Abstract
Description
Die Erfindung bezieht sich auf eine mehrteilige Abgasleitung für eine Hubkolbenbrennkraftmaschine, bei der benachbarte Leitungsstücke mittels eines Schiebeelements in axialer Richtung gleitend gegeneinander geführt und mittels eines Dichtelements gegeneinander abgedichtet sind, wobei das Schiebeelement einen mit einem Leitungsstück verbundenen Führungsflansch und einen den Führungsflansch umgreifenden Bund am anderen Leitungsstück aufweist,The The invention relates to a multi-part exhaust pipe for a reciprocating internal combustion engine, at the adjacent line pieces by means of a sliding element in the axial direction sliding against each other guided and are sealed against each other by means of a sealing element, wherein the sliding element connected to a line piece guide flange and one the guide flange has embracing collar on the other line piece,
Eine
derartige Abgasleitung ist aus der
Aufgabe der Erfindung ist es, eine gattungsbildende Abgasleitung dahingehend zu verbessern, dass mit einfachen Mitteln eine gute Ab dichtung zwischen den benachbarten Leitungsstücken gewährleistet ist und dass eine hinreichende Verschiebemöglichkeit besteht.task The invention is a generic exhaust pipe to the effect to improve that with simple means a good seal between the adjacent line pieces guaranteed is and that there is sufficient displacement.
Die Aufgabe der Erfindung wird dadurch gelöst, dass das Dichtelement am Umfang des Führungsflansches oder der Innenfläche des Bundes zumindest eine umlaufende Ausnehmung aufweist, dass in der Ausnehmung ein Dichtring angeordnet ist, der zumindest in einer radialen Richtung vorgespannt ist und dass der Dichtring eine im Querschnitt gesehen C-förmige Ausgestaltung aufweist.The The object of the invention is achieved in that the sealing element on Circumference of the guide flange or the inner surface the federal government has at least one circumferential recess that in the recess is arranged a sealing ring, at least in one Radial direction is biased and that the sealing ring in the Cross-section seen C-shaped Embodiment has.
Bei den umlaufenden Ausnehmungen kann es sich um Eindrehungen handeln, die an verschiedenen Stellen des Führungsflansches oder des Bundes angebracht sind. Die Ausnehmungen können aber auch beim Gießen eingeformt sein, wenn eine hinreichende Oberflächenqualität darstellbar ist. In die Ausnehmung wird ein Dichtring eingesetzt, der zumindest in einer radialen Richtung, vorzugsweise in beiden radialen Richtungen, eine Vorspannung aufweist. Der Dichtring ist dabei in vorteilhafter Weise im Querschnitt gesehen C-förmig ausgestaltet, so dass er aufgrund seiner Formgestaltung in der Lage ist, in beiden radialen Richtungen eine Vorspannung zu erzeugen und eine hohe Dichtheit zu bewirken. Ist die Ausnehmung auf der Fläche des Führungsflansches bzw. des Bundes angebracht, so ist der C-förmige Dichtring vorzugsweise an einer Stelle des Querschnitts durchtrennt, damit er in die Ausnehmung eingesetzt werden kann. Er kann so genau angepasst sein, dass die Stirnflächen gegeneinander stoßen und abdichten, zumal die C-förmige Ausgestaltung auch eine höhere Elastizität in Umfangsrichtung zulässt. Der Dichtring kann aber auch so ausgebildet sein, dass die Enden ineinander gesteckt werden, wobei ein Ende des C-förmigen Querschnitts kleiner ausgebildet ist.at the circumferential recesses may be indentations, at different points of the guide flange or the federal government are attached. The recesses can also be molded during casting be, if a sufficient surface quality can be displayed. In the recess a sealing ring is used which, at least in a radial direction, preferably in both radial directions, a bias voltage. The sealing ring is seen in an advantageous manner in cross section C-shaped designed so that it is able to shape because of its shape, to generate a bias in both radial directions and a to effect high tightness. Is the recess on the surface of the guide flange or the covenant attached, so is the C-shaped Sealing ring preferably cut at one point of the cross section, so that it can be inserted into the recess. He can be so accurate be adapted to the faces collide against each other and caulk, especially the C-shaped Design also a higher elasticity in the circumferential direction. But the sealing ring can also be designed so that the ends nested, with one end of the C-shaped cross-section smaller is trained.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass der umlaufende Öffnungsspalt des C-förmigen Dichtringes in Richtung des benachbarten Leitungsstückes derart ausgerichtet ist, dass er mit Abgasen aus der Abgasleitung befüllbar ist. Da das Abgas unter einem gewissen Druck steht, insbesondere dann, wenn ein Abgasturbolader zur Anwendung kommt, dann erzeugt der Druck des Abgases im C-förmigen Dichtring in vorteilhafter Weise eine radiale Druckbelastung, die zu erhöhter Dichtheit führt.In Another embodiment of the invention is proposed that the circumferential opening gap of the C-shaped Sealing ring in the direction of the adjacent line piece such is aligned so that it can be filled with exhaust gases from the exhaust pipe. Since the exhaust gas is under a certain pressure, especially then, if an exhaust gas turbocharger is used, then the pressure is generated of the exhaust gas in the C-shaped Sealing ring advantageously a radial pressure load, the too high Tightness leads.
