ABSTRACT:
A track adjusting flow controlling mechanism sets the optimum tension or "controlled sag" in the endless track of a track type vehicle. A piston and associated valve assembly control flow of pressurized fluid to a track adjusting clyinder. Movement of the piston tensions the track with substantially no sag ("S") and subsequent retraction of the piston provides correct track tension with an optimum track sag ("S"). Supply of pressurized fluid to the piston and valve assembly is controlled by the vehicle operator from the operator's station. Conventional track adjusting operations require considerable time and effort and are often an undesirable task. In view of this, the adjusting task is often neglected with the resulting rapid wear of the track and related components. The subject track adjusting mechanism provides a quick and simple operation to provide proper track adjustment.
