Description

PROCEDE DE PRODUCTION DE STRUCTURES AVANT D’ECHANGES THERMIQUES POUR UNE FAMILLE DE  METHOD FOR PRODUCING STRUCTURES BEFORE THERMAL EXCHANGES FOR A FAMILY OF
VEHICULES AUTOMOBILES  MOTOR VEHICLES
La présente invention concerne un procédé de production de structures avant de véhicule assurant des échanges thermiques, destinées à une famille de véhicules automobiles, ainsi qu’une structure avant de véhicule mise en oeuvre par un tel procédé de production. The present invention relates to a method for producing heat-exchanging vehicle front structures intended for a family of motor vehicles, as well as a vehicle front structure implemented by such a production method.
Les véhicules automobiles à moteur thermique, hybrides ou électriques comportent généralement à l’avant des échangeurs thermiques recevant l’air frais ambiant, permettant de dissiper des calories générées par le moteur thermique ou par les batteries d’une machine électrique de traction, ou des calories dégagées par un évaporateur d’une climatisation comprenant un cycle thermodynamique.  Hybrid or electric motor vehicles with heat engines generally comprise, at the front, heat exchangers receiving fresh ambient air, making it possible to dissipate the heat generated by the heat engine or the batteries of an electric traction machine, or calories released by an evaporator of an air conditioning including a thermodynamic cycle.
Un type de système d’échange thermique connu, présenté notamment par le document FR-A1 -2950574, comporte à l’avant du véhicule une ouverture réalisée dans la calandre recevant l’air frais lors du roulage, débouchant sur un passage avant entouré par des guides latéraux formant un conduit qui délivre l’air frais à un échangeur thermique équipé sur sa face avant de volets mobiles pilotés, et sur sa face arrière d’un ventilateur.  A known type of heat exchange system, presented in particular by the document FR-A1-2950574, comprises at the front of the vehicle an opening made in the shell receiving fresh air during taxiing, leading to a front passage surrounded by lateral guides forming a duct that delivers fresh air to a heat exchanger equipped on its front face with movable flaps controlled, and on its rear face of a fan.
Les volets mobiles pilotés permettent de fermer entièrement la face avant de l’échangeur thermique afin d’améliorer l’aérodynamisme du véhicule quand un refroidissement du moteur thermique n’est pas nécessaire. Les guides latéraux entourant le passage avant favorisent le guidage de l’air frais vers l’échangeur thermique en évitant un passage d’air sur ses côtés, et empêchent une recirculation d’air chaud venant de la sortie de l’échangeur, qui repasserait dedans à cause de turbulences.  The controlled movable flaps allow to completely close the front face of the heat exchanger to improve the aerodynamics of the vehicle when a cooling of the engine is not necessary. The lateral guides surrounding the front passage guide the fresh air towards the heat exchanger by avoiding an air passage on its sides, and prevent recirculation of hot air from the outlet of the exchanger, which would iron in because of turbulence.
D’une manière générale, le système d’échange thermique est fixé sur une façade formant une traverse supportant différents équipements disposés à l’avant du véhicule. Dans le cas d’une famille de véhicules comprenant différentes variantes de systèmes d’échanges thermiques, par exemple un véhicule équipé de volets mobiles pilotés devant l’échangeur thermique améliorant l’aérodynamisme dans les pays tempérés, et un véhicule sans volet mobile présentant devant l’échangeur thermique un passage d’air frais le plus ouvert possible pour favoriser son refroidissement dans les pays chauds, il est connu de concevoir pour chacune de ces applications un cadre spécifique équipé des guides d’air latéraux entourant le passage avant, et de fixations particulières venant se fixer sur la façade avant du véhicule. In general, the heat exchange system is fixed on a facade forming a cross support different equipment arranged at the front of the vehicle. In the case of a family of vehicles comprising different variants of heat exchange systems, for example a vehicle equipped with movable flaps piloted in front of the heat exchanger improving aerodynamics in temperate countries, and a vehicle without moving flap presenting in front of the heat exchanger a fresh air passage as open as possible to promote its cooling in hot countries, it is known to design for each of these applications a specific frame equipped with side air guides surrounding the front passage, and special fasteners that attach to the front of the vehicle.
De plus les guides d’airs latéraux doivent s’adapter à la silhouette avant du véhicule formée par la calandre et le bouclier, afin de s’ajuster au mieux sur ces éléments pour réaliser un passage avant d’air frais présentant un minimum de déperdition de débit sur les côtés.  In addition, the side air guides must adapt to the front silhouette of the vehicle formed by the grille and the shield, to adjust the best on these elements to achieve a passage before fresh air with a minimum of loss flow on the sides.
Les cadres équipés de leurs guides latéraux sont généralement réalisés par un moulage de matière plastique.  The frames equipped with their lateral guides are generally made by a plastic molding.
