The inventive device comprises two convergent seals (18, 20), consisting of two vertical walls (22, 24) forming the convergent elements and two vertical walls forming the seal (26, 28), said walls being articulated to one another respectively along the length of two adjacent vertical edges thereof by means of free hinges (32, 30). Moreover, the walls forming the convergent elements are also articulated by means of the other vertical edge thereof to fixed axles (34, 36) which are disposed to the rear of the bumper on either side of the radiator. The walls forming the seal can be moved, while still applied to the internal face of the bumper, between a first position in which they partially seal the air inlet opening and a second retracted position in which they completely uncover the air inlet opening. In this way, the walls forming the convergent elements (22, 24) occupy a more or less inclined position each time, in which they concentrate all of the air flow moving through the air inlet opening towards the radiator (16).

Description

Dispositif de réglage de l'ouverture d'entrée d'air à travers un pare- chocs avant de véhicule.Device for adjusting the air intake opening through a vehicle front bumper.
La présente invention concerne un dispositif de réglage de l'ouverture d'entrée d'air à travers le pare-chocs avant d'un véhicule, en fonction du type particulier de motorisation du véhicule qui est en train d'être monté sur la chaîne de montage.The present invention relates to a device for adjusting the air inlet opening through the front bumper of a vehicle, according to the particular type of motorization of the vehicle which is being mounted on the chain. mounting.
On sait que le refroidissement du moteur d'un véhicule est effectué à la fois par l'air soufflé directement sur le moteur et par un circuit de refroidissement dans lequel un liquide de refroidissement absorbe la chaleur dégagée par le moteur et l'évacué dans l'air par l'intermédiaire d'un radiateur. Celui-ci est placé immédiatement en arrière d'une calandre grillagée formée dans le pare-chocs avant du ' véhicule. A l'arrière de la calandre est fixé un convergent obturateur servant à concentrer le flux d'air entrant vers le radiateur. On sait également que le refroidissement du radiateur doit être adapté au type de motorisation (Diesel ou à essence) et à la gamme du véhicule (taille, poids et puissance) .It is known that the cooling of the engine of a vehicle is carried out both by the air blown directly on the engine and by a cooling circuit in which a coolant absorbs the heat given off by the engine and discharged into it. air through a radiator. This is placed immediately behind a mesh grille formed in the front bumper of the vehicle. At the rear of the radiator grille is fixed a converging shutter used to concentrate the incoming air flow towards the radiator. We also know that the radiator cooling must be adapted to the type of engine (Diesel or petrol) and to the range of the vehicle (size, weight and power).
Toutefois, ce type de convergent obturateur présente un certain nombre d'inconvénients liés au fait qu'il a une forme immuable et qu'il est solidaire du pare-chocs. En effet, pour tenir compte des variétés existantes de véhicules, il est nécessaire de réaliser toute une gamme de pare-chocs munis de convergents obturateurs qui définissent toutes les dimensions d'ouvertures d'entrée d'air que l'on rencontre couramment dans les véhicules. De plus, il arrive souvent que, par suite d'une erreur de manipulation, l'on fixe sur le pare-chocs en cours de montage sur le véhicule un convergent obturateur qui ne correspond pas au type de motorisation du véhicule. Si l'erreur n'est décelée qu'après que le pare- chocs a été fixé sur le véhicule, il faut le démonter et le remplacer par un autre, équipé' d'un convergent obturateur approprié. Il en résultait une perte de temps considérable.However, this type of converging shutter has a certain number of drawbacks linked to the fact that it has an immutable shape and that it is integral with the bumper. Indeed, to take account of the existing varieties of vehicles, it is necessary to produce a whole range of bumpers provided with converging shutters which define all the dimensions of air intake openings which are commonly encountered in vehicles. In addition, it often happens that, as a result of a handling error, one fixes on the bumper during mounting on the vehicle a converging shutter which does not correspond to the type of motorization of the vehicle. If the error is not detected until after the bumper has been fixed to the vehicle, it must be dismantled and replaced by another, fitted with an appropriate shutter converging. This resulted in a considerable loss of time.
