Abstract
An endless track drive system includes a track and multiple shafts bearing outer flanges integrally secured proximate first and second ends of the shaft and a middle flange integrally secured to the shaft between the first and second outer flanges. A central wheel secures to the middle flange and engages the track. The central wheel is formed of first and second semi-circular sections combinable to form a circle. Each half section includes a rim made of polyurethane, or like polymer and a hub made of an ultra-high molecular weight (UHMW) polymer. The hub bears a plurality of projections extending radially outwardly and having a proximal portion secured to the hub and a distal portion forming an outermost portion of the hub. The distal portions are substantially larger in the circumferential direction than the proximal portion. The rim is molded around the plurality of projections.
