Description

Die vorliegende Erfindung betrifft einen Behälter für unter Druck stehende fluide Betriebsmittel von Fahrzeugen, insbesondere einem Druckgasbehälter, mit einem rohrförmigen Mantel aus Aluminium.The present invention relates to a container for pressurized fluid equipment of vehicles, in particular a compressed gas container, with a tubular jacket made of aluminum.

Um immer anspruchsvollere wirtschaftliche und umweltbezogene Anforderungen zu erfüllen, werden bei Fahrzeugen in zunehmende Maße alternative Treibstoffen eingesetzt. Unter den zur Verfügung stehenden alternativen Treibstoffen hat CNG (compressed natural gas) in den letzten Jahren sehr an Bedeutung gewonnen. Für die Speicherung von CNG in Fahrzeugen werden Speicherbehälter benötigt, welche gleichzeitig hohe Druckfestigkeit und geringes Gewicht haben sollten. Um diese Anforderungen zu erfüllen, werden CNG-Speicherbehälter derzeit aus Stahl oder Aluminiumlegierungen gefertigt. Aus Stahl hergestellte CNG-Speicherbehälter haben zwar eine hohe Druckfestigkeit, besitzen aber auch sehr hohes Gewicht, was der Leichtbauweise moderner Fahrzeuge zuwiderläuft. CNG-Speicherbehälter aus Aluminium werden bislang durch Umformen, z. B. Spinning, hergestellt, um Schweißnähte zu vermeiden und dadurch höhere Druckfestigkeit zu erzielen. Diese Fertigungsweise ist jedoch nur mit gut verformbaren Aluminiumlegierungen möglich, z. B. Legierungen der Gruppen 5xxx und 6xxx nach Standard EN 573 . Im Vergleich zu Stahlbehältern weisen solche Aluminium-CNG-Behälter dennoch wesentlich geringere Festigkeit auf, so daß zusätzliche Verstärkungsmaßnahmen getroffen werden müssen. Entweder muß die Wandstärke des Mantels erhöht werden, was das Gewicht des Behälters empfindlich anhebt, oder es muß eine zusätzliche Ummantelung mit einem Fasermaterial vorgesehen werden, welch letzteres die Herstellungskosten erhöht.To meet ever more demanding economic and environmental requirements, vehicles are increasingly using alternative fuels. Of the available alternative fuels, CNG (compressed natural gas) has become very important in recent years. For the storage of CNG in vehicles storage containers are required, which should have high pressure resistance and low weight at the same time. To meet these requirements, CNG storage tanks are currently made of steel or aluminum alloys. Although CNG storage tanks made of steel have a high compressive strength, but also have very high weight, which runs counter to the lightweight construction of modern vehicles. CNG storage tanks made of aluminum so far by forming, for. As spinning, made to avoid welds, thereby achieving higher pressure resistance. However, this manufacturing method is possible only with good deformable aluminum alloys, z. For example, alloys of groups 5xxx and 6xxx Standard EN 573 , However, compared to steel containers such aluminum CNG containers have much lower strength, so that additional reinforcing measures must be taken. Either the wall thickness of the shell must be increased, which raises the weight of the container sensitive, or it must be provided an additional sheath with a fiber material, which latter increases the manufacturing cost.

Die Erfindung setzt sich zum Ziel, einen Behälter für unter Druck stehende fluide Betriebsmittel von Fahrzeugen zu schaffen, der sowohl hohe Druckfestigkeit als auch geringes Gewicht hat und dabei einfach und kostengünstig herstellbar ist.The invention has for its object to provide a container for pressurized fluid equipment of vehicles, which has both high pressure resistance and low weight and is easy and inexpensive to produce.

Dieses Ziel wird mit einem Behälter der einleitend genannten Art erreicht, der sich gemäß der Erfindung dadurch auszeichnet, daß der Mantel aus einer Aluminiumlegierung der Gruppe 2xxx oder 7xxx gefertigt und an seinen beiden Stirnenden durch je einen eingeschraubten Stirndeckel verschlossen ist.This object is achieved with a container of the aforementioned type, which is characterized according to the invention in that the jacket made of an aluminum alloy of the group 2xxx or 7xxx and is closed at its two front ends by a respective screwed end cover.

