotation. The distances between the pivot point the axis of rota-, tion and the contact point and the length of the coupling, bar d are chosen to position the axle radially of a curve. The pivot point of the coupling bar on the body is arranged to be substantially on the roll axis of the vehicle. The invention is especially applicable to railway vehicles for use on tracks with small radius curves such as urban railways.
