Patent 7137675 was granted and assigned to Gs Engineering on November, 2006 by the United States Patent and Trademark Office.
A hollow-shell road wheel for tracked vehicles includes a generally triangular, outer circumferential cavity formed by an outer rim and two wall members that extend radially inward at angles to a generally planar flange at approximately the mid-radius point of the hollow-shell road wheel. A series of hollow-shell road wheels assembled in a back-to-back configuration support the tracked-vehicle and act as guides for the track of the tracked-vehicle.
