Abstract

The container e.g. compressed air reservoir (1) has two cup-shaped container halves produced by recasting steel plates (2, 4), where edges (12, 14) of the halves overlap in an overlapping region. The edges are curved in a pointed angle opposite to cladding walls (8, 10) adjacent to the edges in such a manner that the edges run parallel to each other in the overlapping region. An adhesive- or butt joint (18) is arranged between the edges. The edge (12) of the container halves is curved outwards in the overlapping region, and the other edge (14) runs like a gable in a cross section.

Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Behälter in einem Kraftfahrzeug, insbesondere einen Druckluftbehälter in einem Nutzfahrzeug, beinhaltend zwei durch Umformen von Stahlblechen hergestellte, becherförmige Behälterhälften, deren sich in einem Überlappungsbereich überlappende Ränder durch Kleben miteinander verbunden sind, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a container in a motor vehicle, in particular a compressed air tank in a commercial vehicle, comprising two cup-shaped container halves produced by forming steel sheets whose edges overlapping in an overlapping area are adhesively bonded together according to the preamble of claim 1.

Aus EP-A-48 890 ist ein Metallbehälter für eine unter Druck stehende Flüssigkeit bekannt, welcher aus zwei becherförmigen Behälterhälften besteht. Ein oberer einwärts geformter, parallel zur Behälterwand verlaufender Randbereich einer unteren Behälterhälfte ist dabei in eine obere Behälterhälfte eingeschoben. Die obere Behälterhälfte weist einen im spitzen Winkel nach außen abgebogenen Rand auf, der auf eine im spitzen Winkel schräg verlaufende Schulter, von welcher sich der eingeschobene obere Rand der unteren Behälterhälfte weg erstreckt, aufsitzt. Das Innenmaß des in die obere Behälterhälfte eingeschobenen Randes der unteren Behälterhälfte ist geringer ausgebildet als das Innenmaß der oberen Behälterhälfte. Im Bereich der sich überlappenden Ränder sind die beiden Behälterhälften durch Kleben miteinander verbunden.Out EP-A-48890 a metal container for a pressurized liquid is known, which consists of two cup-shaped container halves. An upper inwardly formed, parallel to the container wall extending edge region of a lower container half is inserted into an upper container half. The upper half of the container has an edge which is bent outwards at an acute angle and which rests on an inclined shoulder at an acute angle from which the inserted upper edge of the lower container half extends. The inner dimension of the inserted into the upper container half edge of the lower container half is formed smaller than the inner dimension of the upper container half. In the area of the overlapping edges, the two container halves are bonded together by gluing.

Druckluftbehälter in Nutzfahrzeugen werden zur Speicherung von Druckluft eingesetzt, die als Betätigungsmedium von Druckluftbremsen und anderen Einrichtungen von Nutzfahrzeugen wie beispielsweise einer Druckluftfederung, einer Türbetätigung oder von Kran- oder Hebeaufbauten dient. Darüber hinaus werden in Nutzfahrzeugen weitere Behälter wie beispielsweise Kraftstoffbehälter oder Hamstoffbehälter eingesetzt.Compressed air tanks in commercial vehicles are used for the storage of compressed air, which serves as the operating medium of compressed air brakes and other equipment of commercial vehicles such as a pneumatic suspension, a door operation or crane or lifting structures. In addition, further containers such as fuel tanks or urea containers are used in commercial vehicles.

Aus DE 199 57 855 A1 ist ein Druckluftbehälter bekannt, bei dem Ränder der Behälterhälften nicht thermisch gefügt sind, beispielsweise durch Klebung, um eine Beschädigung der Korrosionsschutzschicht z. B. durch die bei einem Schweißvorgang vorherrschenden, hohen Temperaturen zu vermeiden. Weiterhin überlappen sich die Ränder im Fügebereich in Form eines von der Mantelwandung nach radial außen ragenden Falzes. Die Fertigung des Falzes erfordert jedoch einen gewissen Aufwand. Außerdem besteht dabei eine erhöhte Verzugsgefahr, welche sich negativ auf die Maßhaltigkeit auswirken kann.Out DE 199 57 855 A1 a compressed air tank is known in the edges of the container halves are not thermally joined, for example by gluing, to damage the corrosion protection layer z. B. by prevailing at a welding process, high temperatures to avoid. Furthermore, the edges overlap in the joining region in the form of a fold projecting radially outward from the jacket wall. However, the production of the fold requires a certain effort. In addition, there is an increased risk of distortion, which can have a negative effect on the dimensional stability.

