Abstract
Description
Die Erfindung betrifft das Gebiet der Abgasturbolader.The The invention relates to the field of exhaust gas turbochargers.
Abgasturbolader sind bei modernen Kraftfahrzeugen unverzichtbar. Sie umfassen als wichtigste Bauteile eine Turbine und einen Verdichter. Diese beiden Bauteile sitzen im Allgemeinen auf ein- und derselben Welle oder stehen zumindest in Triebverbindung miteinander. Der Turbine wird das Abgas einer Brennkraftmaschine zugeleitet. Das Abgas treibt die Turbine an. Die Turbine treibt ihrerseits den Verdichter an. Dieser saugt Luft aus der Umgebung an und verdichtet diese. Die verdichtete Luft wird sodann für die Verbrennung in der Brennkraftmaschine ausgenutzt. Abgasturbolader haben den Zweck, die Abgasemissionen zu verringern sowie den Wirkungsgrad der Brennkraftmaschine und deren Drehmoment zu erhöhen. Sie haben außerdem eine wichtige Funktion bezüglich der Wirkung des Katalysators.turbocharger are indispensable in modern motor vehicles. They include as most important components a turbine and a compressor. These two Components generally sit on one and the same shaft or are at least in drive connection with each other. The turbine will the exhaust gas fed to an internal combustion engine. The exhaust gas drives the Turbine on. The turbine in turn drives the compressor. This sucks air from the environment and compresses it. The condensed Air is then used for combustion in the internal combustion engine. Exhaust gas turbochargers have the purpose of reducing exhaust emissions and the efficiency of the internal combustion engine and its torque to increase. They also have an important function concerning the effect of the catalyst.
Die vorliegende Erfindung befasst sich mit der genannten Welle und deren Lagerung. Die Lagerung ist von entscheidender Bedeutung für den gesamten Abgasturbolader, insbesondere für dessen Lebensdauer sowie für dessen Geräuschentwicklung.The The present invention is concerned with said shaft and its Storage. Storage is crucial for the entire exhaust gas turbocharger, in particular for its life as well as for its noise development.
Es
sind zahlreiche Arten von Lagerungen bekannt geworden.
Der Erfindung liegt die Aufgabe zugrunde, eine Lagerung für einen Abgasturbolader derart zu gestalten, dass der Oil-Whip-Effekt minimiert wird, und damit auch die Geräuschentwicklung sowie der Verschleiß. Gleichzeitig sollen die Herstellungskosten minimiert werden.Of the Invention is the object of a storage for to design an exhaust gas turbocharger such that the oil whip effect is minimized, and thus the noise as well as the wear. At the same time, the production costs be minimized.
Diese Aufgabe wird mit einem Abgasturbolader gelöst, der die Merkmale von Anspruch 1 aufweist.These Task is solved with an exhaust gas turbocharger, the Features of claim 1.
Die Lagerbuchse ist demgemäß in einem Lagergehäuse gelagert. Sie ist mit Bohrungen versehen, die derart angeordnet werden, dass eine definierte Unwucht entsteht. Durch diese definierte Unwucht der mitrotierenden Lagerbuchse oder Lagerbuchsen wird die Ausprägung der zweiten subharmonischen Schwingung gedämpft. Die Lagerbuchse kann auf der Welle frei drehbar gelagert sein. Sie kann aber auch drehfest mit der Welle verbunden sein.The Bushing is accordingly in a bearing housing stored. It is provided with holes arranged in such a way be that a defined imbalance arises. Defined by this Imbalance of co-rotating bushing or bushings is the Expression of the second subharmonic vibration dampened. The bearing bush can be freely rotatably mounted on the shaft. she can but also rotatably connected to the shaft.
Statt einer einzigen Lagerbuchse können auch zwei oder mehrere Lagerbuchsen vorgesehen werden.Instead of A single bearing bush can also have two or more Bushings are provided.
Die genannten Bohrungen können an jeglicher Stelle in die betreffende Lagerbuchse eingebracht werden, beispielsweise von der Stirnseite her oder vom Außenumfang her. Die Bohrungen können parallel oder senkrecht zur Drehachse der Welle verlaufen, jedoch auch unter einem Winkel hierzu. Auch können Ölversorgungsbohrungen im Sinne der Erfindung ausgenutzt werden, indem man einige hiervon weglässt oder verkleinert oder an einem anderen Ort anordnet.The mentioned holes can be anywhere in the relevant Bearing bush are introduced, for example, from the front side from or from the outer circumference. The holes can be parallel or perpendicular to the axis of rotation of the shaft, but also below an angle to it. Also can oil supply holes be exploited in the sense of the invention by omitting some of these or reduced or ordered at another location.
Die Erfindung zeichnet sich durch die Wahl von Bohrungen durch große Einfachheit und damit geringe Herstellungskosten aus. Das Maß der Unwucht lässt sich feinfühlig dosieren, beispielsweise durch Wahl des Bohrungsdurchmessers oder der Bohrungstiefe.The Invention is characterized by the choice of holes through large Simplicity and thus low production costs. The measure of Imbalance can be sensitively metered, for example by Choice of bore diameter or hole depth.
Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im Einzelnen folgendes dargestellt:The The invention is explained in more detail with reference to the drawing. The following is shown in detail:
