"Kraftstoffbehälter, insbesondere für Kraftfahrzeuge""Fuel tanks, especially for motor vehicles"
Die Erfindung betrifft einen Kraftstoffbehälter, insbesondere für Kraftfahrzeuge, aus zwei Formteilen, die längs ihrer Ränder bei einander zugewandten Innenseiten verbunden sind.The invention relates to a fuel tank, in particular for motor vehicles, made of two molded parts, which are connected along their edges with mutually facing inner sides.
Es sind Kraftstoffbehälter für Kraftfahrzeuge aus der Praxis bekannt, die aus zwei wannenförmigen Formteilen zusammengesetzt und über ihre umlaufenden ausgestellten und aneinander anliegenden Ränder miteinander verschweißt sind. Die Formteile sind dabei tiefgezogen, was die Verwendung von tiefziehfähigen Werkstoffen voraussetzt.There are fuel tanks for motor vehicles from the Known practice, which is composed of two tub-shaped molded parts and are welded to one another via their circumferential exposed and abutting edges. The molded parts are deep-drawn, which requires the use of deep-drawable materials.
Der Erfindung liegt die Aufgabe zugrunde, einen Kraftstoffbehälter aus zwei Formteilen so zu gestalten, daß dieser auch aus nicht tiefziehfähigem Werkstoff herstellbar ist.The invention is based on the object of a fuel tank to design from two molded parts so that it can also be made of non-deep-drawable material.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jedes der Formteile sattelförmig gestaltet ist und daß die beiden Formteile mit ihren Schenkeln gegeneinander versetzt und ineinandergreifend zusammengefügt sind. Durch eine derartige Gestaltung ergibt sich eine weitgehende Unabhängigkeit in der Werkstoffauswahl und es ist so insbesondere auch möglich zur Gewichtsreduzierung des Kraftstoffbehälters diesen aus Leichtmetall herzustellen.This object is achieved according to the invention in that each of the molded parts is designed in the shape of a saddle and that the two Molded parts are offset against each other with their legs and interlocking. By such a Design results in a high degree of independence in the choice of material, and it is so in particular possible to make the fuel tank from light metal to reduce the weight.
In Ausgestaltung der Erfindung kann mindestens eines der beiden Formteile mit einem umlaufenden, abgewinkelten Randsteg versehen sein.In an embodiment of the invention, at least one of the two molded parts can have a circumferential, angled edge web be provided.

Für das andere Formteil ist kein abgewinkelter Randsteg erforderlich. Der Rand kann hier vielmehr auch flächig mit der Wand auslaufen. Entlang ihren Rändern können die beiden Formteile durch Verschweißen verbunden sein.There is no angled edge web for the other molded part necessary. Rather, the edge can also run flat with the wall here. Along their edges can the both molded parts be connected by welding.
In weiterer Ausgestaltung der Erfindung kann mindestens eines der beiden Formteile mit Versteifungssicken versehen sein.In a further embodiment of the invention, at least one of the two molded parts can be provided with stiffening beads be.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in perspektivischer Ansicht schematisch dargestellt und im folgenden näher beschrieben.In the drawing is an embodiment of the invention shown schematically in a perspective view and described in more detail below.
Der dargestellte Kraftstoffbehälter i ist aus zwei Formteilen 2 und 3 aufgebaut. Von diesen weist das eine Formteil 2 U-Form auf und besteht aus einem langgestreckten Bodenteil k und an dessen Schmalseiten angeordneten Schenkeln 5 und 6, die an ihren freien Enden abgerundet sind. Dieses Formteil 2 ist an seinem Rand mit einem umlaufenden, nach außen abgebogenen Randsteg 7 versehen. Das andere Formteil 3 besteht aus einem im Querschnitt V-förmigen Deckteil 8, das mit seinem gekrümmten Verbindungsstück 9 und seinen beiden anschließenden Schenkeln 10, 11 dem Randverlauf der Schenkel 5» 6 des Bodenteils k angepaßt ist. Bodenteil k und Deckteil 8 sind miteinander zugewandten Innenseiten und gegeneinander versetzten Schenkeln 5, 6 und 10, 11 aufeinandergesetzt und an ihren umlaufenden aneinander anliegenden Randzonen in einer kontinuierlich umlaufenden Nahtschweißung flüssigkeitsdicht verbunden. Zur Versteifung des Kraftstoffbehälters 1 sind die Wandungen des Bodenteils k und die von den Schenkeln 10 und 11 des Deckteils 8 gebildeten Wandungen mit Versteifungssicken 12 versehenThe fuel tank i shown is made up of two molded parts 2 and 3. Of these, one molded part 2 has a U-shape and consists of an elongated bottom part k and legs 5 and 6 which are arranged on its narrow sides and which are rounded at their free ends. This molded part 2 is provided on its edge with a circumferential, outwardly bent edge web 7. The other molded part 3 consists of a cover part 8 which is V-shaped in cross section and which, with its curved connecting piece 9 and its two connecting legs 10, 11, is adapted to the edge profile of the legs 5 »6 of the bottom part k. Bottom part k and cover part 8 are mutually facing inner sides and mutually offset legs 5, 6 and 10, 11 placed on top of one another and connected in a liquid-tight manner at their circumferential adjacent edge zones in a continuously circumferential seam weld. To stiffen the fuel tank 1, the walls of the bottom part k and the walls formed by the legs 10 and 11 of the cover part 8 are provided with stiffening beads 12
