Abstract
Description
Die vorliegende Erfindung betrifft ein Gehäuse für einen Abgasturbolader einer Brennkraftmaschine, insbesondere eines Kraftfahrzeugs. Die Erfindung betrifft außerdem einen mit einem derartigen Gehäuse ausgestatteten Abgasturbolader.The The present invention relates to a housing for an exhaust gas turbocharger of an internal combustion engine, in particular a Motor vehicle. The invention also relates to a equipped exhaust gas turbocharger equipped with such a housing.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Gehäuse der eingangs genannten Art beziehungsweise für einen Abgasturbolader eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie vergleichsweise preiswert herstellbar ist und relativ hohe Betriebstemperaturen ermöglicht.The The present invention addresses the problem of for a housing of the type mentioned or for an exhaust gas turbocharger an improved embodiment particular distinguished by the fact that they are comparatively is inexpensive to produce and relatively high operating temperatures allows.
Dieses Problem wir erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungen sind Gegenstand der abhängigen Ansprüche.This Problem according to the invention by the objects of the independent claims. advantageous Embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, einen Keramikeinsatz mit einer strömungsführenden Innenkontur zu verwenden, der in einer tragenden Schale aus Stahlblech angeordnet ist. Auf diese Weise kann zumindest ein Abschnitt des Gehäuses des Turboladers durch den vorgeschlagenen Stahl-Keramik-Werkstoffverbund realisiert werden. Die als Stützgerüst oder Kapselung dienende Stahlblechschale ist vergleichsweise preiswert herstellbar. Ebenso las sen sich Keramikeinsätze vergleichsweise preiswert herstellen. Keramische Materialien zeichnen sich durch extrem hohe Temperaturbeständigkeit aus. Des Weiteren kann die strömungsführende Innenkontur des Keramikeinsatzes extrem glatt und somit reibungsarm ausgeführt werden. Ferner führt die glatte Oberfläche der keramischen Innenkontur dazu, dass die Gefahr einer unerwünschten Partikelanhaftung und Anlagerung reduziert werden kann. Des Weiteren hat sich gezeigt, dass der hier gewählte Werkstoffverbund zu einer verbesserten Akustik des Abgasturboladers führt.The The invention is based on the general idea of a ceramic insert to use with a flow-guiding inner contour, which is arranged in a supporting shell made of sheet steel. On this way, at least a portion of the housing of the Turbocharger through the proposed steel-ceramic composite material will be realized. The as a scaffold or encapsulation Serving steel sheet is comparatively inexpensive to produce. Likewise, ceramic inserts are comparatively inexpensive produce. Ceramic materials are characterized by extremely high Temperature resistance. Furthermore, the flow-leading Inner contour of the ceramic insert extremely smooth and thus low-friction be executed. Furthermore, the smooth surface leads the ceramic inner contour that the risk of undesirable Particle adhesion and attachment can be reduced. Furthermore has shown that the material composite chosen here leads to improved acoustics of the exhaust gas turbocharger.
Besonders vorteilhaft ist eine Ausführungsform, bei welcher zwischen der Schale und dem Einsatz ein Lagermaterial angeordnet ist, das den Einsatz in der Schale in Position hält. Zum einen kann durch das Lagermaterial eine direkte Kontaktierung zwischen Keramikeinsatz und Stahlblechschale vermieden werden. Dies reduziert die Gefahr einer Beschädigung des Keramikeinsatzes. Zum anderen dämpft das Lagermaterial Schwingungen, was Vibrationen und Geräuschbildung reduziert. Des Weiteren nimmt das Lagermaterial Maßänderungen auf, die aufgrund unterschiedlicher thermischer Wärmedehnungskoeffizenten von Keramik und Stahl auftreten.Especially advantageous is an embodiment in which between the shell and the insert a bearing material is arranged, the holding the insert in place in the shell. For one thing, through the bearing material a direct contact between ceramic insert and sheet steel shell are avoided. This reduces the danger Damage to the ceramic insert. On the other hand dampens the bearing material vibrations, causing vibration and noise reduced. Furthermore, the stock material changes dimensions due to different thermal expansion coefficients of ceramics and steel occur.
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 Subclaims, from the drawing and from 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 each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
