Description
Die Erfindung bezieht sich auf ein Turbogetriebe, insbesondere zum Antrieb von Kraftfahrzeugen, mit unabhängig vom Getriebe und höher als dieses liegendem Vorratsbehälter, in 5" dessen beide Leitungen je eine besondere Pumpe eingeschaltet ist.The invention relates to a turbo transmission, in particular for driving motor vehicles, with independent of the gear and higher than this lying storage container, in 5 "whose two lines each have a special pump switched on.
Es ist bekannt, Turbogetriebe mit einem unterhalb der Kreisläufe liegenden Vorratsbehälter zu versehen, der die Arbeitsflüssigkeit enthält und aus welchem diese mit Hilfe einer Zahnrad- oder Zentrifugalpumpe in einen der Kreisläufe gefördert wird, um beim Entleeren des Kreislaufes durch Wirkung der Schwerkraft in denselben Behälter zurückzufließen. It is known to have turbo transmissions with a storage tank located below the circuits to be provided, which contains the working fluid and from which this with the help a gear or centrifugal pump is conveyed into one of the circuits in order to empty it of the circuit to flow back into the same container by the action of gravity.
Bei über den Kreisläufen liegendem Vorratsbehälter muß die Arbeitsflüssigkeit durch eine besondere Pumpe immer wieder in den Behälter hochgedrückt werden. Das von den Kreisläufen austretende öl ist aber sehr schaumig, so daß die bisher allgemein übliche Verwendung einer normalen Kreiselpumpe zur Förderung dieses Öl-Luft-Gemisches in den Behälter Schwierigkeiten bereitet und den Betrieb unwirtschaftlich gestaltet. Die normale Zentrifugalpumpe muß für solche Fälle außerordentlich groß ausgeführt werden und verlangt dann einen hohen Leistungsverbrauch, der im Vergleich zur gesamten Leistung des Landfahrzeuges erheblich ins Gewicht fällt und dadurch die Wirtschaftlichkeit dieser Kraftübe'rtragungseinrichtung in Frage stellt.If the storage tank is located above the circuits, the working fluid must pass through a special pump has to be pushed up into the container over and over again. That of the However, the oil escaping from circuits is very foamy, so that the previously common Use of a normal centrifugal pump to convey this oil-air mixture in the container causes difficulties and makes the operation uneconomical. The normal one Centrifugal pump must be made extremely large for such cases and then requires a high power consumption compared to the total power of the land vehicle is significant and thus the economy this Kraftübe'rtragungseinrichtung questions.
Zur Rückförderung solchen mit Schaum durchsetzten Öles in den Vorratsbehälter soll erfindungsgemäß eine Zahnradpumpe verwen-' det werden, da sie als volumetrische Maschine arbeitet. Die Zahnradpumpe kann im Vergleich zu der bisher für solche Zwecke ge^ bräuchlichen Kreiselpumpe sehr klein gehalten werden und benötigt zur Förderung derselben ölmenge bei derselben Förderhöhe nur etwa io°/o der Leistung der Kreiselpumpe. To return such oil interspersed with foam to the storage container According to the invention, a gear pump can be used, since it is used as a volumetric machine is working. The gear pump can ge ^ compared to the previous one for such purposes Conventional centrifugal pumps are kept very small and required to deliver the same amount of oil at the same head only about 10 per cent of the power of the centrifugal pump.
Vorteilhaft ist es, die Rückförderpumpe für die Arbeits- bzw. Leckfiüsigkeit am tiefsten Punkte des Gehäuses anzuordnen.It is advantageous to have the return pump for the working or leakage fluid deepest To arrange points of the housing.
Weiterhin ist es vorteilhaft, die Pumpe zum Füllen des Getriebes mit der Rückförderpumpe für die Arbeitsflüssigkeit in an sich bekannter Weise auf eine gemeinsame Welle zu setzen. Bei Anordnung von zwei Kreisläufen können dann zweckmäßig die auf der gleichen Welle sitzende Rückf Order-und Füllpumpe im Räume zwischen den beiden Kreislaufen angeordnet werden.It is also advantageous to use the return pump to fill the gearbox to set for the working fluid in a known manner on a common shaft. When arranging two circuits The return and filling pump, which is seated on the same shaft, can then expediently be used be arranged in the spaces between the two circles.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing.
In dem Gehäuse G sind die auf der Primärwelle A und der Sekundärwelle B sitzenden Lauf räder α1 bzw. b1 angeordnet. Von der Primärwelle A werden die Pumpen C und D über den Kegelradantrieb F und die gemeinsame" Welle/1 angetrieben. Die am tiefsten Punkt des Gehäuses liegende Zahnradpumpe C 6S dient zur Rückförderung der Arbeits- und Leckflüssigkeit in den höher gelegenen Vorratsbehälter E, während die Pumpe D die Füllung der Kreisläufe besorgt.In the housing G , the running wheels α 1 and b 1, which are seated on the primary shaft A and the secondary shaft B , are arranged. From the primary shaft A pump C and D via the bevel gear F and the joint "shaft / 1 to be driven. The lying at the lowest point of the housing gear pump C 6 S serves for pumping the working and leak fluid into the higher storage tank E while pump D takes care of the filling of the circuits.
