Description

Vorrichtung zum Verriegeln einer Tankmuldenabdeckung und Verfahren zur Montage der Verriegelungsvorrichtung Device for locking a tank well cover and method for mounting the locking device
Die Erfindung betrifft eine Verriegelungsvorrichtung zum Verriegeln einer Tankmuldenabdeckung, gemäß Oberbegriff des Anspruchs 1, ein Verfahren zur Montage einer Verriegelungsvorrichtung, gemäß Oberbegriff des Anspruchs 12, sowie eine Anordnung einer Verriegelungsvorrichtung an einem Fahrzeug, gemäß Oberbegriff des Anspruchs 13.The invention relates to a locking device for locking a tank well cover, according to the preamble of claim 1, a method for mounting a locking device, according to the preamble of claim 12, and an arrangement of a locking device on a vehicle, according to the preamble of claim 13.
Verriegelungsvorrichtungen der hier angesprochenen Art sind bekannt (DE 196 12 098 AI) . Sie dienen zum Verriegeln einer beweglichen Tankmuldenabdeckung, beispielsweise Tankklappe, in einer Schließstellung, in der die Tankmuldenabdeckung eine Montageöffnung in einem Karosserieteil eines Fahrzeugs abdeckt. Die bekannte Verriegelungsvorrichtung weist ein Verriegelungselement zum Blockieren der Tankmuldenabdeckung, einen Stellantrieb zum Verlagern des Verriegelungselements sowie einen an einer Wandung der Montageöffnung befestigten Führungskörper für das Verriegelungselement auf. Der Stellantrieb und das Verriegelungselement sind hinter einer Seitenwand des Fahrzeugs angeordnet, wobei der Stellantrieb sich an einer von außen über die Montageöffnung her unzugänglichen Stelle befindet und an einer Radhauswand befestigt ist. Der Zugang zum Stellantrieb beziehungsweise dessen Montageort ist nur von anderer Stelle möglich. Die Montage der Verriegelungsvorrichtung ist entsprechend zeit- und somit kostenaufwendig.Locking devices of the type mentioned here are known (DE 196 12 098 AI). They serve to lock a movable fuel tank cover, for example a fuel filler flap, in a closed position in which the fuel tank cover covers an assembly opening in a body part of a vehicle. The known locking device has a locking element for blocking the tank well cover, an actuator for moving the locking element and a guide body for the locking element fastened to a wall of the mounting opening. The actuator and the locking element are arranged behind a side wall of the vehicle, the actuator being located at a location which is inaccessible from the outside via the assembly opening and being fastened to a wheel house wall. Access to the actuator or its installation location is only possible from another location. The assembly of the locking device is correspondingly time-consuming and therefore costly.
Es ist Aufgabe der Erfindung, eine Verriegelungsvorrichtung der eingangs genannten Art zu schaffen, deren Anbringung am Fahrzeug nur wenig Zeit erfordert und vorzugsweise einfach durchführbar ist. Ein weiteres Ziel der Erfindung besteht darin, ein Verfahren zur zeitsparenden Montage der Verriegelungsvorrichtung am Fahrzeug anzugeben.It is an object of the invention to provide a locking device of the type mentioned at the outset, which requires little time to attach to the vehicle and is preferably simple to carry out. Another object of the invention is in specifying a method for time-saving assembly of the locking device on the vehicle.
Zur Lösung der Aufgabe wird eine Verriegelungsvorrichtung mit den Merkmalen des Anspruchs 1 vorgeschlagen. Die Verriegelungsvorrichtung zeichnet sich dadurch aus, dass sie als vormontierte, modulare Baueinheit ausgebildet und im Randbereich einer in einem Karosserieteil vorgesehenen Montageöffnung befestigbar ist. Der Zusammenbau der Verriegelungsvorrichtung erfolgt also vor deren Montage am Fahrzeug, so dass deren Anbringung am Fahrzeug selbst nur wenig Zeit erfordert, da die Verriegelungsvorrichtung als ein Teil verbaut wird und die Zugänglichkeit der Montagestelle am Fahrzeug über die Montageöffnung gegeben ist. Vorteilhaft ist ferner die verbesserte Ergonomie des Montagevorgangs gegenüber dem bei bekannten Verriegelungsvorrichtungen.To achieve the object, a locking device with the features of claim 1 is proposed. The locking device is characterized in that it is designed as a preassembled, modular unit and can be fastened in the edge region of an assembly opening provided in a body part. The locking device is thus assembled before it is installed on the vehicle, so that it does not take much time to attach it to the vehicle itself, since the locking device is installed as one part and the mounting location on the vehicle is accessible via the mounting opening. Another advantage is the improved ergonomics of the assembly process compared to that in known locking devices.