Der vorliegenden Erfindung liegt demgegenüber die Aufgabe zugrunde, einen Behälter der eingangs erwähnten Art derart weiter zu entwickeln, dass er bei hoher Festigkeit der Verbindung der Behälterhälften einfacher zu fertigen ist.The present invention is based on the object to further develop a container of the type mentioned in such a way that it is easier to manufacture with high strength of the connection of the container halves.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale von Anspruch 1 gelöst.According to the invention, this object is solved by the features of claim 1.

Die Erfindung schlägt vor, dass die Ränder der Behälterhälften in einem spitzen Winkel gegenüber an die Ränder angrenzenden Bereichen derart gebogen sind, dass sie zumindest im Überlappungsbereich eben parallel zueinander verlaufen und eine ihnen zwischengeordnete Klebe- oder Stoßfuge mit Klebstoff versehen ist.The invention proposes that the edges of the container halves are bent at an acute angle with respect to the edges adjacent areas such that they run parallel to each other at least in the overlapping area and an adhesive or butt joint between them is provided with adhesive.

Durch den Stoß der Behälterhälften entlang ihrer ebenen gebogenen Ränder entsteht einerseits eine große Klebefläche, wodurch eine feste Verbindung der Behälterhälften gewährleistet ist. Da ein Biegen der Ränder in lediglich spitzem Winkel geringere Spannungen in der Mantelwandung der Behälterhälften hervorruft als eine mehrlagige Falzung, wird der Materialverzug beim Umformen reduziert und die Maßhaltigkeit verbessert. Nicht zuletzt sorgt der rampenförmige Stoß der Behälterhälften im Bereich ihrer Ränder dafür, dass der dazwischen angeordnete Klebstoff beim Fügen der Behälterhälften nicht aus der Klebe- oder Stoßfuge verdrängt wird.By the collision of the container halves along their flat curved edges on the one hand creates a large adhesive surface, whereby a firm connection of the container halves is ensured. Since bending the edges at only an acute angle causes lower stresses in the shell wall of the container halves than a multi-layer fold, the material distortion during forming is reduced and the dimensional stability is improved. Not least, the ramp-shaped impact of the container halves in the region of their edges ensures that the adhesive arranged therebetween is not displaced from the adhesive or butt joint when joining the container halves.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Patentanspruch 1 angegebenen Erfindung möglich.The measures listed in the dependent claims advantageous refinements and improvements of the patent claim 1 invention are possible.

Besonders bevorzugt ist der Rand der einen Behälterhälfte im Überlappungsbereich nach außen eben gebogen und der Rand der anderen Behälterhälfte verläuft im Querschnitt gesehen giebelförmig. Ein solcher giebelförmiger Rand besteht in axialer Richtung gesehen aus einem rampenförmigen, nach radial außen weisenden ebenen Abschnitt, welchem sich nach Überschreiten eines Maximums ein ebenso rampenförmiger, aber nach radial innen gerichteter ebener Abschnitt anschließt, welcher zugleich das Randende bildet. Der giebelförmige Rand bildet im Wesentlichen eine Sicke aus, durch welche die Wandsteifigkeit des Behälters erhöht wird.Particularly preferably, the edge of the one container half in the overlap region is bent outward and the edge of the other container half extends gable-shaped in cross-section. As seen in the axial direction, such a gable-shaped edge consists of a ramp-shaped, radially outwardly pointing flat section, which, after exceeding a maximum, is followed by an equally ramp-shaped but radially inwardly directed planar section which at the same time forms the edge end. The gable-shaped edge essentially forms a bead, which increases the wall rigidity of the container.

Wenn in den an die Ränder angrenzenden Bereichen das Innenmaß der einen Behälterhälfte im wesentlichen gleich dem Innenmaß der anderen Behälterhälfte ist und zugleich das Innenmaß der anderen Behälterhälfte im Bereich eines freien Endes ihres Randes größer oder gleich den Innenmaßen der Behälterhälften in den an die Ränder angrenzenden Bereichen ist, dann wird auch bei großen Fertigungstoleranzen verhindert, dass sich die Ränder der Behälterhälften beim axialen Fügen übereinanderschieben und es nicht zu dem vorgesehenen Stoß entlang der Ränder kommt.If, in the areas adjacent to the edges, the internal dimension of one container half is substantially equal to the internal dimension of the other container half, and at the same time the internal dimension of the other container half in the region of a free end of its rim is greater than or equal to the internal dimensions of the container halves in the regions adjacent to the edges is, then it is prevented even at large manufacturing tolerances that the edges of the container halves slide over each other during axial joining and it does not come to the intended impact along the edges.

