Abstract
Description
Die vorliegende Erfindung betrifft eine Abgasanlage für ein verbrennungsmotorisch angetriebenes Kraftfahrzeug, umfassend mehrere bezüglich einander justierbare Komponenten, welche im Bereich einer Rohrverbindung lösbar miteinander verbunden sind, wobei die beiden miteinander verbundenen Rohrabschnitte mittels eines an einer sphärischen Dichtfläche des einen, ersten Rohrabschnitts anliegenden Dichtungsrings gegeneinander abgedichtet sind.The present invention relates to an exhaust system for a motor vehicle powered by an internal combustion engine, comprising a plurality of components which can be adjusted with respect to one another, which is detachable in the area of a pipe connection are connected with each other, the two with each other connected pipe sections by means of a spherical sealing surface of one, first pipe section adjacent sealing ring sealed against each other are.
Abgasanlagen der vorstehend angegebenen Art sind in verschiedenen Ausführungen bekannt. Offenbart werden sie beispielsweise in der DE 19608870 C1, der DE 19964223 A1, der FR 2577986 A1, der DE 3512751 C2 und der DE 19508979 C2.Exhaust systems of the type specified above are in various versions known. Be revealed for example in DE 19608870 C1, DE 19964223 A1, FR 2577986 A1, DE 3512751 C2 and of DE 19508979 C2.
Ein wesentliches Konstruktionsmerkmal der bekannten gattungsgemäßen Abgasanlagen ist dabei, daß der erste Rohrabschnitt eine tulpenartige Erweiterung aufweist, deren Innenfläche als sphärische Dichtfläche ausgeführt ist, wobei die Außenfläche des Dichtungsrings korrespondierend zu der Dichtfläche des ersten Rohrabschnitts sphärisch ausgeführt ist und der Dichtungsring großflächig an der Dichtfläche des ersten Rohrabschnitts anliegt. Bedingt hierdurch sind die Dichtungsringe, die nicht nur der Abdichtung der beiden Rohrabschnitte gegeneinander, sondern auch der mechanischen Abstützung der Rohrabschnitte aneinander dienen, vergleichsweise großformatig, was bei Verwendung eines im Hinblick auf die spezifischen mechanischen und thermischen Anforderungen optimierten Materials zu nicht unerheblichen Kosten für den jeweiligen Dichtungsring führt. Dies wirkt sich nicht nur bei der Herstellung der Abgasanlage nachteilig aus, sondern auch bei deren Wartung, nämlich wenn eine Erneuerung des Dichtungsrings erforderlich ist. Zudem besteht beim Einsatz gattungsgemäßer Abgasanlagen bei spezifischen Anwendungsfällen, beispielsweise im Falle von Torsionsschwingungen zwischen den beiden miteinander verbundenen Komponenten der Abgasanlage, die Gefahr einer Beschädigung des Dichtungsrings.An essential design feature of the known Generic exhaust systems is that the first Pipe section has a tulip-like extension, the inner surface of which is designed as a spherical sealing surface is, the outer surface of the sealing ring corresponding to the sealing surface of the first pipe section is spherical and the sealing ring is large abuts the sealing surface of the first pipe section. This means that the sealing rings are not only the sealing of the two pipe sections against each other, but also the mechanical support the pipe sections serve each other, comparatively large format what when using one with regard to the specific mechanical and thermal requirements optimized material for not insignificant Costs for the respective sealing ring leads. This not only affects the manufacture of the exhaust system disadvantageous, but also in their maintenance, namely when a replacement of the sealing ring is required. There is also a generic use Exhaust systems for specific applications, for example in the case of torsional vibrations between the two interconnected components the exhaust system, the risk of damage to the Sealing ring.
Bekannt ist darüber hinaus in der Abgastechnik die Verbindung zweier Komponenten über eine keine gesonderte Dichtung aufweisende Kugelzonenverbindung. Auch in diesem Falle ist eine Justierung der beiden miteinander verbundenen Komponenten der betreffenden Abgasanlage zueinander möglich. Indessen sind solchermaßen ausgeführte Abgasanlagen ungeeignet, wenn sie im Bereich der betreffenden Kugelzonenverbindung wiederholt zerlegt und hernach wieder zusammengefügt werden sollen, ohne daß sich sicherstellen läßt, daß die beiden Komponenten stets in exakt derselben Position zueinander montiert werden.The connection is also known in exhaust technology two components over one no separate Spherical zone connection with seal. Also in this Trap is an adjustment of the two together connected components of the exhaust system concerned to each other possible. Meanwhile, are executed in this way Exhaust systems unsuitable if they are in the area of repeatedly disassembled ball zone connection concerned and then to be put together again without that it can be ensured that the two components always mounted in exactly the same position to each other become.
