ABSTRACT:
A track drive converter for two or four wheel driven vehicles is disclosed. The converter has three interworking elements: a track, a wheel disc and a roller assembly. Each set of tires on a vehicle's side is overfitted with one track. Each wheel is fitted with two discs and each tire is provided with a roller assembly. The track is composed of padded links and connectors. The links are made of three parallel rods joined at their ends by an omega-shaped bracket. Also attached to the brackets are the connectors which are a series of three end-to-end, movably connected, bars. Each bar may move independently of its mates, allowing a set of links to compress along one edge and remain apart on their opposite edges. This compression provides the curvature in the track needed for turning. The track drive is provided by teeth on the link sets meshing with indents on the wheel disc. The track is tensioned by rollers positioned at each tire. The rollers, attached to hydraulic pistons, provide constant tension to the track. Because the pistons are provided with slidable brackets which ride in channels on the vehicle's underside, the rollers (through the pistons) provide constant pressure to the track as the wheels turn. Thus, using the vehicle's own steering assembly, a vehicle fitted with track, rollers and discs is converted from a wheel drive to a track drive vehicle.
