Description
CHARPENTE DE SUPPORT DE LA CARROSSERIE D'UN
VEHICLE
L'invention concerne une charpente de support de la carrosserie d'un véhicule constituée par une ossature qui délimite l'habitacle, les structures d'extrémité et le pavillon dans laquelle des éléments de profil constituent une cage rtticulaire de support de panneaux correpondants de la carrosserie.BODY SUPPORT FRAME OF A
VEHICLE
The invention relates to a support structure for the bodywork of a vehicle constituted by a framework which delimits the passenger compartment, the end structures and the roof in which the profile elements constitute a reticular cage for supporting the corresponding panels of the body.
La publication FR-A-2237799 décrit une charpente dans laquelle des montants latéraux, avant et arrière relient une ossature de toit au plancher du véhicule.The publication FR-A-2237799 describes a frame in which lateral, front and rear uprights connect a roof framework to the floor of the vehicle.
La publication FR-A-2537080 décrit une charpente constituée à partir d'éléments de profil de forme appropriée raccordés entre eux par soudage ou au moyen de pices de boulonnerie.The publication FR-A-2537080 describes a frame made up of profile elements of suitable shape connected together by welding or by means of bolts.
En raison de la forme et de la longueur des éléments, il est ncre de prévoir un grand nombre de dispositifs de raccordements et de noeuds d'assemblage.Due to the shape and length of the elements, it is necessary to provide a large number of connection devices and assembly nodes.
La confection de telles charpentes nécessite une main-d'oeuvre importante sur les postes d'assemblage. Des problèmes apparaissent également lors de la mise en oeuvre du traitement anti corrosion par la présence des noeuds d'assemblage difficiles à protéger efficacement.The making of such frames requires a significant workforce on the assembly stations. Problems also appear during the implementation of the anti-corrosion treatment by the presence of assembly nodes which are difficult to protect effectively.
Un but de l'invention est de fournir une charpente de support qui comparée aux charpentes connues, bénéficie d'une conception à base de modules préformés susceptibles d'entre acheminés sur le poste d'assemblage.An object of the invention is to provide a support structure which, compared to known structures, benefits from a design based on preformed modules capable of being routed to the assembly station.
Un autrc but de l'invention est une charpente support de la carrosserie rivalisée à partir d'un ensemble de cadres fermés rigidement reliés les uns aux autres, qui soit légère et susceptible d'être réalise à partir de profilés en métal léger tel que l'aluminium. Another object of the invention is a support structure for the bodywork rivaled from a set of closed frames rigidly connected to each other, which is light and capable of being produced from light metal profiles such as the 'aluminum.
L'invention a également pour objet une charpente de support dont les éléments déformables extérieurs à l'habitacle absorbent l'énergie résultant notamment des chocs accidentels.The invention also relates to a support frame whose deformable elements outside the passenger compartment absorb the energy resulting in particular from accidental shocks.
Selon l'invention chaque élément de profil fait partie d'un cadre fermé à segments d'assemblage rigidement reliés aux segments d'assemblage d'un cadre fermé adjacent.According to the invention each profile element is part of a closed frame with assembly segments rigidly connected to the assembly segments of an adjacent closed frame.
La charpente ainsi réalisée utilise avantageusement de profilés de métal allégés pour constituer des cadres destinés à port les principaux panneaux de la carrosserie tels que le pavillon, le pare-brise, la porte du véhicule.The frame thus produced advantageously uses lightened metal profiles to form frames intended to carry the main body panels such as the roof, the windshield, the vehicle door.
D'autres caractéristiques et avantages de la charpente apparaîtront à la lecture de la description d'une forme de réalisation de cellesi en référence au dessin annexé dans lequel: - la figure 1 est une représentation schématique de la charpente de
support d'une carrosserie de véhicule automobile, - la figure 2 est une représentation perspective d'une partie de la
charpente assemblée, - la figure 3 est une représentation perspective du déil m de la

La figure 1 représente une charpente de support de la carrosserie constituée par une ossature 100 qui délimite un habitacle 1 et des structures d'extrémité avant 2 et arrière 3 ainsi qu'une structure de pavillon 4. FIG. 1 represents a support structure for the bodywork constituted by a framework 100 which delimits a passenger compartment 1 and front 2 and rear 3 end structures as well as a roof structure 4.
L'ensemble de l'ossature possède l'aspect d'une cage réticulaire dont les éléments de profil remplissent notamment la fonction de montants et de longerons nécssaires à supporter les panneaux non représentés de la carrosserie tels qu'un pavillon, un pare-brise, un panneau latéral.The entire framework has the appearance of a reticular cage, the profile elements of which fulfill the function of uprights and side members necessary to support the panels, not shown, of the bodywork such as a roof, a windshield , a side panel.
