Description

CAISSE DE VEHICULE AUTOMOBILE ET PROCEDE DE REALISATION AUTOMOTIVE VEHICLE FUND AND METHOD OF MAKING THE SAME
CORRESPONDANT.CORRESPONDING.
L'invention concerne une caisse de véhicule automobile ainsi qu'un procédé de réalisation correspondant.The invention relates to a motor vehicle body and a corresponding embodiment method.
Une caisse classique comporte deux encadrements de porte latérale avant, chaque encadrement étant délimité par un pied milieu, un pied avant, un montant de baie et un longeron de soubassement. Une partie avant de la caisse s'étend en outre depuis les pieds milieux, ladite partie avant comprenant notamment des passages de roue.A conventional body has two front side door frames, each frame being delimited by a foot, a front foot, a bay jamb and a base beam. A front portion of the body further extends from the middle legs, said front part including wheel arches.
Les longerons de soubassement et les parties inférieures des pieds avants sont reliés entre eux par l'intermédiaire d'un plancher, s'étendant sensiblement horizontalement. En outre, les pieds avant sont reliés l'un à l'autre par un tablier dit inférieur et un tablier dit supérieur. Dans la suite de la description, on s'intéressera plus particulièrement au tablier inférieur, qu'on nommera ci-après simplement tablier.The base rails and the lower parts of the front legs are interconnected via a floor, extending substantially horizontally. In addition, the front feet are connected to each other by a deck called lower and apron said superior. In the remainder of the description, we will focus more particularly on the lower deck, which will be hereinafter simply apron.
Le tablier comporte deux bords latéraux, fixés respectivement sur chaque pied avant.The apron has two lateral edges, respectively fixed on each front leg.
Afin de diminuer le nombre de pièces nécessaires à la fabrication de plusieurs types de véhicule, il est nécessaire de pouvoir utiliser le maximum de pièces communes aux différents types.In order to reduce the number of parts necessary for the manufacture of several types of vehicle, it is necessary to be able to use the maximum of common parts of the different types.
Ceci permet notamment de réduire les coûts de fabrication d'un véhicule.This in particular reduces the manufacturing costs of a vehicle.
En ce qui concerne en particulier la caisse, il est nécessaire de pouvoir adapter sa largeur en changeant le moins possible de composants de celle-ci.As regards in particular the body, it is necessary to be able to adapt its width by changing the least possible components of it.
Comme cela est représenté aux figures 1 et 2 annexées, une caisse classique de véhicule s'étend selon un axe longitudinal A entre une partie arrière 1 et une partie avant 2 destinée à accueillir un bloc moteur. Le sens transversal est défini par l'axe B, s'étendant perpendiculairement à l'axeAs shown in Figures 1 and 2 attached, a conventional vehicle body extends along a longitudinal axis A between a rear portion 1 and a front portion 2 for receiving a motor unit. The transverse direction is defined by the axis B, extending perpendicular to the axis
A.AT.
La caisse comporte un plancher formé par un plancher droit (non représenté) et un plancher gauche 3 s'étendant chacun sensiblement horizontalement et présentant une face supérieure 4 ainsi qu'une face inférieure 5. La caisse comporte en outre deux longerons de soubassement 6, disposés de chaque côté du plancher. Chaque longeron 6 présente une face inférieure 7 (figure 2) s'étendant sensiblement horizontalement et une face intérieure 8 (figure 1 ), c'est-à-dire tournée vers le longeron opposé ou vers l'habitacle de la caisse, s'étendant sensiblement verticalement. Chaque longeron 6 est prolongé à son extrémité avant par un pied avant 9, respectivement droit et gauche.The box comprises a floor formed by a straight floor (not shown) and a left floor 3 each extending substantially horizontally and having an upper face 4 and a lower face 5. The box further comprises two underbody 6, arranged on each side of the floor. Each spar 6 has a lower face 7 (Figure 2) extending substantially horizontally and an inner face 8 (Figure 1), that is to say facing the opposite spar or to the cockpit of the body, s' extending substantially vertically. Each spar 6 is extended at its front end by a front leg 9, respectively right and left.
