<p>The endless track vehicle comprises a support chassis on which a box shaped body is mounted. Two driving wheels are situated near the front of the vehicle which rotate the continuous chain tracks. They are driven through two shafts which rotate through flexible joints and sprocket wheels whose diameter is half that of the vehicle wheels. The two brakes act on the sprocket wheels. They comprise a friction piece mounted on the chains which moves into contact with the rotating section which is keyed onto the wheel axle. The brakes are tensioned by the adjustment of a left hand threaded spindle, spring mounted against the chassis.</p> |