Die zuvor beschriebene Wirkung zur Erhöhung des Anpressdruckes im C-förmigen Dichtring kann zum einen zur Anwendung kommen, wenn die Ausnehmung als Nut ausgebildet ist und der Öffnungsspalt mit dem Spalt zwischen Führungsflansch und Bund in Wirkverbindung steht. Dabei ist dann der Spalt zwischen Führungsflansch und Bund von der Nut bis zum Innenraum der Abgasleitung in vorteilhafter Weise größer ausgebildet als der restliche Spalt zwischen dem Führungsflansch und dem Bund.The previously described effect for increasing the contact pressure in C-shaped Sealing ring can be used on the one hand, if the recess is formed as a groove and the opening gap with the gap between the guide flange and Bund is in operative connection. Here then is the gap between guide flange and collar of the groove to the interior of the exhaust pipe in an advantageous Fashioned larger as the remaining gap between the guide flange and the collar.
Die Ausnehmung kann aber auch als Absatz an dem dem Bund zugewandten Ende des Führungsflansches ausgestaltet sein, wobei dann der Öffnungsspalt mit dem Innenraum des Abgases unmittelbar in Wirkverbindung steht. Im letztgenannten Fall kann dann der C-förmige Dichtring auch als geschlossener Ring ausgebildet sein.The Recess can also be used as a paragraph on the collar facing End of the guide flange be configured, in which case the opening gap with the interior the exhaust gas is directly in operative connection. In the latter Case can then be the C-shaped Seal also be designed as a closed ring.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass parallel zur ersten Ausnehmung, insbesondere dann, wenn die erste Ausnehmung als Nut ausgebildet ist, eine weitere Ausnehmung vorgesehen ist. Diese Ausnehmung, die vorzugsweise auch als Nut ausgebildet ist, kann als Drossel wirken, für den Fall, dass Abgase trotzdem den Dichtring passieren.In Another embodiment of the invention is proposed that parallel to the first recess, in particular when the first recess is formed as a groove, a further recess is provided. This recess, which is preferably also designed as a groove, can act as a throttle, for the case that exhaust still passes the sealing ring.
In einer weiteren Ausgestaltung kann aber auch ein weiterer C-förmiger Dichtring nach einem der vorhergehenden Patentansprüche eingebaut sein, so dass eine Doppeldichtung vorliegt.In a further embodiment, but also a further C-shaped sealing ring after a be incorporated in the preceding claims, so that there is a double seal.
Es hat sich herausgestellt, dass eine gute Abdichtung dann gegeben ist, wenn der Umfang des Führungsflansches und die Innenfläche des Bundes in Verbindung mit der Tiefe der Ausnehmung zumindest im Bereich des Dichtringes in ihren Abmessungen so aufeinander abgestimmt sind, dass der C-förmige Dichtring etwa 0,2 – 0,3 mm in seinem Querschnitt verformt wird.It it has turned out that a good seal is then given is when the scope of the guide flange and the inner surface the federal in connection with the depth of the recess at least In the area of the sealing ring in their dimensions so matched are that the C-shaped Sealing ring about 0.2 - 0.3 mm is deformed in its cross section.
Der C-förmige Dichtring kann in seiner Querschnittsform sowohl eine Kreis- als auch eine Ellipsenkontur aufweisen. Vorteilhaft ist auch eine Wandstärke von ca. 0,3 mm, wobei ein warmfestes Material zur Anwendung kommt, so dass die Federspannung auch bei den an der Abgasleitung auftretenden Temperaturen gewährleistet ist.Of the C-shaped Sealing ring can in its cross-sectional shape both a circular as also have an elliptical contour. Also advantageous is a wall thickness of about 0.3 mm, with a heat-resistant material is used, so that the spring tension even at the temperatures occurring at the exhaust pipe guaranteed is.
