Eine Brennkraftmaschine weist eine Antriebsverbindung für Nebenaggregate mit einem Untersetzungsgetriebe für eine Kühlmittelpumpe (22') auf, das durch Pumpenräder (59', 60') einer Schmieröl-Zahnradpumpe gebildet ist.An internal combustion engine has a drive connection for auxiliary units with a reduction gear for a coolant pump (22 '), which is formed by pump wheels (59', 60 ') of a lubricating oil gear pump.

Description

Die Erfindung bezieht sich auf eine Brennkraftmaschine der Bauart nach dem Oberbegriff des Anspruches 1, insbesondere nach Patent ...... (Patentanmeldung P 29 22 695). Bei der Brennkraftmaschine nach dem Hauptpatent 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 den Fertigungsaufwand. Aus Gründen des Pumpenleistungsverhaltens wird die Kühlmittelpumpe meist mit gegenüber der Kurbelwelle herabgesetzter Drehzahl betrieben.The invention relates to an internal combustion engine of the type according to the preamble of claim 1, in particular according to patent ...... (patent application P 29 22 695). In the internal combustion engine according to the main patent, the lubricating oil gear pump is driven by a power take-off shaft rotating at crankshaft speed via a reduction gear. 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 manufacturing effort. For reasons of pump performance, the coolant pump is usually operated at a lower speed than the crankshaft.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Brennkraftmaschine nach dem Oberbegriff des Anspruches 1, die Antriebsverbindung für die Schmieröl-Zahnradpumpe und die Kühlmittelpumpe unter Beibehaltung einer Untersetzung für die Kühlmittelpumpe raumsparend, einfach und kostengünstig zu gestalten.The invention has for its object to make space-saving, simple and inexpensive in an internal combustion engine according to the preamble of claim 1, the drive connection for the lubricating oil gear pump and the coolant pump while maintaining a reduction for the coolant pump.

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 bis 4 sind Ausführungsformen und Weiterbildungen der Erfindung gekennzeichnet. Durch die Merkmale des Anspruches 2 wird eine vormontierbare Pumpen . einheit gebildet, die einfach am Gehäuse einer Brennkraftmaschine befestigbar und von diesem lösbar ist. Die Merkmale des Anspruches 3 vereinfachen die Bearbeitung der Anschlußflächen am Gehäuse der Brennkraftmaschine und am Pumpengehäuse. Anspruch 4 nutzt den durch den axialen Raumbedarf der Dichtung der Kühlmittelpumpe erforderlichen Bauraum für die raumsparende Anordnung des Saugraumes der Kühlmittelpumpe.Embodiments and developments of the invention are characterized in claims 2 to 4. Due to the features of claim 2, a pre-assembled pump. Unit formed, which can be easily attached to and detachable from the housing of an internal combustion engine. The features of claim 3 simplify the machining of the connection surfaces on the housing of the internal combustion engine and on the pump housing. Claim 4 uses the space required by the axial space requirement of the seal of the coolant pump for the space-saving arrangement of the suction space of the coolant pump.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles erläutert. Die Zeichnung zeigt einen vertikalen Längsschnitt einer Schmieröl-Zahnradpumpe und einer Kühlmittelpumpe einschließlich ihrer Antriebsverbindung mit einer Nebenantriebswelle einer nicht weiter dargestellten Brennkraftmaschine.The invention is explained below using an exemplary embodiment shown in the drawing. The drawing shows a vertical longitudinal section of a lubricating oil gear pump and a coolant pump including their drive connection with a power take-off shaft of an internal combustion engine, not shown.

An einer Anschlußfläche 71 eines Gehäuseteiles 6' einer nicht weiter dargestellten Brennkraftmaschine ist ein Pumpengehäuse 72 mit seiner Anbaufläche 73 befestigt. Das Pumpengehäuse 72 enthält in seinem dem Gehäuseteil 6' zugewandten Abschnitt in einer Vertiefung 74 Pumpenräder 59' und 60' einer Schmieröl-Zahnradpumpe und im gegenüberliegenden Abschnitt eine Kühlmittelpume 22' mit einem Pumpenlaufrad 58'. Den Abschluß bildet ein Gehäusedeckel 75. Das treibende Pumpenrad 59' der Schmieröl-Zahnradpumpe weist eine kleinere Zähnezahl auf als das angetriebene Pumpenrad 60'. Dadurch bilden die Pumpenräder 59' und 60' ein Untersetzungsgetriebe für die Kühlmittelpumpe 22'. Das treibende Pumpenrad 59' ist auf einer im Pumpengehäuse 72 gelagerten Welle 76 drehfest befestigt. Die Welle 76 ist koaxial zu einer Nebenantriebswelle 51' der nicht weiter dargestellten Brennkraftmaschine angeordnet und mit der Nebenantriebswelle 51' über eine Steckkupplung 77 antriebsverbunden.A pump housing 72 with its mounting surface 73 is fastened to a connection surface 71 of a housing part 6 'of an internal combustion engine (not shown further). The pump housing 72 contains pump wheels 59 'and 60' of a lubricating oil gear pump in a section 74 facing the housing part 6 'and a coolant pump 22' with a pump impeller 58 'in the opposite section. A housing cover 75 forms the end. The driving pump wheel 59 'of the lubricating oil gear pump has a smaller number of teeth than the driven pump wheel 60'. As a result, the pump wheels 59 'and 60' form a reduction gear for the coolant pump 22 '. The driving pump wheel 59 ′ is fastened in a rotationally fixed manner on a shaft 76 mounted in the pump housing 72. The shaft 76 is arranged coaxially to a power take-off shaft 51 'of the internal combustion engine (not shown further) and drive-connected to the power take-off shaft 51' via a plug-in coupling 77.
