A vehicle is disclosed having a reduced turning radius comprising a
directional wheel assembly for turning the vehicle and a drive wheel
assembly for driving the vehicle. The drive wheel assembly has a first
and a second drive wheel independently driven by a first and a second
motor through a control circuit. A counter-rotation circuit
counter-rotates the first and second drive wheels upon a major turning
position of the directional wheel assembly to enhance the turning of the
vehicle. A reducing circuit reduces the speed of the motors upon a minor
turning position of the directional wheel assembly. The vehicle may
include a slide mechanism for providing a reduced wheelbase to further
reduce the turning radius of the vehicle. One embodiment of the invention
includes an improved steering device for controlling the directional
wheel assembly.
