Description

BLOC AVANT COMPACT DE VEHICULE A MOTEUR  FRONT COMPACT BLOCK OF MOTOR VEHICLE
[0001] La présente invention revendique la priorité de la demande française 0955102 déposée le 22 juillet 2009 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of the French application 0955102 filed July 22, 2009 whose content (text, drawings and claims) is here incorporated by reference.
[0002] La présente invention concerne un bloc avant d'architecture compact pour un véhicule à moteur, en particulier pour un véhicule automobile à moteur 3 cylindres, dénommé aussi : « Bloc avant compact ». The present invention relates to a compact architecture front block for a motor vehicle, in particular for a motor vehicle with 3-cylinder engine, also called: "Compact front block".
[0003] De manière classique, dans les véhicules automobiles actuels, le résonateur d'air aspiré, implanté dans l'espace désigné « sous-capot », est disposé, selon la direction longitudinale du véhicule, entre le groupe motopropulseur et le système de refroidissement du moteur, c'est-à-dire principalement le radiateur. [0003] Conventionally, in today's motor vehicles, the suction air resonator, implanted in the space designated "under-hood", is arranged, in the longitudinal direction of the vehicle, between the powertrain and the control system. engine cooling, that is to say mainly the radiator.
[0004] On a déjà cherché à gagner de l'espace dans la partie avant des véhicules automobiles. We have already sought to gain space in the front part of motor vehicles.
[ooo5] A titre d'exemple, le document JP 81 14120 A2 décrit un cadre de ventilateur de radiateur sur lequel est fixé un résonateur. Le résonateur est intégralement formé - c'est-à-dire formé en une seule pièce - avec le corps principal du cadre du ventilateur, de façon à réduire à la fois le nombre de pièces, les opérations d'assemblage et l'espace occupé. By way of example, JP 81 14120 A2 describes a radiator fan frame to which a resonator is attached. The resonator is integrally formed - i.e. formed in one piece - with the main body of the fan frame, so as to reduce both the number of parts, the assembly operations and the occupied space .
[0006] A titre d'exemple également, le document FR 2 879 155 décrit un support de façade avant de véhicule automobile, qui comporte une cavité intégrée formée par la réunion d'une première demi-coque faisant partie du support de face avant et d'une deuxième demi-coque réalisée séparément. Les deux demi-coques présentent des zones de jonction respectives qui sont assemblées entre elles pour former conjointement une coque creuse. Cette coque peut servir de réservoir pour contenir différents types de fluides tels que, par exemple, un liquide caloporteur, un liquide de lave-glaces, un liquide de freinage, etc. [0007] Un autre exemple est aussi donné par le document US 2005/0279547 A1 , qui décrit une structure de bloc avant de véhicule, dans laquelle un réservoir de liquide ou un résonateur d'air aspiré est monté sur une façade avant. La façade est en résine et sensiblement en forme de cadre. Elle présente une ouverture dans laquelle est disposé un échangeur thermique. Elle est formée « monobloc » sur chacun de ses deux bords latéraux avec des pièces de fixation de caisse qui sont destinées à être fixées sur les longerons avant de droite et de gauche, respectivement. Les pièces de fixation sont également « monobloc » sur leur partie extérieure selon la direction transversale du véhicule avec des pièces de positionnement de carter sur lesquelles viennent se monter un carter de réservoir de liquide et un autre carter pour un résonateur d'air aspiré au voisinage des deux pièces de fixation de caisse, respectivement. By way of example also, the document FR 2 879 155 discloses a motor vehicle front support, which comprises an integrated cavity formed by the union of a first half-shell forming part of the front face support and a second half-shell made separately. The two half-shells have respective junction zones which are joined together to form a hollow shell. This shell can serve as a reservoir for holding different types of fluids such as, for example, a coolant, a washer fluid, a brake fluid, etc. Another example is also given by the document US 2005/0279547 A1, which describes a vehicle front block structure, wherein a liquid reservoir or a suction air resonator is mounted on a front panel. The facade is resin and substantially shaped frame. It has an opening in which is disposed a heat exchanger. It is formed "monobloc" on each of its two side edges with body fasteners which are intended to be fixed to the front rails of right and left, respectively. The fasteners are also "monobloc" on their outer part in the transverse direction of the vehicle with crankcase positioning parts on which are mounted a liquid tank housing and another housing for an air resonator sucked in the vicinity two body fasteners, respectively.
