Description

Die Erfindung betrifft ein Außenverkleidungsteil für ein Unterseeboot mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to an outer lining part for a submarine with the features specified in the preamble of claim 1.

Außenverkleidungsteile der in Rede stehenden Art bilden bei Unterseebooten üblicherweise den Teil der Außenhaut, der außenseitig des Druckkörpers und hiervon beabstandet angeordnet ist. Des Weiteren werden solche aus Faserverbundmaterialien bestehenden Außenverkleidungsteile auch zur Bildung der Außenhülle des Turmaufbaus eingesetzt.Exterior trim parts of the type in question form in submarines usually the part of the outer skin, which is arranged on the outside of the pressure hull and spaced therefrom. Furthermore, such outer cladding made of fiber composite materials are also used to form the outer shell of the tower structure.

Die vergleichsweise großen Abmessungen und das verhältnismäßig große Gewicht der Außenverkleidungsteile machen es erforderlich, diese Teile bei der Montage und Demontage z. B. beim Bau eines Unterseeboots oder bei Wartungsarbeiten nach der Indienststellung des Unterseeboots mit einem Kran zu transportieren und zu positionieren. Um die Außenverkleidungsteile an einem Kranhaken befestigen zu können, weisen sie metallische Aufnahmen für hierfür geeignete Befestigungselemente auf. Diese Aufnahmen sind in an den Außenverkleidungsteilen ausgebildeten Durchbrechungen verklebt.The comparatively large dimensions and the relatively large weight of the outer trim parts make it necessary, these parts during assembly and disassembly z. As in the construction of a submarine or maintenance work after the commissioning of the submarine with a crane to transport and position. In order to attach the outer lining parts to a crane hook, they have metallic receptacles for this purpose suitable fasteners. These recordings are glued in formed on the outer trim parts openings.

