Abstract

A cleaning vehicle including an all-wheel steering mechanism. First, second and third wheels are mounted to the vehicle for rotation about respective first, second and third rotational axes and for pivotal movement about respective first, second and third pivot axes. The first and second wheels are located transversely across from one another and are both driven by a drive mechanism. The steering mechanism includes a pivot arm pivotally attached to the vehicle. A first steering linkage operatively connects the pivot arm to the first wheel, a second steering linkage operatively connects the pivot arm to the second wheel, and a third steering linkage operatively connects the pivot arm to the third wheel. Pivotal movement of the pivot arm causes conjoint pivotal movement of the first and second wheels in a first pivotal direction and pivotal movement of the third wheel in a second opposite pivotal direction.
