Description

RENFORT INTERNE DE LONGERON DE VEHICULE AUTOMOBILE INTEGRABLE AU SEIN D'UNE BASE ROULANTE. LONGERON INTERNAL REINFORCEMENT OF INTEGRABLE MOTOR VEHICLE WITHIN A ROLLING BASE.
L' invention concerne un renfort interne de longeron de véhicule automobile.The invention relates to an internal reinforcement of a motor vehicle spar.
Un renfort connu de ce type repéré par 1 sur la figure 1, présente une section transversale dont les dimensions augmentent en direction de l'extrémité arrière 2 du renfort 1 pour définir une embase 3 servant d' appui à un montant d'encadrement 4 d'une porte latérale arrière du véhicule.A known reinforcement of this type, indicated by 1 in FIG. 1, has a cross-section whose dimensions increase in the direction of the rear end 2 of the reinforcement 1 to define a base 3 serving to support a frame upright 4d. a rear side door of the vehicle.
Dans les procédés de fabrication des véhicules automobiles actuels, on s'efforce de former une entité communément nommée « base véhicule », telle qu'une base roulante qui comprend par exemple le châssis, les traverses ou encore les passages de roues du véhicule, commune à tous les véhicules d'une même gamme présentant pourtant des silhouettes différentes, telles que des cabriolets, des berlines, ou des monospaces. Le concept de « base roulante » permet ainsi de diminuer les coûts, les temps d'assemblage de ces véhicules et d'utiliser les moyens industriels permettant de les fabriquer pour les différentes déclinaisons de véhicule résultant des évolutions commerciales. Toutefois, le renfort susmentionné n'est pas intégrable au sein d'une « base roulante » car ses dimensions et sa forme changent d'une silhouette de véhicule à une autre et requiert ainsi pour sa fabrication des procédés particuliers de découpage et d'emboutissage de la feuille de tôlerie le constituant pour chaque silhouette de véhicule développée.In current motor vehicle manufacturing processes, an attempt is made to form an entity commonly called "vehicle base", such as a rolling base which comprises for example the chassis, the sleepers or the wheel wells of the vehicle, common to all vehicles in the same range with different silhouettes, such as convertibles, sedans, or minivans. The concept of "rolling base" thus makes it possible to reduce the costs, the assembly times of these vehicles and to use the industrial means making it possible for the different vehicle versions resulting from commercial evolutions. However, the aforementioned reinforcement is not integrable within a "rolling base" because its dimensions and shape change from one vehicle silhouette to another and thus requires for its manufacture special cutting and stamping processes the sheet metal sheet constituting it for each developed vehicle silhouette.
L'invention vise à palier cet inconvénient. A cet effet, l'invention concerne un renfort interne de longeron de véhicule automobile, ayant une forme générale longiligne et une section transversale dont les dimensions augmentent en direction de l'une des extrémités du renfort pour définir une embase d' appui pour un montant d'encadrement d'une porte latérale du véhicule . Selon l'invention, le renfort comprend un profilé principal et une garniture rapportée à une extrémité du profilé pour former avec cette extrémité l'embase du renfort, cette garniture ayant une section transversale de plus grandes dimensions que la section transversale du profilé du renfort et un côté arrière s 'étendant dans le prolongement du bord arrière du profilé.The invention aims to overcome this disadvantage. For this purpose, the invention relates to an internal reinforcement of a motor vehicle spar, having a generally elongate shape and a cross section whose dimensions increase towards one of the ends of the reinforcement to define a support base for a frame amount of a side door of the vehicle. According to the invention, the reinforcement comprises a main section and a lining attached to one end of the profile to form with this end the base of the reinforcement, this liner having a larger cross-sectional area than the cross section of the reinforcing section and a rear side extending in the extension of the rear edge of the profile.
Selon une autre caractéristique, le bord arrière du profilé est sensiblement vertical.According to another characteristic, the rear edge of the profile is substantially vertical.
Selon une autre caractéristique, la garniture comprend une partie fixée par soudage transversalement relativement au profilé.According to another characteristic, the lining comprises a portion fixed by welding transversely relative to the profile.
Selon encore une autre caractéristique, la partie de fixation de la garniture s'étend sur toute la hauteur du profilé. Avantageusement, le profilé présente une section transversale de forme générale constante.According to yet another characteristic, the fastening portion of the liner extends over the entire height of the profile. Advantageously, the profile has a cross section of generally constant shape.
L' invention concerne également la base roulante comprenant le profilé du renfort ci-dessus.The invention also relates to the rolling base comprising the profile of the reinforcement above.
