Description

Technisches Gebiettechnical field

Die Erfindung betrifft ein Lagerstelle für einen Heckklappen- oder Frontklappenbügel nach dem Oberbegriff des Anspruchs 1.The invention relates to a bearing point for a tailgate or front flap bracket according to the preamble of claim 1.

Stand der TechnikState of the art

Derartige Lagerstellen für einen Heckklappen- oder Frontklappenbügel sind bereits in vielfältiger Form und Ausgestaltung bekannt und gebräuchlich. So wird beispielsweise in der DE 10 2010 032 459 A1 eine Anordnung mit einer Klappe offenbart, die von einem Bügelscharnierarm gehalten ist, der an einem Lagerbock angelenkt ist, einer Feder, die ein Aufschwenken der Klappe zumindest unterstützt, und einer Rastierung, die mit einem Rastbereich des Bügelscharnierarms zusammenwirkt und die die Klappe in ihrer maximalen Offen-Position lösbar arretiert, dadurch gekennzeichnet, dass die Rastierung eine Aufnahme ist, in die der Rastbereich des Bügelscharnierarms beim Erreichen der maximalen Offen-Position der Klappe einschwenkt, wobei die Aufnahme außerhalb der Feder angeordnet ist und/oder den Rastbereich an mindestens drei Seiten aufnimmt.Such bearing points for a tailgate or front flap bracket are already known and used in a variety of forms and configurations. For example, in the DE 10 2010 032 459 A1 discloses an arrangement with a flap that is held by a bracket hinge arm that is articulated on a bearing block, a spring that at least supports pivoting the flap open, and a detent that interacts with a latching area of the bracket hinge arm and that the flap in its maximum Open position releasably locked, characterized in that the detent is a receptacle into which the detent area of the bracket hinge arm pivots when the maximum open position of the flap is reached, wherein the Recording is arranged outside of the spring and / or receives the latching area on at least three sides.

Weiter wird auf die EP 2 592 207 A2 verwiesen. Dort ist ein Scharnier offenbart, welches einen definierten Reibungswiderstand erzeugt, welcher die Handhabung des Scharniers verbessern soll.Next will be on the EP 2 592 207 A2 referred. A hinge is disclosed there, which generates a defined frictional resistance, which is intended to improve the handling of the hinge.

Außerdem wird auf die US 8,732,906 B1 hingewiesen, welches ein Scharnier aufzeigt bei dem ein erstes Scharnierteil und ein zweites Scharnierteil mit einer Scharnierbolzen durchgriffen werden, wobei der Scharnierbolzen verdrehfest mit dem ersten Scharnier verbunden ist und das zweite Scharnier frei drehend gegen das erste Scharnier angeordnet ist und dabei die gesamte Vorrichtung aus einem stromleitenden Werkstoff ist.In addition, on the US 8,732,906 B1 pointed out, which shows a hinge in which a first hinge part and a second hinge part are penetrated by a hinge bolt, the hinge bolt being connected to the first hinge in a rotationally fixed manner and the second hinge being arranged to rotate freely against the first hinge, and the entire device consisting of one electrically conductive material.

Zusätzlich wird auf die WO 95/16094 A verwiesen, welche eine Kontaktscheibe zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil auf dem Scharnierbolzen angeordnet ist.In addition, on the WO 95/16094 A referenced, which is arranged a contact disc between the first hinge part and the second hinge part on the hinge pin.

Die DE 199 60 736 C1 beschreibt ein Scharnier aus elektrisch leitendem Material, bestehend aus zwei Scharnierteilen, die mittels eines Scharnierstifts schwenkbar miteinander verbunden sind, wobei der Scharnierstift in einem Scharnierteil drehsicher festgelegt und im anderen Scharnierteil mit Laufsitz gelagert ist. Dabei sind die Teile, die aneinander anliegen und bei einer Schwenkbewegung relativ zueinander bewegt werden, in den aneinander anliegenden Bereichen durch eine elektrisch nicht leitende Beschichtung gegeneinander isoliert, wobei die Beschichtung mindestens an einer Stelle unterbrochen ist. Dabei ist die Unterbrechungsstelle von Beschichtungsmaterial umgeben und stellt eine elektrisch leitend Kontaktstelle zwischen den sich berührenden Teilen dar.The DE 199 60 736 C1 describes a hinge made of electrically conductive material, consisting of two hinge parts which are pivotally connected to one another by means of a hinge pin, the hinge pin being secured against rotation in one hinge part and mounted with a loose fit in the other hinge part. The parts that are in contact with one another and are moved relative to one another during a pivoting movement are insulated from one another in the areas that are in contact with one another by an electrically non-conductive coating, the coating being interrupted at least at one point. The point of interruption is surrounded by coating material and represents an electrically conductive contact point between the parts that are in contact.

