ABSTRACT:
A traction device for wheels focusing on irrigation system wheels and the manufacturing process for making the traction device. Multiple traction device segments are joined to encompass a tire/wheel unit of an irrigation system tire/wheel drive system generally about the circumferential perimeter. The traction device segments are engaged by the tire/wheel unit at its circumferential perimeter causing the traction device segments to rotate as the tire/wheel unit rotates. The traction device segments have a surface which is interposed between the tire/wheel unit, at its circumferential perimeter, and the muddy ground of the irrigated field increasing the surface area of contact and decreasing the likelihood of the tire/wheel unit becoming stuck or mired in mud. A square of sheet metal is sheared at the corners along one diagonal with the two shear line forming the skirt edges of skirts. A pad is intermediate the skirts which is press formed with tread forms matching tread patterns of the tire/wheel unit. Contact between the skirt and the tire/wheel unit is reduced by press forming the skirt with a skirt form protruding toward the tire/wheel unit and rolling the skirt edge with a skirt radius. Adjoining traction device segments are connected by lugs having apertures, formed in the sheet metal by press forming or separately welded to the respective traction device segments, which align and are bolted together permitting movement between the lugs.
