Description

AGENCEMENT POUR LE MONTAGE D'UNE FACE AVANT TECHNIQUE DE VEHICULEARRANGEMENT FOR THE MOUNTING OF A FRONT PANEL TECHNICAL VEHICLE

AUTOMOBILE L'invention concerne un agencement pour le montage d'une face avant technique de véhicule automobile, destinée à supporter des équipements du véhicule et destinée à être montée à une extrémité d'un élément de structure avant du véhicule comportant au moins une traverse supérieure ainsi que deux longerons reliés entre eux par une traverse inférieure.  The invention relates to an arrangement for mounting a technical front end of a motor vehicle, intended to support vehicle equipment and intended to be mounted at one end of a front structural member of the vehicle comprising at least one upper cross member. and two longitudinal members interconnected by a lower cross.

Dans certains véhicules automobiles, il peut arriver que le module de io refroidissement soit porté par la face avant technique au lieu d'être porté par la traverse inférieure.  In some motor vehicles, it may happen that the cooling module is carried by the technical front instead of being carried by the lower rail.

Cependant ce type de configuration ne permet pas ou bien rend difficile et inadaptée l'utilisation de moyens habituels de montage de la face avant technique, une face avant technique étant souvent 15 montée par le dessous selon une direction verticale, comme décrit dans la publication FR-A-2838094. Afin de pallier ces inconvénients, l'invention a pour objet un agencement pour le montage d'une face avant technique permettant d'utiliser l'outillage déjà prévu pour le montage de la traverse 20 inférieure. A cet effet, l'invention propose un agencement pour le montage d'une face avant technique du type cité ci-dessus, caractérisé en ce que la face avant technique est solidaire de la traverse inférieure.  However this type of configuration does not allow or makes it difficult and unsuitable the use of usual means of mounting the front panel technique, a technical front face is often mounted from below in a vertical direction, as described in the publication FR -A-2838094. In order to overcome these drawbacks, the object of the invention is an arrangement for mounting a technical front panel enabling the tooling already provided for mounting the lower rail 20 to be used. For this purpose, the invention proposes an arrangement for mounting a technical front face of the type mentioned above, characterized in that the technical front face is secured to the lower cross member.

Selon d'autres caractéristiques de l'invention: 25 - Un bord inférieur de la face avant technique est monté à pivotement sur la traverse inférieure autour d'un axe transversal, la face avant technique présentant en outre un bord supérieur comportant au moins une partie saillant vers l'arrière et/ou latéralement, de manière que la face avant technique passe : - 2 -d'une première position dite non montée dans laquelle elle est basculée vers l'avant - à une deuxième position dite montée dans laquelle la face avant technique s'étend dans un plan transversal, des bords latéraux de la face avant technique se trouvant sensiblement en regard des extrémités des longerons et la partie du bord supérieur saillant vers l'arrière et/ou latéralement s'étendant au-dessus du plan de la traverse supérieure. io - La face avant technique est montée sur la traverse inférieure par l'intermédiaire de plots portés par la face avant technique coopérant avec des orifices ménagés dans la traverse inférieure. - L'élément saillant comporte un avaloir destiné à coopérer avec un pion porté par la traverse supérieure. 15 - Le pion est une pièce rapportée. D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'exemples de réalisation d'un agencement pour le montage d'une face avant technique de véhicule automobile en référence aux dessins annexés dans lesquels : 20 - La figure 1 est une vue latérale d'une face avant technique après montage sur la structure d'un véhicule. -La figure 2 est une vue latérale de la face avant technique de la figure 1 avant montage. Dans la description qui suit, nous prendrons à titre non limitatif une 25 orientation longitudinale, verticale et transversale indiquée par le trièdre L,V,T de la figure 1 et une orientation d'avant et d'arrière correspondant au sens de déplacement du véhicule. Le véhicule présente une symétrie générale par rapport à un plan longitudinal médian.  According to other features of the invention: - A lower edge of the technical front face is pivotally mounted on the lower cross member about a transverse axis, the technical front face further having an upper edge having at least a portion protruding rearwardly and / or laterally, so that the technical front face passes: - 2 -a first position said unassembled in which it is tilted forward - to a second position said mounted in which the face prior art extends in a transverse plane, the side edges of the technical front face being substantially opposite the ends of the longitudinal members and the portion of the upper edge projecting rearwardly and / or laterally extending above the plane from the top rail. The technical front face is mounted on the lower rail via studs carried by the technical front side cooperating with orifices in the lower rail. - The projecting element comprises a throat for cooperating with a pin carried by the upper rail. 15 - The pawn is a patch. Other characteristics and advantages of the invention will appear on reading the description of exemplary embodiments of an arrangement for mounting a motor vehicle front end with reference to the accompanying drawings in which: FIG. 1 is a side view of a technical front face after mounting on the structure of a vehicle. FIG. 2 is a side view of the technical front face of FIG. 1 before mounting. In the description which follows, we will take nonlimitingly a longitudinal orientation, vertical and transverse indicated by the trihedron L, V, T of Figure 1 and a front and rear orientation corresponding to the direction of movement of the vehicle . The vehicle has general symmetry with respect to a median longitudinal plane.

