Aus der europäischen Patentanmeldung EP 0 781 908 A2, von der diese Erfindung ausgeht, ist ein Abgasturbolader mit einem Maschinengehäuse bekannt. In dem Maschinengehäuse ist ein Lagergehäuse angeordnet, in dem eine Antriebswelle drehbar gelagert ist. Stirnseitig an die Antriebswelle kann einerseits ein Verdichterrad und andererseits ein Turbinenrad montiert werden. Bei der Montage des Abgasturboladers werden das Verdichtergehäuse und das Turbinengehäuse derart miteinander verschraubt, dass zwischen Verdichter- und Turbinengehäuse das Lagergehäuse eingeklemmt ist. In dieses Lagergehäuse ist eine Antriebswelle einführbar, an die verdichter- seitig ein Verdichterrad und turbinenseitig ein Turbinenrad montiert wird.From the European patent application EP 0 781 908 A2, from which this invention proceeds, an exhaust gas turbocharger with a machine housing is known. In the machine housing, a bearing housing is arranged, in which a drive shaft is rotatably mounted.

During assembly of the exhaust gas turbocharger, the compressor housing and the turbine housing are screwed together such that between the compressor and turbine housing, the bearing housing is clamped. In this bearing housing, a drive shaft is inserted, on the compressor side, a compressor and turbine side turbine wheel is mounted.
Nachteilig an dem gattungsgemäßen Abgasturbolader ist die relativ aufwendige und somit teure Fertigung.A disadvantage of the generic exhaust gas turbocharger is the relatively expensive and therefore expensive production.
Aufgabe der vorliegenden Erfindung ist es, eine einfachere und kostengünstigere Montage für einen gattungsgemäßen Abgasturbolader aufzuzeigen.Object of the present invention is to show a simpler and cheaper installation for a generic exhaust gas turbocharger.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 dadurch gelöst, dass das Lagergehäuse gemeinsam mit der Antriebswelle und mit dem Turbinenrad und/oder mit dem Verdichterrad als vormontierbare Baugruppe in das Maschinengehäuse einbringbar ist. Durch die erfindungsgemäße Ausgestaltung ist die vormontierte Baugruppe in einem einzigen Arbeitsgang in das Maschinengehäuse des Abgasturboladers einbringbar, wodurch weitere Fertigungsschritte entfallen können.This object is solved by the features in the characterizing part of patent claim 1, characterized in that the bearing housing together with the Drive shaft and with the turbine wheel and / or with the compressor as a pre-assembled assembly in the machine housing can be introduced. Due to the inventive design, the preassembled module in a single operation in the engine housing of the exhaust gas turbocharger can be introduced, whereby further manufacturing steps can be omitted.
Die Ausgestaltungen gemäß Patentanspruch 2 sind besonders bevorzugte Ausführungsbeispiele, wo entweder nur eine Gleitlagerung oder nur eine Wälzlagerung oder eine kombinierte Gleit- und Wälzlagerung vorgesehen werden kann.The embodiments according to claim 2 are particularly preferred embodiments, where either only a plain bearing or only a rolling bearing or a combined sliding and rolling bearings can be provided.
Mit den Ausgestaltungen gemäß den Patentansprüchen 3 bis 5 ist es möglich, den Abgasturbolader direkt an die Brennkraftmaschine zu koppeln, wodurch in vorteilhafter weise separate Leitungen für Schmiermittel bzw. Kühlmittel entfallen können. Auch diese Ausgestaltung führt zu einer zusätzlichen, erheblichen Kosteneinsparung.With the embodiments according to the claims 3 to 5, it is possible to couple the exhaust gas turbocharger directly to the internal combustion engine, which can advantageously account for separate lines for lubricant or coolant. This embodiment also leads to an additional, significant cost savings.
Die Ausgestaltung gemäß Patentanspruch 6 verhindert, dass Schmiermittel aus dem Lagerbereich in den Turbinenbereich oder den Verdichterbereich kriechen kann.The embodiment according to claim 6 prevents lubricant from the storage area can crawl in the turbine area or the compressor area.
Die Ausgestaltung gemäß Patentanspruch 7 ist eine erste besonders bevorzugte Ausführungsvariante.The embodiment according to claim 7 is a first particularly preferred embodiment.
Die Ausgestaltung gemäß Patentanspruch 8 ist eine zweite besonders bevorzugte Ausführungsvariante.The embodiment according to claim 8 is a second particularly preferred embodiment.
