ABSTRACT:
An endless track drive system for use on a track vehicle such as a bulldozer includes a plurality of polymeric endless track drive members integrally interconnected in a closed loop to form an endless track, each drive member including at least one frictional drive face, and at least one continuous reinforcement member encased within and further interconnecting the plurality of drive members. Each drive member of the endless track preferably includes at least two lateral frictional drive faces sloping inwardly with respect to a transverse direction of the endless track for engagement with a drive wheel. The endless track also preferably includes tread members which are either integrally formed with, bonded to or removably fastened to the drive members, and the tread members may be bias-ply, fiber reinforced or cable reinforced. The drive wheel preferably is provided with drive surfaces shaped to match the shape of the lateral drive faces on the drive members and/or a sprocket for engaging with additional drive faces on the drive members. The endless track drive system also preferably includes a scraper for scraping dirt and debris from the endless track and/or the drive wheel.