Der Winkel zwischen den Rändern im Überlappungsbereich und den an die Ränder angrenzenden Bereiche liegt bevorzugt in einem Bereich von 2 Grad bis 15 Grad, besonders bevorzugt beträgt er etwa 8 Grad.The angle between the edges in the overlap region and the regions adjacent to the edges is preferably in a range of 2 degrees to 15 degrees, more preferably about 8 degrees.

Gemäß einer weiteren Maßnahme kann der Rand wenigstens einer Behälterhälfte im Überlappungsbereich mit wenigstens einer entlang des Behälterumfangs umlaufenden Sicke oder Nut versehen sein, zur wenigstens teilweisen Aufnahme einer Dichtung, welche den Rand der anderen Behälterhälfte dichtend kontaktiert. Wenn zusätzlich die Dichtung von einem Innenraum des Behälters gesehen der mit Klebstoff versehenen Klebe- oder Stoßfuge vorgeordnet ist, dann wird die Dichtwirkung im Wesentlichen ausschließlich durch die Dichtung übernommen, während die Klebestelle hiervon entlastet wird und lediglich das Fügen der Behälterhälften übernimmt. Dadurch wird die Klebestelle in vorteilhafter Weise vor aggressiven Medien geschützt.According to a further measure, the edge of at least one container half in the overlapping region can be provided with at least one peripheral bead or groove along the container circumference, for at least partially receiving a seal which sealingly contacts the edge of the other container half. In addition, when viewed from an interior of the container, the seal is preceded by the adhesive or joint provided with adhesive, then the sealing effect is taken substantially exclusively by the seal, while the joint is relieved of this and only takes over the joining of the container halves. As a result, the splice is advantageously protected from aggressive media.

Nicht zuletzt sorgt die Dichtung, welche zugleich einen Abstandshalter für die zu fügenden Ränder der Behälterhälften darstellt, für die Einhaltung einer gewünschten Dicke der Klebefuge. Diese Funktion kann dann besonders vorteilhaft ausgeführt werden, wenn mehrere Dichtungen hintereinander angeordnet sind, so dass sich die Ränder der Behälterhälften an mehreren Stellen aneinander abstützen und während der Aushärtung des Klebers nicht gegeneinander verkippen können.Last but not least, the seal, which at the same time represents a spacer for the edges of the container halves to be joined, ensures that a desired thickness of the glue joint is maintained. This function can be carried out particularly advantageous if a plurality of seals are arranged one behind the other, so that the edges of the container halves abut each other at several points and can not tilt against each other during the curing of the adhesive.

Besonders bevorzugt wird der Behälter als Druckluftbehälter in einem Nutzfahrzeug zur Speicherung von Druckluft für eine Druckluftbremsanlage verwendet.Particularly preferably, the container is used as a compressed air tank in a commercial vehicle for storing compressed air for a compressed air brake system.

Weitere Vorteile ergeben sich aus den in den weiteren Unteransprüchen angegebenen Merkmalen.Further advantages result from the features specified in the further subclaims.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Der in Fig.1 nur ausschnittsweise gezeigte und insgesamt mit 1 bezeichnete Behälter dient gemäß einer bevorzugten Anwendung als Druckluftbehälter zur Speicherung von Druckluft für eine Druckluftbremsanlage eines Nutzfahrzeugs. Alternativ kann er zur Speicherung von Druckluft für jegliche Art von Druckluftverbraucher in Fahrzeugen dienen, beispielsweise für eine pneumatische Türbetätigung, für eine Druckluftfederung oder für weitere pneumatische Fahrzeugeinrichtungen oder Fahrzeugaufbauten.The in Fig.1 only partially shown and generally designated 1 container is used according to a preferred application as a compressed air tank for storing compressed air for a compressed air brake system of a commercial vehicle. Alternatively, it may be used to store compressed air for any type of compressed air consumer in vehicles, such as a pneumatic door operator, pneumatic suspension, or other pneumatic vehicle equipment or vehicle superstructures.