Chaque pied avant comporte une première partie 10 s'étendant sensiblement horizontalement dans le prolongement du longeron 6 de soubassement correspondant et une seconde partie 1 1 s'étendant vers le haut, reliées l'une à l'autre par une zone courbe 12.Each front foot has a first portion 10 extending substantially horizontally in the extension of the corresponding underbody 6 and a second portion 1 1 extending upwards, connected to each other by a curved zone 12.
La première partie 10 comporte une face inférieure 13 (figure 2) s'étendant dans le plan de la face inférieure 7 du longeron correspondant 6. Chaque pied avant 9 comporte en outre une face intérieure 14 (figure 1 ) s'étendant dans le plan de la face intérieure 8 du longeron correspondant 6.The first part 10 has a lower face 13 (FIG. 2) extending in the plane of the lower face 7 of the corresponding spar 6. Each front foot 9 also has an inner face 14 (FIG. 1) extending in the plane of the inner face 8 of the corresponding spar 6.
La seconde partie 1 1 de chaque pied avant 9 comporte une face 15 tournée vers l'avant et présentant une zone 16, située du côté de la face intérieure, inclinée de l'avant vers l'arrière et de l'intérieur vers l'extérieur.The second portion 1 1 of each front leg 9 has a face 15 facing forward and having an area 16, located on the side of the inner face, inclined from the front to the rear and from the inside towards the outside.
Les pieds avant 9 gauche et droit sont reliés l'un à l'autre par l'intermédiaire d'un tablier dit inférieur 17, ci-après appelé simplement tablier. Le tablier comporte un bord latéral gauche 18 et un bord latéral droit 19, une extrémité supérieure 20 et une extrémité inférieure 21.The front feet 9 left and right are connected to each other via a so-called lower apron 17, hereinafter simply called apron. The apron has a left lateral edge 18 and a right lateral edge 19, an upper end 20 and a lower end 21.
L'extrémité inférieure 21 du tablier 17 est fixée à l'avant du plancher 3, plus particulièrement sur la face supérieure 4 de celui-ci. On s'attachera plus particulièrement aux zones d'accostage ou de liaison entre le plancher 3 et le longeron de soubassement 6 correspondant et entre le tablier 17 et le pied avant 9 correspondant.The lower end 21 of the deck 17 is fixed to the front of the floor 3, more particularly on the upper face 4 thereof. Particular attention will be paid to the docking or connecting zones between the floor 3 and the corresponding underbody 6 and between the deck 17 and the corresponding front foot 9.
Dans la suite de la description, seule la partie gauche de la caisse sera décrite. La caisse étant globalement symétrique, des zones d'accostage similaires étant prévues dans la partie droite de la caisse.In the remainder of the description, only the left side of the box will be described. The body being generally symmetrical, similar landing areas being provided in the right part of the body.
Le bord gauche du plancher gauche 3 comporte une lèvre 22 s'étendant horizontalement.The left edge of the left floor 3 has a lip 22 extending horizontally.
Comme cela est mieux visible à la figure 2, la lèvre précitée vient en appui contre la face inférieure 7 du longeron gauche 6 et contre la face inférieure 13 du pied avant gauche 9. En fonction du type de véhicule à fabriquer, c'est-à-dire en fonction de la largeur de la caisse, l'écartement entre les longerons 6 et l'écartement entre les pieds avants 9 doit être modifié. Pour cela, il est possible de faire glisser la lèvre 22 sur les faces inférieures 7, 13, tout en conservant un chevauchement suffisant de la lèvre 22 sur celles-ci. Une fois le plancher 3, le longeron de soubassement 6 et le pied avant 9 correctement positionnés, des points de soudures électriques peuvent être réalisés dans la zone de chevauchement afin de fixer les différents composants les uns par rapport aux autres. Le bord gauche 18 du tablier 17 comporte, dans sa partie inférieure, une première lèvre 23 s'étendant sensiblement verticalement vers le haut, venant en butée contre la paroi intérieure 14 du pied avant 9.As can be seen more clearly in FIG. 2, the abovementioned lip bears against the lower face 7 of the left spar 6 and against the lower face 13 of the left front foot 9. Depending on the type of vehicle to be manufactured, that is to say according to the width of the body, the spacing between the longitudinal members 6 and the spacing between the front legs 9 must be modified. For this, it is possible to slide the lip 22 on the lower faces 7, 13, while maintaining sufficient overlap of the lip 22 thereon. Once the floor 3, the basement spar 6 and the front foot 9 correctly positioned, electric weld points can be made in the overlap area to fix the various components relative to each other. The left edge 18 of the apron 17 has, in its lower part, a first lip 23 extending substantially vertically upwards, abutting against the inner wall 14 of the front foot 9.
