Abstract
Description
La présente invention a pour objet un dispositif destiné à fixer un réservoir de carburant en matière thermoplastique à la caisse d'un véhicule automobile. The present invention relates to a device intended to fix a fuel tank of thermoplastic material to the body of a motor vehicle.
Le dispositif qui fait l'objet de l'invention est caractérisé en ce qu'il comprend, en combinaison, un réservoir muni de plusieurs pattes destinées à être fixées à la caisse au moyen de vis pour porter le réservoir dans les conditions normales de fonctionnement du véhicule ; une structure auxiliaire de soutien constituée par des bandes métalliques, destinée à entourer le réservoir à la façon d'un berceau et à être fixée à la caisse par des vis ou éléments analogues, ladite structure auxiliaire de soutien étant conformée et dimensionnée de manière à être exempte de tensions dans son état de montage et à jouer le rôle de support de secours pour le réservoir en cas d'incendie ou d'exposition à une chaleur intense. The device which is the subject of the invention is characterized in that it comprises, in combination, a tank provided with several lugs intended to be fixed to the body by means of screws to carry the tank under normal operating conditions of the vehicle ; an auxiliary support structure constituted by metal bands, intended to surround the tank in the manner of a cradle and to be fixed to the body by screws or the like, said auxiliary support structure being shaped and dimensioned so as to be free of tensions in its mounting state and play the role of emergency support for the tank in the event of fire or exposure to intense heat.
Le dispositif support qui fait l'objet de la présente invention est plus avantageux que les dispositifs proposés antérieurement, dans lesquels un réservoir en matière thermoplastique était relié à la caisse d'un véhicule. automobile par des bandes métalliques ayant à la fois pour fonction de tenir le réservoir en position pendant la marche normale et de soutenir le réservoir pour éviter qu'il ne s'effondre dans des conditions de détresse, c'est à-dire lorsque le réservoir est soumis à l'action du feu ou de la chaleur. The support device which is the subject of the present invention is more advantageous than the devices previously proposed, in which a tank made of thermoplastic material was connected to the body of a vehicle. automobile by metal bands having both the function of holding the tank in position during normal operation and of supporting the tank to prevent it from collapsing in distress conditions, that is to say when the tank is subjected to the action of fire or heat.
En effet, ce dispositif support connu n'assure pas une sécurité totale en cas de collision du véhicule et, dans les cas où il est prévu de monter en variante un réservoir en tâle à la place du réservoir en matière plastique, ce dispositif implique l'utilisation d'un ensemble réservoir métallique-structure support plus lourd et plus coûteux que celui selon l'invention. In fact, this known support device does not provide total security in the event of a vehicle collision and, in cases where it is planned to mount a variant of a sheet metal tank instead of the plastic tank, this device involves use of a heavier and more expensive metal tank-support structure assembly than that according to the invention.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de réalisation et en se réfé rant aux dessins annexés sur lesquels,
la figure 1 est une vue en perspective de dessous d'un réservoir de carburant relié à une caisse de véhicule automobile ;
la figure 2 est une vue éclatée des éléments de la figure 1 ;
la figure 3 est une coupe transversale à plus grande échelle, prise selon la ligne III-III de la figure 1 ; et
la figure 4 est une coupe transversale à plus grande échelle prise selon la ligne IV-IV de la figure 1 et
la figure 5 est une variante de la figure 4.Other characteristics and advantages of the invention will be better understood on reading the following description of an exemplary embodiment and with reference to the appended drawings in which,
Figure 1 is a perspective view from below of a fuel tank connected to a motor vehicle body;
Figure 2 is an exploded view of the elements of Figure 1;
Figure 3 is a cross section on a larger scale, taken along the line III-III of Figure 1; and
FIG. 4 is a cross section on a larger scale taken along line IV-IV of FIG. 1 and
FIG. 5 is a variant of FIG. 4.
En 1, on La indiqué un réservoir destiné à contenir le carburant d'un véhicule automobile et qui a été obtenu par soufflage d'une matière thermoplastique. In 1, there is indicated a tank intended to contain the fuel of a motor vehicle and which was obtained by blowing a thermoplastic material.
Le réservoir, de forme sensiblement parallélipipédique, présente deux pattes latérales indiquées par la référence 2 et une patte d'extrémité indiquée en 3. The reservoir, of substantially parallelepiped shape, has two lateral tabs indicated by the reference 2 and an end tab indicated at 3.
Les pattes 2 et 3 sont venues d'une seule pièce avec le réservoir au moment de la fabrication de ce dernier par soufflage et elles s'étendent entre les flancs de rainures indiquées respectivement en 6 et 7, qui sont ménagées dans la surface externe du réservoir. The legs 2 and 3 came in one piece with the reservoir at the time of the manufacture of the latter by blowing and they extend between the flanks of grooves indicated respectively in 6 and 7, which are formed in the external surface of the tank.
Les pattes 2 et 3 sont munies chacune d'un trou 4 servant à fixer le réservoir à la caisse du véhicule- à l'aide de vis 5. The legs 2 and 3 are each provided with a hole 4 used to fix the tank to the vehicle body using screws 5.
