Abstract
Description
Die Erfindung betrifft eine Abgasturbine einer Verbrennungskraftmaschine für ein Kraftfahrzeug, mit zumindest einer Laufschaufel und mit zumindest einer verstellbaren Leitschaufel, die stromaufwärts zu der Laufschaufel in einem Strömungsdurchlass angeordnet ist, wobei die Leitschaufel, entlang einer Längsachse der Leitschaufel gesehen, einen sich verändernden Querschnitt aufweist.The The invention relates to an exhaust gas turbine of an internal combustion engine for a motor vehicle, with at least one blade and with at least one adjustable vane upstream the blade is arranged in a flow passage is, wherein the vane, along a longitudinal axis of the Vane seen, a changing cross section having.
Aus dem Stand der Technik sind Turbinen mit verschiebbaren Leitschaufeln bekannt.Out The prior art turbines with sliding vanes known.
So
offenbart bspw. die
Ferner
ist aus dem Stand der Technik auch ein Turbolader mit einer Einrichtung
zur Regelung des Schluckvermögens der im Turbolader verbauten Turbine
bekannt, siehe
Die derzeit verwendeten Turbinen mit verstellbaren Leitschaufeln haben jedoch immer den Nachteil, dass sie der dreidimensional ungleichförmig ausgestalteten Strömung im Einlassbereich der Turbine nicht adäquat Rechnung zollen.The currently used turbines with adjustable vanes However, there is always the disadvantage that they are three-dimensionally non-uniform configured flow in the inlet area of the turbine not pay adequate attention.
Es ist daher die Aufgabe der vorliegenden Erfindung eine Abgasturbine zur Verfügung zu stellen, die bei unterschiedlichen Lastzuständen einen sehr hohen Wirkungsgrad aufweist. Es soll ferner eine Abgasturbine ohne die herkömmlichen Nachteile, allerdings bei hohem Wirkungsgrad erreicht werden.It Therefore, the object of the present invention is an exhaust gas turbine to provide that at different load conditions has a very high efficiency. It should also be an exhaust gas turbine without the conventional disadvantages, but at a high level Efficiency can be achieved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, das die Leitschaufel zusätzlich oder an Stelle des sich verändernden Querschnitts in Richtung der Längsachse in sich verdreht ausgestaltet ist.These The object is achieved according to the invention that the vane in addition to or instead of itself changing cross section in the direction of the longitudinal axis twisted in itself is designed.
Dadurch ist es möglich, die Anströmwinkel über die Turbinenradeintrittsbreite wirkungsgradoptimal zu gestalten. Die Strömungsverhältnisse des optional vorhandenen Leitgitterapparates können bei den dreidimensionalen Gegebenheiten zu einem verbesserten Wirkungsgrad führen. Eine gezielte Abstimmung des Leitgitters und der Ausgestaltung des Turbinenradeintritts über die gesamte Eintrittsbreite hinweg, kann durchgeführt werden, was dann zu einem besseren Wirkungsgrad führt. Eine solche Ausgestaltung empfiehlt sich insbesondere bei mehrflutigen Turbinen, insbesondere bei mehrflutigen Abgasturbinen. Der 3-D-Charakteristik der Strömung ist somit vermehrt Rechnung getragen. Der Wirkungsgrad erhöht sich.Thereby it is possible to overflow the angle of attack make the turbine wheel inlet width optimal in terms of efficiency. The flow conditions of the optional existing Leitgitterapparates can in the three-dimensional conditions lead to improved efficiency. A targeted Tuning of the guide grid and the design of the turbine wheel entry via the entire entrance width, can be performed which then leads to a better efficiency. Such Embodiment is particularly recommended for multi-flow turbines, especially in multi-flow exhaust gas turbines. The 3-D characteristic the flow is thus increasingly taken into account. Of the Efficiency increases.
Vorteilhafte Ausführungsformen werden in den Unteransprüchen beansprucht und nachfolgend näher erläutert.advantageous Embodiments are defined in the subclaims claimed and explained in more detail below.
Wenn die Leitschaufel in Strömungsrichtung gesehen eine Vorderkante und eine Hinterkante aufweist, wobei die Hinterkante an einem in Längsrichtung gesehen oberen und unteren Bereich von der Vorderkante wegweisende Vorsprünge aufweist, so wird ein besserer Strömungsverlauf erreicht. Vermehrte Schallentwicklung wird vermieden.If the guide vane seen in the flow direction, a leading edge and a trailing edge, wherein the trailing edge at an in Seen longitudinally upper and lower area of the front edge has pioneering projections, so is a better flow reached. Increased sound development is avoided.
Um einen gleichmäßigen Strömungsverlauf zu erreichen, ist es von Vorteil, wenn die Vorderkante kurvig ausgeformt ist.Around a uniform flow reach, it is advantageous if the leading edge formed curvy is.
Als besonders vorteilhaft hat es sich herausgestellt, wenn sich in einem weiteren Ausführungsbeispiel die Querschnittsfläche entlang der Längsachse der Leitschaufel senkrecht zur Längsachse verkleinert.When it has turned out to be particularly advantageous if it is in one Another embodiment, the cross-sectional area downsized along the longitudinal axis of the vane perpendicular to the longitudinal axis.
Eine weitere vorteilhafte Ausführungsform ist dadurch gekennzeichnet, dass die Vorderkante an einem Längsende der Leitschaufel weniger weit von der Rotationsachse der Leitschaufel entfernt ist, als an einem gegenüberliegenden Längsende.A further advantageous embodiment is characterized in that that the leading edge at one longitudinal end of the vane is less far from the axis of rotation of the vane, as at an opposite longitudinal end.
Wenn beide Längsenden der Vorderkante der Leitschaufel weniger weit von der Rotationsachse entfernt sind, als ein im mittleren Bereich der Vorderkante, so wird den im Randbereich der Strömung auftretenden Verzögerungseffekten adäquat Rechnung getragen.If both longitudinal ends of the leading edge of the vane less far away from the axis of rotation, as one in the middle Area of the leading edge, so is the occurring in the edge region of the flow Delay effects are adequately taken into account.
Um den Wirkungsgrad im Teillastbereich besonders gut beeinflussen zu können, ist es von Vorteil, wenn ein Schieber zur Strömungsregelung den Strömungsdurchlass verkleinernd bewegbar angeordnet ist.Around the efficiency in the partial load range particularly good influence can, it is advantageous if a slider for flow control the flow passage arranged to reduce movable is.
Besonders vorteilhaft ist dabei, wenn der Schieber die Leitschaufel zumindest abschnittsweise umhüllt.Especially it is advantageous if the slider at least the vane wrapped in sections.
Um über den gesamten Umfang des Turbinenrades einen gleichmäßigen Schubverlauf zu haben, ist es von Vorteil, wenn eine Vielzahl von äquidistant zueinander angeordneten Leitschaufeln in einem Turbinengehäuse angeordnet sind.To over the entire circumference of the turbine wheel a uniform Thrust course, it is advantageous when a variety of equidistant mutually arranged vanes in a turbine housing are arranged.