Der vorliegenden Erfindung liegt demgemäß die Aufgabe zugrunde, eine Abgasanlage der eingangs angegebenen Art bereitzustellen, die bei vergleichsweise geringen Herstellungs- und Wartungskosten zuverlässig und dauerhaft den in der Praxis bestehenden Anforderungen, zu denen insbesondere auch die ständig steigenden Anforderungen an die Dichtheit zählen, genügt, wobei insbesondere ein Zerlegen und anschließendes Wiederzusammenfügen der Abgasanlage im Bereich der Kugelzonenverbindung ohne nachteilige Auswirkungen möglich sein soll. The object of the present invention is accordingly based on an exhaust system of the type specified to provide the comparatively low manufacturing and maintenance costs reliably and permanently the existing requirements for which especially the ever increasing demands counting on the tightness is sufficient, especially one Disassemble and then reassemble the Exhaust system in the area of the ball zone connection without adverse effects should be possible.
Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung dadurch, daß der zweite Rohrabschnitt beiderseits des Dichtungsrings zur sphärischen Dichtfläche des ersten Rohrabschnitts korrespondierende sphärische Anlageflächen aufweist, wobei die sphärischen Anlageflächen des zweiten Rohrabschnitts beiderseits des Dichtungsrings flächig an der sphärischen Dichtfläche des ersten Rohrabschnitts anliegen. Die erfindungsgemäße Abgasanlage zeichnet sich somit insbesondere dadurch aus, daß die mechanischen Belastungen zwischen den beiden im Bereich der Kugelzonenverbindung miteinander verbundenen Komponenten der Abgasanlage über die beiderseits des Dichtungsrings an der sphärischen Dichtfläche des ersten Rohrabschnitts anliegenden sphärischen Anlageflächen des zweiten Rohrabschnitts übertragen werden. Hieraus ergibt sich eine weitestgehende mechanische Entlastung des Dichtungsrings. Dieser kann, was seine Dimensionierung und Materialauswahl angeht, somit spezifisch auf seine Dichtungsfunktion hin optimiert werden. Insbesondere lassen sich im Rahmen der vorliegenden Erfindung Dichtungsringe verwenden, welche erheblich kostengünstiger sind als die für die eingangs angegebenen gattungsgemäßen Abgasanlagen erforderlichen Dichtungsringe. Durch die mechanische Entlastung des Dichtungsrings ist zudem dessen Verschleiß gemindert; dies führt zu einer besonders dauerhaft dichten Verbindung der beiden Komponenten im Bereich der Kugelzonenverbindung. Dabei ist auch ein Zerlegen der Abgasanlage im Bereich der Kugelzonenverbindung mit anschließendem Wiederzusammenbau selbst dann ohne Beeinträchtigung der Funktion möglich, wenn die Lage der beiden miteinander zu verbinden Komponenten bei dem Wiederzusammenbau der Abgasanlage von der ursprünglichen Lage abweicht. In der Regel ist dabei noch nicht einmal ein Austausch des Dichtungsrings erforderlich, wobei der Dichtungsring, sollte dies doch erforderlich sein, zu minimalen Kosten ausgetauscht werden kann.This task is solved according to the present Invention in that the second pipe section on both sides of the sealing ring to the spherical sealing surface corresponding to the first pipe section has spherical contact surfaces, the spherical Contact surfaces of the second pipe section on both sides of the sealing ring flat on the spherical Apply sealing surface of the first pipe section. The Exhaust system according to the invention is thus particularly distinguished characterized in that the mechanical loads between the two in the area of the spherical zone connection interconnected components of the exhaust system on both sides of the sealing ring on the spherical Bearing surface of the first pipe section spherical contact surfaces of the second pipe section be transmitted. This results in a largely mechanical relief of the sealing ring. This can what its sizing and choice of materials concerned, specifically on its sealing function be optimized. In particular, within the framework of the present invention use sealing rings which are significantly cheaper than those for the generic exhaust systems specified at the outset required sealing rings. By mechanical Relieving the sealing ring is also its wear reduced; this leads to a particularly permanent tight connection of the two components in the Spherical zone connection area. There is also a Disassembly of the exhaust system in the area of the spherical zone connection with subsequent reassembly itself then possible without impairing the function if the location of the two components to be interconnected when reassembling the exhaust system from the original location deviates. Usually there is it is not even necessary to replace the sealing ring, with the sealing ring, should it be be exchanged at minimal cost can be.
Mit besonderen Vorteil läßt sich die vorliegende Erfindung im Falle der Ausführung der Abgasanlage als eine solche für ein Motorrad anwenden. Denn bei Motorrädern muß häufig zum Wechsel des Hinterrades der Schalldämpfer abgenommen werden, was gemäß den vorstehenden Ausführungen im Falle der Ausführung der Abgasanlage nach der vorliegenden Erfindung problemlos und ohne Beeinträchtigung der Funktion nach der anschließenden erneuten Montage des Schalldämpfers möglich ist.The present invention can be used with particular advantage in the case of execution of the exhaust system as one use those for a motorcycle. Because with motorcycles often needs to change the rear wheel of the muffler be taken off what according to the above in case of execution of the exhaust system after of the present invention easily and without impairment the function after the subsequent renewed Installation of the silencer is possible.