In Abkehr von den bestehenden Lösungen werden durch die Erfindung erstmals hochfeste Aluminiumlegierungen der Gruppen 2xxx und 7xxx für den Einsatz in CNG-Speicherbehälter nutzbar gemacht, indem auf die bislang üblichen Umformschritte verzichtet wird. Legierungen dieser Gruppen zeichnen sich auch durch hohe Korrosionsfestigkeit und ein geringes Gewicht aus. Im Ergebnis wird ein Druckfluidbehälter mit hoher Druckfestigkeit, vergleichbar jener von Stahlbehältern, und geringem Gewicht, resultierend aus dem Einsatz von Aluminiumlegierungen, erzielt, ohne daß eine zusätzliche Ummantelung erforderlich wäre.In departure from the existing solutions, high-strength aluminum alloys of groups 2xxx and 7xxx are made usable for use in CNG storage tanks by the invention for the first time by dispensing with the hitherto customary forming steps. Alloys of these groups are also characterized by high corrosion resistance and low weight. As a result, a pressurized fluid container with high compressive strength, comparable to that of steel containers, and low weight resulting from the use of aluminum alloys, is achieved without the need for additional casing.

Die Stirndeckel könnten grundsätzlich aus einem anderen Material gefertigt werden als der Mantel. Besonders vorteilhaft ist es jedoch, wenn auch die Stirndeckel aus einer Aluminiumlegierung der Gruppe 2xxx oder 7xxx gefertigt sind.The end covers could basically be made of a different material than the coat. However, it is particularly advantageous if the end covers are made of an aluminum alloy of the group 2xxx or 7xxx.

In einer bevorzugten Ausführungsform der Erfindung werden Aluminiumlegierungen aus der Gruppe 7xxx ausgewählt. Diese Legierungen weisen eine besonders hohe Festigkeit und Korrosionsbeständigkeit auf.In a preferred embodiment of the invention, aluminum alloys from the group 7xxx are selected. These alloys have a particularly high strength and corrosion resistance.

Gemäß einem weiteren bevorzugten Merkmal der Erfindung wird der Mantel an seinen Endabschnitten nach innen eingeformt. Dadurch kann bei einer Druckbeaufschlagung des Behälterinneren eine gleichmäßige Spannungsverteilung in der Wandung des Mantels erreicht werden.According to a further preferred feature of the invention, the jacket is formed at its end portions inwardly. As a result, when pressure is applied to the interior of the container, a uniform distribution of stress in the wall of the jacket can be achieved.

Das Einformen der Endabschnitte kann auf besonders vorteilhafte Weise durch Aufstauchen vorgenommen werden, was eine kostengünstige Fertigung ermöglicht.The molding of the end portions can be made in a particularly advantageous manner by upsetting, which allows a cost-effective production.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung sind die Stirndeckel in Richtung zum Behälterinneren bombiert. Auf diese Weise dehnen sich die Stirndeckel bei Befüllung des Behälters mit Druckfluid in radialer Richtung nach außen hin aus, was die Dichtung zwischen ihrem Außenumfang und dem Mantel verstärkt.According to a further preferred embodiment of the invention, the end covers are cambered in the direction of the container interior. In this way, when the container is filled with pressurized fluid, the end caps expand radially outward, which reinforces the seal between its outer periphery and the shell.

Vorteilhaftweise werden die Stirndeckel durch Schmieden oder Thixocasting gefertigt. Durch diese Prozesse gefertigte Stirndeckel haben eine geringere Wandstärke im Vergleich zu mit anderen Verfahren, z. B. Druckgußverfahren, hergestellten Stirndeckeln.Advantageously, the end caps are made by forging or thixocasting. End caps made by these processes have a smaller wall thickness compared to other methods, eg. B. die casting, manufactured end covers.

Bevorzugt ist der Mantel von einer Hülle aus Fasermaterial umgeben, insbesondere bevorzugt aus einem Kohle- und/oder Glasfasergewebe oder -vlies, was eine Reduktion der Wandstärke des Mantels erlaubt. Daraus resultiert ein geringes Gewicht bei gleicher Druckfestigkeit; außerdem bieten Fasermaterialen einen hervorragenden Korrosionsschutz.Preferably, the sheath is surrounded by a sheath of fiber material, particularly preferably of a carbon and / or glass fiber fabric or fleece, which allows a reduction of the wall thickness of the sheath. This results in a low weight with the same pressure resistance; In addition, fiber materials offer excellent corrosion protection.

