Element pour la reduction des efforts aerodynamiques d'un vehicule automobile

Abstract

L'invention concerne un élément de réduction des efforts aérodynamiques et plus particulièrement de la traînée et de la portance aérodynamique d'un véhicule automobile, caractérisé en ce qu'il comprend un aileron (10) s'étendant transversalement à l'axe longitudinal du véhicule et disposé au-dessous du soubassement (3) de ce véhicule en aval de l'essieu arrière (6).L'invention concerne aussi un véhicule automobile équipé d'un tel élément aérodynamique.
The unit has an aileron (10) extending itself transversal to a longitudinal axis of a vehicle and arranged below a base (3) of the vehicle. The aileron presents a transversal section in the form of a wing of an aircraft. The distance between the base and the aileron and/or the distance between a rear wheel shaft (6) and the aileron are controlled by a control unit according to the speed of the vehicle. An independent claim is also included for a motor vehicle.