[oooδ] Le but de la présente invention est de fournir un bloc avant de véhicule qui, selon la direction longitudinale du véhicule, soit plus compact que les blocs avant connus de l'art antérieur, de façon à libérer un espace substantiellement important sous le capot moteur. The object of the present invention is to provide a vehicle front block which, in the longitudinal direction of the vehicle, is more compact than the known front blocks of the prior art, so as to release a substantially large space under the bonnet.
[0009] Un autre but de la présente invention est de fournir un tel bloc avant, dont l'architecture nouvelle permette une réduction sensible du porte-à-faux avant du véhicule. [ooio] Enfin, c'est également un but de la présente invention de fournir un tel bloc avant, qui soit de conception, de réalisation et de montage simple, qui apporte un gain en masse et qui soit économique. Another object of the present invention is to provide such a front block, the new architecture allows a significant reduction of the front overhang of the vehicle. [ooio] Finally, it is also an object of the present invention to provide such a front block, which is of design, construction and simple assembly, which provides a gain in mass and is economical.
[0011] Pour parvenir à ces buts, la présente invention a pour objet un bloc avant qui comprend notamment un résonateur d'air aspiré en liaison avec le filtre à air du véhicule et une façade avant technique, qui est située, selon la direction longitudinale du véhicule, entre le groupe motopropulseur et la poutre d'absorption d'énergie des chocs. Dans cette façade est intégré au moins le radiateur du système de refroidissement du moteur. Selon le principe de la présente invention, le résonateur est également intégré dans la façade avant technique et s'étend sensiblement dans le plan de cette dernière, de façon à libérer de la place sous le capot du véhicule et à réduire le porte-à-faux avant du véhicule. To achieve these goals, the present invention relates to a front block which comprises in particular an air resonator sucked in connection with the vehicle air filter and a front technical front, which is located in the longitudinal direction of the vehicle, between the powertrain and the energy absorbing beam of shocks. In this facade is integrated at least the radiator of the engine cooling system. According to the principle of the present invention, the resonator is also integrated in the front technical front and extends substantially in the plane of the latter, so as to free up space under the vehicle hood and reduce the front overhang of the vehicle.
[0012] La façade avant technique est constituée par un cadre. Selon le mode de réalisation de l'invention, le radiateur est monté sur la partie de la façade avant technique située sur le côté gauche du véhicule, tandis que le résonateur est monté sur la partie de ladite façade située sur le côté droit du véhicule. The front technical front is constituted by a frame. According to the embodiment of the invention, the radiator is mounted on the part of the front technical front located on the left side of the vehicle, while the resonator is mounted on the portion of said facade located on the right side of the vehicle.
[0013] Selon un mode préféré de réalisation de l'invention, le résonateur est monté sur la façade avant technique de façon à être entièrement situé à une distance suffisante au dessus de la poutre d'absorption d'énergie des chocs pour ne pas être impacté en cas de choc et de recul de ladite poutre. According to a preferred embodiment of the invention, the resonator is mounted on the front technical front so as to be entirely located at a sufficient distance above the energy absorption beam shocks to not be impacted in case of shock and recoil of said beam.
[0014] Cette distance suffisante peut avantageusement être de l'ordre de 5mm au moins. This sufficient distance may advantageously be of the order of 5mm at least.
[0015] Le cadre constitutif de la façade présente une forme sensiblement rectangulaire avec deux profilés sensiblement horizontaux, deux profilés latéraux sensiblement verticaux et un profilé intermédiaire sensiblement vertical partageant l'espace d'intégration du radiateur et l'espace d'intégration du résonateur. The constituent frame of the facade has a substantially rectangular shape with two substantially horizontal profiles, two substantially vertical side profiles and a substantially vertical intermediate profile sharing the integration space of the radiator and the integration space of the resonator.
[0016] De plus, le cadre présente à ses deux angles supérieurs un moyen d'appui et de fixation du cadre sur la structure droite et la structure gauche de la caisse du véhicule, respectivement. In addition, the frame has at its two upper corners a means of support and attachment of the frame on the right structure and the left structure of the vehicle body, respectively.