In einfachster Ausführungsform kann die Verriegelungsvorrichtung so ausgebildet sein, dass das Verriegelungselement direkt mit einem an der Tankmuldenabdeckung angeordneten oder daran ausgebildeten Gegenelement zusammenwirkt, um die in Schließstellung angeordnete Tankmuldenabdeckung gegen Öffnen zu sperren.In the simplest embodiment, the locking device can be designed such that the locking element interacts directly with a counter element arranged on or formed on the tank recess cover in order to lock the tank recess cover arranged in the closed position against opening.
Es wird ein Ausführungsbeispiel bevorzugt, bei dem die Verriegelungsvorrichtung eine Eingreiföffnung für ein mit dem Verriegelungselement zusammenwirkendes Gegenelement an der Tankmuldenabdeckung aufweist. Das Gegenelement greift bei in Schließstellung angeordneter Tankmuldenabdeckung in die Eingreiföffnung ein und ist darin mittels des Verriegelungselement blockierbar. Die EingreifÖffnung gewährleistet eine exakte Ausrichtung des Gegenelements relativ gegenüber dem Verriegelungselement und verbessert damit die Funktionssicherheit der Verriegelungsvorrichtung.An exemplary embodiment is preferred in which the locking device has an engagement opening for a counter-element cooperating with the locking element on the tank well cover. The counter element engages in the engaging opening when the tank recess cover is arranged in the closed position and can be blocked therein by means of the locking element. The engaging opening ensures an exact alignment of the counter element relative to the locking element and thus improves the functional reliability of the locking device.
In bevorzugter Ausführungsform umfasst die Verriegelungsvorrichtung eine Tankmuldenabdeckung-Anhebeeinrichtung, die ei- nen Push-Push-Mechanismus aufweist, dessen Funktionsprinzip zum Beispiel in ähnlicher Form zum Ein- und Ausfahren von Kugelschreiberminen eingesetzt wird. Aufbau und Funktion eines derartigen Mechanismus sind allgemein bekannt, so dass im Folgenden nur auf diesen Funktionsweise, jedoch nicht auf seinen konstruktiven Aufbau näher eingegangen wird. Es wird davon ausgegangen, dass die Tankmuldenabdeckung als verschwenkbare Tankklappe ausgebildet ist und sich in Schließstellung befindet. Durch Druckbeaufschlagung der Tankklappe wird der Push-Push-Mechanismus entriegelt und unterstützt dabei das Verschwenken der Tankklappe in Richtung ihre Offenstellung um einen bestimmten Winkelbereich. Das heißt, die Tankklappe wird an ihrem beweglichen Ende zumindest soweit angehoben, dass sie von einem Bediener hintergriffen und einfach geöffnet werden kann. Beim Verschwenken der Tankklappe aus der Offenstellung in die Schließstellung wird die Tankklappe über ihre Schließstellung hinaus verschwenkt, was auch als "Überdrücken" bezeichnet wird, wodurch der Push- Push-Mechanismus verriegelt wird. Die Tankmuldenabdeckung- Anhebeeinrichtung ist besonders dann vorteilhaft, wenn die Tankklappe in ihrer Schließstellung bündig mit der Fahrzeugaußenseite abschließt und keine Hintergriffsmöglichkeit gegeben ist.In a preferred embodiment, the locking device comprises a tank trough cover lifting device which NEN push-push mechanism, the principle of which is used, for example, in a similar form for retracting and extending ballpoint refills. The structure and function of such a mechanism are generally known, so that in the following only this mode of operation, but not its construction, will be discussed in more detail. It is assumed that the tank well cover is designed as a pivotable tank flap and is in the closed position. By pressurizing the fuel filler flap, the push-push mechanism is unlocked and supports the pivoting of the fuel filler flap in the direction of its open position by a certain angular range. This means that the fuel filler flap is raised at least to the extent that it can be gripped by an operator and easily opened. When the fuel filler flap is pivoted from the open position into the closed position, the fuel filler flap is pivoted beyond its closed position, which is also referred to as "overpressing", as a result of which the push-push mechanism is locked. The fuel tank cover lifting device is particularly advantageous if the fuel filler flap is flush with the outside of the vehicle in its closed position and there is no possibility of engagement.