Äußerst vorteilhaft ist es, wenn zwischen dem Außenumfang des Stirndeckels und dem Innenumfang des Endabschnittes zumindest ein Dichtungsring vorgesehen ist, was eine noch bessere Dichtwirkung zwischen dem Außenumfang des Stirndeckels und dem Innenumfang seines Endabschnittes erlaubt.It is extremely advantageous if at least one sealing ring is provided between the outer circumference of the end cover and the inner circumference of the end section, resulting in an even better sealing effect between the outer circumference of the end cap Front cover and the inner circumference of its end portion allowed.

In jedem Fall ist es besonders günstig, wenn der Stirndeckel mit einem Flansch die Stirnseite des Endabschnittes unter Zwischenlegung einer Dichtung übergreift. Dadurch kann eine zusätzliche Abdichtung an der Stirnseite des Endabschnittes realisiert werden.In any case, it is particularly advantageous if the end cover engages over the front side of the end portion with the interposition of a seal with a flange. As a result, an additional seal on the end face of the end portion can be realized.

Der Mantel 2 hat in dem gezeigten Beispiel eine etwa zylindrische Form, d. h. etwa kreisförmigen Querschnitt. Es versteht sich jedoch, daß der Mantel 2 jede beliebige Querschnittsform haben kann, z. B. oval, polygonal, abgerundet-polygonal, z. B. abgerundet-rechteckig usw.The coat 2 has in the example shown an approximately cylindrical shape, ie approximately circular cross-section. It is understood, however, that the coat 2 can have any cross-sectional shape, z. B. oval, polygonal, rounded-polygonal, z. B. rounded-rectangular etc.

Die Stirndeckel 3, 4 sind mit Hilfe eines an ihrem Außenumfang vorgesehenen Gewindes 5 in Endabschnitte 6 des Mantels 2 eingeschraubt. Die Endabschnitte 6 können optional eine gegenüber dem restlichen Mantel 2 erhöhte Wandstärke haben. Am Innenumfang der Endabschnitte 6 und/oder dem Außenumfang der Stirndeckel 3, 4 können Absätze bzw. Nuten 7 angeordnet sein, um Dichtungsringe 8 aufzunehmen.The front cover 3 . 4 are by means of a provided on its outer circumference thread 5 in end sections 6 of the coat 2 screwed. The end sections 6 can optionally have one over the remaining jacket 2 have increased wall thickness. On the inner circumference of the end sections 6 and / or the outer periphery of the end covers 3 . 4 can paragraphs or grooves 7 be arranged to seal rings 8th take.

Die Stirndeckel 3, 4 können zusätzlich mit einem Flansch 10 ausgestattet sein, der zur Verstärkung die Stirnseite des Endabschnittes 6 übergreift. Auf der Anlageseite des Flansches 10 und/oder der Stirnseite des Endabschnittes 6 kann eine Ringnut 11 zur Aufnahme eines weiteren Dichtungsringes 12 ausgebildet sein.The front cover 3 . 4 can additionally with a flange 10 equipped to reinforce the end face of the end portion 6 overlaps. On the plant side of the flange 10 and / or the end face of the end portion 6 can be an annular groove 11 for receiving a further sealing ring 12 be educated.

Wie in 1 gezeigt, sind die Stirndeckel 3, 4 in Richtung zum Behälterinneren 13 hin bombiert, d. h. gewölbt. Dadurch dehnen sie sich bei erhöhtem Innendruck im Behälter 1 in radialer Richtung nach außen hin aus, was die Dichtung zwischen ihrem Außenumfang und dem Innenumfang der Endabschnitte 6 verstärkt.As in 1 shown are the end covers 3 . 4 towards the container interior 13 cambered, ie arched. As a result, they expand in the container at elevated internal pressure 1 in the radial direction outwardly, what the seal between its outer periphery and the inner periphery of the end portions 6 strengthened.

Der Mantel 2 und die Stirndeckel 3, 4 sind aus einer Aluminiumlegierung der Gruppe 2xxx (AlCu-Legierungen) oder 7xxx (AlZnMg-Legierungen) nach Standard EN 573 gefertigt. Besonders günstig sind Legierungen der Type 7xxx.
