Abstract
Description
Die Erfindung betrifft ein Turbinengehäuse eines Abgasturboladers eines verbrennungsmotorisch angetriebenen Kraftfahrzeuges, wobei das Turbinengehäuse zumindest zwei miteinander in einem Verbindungsbereich verbundene, aus Blech gefertigte Gehäusebauteile umfasst.The The invention relates to a turbine housing of an exhaust gas turbocharger an internal combustion engine driven motor vehicle, wherein the turbine housing at least two together in a connecting region connected, made of sheet metal housing components comprises.

Bisher ist das Fügen von zwei oder mehreren Blechteilen zu einem Turbinengehäuse eines Abgasturboladers problembehaftet. Bisher wird bei Blechbauteilen üblicherweise auf eine Schweißverbindung zurückgegriffen, die jedoch die Nachteile eines Schweißverzuges, aufgrund partieller Erwärmung, Schweißspritzer, Schweißverunreinigungen und eine begrenzte Zugänglichkeit für die benötigte Schweißausrüstung aufweist. Ferner stehen nur geringere Verbindungsquerschnitte im Verhältnis zu anderen Fügeverfahren, bei gleichzeitig längerer Prozesszeit während des Verbindens, zur Verfügung.So far is the joining of two or more sheet metal parts to one Turbine housing of an exhaust gas turbocharger problematic. So far, sheet metal components are usually used on a welded joint, However, the disadvantages of a welding delay, due partial heating, spatter, sweat contamination and limited accessibility for the needed Having welding equipment. Further only smaller connection cross sections in relation to other joining methods, at the same time longer process time during connecting, available.
Es ist die Aufgabe der vorliegenden Erfindung hier Abhilfe zu leisten.It the object of the present invention is to remedy this situation.
Eine erfindungsgemäße Vorrichtung bildet ein gattungsgemäßes Turbinengehäuse dadurch weiter, dass die Gehäusebauteile im Verbindungsbereich kraft- und/oder formschlüssig miteinander verbunden sind.A Device according to the invention forms a generic Turbine housing thereby further that the housing components in the connection area non-positively and / or positively with each other are connected.
Auf diese Weise wird bei kürzerer Fertigungszeit eine längere Lebensdauer aufgrund des Ausbleibens von thermischen Spannungen erreicht. Auch ist die sonst so problematische Schweißverunreinigung nicht mehr auftretend. Auch Schweißspritzer treten nicht mehr auf, so dass eine Gefährdung der Montagepersonen verhindert wird. Auch die Zugänglichkeit von Werkzeugen zu dem Verbindungsbereich wird verbessert.On This way, with shorter production time, a longer Service life due to the absence of thermal stresses reached. Also, the otherwise problematic sweat pollution no longer occurring. Even spatters do not occur more, so that a danger to the assembly persons prevented becomes. Also the accessibility of tools to the connection area will be improved.
Vorteilhafte Ausführungsformen werden ferner in Unteransprüchen beansprucht und nachfolgend näher erläutert.advantageous Embodiments are further sub-claims claimed and explained in more detail below.
So ist es von Vorteil, wenn zusätzlich oder alternativ zu der kraft- und/oder formschlüssigen Verbindung eine Klebe- oder Lötverbindung zwischen den Gehäuseblechteilen in dem Verbindungsbereich realisiert ist. Der große Vorteil von Klebeverbindungen ist die mittlerweile durch die chemische Industrie zur Verfügung gestellte Vielfalt an Klebemitteln, die ein anwendungsspezifisches Verwenden ermöglicht. Im Gegensatz zu stoffschlüssigen Verbindungsformen im Sinne von Schweißverbindungen, wird bei Lötverbindungen nicht so viel Energie benötigt, was zu einem kostengünstigeren Herstellungsverfahren führt.So it is advantageous if, in addition or as an alternative to the non-positive and / or positive connection an adhesive or solder connection between the Gehäuseblechteilen is realized in the connection area. the big advantage Of adhesive bonds is now used by the chemical industry Provided variety of adhesives, which is an application-specific Use allows. Unlike cohesive Connection forms in the sense of welded joints, is not so much energy needed in solder joints resulting in a less expensive manufacturing process.
Es ist ferner von Vorteil, wenn im Verbindungsbereich eine Durchsetzfügeverbindung realisiert ist, da dann die Vorteile eines Clinchens erreicht werden. Sowohl Matrizen mit beweglichen Matrizensegmenten, als auch Matrizen mit starren Matrizensegmenten sind hierbei verwendbar und bieten höhere statische Festigkeiten der verbundenen Gehäusebauteile nach deren Fertigstellung. Auch ist kein Vorlochvorgang notwendig. Die Dauerfestigkeit ist aufgrund von nicht mehr vorhandenen Kerbwirkungen und fehlenden Wärmeeinflusszonen höher als bei bisher üblichen Punktschweißverbindungen. Auch bei unterschiedlichen Blechstärken bietet das Durchsetzfügen große Vorteile, um die statischen Festigkeiten, wie sie benötigt werden, zu gewährleisten.It is also advantageous if in the connection area a clinching connection is realized, since then the advantages of a clinch can be achieved. Both matrices with movable die segments, as well as dies with rigid die segments are hereby usable and provide higher static strength of the connected housing components after completion. Also no Vorlochvorgang is necessary. The fatigue strength is due to no longer existing notch effects and missing heat-affected zones higher than usual Spot welds. Even with different sheet thicknesses Penetration offers great benefits to the user to ensure static strength as needed.
In einem weiteren vorteilhaften Ausführungsbeispiel ist im Verbindungsbereich eine Press-, Falz- oder Clips-Verbindung realisiert. Auch in einem solchen Fall wird eine langlebigere Turbinengehäuseausgestaltung erreicht.In a further advantageous embodiment is in Connection area realized a press, seam or clip connection. Even in such a case, a more durable turbine housing design reached.
