Abstract
Description
Die Erfindung betrifft eine Turbine für einen Abgasturbolader der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a turbine for an exhaust gas turbocharger specified in the preamble of claim 1. Art.
Eine solche Turbine ist aus der
Es hat sich gezeigt, dass die Abdichtung des Spalts eine nicht unerhebliche Rolle für die gesamte Dichtheit der Turbine über eine hohe Lebensdauer hinweg spielt.It has been found that the sealing of the gap plays a not insignificant role for the entire tightness of the turbine over a long service life.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Turbine für einen Abgasturbolader der eingangs genannten Art derart weiterzuentwickeln, dass eine verbesserte Abdichtung des Spalts realisiert ist.It is therefore an object of the present invention to develop a turbine for an exhaust gas turbocharger of the type mentioned in such a way that an improved sealing of the gap is realized.
Diese Aufgabe wird durch eine Turbine für einen Abgasturbolader mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nichttrivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a turbine for an exhaust gas turbocharger having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Die Erfindung betrifft eine Turbine für einen Abgasturbolader mit einem Turbinengehäuse. Das Turbinengehäuse weist einen Aufnahmeraum auf, in welchem ein Turbinenrad der Turbine zumindest bereichsweise aufgenommen ist. Die Turbine weist eine Düse auf, welche mittels wenigstens einer ersten Wandung der Turbine begrenzt ist und über welche dem Turbinenrad Abgas, insbesondere zumindest im Wesentlichen in radialer Richtung, zuführbar ist. Mit anderen Worten erstreckt sich die Düse im Wesentlichen in radialer Richtung. Zwischen der ersten Wandung und einer zweiten Wandung des Turbinengehäuses ist ein Spalt gebildet, welcher mittels wenigstens eines Dichtungselements zumindest im Wesentlichen abgedichtet ist.The invention relates to a turbine for an exhaust gas turbocharger with a turbine housing. The turbine housing has a receiving space in which a turbine wheel of the turbine is received at least partially. The turbine has a nozzle which is delimited by means of at least one first wall of the turbine and via which exhaust gas can be fed to the turbine wheel, in particular at least substantially in the radial direction. In other words, the nozzle extends substantially in the radial direction. Between the first wall and a second wall of the turbine housing, a gap is formed, which is at least substantially sealed by means of at least one sealing element.
Erfindungsgemäß ist das Dichtungselement zwischen einem den Spalt einerseits in axialer Richtung des Turbinenrads begrenzenden ersten Wandungsbereich der ersten Wandung und einem den Spalt andererseits in axialer Richtung begrenzenden zweiten Wandungsbereich der zweiten Wandung angeordnet. Mit anderen Worten begrenzt der erste Wandungsbereich der ersten Wandung den Spalt einerseits in axialer Richtung. Der zweite Wandungsbereich der zweiten Wandung begrenzt den Spalt in axialer Richtung andererseits. Das Dichtungselement ist dabei einerseits an dem ersten Wandungsbereich zumindest mittelbar abgestützt und andererseits an dem zweiten Wandungsbereich zumindest mittelbar abgestützt. Dadurch ist eine besonders effiziente und verbesserte Abdichtung des Spalts realisiert, wodurch die Turbine insgesamt eine verbesserte Dichtheit aufweist. Daraus resultiert eine besonders hohe Lebensdauer der Turbine. Die verbesserte Abdichtung des Spalts führt auch zu einer verbesserten Ausgewogenheit hinsichtlich Toleranzen der Turbine. Mit anderen Worten ist die Turbine so besonders unempfindlich gegenüber Toleranzen, was ihrer Lebensdauer, d. h. ihrer Funktionalität auch über eine hohe Lebensdauer hinweg zugute kommt.According to the invention, the sealing element is arranged between a first wall region of the first wall defining the gap on the one hand in the axial direction of the turbine wheel and a second wall region of the second wall bounding the gap in the axial direction. In other words, the first wall region of the first wall limits the gap on the one hand in the axial direction. The second wall region of the second wall limits the gap in the axial direction on the other. The sealing element is on the one hand at least indirectly supported on the first wall region and on the other hand at least indirectly supported on the second wall region. As a result, a particularly efficient and improved sealing of the gap is realized, as a result of which the turbine as a whole has improved tightness. This results in a particularly long service life of the turbine. The improved sealing of the gap also results in an improved balance in turbine tolerances. In other words, the turbine is so insensitive to tolerances, which increases its service life, ie. H. their functionality also benefits over a long service life.
