Abstract

A six wheeled vehicle with two front steerable wheels and four rear coaxial non-steerable left and right wheels pair driven by separate longitudinal shafts fitted with bevel gears of unequal diameter driving each wheel via an integral speed reduction/correction gearbox further driven by speed correcting hydraulic motors. The rear wheels are driven a speed which produces the same centre of curvature for the path of the vehicle as the driver-selected angles of the front wheels. A vehicle with individually driven wheels at least one of which is steerable where the speed of driven wheels and wheels angles are integrally controlled to produce a single centre of curvature for the path of the vehicle and where steerable wheels are driven by a gear train including a substantially vertical shaft allowing the wheel to be turned at least 180°. A gantry tractor consisting of plurality of four wheeled modules hitched together where the hitch angle can be controlled by a pair of actuators linking together the corners of the modules.
