| Abstract: |
A vehicle toy has front wheels and larger rear wheels provided on each of the left and right sides of a two-piece, articulately coupled chassis. Caterpillars are engaged over the front and rear wheels on each side. Twin electric motors separately drive the left and right side caterpillars through separate reduction gear transmissions and the rear wheels. The twin motors are radio controlled for separate and independent operation. Two rings of teeth on each rear wheel mesh with two rows of teeth on the inner side of each caterpillar to provide a cog drive while a higher central row of teeth on the inner side of each caterpillar is received in circumferential grooves in each of the front and rear wheels. The separate reduction gear transmissions are simultaneously manually shiftable between high and low gear ratios to provide the vehicle with the ability to run at a high speed comparable to that of other radio-controlled, wheeled vehicle toys without caterpillars and at a lower speed for longer battery life with increased torque.

1. A vehicle toy comprising:
- a vehicle chassis having separate front and rear portions and having right and left sides having a longitudinal axis;
- right and left front wheels mounted on said chassis front portion;
- right and left rear wheels mounted on said chassis rear portion;
- a single right caterpillar and a single left caterpillar each engaged over said front and rear wheels respectively on said right and left sides, said chassis being supported by said right and left front and rear wheels and caterpillars;
- first and second motors driving each of said right and left caterpillars independently of one another through said wheels; and
- an articulate coupling between said front and rear chassis portions providing at least some pivotal motion of said front and rear chassis portions with respect to one another while said vehicle toy is being operated, the articulate coupling permitting partial relative pivotal movement of the front and rear portions of the chassis with respect to one another both about an axis extending orthogonally to said longitudinal axis and laterally about said longitudinal axis.