Zuletzt wird auf die EP 3 498 956 A1 verwiesen, welch ein Scharnier für eine Kraftfahrzeugtür an einem Kraftfahrzeug mit einer ersten Scharnierhälfte und einer zweiten Scharnierhälfte, wobei die erste Scharnierhälfte drehfest mit einem Bolzen verbunden oder einstückig mit dem Bolzen ausgebildet ist und die zweite Scharnierhälfte eine Buchse aus Kunststoff aufweist, wobei die Buchse schwenkbar an dem Bolzen gelagert ist und zwischen Buchse und Bolzen ein leitendes Element angeordnet ist.Last will be on the EP 3 498 956 A1 referred, which a hinge for a motor vehicle door on a motor vehicle with a first hinge half and a second hinge half, the first hinge half being non-rotatably connected to a bolt or formed in one piece with the bolt and the second hinge half having a bushing made of plastic, the bushing being pivotably mounted on the bolt and a conductive element being arranged between the bushing and the bolt.

Um die Lackierbarkeit der einzelnen Teile durch den elektrophoretischen Abscheideprozess zu ermöglichen, wird die sogenannte kathodische Tauchlackierung (KTL) oder anodische Tauchlackierung (ATL) verwendet. Die kathodische Tauchlackierung, auch "Kataphorese" genannt, ist ein elektrochemisches Verfahren, bei dem das Werkstück in einem Tauchbad beschichtet wird.So-called cathodic dip painting (KTL) or anodic dip painting (ATL) is used to enable the individual parts to be painted using the electrophoretic deposition process. Cathodic dip painting, also known as "cataphoresis", is an electrochemical process in which the workpiece is coated in a dip bath.

Um die Lackierfähigkeit der Karosserie im KTL-Bad sicherzustellen, muss von einer Heckklappenanbindung zu einer Karosserieanbindung ein Stromfluss vorhanden sein. Die Leitfähigkeit wird im Stand der Technik z.B. durch Magnetbänder erreicht, die den Stromfluss zwischen den angesprochenen Teilen gewährleistet. Dies ist aufwändig und kostenintensiv, da in der Regel entsprechende Bohrungen auf den einzelnen Teilen zur verschraubten Befestigung der Magnetbänder zwischen den einzelnen Teilen notwendig sind.In order to ensure that the bodywork can be painted in the KTL bath, there must be a current flow from a tailgate connection to a bodywork connection. In the prior art, conductivity is achieved, for example, by means of magnetic tapes, which ensure the current flow between the parts in question. This is time-consuming and cost-intensive since, as a rule, corresponding bores are required on the individual parts for the screwed attachment of the magnetic tapes between the individual parts.

Aufgabe der Erfindungobject of the invention

Die Aufgabe der vorliegenden Erfindung ist es, die Nachteile aus dem Stand der Technik zu überwinden. Insbesondere soll eine Lagerstelle für einen Heckklappen- oder Frontklappenbügel bereitgestellt werden, bei der der Stromfluß zwischen den einzelnen Teil des Heckklappen- oder Frontklappenbügels kostengünstig herstellbar ist und gewährleistet werden kann.The object of the present invention is to overcome the disadvantages of the prior art. In particular, a bearing point for a tailgate or bonnet bracket is to be provided in which the current flow between the individual parts of the tailgate or bonnet bracket can be produced and guaranteed at low cost.

Lösung der Aufgabesolution of the task

Zur Lösung der Aufgabe führen die Merkmale nach dem Anspruch 1.The features according to claim 1 lead to the solution of the problem.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Advantageous configurations are described in the dependent claims.

Die erfindungsgemäße Lagerstelle für einen Heckklappen- oder Frontklappenbügel besteht in erster Linie aus drei Hauptteilen. Dabei handelt es sich um den Heckklappen- oder Frontklappenbügel, wobei der Heckklappen- oder Frontklappenbügel einends eine Karosserieanbindung und andernends eine Heckklappenanbindung aufweist. Dabei sind die Teile einzeln hergestellt und anschließend miteinander verbunden. Der Werkstoff alle Teile ist dabei ein Metall neuer Werkstoff, der Stromfluss-leitend ist.The bearing point according to the invention for a tailgate or front flap bracket consists primarily of three main parts. This is the tailgate or front lid bracket, the tailgate or front lid bracket having a body connection at one end and a tailgate connection at the other end. The parts are manufactured individually and then connected to each other. The material of all parts is a new metal material that conducts current flow.

