A track wheel consisting of a longitudinal curved track mounted in an oval geometry on two support rollers. The track wheel is in effect an oval wheel with two axles. The axles of the two support rollers are mounted either directly or indirectly to the vehicle. The rollers support and guide both ends of the track in the small curvatures and transfers vehicle load to a surface at the lower curved part of the track. Three basically different embodiments include a spring track, a pivot hinged segment track and a band hinged segment track. All three track designs have similar bending characteristics. The track will withstand a high bending load in one direction, where it engages a surface, but it will also bend easily in the other direction, as it is guided over the two support rollers. |
