Die Erfindung betrifft eine Brennkraftmaschine mit einem Kurbelgehäuse, in dem eine Kurbelwelle drehbar gelagert ist, an der zumindest ein einen Kolben tragendes Pleuel angelenkt ist, wobei der Kolben in einem von einem Zylinderkopf unter Bildung eines Arbeitsraumes abgedeckten Zylinder bewegbar ist und wobei in das Kurbelgehäuse zumindest eine Ausnehmung eingelassen ist, in die eine Ölpumpe und eine Kühlflüssigkeitspumpe einsetzbar ist, die hintereinanderliegend angeordnet von einem gemeinsamen Antriebsrad angetrieben in eine gemeinsame Ausnehmung eingesetzt sind, wobei die Ausnehmung in eine Schürze des Kurbelgehäuses als durchgehende Öffnung eingelassen und einseitig zu einer Stirnseite des Kurbelgehäuses ausgerichtet ist.The invention relates to an internal combustion engine with a crankcase, in which a crankshaft is rotatably mounted, at least a connecting rod carrying a piston is articulated, the Piston in one of a cylinder head to form a work space covered cylinder is movable and being in the crankcase at least one recess is let into the one Oil pump and a coolant pump can be used, the one behind the other arranged by a common drive wheel are driven into a common recess, wherein the recess in an apron of the crankcase as a continuous Inlet opening and one side to a front of the Crankcase is aligned.
Eine derartige Brennkraftmaschine ist aus der EP 05 05 346 A1 bekannt. Das in diesem Dokument beschriebene Kurbelgehäuse weist insbesondere in das Kurbelgehäuse integrierte Kanäle zur Führung von Schmieröl und Kühlwasser einschließlich der entsprechenden Ölpumpe und Kühlflüssigkeitspumpe auf. Wie beispielsweise die notwendigen Wärmetauscher an den Ölkreislauf und den Kühlflüssigkeitskreislauf angeschlossen werden ist nicht Gegenstand dieser Patentanmeldung.Such an internal combustion engine is known from EP 05 05 346 A1. The crankcase described in this document has in particular, channels integrated into the crankcase for guidance of lubricating oil and cooling water including the corresponding oil pump and coolant pump. Such as the necessary ones Heat exchanger on the oil circuit and the coolant circuit is not the subject of this Patent application.
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine bereit zu stellen, bei der die Anordnung und Montage von Anbauteilen verbessert ist. The invention has for its object an internal combustion engine to provide, in the arrangement and assembly of attachments is improved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Kühlflüssigkeitsthermostatgehäuse an das Kurbelgehäuse montiert ist, wobei das Kühlflüssigkeitsthermostatgehäuse einen Wärmetauscherzuflussanschluss und einen Wärmetauscherrückflussanschluss mit integriertem Thermostatventil sowie einen Heizungsvorlaufanschluss und einen Heizungsrücklaufanschluss aufweist. Damit sind an einem einzigen Bauteil sämtliche nötigen externen Anschlussmöglichkeiten für den Kühlflüssigkeitskreislauf integriert, so dass hier eine übersichtliche Montagemöglichkeit geschaffen ist.This object is achieved in that a coolant thermostat housing is mounted on the crankcase, wherein the coolant thermostat housing a heat exchanger inlet connection and a heat exchanger return connection with integrated thermostatic valve and a heating flow connection and has a heating return connection. So that is at one single component all the necessary external connection options integrated for the coolant circuit, so that here a clear Installation possibility is created.
In weiterer Ausgestaltung der Erfindung ist das Kühlflüssigkeitsthermostatgehäuse quer zu der Öffnung an das Kurbelgehäuse montiert. Dadurch sind die entsprechenden Anschlüsse an der Längsseite der Brennkraftmaschine zugänglich und aus dem Bereich des Rädertrieb herausgezogen.In a further embodiment of the invention, the coolant thermostat housing mounted across the opening on the crankcase. As a result, the corresponding connections are on the long side of the Internal combustion engine accessible and from the area of the wheel drive pulled out.
Durch die hintereinanderliegende Anordnung der beiden Pumpen in einer durchgehenden Öffnung in einer Schürze des Kurbelgehäuses ist im Übrigen der Herstellungsaufwand des Kurbelgehäuses gegenüber bekannten Lösungen dadurch reduziert, dass beispielsweise beim Gießen des Kurbelgehäuses nur noch ein entsprechend geformter durchgehender Gießkern benötigt wird. Auch die nachfolgende mechanische Bearbeitung ist dadurch, dass beispielsweise nur eine durchgehende Öffnung vorhanden ist, vereinfacht. Dadurch, dass die Öffnung durchgehend ist, ist darüber hinaus der Gießkern auf beiden Seiten optimal fixierbar und ebenfalls die anschließende Entfernung des Gießkerns leichter durchführbar, wie auch die Reinigung. Durch den gemeinsamen Antrieb von einem gemeinsamen Antriebsrad von einer Stirnseite des Kurbelgehäuses aus ist der Rädertrieb gegenüber konventionellen Lösungen mit nebeneinanderliegenden Pumpen und mindestens ein Antriebsrad verringert. Due to the consecutive arrangement of the two pumps in a through opening in an apron of the crankcase is compared to the manufacturing cost of the crankcase known solutions reduced, for example, that when casting the crankcase only a correspondingly shaped one continuous casting core is required. The following too mechanical processing is characterized in that, for example only one through opening is available, simplified. Thereby, the pouring core is also that the opening is continuous optimally fixable on both sides and also the subsequent one Removal of the casting core is easier to carry out, as is cleaning. By the common drive from a common The drive wheel from one end of the crankcase is the wheel drive compared to conventional solutions with side by side Pumps and at least one drive wheel reduced.