Le bord gauche du tablier comporte également, dans sa partie supérieure, une seconde lèvre 24 s'étendant de manière inclinée vers l'arrière et vers l'extérieur. Ladite lèvre 24 vient en appui contre la zone inclinée 16 du pied avant gauche 9.The left edge of the apron also has, in its upper part, a second lip 24 extending inclined towards the rear and towards the outside. Said lip 24 bears against the inclined zone 16 of the left front foot 9.
Le tablier 17 est fixé au pied avant gauche 9 au niveau de la première et de la seconde lèvres 23, 24, par l'intermédiaire de points de soudure. II n'est pas possible d'ajuster, avant la réalisation de la soudure, la position, selon le sens transversal, du tablier 17 vis-à-vis du pied avant gauche 9.The apron 17 is fixed to the left front foot 9 at the first and second lips 23, 24, via welding points. It is not possible to adjust, before the welding is made, the position, in the transverse direction, of the apron 17 with respect to the left front foot 9.
En effet, les zones d'accostage formées par les premières et seconde lèvres 23, 24 n'autorisent pas, du fait de leur structure et de leur position, de débattement vis-à-vis des faces correspondantes du pied avant 9.Indeed, the docking areas formed by the first and second lips 23, 24 do not allow, because of their structure and their position, clearance vis-à-vis the corresponding faces of the front foot 9.
Il est ainsi nécessaire de disposer d'un tablier 17 pour chaque largeur de caisse.It is thus necessary to have an apron 17 for each body width.
Il est donc indispensable de disposer d'un type de tablier pour chaque type de véhicule nécessitant un écartement différent entre les longerons et/ou les pieds avant. Ceci entraîne une augmentation des coûts de fabrication de la caisse ainsi qu'une gestion des stocks adaptée.It is therefore essential to have a type of apron for each type of vehicle requiring a different spacing between the longitudinal members and / or the front feet. This leads to an increase in the cost of manufacturing the box as well as an appropriate inventory management.
L'invention vise à remédier à cet inconvénient en proposant une caisse.The invention aims to remedy this drawback by proposing a box.
A cet effet, l'invention concerne une caisse de véhicule automobile s'étendant selon un axe longitudinal entre une partie arrière et une partie avant, comportant au moins un pied avant et au moins un tablier monté sur le pied avant, caractérisée en ce qu'elle comprend des moyens d'ajustement de la position du tablier par rapport au pied avant, selon un axe transversal.For this purpose, the invention relates to a motor vehicle body extending along a longitudinal axis between a rear portion and a front portion, comprising at least one front foot and at least one deck mounted on the foot front, characterized in that it comprises means for adjusting the position of the deck relative to the front foot, along a transverse axis.
Les moyens d'ajustement permettent ainsi d'utiliser un même tablier pour plusieurs largeurs de caisse, c'est-à-dire pour plusieurs types de véhicule. Le nombre de pièces nécessaires à la réalisation de plusieurs modèles distincts de véhicule est donc réduit.The adjustment means thus make it possible to use the same apron for several body widths, that is to say for several types of vehicle. The number of parts needed to make several different models of vehicle is reduced.
Selon une caractéristique de l'invention, le tablier comprend un bord latéral équipé d'une lèvre de positionnement montée sur une face du pied avant, ladite lèvre étant destinée à régler la position relative du tablier par rapport à ladite face, suivant l'axe transversal.According to one characteristic of the invention, the apron comprises a lateral edge equipped with a positioning lip mounted on one face of the front foot, said lip being intended to adjust the relative position of the apron with respect to said face, along the axis transverse.