Nachteiligerweise hat sich gezeigt, dass in den Klebenähten zwischen dem Außenverkleidungsteil und den Aufnahmen für die Befestigungselemente häufig Risse auftreten. In diese Risse kann bei getauchtem Unterseeboot Seewasser eindringen. Bei solchen Außenverkleidungsteilen, die im Bereich des Turms und des Oberdecks eines Unterseeboots eingesetzt werden und bei aufgetauchtem Unterseeboot gegebenenfalls längere Zeit trocken liegen, kann dies in den Rissen zu einer vermehrten Salzansammlung und damit einhergehend zu beschleunigter Korrosion an den in den Durchbrechungen der Außenverkleidungsteile verklebten Aufnahmen führen. Die entstehenden Korrosionsprodukte, wie beispielsweise Rost, müssen aufwändig entfernt werden. Ungünstigstenfalls ist es erforderlich, korrodierte Aufnahmen durch Aufnahmen zu ersetzen, wobei das Entfernen der alten Aufnahmen zu einer Beschädigung des Außenverkleidungsteils führen kann. Dokument DE 102008052352 B3 wird als nächstliegender Stand der Technik angesehen und offenbart den Oberbegriff des Anspruchs 1. Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Außenverkleidungsteil für ein Unterseeboot zu schaffen, bei dem die oben beschriebenen Nachteile nicht oder zumindest deutlich vermindert auftreten.
Gelöst wird diese Aufgabe durch ein Außenverkleidungsteil mit den in Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen dieses Außenverkleidungsteils ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung sowie der Zeichnung. Hierbei können die in den Unteransprüchen und der Beschreibung angegebenen Merkmale gemäß der Erfindung jeweils für sich, aber auch in Kombination die erfindungsgemäße Lösung gemäß Anspruch 1 weiter ausgestalten.
Bei dem erfindungsgemäßen Außenverkleidungsteil für ein Unterseeboot kann es sich prinzipiell um jedes Außenverkleidungsteil handeln, das bei einem Unterseeboot einen Teil der Außenhaut oder einen Teil der Verkleidung des Turmaufbaus bildet. Dieses flächige Außenhautteil ist aus einem Faserverbundmaterial und bevorzugt aus einem kohlenstofffaserverstärkten oder glasfaserverstärkten Kunststoff ausgebildet. Wie bislang üblich, weist das Außenverkleidungsteil eine Aufnahme für ein Befestigungselement auf, mit dem das Außenverkleidungsteil beispielsweise über einen Hebegurt oder Stahlseil an einem Kranhaken befestigt werden kann. Gemäß der Erfindung ist diese Aufnahme allerdings lösbar an dem Außenverkleidungsteil befestigt. Unter einer lösbaren Befestigung im Sinne der Erfindung ist eine solche Befestigung zu verstehen, bei der die Aufnahme zerstörungsfrei von dem Außenverkleidungsteil entfernt werden kann. Diese Ausgestaltung des erfindungsgemäßen Außenverkleidungsteils ermöglicht es, das Außenverkleidungsteil aufgrund des bzw. der daran befestigten Aufnahmen und den an den Aufnahmen angebrachten Befestigungselementen während der Montage des Außenverkleidungsteils an einem Unterseeboot und während der Demontage dieses Teils von dem Unterseeboot mit einem Kran zu transportieren und zu positionieren und die Aufnahme nach einer solchen Montage bzw. Demontage von dem Außenverkleidungsteil zu entfernen, sodass die Aufnahme bzw. die Aufnahmen bei Einsatz des Unterseeboots nicht mehr der korrosionsfördernden Seewasserumgebung ausgesetzt sind. Des Weiteren müssen beim Bau eines Unterseeboots deutlich weniger Aufnahmen bereitgestellt werden, da die vorhandenen Aufnahmen für den Transport und die Positionierung mehrerer Außenverkleidungsteile wiederverwendet werden können.Disadvantageously, it has been found that cracks often occur in the adhesive seams between the outer covering part and the receptacles for the fastening elements. Seawater can enter these cracks when the submarine is submerged. In the case of such external trim components used in the area of the tower and upper deck of a submarine and, if necessary, in submerged submarines dry for a long time, this can lead to increased salt accumulation in the cracks and concomitantly accelerated corrosion on the glued in the openings of the outer lining parts recordings. The resulting corrosion products, such as rust, must be laboriously removed. Unfortunately, it is necessary to replace corroded recordings with recordings, the removal of the old recordings can lead to damage of the outer trim part. document DE 102008052352 B3 Against this background, the invention has the object to provide an outer lining part for a submarine, in which the disadvantages described above do not occur or at least significantly reduced.
This object is achieved by an outer lining part with the features specified in claim 1. Advantageous developments of this exterior trim part will become apparent from the dependent claims, the following description and the drawings. In this case, the features specified in the dependent claims and the description according to the invention in each case, but also in combination, the inventive solution according to claim 1 further develop.
The outer lining part according to the invention for a submarine can, in principle, be any outer lining part which, in the case of a submarine, forms part of the outer skin or a part of the lining of the tower superstructure. This flat outer skin part is formed from a fiber composite material and preferably from a carbon fiber reinforced or glass fiber reinforced plastic. As hitherto usual, the outer lining part has a receptacle for a fastening element, with which the outer lining part, for example via a sling or steel cable to a crane hook can be attached. According to the invention, however, this receptacle is releasably attached to the outer trim part. Under a releasable attachment in the context of the invention, such an attachment is to be understood, in which the recording can be removed without destruction of the outer lining part. This embodiment of the exterior trim part according to the invention makes it possible to transport and position the exterior trim part with a crane on the basis of the receptacle attached thereto and the mounting elements attached to the receptacle during assembly of the exterior trim part to a submarine and during dismantling of this part from the submarine and remove the receptacle from the exterior trim panel after such assembly or disassembly such that the receptacle or receptacles are no longer exposed to the corrosive seawater environment when the submarine is deployed. Furthermore, when building a submarine, significantly fewer shots must be provided because the existing shots can be reused for the transportation and positioning of multiple exterior trim panels.

