<p>The invention relates to traction and travel means, respectively, meant in particular to be used on unarranged terrains with low carrying capacity but also in other conditions. According to the invention, the traction effect and the travel effect, respectively, are carried out by the intake of air from the outer atmosphere, in the direction of travel, by a centrifugal fan () driven by an internal combustion engine (), by means of an intake hole (), rotating by 180° in the vertical plane, and discharge thereof into the atmosphere, in a direction opposite to the direction of travel, by means of one of the two discharge holes (), selected by means of a directing valve (), where the traction/travel means rests on the terrain by means of several pairs of wide drums (), free on their axles, provided with some braking washers ().</p> |
