Die vorliegende Erfindung betrifft eine Ladeeinrichtung, insbesondere einen Abgasturbolader für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a charging device, in particular an exhaust gas turbocharger for a motor vehicle according to the Preamble of claim 1.
Gattungsgemäße Ladeeinrichtungen sind hinlänglich bekannt und dienen der Leistungssteigerung von Kolbenmotoren, indem sie einen Luftmengen- und Kraftstoffdurchsatz pro Arbeitstakt erhöhen.generic Charging devices are well known and serve the Increase performance of piston engines by providing an air flow and increase fuel flow per stroke.

Ein großer Nachteil bei sich derzeit am Markt befindlichen Ladeeinrichtungen besteht darin, dass diese einem Abgas relativ viel Wärme entziehen und dadurch ein Katalysator in einem Abgasstrang, insbesondere während einer Startphase des Verbrennungsmotors, nur gering aufgeheizt wird und so seine volle Reinigungsleistung erst mit starker zeitlicher Verzögerung erreicht.One big disadvantage at present on the market Charging devices is that this relative to an exhaust gas extract a lot of heat and thereby a catalyst in one Exhaust line, especially during a launch phase of Internal combustion engine, only slightly heated and so its full Cleaning performance only after a considerable time delay reached.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Ladeeinrichtung der gattungsgemäßen Art, eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, welche sich einerseits insbesondere durch einen geringen abgasseitigen Wärmeentzug und andererseits durch ein geringes Gewicht auszeichnet.The The present invention addresses the problem of for a charging device of the generic type Art, an improved or at least another embodiment indicate, on the one hand, in particular by a low exhaust gas side Heat extraction and on the other hand by a low weight distinguished.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim 1 solved. advantageous Embodiments are the subject of the dependent Claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, ein Turbinengehäuse einer Ladeeinrichtung aus einer einteiligen und als Gussteil ausgebildeten Turbinenkartusche und einem damit verbundenen Spiralgehäuse auszubilden. Die Turbinenkartusche bildet dabei ein Traggerüst für das gesamte Turbinengehäuse, wobei das vorzugsweise aus einer Innenschale und einer Außenschale aufgebaute Spiralgehäuse zwischen seiner Innen- und seiner Außenschale einen definierten Zwischenraum aufweist. Im Bereich eines Anschlusses an ein Lagegehäuse als auch im Bereich eines Auslasskanals bildet dabei die Turbinenkartusche sowohl eine (Einspritzdüsen-)Innenwand als auch eine (Einspritzdüsen-)Außenwand des Turbinengehäuses, während die Innenwand im Bereich des Spiralgehäuses von der Innenschale desselben und die Außenwand von der Außenschale desselben gebildet werden, sofern das Spiralgehäuse in zweischalig aufgebaut ist. Durch die leichte Ausbildung des Spiralgehäuses kann das Turbinengehäuse insgesamt deutlich leichter ausgebildet werden, wodurch die erfindungsgemäße Ladeeinrichtung insgesamt ein geringeres Gewicht aufweist. Zudem wird durch die vorzugsweise zweischalige und insbesondere schlecht wärmeleitende Ausbildung des Spiralgehäuses eine Temperatur eines einem Turbinenrad zugeführten Abgasstroms in nur vergleichsweise geringem Maße reduziert, wodurch sich ein mit der erfindungsgemäßen Ladeeinrichtung aufgeladener Verbrennungsmotor, insbesondere während einer Kaltstartphase, schneller aufheizt und dadurch auch einen sich in einem Abgasstrang befindlichen Katalysator schneller erwärmt, so dass dieser schneller seine volle Reinigungswirkung entfalten kann. Aufgrund der Tatsache, dass in dem leichten Spiralgehäuse auch deutlich weniger Wärmeenergie gespeichert werden kann, muss auch nach einem Abschalten des Verbrennungsmotors und dadurch nach einem Abschalten der Ladeeinrichtung nicht befürchtet werden, dass noch in der Ladeeinrichtung befindliches Lageröl verkokt. Hierzu besitzt nämlich das Spiralgehäuse zu wenig Masse und kann aus diesem Grund nicht die für eine Verkokung des Öls erforderliche Wärmeenergie speichern und später abgeben. Von besonderem Vorteil ist aber auch, dass durch das vergleichsweise leichte Turbinengehäuse die gesamte Ladeeinrichtung deutlich leichter aufgebaut werden kann und dadurch weniger wiegt, wodurch beim Betrieb des Verbrennungsmotors weniger Kraftstoff verbraucht und dadurch auch weniger CO2-Emissionen erzeugt werden.The present invention is based on the general idea of forming a turbine housing of a charging device from a one-piece and formed as a casting turbine cartridge and a spiral housing connected thereto. The turbine cartridge forms a support frame for the entire turbine housing, wherein the preferably constructed of an inner shell and an outer shell spiral housing between its inner and outer shell has a defined gap. In the region of a connection to a positional housing as well as in the region of an outlet channel, the turbine cartridge forms both an (injector) inner wall and an (injector) outer wall of the turbine housing, while the inner wall in the region of the volute casing of the inner shell of the same and the outer wall of the outer shell thereof are formed, provided that the spiral housing is constructed in two-shelled. Due to the lightweight design of the spiral housing, the turbine housing can be made much easier overall, whereby the charging device according to the invention has a total of a lower weight. In addition, a temperature of a turbine wheel supplied exhaust gas flow is reduced in only a comparatively small extent by the preferably bivalve and in particular poor heat conducting design of the volute casing, whereby a supercharged with the charging device according to the invention internal combustion engine, especially during a cold start phase, heats up faster and thereby also in an exhaust line catalyst heats faster, so that it can develop its full cleaning effect faster. Due to the fact that significantly less heat energy can be stored in the lightweight volute casing, even after a shutdown of the internal combustion engine and thus after switching off the charging device, it is not to be feared that the bearing oil still contained in the charging device becomes coked. For this purpose, namely, the spiral housing has too little mass and can not save the necessary for a coking of the oil heat energy for this reason and later deliver. Of particular advantage, however, is that the entire charging device can be constructed significantly lighter and thereby weighs less, which consumes less fuel during operation of the internal combustion engine and thereby less CO 2 emissions are generated by the relatively lightweight turbine housing.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, sind die Innenschale und/oder die Außenschale aus Metall, insbesondere aus Stahlblech, ausgebildet. Derartige Stahlbleche bieten dabei den großen Vorteil, im Vergleich zu Gehäuseteilen aus Gusswerkstoffen vergleichsweise leicht zu bauen. Durch eine Ausbildung der Innen- und/oder der Außenschale aus Metall kann darüber hinaus ein Berstverhalten bei einem Versagen des Turbinenrades günstig beeinflusst werden.at an advantageous embodiment of the invention Solution, are the inner shell and / or the outer shell made of metal, in particular made of sheet steel. such Steel sheets offer the big advantage, in comparison To housing parts made of cast materials comparatively easily to build. By forming the inner and / or the outer shell In addition, a bursting behavior at a metal can Failure of the turbine wheel are favorably influenced.
