Title (EN) VEHICLE AERODYNAMICS
(FR) AERODYNAMIQUE DES VEHICULES
Abstract:
(EN) A tractor/trailer vehicle combination is made aerodynamically efficient by providing a series of air guidance surfaces for the vehicle when travelling. The surfaces include guide vanes (17) located to the rear and sides of the tractor cab (10) which surfaces are convexly shaped and aligned at their rear ends with the trailer sides (30). Further convex guides surfaces (20) are located on the cab roof to guide air towards the upper surface of the body (15) and towards the body side surfaces (30). Guide surfaces (53, 56) may also be provided on the trailer (12) including side surfaces below the trailer body to each side of the rear wheels (52).
(FR) On rend un train routier aérodynamiquement efficace en disposant une série de surfaces de guidage de l'air sur le véhicule lorsqu'il se déplace. Les surfaces comportent des pales de guidage (17) situées à l'arrière et sur les côtés de la cabine (10). Ces surfaces sont convexes et alignées à l'arrière avec les côtés de la remorque (30). Des surfaces de guidage convexes supplémentaires (20) se trouvent sur le toit de la cabine et servent à guider l'air vers le dessus du corps (15) et vers les surfaces latérales (30) de celui-ci. On peut également disposer des surfaces de guidage (53, 56) sur la remorque (12), y compris sur les surfaces latérales situées sous le corps de la remorque et de chaque côté des roues arrière (52).