Dies ist auch notwendig, da die Lackierbarkeit der einzelnen Teile durch den elektrophoretischen Abscheideprozess davon abhängt, dass eine Leitfähigkeit gewährleistet ist. Dazu wird die sogenannte kathodische Tauchlackierung (KTL) oder anodische Tauchlackierung (ATL) verwendet. Die kathodische Tauchlackierung, auch "Kataphorese" genannt, ist ein elektrochemisches Verfahren, bei dem das Werkstück in einem Tauchbad beschichtet wird.This is also necessary because the ability to paint the individual parts through the electrophoretic deposition process depends on ensuring conductivity. So-called cathodic dip painting (KTL) or anodic dip painting (ATL) is used for this. Cathodic dip painting, also known as "cataphoresis", is an electrochemical process in which the workpiece is coated in a dip bath.

Um die Lackierfähigkeit der Karosserie im KTL-Bad sicherzustellen, muss von der Heckklappenanbindung zu der Karosserieanbindung ein Stromfluss vorhanden sein.In order to ensure that the bodywork can be painted in the KTL bath, there must be a current flow from the tailgate connection to the bodywork connection.

Die einends an dem Heckklappen- oder Frontklappenbügel angeordnete Karosserieanbindung dient hierbei der Verbindung des Heckklappen- oder Frontklappenbügels mit der restlichen Karosserie. Die andernends des Heckklappen- oder Frontklappenbügels angeordnete Heckklappenanbindung dient dabei der Verbindung des Heckklappen- oder Frontklappenbügels mit einer Heckklappe. Bevorzugt kommt ein solcher Heckklappen- oder Frontklappenbügel bei Limousinen, bzw. Stufenheckfahrzeugen zum Einsatz. Dabei ist erfindungsgemäß zwischen der Karosserieanbindung und dem Heckklappen- oder Frontklappenbügel eine Kontaktscheibe angeordnet ist. Die Kontaktscheibe zeichnet sich in erster Linie dadurch aus, dass sie möglichst flach ausgebildet ist und mittig im Wesentlichen eine rotationsfreundliche bevorzugt runde Ausnehmung aufweist. Dabei weiß sie auch einen bevorzugt runden Außenumfang auf. Dies hat den Vorteil, dass sie zum einen auf eine zylindrisch ausgebildete Achse aufgezogen werden kann und zum anderen bei der Rotation der einzelnen Teile keine Angriffspunkte bietet und die Funktionsfähigkeit der Gesamtkonstruktion nicht beeinträchtigt.The body connection arranged at one end on the tailgate or front lid bracket serves to connect the tailgate or front lid bracket to the rest of the body. The tailgate connection arranged at the other end of the tailgate or front lid bracket serves to connect the tailgate or front lid bracket to a tailgate. Such a rear hatch or front hatch bar is preferably used in limousines or notchback vehicles. According to the invention, a contact disk is arranged between the body connection and the tailgate or front lid bracket. The contact disk is primarily characterized in that it is as flat as possible and essentially has a rotation-friendly, preferably round recess in the middle. It also has a preferably round outer circumference. This has the advantage that, on the one hand, it can be drawn onto a cylindrically designed axis and, on the other hand, it does not offer any points of attack when the individual parts rotate and does not impair the functionality of the overall construction.

Folglich kann es sich bei der Kontaktscheibe um einen Federring, eine Wellscheibe, ein Schlitzring, eine Zwischenscheibe, eine Tellerfeder oder ein anderes Kreiselement oder Teilkreiselement handelt.Thus, the contact washer may be a spring ring, corrugated washer, split ring, washer, Belleville washer, or other circular or pitch circular member.

Weiter ist ein Bolzen vorgesehen, der den Heckklappen- oder Frontklappenbügel zu der Karosserieanbindung haltend lagert. Dabei greift der Bolzen bevorzugt durch zwei Öffnungen der Karosserieanbindung und durch einen Durchlass des Heckklappen- oder Frontklappenbügels. Der Bolzen ist zumindest teilweise von einer Achse umfangen. Die Achse bildet dabei den Durchlass aus.A bolt is also provided, which mounts the tailgate or front lid bracket in a holding manner to the body connection. In this case, the bolt preferably engages through two openings in the body connection and through a passage in the tailgate or front lid bracket. The bolt is at least partially encompassed by an axle. The axis forms the passage.

