Abstract
Description
Die Erfindung bezieht sich auf einen Turbolader bei dem innerhalb eines im Turbinengehäuse angeordneten, das Turbinenrad ringförmig umfassenden Radialspaltes zur Zuführung von Ab- bzw. Treibgasen zum Turbinenrad Leitschaufeln vorgesehen sind, die an einem zur Turbinenradachse zentrischen Trägerring angeordnet sind, welcher im Wesentlichen eine der Radialwände des Radialspaltes bildet und von einer eine innere Umfangszone am Trägerring axial beaufschlagenden ringförmigen Tellerfeder axial in Richtung des Turbinenrades gegen zumindest einen Anschlag am oder im Turbinengehäuse gespannt wird, wobei die Leitschaufeln vorzugsweise für eine variable Turbinengeometrie um zur Turbinenradachse im wesentlichen parallele Achsen schwenkbar sind.The The invention relates to a turbocharger in which arranged in the turbine housing, the turbine wheel annular comprehensive radial gap for the supply of exhaust gas or propellant gases are provided to the turbine wheel vanes, which are connected to a for Turbine wheel axis are arranged centric carrier ring, which is essentially one of the radial walls of the radial gap forms and of an inner peripheral zone on the support ring axially acting annular plate spring axially in Direction of the turbine wheel against at least one stop on or is stretched in the turbine housing, with the vanes preferably for a variable turbine geometry around the Turbinenradachse substantially parallel axes are pivotable.
Ein
derartiger Turbolader ist Gegenstand der
Bei diesem bekannten Turbolader hat die Tellerfeder eine Mehrfachfunktion, einerseits dient dazu, den Trägerring in die Sollposition zu spannen, andererseits dient die Tellerfeder als Hitzeschild des axial an das Turbinengehäuse anschließenden Lagergehäuses, welches das stationäre Widerlager der Tellerfeder bildet.at this known turbocharger, the diaphragm spring has a multiple function, on the one hand serves to the carrier ring in the desired position to tension, on the other hand serves the plate spring as a heat shield of the axial to the turbine housing subsequent bearing housing, which forms the stationary abutment of the plate spring.
Aus
der
Die Abdichtung des die Steuerelemente für die Leitschaufeln aufnehmenden Ringraumes auf der vom Turbinengehäuse abgewandten Stirnseite des Trägerringes wird durch axiale Verspannung des Trägerrings am Lagergehäuse gewährleistet.The Sealing of the controls for the vanes receiving annular space facing away from the turbine housing Front side of the carrier ring is by axial tension ensures the carrier ring on the bearing housing.
Der
aus der
Auch
der Turbolader der
Deshalb ist es Aufgabe der Erfindung, einen Turbolader zu schaffen, der sich einerseits durch hohe thermische Belastbarkeit und andererseits durch vergleichsweise geringen Herstellungsaufwand auszeichnet.Therefore It is an object of the invention to provide a turbocharger, the on the one hand by high thermal capacity and on the other hand by comparatively low production costs.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Trägerring eine die zugewandte Stirnseite des Turbinenrades radial im Wesentlichen vollständig überlappende ab- bzw. treibgasseitige Stirnfläche aufweist.These The object is achieved according to the invention the carrier ring has a facing end side of the Turbine wheel radially substantially completely overlapping Has ab- or propellant gas end face.
Die Erfindung beruht auf dem allgemeinen Gedanken, den Trägerring in grundsätzlich bekannter Weise mittels einer ringförmigen Tellerfeder in seine Solllage zu spannen, wobei jedoch die Tellerfeder, die zusätzlich die Funktion einer Dichtung zwischen Trägerring und Lagergehäuse übernehmen kann, aufgrund einer besonderen Ausformung des Trägerringes gegen eine direkte Beaufschlagung durch den das Turbinenrad treibenden Ab- bzw. Treibgasstrom geschützt wird.The Invention is based on the general idea of the carrier ring in a basically known manner by means of an annular Clamp plate spring in its desired position, but with the plate spring, the In addition, the function of a seal between the carrier ring and bearing housing can take over, due to a special shape of the carrier ring against a direct Exposure protected by the turbine or the driving exhaust gas or propellant stream becomes.
Auf diese Weise kann für die Tellerfeder auch bei deren Herstellung aus preiswerten Federmaterialien eine hohe Lebensdauer gewährleistet werden.On This way can for the diaphragm spring in their production Made of low-cost spring materials ensures a long life become.
Da der Trägerring durch die Tellerfeder axial in seine Solllage gespannt wird, kann er den durch thermische Belastung der angrenzenden Bauteile verursachten Wärmedehnungen dieser Bauteile ohne weiteres folgen, ohne dass an oder in den Bauteilen übermäßige Verspannungen auftreten können.There the carrier ring through the plate spring axially into its desired position it can be tensioned by thermal stress of the adjacent Components caused thermal expansion of these components without further follow without excessive on or in the components Tension can occur.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, dass auf der dem Trägerring gegenüberliegenden Seite des Radialspaltes eine die Innenseite des Turbinengehäuses überdeckende ringscheibenförmige Deckscheibe mit daran angeordneten Distanzkörpern vorgesehen ist, gegen die der Trägerring mittels der Tellerfeder gespannt ist, wobei gleichzeitig die Deckscheibe gegen die Innenseite des Turbinengehäuses gespannt wird.According to a particularly preferred embodiment of the invention can be provided that on the support ring opposite Side of the radial gap is provided on the inside of the turbine housing covering annular disk-shaped cover plate with spacers arranged thereon, against which the carrier ring is clamped by the plate spring, at the same time the cover plate is clamped against the inside of the turbine housing.
Hier ist besonders vorteilhaft, dass die den Radialspalt begrenzenden Teile ein segmentiertes Ensemble bilden, welches Relativbewegungen seiner Teile zulässt, so dass auch bei extremer thermischer Beanspruchung keine Verspannungen auftreten können.Here is particularly advantageous that the limiting the radial gap Parts form a segmented ensemble, which relative movements allows its parts, so even at extreme thermal Stress no tension can occur.
Alternativ können die Distanzelemente auch am Trägerring angeordnet sein und mit der Deckscheibe anschlagartig zusammenwirken.alternative The spacers can also on the carrier ring be arranged and interact with the cover disc stop-like.
Im Übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche und die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der eine besonders bevorzugte Ausführungsform näher beschrieben wird.Furthermore is in terms of preferred features of the invention to the claims and the following explanation of the drawing, based of a particularly preferred embodiment closer is described.
Schutz wird nicht nur für angegebene oder dargestellte Merkmalskombinationen, sondern auch für prinzipiell beliebige Kombinationen der angegebenen oder dargestellten Einzelmerkmale beansprucht.protection is not only used for specified or illustrated combinations of features, but also for basically any combination of claimed or illustrated individual features claimed.
In der Zeichnung zeigt die einzige Figur einen axialen Halbschnitt eines erfindungsgemäßen Turboladers im Bereich des Turbinengehäuses.In The drawing shows the sole figure an axial half section a turbocharger according to the invention in the area of the turbine housing.
