Abstract
Die Erfindung betrifft eine Abgasanlage (1) für oder an einem Kraftfahrzeug, mit zwei Abgassträngen (2, 3) zum Abführen von Abgasen einer Brennkraftmaschine des Fahrzeugs, wobei jeder Abgasstrang (2, 3) am Fahrzeug aufgehängt ist. Zur Positionierung der beiden Abgasstränge (2, 3) relativ zueinander ist zumindest ein druckschwaches, biegeschwaches und zugstabiles Zugelement (6) vorgesehen, das die beiden Abgasstränge (2, 3) aufeinander zu vorspannt.The invention relates to an exhaust system (1) for or on a motor vehicle, with two exhaust lines (2, 3) for discharging exhaust gases of an internal combustion engine of the vehicle, wherein each exhaust line (2, 3) is suspended on the vehicle. For positioning the two exhaust gas strands (2, 3) relative to each other, at least one low-pressure, low-bending and tension-resistant tension element (6) is provided, which biases the two exhaust gas strands (2, 3) toward one another.
Description
Die vorliegende Erfindung betrifft eine Abgasanlage für eine Brennkraftmaschine eines Kraftfahrzeugs.The The present invention relates to an exhaust system for an internal combustion engine of a motor vehicle.
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.at at least partially double-flow exhaust systems are for discharging Exhaust gases of the internal combustion engine two exhaust gas lines present in some areas or completely separated from each other. Each exhaust system is on its own Vehicle hung up. Especially in the area of tailpipes, it may be necessary the two exhaust pipes relative to one another in a predetermined manner, for example, for Tailpipes a desired Optics or to ensure a predetermined distance. Such Positioning of the two exhaust strands relative to each other can For example, with the help of mounted on the vehicle brackets or struts will be realized. Such consoles or struts increase that Weight of the vehicle and can the exhaust pipes load on bending, which is a risk of damage can.
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 employs dealing with the problem, for an exhaust system of the type mentioned an improved embodiment particular distinguishing themselves by the fact that they a reduced load on the exhaust strands their positioning relative simplified to each other.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively the subject of the independent Claim solved. 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, the two exhaust strands with Help a tensile element to bias each other, the zugstabil is, but at the same time pressure-weak and low-bending. at a corresponding support the exhaust strands on the vehicle results from that of the at least one tension element generated bias the desired Position positioning of the two exhaust lines relative to each other. there the tension element can essentially no bending forces or Moments over transmitted between the exhaust pipes, whereby their load is reduced. Furthermore, such a Tensile element are made extremely lightweight.
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.Corresponding an advantageous embodiment the tension element can have a spring and / or damper device, the one change the distance between the exhaust strands in the region of the tension element against spring force and / or against damper force allows. This leaves the tension element relative movements between the exhaust strands, but sprung or dampened are. Such relative movements can, for example, to intercept Bumps and shocks arise during the the driving operation of the vehicle may occur.
Bei einer anderen Ausführungsform kann das Zugelement eine Spanneinrichtung aufweisen, 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.at another embodiment the tension element may comprise a tensioning device which is a setting the two exhaust pipes allows each other to driving biasing force. Such a clamping device in particular simplifies the assembly of the tension element and thus the exhaust system.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus der Zeichnung und aus der zugehörigen Figurenbeschreibung anhand der Zeichnung.Further important features and advantages of the invention will become apparent from the Dependent claims, from the drawing and the associated Description of the figures with reference to the drawing.
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 it is understood that the above and the following yet to be explained features not only in the specified combination, but also in other combinations or alone, without to leave the scope of the present invention.
