ABSTRACT:
A steering roller arrangement for a trackless floor vehicle in the form of a so-called three-wheeled vehicle is described. With this vehicle, in addition to two running wheels, a steering roller is provided which can be swiveled about a vertical axis by means of a ring mount for traveling in a curved line and to achieve a trailing effect. Relative to the rotatable part of the ring mount, the steering roller is movable between two opposite trailing positions such that, with a reversal of the direction of travel, the required alteration of the steering roller trailing effect is brought about by a corresponding adjustment of the steering roller. In this way uncontrolled veering of the vehicle is avoided which occur with conventional three-wheeled vehicles on account of the rotation of the steering roller by 180.degree. caused by the trailing effect of the steering roller. The steering roller is expediently displaceable in a straight line by a linear guide between the two trailing positions. The linear guide can serve at the same time as a self-aligning bearing, by mans of which the steering roller can be tilted about a horizontal axis to adapt to unevenness in the floor.