Besonders bevorzugt wird ein Ausführungsbeispiel der Verriegelungsvorrichtung, bei der der Stellantrieb und die Tankmuldenabdeckung-Anhebeeinrichtung jeweils für sich als modulare Baueinheit ausgebildet sind. Diese werden vor der Montage der Verriegelungsvorrichtung zu einer einzigen Baueinheit miteinander verbunden. Vorteilhaft hierbei ist, dass bei einer defekten Baueinheit nicht beide Baueinheiten ausgetauscht werden müssen. Die beiden Baueinheiten sind vorzugsweise lösbar miteinander verbunden, beispielsweise verschraubt, so' dass sie einfach voneinander trennbar sind.An exemplary embodiment of the locking device is particularly preferred, in which the actuator and the tank recess cover lifting device are each designed as a modular unit. These are connected to one another before assembly of the locking device into a single structural unit. The advantage here is that in the case of a defective structural unit, it is not necessary to replace both structural units. The two building blocks are preferably detachably connected to each other, for example screwed, so 'that they are easily separable from each other.
Weiterhin wird ein Ausführungsbeispiel der VerriegelungsVorrichtung bevorzugt, das sich durch mindestens eine, auf einen Halteflansch aufschiebbare Haltenut auszeichnet, wobei der Halteflansch sich in beziehungsweise an der Montageöffnung befindet. Aufgrund dieser Ausgestaltung ist eine exakte, reproduzierbare Anbringung der Verriegelungsvorrichtung am Karosserieteil sichergestellt. Der Halteflansch und die Haltenut sind vorzugsweise so aneinander angepasst, dass beim Aufschieben der Verriegelungsvorrichtung eine Klemmverbindung gebildet wird, die die Verriegelungsvorrichtung lagefest am Karosserieteil fixiert. Auf weitere Befestigungsmittel kann vorzugsweise verzichtet werden, das heißt, die vorstehend beschriebene Nut-Flansch-Verbindung ist die einzigste Befestigungsstelle zwischen Verriegelungsvorrichtung und Karosserieteil, bevor die Tankmulde in die Montageöffnung eingesetzt und darin befestigt wird.Furthermore, an embodiment of the locking device is preferred, which is characterized by at least one Retaining flange slide-on retaining groove, wherein the retaining flange is located in or at the mounting opening. This configuration ensures an exact, reproducible attachment of the locking device to the body part. The holding flange and the holding groove are preferably matched to one another in such a way that when the locking device is pushed on, a clamping connection is formed which fixes the locking device in a fixed position on the body part. Further fastening means can preferably be dispensed with, that is to say the groove-flange connection described above is the only fastening point between the locking device and the body part before the tank recess is inserted into the mounting opening and fastened therein.
Nach einer Weiterbildung der Erfindung ist die Haltenut an einem Gehäuse der Tankmuldenabdeckung-Anhebeeinrichtung vorgesehen. Das Gehäuse besteht vorzugsweise aus Kunststoff, so dass die Haltenut in einfacher Weise bei der Herstellung des Gehäuses angeformt werden kann.According to a development of the invention, the holding groove is provided on a housing of the tank recess cover lifting device. The housing is preferably made of plastic, so that the retaining groove can be formed in a simple manner during the manufacture of the housing.
Bei einem besonders vorteilhaften Ausführungsbeispiel der Verriegelungsvorrichtung weist die Tankmuldenabdeckung- Anhebeeinrichtung mindestens zwei, in einem Abstand voneinander angeordnete Haltestege auf, wobei jeder der Haltestege eine Haltenut aufweist.

Figur 1 zeigt einen Ausschnitt eines Karosserieteils 1 eines nicht dargestellten Kraftfahrzeugs. Das Karosserieteil 1 kann beispielsweise von einer Fahrzeugseitenwand gebildet sein und weist eine Montageöffnung 3 auf, die zur Aufnahme von einer in Figur 2 dargestellten Verriegelungsvorrichtung 5 und einer in Figur 3 dargestellten Tankmulde 7 dient.Figure 1 shows a section of a body part 1 of a motor vehicle, not shown. The body part 1 can be formed, for example, by a vehicle side wall and has an assembly opening 3, which serves to receive a locking device 5 shown in FIG. 2 and a tank recess 7 shown in FIG. 3.
