Description

Die Erfindung bezieht sich auf eine Dichtvorrichtung zur Anordnung zwischen im Obergriff des Patentanspruches 1 beschriebenen Bauteilen.The invention relates to a sealing device for Arrangement between in the upper grip of claim 1 described components.

Eine einwandfrei abgedichtete Verbindung zwischen einem aus Eisengußwerkstoff gebildeten Auspuffkrümmer und einem aus Leichtmetall gefertigten Zylinderkopf einer mehrzy­ lindrigen Reihen-Brennkraftmaschine ist bei Verwendung von bekannten, durch den Aufbau kostengünstigen Flansch­ dichtungen über die gesamte Einsatzzeit kaum möglich. Diese aus einem beidseitig blechkaschierten, ggf. ver­ stärkten Weichstoff gebildeten Flanschdichtungen sind durch die für eine Dichtwirkung erforderliche Pressung einerseits und durch hierzu quergerichtete, aus tempera­ turabhängigen Relativbewegungen des Auspuffkrümmers resultierende Kräfte andererseits mechanisch hoch bela­ stet. Der diesen Belastungen ausgesetzte Weichstoff wird dadurch zerrüttet mit der nachteiligen Folge von zu Un­ dichtigkeiten führenden Setzvorgängen. Weiter können an den vorgenannten Bauteilen durch thermische Belastung bedingte Formänderungen auftreten, die eine ungleich­ mäßige Pressung des Weichstoffes der Flanschdichtungen bzw. der Dichtvorrichtungen bewirken und ebenfa1ls zu Undichtigkeiten führen.A perfectly sealed connection between one Exhaust manifold formed from cast iron material and one cylinder head made of light metal of a multi-cylinder bogus in-line engine is in use of known, by the inexpensive construction flange Seals hardly possible over the entire period of use. This from a sheet metal laminated on both sides, if necessary ver strong soft material are formed flange seals due to the pressure required for a sealing effect on the one hand and by means of tempera which is transverse to this relative movements of the exhaust manifold resulting forces on the other hand mechanically high continuous The soft material exposed to these stresses becomes thereby disrupted with the adverse consequence of too un leak-proof setting processes. Can continue to the aforementioned components due to thermal stress conditional shape changes occur that are unequal moderate compression of the soft material of the flange seals or the sealing devices and also Cause leaks.

Der Erfindung liegt die Aufgabe zugrunde, eine Dichtvor­ richtung für die eingangsbeschriebene Anordnung so zu gestalten, daß die zueinander quergerichteten Belastungen von Pressungen und Querkräften nicht wechselseitig wirk­ sam sind.The invention has for its object a Dichtvor direction for the arrangement described above  shape that the transverse loads of pressures and transverse forces are not mutually effective are sam.

Gelöst wird diese Aufgabe mit den im Kennzeichen des Patentanspruches 1 angegebenen Merkmalen.This object is achieved with the features specified in the characterizing part of patent claim 1 .

Bei der erfindungsgemäßen Dichtvorrichtung übernimmt eine zwischen den Bauteilen gepreßt angeordnete, eine Durch­ brechung aufweisende Metallplatte die Querkräfte aus den temperaturbedingten Relativbewegungen der Bauteile, wäh­ rend ein in der Durchbrechung der Metallplatte im unge­ preßten Zustand deren Stärke übersteigender Dichtring im wesentlichen lediglich der Pressung zur Bewirkung einer einwandfreien Abdichtung ausgesetzt ist. Der somit in vorteilhafter Weise von Querkräften freie Dichtring kann damit hinsichtlich des Weichstoffes bzw. der Dicht­ materialien und seiner für die Pressung relevanten Stärke der jeweiligen Anordnung entsprechend optimal gestaltet werden. Insbesondere lassen sich empfindlichere Weich­ stoffarten mit gutem Pressungsausgleich verwenden, wie z. B. Glimmer. Die durch die Wahl der Stärke des Dicht­ ringes und eines Weichstoffes erreichte gleichmäßige Pressung eliminiert zusätz1ich aus Formänderungen der Bauteile mögliche Undichtigkeiten.In the sealing device according to the invention, one takes over arranged between the components, a through refractive metal plate the transverse forces from the temperature-related relative movements of the components, wuh rend in the opening in the metal plate in the pressed condition of their sealing ring in excess of strength essentially only the pressure to effect one proper sealing is exposed. The thus in can advantageously free of transverse forces sealing ring thus with regard to the soft material or the density materials and its strength relevant for pressing optimally designed according to the respective arrangement will. In particular, more sensitive soft can be used use types of fabric with good pressure compensation, such as e.g. B. mica. By choosing the strength of the seal ring and a soft material reached uniform Pressing additionally eliminates changes in shape of the Components possible leaks.