Bei der Befestigung der Aufnahme an dem Außenhautteil ist die Aufnahme vorzugsweise durch eine an dem Außenverkleidungsteil ausgebildete Durchbrechung durchgeführt. Diese Durchbrechung erstreckt sich durch das Außenverkleidungsteil senkrecht zu dessen Flachseiten innerhalb der von dem Außenverkleidungsteil aufgespannten Fläche. Nach dem Entfernen der Aufnahmen von dem Außenverkleidungsteil können die Durchbrechungen gegebenenfalls mittels geeigneter Verschlüsse geschlossen werden. Andererseits kann es auch von Vorteil sein, diese Durchbrechungen nicht zu verschließen, also offen zu halten, da zwischen den Außenverkleidungsteilen und dem Druckkörper des Unterseeboots in der Regel ein von Seewasser durchfluteter Zwischenraum besteht, der beim Abtauchen des Unterseeboots zu bewässern und nach dem Auftauchen des Unterseeboots zu entwässern ist, wobei die Durchbrechungen zusätzliche De- und Entwässerungsöffnungen bilden.When mounting the receptacle on the outer skin part, the receptacle is preferably carried out by an opening formed on the outer lining part. This opening extends through the outer covering part perpendicular to its flat sides within the plane defined by the outer covering part surface. After removing the recordings of the outer lining part, the openings can optionally be closed by means of suitable closures. On the other hand, it may also be advantageous not to close these openings, so keep it open, as between the outer trim parts and the pressure hull of the submarine usually flooded by seawater gap exists to water when diving the submarine and after the emergence of the To submerse submarines is, taking the openings form additional drainage and drainage openings.

Wegen des vergleichsweise großen Gewichts der Außenverkleidungsteile ist die Aufnahme zweckmäßigerweise formschlüssig an dem Außenverkleidungsteil befestigt. Dementsprechend sind die Aufnahme und das Außenverkleidungsteil in dem Bereich, in dem die Aufnahme an dem Außenverkleidungsteil befestigt ist, so ausgestaltet, dass der Zusammenhalt von Aufnahme und Außenverkleidungsteil durch ein in einander oder umgreifen von Teilkonturen der Aufnahme und des Außenverkleidungsteils hergestellt wird.Because of the comparatively large weight of the outer lining parts, the receptacle is expediently fastened in a form-fitting manner to the outer lining part. Accordingly, the receptacle and the outer covering part in the region in which the receptacle is attached to the outer covering part are designed such that the cohesion of the receptacle and the outer covering part is produced by means of one another or encompassing partial contours of the receptacle and the outer covering part.

Gemäß einer Weiterbildung der Erfindung ist bei einer durch eine Durchbrechung hindurchgeführten Aufnahme bevorzugt vorgesehen, dass die Aufnahme einen Rand der Durchbrechung an zwei voneinander abgewandten Seiten des Außenverkleidungsteils übergreift. Bevorzugt können die beiden Enden der Aufnahme, die bei durch die Durchbrechung geführter Aufnahme an deren beiden Flachseiten herausragen, gegenüber dem in der Durchbrechung befindlichen Teil der Aufnahme einen so erweiterten Querschnitt aufweisen, dass dieser Querschnitt größer als derjenige der Durchbrechung ist, wobei diese Enden der Aufnahme jeweils an einem an die Durchbrechung angrenzenden Bereich des Außenverkleidungsteils zur Anlage kommen.According to one embodiment of the invention is preferably provided in a guided through an opening recording that the receptacle overlaps an edge of the opening on two opposite sides of the outer trim part. Preferably, the two ends of the receptacle, which protrude at guided through the aperture receiving on the two flat sides, compared to the located in the opening portion of the receptacle have a so enlarged cross-section that this cross-section is greater than that of the opening, said these ends of the Receiving each come to a adjacent to the opening region of the outer trim part to the plant.

