Aus der von der Anmelderin stammenden DE 198 55 562 C1 ist ein Kurbelgehäuse bekannt. Dieses weist neben dem Kurbelwellenraum weitere Kammern auf, welche sich von der Längsseite des Kurbelgehäuses in das Innere erstrecken. Diese Kammern werden aus den beiden Stirnwänden, einem Teil der Grundfläche und einer den Kurbelwellenraum begrenzenden Wand gebildet. In den Kammern sind die Hilfsaggregate, insbesondere Pumpen und Wärmetauscher, Filtern- und Ölvorratsräume, angeordnet. Bei der Komplettierung werden die Hilfsaggregate von der Längsseite her montiert. Danach werden die Kammern mittels eines seitlichen Deckels abgedichtet. Im Bereich des Kurbelwellenraumes ist die Grundfläche des Kurbelgehäuses durch eine Abdeckplatte verschlossen.A crankcase is known from the applicant's DE 198 55 562 C1. In addition to the crankshaft chamber, this has further chambers which extend from the long side of the crankcase into the interior. These chambers are formed from the two end walls, part of the base area and a wall delimiting the crankshaft space. The auxiliary units, in particular pumps and heat exchangers, filter and oil storage rooms, are arranged in the chambers. When completed, the auxiliary units are assembled from the long side. The chambers are then sealed using a side cover. In the area of the crankshaft space, the base area of the crankcase is closed by a cover plate.
Ausgehend vom zuvor beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, diesen im Hinblick auf eine montagefreundlichere Lösung weiterzuentwickeln.Starting from the prior art described above, the object of the invention is to develop it further with a view to a more assembly-friendly solution.
Die Aufgabe wird erfindungsgemäß durch eine Abdeckplatte für ein Kurbelgehäuse gelöst, welche sich über die gesamte Grundfläche des Kurbelgehäuses erstreckt. Gemäß Anspruch 2 sind auf dieser Abdeckplatte die Hilfsaggregate montiert, so dass diese eine bauliche Einheit bilden. Und in Ausgestaltung hierzu wird vorgeschlagen, dass die Abdeckplatte Kanäle zur Medien-Führung sowie Ausnehmungen aufweist.The object is achieved according to the invention by a cover plate for a crankcase, which extends over the entire base area of the crankcase. According to claim 2, the auxiliary units are mounted on this cover plate, so that they form a structural unit.

Die erfindungsgemäße Lösung und deren Ausgestaltungen bietet den Vorteil, dass die Abdeckplatte mit den Hilfsaggregaten in einem Arbeitsgang von der Unterseite des Kurbelgehäuses her eingesetzt werden kann. Gegenüber dem Stand der Technik ergibt sich somit ein geringerer Montageaufwand bzw. eine verbesserte Servicefreundlichkeit. Über die Integration der Kanäle zur Medien-Führung in der Abdeckplatte wird die Anzahl der Dichtstellen des Kurbelgehäuses verringert. Beim Kurbelgehäuse gemäß dem Stand der Technik wird beispielsweise die Verbindungsleitung zwischen einer Pumpe und einem Wärmetauscher durch den Kurbelwellenraum hindurchgeführt. Demgegenüber können jetzt bei der Herstellung des Kurbelgehäuses die entsprechenden Durchführungen für die Leitungen entfallen. Hieraus resultiert eine Kosten-Reduktion bei der Herstellung des Kurbelgehäuses.The solution according to the invention and its embodiments offer the advantage that the cover plate with the auxiliary units can be used in one operation from the underside of the crankcase. Compared to the prior art, this results in less installation effort or improved serviceability. The number of sealing points on the crankcase is reduced by integrating the channels for media guidance in the cover plate. For the crankcase according to the status In technology, for example, the connecting line between a pump and a heat exchanger is passed through the crankshaft chamber. In contrast, the corresponding bushings for the lines can now be omitted in the manufacture of the crankcase. This results in a cost reduction in the manufacture of the crankcase.

