ABSTRACT:
Apparatus for tensioning a track chain of a tracklaying vehicle, such as a bulldozer, crawler loader or excavator, including a hydraulic cylinder for biasing a reversing chain sprocket which is rotatably mounted in a bearing that is displaceable in the vertical center plane of the track chain. The hydraulic cylinder communicates with a cylinder chamber that contains a floating piston provided with a check valve for connecting the two parts of the chamber which are disposed on opposite sides of the piston, and for preventing backflow from the hydraulic cylinder. The piston is displaceable in the cylinder chamber between forward and rear stops to an extent which corresponds to that volume of hydraulic liquid which is to be displaced in order to relax the previously tensioned chain to an optimum chain tension. The cylinder chamber is connected adjacent to the rear stop to a supply line and adjacent to the front stop to a return line for returning fluid under a pressure corresponding to the pressure applied to tension the track chain. The supply line is connected to the reservoir when the piston has been moved into engagement with the forward stop.