Bevorzugt weist die Aufnahme ein erstes und ein zweites Bauteil auf, die unter Bildung eines Formschlusses mit dem Außenverkleidungsteil miteinander verschraubt sind. Hierbei ist vorzugsweise das erste Bauteil zur Befestigung des Befestigungselements ausgebildet, während das zweite Bauteil als ein Verbindungselement dient, das letztendlich den Formschluss zwischen dem Außenverkleidungsteil und der Aufnahme herstellt.Preferably, the receptacle on a first and a second component, which are screwed together to form a positive connection with the outer lining part. In this case, the first component is preferably designed for fastening the fastening element, while the second component serves as a connecting element, which ultimately produces the positive connection between the outer covering part and the receptacle.

Vorteilhaft weist das erste Bauteil einen zylindrischen Grundkörper auf. An einem Ende dieses Grundkörpers ist ein Außengewinde und an dem anderen Ende ein Kragen ausgebildet. Unter einem Kragen ist hierbei eine gegenüber dem zylindrischen Grundkörper flanschähnliche Querschnittserweiterung zu verstehen. Der Kragen dient dazu, bei durch die Durchbrechung des Außenverkleidungsteils durchgeführter Aufnahme an einer Flachseite des Außenverkleidungsteils formschlüssig anzuliegen und im Zusammenwirken mit einem Verbindungselement, das an dem anderen Ende des Druckkörpers ausgebildete Außengewinde angeschraubt wird, einen Formschluss zwischen der Aufnahme und dem Außenverkleidungsteil herzustellen.Advantageously, the first component has a cylindrical base body. At one end of this body is a male thread and at the other end a collar is formed. Under a collar here is compared to the cylindrical body flange-like cross-sectional expansion to understand. The collar serves to positively abut in a performed by the opening of the outer trim part receiving on a flat side of the outer trim part and in cooperation with a connecting element, which is screwed to the other end of the pressure body formed external thread to make a positive connection between the receptacle and the outer trim part.

Bei dem zweiten Bauteil kann es sich grundsätzlich um eine gewöhnliche Mutter handeln. Allerdings ist sicherzustellen, dass der Außenquerschnitt dieser Mutter größer als der Querschnitt der an dem Außenverkleidungsteil ausgebildeten Durchbrechung ist, sodass die auf dem ersten Bauteil aufgeschraubte Mutter den Außenrand der Durchbrechung übergreift. Ein solches Übergreifen des Außenrandes der an dem Außenverkleidungsteil ausgebildeten Durchbrechung durch das zweite Bauteil der Aufnahme kann dann gewährleistet werden, wenn, wie es in einer weiteren vorteilhaften Ausgestaltung vorgesehen ist, das zweite Bauteil eine mit einem Kragen versehene Mutter ist. Das heißt, an einer Stirnseite ist an der Mutter ein scheibenförmiger Bereich vorgesehen, dessen Querschnitt größer als der Querschnitt der übrigen Mutter ist.The second component can basically be an ordinary nut. However, it must be ensured that the outer cross section of this nut is larger than the cross section of the opening formed on the outer lining part, so that the nut screwed onto the first component engages over the outer edge of the opening. Such overlapping of the outer edge of the opening formed on the outer covering part through the second component of the receptacle can then be ensured if, as provided in a further advantageous embodiment, the second component is a nut provided with a collar. That is, on a front side of the nut, a disc-shaped portion is provided, whose cross section is larger than the cross section of the rest of the mother.

Um zu verhindern, dass sich das zweite Bauteil der Aufnahme von deren ersten Bauteil unbeabsichtigt löst, ist die Schraubverbindung von erstem und zweitem Bauteil zweckmäßigerweise mittels einer Splintsicherung gesichert. So ist an dem zylindrischen Grundkörper des ersten Bauteils in einem Endbereich, der bei aufgeschraubtem zweiten Bauteil aus diesem herausragt, ein Spindloch zur Aufnahme eines Splints ausgebildet, der die Mutter formschlüssig auf dem zylindrischen Grundkörper des ersten Bauteils festhält.In order to prevent the second component of the receptacle from unintentionally releasing from its first component, the screw connection of the first and second component is expediently secured by means of a cotter pin. Thus, on the cylindrical base body of the first component in an end region, which protrudes from the latter when the second component is screwed on, a spindle hole is formed for receiving a split pin, which holds the nut positively on the cylindrical body of the first component.