[0017] De préférence, les moyens de positionnement du résonateur sur le cadre de la façade avant technique sont réalisés directement et ensemble avec ladite façade, et par conséquent « monoblocs » avec cette dernière. Preferably, the resonator positioning means on the frame of the front technical front are made directly and together with said facade, and therefore "monoblocks" with the latter.
[0018] La façade avant technique peut être réalisée en matière plastique. [0019] Le volume du résonateur peut être sensiblement de l'ordre de 3 litres. [0020] L'invention a également pour objet un véhicule à moteur, en particulier un véhicule muni d'un moteur comportant 3 cylindres, qui comporte un bloc avant compact conforme à celui décrit ci-dessus dans ses grandes lignes. The front technical front can be made of plastic. The volume of the resonator may be substantially of the order of 3 liters. The invention also relates to a motor vehicle, in particular a vehicle with a motor having 3 cylinders, which comprises a compact front unit conform to that described above in outline.
[0021] D'autres buts, avantages et caractéristiques de l'invention apparaîtront dans la description qui suit d'un mode de réalisation préféré, non limitatif de l'objet et de la portée de la présente demande de brevet, accompagnée de dessins dans lesquels : Other objects, advantages and features of the invention will appear in the following description of a preferred embodiment, not limiting the object and scope of the present patent application, accompanied by drawings in which :

FIG. 5 is a front view showing the position, in the vertical direction, of the resonator with respect to the energy absorption beam in the event of an impact.
[0022] En référence au dessin des figures 1 et 2, on a représenté une architecture de bloc avant selon le principe de la présente invention. Le résonateur d'air aspiré, de référence 1 , est intégré dans la façade avant technique, de référence générale 2. A titre d'exemple, il peut s'agir d'un résonateur d'un volume sensiblement de l'ordre de 3 litres. La façade avant technique 2 est, selon la direction longitudinale du véhicule (axe XX de la figure 2), comprise entre le groupe motopropulseur 3 du véhicule et la poutre d'absorption d'énergie, appelée aussi poutre anti-choc, référencée 4. La façade intègre également le radiateur 5 du système de refroidissement du moteur. La référence 6 (figure 2) désigne le conduit du résonateur 1 qui relie, de manière connue en soi, ce dernier au filtre à air. With reference to the drawing of Figures 1 and 2, there is shown a front block architecture according to the principle of the present invention. The aspirated air resonator, reference 1, is integrated in the front technical front, general reference 2. For example, it may be a resonator with a volume substantially of the order of 3 liters. The front technical front 2 is, in the longitudinal direction of the vehicle (XX axis of Figure 2), between the powertrain 3 of the vehicle and the energy absorption beam, also called shock beam, referenced 4. The facade also incorporates the radiator 5 of the engine cooling system. The reference 6 (FIG. 2) denotes the duct of the resonator 1 which connects, in a manner known per se, the latter to the air filter.
[0023] Cette architecture nouvelle permet, contrairement aux implantations classiques du résonateur entre le groupe motopropulseur (GMP) et la façade avant technique, de réduire considérablement le porte-à-faux avant du véhicule en évitant l'empilage GMP/résonateur/radiateur selon l'axe XX du véhicule. La présente invention réduit la longueur de cet empilage en plaçant sur le même niveau longitudinal le résonateur et la fonction refroidissement. This new architecture allows, unlike conventional implementations of the resonator between the powertrain (GMP) and the front technical, significantly reduce the front overhang of the vehicle avoiding the stacking GMP / resonator / radiator according to the axis XX of the vehicle. The present invention reduces the length of this stack by placing on the same longitudinal level the resonator and the cooling function.
[0024] La façade avant technique 2 est constituée essentiellement par un cadre, sur lequel sont fixés le résonateur 1 et le radiateur 5. The front technical front 2 consists essentially of a frame, on which are fixed the resonator 1 and the radiator 5.
