Description

Die Erfindung betrifft ein Fabrzeughaubenscharnier mit einem Scharnierbügel, der

  • eine Lagerstelle zur gelenkigen Verbindung mit einer Fahrzeugkarosserie und
  • einen Verbindungsabschnitt zur Befestigung an einer Fahrzeughaube aufweist.
The invention relates to a fume hood hinge with a hinge bracket, the
  • a bearing for articulation with a vehicle body and
  • having a connecting portion for attachment to a vehicle hood.

Fahrzeughaubenscharniere der eingangs genannten Art sind in vielfältigen Ausführungsformen aus dem Stand der Technik bekannt. Sie dienen in erster Linie dazu, Fahrzeughaben, wie Motorhauben oder Kofferraumklappen zwischen einer Schließposition und einer Öffnungsposition schwenkbar mit der Fahrzeugkarosserie zu verbinden. Um dabei einen möglichst großen Öffnungswinkel auch bei modern gestalteten Fahrzeugen zu erreichen, weisen die bekannten Fahrzeughaubenscharniere große Scharnierbügel auf, so dass bspw. im Kofferraumbereich eine große Be- und Entladeöffnung erreicht wird. Die hierbei verwendeten Scharnierbügel müssen eine hohe Festigkeit aufweisen und sind üblicherweise aus Stahl gebildet, wodurch sich jedoch ein erheblicher Fertigungsaufwand sowie hohe Kosten und ein hohes Eigengewicht ergibt. Darüber hinaus führen üblicherweise eingesetzte Schweißverfahren oftmals zu hohen Fertigungstoleranzen aufgrund der sich beim Schweißen ergebenden Wärmeausdehnung.Vehicle hood hinges of the type mentioned are known in various embodiments from the prior art. They serve primarily to pivotally connect vehicle hubs, such as hoods or trunk flaps, between a closed position and an open position to the vehicle body. In order to achieve the largest possible opening angle even with modern designed vehicles, the known vehicle hood hinges on large hinge bracket, so that, for example, in the trunk area a large loading and unloading is achieved. The hinge strap used in this case must have a high strength and are usually formed of steel, which, however, results in a significant manufacturing cost and high costs and a high weight. In addition, commonly used welding methods often lead to high manufacturing tolerances due to the resulting during welding thermal expansion.

Zudem sind aus der DE 10 2004 028 009 A1 und der DE 10 2008 031 013 A1 Scharnierbügel aus Kunststoffbzw. einer Kombination aus Metall und Kunststoff bekannt, die ein geringes Eigengewicht aufweisen.In addition, from the DE 10 2004 028 009 A1 and the DE 10 2008 031 013 A1 Hinge bracket made of Kunststoffbzw. a combination of metal and plastic, which have a low weight.

Der Erfindung liegt die Aufgabe zugrunde, ein Fahrzeughaubenscharnier bereitzustellen, das bei gleichzeitig hoher Festigkeit ein nur geringes Eigengewicht aufweist und zudem flexibel in der Herstellung unterschiedlich dimensionierter Scharnierbügel auf der Grundlage einheitlicher, metallischer Basisbauteile ist.The invention has for its object to provide a vehicle hood hinge, which at the same time high strength has only a low weight and also flexible in the production of different sized hinge bracket on the basis of uniform, metallic base components.

