Description

Die Erfindung betrifft einen Behälter für Kraftfahrzeuge, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a container for motor vehicles, according to the preamble of claim 1.

Aus der DE 44 07 075 C2 ist ein einwandiger Druckluftbehälter in Nutzfahrzeugen bekannt, dessen Wand auf ihrer Innenseite mit einer Korrosionsschutzschicht versehen ist. Die Wand des Druckluftbehälters ist aus wenigstens zwei, aus einem zweischichtigen Verbundwerkstoff vorgefertigten, nachfolgend zusammengesetzten und anschließend zusammengeschweißten, einzelnen Wandteilen hergestellt.From DE 44 07 075 C2 a single-walled compressed air tank in commercial vehicles is known, whose wall is provided on its inside with a corrosion protection layer. The wall of the compressed air tank is made of at least two, of a two-layer composite material prefabricated, subsequently assembled and subsequently welded together, produced individual wall parts.

Aus der US 4 131 980 A ist ein Tank aus Metall zur Aufnahme von flüssigem Kohlenwasserstoff sowie ein Verfahren zu dessen Herstellung bekannt. Hierbei werden zwei Behälterhälften mit hiervon abragenden Stegen gefertigt, die unter Einbringung eines mediumresistenten Klebers solcherart mehrmals umgefalzt werden, dass eine sechsfache Dicke dieser Falze gegenüber der übrigen Behälterwanddicke erzielt ist.From US 4,131,980 A is a metal tank for receiving liquid hydrocarbon and a method for its production. Here are two container halves made with protruding webs, which incorporates a medium-resistant Adhesive folded in such a way several times that a six-fold thickness of these folds achieved over the remaining container wall thickness.

Aus der EP 0 389 078 A2 ist ein Verfahren zur Herstellung von Druckgasflaschen bekannt, bei welchem wärmegefertigte Rohre durch ein Ablängen in Rohrabschnitte geteilt werden. Die einzelnen Rohrabschnitte werden anschließend mittels einer Warmumformung zu einem geschlossenen Behälter umgeformt und nach der Wärmebehandlung im Halsbereich der Druckgasflasche mechanisch bearbeitet.EP 0 389 078 A2 discloses a process for the production of compressed gas cylinders, in which heat-treated tubes are divided by cutting in pipe sections. The individual pipe sections are then by means of a hot forming to a closed container and after heat treatment in the neck area of the Gas cylinder machined.

Es ist Aufgabe der Erfindung, einen Druckluftbehälter in Kraftfahrzeugen in technisch und wirtschaftlich optimierter Weise darzustellen.It is an object of the invention to provide a compressed air tank in motor vehicles in technical and economically optimized way to represent.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.

Durch die erfindungsgemäße Darstellung eines Druckluftbehälters in Kraftfahrzeugen sind zunächst zwei in etwa gleichgroße Behälterhälften nach einem Umformverfahren, beispielsweise einem Press-, Tiefzieh-, Fließform-, Drückverfahren oder dergleichen hergestellt. Dabei sind öffnungsseitig beider Behälterhälften umfangsseitig umlaufende, etwa rechtwinklig hiervon abragende Stegränder gebildet, welche in einem nachfolgenden Arbeitsschritt durch nichtthermisches Fügen und unter zusätzlicher Verwendung eines Dichtmittels zu einer gemeinsam gebildeten, umfangsmäßig umlaufenden Falzverbindung umgeformt sind, durch welche die beiden Behälterhälften abdichtend miteinander verbunden sind. Dabei ist der Behälter ein Druckluftbehälter, dessen miteinander zu verbindende Behäfterhälften in etwa topfförmig ausgebildet sind und als Querschnittsform entweder einen Kreisquerschnitt oder eine von diesen abweichende Querschnittsform - beispielsweise eine bombierte Querschnittsform aufweisen.By the inventive illustration of a compressed air tank in motor vehicles initially two approximately equal container halves after a forming process, for example a compression, thermoforming, flow molding, spinning or the like. there are opening side of the container halves circumferentially encircling, approximately at right angles From this projecting web edges formed, which in a subsequent step by non-thermal joining and with the additional use of a sealant to a common formed, circumferentially circumferential fold joint are formed by which the two container halves are sealingly connected together. It is the Container a compressed air tank, the container halves to be connected together in about are cup-shaped and formed as a cross-sectional shape either a circular cross-section or one of these deviating cross-sectional shape - for example, a domed cross-sectional shape exhibit.

In letzterem Fall ist eine bessere Raumausnutzung erzielbar, d. h. bei gleichem Platzbedarf kann ein größerer Volumeninhalt im Druckluftbehälter realisiert sein.In the latter case, a better space utilization can be achieved, d.