On doit alors concevoir une variété de cadres spécifiques comprenant ses guides latéraux pour s’adapter aux différentes demandes, ce qui entraîne des coûts de conception, des coûts de réalisation de différents outillages pour chaque variante, notamment les moules de moulage de matières plastiques, et des coûts de gestion de ces variétés. Il faut de plus prévoir des espaces suffisamment importants au bord des lignes de montage assemblant les différentes structures avant, pour stocker ces variantes.  We must then design a variety of specific frames including its lateral guides to adapt to different demands, resulting in design costs, costs of producing different tools for each variant, including molds for molding plastics, and management costs for these varieties. It is also necessary to provide sufficiently large spaces at the edge of the assembly lines assembling the different structures before, to store these variants.
La présente invention a notamment pour but d’éviter ces problèmes de l’art antérieur.  The present invention is intended in particular to avoid these problems of the prior art.
Elle propose à cet effet un procédé de production de structures avant assurant des échanges thermiques pour une famille de véhicules automobiles, chaque structure avant comportant une façade comportant une traverse inférieure et une traverse supérieure, un échangeur thermique, et un cadre disposé en amont de l’échangeur thermique, fixé à la façade, supportant des guides latéraux formant un passage d'air frais, l’échangeur thermique pouvant recevoir suivant le véhicule des volets mobiles pilotés de fermeture de sa face avant, ce procédé étant remarquable en ce qu'il comporte une étape de réalisation de façades et de guides latéraux standards, et de plusieurs types de cadres comprenant au moins un cadre avec volets mobiles et un autre cadre sans volet mobile, ces différents cadres disposant de fixations identiques pour se fixer sur les traverses et sur les guides latéraux, puis lors du montage de chaque structure avant une étape de sélection du cadre adapté parmi ces types de cadres. It proposes for this purpose a process for producing structures before ensuring heat exchange for a family of motor vehicles, each front structure comprising a facade comprising a bottom rail and a top rail, a heat exchanger, and a frame disposed upstream of the vehicle. heat exchanger, attached to the front, supporting lateral guides forming a fresh air passage, the heat exchanger can receive depending on the vehicle movable shutters controlled closing its front face, this method being remarkable in that it has a step of production of standard facades and lateral guides, and of several types of frames comprising at least one frame with movable shutters and another frame without movable shutter, these different frames having identical fastenings for fixing on the crosspieces and on the lateral guides, then during the assembly of each structure before a step of selecting the appropriate frame among these types of frames.
Un avantage de ce procédé de production est qu’il permet de réaliser plusieurs types de cadres prévus pour des échanges thermiques variés, en particulier pour une famille de véhicules adaptés pour des pays présentant des climats différents, puis de monter le cadre sélectionné sur une structure en le fixant de manière simple et rapide, à la façade et aux guides latéraux qui restent standards.  An advantage of this production process is that it makes it possible to produce several types of frames intended for various heat exchanges, in particular for a family of vehicles adapted for countries with different climates, then to mount the selected frame on a structure by fixing it simply and quickly, to the front and the side guides which remain standard.
On conserve ainsi une façade et des guides latéraux communs pour l’ensemble des véhicules de la famille, ce qui réduit le nombre de pièces différentes, diminue les coûts, et limite le stockage de variantes de ces pièces en bordure des chaînes de montage.  This maintains a common front and side guides for all vehicles in the family, which reduces the number of different parts, reduces costs, and limits the storage of variants of these parts at the edge of assembly lines.
Le procédé de production selon l’invention, ainsi qu’une structure avant réalisée avec un tel procédé de production, peuvent de plus comporter une ou plusieurs des caractéristiques suivantes qui peuvent être combinées entre elles.  The production method according to the invention, as well as a front structure made with such a production method, may further comprise one or more of the following characteristics which can be combined with each other.
En particulier, l'étape de réalisation de plusieurs types de cadres peut comporter la réalisation de cadres comprenant un ventilateur disposé en amont de l'échangeur thermique.  In particular, the step of producing several types of frames may comprise the production of frames comprising a fan arranged upstream of the heat exchanger.
L’invention a aussi pour objet un cadre de structure avant de véhicule automobile, disposé en amont d'un échangeur thermique, remarquable en ce qu'il est produit avec un procédé de production comprenant l’une quelconque des caractéristiques précédentes.  The invention also relates to a front structure frame of a motor vehicle, disposed upstream of a heat exchanger, remarkable in that it is produced with a production method comprising any one of the preceding characteristics.
En particulier, le cadre peut comporter des pattes de fixation dépassant sur le dessus de ce cadre, de fixation sur la façade.  In particular, the frame may comprise fastening tabs protruding from the top of this frame, fixing on the facade.
En particulier, le cadre peut comporter des tétons verticaux dépassant en dessous de ce cadre, de fixation sur la façade. En particulier, le cadre peut comporter un ventilateur venant en amont de l’échangeur thermique. In particular, the frame may comprise vertical pins protruding below this frame, fixing on the facade. In particular, the frame may include a fan coming upstream of the heat exchanger.
