Diese Brennkraftmaschine weist ein Kühlwasserpumpenmodul auf, das als eigenständiges Gussgehäuse ausgebildet ist und an der Frontseite der Brennkraftmaschine befestigt ist. Dieses Gussgehäuse dient gleichzeitig als Befestigung aller übrigen Hilfsgeräte der Brennkraftmaschine, wobei ein kompliziertes System von Stützen vorhanden ist, das Hilfsgeräte aufnimmt. Insgesamt handelt es sich dabei um ein kompliziertes Gebilde, wobei die einzelnen Hilfsgeräte über mehrere Riemen in verschiedenen Ebenen angetrieben werden.Such an internal combustion engine is known from DE-A 22 46 455. This internal combustion engine has a cooling water pump module on, which is designed as an independent cast housing and on the Front of the engine is attached. This cast housing serves at the same time as attachment of all other auxiliary devices of the internal combustion engine being a complicated system of supports is that accepts auxiliary devices.

Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine mit einem Kühlwasserpumpenmodul anzugeben, dass durch Anordnung und Ausbildung eine bauliche Vereinfachung der Brennkraftmaschine bewirkt. The invention has for its object an internal combustion engine with a cooling water pump module to indicate that by arrangement and training a structural simplification of the internal combustion engine causes.

Diese Aufgabe wird dadurch gelöst, dass das Kühlwasserpumpenmodul im Bereich des Übergangs von der Frontseite zu einer Seitenwand der Brennkraftmaschine angeordnet ist und dass der Kanal in Form eines Übergangskanals in Strömungsverbindung mit einem Ölkühlermodul steht. Dadurch, dass das Kühlwasserpumpenmodul im Bereich des Übergangs von der Frontseite zu einer Seitenwand der Brennkraftmaschine angeordnet ist, verbleibt an der restlichen Frontseite noch Platz für weitere Einrichtungen, die direkt an das Kurbelgehäuse oder einem Räder- bzw. Kettenkasten angeordnet und befestigt sind. Weiterhin steht der in das Kühlwasserpumpenmodul integrierte Kühlwasserkanal in Verbindung mit einem Ölkühlermodul. Dies erfolgt ohne weitere Leitung durch direktes Aneinanderstoßen der beiden Module. Dabei kann das Ölkühlermodul auf der Frontseite neben dem Kühlwassermodul angeordnet und gegebenenfalls einstückig mit dem Kühlwassermodul ausgebildet sein, oder aber in bevorzugter Weiterbildung ist das Ölkühlermodul an der Seitenwand der Brennkraftmaschine angeordnet, die an das Kühlwasserpumpenmodul angrenzt. Dabei ist dann entweder das Kühlwasserpumpenmodul oder das Ölkühlermodul über die Seitenwand bzw. die Frontseite hinausgezogen, so dass auch bei dieser Anordnung eine direkte leitungslose Verbindung des Übergangskanals mit dem Ölkühlermodul besteht. Auch bei dieser Anordnung können die beiden Module eigenständig oder einstückig ausgebildet sein.This task is solved in that the cooling water pump module in the area of the transition from the front to a side wall the internal combustion engine is arranged and that the channel in Form of a transition channel in flow connection with an oil cooler module stands.

It is also in the cooling water pump module Integrated cooling water channel in connection with an oil cooler module. This is done by direct collision without any further cables of the two modules. The oil cooler module can be on the front arranged next to the cooling water module and optionally in one piece be formed with the cooling water module, or in A preferred further development is the oil cooler module on the side wall the internal combustion engine arranged to the cooling water pump module borders. Then either the cooling water pump module or the oil cooler module via the side wall or the front pulled out, so that even with this arrangement a direct wireless connection of the transition duct to the oil cooler module consists. With this arrangement, the two modules be formed independently or in one piece.

In weiterer Ausgestaltung der Erfindung sind an dem Kühlwasserpumpenmodul Anschlüsse zur Verbindung mit einem Kühlwasserwärmetauscher und einem Ausgleichsbehälter angebracht. Diese beiden Anschlüsse sind so angeordnet, dass sie einerseits außerhalb des Laufbereiches des Riemens liegen und andererseits über einen kurzen Schlauch sowohl der Kühlwasserwärmetauscher als auch der Ausgleichsbehälter angeschlossen werden können. Dabei ist der Anschluss zur Verbindung mit dem Ausgleichsbehälter bevorzugt im Anbindungsbereich des Anschlusses für den Schlauch zu dem Kühlwasserwärmetauscher angeordnet.In a further embodiment of the invention are on the cooling water pump module Connections for connection to a cooling water heat exchanger and an expansion tank attached. This Both connections are arranged so that they are outside on the one hand the running range of the belt and on the other hand over a short hose of both the cooling water heat exchanger and the Expansion tank can be connected. Here is the connection for connection to the expansion tank preferably in Connection area of the connection for the hose to the cooling water heat exchanger arranged.