Die Erfindung löst die Aufgabe durch ein Fahrzeughaubenscharnier mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The invention achieves the object by a vehicle hood hinge with the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Kennzeichnend für das erfindungsgemäße Fahrzeughaubenscharnier ist, dass der Scharnierbügel des Fahrzeughaubenscharniers zwei in Schwenkachsenrichtung des Scharnierbügels mit der Fahrzeugkarosserie betrachtet im Abstand voneinander angeordnete und aus metallischem Material gebildete Tragkörper aufweist, die zumindest abschnittsweise zur Bildung des Scharnierbügels mit einem die Tragkörper verbindenden Kunststoff ummantelt sind. Gemäß der Erfindung wird der Scharnierbügel somit erst durch die über den Kunststoff hergestellte Verbindung der beiden im Abstand voneinander angeordneten und somit nicht gegeneinander festgelegten Tragkörper hergestellt. Die Tragkörper dienen dabei zur Gewährleistung der erforderlichen Stabilität des Scharnierbügels, wohingegen der Kunststoff mit seinem niedrigen Eigengewicht zur Bildung des Scharnierbügels beiträgt, indem er die Tragkörper relativ zueinander festlegt und zusätzlich stabilisierend wirkt. Die Anordnung der Tragkörper im Abstand voneinander - in Schwenkachsenrichtung des Scharnierbügels mit der Fahrzeugkarosserie betrachtet - gewährleistet dabei, dass der Scharnierbügel eine hohe Widerstandsfähigkeit gegenüber den im Betrieb auftretenden Kräften aufweist.Characteristic of the vehicle hood hinge according to the invention is that the hinge bracket of the vehicle hood hinge two viewed in the pivot axis direction of the hinge bracket with the vehicle body spaced apart and formed of metallic material supporting body, which are at least partially encased to form the hinge bracket with a plastic connecting the support body. According to the invention, the Hinge therefore only made by the connection made over the plastic compound of the two spaced apart and thus not mutually fixed support body. The support body serve to ensure the required stability of the hinge bracket, whereas the plastic with its low weight contributes to the formation of the hinge bracket by fixing the support body relative to each other and additionally acts stabilizing. The arrangement of the support body at a distance from each other - viewed in the pivot axis direction of the hinge bracket with the vehicle body - ensures that the hinge bracket has a high resistance to the forces occurring during operation.

Insgesamt weist der Scharnierbügel und somit auch das Fahrzeughaubenscharnier ein besonders geringes Eigengewicht bei gleichzeitig hoher Festigkeit auf. Der Kunststoff dient darüber hinaus als Dämpfungselement und verhindert besonders wirkungsvoll Klappergeräusch infolge einer Anlage des Scharnierbügels an angrenzenden Bauteilen am Fahrzeug.Overall, the hinge bracket and thus also the vehicle hood hinge has a particularly low weight and high strength. The plastic also serves as a damping element and prevents particularly effective rattling noise due to an investment of the hinge bracket to adjacent components on the vehicle.

Wie bereits eingangs dargelegt kann die relative Festlegung der Tragkörper zueinander allein über die Verwendung des Kunststoffs erfolgen. Nach einer besonders vorteilhaften Weiterbildung der Erfindung sind die Tragkörper jedoch an Verbindungsstellen des Scharnierbügels über Funktionselemente miteinander verbunden. Unter Verbindungsstellen werden dabei im Rahmen der Anmeldung solche Bereiche des Scharnierbügels verstanden, an denen dieser mit angrenzenden Bauteilen des Scharniers oder Fahrzeugs, bspw. der Fahrzeughaube oder Fahrzeugkarosserie oder mit weiteren Funktionselementen, wie bspw. einer Feder verbunden ist. Die Verwendung strukturverstärkender Funktionselemente für diese Bereiche des Scharnierbügels erhöht die Festigkeit des Scharnierbügels in ergänzender Weise und gewährleistet überdies eine sichere Anbindung des Scharnierbügels an angrenzende Bauteile an den entsprechenden Verbindungsstellen. Darüber hinaus ermöglichen die Funktionselemente eine Festlegung der Tragkörper relativ zueinander, so dass bspw. ein nachfolgender Kunststoffspritzvorgang besonders einfach durchgeführt werden kann, da auf eine Festlegung der Tragkörper zueinander verzichtet werden kann.As already stated at the outset, the relative fixing of the supporting bodies to one another can be effected solely by the use of the plastic. According to a particularly advantageous embodiment of the invention, however, the support body are connected to each other at connection points of the hinge bracket via functional elements. In the context of the application, connection areas are understood to mean those areas of the hinge bracket where it is connected to adjacent components of the hinge or vehicle, for example the vehicle hood or vehicle body, or to other functional elements such as a spring. The use of structural reinforcing functional elements for these areas of the hinge bracket increases the strength of the hinge bracket in a complementary manner and also ensures a secure connection of the hinge bracket to adjacent components at the corresponding connection points. In addition, the functional elements allow a determination of the support body relative to each other, so that, for example, a subsequent plastic injection process can be carried out particularly easily, since it can be dispensed with a determination of the support body to each other.