30 Tel que représenté à la figure 1, une partie avant 10 de structure de véhicule automobile comporte des longerons 12 aux extrémités 14 -3-desquels s'étendent vers le bas des éléments verticaux 16 appelés pendeloques . Les éléments verticaux 16 sont reliés par une traverse inférieure 18. Au dessus des extrémités 14 des longerons 12, s'étend une traverse supérieure 20. Une face avant technique 22 permet de supporter des équipements du véhicule, tels que des câblages, par exemple, mais aussi un module de refroidissement 23. La face avant technique 22 comporte des bords latéraux ainsi qu'un bord supérieur 24 comportant au io moins un élément 26, tel qu'un rebord, par exemple, s'étendant vers l'arrière du véhicule. L'élément 26 peut aussi être saillant latéralement, c'est-à-dire selon la direction transversale. La face avant technique 22 comporte également un bord inférieur 30 monté sur la traverse inférieure 18. A cette fin, le bord inférieur 30 de la face 15 avant technique 22 comporte des plots (non représentés) aptes à coopérer avec des trous (non représentés) ménagés dans la traverse inférieure 18. La face avant technique 22 est montée à pivotement autour d'un axe transversal A sur la traverse inférieure 18 entre une position non 20 montée basculée vers l'avant du véhicule et une position montée dans laquelle la face avant technique 22 est orientée selon un plan transversal, en vis-à-vis de la partie avant 10 de la structure du véhicule. Les plots ont une élasticité suffisante pour permettre un basculement de la face avant technique de l'ordre d'une dizaine de 25 degrés. Lorsque la face avant technique 22 est en position montée, les bords latéraux sont en regard des extrémités 14 des longerons 12 de manière qu'il puissent y être fixés, ce qui donne de la rigidité à la face avant technique 22. La partie 26 du bord supérieur 24, qui est 30 saillante vers l'arrière et/ou latéralement, se situe alors au-dessus du plan horizontal contenant la traverse supérieure 20. Ainsi, le bord supérieur 24 de la face avant technique 22 comporte un avaloir (non représenté) destiné à coopérer avec un pion (non représenté) de la -4 traverse supérieure 20. Dans un autre mode de réalisation, l'avaloir peut être porté par la traverse 20 et le pion par la face avant technique 22. le pion peut être une pièce rapportée. Cet agencement présente donc l'avantage d'optimiser l'utilisation de l'espace au niveau de la partie avant 10 de la structure en profitant de l'espace laissé disponible sur la traverse inférieure 18. Cet agencement présente aussi l'avantage de permettre un montage d'une face avant technique 22 de grandes dimensions, en particulier lorsque sa largeur est supérieure à la distance inter longerons, ou io bien d'une face avant technique 22 présentant sur son bord supérieur 24 un élément 26 saillant vers l'arrière et/ou latéralement. Cet agencement présente également l'avantage de permettre un montage de la face avant technique 22 qui soit compatible avec le montage de la traverse inférieure 18 qui est généralement montée 15 par le dessous selon une direction verticale. Ainsi, il est possible de monter, selon la direction verticale, la traverse inférieure 18 munie de la face avant technique 22 en position basculée, la face avant technique 22 ne risquant pas alors d'entrer en collision avec des éléments de la partie avant 10 de la 20 structure, puis de basculer la face avant technique 22 vers sa position montée.As shown in FIG. 1, a front part 10 of a motor vehicle structure comprises longitudinal members 12 with ends 14 -3 of which downwards vertical elements 16 called pendants extend downwards. The vertical elements 16 are connected by a lower cross member 18. Above the ends 14 of the longitudinal members 12, extends an upper cross member 20. A technical front face 22 can support vehicle equipment, such as wiring, for example, but also a cooling module 23. The technical front 22 has side edges and an upper edge 24 having at least one element 26, such as a flange, for example, extending towards the rear of the vehicle . The element 26 may also project laterally, that is to say in the transverse direction. The technical front face 22 also has a lower edge 30 mounted on the lower cross member 18. For this purpose, the lower edge 30 of the front technical face 22 comprises studs (not shown) able to cooperate with holes (not shown). The front end 22 is pivotally mounted about a transverse axis A on the lower rail 18 between a non-mounted position tilted towards the front of the vehicle and a position mounted in which the front face Technical 22 is oriented in a transverse plane, vis-à-vis the front portion 10 of the vehicle structure. The studs have sufficient elasticity to allow a tilting of the technical front panel of about ten degrees. When the technical front face 22 is in the mounted position, the lateral edges are facing the ends 14 of the longitudinal members 12 so that they can be fixed thereto, which gives rigidity to the technical front face 22. The part 26 of the upper edge 24, which is protruding rearwardly and / or laterally, is then above the horizontal plane containing the upper cross member 20. Thus, the upper edge 24 of the technical front face 22 comprises a drain (not shown ) to cooperate with a pin (not shown) of the upper cross-member 20. In another embodiment, the throat can be carried by the cross member 20 and the peg by the technical front 22. The peg can be a patch. This arrangement therefore has the advantage of optimizing the use of the space at the front portion 10 of the structure taking advantage of the space left available on the lower rail 18. This arrangement also has the advantage of allowing a mounting of a technical front 22 of large dimensions, in particular when its width is greater than the inter-spar distance, or io a technical front face 22 having on its upper edge 24 an element 26 protruding rearwardly and / or laterally. This arrangement also has the advantage of allowing a mounting of the technical front 22 which is compatible with the mounting of the lower cross member 18 which is generally mounted from below in a vertical direction. Thus, it is possible to mount, in the vertical direction, the lower cross member 18 provided with the technical front panel 22 in the tilted position, the technical front face 22 not then likely to collide with elements of the front part 10 of the structure, then tilt the technical front 22 to its mounted position.
