Description
Die Erfindung betrifft ein Lufteinlassgitter für einen Kraftwagen der im Oberbegriff des Patentanspruchs 1 angegeben Art. Des Weiteren betrifft die Erfindung ein Verfahren zum Herstellen eines Lufteinlassgitters für einen Kraftwagen.The invention relates to an air intake grille for a motor vehicle of the type specified in the preamble of patent claim 1. Furthermore, the invention relates to a method for producing an air intake grille for a motor vehicle.
Ein gattungsgemäßes Lufteinlassgitter ist aus der
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Lufteinlassgitter der eingangs genannten Art sowie ein Verfahren zum Herstellen eines solchen Lufteinlassgitters bereitzustellen, mittels welchen eine Sicht auf hinter dem Lufteinlassgitter liegende Aggregate durch außenstehende Betrachter verhindert und gleichzeitig eine ausreichend gute Anströmung dieser Komponenten ermöglicht wird.It is therefore the object of the present invention to provide an air inlet grille of the type mentioned above and a method for producing such an air inlet grille, by means of which a view of lying behind the air inlet grille units prevented by outside observers and at the same time a sufficiently good flow of these components is possible.
Diese Aufgabe wird durch ein Lufteinlassgitter für einen Kraftwagen mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren zum Herstellen eines Lufteinlassgitters mit den Merkmalen des Patentanspruchs 5 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by an air intake grille for a motor vehicle having the features of patent claim 1 and by a method for producing an air intake grille having the features of patent claim 5. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.
Um zu verhindern, dass hinter dem Lufteinlassgitter angeordnete Aggregate durch außenstehende Betrachter sichtbar sind und gleichzeitig eine ausreichend gute Anströmung dieser Komponenten gewährleistet wird, ist es bei einem erfindungsgemäßen Lufteinlassgitter vorgesehen, dass sich an den parallel ausgerichteten Teil jeweils ein Teil anschließt, welcher gegenüber der aus der Fahrzeuglängsrichtung und Fahrzeugquerrichtung aufgespannten Ebene um einen vorgegebenen Winkel um die Fahrzeugquerrichtung geneigt ist. Mit anderen Worten werden also die Durchgangsöffnungen des Lufteinlassgitters in der Längserstreckung mit einem horizontalen und zumindest einem sich an diesen anschließenden, um die Fahrzeugquerachse gekippten Abschnitt ausgebildet. Aufgrund der Kippung der jeweiligen Öffnungsabschnitte wird dem außenstehenden Betrachter die Sicht auf hinter dem Lufteinlassgitter liegende Aggregate, wie beispielsweise Ladeluftkühler oder dergleichen, verwehrt, so dass im eingebauten Zustand des Lufteinlassgitters am Kraftwagen einem Betrachter eine optisch verbesserte Anmutung entgegengebracht wird. Nichtsdestotrotz wird aufgrund der parallel ausgerichteten Teile der Durchgangsöffnungen eine ausreichend gute Anströmung der hinter dem Gitter liegenden Aggregate gewährleistet.In order to prevent arranged behind the air intake grille units are visible by outside observers and at the same time a sufficiently good flow of these components is ensured, it is provided in an air inlet grille according to the invention, that in each case a part adjoins the parallel aligned part, which opposite to the the vehicle longitudinal direction and vehicle transverse direction plane spanned by a predetermined angle about the vehicle transverse direction is inclined. In other words, therefore, the passage openings of the air inlet grille are formed in the longitudinal extent with a horizontal and at least one subsequent to this, tilted about the vehicle transverse axis portion. Due to the tilting of the respective opening sections, the outside observer is prevented from looking at aggregates located behind the air inlet grille, such as intercoolers or the like, so that when the air intake grille is installed on the motor vehicle, a viewer is given an optically improved appearance. Nevertheless, due to the parallel aligned parts of the passage openings a sufficiently good flow of the lying behind the grid aggregates is ensured.
In vorteilhafter Ausgestaltung der Erfindung ist es vorgesehen, dass der geneigte Teil in Fahrzeuglängsrichtung jeweils hinter dem parallel ausgerichteten Teil angeordnet ist, wobei der geneigte Teil gegenüber dem parallelen Teil in Fahrzeughochrichtung nach oben geneigt ist. Dadurch wird die Luftanströmung hinter dem Ladeluftgitter angeordneter Aggregate bzw. deren Kühlung besonders wenig beeinträchtigt und ist einer Durchgangsöffnung mit durchgängig horizontalem Verlauf im Wesentlichen nahezu gleichzusetzen.In an advantageous embodiment of the invention, it is provided that the inclined part is arranged in the vehicle longitudinal direction in each case behind the parallel-aligned part, wherein the inclined part is inclined relative to the parallel part in the vehicle vertical direction upwards. As a result, the air flow behind the charge air grille arranged units or their cooling is particularly little affected and is substantially equivalent to a through hole with a continuous horizontal course substantially.