In gleicher Weise vorteilhaft ist der Einsatz der vorliegenden Erfindung bei Abgasanlagen für Kraftwagen, wobei hier insbesondere die hervorragenden Eigenschaften hinsichtlich der Dichtigkeit zum Tragen kommen.The use of the present is equally advantageous Invention in exhaust systems for motor vehicles, here in particular the excellent properties in terms of tightness.
Eine erste bevorzugte Weiterbildung der erfindungsgemäßen Abgasanlage zeichnet sich dadurch aus, daß der erste Rohrabschnitt eine tulpenartige Erweiterung aufweist, deren Innenfläche als sphärische Dichtfläche ausgeführt ist. Besonders bevorzugt weist dabei der zweite Rohrabschnitt eine Kugelzone auf, auf deren Außenfläche beiderseits einer den Dichtungsring aufnehmenden Sicke die sphärischen Anlageflächen ausgebildet sind. Besonderer Vorteil dieser Ausführungsform ist die Möglichkeit einer vergleichsweise glatten Außenfläche der Abgasanlage im Bereich der Kugelzonenverbindung, was namentlich bei freiliegenden Abgasanlagen von Motorrädern unter ästhetischen Gesichtspunkten günstig ist. Zudem sind in diesem Falle an die weiteren der Verbindung der beiden Komponenten dienenden Bauteile wie Schellen und dergleichen keine besonderen Anforderungen zu stellen. Insbesondere lassen sich Schellen einsetzen, deren Innenfläche zu der sphärischen Außenfläche der Tulpe korrespondiert, so daß Schelle und Tulpe ohne weiteres in verschiedenen Stellungen vergleichsweise großflächig aneinander anliegen können.A first preferred development of the invention Exhaust system is characterized in that the first Pipe section of a tulip-like extension has, the inner surface as a spherical sealing surface is executed. The second pipe section on a spherical zone, on the outer surface on both sides one receiving the sealing ring Bead formed the spherical contact surfaces are. A particular advantage of this embodiment is that Possibility of a comparatively smooth outer surface the exhaust system in the area of the spherical zone connection, which is particularly the case with exposed exhaust systems of motorcycles favorable from an aesthetic point of view is. In this case, the others are also the Connection of the two components serving components like clamps and the like, no special requirements to deliver. In particular, clamps can be used insert, the inner surface of which to the spherical outer surface the tulip corresponds, so that clamp and Tulip easily compared in different positions can lie against each other over a large area.
Gemäß einer anderen bevorzugten Weiterbildung der Erfindung ist vorgesehen, daß der erste Rohrabschnitt eine Kugelzone aufweist, deren Außenfläche als sphärische Dichtfläche ausgeführt ist. Dabei weist der zweite Rohrabschnitt besonders bevorzugt eine tulpenartige Erweiterung auf, auf deren Innenfläche beiderseits einer den Dichtungsring aufnehmenden Sicke die sphärischen Anlageflächen ausgebildet sind. Bei dieser Ausführungsform erweist sich als besonders vorteilhaft, daß die Innenfläche der Abgasanlage im Bereich der Kugelzonenverbindung besonders glatt ausgeführt werden kann, was sich auf die Strömungsverhältnisse günstig auswirkt.According to another preferred development of the invention it is provided that the first pipe section has a spherical zone, the outer surface of which is spherical Sealing surface is executed. The second points Pipe section particularly preferably a tulip-like Extension to, on the inner surface on either side of one the spherical bead accommodating the sealing ring Contact surfaces are formed. At this Embodiment proves to be particularly advantageous that the inner surface of the exhaust system in the area of the spherical zone connection run particularly smoothly can what is favorable on the flow conditions effect.
Lediglich der Vollständigkeit halber ist darauf hinzuweisen, daß die sphärischen Anlageflächen keineswegs zwingend umlaufend vollständig geschlossen sein müssen. Vielmehr können die sphärischen Anlageflächen bei besonders gelagerten Verhältnissen auch unterteilt sein, so daß sich die Kraftübertragung zwischen den miteinander verbundenen Komponenten auf mehrere einzelne Zonen verteilt. Wichtig ist dabei allerdings, daß entsprechend dem Wesen der vorliegenden Erfindung beiderseits des Dichtungsrings eine mechanische Anlage der beiden Rohrabschnitte aneinander über die mit der sphärischen Dichtfläche des ersten Rohrabschnitts in Kontakt stehenden Anlageflächen des zweiten Rohrabschnitts besteht.It should only be pointed out for the sake of completeness that the spherical contact surfaces by no means must be completely closed all around. Rather, the spherical contact surfaces can be particularly stored conditions can also be divided, so that the power transmission between the one another connected components to several individual zones distributed. It is important, however, that accordingly the essence of the present invention on both sides the sealing ring is a mechanical system of the two Pipe sections to each other over the spherical Sealing surface of the first pipe section in contact Contact surfaces of the second pipe section.