Le glissement de la lèvre le long de la face du pied avant permet d'ajuster le positionnement du tablier vis-à-vis du pied avant. La largeur de la lèvre est déterminée en fonction du débattement à autoriser, une partie de la lèvre devant nécessairement être en appui contre la face précitée, de manière à pouvoir réaliser la fixation du tablier sur le pied avant, par exemple par soudure.The sliding of the lip along the face of the front foot makes it possible to adjust the positioning of the apron vis-à-vis the front foot. The width of the lip is determined according to the clearance to be allowed, a portion of the lip must necessarily bear against the aforementioned face, so as to achieve the fixing of the deck on the front foot, for example by welding.
Avantageusement, la largeur de la lèvre est comprise entre 40 et 50 mm.Advantageously, the width of the lip is between 40 and 50 mm.
Selon une possibilité de l'invention, le pied avant est relié à au moins un longeron de soubassement, au moins un plancher étant monté sur ledit longeron de soubassement, le tablier étant en outre monté sur le plancher, au niveau d'une extrémité inférieure du tablier.According to a possibility of the invention, the front foot is connected to at least one underside beam, at least one floor being mounted on said underbody spar, the deck being further mounted on the floor, at a lower end apron.
Préférentiellement, la caisse comporte un organe de liaison relié d'une part à un brancard et d'autre part au longeron de soubassement par l'intermédiaire du pied avant.Preferably, the body comprises a connecting member connected firstly to a stretcher and secondly to the underside beam through the front foot.
Selon une caractéristique de l'invention, l'organe de liaison comporte un bord latéral externe, tourné du côté du pied avant, fixé à un organe intermédiaire, lui-même monté sur le pied avant.According to a characteristic of the invention, the connecting member comprises an external lateral edge, turned on the side of the front foot, fixed to an intermediate member, itself mounted on the front foot.
La largeur de l'organe intermédiaire, c'est-à-dire la dimension de celui-ci suivant le sens transversal, est fonction du type de caisse à réaliser. En effet, plus les longerons et les pieds avant sont écartés, c'est-à-dire plus la caisse est large, plus la largeur du profilé sera importante.The width of the intermediate member, that is to say the dimension thereof in the transverse direction, depends on the type of box to achieve. Indeed, the longer the beams and the front legs are spread, that is to say the larger the body is large, the width of the profile will be important.
Avantageusement, l'organe intermédiaire présente une forme générale en U et comporte une première branche fixée à l'organe de liaison ainsi qu'une seconde branche fixée au pied avant. Selon une possibilité de l'invention, le plancher comporte des moyens d'ajustement de la position du plancher vis-à-vis du longeron de soubassement, selon l'axe transversal.Advantageously, the intermediate member has a generally U-shaped and comprises a first branch attached to the connecting member and a second branch attached to the front foot. According to a possibility of the invention, the floor comprises means for adjusting the position of the floor vis-à-vis the underside of the underframe along the transverse axis.
Ainsi, en fonction de la largeur de la caisse, il est possible de faire varier la position du plancher vis-à-vis de chaque longeron de soubassement.Thus, depending on the width of the body, it is possible to vary the position of the floor vis-à-vis each underside beam.
Préférentiellement, la caisse comporte un premier et un second pieds avants, sur lesquels est monté le tablier, respectivement au niveau d'un premier et d'un second bords de celui-ci, au moins l'un des bords du tablier étant équipé de moyens d'ajustement de la position du bord correspondant du tablier vis-à-vis du pied avant correspondant, selon l'axe transversal.Preferably, the box comprises a first and a second front legs, on which the deck is mounted, respectively at a first and a second edge thereof, at least one of the edges of the deck being equipped with means for adjusting the position of the corresponding edge of the apron vis-à-vis the corresponding front foot, along the transverse axis.
L'invention concerne également un véhicule automobile caractérisé en ce qu'il comporte une caisse selon l'invention.The invention also relates to a motor vehicle characterized in that it comprises a box according to the invention.
L'invention concerne en outre un procédé de réalisation d'une caisse automobile s'étendant selon un axe longitudinal entre une partie arrière et une partie avant, et comportant au moins un pied avant et au moins un tablier, ledit procédé comprenant les étapes suivantes :The invention further relates to a method of producing a car body extending along a longitudinal axis between a rear portion and a front portion, and comprising at least one front foot and at least one apron, said method comprising the following steps :
- disposer le tablier sur le pied avant,- arrange the apron on the front foot,
- ajuster la position du tablier par rapport au pied avant, suivant le sens transversal, en fonction du type de caisse à réaliser, - fixer le tablier au pied avant, par exemple par soudure.- adjust the position of the deck relative to the front foot, in the transverse direction, depending on the type of body to be made, - fix the deck to the front foot, for example by welding.