Die Achse wiederum weist einends einen einstückig ausgebildeten Kragen auf. Der Kragen dient dabei als Anschlagsfläche der Achse zum Heckklappen- oder Frontklappenbügel. Auf diese Weise wird der Heckklappen- oder Frontklappenbügel im Bereich der Karosserieanbindung mit einfach definierter Reibung verschwenkbar gehaltert. Andernends weist die Achse eine zusätzliche Drehscheibe auf. Die Drehscheibe kann auch ähnlich dem Kragen einstückig mit der Achse ausgebildet sein. Die zweistückige Ausbildung hat aber den Vorteil, dass die Drehscheibe beim Verschwenken der Achse, ohne dass es zu Verschränkungen kommen kann, frei beweglich ist.The axle in turn has a one-piece collar at one end. The collar serves as a stop surface for the axle to the tailgate or front flap bracket. In this way, the rear hatch or front hatch bracket is held pivotably in the area of the body connection with simply defined friction. At the other end, the axis has an additional turntable. The turntable can also be formed in one piece with the axle, similar to the collar. However, the two-piece design has the advantage that the turntable can move freely when the axis is pivoted, without twisting occurring.

Die Achse ist in Arbeitslage von einer Karosseriehülse teilweise oder ganz umgriffen, wobei die Karosseriehülse ein Teil der Karosserieanbindung ist. In Arbeitslage bedeutet im Rahmen dieser Erfindung, wenn die einzelnen Hauptteile, wie Heckklappenbügel, Karosserieanbindung und Heckklappenanbindung, funktional zusammengebaut sind und zum Einsatz kommen könnten.In the working position, the axle is partially or completely encompassed by a body sleeve, the body sleeve being part of the body connection. In the context of this invention, in the working position means when the individual main parts, such as the tailgate bracket, body connection and tailgate connection, are functionally assembled and can be used.

Die Kontaktscheibe ist zwischen der Karosseriehülse und dem Kragen zumindest teilweise kontaktend angeordnet. Bei dieser Anordnung ist in besonderer Weise die Funktionalität des Stromflusses bei praktisch unbedeutender Beeinflussung des Reibungsverhaltens beim Verschwenken des Heckklappenbügel in die Offenstellung oder Verschlussstellung der Heckklappe gewährleistet.The contact disc is arranged at least partially in contact between the body sleeve and the collar. In this arrangement, the functionality of the current flow is ensured in a special way with a practically insignificant influence on the friction behavior when the tailgate bracket is pivoted into the open position or closed position of the tailgate.

In Figur 1 ist eine Lagerstelle dargestellt. Die Lagerstelle besteht in erster Linie aus einem Heckklappen- oder Frontklappenbügel 3, wobei der Heckklappen- oder Frontklappenbügel 3 einends eine Karosserieanbindung 1 und andernends eine Heckklappenanbindung 2 aufweist.In figure 1 a bearing point is shown. The bearing point consists primarily of a tailgate or front flap bracket 3, the tailgate or front flap bracket 3 having a body connection 1 at one end and a tailgate connection 2 at the other end.

Figur 1 ist die Schließstellung einer nicht gezeigten Heckklappe gezeigt, die an der Heckklappenanbindung 2 befestigt ist. Ein Richtungspfeil 4 zeigt die Schwenkbewegung des Heckklappe Hügels aus der gezeigten Schließstellung in eine Offenstellung der Heckklappe. figure 1 the closed position of a tailgate, not shown, which is attached to the tailgate connection 2 is shown. A directional arrow 4 shows the pivoting movement of the tailgate hill from the closed position shown to an open position of the tailgate.

Zuletzt ist eine Schnittlinie A-A gezeigt. In der Figur 2 ist eine Draufsicht auf die Schnittlinie A-A gezeigt. Auch dort ist die Karosserieanbindung 1, der Heckklappenbügel 3 und die Heckklappenanbindung 2 zu erkennen. Weiter ist ein Bolzen 5 gezeigt, welcher einends einen Bolzenkopf 11 aufweist.Finally, a cutting line AA is shown. In the figure 2 a plan view of section line AA is shown. The body connection 1, the tailgate bracket 3 and the tailgate connection 2 can also be seen there. A bolt 5 is also shown, which has a bolt head 11 at one end.

