Abstract

L'addition concerne des perfectionnements au dispositif de réduction de traînée pour véhicules de transport de charges, décrit au brevet principal. Selon l'addition, le carénage 88 peut comprendre des pattes verticales 80 à angle gamma variable, qui sont articulées en 80 degrés au voisinage des bords verticaux arriere du carénage, pour former des prolongements des parois latérales du nage et réduire encore la traînée aérodynamique. L'invention s'applique aux véhicules de transport de charges, tels que les véhicules à semi-remorque.The addition relates to improvements to the drag reduction device for load transport vehicles, described in the main patent. Depending on the addition, the fairing 88 may include vertical lugs 80 with variable gamma angles, which are hinged at 80 degrees in the vicinity of the rear vertical edges of the fairing, to form extensions of the sidewalls of the stroke and further reduce aerodynamic drag. The invention applies to vehicles for transporting loads, such as semi-trailer vehicles.
