ABSTRACT:
The invention relates to an omnibus track guidable vehicle for special roads which vehicle can also travel with free manual steering on normal roads. To make the trailing axle roll along the special road, which defines the track, with correct tracking and without contact, the trailing vehicle axle is provided with an elastokinematic self-steering system. Articulation of the axle body of this vehicle axle in the transverse direction is in fact made so that the axle body is transversely slidable out of the central position by approximately .+-.0.8 to 1.2% of the vehicle width with increasing force, limited as a function of the transverse force. Pull rods which determine the transverse position of the trailing vehicle axle are inclined symmetrically to the longitudinal direction of the vehicle to be arranged trapezoidally in plan view so that the intersection of the center lines of the pull rods, which constitutes a virtual pivot center, is located apporoximately 50 to 75% of the vehicle width behind the vehicle axle in the direction of travel. Alternative embodiments are shown for the mounting of the trailing vehicle axle with limited transverse mobility and with integrated resilient centering.