In Weiterbildung der Erfindung ist ein von einem Thermostatventilmodul abzweigender Kühlwasserkurzschluss leitungslos mit dem Kühlwasserpumpenmodul verbunden. Leitungslos heißt, dass keine externe Leitung, beispielsweise in Form eines Schlauchs, vorhanden ist. Dabei kann im Rahmen der Erfindung das Thermostatventilmodul auch einstückig mit dem Kühlwasserpumpenmodul ausgebildet sein. Somit kann das Kühlwasserpumpenmodul komplett mit allen erforderlichen Bauteilen vorgefertigt werden und als komplette Einheit an die Brennkraftmaschine angebaut werden. Dabei ist das Kühlwasserpumpenmodul auch für Brennkraftmaschinen einer Baureihe mit unterschiedlichen Zylinderzahlen geeignet, wobei gegebenenfalls beispielsweise unterschiedliche leistungsfähige Wasserpumpen verbaut werden.In a further development of the invention is a thermostatic valve module branching cooling water short circuit with the Cooling water pump module connected. Wireless means that none external line, for example in the form of a hose, is available is. The thermostatic valve module can be used within the scope of the invention also be integrally formed with the cooling water pump module. This means that the cooling water pump module can be completely equipped with all the necessary Components are prefabricated and as a complete unit to the Internal combustion engine to be grown. Here is the cooling water pump module also for internal combustion engines of a series different numbers of cylinders, where appropriate, for example different powerful water pumps installed become.

In Weiterbildung der Erfindung ist an dem Kühlwasserpumpenmodul ein Befestigungssattel für einen Generator angeordnet. Dabei ist der Befestigungssattel so angeordnet, dass der Generator oberhalb des Ölkühlermoduls angeordnet ist und von dem gleichen Riemen angetrieben wird, der auch die Kühlwasserpumpe antreibt.A further development of the invention is on the cooling water pump module a mounting saddle arranged for a generator. Here is the Mounting saddle arranged so that the generator above the Oil cooler module is arranged and driven by the same belt that also drives the cooling water pump.

In Weiterbildung der Erfindung ist der Riemen über eine Umlenkrolle und einen Riemenspanner geführt. Dabei sind die Umlenkrolle und der Riemenspanner so angeordnet, dass ausreichende Umschlingungswinkel an den einzelnen Antriebsrollen vorhanden sind, wobei in weiterer Ausgestaltung die Umlenkrolle den Antrieb für eine in das Kühlwasserpumpenmodul integrierte Kraftstoffförderpumpe darstellt.In a development of the invention, the belt is over a deflection roller and a belt tensioner. Here are the pulley and the belt tensioner is arranged so that sufficient wrap angle are present on the individual drive rollers, whereby In a further embodiment, the deflection roller is the drive for one in the Cooling water pump module integrated fuel pump.

In Weiterbildung der Erfindung ist an dem Ölkühlermodul ein Ölfilter angeordnet. Dadurch werden keine zusätzlichen Leitungen zu einem an einer anderen Stelle der Brennkraftmaschine angeordneten Ölfilter benötigt.In a further development of the invention, an oil filter is on the oil cooler module arranged. This means that no additional lines become one oil filter arranged at another location of the internal combustion engine needed.

In Weiterbildung der Erfindung sind in das Ölkühlermodul alle erforderlichen Ventile und Sensoren für den Ölkreislauf integriert. Damit ergibt sich auch bei dem Ölkühlermodul die Möglichkeit, dieses weitgehend vorzumontieren und als Einheit an die Brennkraftmaschine anzubauen.In a further development of the invention, all necessary are in the oil cooler module Valves and sensors for the oil circuit integrated. In order to the oil cooler module also offers the possibility of doing this largely pre-assembled and as a unit to the internal combustion engine grow.

In weiterer Ausgestaltung der Erfindung sind das Ölkühlermodul und/oder das Kühlwasserpumpenmodul die Anschraubbasis für ein Brennkraftmaschinensteuergerät. Dies hat den Vorteil, dass für das Brennkraftmaschinensteuergerät ein günstiger Anbauplatz zur Verfügung steht, da die erforderlichen Leitungsanschlüsse zu den Sensoren, Ventilen und sonstigen Bauteilen in bzw. an der Brennkraftmaschine über kurze Leitungen herstellbar sind.In a further embodiment of the invention, the oil cooler module and / or the cooling water pump module the screw-on base for one Engine control unit.

In weiterer Ausgestaltung ist ein ebenfalls frontseitig angeordnetes Schmierölpumpengehäuse mit dem Kühlwasserpumpenmodul einteilig ausgebildet und das Ölkühlermodul ist von hinten dagegen geschraubt. Die Dichtfläche des Schmierölpumpengehäuses und des Ölkühlermoduls liegt auf einer Ebene und bildet so die Anflanschfläche für das Ölkühlermodul außerhalb der Dichtfläche zu dem Kurbelgehäuse. In einer weiteren Zusammenfassung kann ein Komplettmodul das Thermostatventilmodul, das Kühlwasserpumpenmodul, das Schmierölpumpengehäuse und einen Träger für ein Lüfterrad umfassen. Dieses Komplettmodul kann mit Ölpumpe, Kühlwasserpumpe, Wellendichtring für die Kurbelwelle und dem Thermostatventil vorkomplettiert an das Montageband angeliefert werden. Die stirnseitige Anflanschung des Kühlwasserpumpenmoduls an das Ölkühlermodul reduziert Umlenkungen des Kühlwasserstroms und verringert damit den kühlmittelseitigen Strömungswiderstand. In a further embodiment, one is also arranged on the front Lubricating oil pump housing with the cooling water pump module, one-piece trained and the oil cooler module is against it from behind screwed. The sealing surface of the lubricating oil pump housing and the Oil cooler module lies on one level and thus forms the flange surface for the oil cooler module outside the sealing surface to the crankcase. In a further summary, a complete module the thermostatic valve module, the cooling water pump module, the Lubricating oil pump housing and a support for a fan wheel include. This complete module can be equipped with an oil pump, cooling water pump, Shaft sealing ring for the crankshaft and the thermostatic valve pre-assembled be delivered to the assembly line. The front Flange the cooling water pump module to the oil cooler module reduces deflections of the cooling water flow and thus reduces the flow resistance on the coolant side.
