Die Erfindung bezieht sich auf eine Antriebsanordnung für Nebenaggregate von Brennkraftmaschinen der Bauart nach dem Oberbegriff des Anspruches 1. Bei der Brennkraftmaschine nach der DE-OS 2922695 wird die Schmieröl-Zahnradpumpe über ein Untersetzungsgetriebe von einer mit Kurbelwellendrehzahl drehenden Nebenantriebswelle angetrieben. Das größere Zahnrad des Untersetzungsgetriebes ist dabei auf der gemeinsamen Welle der Pumpen angeordnet, die das treibende Pumpenrad der Schmieröl-Zahnradpumpe und das Pumpenlaufrad der Kühlmittelpumpe trägt. Das Untersetzungsgetriebe benötigt Reibleistung, Raum im Gehäuse der Brennkraftmaschine und erhöht das Gewicht und den Fertigungsaufwand.The invention relates to a drive arrangement for auxiliary units of internal combustion engines of the type according to the preamble of claim 1. In the internal combustion engine according to DE-OS 2922695, the lubricating oil gear pump is driven via a reduction gear by a PTO shaft rotating at crankshaft speed. The larger gear of the reduction gear is arranged on the common shaft of the pumps, which carries the driving pump wheel of the lubricating oil gear pump and the pump impeller of the coolant pump. The reduction gear requires friction, space in the housing of the internal combustion engine and increases the weight and the manufacturing effort.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Antriebsanordnung nach dem Oberbegriff des Anspruches 1, die Antriebsverbindung für die Schmieröl-Zahnradpumpe und die Kühlmittelpumpe unter Beibehaltung einer Untersetzung für die Kühlmittelpumpe raumsparend, einfach sowie gewichts- und kostengünstig zu gestalten.The invention is based on the object, in a drive arrangement according to the preamble of claim 1, to design the drive connection for the lubricating oil gear pump and the coolant pump while maintaining a reduction for the coolant pump in a space-saving, simple and weight-saving and cost-effective manner.

Diese Aufgabe löst die Erfindung durch die kennzeichnenden Merkmale des Anspruches 1. Durch die erfindungsgemäße Ausbildung wird eine sehr kompakte Antriebsverbindung für die Schmieröl-Zahnradpumpe und die Kühlmittelpumpe erreicht.The invention solves this problem by the characterizing features of claim 1. The design according to the invention achieves a very compact drive connection for the lubricating oil gear pump and the coolant pump.

In den Ansprüchen 2 und 3 sind Ausführungsformen und Weiterbildungen der Erfindung gekennzeichnet. Durch die Merkmale des Anspruches 2 wird eine vormontierbare Pumpeneinheit gebildet, die einfach am Gehäuse einer Brennkraftmaschine befestigbar ist und eine einfache Bearbeitung der Anschlußflächen am Gehäuse der Brennkraftmaschine und am Pumpengehäuse ermöglicht. Anspruch 3 nutzt den durch den axialen Raumbedarf der Dichtung zwischen Schmieröl- und Kühlmittelpumpe erforderlichen Bauraum für die raumsparende Anordnung des Saugraumes der Kühlmittelpumpe.Embodiments and developments of the invention are characterized in claims 2 and 3. The features of claim 2 form a preassembled pump unit that can be easily attached to the housing of an internal combustion engine and enables simple machining of the connection surfaces on the housing of the internal combustion engine and on the pump housing. Claim 3 uses the space required by the axial space requirement of the seal between the lubricating oil and coolant pump for the space-saving arrangement of the suction space of the coolant pump.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt einen Längsschnitt einer Schmieröl-Zahnradpumpe und einer Kühlmittelpumpe einschließlich ihrer Antriebsverbindung für eine Brennkraftmaschine.In the drawing, an embodiment of the invention is shown. It shows a longitudinal section of a lubricating oil gear pump and a coolant pump including their drive connection for an internal combustion engine.

An einer Anschlußfläche 1 eines Gehäuseteiles 2 einer nicht weiter dargestellten Brennkraftmaschine ist ein Pumpengehäuse 3 mit seiner Anbaufläche 4 befestigt. Das Pumpengehäuse 3 enthält in seinem dem Gehäuseteil 2 zugewandten Abschnitt in einer Vertiefung 5 Pumpenräder 6 und 7 einer Schmieröl-Zahnradpumpe 8 und im gegenüberliegenden Abschnitt eine Kühlmittelpumpe 9 mit einem Pumpenlaufrad 10. Den Abschluß bildet ein Gehäusedeckel 11. Das treibende Pumpenrad 6 der Schmieröl-Zahnradpumpe 8 weist eine kleinere Zähnezahl auf als das angetriebene Pumpenrad 7. Dadurch bilden die Pumpenräder 6 und 7 ein Untersetzungsgetriebe für die Kühlmittelpumpe 9. Das treibende Pumpenrad 6 ist auf einer im Pumpengehäuse 3 gelagerten Welle 12 drehfest befestigt. Die Welle 12 ist koaxial zu einer Nebenantriebswelle 13 der Brennkraftmaschine angeordnet und mit der Nebenantriebswelle 13 über eine Steckkupplung 14 antriebsverbunden.A pump housing 3 is attached with its mounting surface 4 to a connection surface 1 of a housing part 2 of an internal combustion engine (not shown further). The pump housing 3, in its section facing the housing part 2, contains 5 pump wheels 6 and 7 of a lubricating oil gear pump 8 in a recess and in the opposite section a coolant pump 9 with a pump impeller 10. The end is formed by a housing cover 11. The driving pump wheel 6 of the lubricating oil Gear pump 8 has a smaller number of teeth than the driven pump wheel 7. As a result, the pump wheels 6 and 7 form a reduction gear for the coolant pump 9. The driving pump wheel 6 is fixed in a rotationally fixed manner on a shaft 12 mounted in the pump housing 3. The shaft 12 is arranged coaxially to a power take-off shaft 13 of the internal combustion engine and drive-connected to the power take-off shaft 13 via a plug-in coupling 14.

