<p>A chassis (16) supports a toy vehicle body (11) and a pair of front wheels (14, 15) together with a pair of rear wheels (12, 13). A dual motor differential drive mechanism provides independent differential steering and propulsion of the vehicle through remote control of the rear wheels. An integral steering caster (51) supporting both front wheels in a common caster apparatus is pivotally supported by a single forwardly positioned pivot (50) between the chassis and the caster. The pivoting action of the common caster in response to vehicle turning moves the inner one of the front wheels rearwardly while moving the outer one of the front wheels in a turn forwardly. This pivotal movement is accomplished with a simple, low cost steering caster and provides a heightened appearance and performance effect.</p> |