Besonders vorteilhaft ist in einer Durchbrechung des Außenverkleidungsteils eine aus Faserverbundmaterial ausgebildete Führungsbuchse für die Aufnahme angeordnet. Diese Führungsbuchse, die die Durchbrechung bildet, durch die die Aufnahme hindurch geführt ist, dient zur Verfestigung der an dem Außenverkleidungsteil ausgebildeten Durchbrechung. Die Führungsbuchse ist zweckmäßigerweise aus Faserverbundmaterial ausgebildet. Sie kann in der an dem Außenverkleidungsteil ausgebildeten Durchbrechung eingeklebt sein oder zusammen mit dem Außenverkleidungsteil ausgehärtet werden, wobei sie sich stoffschlüssig mit dem Außenverkleidungsteil verbindet. Bevorzugt wird die Führungsbuchse durch Aufwicklung eines in Kunststoff getränkten Streifens aus Faserverbundmaterial hergestellt.Particularly advantageously, a guide bush made of fiber composite material is arranged for receiving in an opening of the outer lining part. This guide bush, which forms the opening through which the receptacle is guided, serves to solidify the opening formed on the outer lining part. The guide bush is expediently formed from fiber composite material. It may be glued in the opening formed on the outer covering part opening or be cured together with the outer lining part, wherein it connects cohesively with the outer lining part. Preferably, the guide bush is made by winding a plastic impregnated strip of fiber composite material.

Bevorzugt ist das Außenverkleidungsteil mehrschichtig in Sandwichbauweise ausgebildet. Konstruktiv günstig überdeckt bei einer solchen Ausgestaltung des Außenverkleidungsteils jeweils eine äußere Laminatschicht des Außenverkleidungsteils die beiden Stirnseiten der Führungsbuchse. Hierdurch werden die beim Anheben und beim Transport des Außenverkleidungsteils auf die Aufnahme wirkenden Kräfte vorteilhaft von dem Führungsrohr und von den an das Führungsrohr stirnseitig angrenzende Laminatschichten aufgenommen und in die Bauteilstruktur des Außenverkleidungsteils weiter geleitet.Preferably, the outer lining part is multi-layered in sandwich construction. Constructively favorably covered in such an embodiment of the outer lining part in each case an outer laminate layer of the outer lining part, the two end faces of the guide bush. As a result, the forces acting on the receptacle during lifting and transport of the outer trim part are advantageously taken up by the guide tube and by the front side of the guide tube adjacent laminate layers and forwarded in the component structure of the outer trim part.

Wie bereits angemerkt worden ist, dient die Aufnahme zur Befestigung eines Befestigungselements, über das das Außenverkleidungsteil an einem Kranhaken befestigt werden kann. Um ein solches Befestigungselement an der Aufnahme anbringen zu können, ist die Aufnahme vorteilhaft zur Bildung einer Schraubverbindung mit einem Befestigungselement ausgebildet. Bevorzugt ist an der Aufnahme eine Gewindebohrung ausgebildet, in die ein handelsübliches Befestigungselement, beispielsweise ein Klappauge eingeschraubt werden kann. Nachfolgend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in einer schematischen Schnittansicht einen Teil eines Außenverkleidungsteils, mit einer daran lösbar befestigten Aufnahme für ein Befestigungselement.As has already been noted, the receptacle serves for fastening a fastening element, by way of which the outer covering part can be fastened to a crane hook. In order to be able to attach such a fastening element to the receptacle, the receptacle is advantageously designed to form a screw connection with a fastening element. Preferably, a threaded bore is on the receptacle formed, in which a commercially available fastener, such as a pop-up can be screwed. The invention is explained in more detail with reference to an embodiment shown in the drawing.