In einer besonders bevorzugten Ausführungsform der Erfindung ist es vorgesehen, dass der Winkel zwischen 10 und 40° beträgt. Dadurch wird eine besonders gute Verdeckung der hinter dem Lufteinlassgitter angeordneten Aggregate erreicht und zum anderen wird nach wie vor eine ausreichend gute Anströmung und somit auch Kühlung dieser Aggregate erzielt.In a particularly preferred embodiment of the invention, it is provided that the angle is between 10 and 40 °. As a result, a particularly good coverage of the arranged behind the air intake grille units is achieved and on the other hand, a sufficiently good flow and thus cooling of these units is still achieved.
Eine weitere vorteilhafte Ausführungsform der Erfindung sieht vor, dass das Lufteinlassgitter aus einem Kunststoff ausgebildet ist. Zum einen kann das Lufteinlassgitter dadurch besonders leichtgewichtig ausgebildet werden, und zum anderen kann ein aus einem Kunststoff ausgebildetes Lufteinlassgitter besonders einfach mit der gewünschten Geometrie hergestellt werden, so dass eine möglichst gute Verdeckung der besagten Aggregate bei einer gleichzeitig guten Anströmbarkeit erzielt werden kann.A further advantageous embodiment of the invention provides that the air inlet grille is formed from a plastic. On the one hand, the air inlet grille can thereby be designed to be particularly lightweight, and on the other hand, a formed of a plastic air inlet grille can be particularly easily produced with the desired geometry, so that the best possible concealment of said aggregates can be achieved with a good flowability at the same time.
Ein erfindungsgemäßes Verfahren zum Herstellen, insbesondere Spritzgießen, eines Lufteinlassgitters für einen Kraftwagen umfasst die folgenden Schritte:
- – Einspritzen eines Kunststoffs in eine Kavität eines Werkzeugs;
- – Öffnen des Werkzeugs, wobei jeweilige an einer ersten Werkzeughälfte angeordnete und an dem Lufteinlassgitter anliegende Schieber in die gleiche Richtung bewegt werden wie eine zweite Werkzeughälfte, an welcher das Lufteinlassgitter anhaftet;
- – Wegbewegen der Schieber von dem Lufteinlassgitter, wobei die Schieber in die gleiche Richtung bewegt werden, wie jeweilige schräg angestellte Teile jeweiliger Durchgangsöffnungen des Lufteinlassgitters ausgerichtet sind;
- – Entformen des Lufteinlassgitters von der zweiten Werkzeughälfte.
- - injecting a plastic into a cavity of a tool;
- - opening the tool, wherein respective arranged on a first mold half and fitting the air inlet grille slider are moved in the same direction as a second mold half to which the air inlet grille adheres;
- Moving the slides away from the air inlet grille, wherein the slides are moved in the same direction as respective obliquely set parts of respective through openings of the air inlet grille are aligned;
- - Removing the air inlet grille from the second mold half.
Mit anderen Worten wird erfindungsgemäß nach einem abgeschlossenen Spritzgießvorgang zunächst das Werkzeug geöffnet, wobei die Schieber die Bewegung der sich abhebenden Werkzeughälfte mitmachen, so dass die schräge bzw. gekippte Öffnungskonstruktion des Lufteinlassgitters nicht beschädigt wird. Ferner wird bei vollständig geöffnetem Werkzeug ermöglicht, dass die Schieber gemäß dem Kippwinkel der Öffnungen des Lufteinlassgitters eine solche Bewegung ausführen können, so dass die Durchgangsöffnungen aus den zuvor innerhalb der Schieber angeordneten Stirnseiten herausgleiten können, ohne dass die Durchgangsöffnungen beschädigt werden. In other words, according to the invention, after a completed injection molding operation, first the tool is opened, wherein the slides join in the movement of the lifting mold half, so that the oblique or tilted opening construction of the air inlet grille is not damaged. Further, when the tool is fully opened, it is possible for the sliders to make such movement according to the tilt angle of the openings of the air inlet grille, so that the through holes can slide out of the end faces previously located inside the sliders without damaging the through holes.
In vorteilhafter Ausgestaltung des Verfahrens ist es vorgesehen, dass die Schieber hydraulisch, pneumatisch, elektrisch oder federbelastet beim Öffnen des Werkzeugs bewegt werden. Dadurch kann die Bewegung der Schieber während der Öffnung des Werkzeugs besonders gut gesteuert werden, so dass einer Beschädigung des Lufteinlassgitters, insbesondere eine Beschädigung von dessen Durchgangsöffnungen, verhindert werden kann.In an advantageous embodiment of the method, it is provided that the slides are moved hydraulically, pneumatically, electrically or spring loaded when opening the tool. Thereby, the movement of the slide can be particularly well controlled during the opening of the tool, so that damage to the air inlet grille, in particular damage to the through holes, can be prevented.