[0025] Ce cadre est mieux représenté sur la figure 3, le radiateur 5 étant monté sur la partie de la façade avant technique située sur le côté gauche du véhicule, tandis que le résonateur 1 est monté sur la partie de ladite façade située sur le côté droit du véhicule. [0026] Le cadre 2 est réalisé en matière plastique et présente une forme sensiblement rectangulaire avec deux profilés 2a, 2b sensiblement horizontaux, deux profilés latéraux 2c, 2d sensiblement verticaux, et un profilé intermédiaire 2i sensiblement vertical partageant l'espace d'intégration du radiateur 5 et l'espace d'intégration du résonateur 1. [0027] Le cadre présente à ses deux angles supérieurs un moyen d'appui et de fixation 2F1 , respectivement 2F2, du cadre 2 sur la structure droite 7 (longeron avant droit) et la structure gauche 8 (longeron avant gauche) de la caisse du véhicule, respectivement. This frame is best shown in Figure 3, the radiator 5 being mounted on the part of the front technical front located on the left side of the vehicle, while the resonator 1 is mounted on the part of said facade on the right side of the vehicle. The frame 2 is made of plastic and has a substantially rectangular shape with two substantially horizontal sections 2a, 2b, two lateral profiles 2c, 2d substantially vertical, and an intermediate profile substantially vertical section 2i sharing the integration space of the radiator 5 and the integration space of the resonator 1. The frame has at its two upper angles a support and fixing means 2F1, respectively 2F2, of the frame 2 on the right structure 7 (right front spar) and the left structure 8 (left front spar) of the vehicle body, respectively.
[0028] Comme illustré par le dessin de la figure 4, on notera que les moyens de positionnement et de fixation du résonateur 1 sur la façade avant technique 2 sont réalisés directement et ensemble avec la façade 2, et sont par conséquent « monoblocs » avec cette dernière. Les moyens de positionnement, en matière plastique, reçoivent le résonateur par concordance de formes, et des moyens de fixation, de type vis par exemple, viennent immobiliser le résonateur 1 sur le cadre. As illustrated by the drawing of Figure 4, it will be noted that the positioning and fixing means of the resonator 1 on the front technical front 2 are made directly and together with the front 2, and are therefore "monoblocks" with the latter. The positioning means, made of plastic, receive the resonator by matching shapes, and means of fixation, screw type for example, immobilize the resonator 1 on the frame.
[0029] Comme représenté sur le dessin de la figure 5, le résonateur 1 est monté sur la façade avant technique 2 de façon à être entièrement situé à une distance « D » suffisante au dessus de la poutre d'absorption d'énergie des chocs 4 pour ne pas être impacté en cas de choc et de recul de ladite poutre 4. As shown in the drawing of Figure 5, the resonator 1 is mounted on the front technical front 2 so as to be entirely located at a distance "D" sufficient above the energy absorption beam shocks 4 to not be impacted in the event of impact and recoil of said beam 4.
[0030] Cette distance « D » suffisante est de l'ordre de 5mm au moins. This distance "D" sufficient is of the order of 5mm at least.
[0031] La référence 10 (figures 3 et 5) désigne la serrure du capot du véhicule. The reference 10 (Figures 3 and 5) designates the lock of the hood of the vehicle.
[0032] Le bloc avant décrit ci-dessus présente de nombreux avantages, parmi lesquels les avantages suivants : The front block described above has many advantages, among which the following advantages:
• il permet de libérer de la place dans l'espace sous le capot, • it frees space in the space under the hood,
• il permet de réduire substantiellement le porte-à-faux avant du véhicule, tout en respectant les contraintes liées à la protection des piétons en cas de choc (réglementations sur les « chocs piéton »), • il permet une réduction de la masse du véhicule, notamment par le fait de rapprocher le radiateur du moteur et de supprimer tout support spécifique pour le résonateur, • it allows the front overhang of the vehicle to be substantially reduced, while respecting the constraints related to the protection of pedestrians in the event of impact ("pedestrian impact" regulations), • it allows a reduction in the mass of the vehicle; vehicle, in particular by bringing the radiator closer to the engine and removing any specific support for the resonator,
[0033] De plus, la nouvelle architecture du bloc avant n'est pas contraignante pour le style, la position d'entrée d'air du résonateur nouvellement placé étant symétrique à celle du résonateur dans l'architecture antérieure. In addition, the new architecture of the front block is not binding for the style, the air intake position of the newly placed resonator being symmetrical to that of the resonator in the prior architecture.
[0034] Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits et représentés ci-dessus à titre d'exemples ; d'autres modes de réalisation peuvent être conçus par l'homme de métier sans sortir du cadre et de la portée de la présente invention. Of course, the present invention is not limited to the embodiments described and shown above as examples; other embodiments may be devised by those skilled in the art without departing from the scope and scope of the present invention.