Der Bolzen 5 dient dabei der lagernden Halterung des Heckklappen- oder Frontklappenbügels 3 zu der Karosserieanbindung 1.The bolt 5 is used to support the tailgate or front lid bracket 3 to the body connection 1.

In Figur 2 ist gezeigt, wie zwischen der Karosserieanbindung 1 und dem Heckklappen- oder Frontklappenbügel 3 eine Kontaktscheibe 7 angeordnet ist.In figure 2 It is shown how a contact disk 7 is arranged between the body connection 1 and the rear hatch or front hatch bracket 3 .

Die Kontaktscheibe 7 kann dabei ein Federring, eine Wellscheibe, ein Schlitzring, eine Zwischenscheibe oder ein anderes Kreiselement oder Teilkreiselement sein. ä Die Kontaktscheibe 7 ist dabei zwischen dem Kragen 13 und der Karosseriehülse 8 angeordnet, wobei der Kragen 13 wiederum auf der Seite des Bolzens 5 angeordnet ist, welcher auch den Bolzenkopf 11 umfasst. Dadurch ist ein besonders fester Halt gewährleistet und dadurch wiederum ist der Stromfluss in besonders guter Weise gewährleistet.The contact disk 7 can be a spring ring, a corrugated disk, a slotted ring, an intermediate disk or another circular element or partial circular element. The contact disk 7 is arranged between the collar 13 and the body sleeve 8 , the collar 13 in turn being arranged on the side of the bolt 5 which also includes the bolt head 11 . This ensures a particularly firm hold and this in turn ensures the current flow in a particularly good manner.

Außerdem ist ein Kreisbereich B gezeigt, welcher in der Figur 3 vergrößert dargestellt ist.In addition, a circular area B is shown, which in the figure 3 is shown enlarged.

Der Bolzen 5 ist von einer Achse 6 umfangen. Die Achse 6 weist einends einen einstückig ausgebildeten Kragen 13 und andernends eine zusätzliche Drehscheibe 10 auf. Dabei handelt es sich bei der Achse 6 im Wesentlichen um einen Hohlzylinder an dessen einen Ende der Kragen 13 in einem im wesentlich rechten Winkel vom Hohlzylinder weg angeordnet ist.The bolt 5 is encompassed by an axle 6 . The axle 6 has a one-piece collar 13 at one end and an additional rotary disc 10 at the other end. The axis 6 is essentially a hollow cylinder at one end of which the collar 13 is arranged at an essentially right angle away from the hollow cylinder.

Die Achse 6 ist in Arbeitslage von einer Karosseriehülse 8 teilweise oder ganz umgriffen, wobei die Karosseriehülse 8 ein Teil der Karosserieanbindung 1 ist. Das Zusammenspiel aus der Karosseriehülse 8 und der Achse 6 und dem Bolzen 5 führt zu einer leicht definierbaren verschwenkbaren lagernden Halterung für eine solche Lagerstelle.In the working position, the axle 6 is partially or completely encompassed by a body sleeve 8 , the body sleeve 8 being part of the body connection 1 . The interaction of the body sleeve 8 and the axle 6 and the bolt 5 leads to an easily definable, pivotable support for such a bearing point.

Die Kontaktscheibe 7 ist dabei zwischen der Karosseriehülse 8 und dem Kragen 13 zumindest teilweise kontaktend angeordnet ist. Weiter ist in diesem Zusammenhang zu erkennen, wie ein Stromfluss S von der Karosseriehülse 8 der Karosserieanbindung 1 zur Achse 6 und von der Achse 6 zum Bolzen 5 und dann zum Heckklappen- oder Frontklappenbügel 3 verläuft oder, hier nicht gezeigt, von der Achse 6 auf den Heckklappen- oder Frontklappenbügel 3 verläuft. Zuletzt weist die Achse 6 einen Durchlass 14 auf, in welchen der Bolzen 5 in Arbeitsalge eingeschoben ist.The contact disk 7 is arranged at least partially in contact between the body sleeve 8 and the collar 13 . It can also be seen in this context how a current flow S runs from the body sleeve 8 of the body connection 1 to the axis 6 and from the axis 6 to the bolt 5 and then to the tailgate or front lid bracket 3 or, not shown here, from the axis 6 the tailgate or bonnet bar 3 runs. Finally, the axle 6 has a passage 14 into which the bolt 5 is inserted in the work alga.

Weiter ist zwischen der Karosseriehülse 8 und der Achse 6 ein Isolator 9 angeordnet.Furthermore, an insulator 9 is arranged between the body sleeve 8 and the axle 6 .
