Die nächstliegende
Der erfindungsgemäße Drucktank des Patentanspruchs 1 weist eine besonders vorteilhafte Befestigung der Endstücke auf. Der nebengeordnete Patentanspruch 4 betrifft eine alternative Ausführungsmöglichkeit. Mit dem nebengeordneten Patentanspruch 7 erstreckt sich die Erfindung auch auf ein Verfahren zur Herstellung eines erfindungsgemäßen Drucktanks. Bevorzugte Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich analog für den Drucktank und für das Verfahren aus den abhängigen Patentansprüchen, der nachfolgenden Erfindungsbeschreibung und der Zeichnung.The pressure tank according to the invention of
Der erfindungsgemäße röhrenförmige bzw. rohrartige Drucktank (Rohrspeicher) zur Speicherung von Brennstoff in einem Kraftfahrzeug weist einen zylindrischen Hohlkörper auf, der an seinen beiden axialen Stirnseiten mit Endstücken verschlossen ist, wobei die Endstücke in den offenen stirnseitigen Enden, d. h. in den Öffnungen an den stirnseitigen Enden des zylindrischen Hohlkörpers angeordnet und jeweils durch wenigstens einen Sicherungsring (am zylindrischen Hohlkörper) fixiert sind, wie nachfolgend noch näher erläutert.The tubular or tubular pressure tank (pipe storage) according to the invention for storing fuel in a motor vehicle has a cylindrical hollow body which is closed at its two axial end faces with end pieces, the end pieces in the open front ends, i.e. H. are arranged in the openings at the front ends of the cylindrical hollow body and are each fixed by at least one locking ring (on the cylindrical hollow body), as explained in more detail below.
Mit „fixiert“ ist eine mechanische Befestigung der Endstücke am zylindrischen Hohlkörper gemeint, sodass diese zumindest in axialer Richtung (translatorisch), insbesondere aber auch in Umfangsrichtung (rotatorisch), festgehalten werden. Die Fixierung bzw. Befestigung erfolgt durch mittelbaren Formschluss zwischen den Endstücken und dem Hohlkörper bzw. dessen Hohlkörperwandung. Die erfindungsgemäße Fixierung der Endstücke ist sicher, ermöglicht eine ausreichende Kraftübertragung zwischen Endstück und zylindrischem Hohlkörper bzw. dessen Hohlkörperwandung und ist auch einfach herstellbar. Ergänzend können die Endstücke auch mit dem zylindrischen Hohlkörper verpresst (bzw. in den zylindrischen Hohlkörper eingepresst) und/oder verklebt sein, wobei der verwendete Klebstoff zugleich auch als Dichtung fungieren kann.“Fixed” means a mechanical fastening of the end pieces on the cylindrical hollow body, so that they are held at least in the axial direction (translational), but in particular also in the circumferential direction (rotational). The fixation or fastening takes place by means of an indirect form fit between the end pieces and the hollow body or its hollow body wall. The fixing of the end pieces according to the invention is secure, enables sufficient force transmission between the end piece and the cylindrical hollow body or its hollow body wall and is also easy to manufacture. In addition, the end pieces can also be pressed (or pressed into the cylindrical hollow body) and / or glued to the cylindrical hollow body, wherein the adhesive used can also function as a seal at the same time.
Sicherungsringe sind insbesondere ringartige, mit einer Ringöffnung versehene Befestigungselemente, welche in ähnlicher Ausführung zur Sicherung von Wellen (sogenannte Wellensicherungsringe bzw. -scheiben) verwendet werden. Die Sicherungsringe können an der Ringöffnung elastisch aufgeweitet (oder gegebenenfalls auch verengt) und dadurch sehr einfach montiert werden. Bevorzugt sind die Sicherungsringe einstückig aus Metall, insbesondere aus Blech (z. B. als Stanzteile), gefertigt.Retaining rings are in particular ring-like fastening elements provided with a ring opening, which are used in a similar design to secure shafts (so-called shaft retaining rings or washers). The securing rings can be elastically expanded (or possibly also narrowed) at the ring opening and can therefore be installed very easily. The retaining rings are preferably made in one piece from metal, in particular from sheet metal (e.g. as stamped parts).
