Description
Die vorliegende Erfindung betrifft eine Abgasanlage für eine Brennkraftmaschine eines Kraftfahrzeugs mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to an exhaust system for an internal combustion engine of a motor vehicle having the features of the preamble of
Bei zumindest bereichsweise zweiflutigen Abgasanlagen sind zum Abführen von Abgasen der Brennkraftmaschine zwei Abgasstränge vorhanden, die bereichsweise oder vollständig getrennt voneinander verlaufen. Dabei ist jeder Abgasstrang für sich am Fahrzeug aufgehängt. Insbesondere im Bereich von Endrohren kann es erforderlich sein, die beiden Abgasstränge relativ zueinander in einer vorbestimmten Weise zu positionieren, bspw. um für Endrohrblenden eine gewünschte Optik bzw. einen vorbestimmten Abstand gewährleisten zu können. Eine derartige Positionierung der beiden Abgasstränge relativ zueinander kann bspw. mit Hilfe von am Fahrzeug befestigten Konsolen oder Streben realisiert werden. Derartige Konsolen oder Streben erhöhen das Gewicht des Fahrzeugs und können die Abgasstränge auf Biegung belasten, was eine Beschädigungsgefahr mit sich bringen kann.In at least partially double-flow exhaust systems are for discharging exhaust gases of the internal combustion engine, two exhaust gas lines present, which extend partially or completely separated from each other. Each exhaust system is suspended by itself on the vehicle. In particular, in the area of tailpipes, it may be necessary to position the two exhaust strands relative to each other in a predetermined manner, for example to be able to ensure a desired appearance or a predetermined distance for tailpipe trims. Such a positioning of the two exhaust strands relative to one another can be realized, for example, with the aid of brackets or braces fastened to the vehicle. Such consoles or struts increase the weight of the vehicle and can strain the exhaust strands on bending, which can cause a risk of damage.
Eine gattungsgemäße Abgasanlage ist beispielsweise aus der
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Abgasanlage der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie bei einer reduzierten Belastung der Abgasstränge deren Positionierung relativ zueinander vereinfacht.The present invention is concerned with the problem of providing for an exhaust system of the type mentioned in an improved embodiment, which is particularly characterized in that it simplifies their positioning relative to each other with a reduced load on the exhaust strands.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die beiden Abgasstränge mit Hilfe eines Zugelements aufeinander zu vorzuspannen, das zugstabil ist, jedoch gleichzeitig druckschwach und biegeschwach ist. Bei einer entsprechenden Abstützung der Abgasstränge am Fahrzeug ergibt sich durch die von dem wenigstens einen Zugelement erzeugte Vorspannung die gewünschte Lagepositionierung der beiden Abgasstränge relativ zueinander. Dabei kann das Zugelement im Wesentlichen keine Biegekräfte oder Momente über zwischen den Abgassträngen übertragen, wodurch deren Belastung reduziert wird. Ferner kann ein derartiges Zugelement extrem leicht ausgestaltet werden.The invention is based on the general idea of biasing the two exhaust gas strands towards one another with the aid of a tension element that is resistant to tension but at the same time low in pressure and low in bending. With a corresponding support of the exhaust strands on the vehicle, the desired positional positioning of the two exhaust strands relative to each other results from the prestress generated by the at least one tension element. In this case, the tension element can transmit substantially no bending forces or moments over between the exhaust strands, whereby their load is reduced. Furthermore, such a tension element can be designed extremely easily.
Entsprechend einer vorteilhaften Ausführungsform kann das Zugelement eine Feder- und/oder Dämpfereinrichtung aufweisen, die eine Veränderung des Abstands zwischen den Abgassträngen im Bereich des Zugelements gegen Federkraft und/oder gegen Dämpferkraft ermöglicht. Hierdurch lässt das Zugelement Relativbewegungen zwischen den Abgassträngen zu, die jedoch gefedert bzw. gedämpft sind. Derartige Relativbewegungen können bspw. zum Abfangen von Stößen und Erschütterungen entstehen, die während des Fahrbetriebs des Fahrzeugs auftreten können.According to an advantageous embodiment, the tension element may have a spring and / or damper device, which allows a change in the distance between the exhaust strands in the region of the tension element against spring force and / or against damper force. As a result, the tension element allows relative movements between the exhaust strands, which, however, are sprung or damped. Such relative movements may arise, for example, to absorb shocks and vibrations that may occur during the driving operation of the vehicle.
Erfindungsgemäß weist das Zugelement eine Spanneinrichtung auf, die ein Einstellen der die beiden Abgasstränge aufeinander zu antreibenden Vorspannkraft ermöglicht. Eine derartige Spanneinrichtung vereinfacht insbesondere die Montage des Zugelements und somit der Abgasanlage.According to the invention, the tension element has a tensioning device which makes it possible to adjust the pretensioning force which drives the two exhaust gas strands toward one another. Such a clamping device simplifies in particular the assembly of the tension element and thus the exhaust system.

Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
