L'invention a trait au domaine des véhicules automobiles. Plus particulièrement, l'invention a trait à l'alimentation en air d'un radiateur dans le compartiment moteur à l'avant du véhicule, plus particulièrement encore à un dispositif de fermeture d'un passage d'air d'alimentation du radiateur. The invention relates to the field of motor vehicles. More particularly, the invention relates to the air supply of a radiator in the engine compartment at the front of the vehicle, more particularly to a device for closing a supply air passage of the radiator.
Un véhicule automobile comprend généralement un compartiment moteur à l'avant avec un radiateur alimenté en air. L'air alimentant le radiateur circule dans un passage d'air qui comprend une entrée située généralement au niveau de la face avant du véhicule. L'alimentation en air du radiateur n'est pas nécessaire de manière continu, elle dépend en particulier de nombreux paramètres, parmi lesquels le flux d'air dans le passage d'air généré par l'avancement du véhicule. Cependant en l'absence de demande en air du radiateur, l'air entrant dans le passage d'air dégrade le coefficient de pénétration dans l'air du véhicule et augmente la consommation du véhicule. A motor vehicle generally includes a motor compartment at the front with a radiator supplied with air. The air supplying the radiator circulates in an air passage which comprises an inlet situated generally at the level of the front face of the vehicle. The air supply of the radiator is not necessary continuously, it depends in particular on many parameters, among which the air flow in the air passage generated by the advance of the vehicle. However, in the absence of air demand from the radiator, the air entering the air passage degrades the coefficient of penetration into the air of the vehicle and increases the consumption of the vehicle.
Le document de brevet FR 2 989 938 A1 divulgue un dispositif de fermeture d'un passage d'air pour l'alimentation en air d'un radiateur qui est situé dans le compartiment moteur à l'avant du véhicule. Le dispositif de fermeture comprend un panneau mobile pour obturer le passage d'air, une grille mobile positionnée dans le passage et un système de guidage pour contrôler de manière concomitante les déplacements du panneau et de la grille. En cas de demande en air du radiateur, le système de guidage peut déplacer le panneau mobile pour libérer le passage d'air en vue d'alimenter le radiateur. Le système de guidage est apte dans le même temps à positionner la grille en travers du passage de sorte à bloquer la pénétration d'objets pouvant endommager le radiateur. L'enseignement de l'invention est intéressant en ce que le dispositif de fermeture du passage d'air est apte à obturer l'entrée d'air dans le passage d'air en l'absence de demande d'air du radiateur ce qui améliore le coefficient de pénétration dans l'air du véhicule. Cependant le système de guidage à biellettes est complexe.