De préférence, l'étape visant à fixer le tablier au pied avant consiste :Preferably, the step of fixing the apron to the front foot consists of:
- à placer puis fixer un organe de liaison sous le tablier,- to place and then fix a connecting member under the apron,
- à placer puis fixer un organe intermédiaire entre que l'organe de liaison et le pied avant.- To place and fix an intermediate member between the connecting member and the front foot.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence aux dessins schématiques annexés représentant, à titre d'exemple, une forme de réalisation de cette caisse de véhicule automobile . Figures 3 à 5 sont des vues illustrant l'invention ;Anyway, the invention will be better understood from the following description with reference to the accompanying schematic drawings representing, by way of example, an embodiment of this body of a motor vehicle. Figures 3 to 5 are views illustrating the invention;
Figure 3 est une vue en perspective et de dessous de la caisse d'un véhicule, représentant uniquement la zone d'accostage du tablier sur le pied avant gauche ;Figure 3 is a perspective view from below of the body of a vehicle, showing only the docking area of the apron on the front left foot;
Figure 4 est une vue en coupe selon un plan transversal représentant la zone d'accostage du tablier et de l'organe de liaison sur le pied avant ; Figure 5 est une vue correspondant à la figure 3, représentant une caisse avec un positionnement différent du tablier vis-à-vis du pied avant.Figure 4 is a sectional view along a transverse plane showing the docking area of the deck and the connecting member on the front foot; Figure 5 is a view corresponding to Figure 3, showing a box with a different positioning of the deck vis-à-vis the front foot.
Comme cela est visible aux figures 3 et 4, un organe de liaison 25, se présentant sous la forme d'une pièce en tôle coudée, est fixé sur le tablier 17, le plancher 3 et le pied avant 9. L'organe de liaison 25 permet la fixation d'un brancard, non représenté.As can be seen in FIGS. 3 and 4, a connecting member 25, in the form of a bent sheet metal part, is fixed on the apron 17, the floor 3 and the front foot 9. The connecting member 25 allows the attachment of a stretcher, not shown.
L'organe de liaison 25 présente plus particulièrement une zone supérieure 26 fixée sur le tablier 17, une zone inférieure 27 fixée sur le plancher 3 et un bord 28, tourné du côté du pied avant correspondant et apte à être fixé sur celui-ci.The connecting member 25 has more particularly an upper zone 26 fixed on the apron 17, a lower zone 27 fixed on the floor 3 and an edge 28, turned on the side of the front foot corresponding and adapted to be fixed thereon.
Les éléments présentant la même fonction que ceux décrit précédemment dans l'état de la technique antérieur ont été désignés par les mêmes références. Les éléments de la caisse selon l'invention qui sont similaires ou identiques à ceux décrits précédemment ne sont pas décrits ci- après. La description qui suit vise principalement à souligner les différences entre l'invention et l'art antérieur.The elements having the same function as those described previously in the state of the prior art have been designated by the same references. The elements of the box according to the invention which are similar or identical to those described above are not described below. The following description is primarily intended to highlight the differences between the invention and the prior art.
Comme cela est visible notamment à la figure 3, chaque bord gauche 18 du tablier est équipé d'une lèvre 29 s'étendant transversalement, suivant une courbure conforme à celle des faces inférieures et avant 13, 15 du pied avant.As can be seen in particular in FIG. 3, each left edge 18 of the apron is equipped with a lip 29 extending transversely, with a curvature conforming to that of the lower and front faces 13, 15 of the front foot.
Lesdites faces 13, 15 du pied avant s'étendant également transversalement, selon respectivement des plans sensiblement horizontal et vertical. De manière avantageuse, le déplacement de la lèvre 29 vis-à-vis du pied avant 9 peut être effectué afin d'ajuster la position du tablier 17 par rapport au pied avant 9 correspondant.Said faces 13, 15 of the front foot also extending transversely, respectively in substantially horizontal and vertical planes. Advantageously, the displacement of the lip 29 vis-à-vis the front foot 9 can be performed to adjust the position of the deck 17 relative to the front foot 9 corresponding.