In Weiterbildung der Erfindung ist das Antriebsrad auf der Stirnseite außerhalb der Öffnung angeordnet und die Ölpumpe und die Kühlflüssigkeitspumpe sind in dieser Reihenfolge an das Antriebsrad anschließend in der Öffnung angeordnet. Dadurch ist es möglich, die notwendigen Mediumsführungen zu bzw. von den Pumpen in dem Kurbelgehäuse anzuordnen, während der Antrieb zugänglich außerhalb der Öffnung angeordnet ist.In a further development of the invention, the drive wheel is on the end face arranged outside the opening and the oil pump and the coolant pump are connected to the drive wheel in this order arranged in the opening. This makes it possible to necessary media guides to or from the pumps in the Arrange crankcase while the drive is accessible outside the opening is arranged.
Weiterhin sind die Ölpumpe und die Kühlflüssigkeitspumpe einschließlich dem Antriebsrad vormontiert und als Baueinheit an die Brennkraftmaschine angebaut. Somit kann die Baueinheit ggf. als Zulieferteil hergestellt werden und bei der Fließbandmontage komplett angebaut werden. Dadurch, dass für beide Pumpen nur eine einzige Baueinheit zur Anwendung kommt, ist die Montagezeit insgesamt verkürzbar.The oil pump and coolant pump are also included the drive wheel pre-assembled and as a unit to the Internal combustion engine attached. Thus, the unit can possibly be as Supplier part to be manufactured and complete during assembly line assembly be grown. Because only one for both pumps the only component used is the total assembly time shortened.
In weiterer Ausgestaltung der Erfindung sind die Gehäuseteile von Ölpumpe und Kühlflüssigkeitspumpe aus Aluminium, vorzugsweise im Druckgießverfahren hergestellt. Dies stellt eine herstellungsmäßig günstige Ausbildungsform dar. Selbstverständlich ist es aber im Rahmen der Erfindung auch möglich, hier andere Materialien und Gießverfahren anzuwenden.In a further embodiment of the invention, the housing parts of Oil pump and coolant pump made of aluminum, preferably manufactured in the die casting process. This represents a manufacturing inexpensive form of training. Of course it is within the framework the invention also possible, here other materials and casting processes apply.
In Weiterbildung der Erfindung ist in die Öffnung ein Absatz eingelassen, der eine Anlagefläche für die Baueinheit bildet. Dies bildet eine besonders vorteilhafte Ausgestaltung, da somit bei der Montage die Baueinheit bis zum Anschlag in die Öffnung eingeschoben wird und mit Befestigungen am Kurbelgehäuse verspannt wird. Die Befestigungen sind ungleichmäßig verteilt, so dass auch in Urrifangsrichtung eine exakte Positionierung gewährleistet ist. Eine Falschmontage ist damit ausgeschlossen. In a development of the invention, a paragraph is let into the opening, which forms a contact surface for the structural unit. This forms one Particularly advantageous embodiment, since the Assembly is pushed into the opening as far as it will go and is clamped with fastenings on the crankcase. The fortifications are distributed unevenly, so that it is also in the original direction exact positioning is guaranteed. A wrong assembly is excluded.
Weiterhin sind ein Ölsaugraum und ein Öldruckraum in das Kurbelgehäuse eingelassen, ebenso wie ein Kühlflüssigkeitsdruckraum in das Kurbelgehäuse direkt eingelassen ist. Damit sind bis auf die Kühlflüssigkeitszufuhr sämtliche Mediumsführungen direkt in das Kurbelgehäuse integriert, so dass hier keine zusätzlichen externen Leitungen oder Anschlüsse nötig sind.There is also an oil suction chamber and an oil pressure chamber in the crankcase recessed, as well as a coolant pressure chamber in the Crankcase is directly embedded. This is except for the coolant supply all media guides directly into the crankcase integrated, so there are no additional external cables or connections are necessary.
In Weiterbildung der Erfindung ist das Kühlflüssigkeitspumpenrad von einem Deckel abgedeckt, der die Öffnung auf der dem Antriebsrad gegenüberliegenden Seite verschließt. Dadurch ist im Wartungsoder Reparaturfall das Kühlflüssigkeitspumpenrad und eine danebenliegende Ringdichtung ohne aufwendige Demontage der kompletten Kühlflüssigkeitspumpe und der Ölpumpe leicht zugänglich und kann ggf. gewechselt werden.In a further development of the invention, the coolant pump wheel covered by a lid covering the opening on the drive wheel closes opposite side.
