Abstract:
1. Treaded vehicle wheel apparatus comprising: a substantially rigid circular wheel structure rotatable about an axis extending centrally therethrough, said circular wheel structure having a periphery from which a number of circumferentially spaced sprocket structures radially outwardly project; and a series of a number of interconnected tread links exactly equal in number to the number of said sprocket structures, disposed in a circular array coaxial with said circular wheel structure and extending externally around said periphery of said wheel structure, and being conjointly rotatable with said wheel structure about said axis, wherein the number of interconnected tread links is equal to the number of circumferentially spaced sprocket structures, and the number of circumferentially spaced sprocket structures is equal to the number of interconnected tread links, each circumferentially adjacent pair of said tread links forming an area receiving one of said sprocket structures and having bounding surfaces blocking substantial relative axial and circumferential movement between said wheel structure and said tread link array.
