Abstract
Description
Die vorliegende Erfindung betrifft einen Drallerzeuger zur drallbeaufschlagten Anströmung eines Verdichterlaufrads einer Ladeeinrichtung, insbesondere eines Abgasturboladers für eine Brennkraftmaschine, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung betrifft außerdem eine Ladeeinrichtung, insbesondere einen Abgasturbolader, mit einem derartigen Drallerzeuger.The The present invention relates to a swirl generator for spin-loaded Flow of a compressor impeller of a charging device, in particular an exhaust gas turbocharger for an internal combustion engine, with the features of the preamble of claim 1. The invention also relates to a charging device, in particular a Exhaust gas turbocharger, with such a swirl generator.
Bei einer Ladeeinrichtung, die mit einem Verdichterlaufrad arbeitet, also insbesondere bei einem Abgasturbolader, kann der Wirkungsgrad verbessert werden, wenn stromauf des Verdichterlaufrads ein Drallerzeuger positioniert wird, mit dessen Hilfe die dem Verdichterlaufrad zugeführte Strömung mit einem Drall beaufschlagt werden kann. Durch den Drall erhält die Absolutgeschwindigkeit der dem Verdichterlaufrad zugeführten Luftströmung eine tangentiale Komponente. Diese Tangentialkomponente der Absolutgeschwindigkeit reduziert den Lufteintrittswinkel auf einen Wert kleiner als 90°. Hierdurch wird die Relativgeschwindigkeit am Eintritt des Verdichterlaufrads reduziert, was bei hohen Verdichterdrehzahlen eine signifikante Erhöhung des Verdichterwirkungsgrad mit sich bringt.at a loading device that works with a compressor wheel, So especially in an exhaust gas turbocharger, the efficiency be improved if upstream of the compressor impeller, a swirl generator is positioned, with the help of which the compressor impeller supplied Flow can be applied to a swirl. By the twist receives the absolute velocity of the compressor impeller supplied air flow a tangential component. This tangential component of the absolute velocity is reduced the air inlet angle to a value less than 90 °. As a result, the relative speed at the entrance of the compressor wheel reduced, which is a significant at high compressor speeds Increase in the compressor efficiency brings with it.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Drallerzeuger bzw. für eine damit ausgestattete Ladeeinrichtung eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie vergleichsweise preiswert realisierbar ist, eine hinreichende Stabilität besitzt und eine präzise Einstellung des Abströmwinkels ermöglicht.The The present invention addresses the problem of for a swirl generator or for a so equipped Charger to provide an improved embodiment, which is characterized in particular by the fact that it comparatively reasonably priced, adequate stability owns and a precise adjustment of the outflow angle allows.
Dieses Problem wird erfindungsgemäß durch den Gegenstand der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claims. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Leitschaufeln in axialer Richtung zweiteilig auszuführen, so dass jede Leitschaufel einen anströmseitigen starren Schaufelabschnitt und einen abströmseitigen elastisch verformbaren, flexiblen Schaufelabschnitt besitzt. Während der jeweilige starre Schaufelabschnitt mit einer den jeweiligen Strömungskanal seitlich begrenzenden Wand fest verbunden ist, sind die flexiblen Schaufelabschnitte am jeweiligen zugehörigen starren Schaufelabschnitt befestigt und auf geeignete Weise mit einer Stelleinrichtung zum Einstellen des Abströmwinkels gekoppelt. Durch diese Bauweise besitzt der Drallerzeuger eine hohe Stabilität, da er durch die anströmseitigen starren Schaufelabschnitte intensiv ausgesteift ist. Die mit der Stelleinrichtung gekoppelten flexiblen Schaufelabschnitte ermöglichen eine präzise Einstellung des jeweils gewünschten Abströmwinkels. Zusätzlich vereinfacht sich die Herstellung, da es bspw. möglich ist, die starren Schaufelabschnitte zusammen mit der Kanalwand aus einem Stück zu gießen. Darüber hinaus sind die flexiblen Schaufelabschnitte hinsichtlich einer Wärmeübertragung von der Kanalwand entkoppelt, so dass eine Wärmeübertragung auf die flexiblen Schaufelabschnitte erheblich reduziert ist. Insbesondere vereinfacht sich dadurch die Herstellung der flexiblen Schaufelabschnitte aus einem geeigneten Kunststoff.The Invention is based on the general idea, the vanes in the axial direction in two parts, so that each Guide vane an upstream rigid blade section and a downstream elastic deformable, flexible Scoop section possesses. While the respective rigid Blade section with a respective flow channel firmly bounding side wall, are the flexible Blade sections attached to the respective associated rigid blade section and suitably with adjusting means for adjustment coupled to the outflow angle. Owned by this construction the swirl generator a high stability, since it by the on the inflow-side rigid blade sections stiffened intensively is. The coupled with the actuator flexible blade sections allow precise adjustment of each desired outflow angle. additionally simplifies the production, since it is, for example, possible, the rigid blade sections together with the channel wall of a Piece to pour. In addition, are the flexible blade sections in terms of heat transfer decoupled from the duct wall, allowing a heat transfer to the flexible blade sections is significantly reduced. Especially This simplifies the manufacture of the flexible blade sections made of a suitable plastic.
Zur Kopplung mit der Stelleinrichtung können die flexiblen Schaufelabschnitte entsprechend einer vorteilhaften Ausführungsform mit Betätigungselementen ausgestattet sein, die radial aus dem Strömungskanal herausgeführt sind und mit der Stelleinrichtung zusammenwirken. Zum Verstellen des Abströmwinkels können die Betätigungselemente in der Umfangsrichtung relativ zur Kanalwand verstellt werden, wodurch sich auch die Relativlage zwischen den flexiblen Schaufelabschnitten und den zugehörigen starren Schaufelabschnitten entsprechend verändert. In der Folge wird dabei der Abströmwinkel der Leitschaufeln verändert.to Coupling with the actuator can be the flexible Blade sections according to an advantageous embodiment be equipped with actuators that radially are led out of the flow channel and interact with the actuator. For adjusting the outflow angle can the actuators in the circumferential direction be adjusted relative to the channel wall, which also causes the relative position between the flexible blade sections and the associated rigid ones Shovel sections changed accordingly. Subsequently In this case, the outlet angle of the guide vanes is changed.
Besonders vorteilhaft ist eine Ausführungsform, bei welcher die flexiblen Schaufelabschnitte radial innen eine kleinere axiale Länge aufweisen als radial außen. Hierdurch erhalten die flexiblen Schaufelabschnitte eine im Wesentlichen dreieckige Kontur, wobei eine der Ecken durch das innen liegende Ende des jeweiligen flexiblen Schaufelabschnitts gebildet ist.Especially advantageous is an embodiment in which the flexible Blade sections radially inward a smaller axial length have as radially outside. This gives the flexible Blade portions of a substantially triangular contour, wherein one of the corners through the inside end of the respective flexible Blade portion is formed.