An der beispielsweise aus Kunststoff bestehenden, topfförmi- gen Tankmulde 7 ist eine in den Figuren nicht dargestellte, um eine Achse zwischen einer Schließstellung und einer Offenstellung schwenkbare Tankklappe angeordnet, die zur Abdeckung der Montageöffnung 3 dient. In der Schließstellung durchgreift ein an der Tankklappe vorgesehenes Gegenelement eine Durchgangsöffnung 9 in der Tankmulde 7, worauf noch näher eingegangen wird. Die Lagerstelle für die Tankklappe ist von einer über eine Seitenwand der Tankmulde 7 hinausragenden Verdickung 11 gebildet. Am oberen Rand der Tankmulde 7 ist ein umlaufender Flansch 13 ausgebildet, mit dem die Tankmulde 7 im eingebauten Zustand an einem an der Montageöffnung 3 vorgesehenen, zur Außenfläche des Karosserieteils 1 nach innen versetzt angeordneten Flansch 15 anliegt. Die Tankmulde 7 weist an ihrem Boden eine Öffnung 17 auf, die im eingebauten Zustand der Tankmulde 7 von einem Kraftstofffüllstutzen durchgriffen wird, der in die Tankmulde 7 hineinragt .A tank flap (not shown in the figures), which can be pivoted about an axis between a closed position and an open position and serves to cover the assembly opening 3, is arranged on the cup-shaped tank recess 7, which is made of plastic, for example. In the closed position, a counter element provided on the tank flap passes through a through opening 9 in the tank recess 7, which will be discussed in more detail below. The bearing point for the tank flap is formed by a thickening 11 projecting beyond a side wall of the tank recess 7. At the upper edge of the tank recess 7, a circumferential flange 13 is formed, with which the tank recess 7, in the installed state, bears against a flange 15 provided at the assembly opening 3 and offset inwards from the outer surface of the body part 1. The tank recess 7 has an opening 17 on its bottom, which in the installed state of the tank recess 7 is penetrated by a fuel filler neck which projects into the tank recess 7.
Der Tankklappe ist eine nicht dargestellte Übertotpunkt- Federmechanik zugeordnet, die die Tankklappe in Schließ- beziehungsweise Offenstellung hält. Der Aufbau und die Funktion der Übertotpunkt-Federmechanik ist allgemein bekannt, so dass hier nicht näher darauf eingegangen wird.The tank flap is assigned an over-center spring mechanism, not shown, which holds the tank flap in the closed or open position. The structure and function of the over-center spring mechanism is generally known, so that it will not be discussed in more detail here.
Das in den Figuren 5A bis 5C dargestellte Ausführungsbeispiel der Verriegelungsvorrichtung 5 besteht aus zwei separierbaren Baueinheiten, nämlich einem Stellantrieb 19 zur Verlagerung eines Verriegelungselements 20 und einer Tankmuldenabdeckung- Anhebeeinrichtung 21, die mit Hilfe von Befestigungsmitteln 23 zu einer modularen Baueinheit miteinander verbunden sind.The exemplary embodiment of the locking device 5 shown in FIGS. 5A to 5C consists of two separable structural units, namely an actuator 19 for displacing a locking element 20 and a tank recess cover lifting device 21, which are connected to one another with the aid of fastening means 23 to form a modular structural unit.
Der Stellantrieb 19 umfasst ein vorzugsweise aus Kunststoff bestehendes Gehäuse 25, an dem eine Führung 27 für das stift- förmige Verriegelungselement 20 vorgesehen ist. Die Führung 27 ist von einem an das Gehäuse 25 angeformten Abschnitt 29 gebildet, der eine Führungsöffnung aufweist, in der das Verriegelungselement 20 geführt ist. Das Verriegelungselement 20 ist in Richtung eines Doppelpfeils 31 zwischen einer Freigabestellung und einer Sperrstellung hin und her bewegbar, was mittels eines geeigneten, im Gehäuse 25 untergebrachten Motors, beispielsweise Linearmotor realisiert wird. Alternativ kann das Verriegelungselement auch mittels einer Kolben- Zylindereinheit oder dergleichen verlagert werden. Der Stellantrieb 19 wird von einer Zentralverriegelungsanlage des Kraftfahrzeugs gesteuert, wobei beim Verschließen des Kraftfahrzeugs das Verriegelungselement 20 in Sperrstellung und bei offenem Kraftfahrzeug in Freigabestellung verlagert wird.The actuator 19 comprises a housing 25, preferably made of plastic, on which a guide 27 for the pin-shaped locking element 20 is provided. The guide 27 is formed by a section 29 molded onto the housing 25 and having a guide opening in which the locking element 20 is guided. The locking element 20 can be moved back and forth in the direction of a double arrow 31 between a release position and a blocking position, which is realized by means of a suitable motor, for example a linear motor, accommodated in the housing 25. Alternatively, the locking element can also be displaced by means of a piston-cylinder unit or the like. The actuator 19 is controlled by a central locking system of the motor vehicle, the locking element 20 being shifted into the locked position when the motor vehicle is closed and in the release position when the motor vehicle is open.