L' invention est également relative à un véhicule automobile comprenant la base roulante précitée, dans lequel la garniture est interposée entre le profilé de la base roulante et le montant d'encadrement et fixée dans cette position de façon à constituer le renfort du véhicule . L'invention sera mieux comprise, et d'autres caractéristiques, et avantages de celle-ci apparaîtront au cours de la description suivante, faite en référence aux figures annexées, parmi lesquelles : la figure 1 précitée illustre un renfort d'un longeron de type connu représenté au sein de la carrosserie d'un véhicule automobile ; la figure 2 est une vue en perspective avec arrachement d'un renfort de longeron selon l'invention ;The invention also relates to a motor vehicle comprising the aforementioned rolling base, wherein the lining is interposed between the section of the rolling base and the frame amount and fixed in this position so as to form the reinforcement of the vehicle. The invention will be better understood, and other features and advantages thereof will become apparent from the following description, with reference to the appended figures, among which: Figure 1 above illustrates a reinforcement of a spar known type shown in the body of a motor vehicle; Figure 2 is a cutaway perspective view of a spar reinforcement according to the invention;
- la figure 3 est une vue similaire à la figure 1 avec le renfort de la figure 2.FIG. 3 is a view similar to FIG. 1 with the reinforcement of FIG.
Dans la description qui va suivre, les notions « avant » et « arrière » s'entendent dans le sens classique de l'orientation avant-arrière d'un véhicule automobile .In the description that follows, the concepts "before" and "back" are in the classic sense of the front-rear orientation of a motor vehicle.
Le renfort interne 6 de longeron représenté sur la figure 2 sert de rigidification de la structure du véhicule en cas de choc latéral subi par ce dernier. Comme visible sur la figure 3, ce renfort 6 est fixé à une partie basse de la carrosserie du véhicule située sous les ouvertures latérales avant et arrière 7, 8 de cette carrosserie destinées à être fermées par les portes latérales correspondantes du véhicule et entre deux passages latéraux de roues du véhicule.The internal reinforcement 6 of spar shown in Figure 2 serves to stiffen the vehicle structure in case of side impact suffered by the latter. As can be seen in FIG. 3, this reinforcement 6 is fixed to a lower part of the vehicle body located under the front and rear side openings 7, 8 of this bodywork intended to be closed by the corresponding lateral doors of the vehicle and between two passages. lateral wheels of the vehicle.
Ce renfort 6 comprend ainsi, lorsque le véhicule dans lequel il est intégré comporte par exemple quatre portes latérales, une partie centrale 9 venant à être située à l'aplomb du montant latéral central 11 de ce véhicule, par rapport auquel la porte arrière du véhicule est articulée, et une extrémité arrière 12 coïncidant avec le montant arrière 13 du véhicule, contre lequel ladite porte vient en appui lorsqu'elle ferme l'ouverture arrière 8. Plus précisément, ce renfort 6 comprend une partie longiligne 14 qui constitue une poutre latérale au sein du véhicule fixée au châssis de ce véhicule, et une embase 16 définie par l'extrémité arrière 12 du renfort 6. Cette embase 16 présente une section transversale dont les dimensions verticales augmentent en direction du bord arrière libre 17 du renfort et comprend ainsi un bord inférieur 18 sensiblement constant et un bord supérieur 19 divergeant relativement au bord inférieur 18. L'embase 16 comprend encore une portion de réception 21 du montant arrière 13 du véhicule longeant son bord supérieur divergeant 19 et qui est de forme complémentaire du pied 22 du montant arrière 13. Selon l'invention, le renfort 6 comprend un profilé principal 23 et une garniture 24 rapportée à l'extrémité arrière 26 du profilé 23 et qui présente une section transversale supérieure à celle de cette extrémité 26 de profilé . Plus précisément, comme visible sur la figure 2, le profilé 23 forme la poutre de rigidification 14 et présente ainsi une forme générale longiligne et définit le bord arrière libre 17 du renfort 6 ainsi que ses bords inférieur et supérieur rectilignes 18, 29. Etant donné la fonction unique de rigidification de ce profilé 23, il est à noter que sa forme varie peu ou pas dans une même gamme de véhicules.This reinforcement 6 thus comprises, when the vehicle in which it is integrated includes for example four side doors, a central portion 9 to be located in line with the central lateral upright 11 of the vehicle, with respect to which the rear door of the vehicle is articulated, and a rear end 12 coinciding with the rear upright 13 of the vehicle, against which said door bears when it closes the rear opening 8. More specifically, this reinforcement 6 comprises an elongate portion 14 which constitutes a lateral beam in the vehicle attached to the chassis of this vehicle, and a base 16 defined by the rear end 12 of the reinforcement 6. This base 16 has a cross section whose vertical dimensions increase towards the free rear edge 17 of the reinforcement and thus comprises a substantially constant lower edge 18 and an upper edge 19 diverging relative to the lower edge 18. The base 16 further comprises a portion receiving 21 of the rear upright 13 of the vehicle along its diverging upper edge 19 and which is of complementary shape of the foot 22 of the rear pillar 13. According to the invention, the reinforcement 6 comprises a main section 23 and a trim 24 attached to the rear end 26 of the section 23 and which has a cross section greater than that of this end 26 of section. More precisely, as can be seen in FIG. 2, the profile 23 forms the stiffening beam 14 and thus has a generally elongate shape and defines the free rear edge 17 of the reinforcement 6 as well as its rectilinear lower and upper edges 18, 29. the unique stiffening function of this profile 23, it should be noted that its shape varies little or not in the same range of vehicles.