Die Ausgestaltung der Tragkörper und/oder der Funktionselemente insbesondere die zu deren Herstellung verwendeten Materialen kann entsprechend der gestellten Anforderungen frei gewählt werden, wobei bspw., jedoch nicht erfindungsgemäß, auch aus Kohlefaser hergestellte Tragkörper verwendet werden können, welche ein besonders geringes Eigengewicht des Scharnierbügels ermöglichen. Nach einer vorteilhaften Weiterbildung der Erfindung sind die Funktionselemente jedoch aus einem metallischen Werkstoff gebildet. Die Verwendung metallischer Werkstoffe zur Herstellung der Tragkörper und Funktionselemente, bspw. die Verwendung von Aluminiumlegierungen gewährleistet eine hohe Festigkeit des Scharnierbügels bei gleichzeitig niedrigen Herstellungskosten. Die Verwendung leichter metallischer Werkstoffe, wie bspw. die Verwendung von Aluminiumlegierungen ermöglicht es darüber hinaus, das Eigengewicht des Scharnierbügels in ergänzender Weise zu senken. Im Falle der Verwendung von Funktionselementen können diese grundsätzlich in beliebiger Weise mit den Tragkörpern verbunden werden, wobei vorzugsweise nicht thermische Fügeverfahren, bspw. die Verbindung über Schrauben oder Niete gewählt werden, die die Herstellung mit nur geringen Fertigungstoleranzen ermöglicht.The design of the support body and / or the functional elements, in particular the materials used for their production can be chosen freely according to the requirements, for example, but not according to the invention, also made of carbon fiber supporting body can be used, which allow a particularly low weight of the hinge bracket , According to an advantageous embodiment of the invention, however, the functional elements are formed of a metallic material. The use of metallic materials for the production of the supporting bodies and functional elements, for example the use of aluminum alloys, ensures a high strength of the hinge bracket with simultaneously low production costs. The use of light metallic materials, such as, for example, the use of aluminum alloys also makes it possible to reduce the dead weight of the hinge bracket in a complementary manner. In the case of the use of functional elements they can in principle be connected in any way with the support bodies, preferably non-thermal joining methods, for example. The connection can be selected by screws or rivets, which allows the production with only small manufacturing tolerances.

Die Anordnung des Kunststoffes an dem Tragkörper und/oder den Funktionselementen kann ebenfalls in beliebiger Weise erfolgen. So besteht bspw. die Möglichkeit, die Tragkörper und ggf. die Funktionselemente in einen bereits ausgeformten Kunststoffkörper form- und/oder stoffschlüssig einzusetzen, um so den Scharnierbügel zu bilden. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung sind die Tragkörper und/oder die Funktionselemente jedoch mit Kunststoff umspritzt. Ein derart ausgebildeter Scharnierbügel lässt sich besonders einfach und kostengünstig herstellen. Darüber hinaus können im Kunststoffspritzprozess gezielt einzelne Bereiche ausgewählt werden, die mit Kunststoff umspritzt werden, wohingegen andere Bereiche frei bleiben können.The arrangement of the plastic on the support body and / or the functional elements can also be done in any way. For example, there is the possibility of form-fitting and / or material-locking use of the support body and possibly the functional elements in an already formed plastic body, so as to form the hinge bracket. According to a particularly advantageous embodiment of the invention, however, the supporting body and / or the functional elements are encapsulated in plastic. Such a trained hinge bracket can be particularly easy and inexpensive to produce. In addition, individual areas can be selected in the plastic injection process, which are encapsulated with plastic, whereas other areas can remain free.

