Abstract
Flüssigkeit gekühlte Brennkraftmaschine mit einem ersten Abgasturbolader, dessen Turbinenrad in einem Abgasstrang der Brennkraftmaschine angeordnet ist, wobei das Turbinenrad über eine erste Welle eingangsseitig mit einem Getriebe in Wirkverbindung ist und das Getriebe ausgangsseitig über eine zweite Welle mit einer Fluidpumpe in Wirkverbindung ist, wobei in dem Abgasstrang ein Turbinenrad eines zweiten Abgasturboladers angeordnet ist, der über eine dritte Welle mit dem Getriebe in Wirkverbindung ist, wobei das Getriebe ein Umlaufrädergetriebe ist.
Mit der erfindungsgemäßen Ausgestaltung werden Getriebegeräusche vermieden.
Liquid cooled internal combustion engine having a first exhaust gas turbocharger, the turbine wheel is arranged in an exhaust line of the internal combustion engine, wherein the turbine via a first shaft input side is in operative connection with a transmission and the transmission is on the output side via a second shaft with a fluid pump in operative connection, wherein in the Exhaust line, a turbine of a second exhaust gas turbocharger is arranged, which is connected via a third shaft to the transmission in operative connection, wherein the transmission is a planetary gear.
With the embodiment of the invention transmission noises are avoided.
Description
Die Erfindung betrifft eine Flüssigkeit gekühlte Brennkraftmaschine mit einem Abgasturbolader mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a liquid-cooled internal combustion engine having an exhaust gas turbocharger with the features of the preamble of
Zum technischen Umfeld wird beispielsweise auf die Deutsche Gebrauchsmusterschrift

Nachteilig an der bekannten Ausgestaltung ist der indirekte Antrieb der Nebenaggregate.A disadvantage of the known embodiment is the indirect drive of the ancillaries.
Aufgabe der vorliegenden Erfindung ist es, oben genannten Nachteil zu vermeiden.Object of the present invention is to avoid the above drawback.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is solved by the features in the characterizing part of
Erfindungsgemäß wird eine praktische Umsetzung einer Kühlmittelpumpe mit Antrieb über eine Abgasturbine beschrieben. Aufgrund der Drehzahldifferenz zwischen der Kühlmittelpumpe (ca. 1000 bis 10000 1/min) und dem Abgasturbolader (je nach Auslegung ca. 10000 bis 200000 1/min) muss ein Getriebe eingesetzt werden. Die hohe Übersetzung kann dabei ein Problem darstellen (Geräusche, Reibung, etc.), weshalb vorgeschlagen wird, ein Umlaufrädergetriebe mit zwei Abgasturbinen einzusetzen, die so dimensioniert sind, dass die Kühlmittelpumpe über die benötigte Drehzahldifferenz angetrieben wird.According to the invention, a practical implementation of a coolant pump with drive via an exhaust gas turbine is described. Due to the speed difference between the coolant pump (about 1000 to 10000 rpm) and the turbocharger (depending on the design about 10,000 to 200,000 rpm), a gearbox must be used. The high ratio can be a problem (noise, friction, etc.), which is why it is proposed to use a planetary gear with two exhaust gas turbines, which are dimensioned so that the coolant pump is driven by the required speed difference.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.
So weist das Getriebe gemäß Patentanspruch 2 eine Untersetzung von ca. 10 zu 1 bis 20 zu 1 auf.Thus, the transmission according to claim 2, a reduction of about 10 to 1 to 20 to 1 on.
In einer Weiterbildung der Erfindung ist zumindest ein Turbinengehäuse der Abgasturbolader von dem geförderten Fluid kühlbar, wobei die Fluidpumpe gemäß Patentanspruch 4 bevorzugt eine Kühlmittelpumpe ist.In one development of the invention, at least one turbine housing of the exhaust gas turbocharger can be cooled by the conveyed fluid, wherein the fluid pump according to
Mit der Ausgestaltung gemäß Patentanspruch 5 sind die Turbinenräder des ersten Abgasturboladers und des zweiten Abgasturboladers beliebig zu- und abschaltbar .With the embodiment according to
Im Folgenden ist die Erfindung anhand einer einzigen Zeichnung näher dargestellt.

Erfindungsgemäß ist in dem Abgasstrang der Brennkraftmaschine ein Turbinenrad
Umlaufrädergetriebe sind Zahnradgetriebe, die neben gehäusefesten Wellen auch Achsen besitzen, die auf Kreisbahnen im Gehäuse umlaufen. In vielen Ausführungen sind die umlaufenden Achsen parallel zu den gehäusefesten Wellen, weshalb Umlaufrädergetriebe meist Planetengetriebe oder auch Planetenrädergetriebe genannt werden. Die auf den umlaufenden Achsen drehbaren Zahnräder, auch Planetenräder genannt umkreisen ein zentrales Zahnrad, auch Sonnenrad genannt. Umlaufrädergetriebe sind sehr kompakt bauende Getriebe.Planetary gear are gear transmissions that have next to fixed shafts and axles that rotate on circular paths in the housing. In many embodiments, the rotating axles are parallel to the shaft fixed to the housing, which is why epicyclic gearboxes are usually called planetary gear or planetary gear. The rotatable on the rotating axes gears, also called planetary gears orbiting a central gear, also called sun gear. Epicyclic gears are very compact gearboxes.
In der vorliegenden Ausführung wird das Umlaufrädergetriebe im sogenannten 3-Wellen-Betrieb betrieben. Es arbeitet somit als Umlenkgetriebe oder Verteilergetriebe. Bevorzugt hat das Getriebe
In einer Weiterbildung der Erfindung ist zumindest ein Turbinengehäuse der Abgasturbolader von dem Fluid kühlbar, wobei es sich bei dem Fluid vorzugsweise um ein Kühlmittel der Brennkraftmaschine handelt. Dementsprechend ist die Fluidpumpe
