Description

MODULE D’ENTREE D’AIR NOTAMMENT POUR VEHICULE AUTOMOBILE  AIR INTAKE MODULE, IN PARTICULAR FOR A MOTOR VEHICLE
L'invention concerne un module d’entrée d’air notamment pour véhicule automobile. The invention relates to an air intake module especially for a motor vehicle.
Les faces avant de véhicules automobiles sont peuvent être composées d’une entrée d’air principale ou de deux entrées d’air, dites voie haute et voie basse, séparées par une poutre parechoc. Derrière cette poutre parechoc sont généralement placés les échangeurs de chaleur du véhicule automobile, comme par exemple celui utilisé pour la climatisation de l’habitacle.  The front faces of motor vehicles may be composed of a main air inlet or two air inlets, called high and low track, separated by a bumper beam. Behind this bumper beam are generally placed the heat exchangers of the motor vehicle, such as that used for the air conditioning of the passenger compartment.
Un panneau de volets est également généralement monté à l’arrière des entrées d’air du véhicule.  A flap panel is also generally mounted at the rear of the vehicle air intakes.
Les volets sont formés de lamelles montées pivotantes transversalement sur le panneau. L’inclinaison des volets peut être pilotée entre une position verticale de fermeture bloquant le passage de l’air et plusieurs positions intermédiaires jusqu’à une position horizontale d’ouverture où un flux d’air maximum peut circuler.  The shutters are formed of slats pivotally mounted transversely on the panel. The inclination of the flaps can be controlled between a vertical closing position blocking the passage of air and several intermediate positions to a horizontal opening position where a maximum air flow can flow.
Lorsque le panneau de volets est fermé, le véhicule présente un meilleur coefficient de pénétration de l’air, ce qui permet de diminuer la consommation de carburant et l’émission de CO2. En outre, les volets pilotés sont agencés devant un dispositif d’échange thermique, ce qui permet en position de fermeture, d’accélérer la montée en température des échangeurs en phase de chauffage en diminuant également la consommation du véhicule et donc rémission de CO2. Lorsque les volets sont verticaux, leurs paliers sont situés en haut et en bas. En cas de neige ou pluie, ou de tout temps, de la poussière, de l'eau ou de la boue peut parvenir sur le côté inférieur et peut rester autour du palier inférieur et de l’orifice. Combinée à des températures extrêmes, l'accumulation d'eau, de neige et de boue peut bloquer le système. Le risque d'usure du palier inférieur est élevé du fait de G accumulation de boue entre le volet et l'arbre. L’invention a ainsi pour objet un module d’entrée d’air notamment pour véhicule automobile comprenant : When the shutter panel is closed, the vehicle has a better coefficient of air penetration, which reduces fuel consumption and CO2 emissions. In addition, the controlled flaps are arranged in front of a heat exchange device, which allows in the closed position, to accelerate the temperature rise of the exchangers in the heating phase, also reducing the consumption of the vehicle and thus remission of CO2. When the shutters are vertical, their bearings are located at the top and bottom. In case of snow or rain, or any time, dust, water or mud may reach the lower side and may remain around the lower bearing and orifice. Combined with extreme temperatures, the accumulation of water, snow and mud can block the system. The risk of lower bearing wear is high due to the accumulation of sludge between the flap and the shaft. The invention thus relates to an air intake module, in particular for a motor vehicle, comprising:
- un panneau de volets, notamment pour entrée d’air de véhicule automobile, comprenant une pluralité de volets montés mobiles en pivotement autour d’un axe longitudinal de pivotement respectif, les axes longitudinaux de pivotement s’étendant notamment parallèlement les uns aux autres,  a panel of flaps, in particular for motor vehicle air intake, comprising a plurality of flaps mounted pivotally movable about a respective longitudinal axis of pivoting, the longitudinal axes of pivoting extending in particular parallel to one another,
- un support comportant au moins un palier pour recevoir un pivot de chaque volet, le support étant au moins partiellement ouvert de manière à permettre à un fluide venant s’écouler sur le pivot de s’évacuer du palier.  a support comprising at least one bearing for receiving a pivot of each flap, the support being at least partially open so as to allow fluid flowing on the pivot to escape from the bearing.
Grâce à l’invention, les gouttes d'eau ou autres fluides indésirables ne s’accumulent pas au niveau du pied, ou pivot, du ou des volets. L’invention permet ainsi de préserver le panneau de volets contre une usure accélérée, notamment par contact prolongé avec des fluides indésirables tels que de la boue ou autres. Thanks to the invention, drops of water or other undesirable fluids do not accumulate at the foot, or pivot, of the shutter or flaps. The invention thus preserves the shutter panel against accelerated wear, especially by prolonged contact with unwanted fluids such as sludge or others.