Une fois la position ajustée en fonction du type de caisse à réaliser, la lèvre 29 peut être fixée par soudage au pied avant 9.Once the position adjusted according to the type of box to achieve, the lip 29 can be fixed by welding to the front foot 9.
La largeur de la lèvre est comprise entre 40 et 50 mm, de préférence 45 mm de manière à pouvoir obtenir un débattement suffisamment de celle-ci sur le pied avant, 20 mm restant en outre dédiés à la soudure.The width of the lip is between 40 and 50 mm, preferably 45 mm so as to obtain a sufficient deflection thereof on the front foot, 20 mm remaining further dedicated to the weld.
De la même manière que précédemment, seul le pied gauche 9 est représenté, la caisse présentant une structure similaire ou identique au niveau du pied avant droit.In the same manner as above, only the left foot 9 is shown, the body having a similar or identical structure at the right front foot.
Comme cela apparaît notamment à la figure 14, le bord gauche 28 de l'organe de liaison 25 est fixé, non plus directement sur le pied avant 9, mais sur un organe intermédiaire 30, lui-même fixé sur le pied avant 9. Plus particulièrement, le bord gauche 28 de l'organe de liaison 25 présente une aile s'étendant sensiblement verticalement et vers le bas. L'organe intermédiaire 30 se présente sous la forme d'un profilé en U ouvert sur l'extérieur du véhicule qui est destiné à former une butée d'appui à une roue adjacente en cas de choc frontal du véhicule contre un obstacle. L'organe intermédiaire 30 comporte une base 31 à partir de laquelle s'étendent sensiblement longitudinalement au véhicule, une branche interne 32 et une branche externe 33. La branche interne 32 est fixée à l'aile correspondante 28 de l'organe de liaison 25 et la branche externe 33 est fixée sur le pied avant 9. Ainsi, comme cela apparaît aux figures 3 et 5, en fonction du type de caisse à réaliser, c'est-à-dire en fonction du positionnement du tablier 17 et de l'organe de liaison 25 qui lui est rattaché vis-à-vis du pied avant 9, la largeur de l'organe intermédiaire 30, plus particulièrement la largeur de la base 31 , varie de façon à assurer la liaison entre l'organe de liaison et le pied avant. De cette manière, il est possible d'utiliser un tablier 17, un organe de liaison 2 5 et un pied avant 9 standards pour différentes largeurs de caisse, c'est-à-dire pour différents types de véhicules, seul l'organe intermédiaire 30 devant être changé.As appears in particular in Figure 14, the left edge 28 of the connecting member 25 is fixed, either directly to the front foot 9, but on an intermediate member 30, itself fixed on the front foot 9. More particularly, the left edge 28 of the connecting member 25 has a flange extending substantially vertically and downwardly. The intermediate member 30 is in the form of a U-shaped profile open on the outside of the vehicle which is intended to form a bearing abutment to an adjacent wheel in the event of a frontal impact of the vehicle against an obstacle. The intermediate member 30 comprises a base 31 from which extend substantially longitudinally to the vehicle, an inner leg 32 and an outer leg 33. The inner leg 32 is fixed to the corresponding flange 28 of the connecting member 25 and the outer branch 33 is fixed on the front foot 9. Thus, as shown in Figures 3 and 5, depending on the type of box to achieve, that is to say, depending on the positioning of the deck 17 and the connecting member 25 attached thereto vis-à-vis the front foot 9, the width of the intermediate member 30, more particularly the width of the base 31, varies to ensure the connection between the connecting member and the front foot. In this way, it is possible to use an apron 17, a connecting member 25 and a front stand 9 standard for different body widths, that is to say for different types of vehicles, only the intermediate member 30 to be changed.
De la même manière que précédemment, l'ensemble des composants de la caisse sont fixés les uns aux autres par l'intermédiaire de points de soudure.In the same manner as before, all the components of the body are fixed to each other by means of welding points.
Comme il va de soi l'invention ne se limite pas à la forme de réalisation de cette caisse, décrite ci-dessus à titre d'exemple, mais elle embrasse au contraire toutes les variantes. It goes without saying that the invention is not limited to the embodiment of this box, described above as an example, but it embraces all variants.