Im Folgenden ist die Erfindung anhand eines besonders bevorzugten Ausführungsbeispieles in einer einzigen Figur näher erläutert:In the following the invention is explained in more detail with reference to a particularly preferred embodiment in a single figure:
Fig. 1 zeigt einen Schnitt durch einen erfindungsgemäß ausgestalteten Abgasturbolader. Fig. 1 zeigt einen Schnitt durch einen erfindungsgemäß ausgestalteten, dreidimensional dargestellten Abgasturbolader 1. Der Abgasturbolader 1 weist ein Maschinengehäuse 2 auf, in dem ein Lagergehäuse 3 einbringbar ist. In dem Lagergehäuse 3 ist eine Antriebswelle 4 drehbar angeordnet, wobei tur- binenseitig ein Turbinenrad 6 an der Antriebswelle 4 montiert ist. Ein verdich- terseitig an die Antriebswelle 4 montierbares, nicht dargestelltes Verdichterrad 5 ist zur Lageerkennung mit der Ziffer 5 dargestellt.Fig. 1 shows a section through an inventively designed exhaust gas turbocharger. 1 shows a section through an exhaust gas turbocharger 1 designed according to the invention and shown in three dimensions. The exhaust gas turbocharger 1 has a machine housing 2 in which a bearing housing 3 can be introduced. In the bearing housing 3, a drive shaft 4 is rotatably arranged, wherein turbo turbine side 6 is mounted on the drive shaft 4 turbine side. A compressor wheel 5, which can be mounted on the compressor shaft 4 and is not shown on the compressor side, is shown with the number 5 for position detection.
Erfindungsgemäß können das Lagergehäuse 3, die Antriebswelle 4 sowie das Turbinenrad 6 und/oder Verdichterrad 5 als vormontierte Baugruppe in das Maschinengehäuse 2 eingeführt werden. Bei der Montage wird das Lagergehäuse 3 gemeinsam mit der Antriebswelle 4 und dem Turbinenrad 6 und/oder dem Verdichterrad in das Maschinengehäuse 2 eingeführt und anschließend wird ein Verdichtergehäuse 13 verdichterseitig an das Maschinengehäuse 2 angeordnet. Damit das Lagergehäuse 3 in das Maschinengehäuse 2 einbringbar ist, weist es gestufte Durchmesser auf, die von der Turbinenseite zur Verdichterseite größer werden, wobei das Turbinenrad 6 einen kleineren oder gleichen Außendurchmesser aufweist wie ein kleinste Lagergehäusedurchmesser. Selbstverständlich könnte auch verdichterseitig der kleinste Lagergehäusedurchmesser angeordnet sein.According to the invention, the bearing housing 3, the drive shaft 4 and the turbine wheel 6 and / or compressor wheel 5 can be introduced as a preassembled module into the machine housing 2. During assembly, the bearing housing 3 is introduced together with the drive shaft 4 and the turbine wheel 6 and / or the compressor in the machine housing 2 and then a compressor housing 13 is arranged on the compressor side of the machine housing 2. In order for the bearing housing 3 to be able to be introduced into the machine housing 2, it has stepped diameters which increase from the turbine side to the compressor side, with the turbine wheel 6 having a smaller or the same outer diameter than a smallest bearing housing diameter. Of course, the smallest bearing housing diameter could also be arranged on the compressor side.
Die Antriebswelle 4 kann in dem Lagergehäuse 3 beispielsweise nur gleitgelagert oder nur wälzgelagert oder auch in einer Mischform aus Gleit- und Wälzlagerung gelagert sein.The drive shaft 4 may, for example, only be slide-mounted in the bearing housing 3, or may only be stored roller-mounted or also stored in a mixed form of sliding and rolling bearings.
Wie in Fig. 1 erkennbar ist, ist das Turbinengehäuse, welches gleichzeitig das Maschinengehäuse 2 ist, integraler Bestandteil eines Abgaskrümmers 10 einer nicht dargestellten Brennkraftmaschine. Hierfür weisen das Maschinengehäuse 2 und das Lagergehäuse 3 zumindest einen Schmiermittelkanal 7 zur Zufuhr von Schmiermittel zur Lagerung und einen Schmiermittelkanal 7 zur Abfuhr von Schmiermittel auf. Darüber hinaus weist das Maschinenge- häuse 2, bzw. der Abgaskrümmer 10 zumindest einen Kühlmittelkanal 8 auf, wobei der Schmiermittelkanal 7 und/oder der Kühlmittelkanal 8 zu einem Schmiermittelkanal und/oder einem Kühlmittelkanal der Brennkraftmaschine korrespondieren. Hierdurch entfallen sämtliche externen Schläuche zur Kühlmittel- bzw. Schmiermittelführung. Dies ermöglicht eine weitere kostengünstige Ausgestaltung des erfindungsgemäßen Abgasturboladers.As can be seen in Fig. 1, the turbine housing, which is the machine housing 2 at the same time, an integral part of an exhaust manifold 10 of an internal combustion engine, not shown. For this purpose, the machine housing 2 and the bearing housing 3 at least one lubricant channel 7 for the supply of lubricant for storage and a lubricant channel 7 for the removal of lubricant. In addition, the machine housing 2, and the exhaust manifold 10 at least one coolant channel 8, wherein the lubricant channel 7 and / or the coolant channel 8 correspond to a lubricant channel and / or a coolant channel of the internal combustion engine. This eliminates all external hoses for coolant or lubricant management. This allows a further cost-effective embodiment of the exhaust gas turbocharger according to the invention.