Wie Fig.1 veranschaulicht, ist der Druckluftbehälter 1 aus etwa zwei gleich großen Behälterhälften 2, 4 mit vorzugsweise kreisförmigem Querschnitt zusammengesetzt, welche durch Fügen ihres gemeinsamen Anschlussbereichs 6 miteinander dichtend verbunden sind. Die Behälterhälften 2, 4 bestehen aus bevorzugt an ihrer Innenfläche mit einer Korrosionsschutzbeschichtung versehenen Stahlblechen, welche durch einen Umformprozess, beispielsweise durch Tiefziehen in eine becherförmige Form gebracht wurden. Dies bedeutet, dass jede der Behälterhälften 2, 4 aus einem hier nicht sichtbaren Boden und einer hiervon rechtwinkelig weg ragenden Mantelwandung 8, 10 mit einer Öffnung besteht, welche jeweils durch einen Rand 12, 14 begrenzt wird. Gegebenenfalls können die Stahlbleche auch außen mit einer Korrosionsschutzbeschichtung versehen sein oder es können auch Stahlbleche ohne eine Korrosionsschutzbeschichtung verwendet werden.As Fig.1 illustrated, the compressed air tank 1 is composed of about two equal-sized container halves 2, 4 with preferably circular cross-section, which are connected by joining their common connection portion 6 together sealingly. The container halves 2, 4 consist of preferably provided on its inner surface with a corrosion protection coating steel sheets, which were brought by a forming process, for example by deep drawing in a cup-shaped mold. This means that each of the container halves 2, 4 consists of a bottom, not visible here, and a jacket wall 8, 10 protruding therefrom at right angles, with an opening which is delimited by an edge 12, 14. Optionally, the steel sheets may also be externally provided with a corrosion protection coating, or steel sheets without a corrosion protection coating may also be used.

Um die Korrosionsschutzbeschichtung durch hohe Temperaturen wie sie beim Schweißen entstehen würden, nicht zu zerstören, sind die freien Ränder 12, 14 der Behälterhälften 2, 4 durch Kleben miteinander verbunden. Dazu werden einander gegenüberliegende, ebene Flächen der Ränder 12, 14 im Bereich einer Klebe- oder Stoßfuge 18 mit einem Klebstoff versehen und durch axialen Druck der Behälterhälften 2, 4 gegeneinander gepresst. Als Klebstoff kommen jegliche für diese Anwendung geeigneten Klebstoffe, insbesondere hochfeste crashtaugliche Epoxidharze, Hot-melt-Kleber oder PUR-Kleber, jeweils als Ein- oder Zweikomponenten-Kleber in Frage. Die Dicke s des Klebers in der Klebe- oder Stoßfuge 18 wird fallweise je nach Anforderung angepasst. Anstatt die Behälterhälften 2, 4 vor dem Verkleben mit einer Korrosionsschutzschicht zu versehen, kann diese auch nach dem Verkleben aufgebracht werden.In order not to destroy the anticorrosive coating by high temperatures as they would arise during welding, the free edges 12, 14 of the container halves 2, 4 are connected by gluing together. For this purpose, opposite, planar surfaces of the edges 12, 14 are provided in the region of an adhesive or butt joint 18 with an adhesive and pressed against each other by axial pressure of the container halves 2, 4. Suitable adhesives are any adhesives suitable for this application, in particular high-strength crash-resistant epoxy resins, hot-melt adhesives or PUR adhesives, in each case as a one- or two-component adhesive. The thickness s of the adhesive in the adhesive or butt joint 18 is adjusted as needed depending on the requirement. Instead of providing the container halves 2, 4 with a corrosion protection layer prior to bonding, this can also be applied after bonding.