Das getriebene Pumpenrad 7 der Schmieröl-Zahnradpumpe 8 und das Pumpenlaufrad 10 der Kühlmittelpumpe 9 sind auf einer gemeinsamen Pumpenwelle 15 angeordnet. Die Pumpenwelle 15 ist im Pumpengehäuse 3 und im Gehäuseteil 2 gelagert. Zwischen dem Pumpenrad 7 und dem Pumpenlaufrad 10 sind eine erste Dichtung 16, ein Leck-Ableitraum 17 und eine zweite Dichtung 18 angeordnet. Vom Leck-Ableitraum 17 führt ein Leck-Ableitkanal 19 ins Freie. Ein etwa ringförmiger Saugraum 20 der Kühlmittelpumpe 9 umgibt mit Abstand die Dichtungen 16 und 18 und den Ringraum 17 und ist in seiner axialen Ausdehnung schraubenlinienförmig gestaltet.The driven pump wheel 7 of the lubricating oil gear pump 8 and the pump impeller 10 of the coolant pump 9 are arranged on a common pump shaft 15. The pump shaft 15 is mounted in the pump housing 3 and in the housing part 2. A first seal 16, a leak discharge space 17 and a second seal 18 are arranged between the pump wheel 7 and the pump impeller 10. A leak discharge channel 19 leads from the leak discharge space 17 into the open. An approximately annular suction space 20 of the coolant pump 9 surrounds the seals 16 and 18 and the annular space 17 at a distance and is designed to be helical in its axial extent.

Durch die koaxiale Anordnung des treibenden Pumpenrades 6 zur Nebenantriebswelle 13 und die als Steckkupplung 14 ausgebildete Antriebsverbindung mit der Nebenantriebswelle 13 können die Schmieröl-Zahnradpumpe 8 und die Kühlmittelpumpe 9 als gemeinsame Pumpeneinheit vormontiert werden, so daß der Zusammenbau mit dem Gehäuseteil 2 vereinfacht ist. Die Anordnung der Pumpenräder 6 und 7 der Schmieröl-Zahnradpumpe 8 in einer Vertiefung 5 des Pumpengehäuses 3 vereinfacht die Bearbeitung der Anschlußfläche 1 am Gehäuseteil 2 und der Anbaufläche 4 des Pumpengehäuses 3. Der Saugraum 20 der Kühlmittelpumpe 9 ist raumsparend zwischen dem getriebenen Pumpenrad 7 der Schmieröl-Zahnradpumpe 8 und dem Pumpenlaufrad 10 der Kühlmittelpumpe 9 angeordnet und nutzt dabei den radial außen liegenden Teil des Zwischenraumes zwischen diesen beiden Rädern, der aufgrund der Dichtungen 16 und 18 und des Leck-Ableitraumes 17 vorgesehen werden muß.Due to the coaxial arrangement of the driving pump wheel 6 to the auxiliary drive shaft 13 and the drive connection designed as a plug-in coupling 14 with the auxiliary drive shaft 13, the lubricating oil gear pump 8 and the coolant pump 9 can be preassembled as a common pump unit, so that the assembly with the housing part 2 is simplified. The arrangement of the pump wheels 6 and 7 of the lubricating oil gear pump 8 in a recess 5 of the pump housing 3 simplifies the machining of the connection surface 1 on the housing part 2 and the mounting surface 4 of the pump housing 3. The suction chamber 20 of the coolant pump 9 saves space between the driven pump wheel 7 Lubricating oil gear pump 8 and the pump impeller 10 of the coolant pump 9 arranged and uses the radially outer part of the space between these two wheels, which must be provided due to the seals 16 and 18 and the leakage discharge space 17.

Durch Nutzung der Pumpenräder 6 und 7 der Schmieröl-Zahnradpumpe 8 als Untersetzungsgetriebe für die Kühlmittelpumpe 9 wird eine raumsparende Antriebsanordnung für eine Pumpeneinheit von Brennkraftmaschinen mit geringem Gewichts- und Kostenaufwand erreicht.By using the pump wheels 6 and 7 of the lubricating oil gear pump 8 as a reduction gear for the coolant pump 9, a space-saving drive arrangement for a pump unit of internal combustion engines is achieved with little weight and expense.