The two suction pumps convey the lubricant located in the two suction points 10 and 11 into the channel 13 via channels 18 and 19. The degassed and calmed lubricant is then sucked in by the pressure pump DP via the suction channel 15. The pressure pump DP conveys the lubricant via channel 17, volume V2, to the heat exchangers 6. As shown in FIG. 4, the fluid guide device 12 is embodied in one piece with the cover plate 2. The lubricant dripping from the crankshaft chamber 9 is fed to the two suction points 10 and 11 by means of the fluid guide device 12. In this sectional view, the channel 18, that is the connection from the first suction point 10 to the suction pump SP1, is located within the fluid guide device 12. Figure 5 shows a second sectional view through the left side of the crankcase 1 with cover plate 2 along the line V. In this section, recesses 20 can be seen. These are located around the channels for media guidance. Exceptions to this are the areas for sealing, for example cover plate 2 for crankcase 1 with respect to the environment, area C, and areas for screwing. The degassed and calmed lubricant of the chambers 5 can reach the suction channel 15 via these recesses 20. Via the suction channel 15, the lubricant is conveyed from the pressure pump DP via channel 17 to the heat exchangers 6. The statements made under FIG. 4 apply to the function of the fluid guide device 12.
Figur 6 zeigt ein drittes Schnittbild durch die rechte Hälfte des Kurbelgehäuses 1 mit der Abdeckplatte 2. Bei diesem Schnitt sind die Anschlüsse eines Wärmetauschers 6 ersichtlich. Über den Kanal 17 wird das von der Druckpumpe DP geförderte Schmiermittel zugeführt. Über den Kanal 16 wird das Schmiermittel nach dem Wärmetauscher 6 einem Olfilter zugeführt. Die beiden Kanäle 14 dienen zu Zu- und Abfuhr des Kühlerwassers. Wie aus dem zuvor beschriebenen ersichtlich, erstreckt sich die Abdeckplatte 2 über die gesamte Grundfläche des Kurbelgehäuses 1. Auf dieser Abdeckplatte 2 sind die Hilfsaggregate, insbesondere Wärmetauscher und Pumpen sowie Olfilter, montiert. Diese bilden zusammen mit der Abdeckplatte 2 eine bauliche Einheit. Hierdurch können die Abdeckplatte 2 mit den darauf montierten Hilfsaggregaten in einem Arbeitsgang in das Kurbelgehäuse, von der Unterseite her, montiert werden.FIG. 6 shows a third sectional view through the right half of the crankcase 1 with the cover plate 2. The connections of a heat exchanger 6 can be seen in this section. The lubricant delivered by the pressure pump DP is supplied via the channel 17. Via the channel 16, the lubricant is fed to an oil filter after the heat exchanger 6. The two channels 14 serve to supply and discharge the cooler water. As can be seen from what has been described above, the cover plate 2 extends over the entire base area of the crankcase 1. The auxiliary units, in particular heat exchangers and pumps and oil filters, are mounted on this cover plate 2. Together with the cover plate 2, these form a structural unit. As a result, the cover plate 2 with the auxiliary units mounted thereon can be installed in the crankcase from the bottom in one operation.
Die erfindungsgemäße Lösung bietet gegenüber dem Stand der Technik folgende Vorteile:The solution according to the invention offers the following advantages over the prior art:
1. eine einfachere Kanalführung für die Medien. Hieraus ergeben sich weniger Schnittstellen und eine Verringerung der Strömungsverluste.1. an easier channel guide for the media. This results in fewer interfaces and a reduction in flow losses.
2. weniger Durchführungsöffnungen für die Medienkanäle im Kurbelgehäuse. Hierdurch lässt sich das Kurbelgehäuse mit weniger Aufwand, also kostengünstiger, herstellen. Ein weiterer Vorteil besteht darin, dass die Funktionseinheit2. fewer through openings for the media channels in the crankcase. As a result, the crankcase can be produced with less effort, that is to say more cost-effectively. Another advantage is that the functional unit
Kurbelgehäuse/Abdeckplatte besser an Kundenwünsche adaptiert werden kann. Daneben wird die Ausfallwahrscheinlichkeit, z. B. auf Grund von Porositäten, verringert. 3. erhöhte Servicefreundlichkeit.Crankcase / cover plate can be better adapted to customer requirements. In addition, the probability of failure, e.g. B. due to porosities. 3. Increased ease of service.
4. die seitlichen Deckel zum Verschließen der Kammern 5 entfallen. Hieraus resultiert eine Steigerung der Steifigkeit des Kurbelgehäuses insgesamt.4. the side covers for closing the chambers 5 are omitted. This results in an increase in the overall rigidity of the crankcase.
5. Die Motorlagerung kann an der Abdeckplatte 2 angreifen bzw. der Motor kann darauf abgestellt werden. 5. The engine mounting can engage on the cover plate 2 or the engine can be parked on it.
