Description
L'invention concerne un réservoir à carburant, en particulier pourThe invention relates to a fuel tank, in particular for
véhicules, constitué de deux pièces préformées raccordées par leurs bords et dont les faces vehicles, consisting of two preformed parts connected by their edges and whose faces
intérieures sont tournées l'une vers l'autre. interior faces toward each other.
On conna t dans la pratique des réservoirs à We know in practice tanks to
carburant pour véhicules constitués de deux pièces pré- fuel for vehicles consisting of two pre-
formées en forme de cuvette que l'on a soudées entre elles par leurs bords périphériques amenés au contact l'un de l'autre. Ces pièces préformées sont obtenues par emboutissage, ce qui suppose l'emploi de matériaux formed in the form of a bowl which has been welded together by their peripheral edges brought into contact with one another. These preformed parts are obtained by stamping, which supposes the use of materials

L'invention a pour but de donner à un réservoir à carburant fabriqué à partir de deux pièces préformées une conformation telle que la construction du réservoir puisse s'effectuer même avec un matériau non apte au The object of the invention is to give a fuel tank made from two preformed parts a conformation such that the construction of the tank can be carried out even with a material not suitable for
traitement par emboutissage.stamping treatment.
L'invention résoud ce problème en prévoyant que chacune des pièces préformées ait la forme d'une selle et The invention solves this problem by providing that each of the preformed parts has the shape of a saddle and
que les deux pièces préformées occupent par leurs mon- that the two preformed parts occupy by their
tants respectifs des positions tiercées et s'imbriquent l'une dans l'autre. Grâce à une telle structure, le choix du matériau est largement libre et il est même possible, en particulier, de construire le réservoir à carburant dans un alliage léger pour réaliser une réduction de respective ones of the third positions and overlap one another. Thanks to such a structure, the choice of material is largely free and it is even possible, in particular, to build the fuel tank in a light alloy to achieve a reduction in
poids.weight.
L'invention prévoit que l'une au moins des deux pièces préformées soit pourvue d'un filet marginal coudé périphérique. Pour l'autre pièce préformée, un filet marginal coudé n'est pas nécessaire. Au contraire, le bord peut se situer dans le plan de la paroi. Les bords des deux The invention provides that at least one of the two preformed parts is provided with a peripheral bent marginal thread. For the other preformed part, an angled marginal thread is not necessary. On the contrary, the edge may lie in the plane of the wall. The edges of the two
pièces préformées peuvent être réunis par soudage. preformed parts can be joined by welding.
L'invention prévoit également que l'une au moins des deux pièces préformées soit pourvue de moulures de The invention also provides that at least one of the two preformed parts is provided with moldings of
renforcement.enhancement.
Dans ce qui suit, l'invention est expliquée plus en détail à l'aide d'un exemple d'exécution illustré In the following, the invention is explained in more detail using an illustrated embodiment
par une figure.by a figure.
Le réservoir à carburant 1 représenté est cons- The fuel tank 1 shown is cons-
titué de deux pièces préformées 2 et 3. La pièce pré- formée 2 a une forme en U et comporte un fond allongé 4 sur les cotés étroits duquel sont disposés des montants et 6 arrondis à leur extrémité libre. Cette pièce pré- made up of two preformed parts 2 and 3. The preformed part 2 has a U shape and has an elongated bottom 4 on the narrow sides of which are uprights and 6 rounded at their free end. This piece pre-
formée 2 est dotée sur son bord d'un filet marginal pé- formed 2 has a marginal mesh on its edge
riphérique 7 recourbé vers l'extérieur. L'autre pière préformée 3 est un couvercle 8 profilé en V adapté par son secteur de liaison cintré 9 et les deux ailes 10, 11 faisant suite à celui-ci au contour marginal des montants , 6 du fond 4. Le fond 4 et le couvercle 8 sont super- posés avec leurs parois intérieures se faisant face et occupent par leurs montants 5, 6 et 10, 11 des positions tiercées. Fond et couvercle présentent à la jonction de leurs zones marginales périphériques un cordon de soudure continu étanche aux liquides. Pour donner de la rigidité au réservoir à carburant 1, les parois du fond 4 et celles des ailes 10 et 11 du couvercle 8 sont device 7 curved outwards. The other preformed post 3 is a V-shaped cover 8 adapted by its curved connecting sector 9 and the two wings 10, 11 following it at the marginal contour of the uprights, 6 of the bottom 4. The bottom 4 and the cover 8 are superimposed with their inner walls facing each other and occupy, by their uprights 5, 6 and 10, 11, third positions. Bottom and cover present at the junction of their peripheral marginal zones a liquid-tight continuous weld bead. To give rigidity to the fuel tank 1, the walls of the bottom 4 and those of the wings 10 and 11 of the cover 8 are
équipées de moulures de renforcement 12. fitted with reinforcement moldings 12.