La présente invention vise à remédier à ces inconvénients de la technique antérieure et à cet effet, elle propose un dispositif de réglage de l'ouverture d'entrée d'air qui est formée dans le pare-chocs avant d'un véhicule, pour le refroidissement du radiateur d'un véhicule, ledit dispositif de réglage étant caractérisé en ce qu'il comprend deux convergents obturateurs constitués respectivement de deux parois verticales formant convergent et de deux parois verticales formant obturateur qui sont articulées respectivement entre elles le. long de deux de leurs bords verticaux adjacents par des charnières libres, les parois formant convergent étant également articulées par leur autre bord vertical respectif sur des axes fixes situés à l'arrière du pare-chocs et de part et d'autre du radiateur, lesdites parois formant obturateur étant susceptibles d'être déplacées, en restant appliquées contre la face intérieure du pare-chocs, entre une première position où elles obturent partiellement l'ouverture d'entrée d'air et une seconde position escamotée où elles découvrent entièrement l'ouverture d'entrée d'air, les parois formant convergent prenant à chaque fois une position plus ou moins inclinée , où elles concentrent tout le flux d'air entrant par l'ouverture d'entrée d'air vers le radiateur.The present invention aims to remedy these drawbacks of the prior art and to this end, it provides a device for adjusting the air inlet opening which is formed in the front bumper of a vehicle, for the cooling the radiator of a vehicle, said adjustment device being characterized in that it comprises two converging shutters consisting respectively of two walls vertical forming converging and two vertical walls forming a shutter which are articulated respectively between them . along two of their adjacent vertical edges by free hinges, the converging walls also being articulated by their respective other vertical edge on fixed axes located behind the bumper and on either side of the radiator, said shutter walls being capable of being displaced, while remaining applied against the interior face of the bumper, between a first position where they partially close the air inlet opening and a second retracted position where they fully reveal the air inlet opening, the converging walls each taking a more or less inclined position, where they concentrate all the air flow entering through the air inlet opening towards the radiator.
Le changement de géométrie des obturateurs convergents peut être effectué manuellement au moyen de tirettes qui sont fixées sur les parois formant obturateur et qui sortent à travers l'ouverture d'entrée d'air.The geometry of the converging shutters can be changed manually by means of pullers which are fixed to the shutter walls and which exit through the air inlet opening.
Grâce à l'invention, on peut désormais réaliser un uniq e' pare- chocs adaptable sur les véhicules de tout type de motorisation. Cela est rendu possible par le fait que les convergents obturateurs sont indépendants du pare-chocs et qu'ils peuvent être plus ou moins dépliés ou repliés pour que les parois formant obturateur découvrent une plus ou moins grande surface sur l'ouverture d'entrée d'air..Thanks to the invention, it is now possible to produce a uniq e ' bumper adaptable to vehicles of any type of engine. This is made possible by the fact that the converging shutters are independent of the bumper and that they can be more or less unfolded or folded so that the walls forming the shutter uncover a more or less large area on the inlet opening d 'air..
De plus, le risque de démontage du pare-chocs par suite d'erreur n'existe plus. Si, lors du contrôle final sur la chaîne de montage, l'opérateur constate que les convergents obturateurs ne sont pas dans la position convenable, adaptée au type de motorisation du véhicule qui est en cours de montage, il peut facilement modifier leur position en déplaçant en mouvement de translation les parois formant obturateur au moyen des tirettes jusqu'à les amener en position appropriée.In addition, the risk of dismantling the bumper following an error no longer exists. If, during the final check on the assembly line, the operator finds that the converging shutters are not in the suitable position, adapted to the type of motorization of the vehicle which is being assembled, he can easily modify their position by moving in translational movement the walls forming a shutter by means of the pulls until bringing them to the appropriate position.
Avantageusement, les tirettes sont sécables. Une fois que les convergents obturateurs ont été amenés à leur position finale, l'opérateur casse les tirettes afin que les convergents obturateurs gardent définitivement leur position. Un mode de réalisation de l'invention sera décrit à présent, à titre d'exemple non limitatif, en regard des dessins annexés dans lesquels : la figure 1 est une vue partielle en élévation d'un pare-chocs de véhicule montrant le dispositif de réglage de l'ouverture d'air dans une position d'ouverture restreinte ; la figure 2 est une vue en coupe suivant la ligne II-I1 de la figure 1 ; et la figure 3 est une vue analogue à la figure 2, mais montrant le dispositif de réglage dans une position d'ouverture totale.Advantageously, the zippers are breakable. Once the shutter convergers have been brought to their final position, the operator breaks the zippers so that the shutter convergers permanently keep their position. An embodiment of the invention will now be described, by way of nonlimiting example, with reference to the appended drawings in which: Figure 1 is a partial elevational view of a vehicle bumper showing the device for adjusting the air opening in a restricted open position; Figure 2 is a sectional view along line II-I1 of Figure 1; and Figure 3 is a view similar to Figure 2 but showing the adjustment device in a fully open position.
On se reportera tout d'abord à la figure 1 qui représente schématiquement un pare-chocs avant 10 de véhicule. Sur le pare- chocs est formée une calandre 12 de structure grillagée. La calandre présente une pluralité d'ouvertures 14 à travers lesquelles l'air extérieur pénètre pour venir refroidir le radiateur 16 du véhicule.Reference will firstly be made to FIG. 1 which schematically represents a front bumper 10 of a vehicle. On the bumper is formed a grille 12 of mesh structure. The grille has a plurality of openings 14 through which the outside air enters to cool the radiator 16 of the vehicle.
