Abstract
Description
Die Erfindung bezieht sich auf Abgasturbolader mit einem ein Verdichterteil sowie ein Turbinenteil umfassenden Rotor.The The invention relates to exhaust gas turbochargers with a compressor part and a rotor comprising a turbine part.
Derartige Abgasturbolader werden heute in vielen Serienfahrzeugen zur Leistungssteigerung der Motoren eingesetzt. Im Hinblick auf ein gutes Betriebsverhalten des Abgasturboladers sind leichte, trägheitsarme Rotoren besonders erwünscht. Die leichte Bauweise bringt jedoch die Gefahr vorzeitiger Materialermüdungen, für die insbesondere Wechselbelastungen des Rotors verantwortlich sind, mit sich.such Exhaust gas turbochargers are today in many production vehicles to increase performance the motors used. With regard to a good operating behavior the exhaust gas turbocharger are lightweight, low-inertia rotors particularly he wishes. The lightweight design, however, brings the risk of premature material fatigue, for the especially alternating loads of the rotor are responsible, with himself.
Deshalb ist es Aufgabe der Erfindung, einen Abgasturbolader mit einer Bauart zu schaffen, die zu besonders geringen Wechselbeanspruchungen des Rotors führt.Therefore It is an object of the invention to provide an exhaust gas turbocharger of a type to create, which leads to particularly low alternating stresses of the rotor leads.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Rotor mit zu einer Horizontalebene geneigter Achse angeordnet ist, wobei der Neigungswinkel zwischen etwa 45° und 90° und in bevorzugter Weise bei etwa 80° liegt.These Task is inventively characterized solved, that the rotor is arranged with an axis inclined to a horizontal plane is, wherein the inclination angle between about 45 ° and 90 °, and preferably at about 80 °.
Die Erfindung beruht auf dem allgemeinen Gedanken, die bisherige Standardbauweise, bei der ein Abgasturbolader mit horizontaler Rotorachse vorgesehen ist, zu verlassen und zu einer Bauweise mit angenähert vertikaler Rotorachse überzugehen. Hierbei wird die Erkenntnis ausgenutzt, dass sich die bisherige Standardbauweise von Abgasturboladern an die Bauweise von Flugzeugantrieben anlehnt, bei denen ein horizontaler Schub benötigt wird, und wobei sich das Flugzeug überwiegend in horizontaler Richtung bewegen soll und die verdichterseitige Einlassströmung sowie die turbinenseitige Auslassströmung horizontal ausgerichtet sind und bei horizontaler Rotorachse eine optimale Durchströmung des Triebwerks gewährleistet werden kann. Bei einem Abgasturbolader dagegen sind keine mit einer horizontalen Rotorachse verbundenen Vorteile ersichtlich. Andererseits ergeben sich bei einer horizontalen Rotorachse erhebliche Wechselbeanspruchungen an umlaufenden Rotorteilen, weil diese nicht nur von Zentrifugalkräften sondern auch von Gravitationskräften beansprucht werden, und zwar in zur Umlaufrichtung wechselnden Richtungen. Diese Wechselbeanspruchungen sind insbesondere bei unvermeidlichen Unwuchten des Rotors aufgrund von Fertigungstoleranzen beachtlich.The Invention is based on the general idea, the previous standard construction, in which provided an exhaust gas turbocharger with horizontal rotor axis is to leave and to a construction with approximately vertical Rotor axis to pass. in this connection the knowledge is exploited that the previous standard construction of exhaust gas turbochargers to the design of aircraft drives, where a horizontal thrust is needed, and where the Airplane predominantly to move in the horizontal direction and the compressor side inlet flow and the turbine-side outlet flow aligned horizontally are and with horizontal rotor axis an optimal flow through the engine guaranteed can be. In an exhaust gas turbocharger on the other hand are none with a horizontal rotor axis benefits apparent. on the other hand arise in a horizontal rotor axis significant alternating stresses rotating rotor parts, because these not only by centrifugal forces but also from gravitational forces be claimed, in the direction of rotation changing directions. These alternating stresses are particularly unavoidable Imbalance of the rotor due to manufacturing tolerances considerable.
Theoretisch müsste ein Rotor mit vertikaler Rotorachse hinsichtlich der vorgenannten Wechselbeanspruchungen optimal sein. Jedoch ist gemäß einer besonders bevorzugten Ausführungsform der Erfindung vorgesehen, dass die Neigung der Rotorachse relativ zu einer Horizontalebene bei maximal etwa 80° liegt. Damit wird eine gewisse Abweichung gegenüber der Vertikalrichtung vorgegeben und der Vorteil erreicht, dass der Rotor in Ruhelage von Gravitationskräften in eine bevorzugte Ausgangslage gedrängt wird. Dies bietet zusätzliche Vorteile bei der Konzeption der Rotorlager.Theoretically should a rotor with a vertical rotor axis with respect to the aforementioned Alternating stresses are optimal. However, according to one particularly preferred embodiment the invention provided that the inclination of the rotor axis relative to a horizontal plane at a maximum of about 80 °. This will be a certain Deviation from the vertical direction predetermined and achieved the advantage that the Rotor in rest position of gravitational forces in a preferred starting position packed becomes. This offers additional Advantages in designing the rotor bearings.
Grundsätzlich wird mit der Erfindung hinsichtlich der Rotorlager der Vorteil geboten, dass nur verminderte radiale Tragkräfte an den Lagern gewährleistet sein müssen und dementsprechend mit der Erfindung die Möglichkeit geschaffen wird, „unkonventionelle” Anordnungen mit relativ geringen Tragkräften für die Radiallagerung des Motors vorzusehen.Basically with the invention with regard to the rotor bearings offered the advantage that only reduced radial loads on the bearings ensured have to be and accordingly the invention provides the possibility of "unconventional" arrangements with relatively low load capacities for the Provide radial bearing of the engine.
So eröffnet die Erfindung die Möglichkeit, berührungsfreie Lageranordnungen wie z. B. Magnetlagerungen oder Luftlagerungen vorzusehen.So open the invention the possibility noncontact Bearing arrangements such. B. magnetic bearings or air bearings provided.
Stattdessen können auch „unkonventionelle” Gleit- oder Wälzlager mit Lagerteilen aus Kunststoff vorgesehen werden.Instead can also "unconventional" sliding or rolling bearings be provided with bearing parts made of plastic.
Insbesondere können bei der Erfindung schmierstofffreie Lager eingesetzt werden, so dass Betriebsphasen mit stark erhöhtem Verschleiß aufgrund der Zähflüssigkeit von Schmierstoffen bei niedriger Temperatur vermieden werden.Especially can in the invention, lubricant-free bearings are used, so that operating phases with greatly increased wear due to viscosity of lubricants at low temperature can be avoided.
Im Übrigen wird hinsichtlich bevorzugter Ausführungsformen der Erfindung auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der eine besonders bevorzugte Ausführungsform der Erfindung näher beschrieben wird.Incidentally, will in terms of preferred embodiments the invention to the claims and the following explanation referred to the drawing, based on a particularly preferred embodiment closer to the invention is described.
Schutz wird nicht nur für ausdrücklich angegebene oder dargestellte Merkmalskombinationen sondern auch für prinzipielle beliebige Kombinationen der angegebenen oder dargestellten Einzelmerkmale beansprucht.protection will not only for expressly indicated or illustrated feature combinations but also for principled any combination of the specified or illustrated individual features claimed.