Die Ausgestaltung der Lagerstelle, welche zur gelenkigen Verbindung der Fahrzeughaube mit einer an der Karosserie angeordneten Halterung in Eingriff bringbar ist, kann in beliebiger Weise unter Berücksichtigung der jeweiligen Anforderungen erfolgen. Nach einer besonders vorteilhaften Ausgestaltung ist die Lagerstelle jedoch durch ein die Tragkörper verbindenden Metallkörper gebildet, welcher mit einem Lagereigenschaften aufweisenden Kunststoff umspritzt ist. Unter einem Lagereigenschaften aufweisenden Kunststoff werden dabei solche Kunststoffe verstanden, die gute Gleiteigenschaften bei nur geringem Verschleiß aufweisen. Die Verwendung eines derartigen Kunststoffs gewährleistet einen zuverlässigen Betrieb und verhindert in besonders zuverlässiger Weise eine Geräuschentwicklung aufgrund von Relativbewegungen der Lagerstelle gegenüber der entsprechenden Aufnahme.The design of the bearing point, which can be brought to the articulated connection of the vehicle hood with a body arranged on the holder in engagement, can be done in any way, taking into account the respective requirements. According to a particularly advantageous embodiment, however, the bearing is formed by a metal body connecting the support body, which is encapsulated with a bearing properties having plastic. Under a bearing properties having plastic are understood to mean those plastics which have good sliding properties with little wear. The use of such a plastic ensures reliable operation and prevents in a particularly reliable manner a noise due to relative movements of the bearing against the corresponding recording.

Die Ausgestaltung der Tragkörper, welche dem Scharnierbügel die grundsätzliche Stabilität verleihen, kann grundsätzlich entsprechend der bestehenden Anforderungen frei gewählt werden. Nach einer vorteilhaften Ausgestaltung der Erfindung sind die Tragkörper jedoch durch ebene Metallkörper gebildet, die senkrecht zur Schwenkachse betrachtet, parallel im Abstand voneinander angeordnet sind. Die Verwendung derart ausgestalteter Tragkörper bspw. in Form von speziell ausgestalteten flachen Metallblechen weist den Vorteil auf, dass der durch diese Tragkörper gebildete Scharnierbügel eine hohe Widerstandsfähigkeit gegenüber den im Betrieb auftretenden Belastungen, gleichzeitig jedoch nur ein geringes Eigengewicht aufweist. Darüber hinaus bietet die Verwendung derartiger Tragkörper die Möglichkeit einer einfachen Anordnung angespritzter oder angesetzter Kunststoffelemente.The design of the support body, which the hinge bracket the basic stability can basically be freely selected according to the existing requirements. According to an advantageous embodiment of the invention, however, the support body are formed by planar metal body, which are considered perpendicular to the pivot axis, are arranged parallel spaced from each other. The use of such configured support body eg. In the form of specially designed flat metal sheets has the advantage that the hinge bracket formed by this support has a high resistance to the loads occurring during operation, but at the same time only a small weight. In addition, the use of such support body offers the possibility of a simple arrangement of molded or attached plastic elements.

Ein Ausführungsbeispiel der Erfindung wird nachstehend mit Bezug auf die Zeichnungen erläutert. In den Zeichnungen zeigen:

inside the hinge hanger of Fig. 1 arranged support body in a perspective view.

