US Patent 7416266 Sprocket wheel for heavy high speed multi-terrain vehicles

This invention relates to a sprocket wheel used with endless tracks used to propel heavy track laying vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved polymer sprocket wheel allowing the endless track to be driven more efficiently at highway speeds.