Die Tankmuldenabdeckung-Anhebeeinrichtung 21 umfasst ein vorzugsweise aus Kunststoff bestehendes Gehäuse 33, das mit ei- ner Schachtähnlichen EingreifÖffnung 35 versehen ist, in die das Tankklappen-Gegenelement bei in Schließstellung angeordneter Tankklappe eingreift. Im Gehäuse 33 ist ein mit dem Tankklappen-Gegenelement zusammenwirkender Push-Push- Mechanismus angeordnet, wie er oben beschrieben ist. Im Gehäuse 33 ist ferner eine quer zur Einfahrrichtung des Tankklappen-Gegenelements in die Eingriffsöffnung 35 verlaufende Durchgangsöffnung vorgesehen, die seitlich in die Eingreiföffnung 35 mündet. Das Verriegelungselement 20 greift mit seinem freien Ende in die Durchgangsöffnung ein. In Sperrstellung ragt das Verriegelungselement 20 soweit in die Eingreiföffnung 35 hinein, dass das Tankklappen-Gegenelement gegen ein Ausfahren aus der EingreifÖffnung 35 gesperrt wird, so dass die Tankklappe in der Schließstellung blockiert ist und nicht in Offenstellung verschwenkt werden kann.The tank well cover lifting device 21 comprises a housing 33, preferably made of plastic, which is provided with a A shaft-like engaging opening 35 is provided, into which the tank flap counter element engages when the flap is arranged in the closed position. In the housing 33, a push-push mechanism cooperating with the tank flap counter element is arranged, as described above. In the housing 33 there is also a through opening which extends transversely to the direction of entry of the counter element of the fuel filler flap into the engagement opening 35 and which opens laterally into the engagement opening 35. The free end of the locking element 20 engages in the through opening. In the locked position, the locking element 20 protrudes into the engaging opening 35 to such an extent that the tank flap counter-element is blocked from moving out of the engaging opening 35, so that the tank flap is blocked in the closed position and cannot be pivoted in the open position.
Wie aus Figur 5A ersichtlich, sind am Gehäuse 33 zwei in einem Abstand voneinander angeordnete Haltestege 37 und 39 ausgebildet, die im Wesentlichen parallel zueinander verlaufen und an deren Endbereich jeweils eine Haltenut 41 ausgebildet ist. Die Haltenuten 41 sind auf Halteflansche 43 am Karosserieteil 1 aufschiebbar. Wie aus Figur 1 ersichtlich, sind die Halteflansche 43 an einem randseitigen Ausschnitt 45 der Montage ffnung 3 ausgebildet. Die Haltestege 37, 39 sind mit jeweils einem Loch 47 versehen, die bei eingebauter Verriegelungsvorrichtung 5, das heißt, bei auf die Halteflansche 43 aufgeschobenen Haltenuten 41 mit am Karosserieteil 1 vorgesehenen Durchgangslöcher 49 fluchten. Die Tankmulde 7 weist ebenfalls Durchgangslδcher 51 auf, die bei in die Montageöffnung 3 eingebrachter Tankmulde 7 mit den Durchgangslöchern 49 und den Löchern 47 fluchten. Zur gegenüber dem Karosserieteil 1 lagefesten Fixierung der Verriegelungsvorrichtung 5 und der Tankmulde 7 werden -vorzugsweise selbstschneidende- Schrauben 53 verwendet, die die Durchgangslöcher 49, 51 durchgreifen und in die Löcher 47 im Gehäuse 33 eingeschraubt werden. Die Schrauben 53 sind in Figur 4B mit gestrichelter Linie angedeutet . Im Folgenden wird die Montage der Verriegelungsvorrichtung 5 und der Tankmulde 7 am Karosserieteil 1 anhand der Figuren 4A und 4B näher erläutert. Die als modulare Baueinheit ausgebildete Verriegelungsvorrichtung 5 wird von außen in die Montageöffnung 3 eingebracht und mit ihren Haltenuten 41 auf die Halteflansche 43 am Randbereich der Montageöffnung 3 aufgeschoben, wie in Figur 4A mit einem Pfeil 55 angedeutet, und zwar soweit, bis deren Löcher 47 mit den Durchgangslöchern 49 im Karosserieteil 1 fluchten. Die Verriegelungsvorrichtung 5 ist in Figur 4A in vollständig ein- beziehungsweise aufgeschobener Position dargestellt. Es ist ersichtlich, dass die Verriegelungsvorrichtung 5 -von der Sichtweise