Patent ID: 8142254

Claim:
A toy vehicle comprising: a chassis having secured thereto a pair of freely rotatable front wheels and a pair of freely rotatable rear wheels; a motor assembly for driving a main gear; a collar upwardly extending from the chassis, the collar having a pair of arcuate flanges, the pair of arcuate flanges being diametrically opposed and upwardly extending from a top edge of the collar, the collar being positioned around an aperture defined in the chassis; an annular gear positioned over the aperture, the annular gear having teeth meshed with the main gear, the annular gear being movable around the collar, such that when the main gear rotates the annular gear will rotate around the collar; a centered wheel assembly secured about the aperture in the chassis, the centered wheel assembly having at least: (a) a center drive wheel housing chassis having diametrically opposed sides with openings and opposed sides defining a channel therebetween, the opposed sides further including ledges extending outwardly therefrom and being positioned on the edge of the collar between the arcuate flanges such that the center drive wheel housing is movably between the arcuate flanges; (b) an axle extending through the openings and having attached on one end thereof a center drive wheel gear meshed to the annular gear; (c) a center drive wheel having an outer edge for contacting with a surface and being secured about the axle and positioned within the channel and sized such that when the center drive wheel housing chassis spins about the annular gear the center drive wheel spins within the aperture, and wherein when the motor rotates the annular gear, the center drive wheel gear spins the center drive wheel housing chassis until the ledges come into contact with one of the flanges, whereby the annular gear continuing to rotate drives the center drive wheel gear rotating the axle and thereby rotating the center drive wheel causing the vehicle to move.
