Description

Die Erfindung bezieht sich auf ein Endrohr für ein Abgasrohr einer Abgasanlage eines Kraftfahrzeuges nach dem Oberbegriff des Anspruchs 1.The invention relates to an end pipe for an exhaust pipe of an exhaust system Motor vehicle according to the preamble of claim 1.

Es sind Endrohre für Abgasrohre von Abgasanlagen bekannt, die einschalig ausgebildet sind und auf das freie Ende des Abgasrohres aufgesteckt werden. Die Wandung des Endrohres liegt unmittelbar auf dem Abgasrohr auf.End pipes for exhaust pipes from exhaust systems are known which have a single shell are formed and placed on the free end of the exhaust pipe. The Wall of the tailpipe lies directly on the exhaust pipe.

Die Aufgabe der Erfindung besteht darin, ein Endrohr für ein Abgasrohr einer Abgasanlage zu schaffen, mit dem eine verbesserte Wärme- und Luftabfuhr gewährleistet ist.The object of the invention is an end pipe for an exhaust pipe To create exhaust system with which improved heat and air dissipation is guaranteed.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the features of claim 1. The dependent claims contain further advantageous features.

Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß eine gezielte Wärmeabfuhr im Bereich des freien hinteren Endes des Abgasrohres durch Luftzirkulation erzielbar ist. Hierzu wird das Endrohr doppelwandig mit einer Außen- und Innenschale ausgeführt, die beabstandet zueinander angeordnet sind und zwischen sich einen Luftspalt aufweisen. Eine Befestigung der Innenschale mit der Außenschale erfolgt vorzugsweise am Mündungsrand des Endrohres. Eine andere Befestigung ist auch denkbar. Das Endrohr ist lösbar mit dem freien Ende des Abgasrohres verbindbar, wozu Schrauben verwendet werden, die ein Verklemmen mit dem Abgasrohr bewirken.The main advantages achieved with the invention are that a targeted Heat dissipation in the area of the free rear end of the exhaust pipe Air circulation can be achieved. For this, the tailpipe is double-walled with an outer and Inner shell executed, which are spaced from each other and between have an air gap. A fastening of the inner shell with the outer shell is preferably carried out at the mouth of the tailpipe. Another attachment is also conceivable. The end pipe is detachable with the free end of the exhaust pipe connectable, which uses screws that jam with the Cause exhaust pipe.

Zur definierten Luftzirkulation im Spaltraum zwischen den beiden Schalen, sind diese rundherum beabstandet zueinander angeordnet und nur im Mündungsrand der Außenschale miteinander, z.B. durch eine Schweißung verbunden. These are for the defined air circulation in the gap between the two shells all around spaced apart and only in the mouth of the Outer shell with each other, e.g. connected by a weld.

In der Innenschale sind Durchbrechungen vorgesehen, die eine Umspülung des eingesteckten Abgasrohres mit Fahrtwind bewirken sollen, damit die Außenschale nicht zu heiß wird und nahegelegene Kunststoffteile nicht durch Wärmeabstrahlung beschädigt werden oder aber auch die verchromte Außenschale nicht durch die auftretende Wärme zerstört wird.Openings are provided in the inner shell, which allow the water to be washed around inserted exhaust pipe with head wind should cause the outer shell does not get too hot, and nearby plastic parts do not get radiated by heat or the chrome-plated outer shell is not damaged by the occurring heat is destroyed.

Die zwischen den beiden Schalenteilen einströmende Luft kann über gezielt angeordnete schlitzartige Öffnungen im Mündungsrand des Endrohres nach außen abgeleitet werden, wobei aufgrund des im Mündungsbereich herrschenden Unterdruckes ein sogenannter Jet-Effekt erzielt wird. Hierdurch wird die zwischen den beiden Schalen einströmende Luft förmlich herausgesogen, wodurch ein maximaler Luftdurchsatz und somit eine optimale Wärmeabfuhr und Temperaturabsenkung am Abgasrohr erzielt wird.The air flowing in between the two shell parts can be targeted arranged slot-like openings in the mouth of the tailpipe to the outside are derived, due to the prevailing in the mouth area A so-called jet effect is achieved. As a result, the between the Air flowing in from both shells is literally sucked out, creating a maximum Air flow and thus optimal heat dissipation and temperature reduction on Exhaust pipe is achieved.

Die Öffnungen im Bereich des Mündungsrandes können auch nur zwischen den Verbindungsschweißungen der beiden Schalen gebildet werden, in dem ein geringer Spaltabstand vom Rand der Innenschale zum Mündungsrand der Außenschale hergestellt wird.The openings in the area of the mouth edge can only between the Connection welds of the two shells are formed in a small Gap distance from the edge of the inner shell to the mouth edge of the outer shell will be produced.

In der Innenschale sind längs- und querverlaufende, nach innen vorstehende Sicken vorgesehen, auf denen sich das Endrohr abstützt, so daß keine durchgehende flächige Anlage an der Innenschale durch das Abgasrohr erfolgt. Vorzugsweise sind zwei mit Abstand zueinander vorgesehene Sicken, die zwischen sich die Durchbrüche aufweisen, in der Innenschale angeordnet.In the inner shell there are longitudinal and transverse beads that protrude inwards provided on which the tail pipe is supported so that no continuous flat Attachment to the inner shell through the exhaust pipe. Preferably two are with Spacing between the beads, the breakthroughs between them have arranged in the inner shell.

Durch die Doppelwandigkeit des Endrohres zirkuliert Luft im Luftspaltraum der beiden Schalen. Dadurch wird eine verbesserte Luftabführung erzielt. Durch die zusätzlichen seitlichen, am Mündungsrand umlaufenden angebrachten Schlitze wird mehr Luft durchgesetzt. Durch den Sog an der hinteren Kante des Endrohres entsteht der sogenannte Düsen/Jet-Effekt, d.h. mehr Luft wird durch den Luftspalt zwischen den beiden Schalen gezogen. Dies bewirkt eine gute Temperaturabsenkung durch eine optimale Luftführung.Due to the double-walled end pipe, air circulates in the air gap between the two Peel. This results in an improved air discharge. Through the additional There is more air on the side of the slots that run around the edge of the mouth enforced. The suction at the rear edge of the tailpipe creates the so-called nozzle / jet effect, i.e. more air is created through the air gap between the pulled both shells. This brings about a good temperature reduction through a optimal airflow.