Der Anschlussbereich 6 der Behälterhälften 2, 4 zeichnet sich dadurch aus, dass sich deren Ränder 12, 14 dort in einem Überlappungsbereich 16 überlappen. Dabei sind die Ränder 12, 14 in einem spitzen Winkel gegenüber den an die Ränder 12, 14 angrenzenden Bereiche, welche durch die zylindrischen Mantelwände 8, 10 gebildet werden, derart gebogen, dass sie zumindest im Überlappungsbereich 16 eben parallel zueinander verlaufen und der Klebstoff in der Klebe- oder Stoßfuge 18 zwischen den zueinander weisenden Flächen der Ränder 12, 14 angeordnet ist. Bevorzugt liegt der Winkel α zwischen den Rändern 12, 14 im Überlappungsbereich 16 und den an die Ränder 12, 14 angrenzenden Bereichen 8, 10 in einem Bereich von 2 Grad bis 15 Grad, besonders bevorzugt beträgt er etwa 8 Grad.The connection region 6 of the container halves 2, 4 is characterized in that their edges 12, 14 overlap there in an overlapping region 16. In this case, the edges 12, 14 at an acute angle to the edges 12, 14 adjacent areas, which are formed by the cylindrical shell walls 8, 10, bent such that they extend parallel to each other at least in the overlapping region 16 and the adhesive in the adhesive or butt joint 18 is arranged between the mutually facing surfaces of the edges 12, 14. Preferably, the angle α between the edges 12, 14 in the overlap region 16 and the regions 8, 10 adjacent the edges 12, 14 is in a range of 2 degrees to 15 degrees, more preferably about 8 degrees.

Dies ist bevorzugt dadurch realisiert, dass der ebene Rand 12 der einen Behälterhälfte 2 im Überlappungsbereich 16 nach außen gebogen ist und der Rand 14 der anderen Behälterhälfte 4 im Querschnitt gesehen giebelförmig verläuft. Der giebelförmige Rand 14 der anderen Behälterhälfte 4 besteht in axialer Richtung gesehen aus einem rampenförmigen, nach radial außen weisenden ebenen Abschnitt 20, welchem sich nach Überschreiten eines Maximums 22 ein ebenso rampenförmiger, aber nach radial innen gerichteter ebener Abschnitt 24 anschließt, welcher in einem Randende 26 ausläuft. Mit anderen Worten bildet der Rand 14 eine nach radial außen prominente Sicke aus. Der Übergang von der Mantelwandung 10 zu dem nach außen weisenden Abschnitt 20 und der Übergang von diesem Abschnitt 20 zu dem nach innen weisenden Abschnitt 24 ist vorzugsweise mit einem Radius R verrundet.This is preferably realized in that the flat edge 12 of one container half 2 is bent outwards in the overlap region 16 and the edge 14 of the other container half 4 is gable-shaped as seen in cross-section. The gable-shaped edge 14 of the other container half 4 consists in the axial direction of a ramp-shaped, radially outwardly facing flat portion 20, which after exceeding a maximum 22, a similarly ramped, but radially inwardly directed planar portion 24 connects, which in one edge end 26 expires. In other words, the edge 14 forms a radially outwardly prominent bead. The transition from the jacket wall 10 to the outwardly facing portion 20 and the transition from this portion 20 to the inwardly facing portion 24 is preferably rounded with a radius R.

Der Innendurchmesser d1 der einen Behälterhälfte 2 ist etwa gleich groß wie der Innendurchmesser d2 der anderen Behälterhälfte 4. Zugleich ist der Innendurchmesser d3 der anderen Behälterhälfte 4 im Bereich des freien Randendes 26 größer oder gleich den Innendurchmessern d1, d2 der Behälterhälften 2, 4. Dadurch wird auch bei großen Fertigungstoleranzen verhindert, dass sich die Ränder 12, 14 der Behälterhälften 2, 4 beim axialen Fügen übereinanderschieben und es nicht zu dem vorgesehenen Stoß entlang der Ränder 12, 14 kommt.The inner diameter d 1 of one container half 2 is approximately the same size as the inner diameter d 2 of the other container half 4. At the same time, the inner diameter d 3 of the other container half 4 in the region of the free edge end 26 is greater than or equal to the inner diameters d 1 , d 2 of the container halves 2, 4. This prevents even at large manufacturing tolerances, that the edges 12, 14 of the container halves 2, 4 in axial joining over one another push and it does not come to the intended impact along the edges 12, 14.

Bei dem weiteren Ausführungsbeispiel der Erfindung nach Fig.2 sind die gegenüber dem vorhergehenden Beispiel gleich bleibenden und gleich wirkenden Teile durch die gleichen Bezugszeichen gekennzeichnet.In the further embodiment of the invention according to Fig.2 are the same with respect to the previous example and the same acting parts by the same reference numerals.

