Classification: 180/266

With driven axle, mounting two or more wheels, swingable about axis of pivot, and swingable also about a horizontal axis:

(under subclass 252) Vehicle provided with at least one axle, which axle (a) is driven for a vehicle propelling purpose, (b) carries a plurality of wheels, and (c) is movable about the axis of pivot for enabling its wheels to perform a steering function, and wherein the axle is so attached to the vehicle (e.g., as by a universal joint) that it may pivot about an axis which is horizontal and is perpendicular to the axle.
