Abstract
Description
Die Erfindung betrifft eine Endrohrblende für eine Abgasleitung eines Kraftwagens nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a tailpipe for an exhaust pipe of a motor vehicle according to the preamble of claim 1.
Aus optischen Gründen ist es bei Kraftwagen, insbesondere bei Personenkraftwagen, bisweilen erwünscht, das Endrohr einer Abgasleitung des Kraftwagens in einen Stoßfänger zu integrieren. Hierbei ist es ebenfalls wünschenswert, dass zwischen einer Aussparung des Stoßfängers und dem Endrohr bzw. einer Endrohrblende ein möglichst geringer Spalt vorhanden ist.Out optical reasons it is sometimes in motor vehicles, especially passenger cars, sometimes he wishes, the tailpipe of an exhaust pipe of the motor vehicle in a bumper too integrate. Here it is also desirable that between a Recess of the bumper and the tailpipe or a tailpipe aperture the smallest possible gap available is.
Da die Abgasleitung des Kraftwagens jedoch stets Erschütterungen ausgesetzt ist, die insbesondere beim Anlassen des Motors auftreten, muss der Spalt zwischen dem Stoßfänger und dem Endrohr bzw. der Endrohrblende ausreichend groß ausgestaltet sein, was aus optischen Gründen nicht wünschenswert ist.There However, the exhaust pipe of the motor vehicle always vibrations is exposed, especially when starting the engine, must be the gap between the bumper and designed the tailpipe or the tailpipe aperture sufficiently large be, for visual reasons not desirable is.
Die
Die Aufgabe der Erfindung besteht darin, eine Endrohrblende bereitzustellen, die gegenüber dem Stand der Technik eine technisch einfachere Verbindung mit dem Stoßfänger erlaubt und gleichzeitig kostengünstiger herzustellen ist.The The object of the invention is to provide a tailpipe trim, the opposite to the The prior art allows a technically easier connection with the bumper and at the same time cheaper is to produce.
Die Lösung der Aufgabe besteht in einer Endrohrblende für eine Abgasleitung eines Kraftwagens mit den Merkmalen des Patentanspruchs 1.The solution the task consists in a tailpipe for an exhaust pipe of a motor vehicle with the features of claim 1.
Die Endrohrblende für eine Abgasleitung eines Kraftwagens nach Patentanspruch 1 ist im Bereich eines Stoßfängers angeordnet. Hierbei ist im Stoßfänger eine Auspufföffnung vorgesehen, durch die die Endrohrblende nach außen ragt. Die Endrohrblende ist am Stoßfänger befestigt. Weiterhin ist ein Endrohr der Abgasleitung in der Art in die Endrohrblende eingeführt, dass zwischen der Endrohrblende und dem Endrohr ein Spalt vorherrscht. Die Erfindung zeichnet sich dadurch aus, dass die Endrohrblende aus einem hochtemperaturbeständigen Kunststoff besteht.The Tailpipe for an exhaust pipe of a motor vehicle according to claim 1 is in Area of a bumper arranged. Here is a bumper in the exhaust port provided through which the tailpipe aperture protrudes outward. The tailpipe trim is attached to the bumper. Furthermore, an end pipe of the exhaust pipe in the manner in the tailpipe introduced, that there is a gap between the tailpipe baffle and the tailpipe. The invention is characterized in that the tailpipe aperture made of a high temperature resistant plastic consists.
Durch die Anwendung eines hochtemperaturbeständigen Kunststoffes wird die Endrohrblende in ihrer Herstellung an sich kostengünstiger. Ferner wird durch die Anwendung eines hochtemperaturbeständigen Kunststoffes das Gewicht der Endrohrblende gegenüber dem Stand der Technik, wo eine metallische Endrohrblende angewendet wird, deutlich reduziert, was wiederum eine leichtere und technisch einfachere und hiermit wiederum kostengünstigere Aufhängung der Endrohrblende am Stoßfänger ermöglicht.By the application of a high temperature resistant plastic is the Tailpipe in their production itself more cost-effective. Furthermore, by the application of a high temperature resistant plastic the weight of the tailpipe trim over the prior art, where a metallic tailpipe trim is used, significantly reduced, which in turn is a lighter and technically simpler and hereby again cheaper suspension allows the tailpipe trim on the bumper.
In einer Ausgestaltungsform der Erfindung ist der Kunststoff der Endrohrblende verchrombar ausgestaltet. Das Verchromen des Kunststoffes ist aus optischen Gründen vorteilhaft. Es ist aus Haftungsgründen grundsätzlich nicht jeder Kunststoff zum Verchromen geeignet. Besonders geeignet zum Verchromen und ebenfalls hochtemperaturbeständig, sind Kunststoffe auf der Basis von Polyphenylensulfid und flüssigkristallinen Polymeren (LPC). Kunststoffe dieser Klasse haben sich als geeignet zur Verwendung von Endrohrblenden erwiesen.In an embodiment of the invention is the plastic of the tailpipe chromed designed. The chrome plating of the plastic is out optical reasons advantageous. It is for liability reasons not every plastic for Chrome plating suitable. Especially suitable for chrome plating and also high temperature resistant, are plastics based on polyphenylene sulfide and liquid crystalline ones Polymers (LPC). Plastics of this class have proven to be suitable proved to use tailpipe trims.
Zwischen der Endrohrblende und dem Rand einer Auspufföffnung im Stoßfänger besteht bevorzugt ein Spalt. Dieser Spalt ist häufig aus Gründen des Designs einerseits gewollt, andererseits sollte er wiederum möglichst schmal, beispielsweise geringer als 10 mm, ausgestaltet sein.Between the tailpipe trim and the edge of an exhaust port in the bumper preferably a gap. This gap is often for the sake of design on the one hand wanted, on the other hand, he should turn as narrow as possible, for example less than 10 mm, be configured.
Es hat sich als zweckmäßig herausgestellt, die Endrohrblende durch eine Steckverbindung oder durch eine Clipverbindung am Stoßfänger zu befestigen. Hierbei können Clip- und Steckverbindungen auch nebeneinander vorliegen oder ineinander integriert sein.It has proved to be useful, the Tailpipe trim by a plug connection or by a clip connection at the bumper too Fasten. Here you can Clip and plug connections are also present next to each other or into each other be integrated.
Bevorzugte Ausgestaltungsformen der Erfindung werden anhand der folgenden Figuren näher erläutert.preferred Embodiments of the invention will become apparent from the following figures explained in more detail.
Die einzige Figur zeigt einen Querschnitt durch einen Stoßfänger mit einer Endrohrblende und ein in die Endrohrblende eingefügtes Endrohr.The single figure shows a cross section through a bumper with a tailpipe baffle and a tailpipe inserted into the tailpipe baffle.