Bevorzugt sind der erste Wandungsbereich und der zweite Wandungsbereich in axialer Richtung in gegenseitiger Überdeckung angeordnet. Dadurch ist eine besonders effiziente Abdichtung des Spalts und damit eine besonders hohe Dichtheit der Turbine realisiert. Die verbesserte Abdichtung der erfindungsgemäßen Turbine ist dabei auf bauraum- sowie kostengünstiger Weise mit einer nur sehr geringen Teileanzahl geschaffen, was den Bauraumbedarf und die Kosten des gesamten Abgasturboladers gering hält.Preferably, the first wall region and the second wall region are arranged in the axial direction in mutual overlap. As a result, a particularly efficient sealing of the gap and thus a particularly high density of the turbine is realized. The improved sealing of the turbine according to the invention is created in a space-and cost-effective manner with only a very small number of parts, which keeps the space requirements and the cost of the entire exhaust gas turbocharger low.
Bei einer vorteilhaften Ausführungsform der Erfindung weist wenigstens einer der Wandungsbereiche, der erste Wandungsbereich und/oder der zweite Wandungsbereich, einen Absatz auf, an welchem das Dichtungselement in radialer Richtung abgestützt ist. Der Absatz, welcher auch ein Anschlag sein kann, dient somit als Positionierhilfe für das Dichtungselement, so dass das Dichtungselement insbesondere während der Montage der Turbine zeit- und kostengünstig in seiner gewünschte und die Dichtheit gewährleistende Position angeordnet werden kann. Dies kommt somit einer zeit- und kostengünstigen Montage bzw. Herstellung der Turbine zugute. Vorteilhafterweise ist der Absatz auf einer dem Turbinenrad in radialer Richtung zugewandten Seite des Dichtungselements angeordnet, woraus eine besonders zeit- und kostengünstige Montage des Dichtungselements und damit der gesamten Turbine resultiert.In an advantageous embodiment of the invention, at least one of the wall regions, the first wall region and / or the second wall region, a step on which the sealing element is supported in the radial direction. The heel, which can also be a stop, thus serves as a positioning aid for the sealing element, so that the sealing element can be arranged in particular time and cost in its desired and tightness-ensuring position, in particular during assembly of the turbine. This therefore benefits a time-consuming and cost-effective installation or production of the turbine. Advantageously, the shoulder is arranged on a turbine wheel in the radial direction facing side of the sealing element, resulting in a particularly time-consuming and cost-effective installation of the sealing element and thus the entire turbine results.
In weiterer vorteilhafter Ausgestaltung ist das Dichtungselement aus einem oxydkeramischen Werkstoff gebildet. Dadurch ist eine besonders hohe Dichtheit der Turbine auch über eine sehr hohe Lebensdauer hinweg gewährleistet.In a further advantageous embodiment, the sealing element is formed from an oxide-ceramic material. As a result, a particularly high density of the turbine is ensured even over a very long lifetime.
Als weiterhin vorteilhaft hat es sich gezeigt, wenn wenigstens ein Halteelement, insbesondere ein Haltering, vorgesehen ist, unter dessen Vermittlung das Dichtungselement zwischen den Wandungsbereichen gehalten, insbesondere an den Wandungsbereichen abgestützt, ist. Dadurch ist eine besonders einfache, zeit- und kostengünstige Montage des Dichtungselements dargestellt.As further advantageous, it has been shown, if at least one retaining element, in particular a retaining ring is provided, under the intermediary of which the sealing element between the Wall regions held, in particular supported on the wall areas, is. As a result, a particularly simple, time-consuming and cost-effective installation of the sealing element is shown.