Das dargestellte Außenverkleidungsteil 2 ist mehrschichtig in Sandwichbauweise ausgebildet. Es weist einen inneren Kern 4 auf, der von zwei flächig übereinander angeordneten Schichten 6 aus einem druckfesten Kunststoffschaum besteht. An dem Kern 4 ist eine Durchbrechung 8 ausgebildet, die sich quer zu den Flachseiten der Schichten 6 durch diese hindurch erstreckt.The outer lining part 2 shown is designed in a multi-layer sandwich construction. It has an inner core 4, which consists of two superposed layers 6 of a pressure-resistant plastic foam. At the core 4, an opening 8 is formed which extends transversely to the flat sides of the layers 6 therethrough.

In die Durchbrechung 8 ist eine Führungsbuchse 10 eingesetzt und dort mit dem Kern 4 verklebt. Die Führungsbuchse 10 ist druckfest ausgebildet und wird von einem ausgewickelten Streifen aus einem in Kunststoff getränkten Faserverbundmaterial gebildet.In the opening 8, a guide bush 10 is inserted and bonded there to the core 4. The guide bushing 10 is formed pressure-resistant and is formed by an unwrapped strip of a plastic-impregnated fiber composite material.

An einer ersten Außenseite des Kerns 6 ist eine Schicht 12 und an der anderen Außenseite des Kerns 6 eine Schicht 14 auflaminiert. In Einbaulage an einem Unterseeboot bildet die Schicht 12 eine Außenseite des Außenverkleidungsteils 2 und die Schicht 14 dessen einem von dem beabstandet von dem Außenverkleidungsteil 2 angeordneten Druckkörper des Unterseeboots zugewandte Innenseite.On a first outer side of the core 6, a layer 12 and on the other outer side of the core 6, a layer 14 is laminated. In installation position on a submarine, the layer 12 forms an outer side of the outer lining part 2 and the layer 14 of its one of the spaced from the outer lining part 2 arranged pressure body of the submarine facing inside.

Die Schichten 12 und 14 überdecken jeweils die Führungsbuchse 10. In der Schicht 12 ist eine Durchbrechung 16 ausgebildet und in der Schicht 14 ist eine Durchbrechung 18 ausgebildet. Die Lage und der Querschnitt der Durchbrechungen 16 und 18 korrespondieren mit der Lage und mit dem Querschnitt einer an der Führungsbuchse 10 ausgebildeten Durchbrechung 20. Durch diese Durchbrechung 20 ist eine Aufnahme 22 für ein Befestigungselement 24, mit dem das Außenverkleidungsteil 2 z. B. an einem Kranhaken befestigt bar ist, hindurchgeführt.The layers 12 and 14 each cover the guide bush 10. An opening 16 is formed in the layer 12 and an opening 18 is formed in the layer 14. The position and the cross section of the apertures 16 and 18 correspond to the position and with the cross section of one formed on the guide bush 10 Opening 20. Through this opening 20 is a receptacle 22 for a fastener 24, with which the outer lining part 2 z. B. is attached to a crane hook bar, passed.

Die Aufnahme 22 ist im Wesentlichen zweiteilig ausgebildet. Sie weist ein erstes Bauteil mit einem zylindrischen Grundkörper 26 auf, bei dem an einem Ende ein Kragen 28 ausgebildet ist. Dieses erste Bauteil ist durch die an der Führungsbuchse 10 ausgebildete Durchbrechung 20 hindurchgeführt, wobei der Kragen 28 den Rand der Durchbrechung 20 und auch die gesamte Führungsbuchse 10 radial übergreift.The receptacle 22 is formed substantially in two parts. It has a first component with a cylindrical base body 26, in which a collar 28 is formed at one end. This first component is passed through the formed on the guide bush 10 opening 20, wherein the collar 28 radially overlaps the edge of the opening 20 and the entire guide bush 10.

