An undercarriage structure for a track-type vehicle has first and second spaced apart roller frame assemblies which are interconnected by a pivot shaft and an equalizer bar. The first and second roller frame assemblies are so arranged with respect to the pivot shaft and the equalizer bar that the roller frame assemblies are substantially non-parallel to each other. This non-parallelism produces either "toe-out" or "toe-in" of the roller frame assemblies, which results in the endless track contacting the track rollers in different areas as the vehicle travels in forward and then reverse directions. The wear life of the endless track is thereby prolonged. |