Selon l'invention, il est prévu un dispositif de réglage de la surface d'entrée à travers la calandre, de manière à permettre l'entrée d'un flux d'air adapté au type de motorisation du véhicule. Ce dispositif comprend deux convergents obturateurs articulés 18, 20 disposés à l'arrière du pare-chocs, de part et d'autre du radiateur et symétriquement par rapport à ce dernier.According to the invention, there is provided a device for adjusting the entry surface through the grille, so as to allow the entry of an air flow adapted to the type of motorization of the vehicle. This device comprises two converging articulated shutters 18, 20 arranged at the rear of the bumper, on either side of the radiator and symmetrically with respect to the latter.
Les convergents obturateurs comprennent respectivement deux parois verticales formant convergent 22, 24 et deux parois verticales formant obturateur 26, 28 qui sont respectivement articulées entre elles le long de bords verticaux adjacents, par des charnières libres 30, 32.The converging shutters respectively comprise two vertical walls forming a converging 22, 24 and two vertical walls forming a shutter 26, 28 which are respectively hinged together along adjacent vertical edges, by free hinges 30, 32.
Les parois formant convergent 22, 24 sont elles-mêmes articulées par leur autre bord vertical sur des axes verticaux fixes respectifs 34, 36 solidaires de la structure du véhicule et se trouvant au voisinage des extrémités du radiateur.The converging walls 22, 24 are themselves articulated by their other vertical edge on respective fixed vertical axes 34, 36 integral with the structure of the vehicle and located in the vicinity of the ends of the radiator.
Les convergents obturateurs sont disposés de manière que leurs parois formant obturateur 26, 28 soient pratiquement appliquées contre la face intérieure du pare-chocs. Au voisinage des charnières 30, 32 sont fixées des tirettes 38, 40 faisant saillie à l'extérieur à travers' une des ouvertures 14 de la calandre. Ces tirettes servent à faire glisser les parois formant obturateur 26, 28 le long de la face intérieure au pare-chocs.The converging shutters are arranged so that their shutter walls 26, 28 are practically applied against the inner face of the bumper. In the vicinity of the hinges 30, 32 are fixed pull tabs 38, 40 projecting outside through one of the openings 14 of the grille. These pull tabs are used to slide the shutter walls 26, 28 along the interior face of the bumper.
On comprend à présent qu'avec le dispositif selon l'invention, on peut régler l'ouverture d'entrée d'air pour que le flux d'air entrant soit adapté au type particulier de motorisation du véhicule. Pour cela, lors du contrôle final sur une chaîne de montage, l'opérateur vérifie si les deux convergents obturateurs 18, 20 sont dans la position correcte pour assurer l'entrée d'un débit d'air adapté au type de motorisation du véhicule qui est en cours de montage. Si dans le cas d'une motorisation nécessitant un débit relativement élevé (moteur Diesel), il constate que les convergents obturateurs ne sont pas dans la position en traits tiretés sur la figure 1 où les parois formant obturateurs 26, 28 découvrent au maximum l'entrée d'air, il pourra facilement les amener dans cette position ouverte en écartant les tirettes 38, 40 l'une de l'autre. Dans ce mouvement, les parois formant obturateur 26. 28 s'éloignent l'une de l'autre et découvrent la totalité de la surface d'entrée d'air, tandis que les parois formant convergent s'inclinent davantage en formant entre elles un convergent qui concentre le flux d'air sur le radiateur 16. Au bout de leur course, les tirettes 38, 40 se brisent en contact des bords 42, 44 des ouvertures de la calandre. De même, si les convergents obturateurs se trouvent en position d'ouverture maximale alors que l'ouverture doit être restreinte, l'opérateur fermera les convergents obturateurs en rapprochant les tirettes 38, 40 l'une de l'autre. Lorsque les tirettes arrivent au bout de leur course, elles se brisent contre des barreaux verticaux 46, 48 de la calandre. En brisant les tirettes, on évite que l'utilisateur du véhicule fausse le réglage des convergents obturateurs. We now understand that with the device according to the invention, the air inlet opening can be adjusted so that the incoming air flow is adapted to the particular type of motorization of the vehicle. For this, during the final check on an assembly line, the operator checks whether the two converging shutters 18, 20 are in the correct position to ensure the entry of an air flow rate adapted to the type of motorization of the vehicle which is being assembled. If in the case of a motorization requiring a relatively high flow rate (Diesel engine), it finds that the converging shutters are not in the position in dashed lines in FIG. 1 where the walls forming shutters 26, 28 reveal at most the air inlet, it can easily bring them into this open position by moving the pull tabs 38, 40 from each other. In this movement, the shutter walls 26. 28 move away from each other and uncover the entire air intake surface, while the converging walls tilt more, forming between them a converging which concentrates the air flow on the radiator 16. At the end of their travel, the pull tabs 38, 40 break in contact with the edges 42, 44 of the openings in the radiator grille. Likewise, if the shutter convergers are in the maximum open position when the opening must be restricted, the operator will close the shutter convergers by bringing the tabs 38, 40 together. When the pull tabs reach the end of their travel, they break against the vertical bars 46, 48 of the radiator grille. By breaking the pull tabs, the user of the vehicle is prevented from altering the setting of the converging shutters.