Im Unterschied zu diesem ist der Rand 14 beispielsweise der Mantelwandung 10 der anderen Behälterhälfte 4 mit wenigstens einer entlang des Behälterumfangs umlaufenden Sicke oder Nut 28 versehen, zur wenigstens teilweisen Aufnahme einer Dichtung 30, welche den Rand 12 der anderen Behälterhälfte 2 dichtend kontaktiert. Die Dichtung 30 besteht bevorzugt aus einem Radialdichtring. Dabei ist die Sicke oder Nut 28 im Überlappungsbereich 16 angeordnet und von einem Innenraum des Behälters 1 gesehen der Klebe- oder Stoßfuge 18 vorgeordnet. Die Nut oder Sicke 30 ist bevorzugt durch Umformen des Randes 14 gefertigt.In contrast to this, the edge 14, for example, the casing wall 10 of the other container half 4 is provided with at least one circumferential bead or groove 28 along the container circumference, for at least partially receiving a seal 30 which sealingly contacts the edge 12 of the other container half 2. The seal 30 preferably consists of a radial sealing ring. In this case, the bead or groove 28 is arranged in the overlapping region 16 and seen from an interior of the container 1 of the adhesive or butt joint 18 upstream. The groove or bead 30 is preferably made by forming the edge 14.

Besonders bevorzugt können noch weitere Nuten oder Sicken im Rand 14 beispielsweise der Mantelwandung 10 der anderen Behälterhälfte 4 ausgebildet sein, um mehrere Dichtungen 30, 36 hintereinander anzuordnen. Bei der Ausführung gemäß Fig.2 ist die weitere Nut oder Sicke 32 zwar auch im Überlappungsbereich 16 angeordnet, jedoch von einem Innenraum des Behälters 1 gesehen einer verrundeten Knickstelle 34 vorgeordnet, an welcher der Rand 12 der einen Behälterhälfte 2 gegenüber der restlichen Mantelwandung 8 abgebogen ist.Particularly preferred still further grooves or beads may be formed in the edge 14, for example, the jacket wall 10 of the other container half 4 to arrange a plurality of seals 30, 36 in a row. In the execution according to Fig.2 Although the further groove or bead 32 is also arranged in the overlap region 16, but seen from an interior of the container 1 a rounded kink 34 upstream, at which the edge 12 of a container half 2 is bent relative to the remaining casing 8.

Gemäß einer Alternative könnten die Nuten oder Sicken 28, 32 auch in dem Rand 12 der einen Behälterhälfte 2 ausgebildet sein, bzw. bei Vorhandensein mehrerer Nuten oder Sicken 28, 32 abwechselnd an dem Rand 12 der einen Behälterhälfte 2 und an dem Rand 14 der anderen Behälterhälfte 4 ausgebildet sein.According to an alternative, the grooves or beads 28, 32 could also be formed in the edge 12 of one container half 2, or in the presence of several grooves or beads 28, 32 alternately on the edge 12 of one container half 2 and on the edge 14 of the other Container half 4 may be formed.

Die Dichtungen 30, 36 welche zugleich Abstandhalter für die zu fügenden Ränder 12, 14 der Behälterhälften 2, 4 darstellen, gewährleisten die Einhaltung einer gewünschten Dicke s der Klebe- oder Stoßfuge 18. Diese Funktion kann dann besonders vorteilhaft ausgeführt werden, wenn mehrere Dichtungen 30, 36 hintereinander angeordnet sind, so dass sich die Ränder 12, 14 der Behälterhälften 2, 4 an mehreren Stellen aneinander abstützen und während der Aushärtung des Klebers nicht gegeneinander verkippen können. Grundsätzlich ist für die Erfüllung der genannten Funktion aber eine Dichtung 30 bzw. 36 ausreichend.The seals 30, 36 which at the same time constitute spacers for the edges 12, 14 of the container halves 2, 4 to be joined, ensure compliance with a desired thickness s of the adhesive or butt joint 18. This function can then be carried out particularly advantageously if a plurality of seals 30 , 36 are arranged one behind the other, so that the edges 12, 14 of the container halves 2, 4 are supported at several points together and can not tilt against each other during the curing of the adhesive. In principle, however, a seal 30 or 36 is sufficient for the fulfillment of said function.

Die Erfindung ist nicht auf Druckluftbehälter 1 beschränkt, sondern kann für jegliche Art von Behälter eingesetzt werden, beispielsweise für Kraftstoffbehälter oder Harnstoffbehälter in Nutzfahrzeugen, wobei dann auch die eingangs erwähnten Vorteile zum Tragen kommen.The invention is not limited to compressed air tank 1, but can be used for any type of container, such as fuel tanks or urea containers in commercial vehicles, in which case the benefits mentioned above come into play.