Erfindungsgemäß ist vorgesehen, dass die Sicherungsringe außen am zylindrischen Hohlkörper angeordnet sind, insbesondere in Umfangsnuten, und (jeweils) mehrere (nach radial innen zeigende) Zungen aufweisen, welche die Hohlkörperwandung (Umfangswandung des zylindrischen Hohlköpers) durchdringen und formschlüssig in die Endstücke eingreifen, die dadurch fixiert sind. Die Hohlkörperwandung ist mit entsprechenden Löchern bzw. Durchlässen, insbesondere Einschnitten, für die Zungen ausgebildet. Bevorzugt sind die Zungen umfangssymmetrisch, d. h. in gleichen Winkelabständen, angeordnet.According to the invention it is provided that the retaining rings are arranged on the outside of the cylindrical hollow body, in particular in circumferential grooves, and (each) have several (radially inwardly pointing) tongues which penetrate the hollow body wall (circumferential wall of the cylindrical hollow body) and engage positively in the end pieces that are thereby fixed. The hollow body wall is designed with corresponding holes or passages, in particular incisions, for the tongues. The tongues are preferably circumferentially symmetrical, i. H. arranged at equal angular intervals.
Die Endstücke können jeweils mit zwei solchen, axial hintereinander bzw. axial nebeneinander angeordneten Sicherungsringen fixiert sein, wodurch eine sehr sichere Befestigung der Endstücke erzielt wird. Bevorzugt ist dabei vorgesehen, dass die beiden Sicherungsringe einen Drehversatz aufweisen bzw. dass die Zungen der beiden axial hintereinander angeordneten Sicherungsringe in Umfangsrichtung versetzt sind.The end pieces can each be fixed with two such locking rings arranged axially one behind the other or axially next to one another, whereby a very secure fastening of the end pieces is achieved. It is preferably provided that the two locking rings have a rotational offset or that the tongues of the two axially securing rings arranged one behind the other are offset in the circumferential direction.
Eine alternative Ausführungsmöglichkeit des erfindungsgemäßen röhrenförmigen Drucktanks sieht vor, dass die Endstücke in den offenen stirnseitigen Enden, d. h. in den Öffnungen an den stirnseitigen Enden des zylindrischen Hohlkörpers angeordnet und jeweils durch mehrere Sicherungsstifte (am zylindrischen Hohlkörper) fixiert sind, wie nachfolgend noch näher erläutert. An alternative embodiment of the tubular pressure tank according to the invention provides that the end pieces in the open front ends, d. H. are arranged in the openings at the front ends of the cylindrical hollow body and are each fixed by several locking pins (on the cylindrical hollow body), as explained in more detail below.
Sicherungsstifte sind insbesondere nagel- oder bolzenartige Befestigungselemente, mit deren Hilfe der zylindrische Hohlkörper und die Endstücke verbunden werden. Bevorzugt sind die Sicherungsstifte aus Metall gefertigt.Locking pins are in particular nail-like or bolt-like fastening elements with the aid of which the cylindrical hollow body and the end pieces are connected. The locking pins are preferably made of metal.
Die Sicherungsstifte könnten radial angeordnet sein, insbesondere derart, dass diese mit radialem Verlauf den zylindrischen Hohlkörper bzw. die Hohlkörperwandung und die Endstücke verbinden. Bevorzugt sind pro Endstück drei, vier oder mehr Sicherungsstifte vorgesehen, die umfangssymmetrisch, d. h. gleichmäßig über den Umfang verteilt bzw. in gleichen Winkelabständen, angeordnet sind.The locking pins could be arranged radially, in particular in such a way that they connect the cylindrical hollow body or the hollow body wall and the end pieces with a radial course. Preferably, three, four or more locking pins are provided per end piece, which are circumferentially symmetrical, i. H. are evenly distributed over the circumference or arranged at equal angular intervals.
Erfindungsgemäß ist jedoch vorgesehen, dass die Sicherungsstifte sekantenartig angeordnet sind, insbesondere derart, dass diese mit sekantenartigem Verlauf den zylindrischen Hohlkörper bzw. die Hohlkörperwandung und die Endstücke verbinden. Bevorzugt sind pro Endstück zwei, zueinander parallel angeordnete Sicherungsstifte vorgesehen.According to the invention, however, it is provided that the securing pins are arranged like a secant, in particular in such a way that they connect the cylindrical hollow body or the wall of the hollow body and the end pieces with a secant-like course. Preferably two locking pins arranged parallel to one another are provided for each end piece.