An dem von dem Kragen 28 abgewandten Ende des Grundkörpers 26 des ersten Bauteils der Aufnahme 22, das an der von der Schicht 14 gebildeten Außenseite des Außenverkleidungsteils 2 herausragt, ist ein Außengewinde 30 ausgebildet. Auf diesem Außengewinde 30 ist ein zweites Bauteil der Aufnahme 22 verschraubt. Bei diesem zweiten Bauteil der Aufnahme 22 handelt es sich um eine Mutter 32, bei der an einem in Aufschraubrichtung vorderen Ende ein Kragen 34 ausgebildet ist.At the end remote from the collar 28 of the main body 26 of the first component of the receptacle 22, which protrudes on the outside of the outer lining part 2 formed by the layer 14, an external thread 30 is formed. On this external thread 30, a second component of the receptacle 22 is screwed. In this second component of the receptacle 22 is a nut 32, in which a collar 34 is formed at a front end in the screwing.

Der Kragen 34 liegt bei auf dem Grundkörper 26 des ersten Bauteils aufgeschraubter Mutter 32 an der Außenseite der Schicht 14 des Außenverkleidungsteils 2 den Rand der Durchbrechung 20 sowie die gesamte Führungsbuchse 10 radial übergreifend an, wodurch die Aufnahme 22 an dem Außenverkleidungsteil 2 formschlüssig festgelegt ist. Aufgrund der Schraubverbindung von erstem und zweitem Bauteil ist die Aufnahme 22 von dem Außenverkleidungsteil 2 lösbar.The collar 34 is located on the base body 26 of the first component screwed nut 32 on the outside of the layer 14 of the outer lining part 2, the edge of the opening 20 and the entire guide bushing 10 radially across, whereby the receptacle 22 is fixed to the outer lining part 2 positively. Due to the screw connection of the first and second component, the receptacle 22 is detachable from the outer covering part 2.

Um zu verhindern, dass sich die Mutter 32 unbeabsichtigt von dem ersten Bauteil der Aufnahme 22 löst, ist eine Splintsicherung vorgesehen. Hierzu ist an dem Grundkörper 26 des ersten Bauteils der Aufnahme 22 an einem außenseitig der auf dem Grundkörper 26 aufgeschraubten Mutter 32 angeordneten Bereich ein quer zur Längsausdehnung des Grundkörpers 26 ausgerichtete Spindloch 36 ausgebildet, durch das ein Splint 38 geführt ist.In order to prevent the nut 32 inadvertently becoming detached from the first component of the receptacle 22, a split lock is provided. For this purpose, on the base body 26 of the first component of the receptacle 22nd On an outside of the nut 32 which is screwed onto the base body 26, a spindle hole 36 aligned transversely to the longitudinal extent of the base body 26 is formed, through which a split pin 38 is guided.

An dem ersten Bauteil der Aufnahme 22 ist achsgleich zur Mittelachse A der Aufnahme 22 eine Längsbohrung 40 ausgebildet. Angrenzend an den Kragen 28 des ersten Bauteils der Aufnahme 22 ist die Längsbohrung 40 mit einem Innengewinde 42 versehen. Das Innengewinde 42 dient zur formschlüssigen Aufnahme einer Schraube, mit der das Befestigungselement 24 in der Aufnahme 22 festgelegt ist. Bei dem Befestigungselement 24 handelt es sich um ein Klappauge.On the first component of the receptacle 22, a longitudinal bore 40 is formed coaxially to the central axis A of the receptacle 22. Adjacent to the collar 28 of the first component of the receptacle 22, the longitudinal bore 40 is provided with an internal thread 42. The internal thread 42 serves for the positive reception of a screw, with which the fastening element 24 is fixed in the receptacle 22. The fastener 24 is a pop-up eye.
