Abstract
A bi-mobile mechanically trackable road vehicle which includes a steerable axle having steerable wheels and at least one additional unsteerable axle having unsteerable wheels. Tracking transverse guide rollers are provided in an area of the vehicle axles. The non-steerable axle is mounted in the manner of a turntable so as to be freely pivotable about a vertical axis with an arrangement being provided for automatically selectively rocking the at least one non-steerable axle in an exact transverse position when the vehicle leaves a guide track and for automatically unlocking the non-steerable axle upon an entry of a vehicle onto the guide track. At least one of the transverse guide rollers is mounted so as to be freely transversely displaceable within mechanical preset limits. A coupling arrangement is provided for coupling the automatic locking and unlocking arrangement with the at least one transverse guide roller so that the non-steerable axle is unlocked when the transverse guide roller is in an operating position and locked when the transverse guide roller is in an inoperative position.