Um ferner eine aus der Relativbewegung der Bauteile resultierende, für den Dichtring der erfindungsgemäßen Dichtvorrichtung ungünstige Verschiebung zu vermeiden, kann die Metallplatte an einem der Bauteile mit der geringeren temperaturabhängigen Längenänderung über eine profilierte Auflagefläche fixiert sein. Weiter können den Flanschkonturen eines der Bauteile entsprechend gestal­ tete Metallplatten mit einander durch Stege zu einem einzigen Teil verbunden sein, das ggf. gesondert befestigbar ausgebildet ist.
In order to further avoid a displacement resulting from the relative movement of the components, which is unfavorable for the sealing ring of the sealing device according to the invention, the metal plate can be fixed on one of the components with the lower temperature-dependent change in length via a profiled contact surface. Furthermore, the flange contours of one of the components can be connected to each other by webs to form a single part, which can be separately fastened, if necessary.

Zur sicheren Abdichtung zwischen gegeneinander verspannten, im Heißbetrieb gegeneinander relativ ver­ schiebebeweglichen Bauteilen, insbesondere bei einer nicht dargestellten Brennkraftmaschine zwischen einem Zylinderkopf aus Leichtmetall und einem Abgaskrümmer aus Eisengußwerkstoff, ist eine Dichtvorrichtung 1 vorgesehen. Diese kennzeichnet sich durch eine ein- oder mehrlagige Metallplatte 2 mit einer Durchbrechung 3 und einem in der Durchbrechung 3 über einen Ringspalt 4 beab­ standet angeordneten Dichtring 5. Der Dichtring 5 ist aus einem in einer im Querschnitt U-förmigen metallischen Einfassung 6 angeordneten Weichstoff 7 gebildet. Zur Fixierung des Dichtringes 5 an der Metallplatte 2 ist ein Schenkel 8 der Einfassung 6 über den Ringspalt 4 hinaus verlängert derart, daß er eine Seite der Metallplatte 2 zur Gänze bedeckt. Der verlängerte Schenkel 8 ist mit der Metallplatte 2 fest verbunden, z. B. durch Schweißen. Weiter ist der Dichtring 5 bezüglich der Dichtpressung maßlich derart abgestimmt, daß er im ungepreßten Zustand eine die Stärke der mehrlagigen Metallplatte 2′ um das Maß "x" übersteigende Abmessung aufweist.A sealing device 1 is provided for secure sealing between mutually clamped components which are relatively displaceable in hot operation relative to one another, particularly in an internal combustion engine (not shown) between a cylinder head made of light metal and an exhaust manifold made of cast iron material. This is characterized by a single or multi-layer metal plate 2 with an opening 3 and a spaced in the opening 3 via an annular gap 4 spaced sealing ring 5th The sealing ring 5 is formed from a soft material 7 arranged in a cross-sectionally metallic enclosure 6 . To fix the sealing ring 5 on the metal plate 2 , a leg 8 of the skirt 6 is extended beyond the annular gap 4 in such a way that it completely covers one side of the metal plate 2 . The elongated leg 8 is fixed to the metal plate 2 , for. B. by welding. Furthermore, the sealing ring 5 is dimensionally matched with respect to the sealing pressure in such a way that in the unpressed state it has a dimension exceeding the thickness of the multi-layer metal plate 2 'by the dimension "x".

Um eine aus der Relativbewegung der nicht gezeigten Bau­ teile resultierende Verschiebung der Dichtvorrichtung 1 zu vermeiden, kann die Metallplatte 2′ in einer bedeckungsfreien Auflagefläche 9 profiliert sein zur formflüssigen Verbindung mit dem zugeordneten Bauteil. In order to avoid a displacement of the sealing device 1 resulting from the relative movement of the construction parts, not shown, the metal plate 2 'can be profiled in a cover-free support surface 9 for a fluid connection with the associated component.

Wie aus Fig. 1 weiter hervorgeht, können die Metallplatten 2 entsprechend zugeordneten Flanschkonturen eines der Bauteile, z. B. des Auspuffkrümmers, gestaltet sein, wobei mehrere derartige Metallplatten 2 über Ver­ bindungstege 10; 11 ein einziges Teil 12 bilden. Diese kann weiter mittels eines durchbrochenen Auges 13 am Verbindungsteg 11 an einem der Bauteile gesondert befe­ stigt werden.As can further be seen from FIG. 1, the metal plates 2 can be correspondingly assigned flange contours of one of the components, for. B. the exhaust manifold, be designed, several such metal plates 2 via Ver connecting webs 10 ; 11 form a single part 12 . This can be separately BEFE Stigt by means of a broken eye 13 on the connecting web 11 on one of the components.
