ABSTRACT:
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.
