ABSTRACT:
A hydraulic tensioning device for tracked vehicles comprising a hydraulically chargeable piston-cylinder unit, coupled on one end with the body of the vehicle, and with the other end to a guide wheel for the track chain which is supported on a rocker arm. In order to obtain the proper track chain tension in any operating condition without providing a separate hydraulic pump, the piston unit is equipped with a tappet supported against the piston unit by means of a spring unit. The tappet closes off a secondary cylinder chamber in the piston unit which is connected with the principal cylinder chamber by two check valves which seal in opposite directions. The tappet effects a pumping action as the result of the vibration generated by the chain links running in and out the guide wheel, thereby pumping the hydraulic oil from a hydraulic oil reservoir into the secondary cylinder chamber and from there into the principal cylinder chamber.
