ABSTRACT:
This invention relates to endless tracks and systems used to propel 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 rubber track design and system allowing the endless track to be driven more efficiently at highway speeds. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tensioning wheel, the track having a first exterior ground engaging surface and a second interior drive sprocket engaging surface, the track comprising: a carcass portion in which reinforcements are embedded into the polymer; a plurality of tread lugs disposed on the first engaging surface; a plurality of drive lugs disposed on the second engaging surface and a plurality of guide horns disposed on the second engaging surface.
