ABSTRACT The tracks (1) of a tracked vehicle pass around a track adjusting wheel (2) and a number of road wheels (3), the track adjusting wheel (2) being mounted on a bell-crank axle (5) that supports a piston-cylinder unit (6), and the piston-cylinder unit (6) incorporating two cylinders (10, 11) that are arranged in series. In order to create the simplest and most reliable track tensioning system that is possible, which permits a temporary increase in track tension during movement, and with which mobility is maintained even if the system becomes defective, the first cylinder (10) contains an oil or grease charge that is at constant pressure, and the other cylinder (11) is acted upon by pressurized hydraulic oil, by which means the whole of the piston-cylinder unit (6) is lengthened by a specific amount of travel. Illustration: figure 1.