In Fig. 1 ist in einer perspektivischen Darstellung eine Ausführungsform eines Scharnierbügels 1 eines hier nicht dargestellten Fahrzeughaubenscharniers dargstellt. Der Scharnierbügel 1 weist, die in Fig. 2 ebenfalls in einer perspektivischen Darstellung abgebildeten Tragkörper 2a, 2b auf, die aus flachen metallischen Abschnitten gebildet sind. Die Tragkörper 2a, 2b sind dabei senkrecht zu einer Schwenkachse A und parallel zueinander im Abstand voneinander angeordnet. Der Abstand der Tragkörper 2a, 2b ist durch in unterschiedlichen Abschnitten an den Tragkörpern 2a, 2b angeordnete Funktionselemente festgelegt, wobei als Funktionselemente eine Lagerachse 7, Befestigungsaufnahmen 8 zur Anbindung des Scharnierbügels 1 an einer Fahrzeughaube und einer Federeinhängung 9 vorhanden sind.In Fig. 1 is a perspective view of an embodiment of a hinge bracket 1 dargstellt a vehicle hood hinge, not shown here. The hinge bracket 1 has, in Fig. 2 also shown in a perspective view supporting body 2a, 2b, which are formed from flat metallic sections. The support bodies 2a, 2b are arranged perpendicular to a pivot axis A and parallel to each other at a distance from each other. The distance between the supporting bodies 2a, 2b is determined by functional elements arranged in different sections on the supporting bodies 2a, 2b, wherein a bearing axis 7, fastening receptacles 8 for connecting the hinge bracket 1 to a vehicle hood and a spring suspension 9 are present as functional elements.

Die Funktionselemente beabstanden die Tragkörper 2a, 2b und erhöhen zudem die Steifigkeit des Scharnierbügels 1. Die Funktionselemente 7, 8, 9 stellen Verbindungsstellen 3, 5, 6 dar, an welchen der Scharnierbügel 1 mit angrenzenden Bauteilen des Haubenscharniers oder weiterer Bauteile verbunden ist.The functional elements space the supporting bodies 2a, 2b and also increase the rigidity of the hinge bracket 1. The functional elements 7, 8, 9 represent connection points 3, 5, 6 to which the hinge bracket 1 is connected to adjacent components of the hood hinge or other components.

So dienen die Aufnahmen 8 zur starren Verbindung des Scharnierbügels 1 an einer hier nicht dargestellten Fahrzeughaube, wohingegen die Lagerachse 7 zur drehgelenkigen Anordnung des Scharnierbügels 1 an einer entsprechenden, hier ebenfalls nicht dargestellten, Aufnahme an der Karosserie vorgesehen ist. Die Federeinhängung 9 ermöglicht die Anordnung eines Federelements, welche eine Vorspannung der mit dem Scharnierbügel 1 angebunden Haube in eine Öffnungs- und oder Schließlage ermöglicht.Thus, the receptacles 8 are used for rigid connection of the hinge bracket 1 to a vehicle hood, not shown here, whereas the bearing shaft 7 for pivotally mounted arrangement of the hinge bracket 1 at a corresponding, also not shown here, Recording is provided on the body. The suspension spring 9 allows the arrangement of a spring element, which allows a bias of the tailpiece connected to the hinge bracket 1 in an open and or closed position.

Die Tragkörper 2a, 2b sind durch einen Kunststoffkörper 4 zumindest teilweise ummantelt, wobei der Kunststoffkörper 4 dem Scharnierbügel 1 eine zusätzliche Stabilität verleiht sowie gleichzeitig als Dämpfungselement fungiert. Darüber hinaus weist der Kunststoffkörper 4 zur Erhöhung der Stabilität quer zu den Tragkörpern 2a, 2b verlaufende Querrippen 10 auf. Die Lagerachse 7 ist überdies mit einem gleitfähigen Kunststoffbeschichtet, um so eine gute Verschwenkbarkeit des Scharnierbügels 1 an der entsprechenden Aufnahme des Fahrzeughaubenscharniers zu gewährleisten.The support bodies 2a, 2b are at least partially encased by a plastic body 4, wherein the plastic body 4 gives the hinge bracket 1 additional stability and at the same time acts as a damping element. In addition, the plastic body 4 to increase the stability transverse to the support bodies 2a, 2b extending transverse ribs 10. The bearing shaft 7 is also coated with a lubricious plastic, so as to ensure a good pivoting of the hinge bracket 1 to the corresponding receptacle of the vehicle hood hinge.