Les divers éléments de profil representésâlafigure 1 et 2 font partie de cadres fermés réalisés par un procédé de pliage et de cintrage ainsi que cela est bien connu.The various profile elements shown in Figure 1 and 2 are part of closed frames made by a folding and bending process as is well known.
La figure l montre notamment une charpente qui possède:
A - Une structure d'habitacle 1 constituée par:
- deux cadres 1 1 support des portes latérales du véhicule,
- un cadre 12 support du pare brise 6,
- deux cadres 13, 14 support du pavillon 5,

La figure 1 représente schématiquement les liaisons entre des segments d'assemblage des cadres adjacents et notamment les liaisons entre les cadres 11-12;11-13;12-13 et13-14.FIG. 1 schematically represents the connections between assembly segments of the adjacent frames and in particular the connections between the frames 11-12; 11-13; 12-13 and 13-14.
De telles liaisons sont représentées à la figure 2 complétée par les figures 3 et 4 qui illustrent les zones d'assemblage des cadres 11, 13, 14, 15 (fig 3) et 11 - 12 - 13 (fig 4).Such connections are shown in Figure 2 supplemented by Figures 3 and 4 which illustrate the assembly areas of the frames 11, 13, 14, 15 (fig 3) and 11 - 12 - 13 (fig 4).
L'assemblage précité est opéré le long des divers segments des cades.The above assembly is carried out along the various segments of the frames.
A titre d'exemple le cadre il comporte un ensemble de segments lia, 11b, lic, îid, île dont les segments lia, 11b, lic sont respectivement assemblés aux segments l5a, 13b, 12c des cadres 15, 13, 12.By way of example, the frame includes a set of segments 11a, 11b, lic, îid, island whose segments 11a, 11b, lic are respectively assembled with the segments 15a, 13b, 12c of the frames 15, 13, 12.
La figure 2 montre en outre que: - les cadres assemblés tels que 13, 14 et 11, 15 sont contenus
sensiblement dans un même plan, - les cadres assemblés tels que 11, 13 - 11, 12 et 15, 14 sont contenus
dans des plans orthogonaux.Figure 2 further shows that: - the assembled frames such as 13, 14 and 11, 15 are contained
substantially in the same plane, - the assembled frames such as 11, 13 - 11, 12 and 15, 14 are contained
in orthogonal planes.
Selon une caractéristique de l'invention les divers segments d'assemblage tels que lia, llb, lic possdent au moins deux portées d'appui et de montage d'une cale d'espacement 40. Les figures 2, 3, 4 montrent un certain nombre de ces cales qui assurent la rigidité des jonctions établies entre les différents cadres.According to a characteristic of the invention, the various assembly segments such as 11a, 11b, lic have at least two bearing surfaces and for mounting a spacer 40. Figures 2, 3, 4 show a certain number of these shims which ensure the rigidity of the junctions established between the different frames.
La figure 3 illustre l'emploi de cales 40 au niveau des jonctions des cadres 13,14-14,15-15, liet 11,13. Figure 3 illustrates the use of shims 40 at the junctions of the frames 13,14-14,15-15, liet 11,13.
La figure 4 illustre l'emploi de cales 40 au niveau des jonctions des cadres 12,13-13,11 exil, 12.FIG. 4 illustrates the use of shims 40 at the junctions of the frames 12, 13, 13, 11 exile, 12.
Les cales 40 constituées par des portions de profil fermé creux à surs extdrieures d'assemblage permettent de la sorte la réalisation simplifiée de noeuds d'assemblage et la confection d'une charpente allégée. n est toutefois possible d'obtenir une meilleure précision de réalisation de la charpente en complétant l'assemblage par une suite d'entretoises disposées entre les cales successives telles que 40.The shims 40 constituted by hollow closed profile portions with external assembly seams allow in this way the simplified production of assembly nodes and the making of a lighter frame. However, it is possible to obtain better precision in the construction of the frame by completing the assembly with a series of spacers arranged between successive shims such as 40.
Les figures 10 à 18 montrent des variantes de réalisation de la section VI d'assemblage des cadres 11, 13 de la charpente représentée à la figure 2.FIGS. 10 to 18 show alternative embodiments of section VI for assembling the frames 11, 13 of the frame shown in FIG. 2.
Les figures 10 - 11 se rapportent aux assemblages collés.Figures 10 - 11 relate to the bonded assemblies.
Les figures 13 - 14 se rapportent aux assemblages soudés, le cas échéant à l'aide d'une plaque intermédiaire P (fig 14).Figures 13 - 14 relate to welded joints, if necessary using an intermediate plate P (fig 14).