De la sorte, le profilé 23 du renfort de l'invention 6 définit une pièce standard, c'est-à-dire commune aux différents types de véhicules (berlines, monospaces, cabriolets) d'une même gamme.In this way, the profile 23 of the reinforcement of the invention 6 defines a standard part, that is to say, common to different types of vehicles (sedans, minivans, cabriolets) of the same range.
D'autre part, la garniture 24 comprend une partie fixée 24a par exemple par soudage électrique sur toute la largeur de la paroi intérieure 27 de l'extrémité arrière 26 du profilé 23.On the other hand, the lining 24 comprises a fixed portion 24a for example by electrical welding over the entire width of the inner wall 27 of the rear end 26 of the section 23.
Cette partie de fixation 24a présente avantageusement une forme complémentaire de l'extrémité arrière 26 du profilé 23 et est prolongée par une partie de la garniture formant une ailette en saillie au-dessus du profilé, ailette par exemple de forme sensiblement triangulaire 24b, dont la base 28 coïncide avec le bord supérieur 29 du profilé 23, dont un côté arrière 31 s'étend dans le prolongement du bord arrière vertical du profilé 23 qui constitue le bord arrière libre 17 du renfort 6, et dont un côté d'appui 32 s'étend depuis une extrémité supérieure 33 du côté arrière 31 jusqu'au bord supérieur 29 du profilé 23. Ainsi la garniture 24 recouvre, sur sensiblement toute sa longueur, l'extrémité correspondante du profilé 23 de façon à assurer une bonne solidarisation des deux pièces.This fixing portion 24a advantageously has a shape complementary to the rear end 26 of the section 23 and is extended by a portion of the lining forming a fin projecting above of the profile, for example a wing of substantially triangular shape 24b, whose base 28 coincides with the upper edge 29 of the profile 23, a rear side 31 of which extends in the extension of the vertical rear edge of the profile 23 which constitutes the free rear edge 17 of the reinforcement 6, and a support side 32 extends from an upper end 33 of the rear side 31 to the upper edge 29 of the profile 23. Thus the seal 24 covers, over substantially its entire length, the end corresponding profile 23 so as to ensure good bonding of the two parts.
Ce côté d' appui 32 définit encore une arête curviligne concave constituant le bord supérieur divergeant 19 de l'embase 16, et une arête sensiblement rectiligne 34 reliant l'extrémité de l'arête curviligne 19 opposée au profilé 23 à l'extrémité du côté arrière 31 de l'ailette 24b de la garniture 24.This support side 32 further defines a concave curvilinear edge constituting the diverging upper edge 19 of the base 16, and a substantially rectilinear edge 34 connecting the end of the curvilinear edge 19 opposite the profile 23 at the end of the side. rear 31 of the fin 24b of the seal 24.
La garniture 24 définit une pièce de petites dimensions, rapportée à l'extrémité 26 du profilé 23 et dont la forme peut être adaptée en fonction de la silhouette choisie du véhicule.The liner 24 defines a small part, attached to the end 26 of the profile 23 and whose shape can be adapted according to the chosen silhouette of the vehicle.
Ainsi, le profilé standard 23 du renfort 6 peut être intégré au sein d'une « base véhicule » telle qu'une base dite roulante, c'est-à-dire qui comprend par exemple les traverses, le plancher, les passages de roue, les pare-boue, les longerons extérieurs et le châssis du véhicule et qui sera identique pour différentes silhouettes de véhicule.Thus, the standard section 23 of the reinforcement 6 can be integrated within a "vehicle base" such as a so-called rolling base, that is to say which comprises, for example, sleepers, the floor, the wheel wells , the mudguards, the outer spars and the chassis of the vehicle and which will be identical for different vehicle silhouettes.
Seule la garniture 24 du renfort 6 devra être sera modifiée en fonction de la silhouette choisie du véhicule, c'est-à-dire en fonction principalement de la forme des portes et des montants arrières latéraux définis pour un style particulier du véhicule. L' invention telle que décrite ci-dessus apporte différents avantages parmi lesquels : la possibilité d'augmenter le nombre d'éléments du véhicule pouvant intégrer une « base véhicule » et pouvant ainsi être fabriqués à grande échelle pour différentes gammes de véhicule, la possibilité de pouvoir tout de même faire varier les silhouettes des véhicules des différentes gammes, par l'adaptation de la forme de la garniture rapportée aux portes et aux montants arrière latéraux du véhicule, la diminution des coûts et du temps de fabrication, et la baisse du nombre d'outils nécessaires à la fabrication de véhicules de silhouettes différentes. Only the lining 24 of the reinforcement 6 will have to be modified according to the chosen silhouette of the vehicle, that is to say, mainly depending on the shape of the doors and the rear side uprights defined for a particular style of the vehicle. The invention as described above brings various advantages among which: the possibility of increasing the number of elements of the vehicle that can integrate a "vehicle base" and can thus be manufactured on a large scale for different ranges of vehicle, the possibility to be able to vary the silhouettes of the vehicles of the different ranges, by adapting the shape of the lining to the doors and rear side posts of the vehicle, reducing costs and manufacturing time, and reducing the number of tools needed to make vehicles with different silhouettes.
