Abstract
Description
Die Erfindung betrifft ein Turbolader-Gehäuse eines Abgas-Turboladers eines Verbrennungsmotors.The invention relates to a turbocharger housing Exhaust gas turbocharger of an internal combustion engine.
Ein Gehäuse eines Abgasturboladers,
insbesondere für
ein Kraftfahrzeug, ist in der Regel aus einem metallischen Werkstoff
gefertigt. Eine Gewichtseinsparung ist durch die Verwendung von
keramischen Werkstoffen oder Kohlenstoffverbundwerkstoffen möglich. Turbolader-Gehäuse aus
solchen Werkstoffen sind beispielsweise aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Turbolader-Gehäuse für einen Abgasturbolader eines Verbrennungsmotors anzugeben, welches sich bei geringem Gewicht durch eine besonders rationelle Herstellungsmöglichkeit auszeichnet.The invention is based on the object Turbocharger housing for one Exhaust gas turbocharger to specify an internal combustion engine, which is at low weight due to a particularly efficient manufacturing option distinguished.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Turbolader-Gehäuse eines Abgasturboladers eines Verbrennungsmotors mit den Merkmalen des Anspruchs 1. Das Turbolader-Gehäuse weist ein Verdichtergehäuse auf, welches aus einem Duroplast gefertigt ist. Das Verdichtergehäuse ist dabei mehrteilig ausgebildet mit einer Verdichterrückwand und einem Verdichterfrontteil, welche zwischen sich einen Verdichterinnenraum einschließen. Zumindest im Bereich des Verdichterfrontteils weist die von diesem gebildete Wandung des Verdichterinnenraums eine Schneckenkontur auf. Die mehrteilige Ausbildung des Verdichtergehäuses aus Duroplast-Bauteilen ermöglicht sehr rationelle Fertigungsverfahren, wobei ohne Nachbearbeitung gute Oberflächenqualitäten erzeugbar sind. Durch diese gute Oberflächenqualität der Verdichterrückwand sowie des Verdichterfrontteils ist die innere Reibung der Luft im Verdichterinnenraum herabgesetzt. Die geringe Reibung erhöht zum einen unmittelbar die im Verdichterinnenraum erzielbaren Strömungsgeschwindigkeiten und damit den möglichen Luftdurchsatz durch den Verdichter. Zum anderen bewirkt die geringe Reibung eine entsprechend geringe reibungsbedingte Aufheizung der Luft, wodurch die Aufheizung der Luft im Verdichter reduziert wird und somit die geförderte Luftmasse zusätzlich erhöht wird.According to the invention, this object is achieved by a turbocharger housing an exhaust gas turbocharger of an internal combustion engine with the features of Claim 1. The turbocharger housing has a compressor housing which is made of a thermoset. The compressor housing is formed in several parts with a compressor rear wall and a compressor front part, which has a compressor interior between them lock in. At least in the area of the front part of the compressor points from it formed wall of the compressor interior a screw contour on. The multi-part design of the compressor housing Duroplastic components enabled very rational manufacturing processes, without post-processing good surface qualities can be produced are. Because of this good surface quality of the compressor rear wall as well of the compressor front part is the internal friction of the air inside the compressor reduced. The low friction on the one hand directly increases the Compressor interior achievable flow rates and thus the possible Air flow through the compressor. On the other hand, the low one Friction is a correspondingly low heating due to friction Air, which reduces the heating of the air in the compressor and thus the delivered air mass additionally elevated becomes.
Die Erfindung geht von der Überlegung aus, dass bei einem Abgasturbolader für einen Verbrennungsmotor stark temperaturbeanspruchte Bauteile hauptsächlich im Bereich der Turbine vorhanden sind. Die Werkstoffe der Turbine des Turboladers müssen daher eine entsprechende Temperaturbeständigkeit aufweisen. Dagegen sind die Bauteile des Turboladers in dessen Verdichterteil vergleichsweise gering thermisch beansprucht. Die in diesem Teil des Turboladers, insbesondere des Turbolader-Gehäuses verwendeten Werkstoffe müssen daher nicht notwendigerweise mit den für die Turbine des Turboladers verwendeten Werkstoffen übereinstimmen oder eine ähnliche Temperaturbeständigkeit aufweisen. Aus diesem Grund kann das Gehäuse des Turboladers im Bereich des Verdichters, das so genannte Verdichtergehäuse, aus einem thermisch relativ gering belastbaren, jedoch sehr rationell verarbeitbaren Werkstoff, nämlich einem Duroplast, gefertigt sein. Durch die Teilung des Verdichtergehäuses in eine Verdichterrückwand und ein Verdichterfrontteil ist eine besonders rationelle Herstellung, z.B. im Druckguss- oder Spritzgussverfahren, ermöglicht.The invention is based on the consideration from that strong in an exhaust gas turbocharger for an internal combustion engine Components subject to high temperatures mainly in the area of the turbine available. The materials of the turbine of the turbocharger must therefore have an appropriate temperature resistance. On the other hand are the components of the turbocharger in its compressor part comparatively low thermal stress. The in this part of the turbocharger, especially the turbocharger housing used materials must therefore not necessarily with those for the turbine of the turbocharger used materials match or a similar one Have temperature resistance. For this reason, the housing of the Turbocharger in the area of the compressor, the so-called compressor housing a relatively low thermal load, but very efficient processable material, namely a thermoset. By dividing the compressor housing into a compressor rear wall and a compressor front part is a particularly efficient production, e.g. in die casting or injection molding.
Die Schneckenkontur des Verdichterinnenraums ist zumindest im Wesentlichen im Bereich des Verdichterfrontteils ausgebildet. In fertigungstechnisch vorteilhafter Weise ist das Verdichterfrontteil bevorzugt mehrteilig, mit einer Außenschale und einer Laufschale, ausgebildet. Dabei weist die Laufschale bevorzugt eine, bezogen auf die Rotationsachse des Turbinenlaufrads, zumindest im Wesentlichen rotationssymmetrische Laufradgegenfläche auf.The screw contour of the compressor interior is at least essentially in the area of the compressor front part educated. This is advantageous in terms of production technology Compressor front part preferably in several parts, with an outer shell and a running shell. The barrel shell preferably has one, based on the axis of rotation of the turbine impeller, at least essentially rotationally symmetrical impeller counter surface.
Die Verdichterrückwand kann in fertigungstechnisch besonders einfacher Weise eine im Wesentlichen ebene Begrenzung des Verdichterinnenraums bilden. Eine strömungstechnische Verbesserung im Verdichterinnenraum ist jedoch vorzugsweise dadurch erreicht, dass die Schneckenkontur innerhalb des Verdichterinnenraums teilweise auch durch die Verdichterrückwand gebildet ist.The compressor rear wall can be used in production engineering an essentially flat boundary in a particularly simple manner of the compressor interior. A fluidic improvement in the compressor interior, however, is preferably achieved by that the screw contour partially inside the compressor interior also through the rear wall of the compressor is formed.
Ein Öffnen des aus der Verdichterrückwand und dem Verdichterfrontteil zusammengesetzten Turbolader-Gehäuses ist in der Regel nicht vorgesehen. Das Verdichterfrontteil ist daher mit der Verdichterrückwand vorzugsweise nicht lösbar, beispielsweise durch eine Schnappverbindung und/oder eine Klebeverbindung gasdicht verbunden.Opening the from the back of the compressor and the compressor front part is assembled turbocharger housing usually not provided. The compressor front part is therefore with the compressor rear wall preferably not solvable, for example by a snap connection and / or an adhesive connection connected gastight.