eines von außen auf die Montageöffnung 3 blickenden Betrachters gesehen- größtenteils vom Karosserieteil 1 abgedeckt ist und nur noch ein Teil der Tankmuldenabdeckung-Anhebeeinrichtung 21 zu erkennen ist. In einem zweiten Schritt wird nun die Tankmulde 7 mit gegebenenfalls bereits vormontierter Tankklappe von außen in die Montageöffnung 3 eingeschwenkt, wobei deren Flansch 15 in Anlage mit dem Flansch 13 an der Montageöffnung 13 gebracht wird. In Figur 4B ist die Tankmulde 7 in ordnungsgemäß eingesetzter Position abgebildet. Es ist ersichtlich, dass die Tankmulde 7 im Bereich ihrer Durchgangsöffnung 9, die sich in fluchtender Position mit der EingreifÖffnung 35 der Tankmuldenabdeckung-Anhebeeinrichtung 21 befindet, eine an den Freiraum zwischen den Haltestegen 37, 39 angepasste Ausformung aufweist, die in den Freiraum eingreift, wodurch die Tankmulde 7 in gewünschter Weise in der Montageöffnung 3 ausgerichtet und gegen ein Verdrehen gesichert ist. Die Tankmulde 7 ist so ausgebildet, dass sie den in der Montageöffnung 3 angeordneten Teil der Verriegelungsvorrichtung 5 im Wesentlichen vollständig abdeckt, so dass nur noch der mit der Durchgangsöffnung 9 in Überdeckungsposition angeordnete Teil der Verriegelungsvorrichtung 5 zu erkennen ist. Zum Abschluss der Montagearbeiten werden schließlich die Tankmulde 7 und die Verriegelungsvorrichtung 5 mittels der Schrauben 53 mit dem Karosserieteil 1 verschraubt. Es bleibt festzuhalten, dass der an der Tankmuldenabdeckung- Anhebeeinrichtung 21 befestigte Stellantrieb 19 keine eigene Befestigungsstelle mit dem Karosserieteil 1 aufweist, sondern ausschließlich durch die ihrerseits direkt mit dem Karosserieteil 1 verbundene Tankmuldenabdeckung-Anhebeeinrichtung 21 am Karosserieteil 1 gehalten ist.As can be seen from FIG. 5A, two holding webs 37 and 39, which are arranged at a distance from one another, are formed on the housing 33 and run essentially parallel to one another and a holding groove 41 is formed at the end region thereof. The holding grooves 41 can be pushed onto holding flanges 43 on the body part 1. As can be seen from FIG. 1, the holding flanges 43 are formed on an edge cutout 45 of the mounting opening 3. The holding webs 37, 39 are each provided with a hole 47 which, when the locking device 5 is installed, that is to say when the holding grooves 41 are pushed onto the holding flanges 43, are aligned with through holes 49 provided on the body part 1. The tank recess 7 also has through holes 51 which are aligned with the through holes 49 and the holes 47 when the tank recess 7 is inserted into the mounting opening 3. For the positionally fixed fixing of the locking device 5 and the tank recess 7 relative to the body part 1 — preferably self-tapping screws 53 are used, which pass through the through holes 49, 51 and are screwed into the holes 47 in the housing 33. The screws 53 are indicated in FIG. 4B with a broken line. The assembly of the locking device 5 and the tank recess 7 on the body part 1 is explained in more detail below with reference to FIGS. 4A and 4B. The locking device 5, which is designed as a modular unit, is introduced from the outside into the mounting opening 3 and pushed with its holding grooves 41 onto the holding flanges 43 at the edge region of the mounting opening 3, as indicated by an arrow 55 in FIG align the through holes 49 in the body part 1. The locking device 5 is shown in FIG. 4A in the fully pushed-in or pushed-on position. It can be seen that the locking device 5 - as seen by an observer looking from the outside at the assembly opening 3 - is largely covered by the body part 1 and only part of the tank recess cover lifting device 21 can be seen. In a second step, the tank recess 7, with a possibly already pre-assembled tank flap, is now pivoted from the outside into the assembly opening 3, the flange 15 of which is brought into contact with