Abstract
Description
Die Erfindung betrifft einen Abgasturbolader mit variabler Turbinengeometrie einer Brennkraftmaschine, insbesondere eines Kraftfahrzeuges, mit an einem Leitschaufelträger schwenkbar angeordneten Leitschaufeln einer Turbine, denen jeweils ein Verstellhebel zugeordnet ist, und mit einem Verstellring, welcher mit den Verstellhebeln zusammen wirkt und durch Drehung relativ zum Leitschaufelträger eine Winkelstellung der Leitschaufeln relativ zu einer Strömungsrichtung kollektiv für alle Leitschaufeln verstellt, wobei der Verstellring an seiner radialen Innenfläche in mehreren, in Umfangsrichtung voneinander beabstandeten und bezüglich des Verstellringes radial innen liegend angeordneten Gleitlagern geführt ist, die am Leitschaufelträger angeordnet sind und eine Gleitlagerfläche sowie beidseitig dieser angeordnete seitliche Führungselemente für den Verstellring aufweisen, gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an exhaust gas turbocharger with variable turbine geometry an internal combustion engine, in particular a motor vehicle, with on a vane carrier pivotally arranged vanes of a turbine, each of which an adjusting lever is assigned, and with an adjusting ring, which interacts with the adjusting levers and relative rotation to the vane carrier an angular position of the vanes relative to a flow direction collectively for adjusted all the vanes, wherein the adjusting ring at its radial palm in a plurality, circumferentially spaced from each other and with respect to the Adjusting ring is guided radially inside lying plain bearings, which on the vane carrier are arranged and a sliding bearing surface and both sides of this arranged lateral guide elements for the Have adjusting ring, according to the preamble of claim 1
Der Erfindung liegt die Aufgabe zugrunde, eine Montage eines Abgasturboladers zu vereinfachen.Of the Invention is based on the object, a mounting of an exhaust gas turbocharger to simplify.
Diese Aufgabe wird erfindungsgemäß durch einen Abgasturbolader der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.These The object is achieved by a Exhaust gas turbocharger of the o.g. Type with the characterized in claim 1 Characteristics solved. Advantageous embodiments of the invention are in the other claims described.
Dazu ist es bei einem Abgasturbolader der o.g. Art erfindungsgemäß vorgesehen, dass wenigstens eines der seitlichen Führungselemente für den Verstellring in Umfangsrichtung mit wenigstens einem ausgesparten Bereich derart ausgebildet ist, dass in dem ausgesparten Bereich das die Gleitlagerfläche ausbildende Bauteil des Gleitlagers das seitliche Führungselement in radialer Richtung nach außen überragt oder zumindest eben mit dem seitlichen Führungselement abschließt.To it is in an exhaust gas turbocharger the o.g. Art provided according to the invention, that at least one of the lateral guide elements for the adjusting ring in the circumferential direction with at least one recessed area such is formed so that in the recessed area forming the sliding bearing surface Component of the sliding bearing, the lateral guide element in the radial direction surmounted to the outside or at least just with the lateral guide element closes.
Dies hat den Vorteil, dass in dem ausgesparten Beeich keine seitliche Führung für den Verstellring vorhanden ist, so dass zu Montage zuerst die Gleitlager mit radial nach außen weisenden ausgesparten Bereichen in den Leitschaufelträger gesteckt und anschließend der Verstellring über die ausgesparten Beeiche hinweg auf die Gleitlagerflächen der Gleitlager bzw. auf das die Gleitlagerfläche ausbildende Bauteil des Gleitlagers aufgeschoben werden kann. Eine seitliche Führung für den Verstellring im Gleitlager wird dann durch einfaches Verdrehen des Gleitlagers hergestellt, so dass der ausgesparte Bereich radial nach innen weist und sich keine Aussparung der seitlichen Führung mehr im Bereich des Verstellringes befindet. Ein sonst notwendiges gleichzeitiges Montieren von Verstellring und Gleitlagern, welches aufwändig und zeitintensiv ist, kann damit entfallen. Mit anderen Worten vereinfacht sich die Montage, da alle Bauteile nacheinander auf den Leitschaufelträger aufgesteckt und anschließend verpresst werden können.This has the advantage that in the recessed Beeich no lateral guide for the Adjusting ring is present, so to assembly first the plain bearings with radially outward inserted recessed areas in the vane support and plugged subsequently the adjusting ring over the recessed Beeiche away on the sliding bearing surfaces of the plain bearings or on the sliding bearing surface training component of the sliding bearing can be postponed. A lateral guidance for the Adjusting ring in plain bearing is then by simply turning the plain bearing made so that the recessed area facing radially inward and no recess of the lateral guide more in the region of the adjusting ring located. An otherwise necessary simultaneous mounting of adjusting ring and plain bearings, which is expensive and time-consuming, can be dispensed with. In other words simplified the assembly, as all components successively mounted on the guide vane and subsequently can be pressed.
In einer bevorzugten Ausführungsform sind die seitlichen Führungselemente als Scheiben und die ausgesparten Bereiche als asymmetrische Bereiche wenigstens einer der Scheiben eines Gleitlagers ausgebildet. Hierbei ist der ausgesparte Bereich bevorzugt als ein abgeschnittener Bereich der Scheibe mit einer Schnittebene ausgebildet ist, welche den Außenumfang der Gleitlagerfläche tangiert oder von einer Mittelachse des Gleitlagers in radialer Richtung einen Abstand aufweist welcher kleiner oder gleich dem Radius der Gleitlagerfläche ist.In a preferred embodiment are the lateral guide elements as slices and the recessed areas as asymmetric areas formed at least one of the discs of a sliding bearing. in this connection For example, the recessed area is preferable as a cut-off area the disc is formed with a sectional plane which the outer circumference the sliding bearing surface tangent or from a central axis of the plain bearing in radial Direction has a distance which is less than or equal to Radius of the sliding bearing surface is.
Zweckmäßigerweise weist wenigstens dasjenige seitliche Führungselement einen ausgesparten Bereich auf, welches an einem von dem Leitschaufelträger abgewandten Ende des Gleitlager angeordnet ist.Conveniently, at least that lateral guide element has a recessed Area on which facing away from the vane carrier on one End of the sliding bearing is arranged.