Um ein Austreten von Schmiermittel turbinenseitig oder verdichterseitig zu vermeiden, ist zwischen dem Maschinengehäuse 2 und dem Lagergehäuse 3 zumindest ein umlaufendes Dichtelement 9 vorgesehen, welches vorzugsweise turbinen- und verdichterseitig Anwendung findet.In order to avoid leakage of lubricant on the turbine side or the compressor side, at least one circumferential sealing element 9 is provided between the machine housing 2 and the bearing housing 3, which is preferably used on the turbine and compressor side.
In einem weiteren, besonders bevorzugten Ausführungsbeispiel ist es auch möglich, den Abgasturbolader 1 teilweise oder vollständig in einen Zylinderkopf der Brennkraftmaschine zu integrieren.In a further, particularly preferred embodiment, it is also possible to integrate the exhaust gas turbocharger 1 partially or completely into a cylinder head of the internal combustion engine.
Um zu große Abgas-Massenströme über das Turbinenrad 6 des Abgasturboladers 1 zu vermeiden, weist der Abgasturbolader 1 ferner turbinenseitig einen Bypass 12 auf, der von einer Bypassklappe 11 verschließbar ist. Eine Strömungsrichtung des Abgases ist durch Pfeile schematisch dargestellt, wobei die Abgase, nachdem sie das Turbinengehäuse verlassen haben, durch eine Abgasreinigungsanlage 15 strömen. Des Weiteren ist die Bypassklappe 11 von einem Stellelement 14, im vorliegenden Ausführungsbeispiel eine Unterdruckdose, betätigbar, um den Abgasturbolader jederzeit an die Betriebsbedingungen der Brennkraftmaschine anzupassen.In order to avoid excessive exhaust gas mass flows via the turbine wheel 6 of the exhaust gas turbocharger 1, the exhaust gas turbocharger 1 also has a bypass 12 on the turbine side, which can be closed by a bypass flap 11. A flow direction of the exhaust gas is shown schematically by arrows, wherein the exhaust gases, after they have left the turbine housing, flow through an exhaust gas purification system 15. Furthermore, the bypass flap 11 of an adjusting element 14, in the present embodiment, a vacuum box, operable to adapt the exhaust gas turbocharger at any time to the operating conditions of the internal combustion engine.
Durch die erfindungsgemäße Ausgestaltung kann der Abgaskrümmer 10 bzw. das Maschinengehäuse 2 auch besonders kostengünstig aus einem Aluminiumwerkstoff oder Leichtmetall gegossen werden. Selbstverständlich können insbesondere Größenverhältnisse von diesem besonders bevorzugten Ausführungsbeispiel in anderen Ausführungsbeispielen deutlich variieren. Auch die Anzahl der Dichtelemente 9, Lage oder Anordnung der Kühlmittel- kanäle 8, bzw. der Schmiermittelkanäle 7 können vom vorliegenden Ausführungsbeispiel deutlich abweichen.As a result of the configuration according to the invention, the exhaust manifold 10 or the machine housing 2 can also be cast particularly cost-effectively from an aluminum material or light metal. Of course, in particular size ratios of this particularly preferred embodiment can vary significantly in other embodiments. The number of sealing elements 9, location or arrangement of the coolant Channels 8, and the lubricant channels 7 may differ significantly from the present embodiment.
Insgesamt zeichnet sich der erfindungsgemäße Abgasturbolader dadurch aus, dass der Lagerstuhl als vormontierte Baugruppe in das Maschinengehäuse 2, vorzugsweise ein Leichtmetallgussgehäuse, geschoben werden kann und darüber hinaus keine externen Leitungen zur Medienversorgung benötigt werden. Das Lagergehäuse 3 bzw. die Lagerstühle bekommen den Schmiermittelvorlauf und Schmiermittelablauf über Bohrungen und Kanäle im Gussgehäuse.Overall, the exhaust gas turbocharger according to the invention is characterized in that the bearing block can be pushed as a preassembled module in the machine housing 2, preferably a light metal casting housing, and beyond no external lines for media supply are needed. The bearing housing 3 or the bearing chairs get the lubricant flow and lubricant outlet through holes and channels in the cast housing.
Durch diese erfindungsgemäße Ausgestaltung ist eine besonders einfache und kostengünstige Fertigung des Abgasturboladers möglich. By this embodiment of the invention, a particularly simple and cost-effective production of the exhaust gas turbocharger is possible.