the flange 13 at the assembly opening 13. In Figure 4B, the tank recess 7 is shown in the properly inserted position. It can be seen that the tank recess 7 in the region of its passage opening 9, which is in the aligned position with the engagement opening 35 of the tank recess cover lifting device 21, has a shape which is adapted to the free space between the holding webs 37, 39 and which engages in the free space, whereby the tank recess 7 is aligned in the desired manner in the mounting opening 3 and secured against rotation. The tank recess 7 is designed such that it essentially completely covers the part of the locking device 5 arranged in the mounting opening 3, so that only the part of the locking device 5 arranged with the through opening 9 in the overlapping position can be seen. At the end of the assembly work, the tank recess 7 and the locking device 5 are finally screwed to the body part 1 by means of the screws 53. It should be noted that the actuator 19 fastened to the tank body cover lifting device 21 does not have its own fastening point with the body part 1, but is held on the body part 1 exclusively by the tank body cover lifting device 21 which is directly connected to the body part 1.
Der Anschluss des Stellantriebs 19 an die Zentralverriege- lungsanlage und an die Energieversorgung des Kraftfahrzeugs erfolgt -je nach Lage der Anschlüsse am Stellantrieb 19 und der Kabelführung- vor dem Anbringen der Verriegelungsvorrichtung 5 am Karosserieteil 1 oder danach, wobei die Anschlüsse und die Kabelführung vorzugsweise so angeordnet beziehungsweise gewählt sind, dass der Anschluss von außen über die Montageöffnung möglich ist.The connection of the actuator 19 to the central locking system and to the power supply of the motor vehicle takes place — depending on the position of the connections on the actuator 19 and the cable guide — before the locking device 5 is attached to the body part 1 or after, the connections and the cable guide preferably in this way are arranged or selected so that the connection from the outside is possible via the assembly opening.
In Figur 4C ist die Innenseite des Karosserieteils 1 mit in die Montageöffnung 3 eingebauter Verriegelungsvorrichtung 5 und Tankmulde 7 gezeigt. Es ist ersichtlich, dass die Verriegelungsvorrichtung 5 mit dem Gehäuse 25 des Stellantriebs 19 an der Innenseite des Karosserieteils 1 anliegt beziehungsweise daran abstützt, wodurch Klappergeräusche vermieden werden.FIG. 4C shows the inside of the body part 1 with the locking device 5 and the tank recess 7 installed in the assembly opening 3. It can be seen that the locking device 5 with the housing 25 of the actuator 19 rests against or supports the inside of the body part 1, as a result of which rattling noises are avoided.
Zusammenfassend bleibt festzuhalten, dass bei dem anhand der Figuren beschriebenen Ausführungsbeispiel alle erforderlichen Montagearbeiten zum Anbringen der Verriegelungsvorrichtung 5 und der Tankmulde 7 am Karosserieteil 1 von außen über die Montageöffnung 3 durchführbar sind, so dass eine gute Ergonomie des Montagevorgangs gewährleistet werden kann. Die Montage kann daher schnell und somit kostengünstig durchgeführt werden. Vorteilhaft ist ferner, dass das gesamte Arbeitsfeld vom Monteur einsehbar ist, so dass eine hohe Prozesssicherheit gegeben ist. In summary, it should be noted that in the exemplary embodiment described with reference to the figures, all the necessary assembly work for attaching the locking device 5 and the tank recess 7 to the body part 1 can be carried out from the outside via the assembly opening 3, so that good ergonomics of the assembly process can be ensured. The assembly can therefore be carried out quickly and therefore inexpensively. It is also advantageous that the entire working area is visible to the fitter, so that there is a high level of process reliability.