En 8, on a indiqué une structure auxiliaire de soutien constituée par une bande métallique 9 munie, à chacune de ses extrémités, d'un élément coudé 10 percé d'un trou 10a, et par une bande métallique 11 fixée à la bande 9 par l'une de ses extrémités, en 12, et munie à son autre extrémité d'un élément coudé 13 percé d'un trou 13a. At 8, there is indicated an auxiliary support structure constituted by a metal band 9 provided, at each of its ends, with a bent element 10 pierced with a hole 10a, and by a metal band 11 fixed to the band 9 by one of its ends, at 12, and provided at its other end with a bent element 13 pierced with a hole 13a.
La structure de soutien 8 est montée de manière à entourer le réservoir 1, la bande 9 se disposant dans la rainure 6 et la bande 11 dans la rainure 7. The support structure 8 is mounted so as to surround the reservoir 1, the strip 9 being arranged in the groove 6 and the strip 11 in the groove 7.
Ainsi qu'on l'a représenté sur les figures 3 et 4, on fixe la structure 8 à la caisse A du véhicule automobile au moyen des vis 5 et des écrous Sa, après. avoir disposé les éléments coudés 10 et 13 au-dessous des pattes 2 et 3 respectivement du réservoir. As shown in Figures 3 and 4, the structure 8 is fixed to the body A of the motor vehicle by means of screws 5 and nuts Sa, after. having the bent elements 10 and 13 below the legs 2 and 3 respectively of the tank.
Dans la variante représentée sur la figure 5, on a indiqué en 14 un élément tubulaire muni, à une extrémité, d'une collerette 15 que l'on introduit avant le montage du réservoir, à travers les trous de la bande métallique 7 et de la patte 3 du réservoir qui sont destinés à recevoir le -boulon 5 de fixation à la caisse A. L'autre extrémité de l'élément tubulaire est rabattue sur la patte 3 comme indiqué en 16, avec interposition d'une rondelle 17. In the variant shown in Figure 5, there is indicated at 14 a tubular member provided at one end with a flange 15 which is introduced before mounting the tank, through the holes of the metal strip 7 and the tab 3 of the tank which are intended to receive the bolt 5 for fixing to the body A. The other end of the tubular element is folded down on the tab 3 as indicated in 16, with the interposition of a washer 17.
De cette façon, on réalise avant le montage un assemblage stable entre les pattes du réservoir et les bandes métalliques de ia structure auxiliaire de soutien 8 dans la région des points d'ancrage sur la caisse, ce qui rend beaucoup plus facile l'opération consécutive de fixation à la caisse A au moyen des boulons 5.. Dans l'état de fonctionnement normal du véhicule automobile, la structure de soutien 8 est exempte de tensions, puisque le poids du réservoir est supporté intégralement par les pattes 2 et 3. In this way, a stable connection is made before assembly between the legs of the tank and the metal strips of the auxiliary support structure 8 in the region of the anchoring points on the body, which makes the subsequent operation much easier. for fixing to the body A by means of the bolts 5. In the normal operating state of the motor vehicle, the support structure 8 is free of tension, since the weight of the tank is fully supported by the legs 2 and 3.
La structure 8 intervient uniquement en cas de détresse, c'est-à-dire lorsque le réservoir 1 est attaqué par le feu ou par une chaleur intense, pour soutenir le réservoir, en évitant ainsi qu'il ne s'effondre et que le carburant ne s'en échappe en conséquence. The structure 8 intervenes only in the event of distress, that is to say when the tank 1 is attacked by fire or by intense heat, to support the tank, thus preventing it from collapsing and the fuel does not escape as a result.
Le dispositif de soutien du réservoir de carburant qui fait l'objet de la présente invention permet d'apporter les avantages suivants comparativement aux solutions proposées antérieurement pour fixer un réservoir de carburant en matière plastique à la caisse d'un véhicule automobile
al Possibilité d'utiliser pour un réservoir- de matière plastique les mêmes attaches de fixation à la caisse que pour un réservoir en tôle
b) pos-sibilité d'utiliser la structure auxiliaire de soutien prévue pour les réservoirs en matière plastique uniquement dans les pays où la législation exige les épreuves de résistance au feu, avec possibilité de s'adapter sans intervention ni modification de la caisse ou du châssis du véhicule lorsqu'un pays introduit une norme de ce genre au cours due la durée d'un modèle de véhicule donné ;
c) possibilité d'utiliser la structure auxiliaire de soutien même dans le cas de réservoirs en tôle, pour augmenter la rigidité du fond du réservoir
d) possibilité d'utiliser des bandes métalliques d'une épaisseur inférieure à celle des bandes métalliques proposées jusqu'à présent, en raison du fait que les bandes ont uniquement pour fonction de soutenir le réservoir en cas de détresse, la fonction de support étant normalement assurée par les pattes.The fuel tank support device which is the subject of the present invention makes it possible to bring the following advantages compared to the solutions proposed previously for fixing a plastic fuel tank to the body of a motor vehicle.
al Possibility of using for the plastic tank the same fasteners for fixing to the body as for a sheet metal tank
b) possibility of using the auxiliary support structure provided for plastic tanks only in countries where legislation requires fire resistance tests, with the possibility of adapting without intervention or modification of the body or vehicle chassis when a country introduces such a standard over the life of a given vehicle model;
c) possibility of using the auxiliary support structure even in the case of sheet metal tanks, to increase the rigidity of the bottom of the tank
d) possibility of using metal strips of a thickness less than that of the metal strips proposed so far, due to the fact that the strips have only the function of supporting the tank in the event of distress, the support function being normally provided by the legs.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of non-limiting example without departing from the scope of the invention.
