Abstract
Description
Die Erfindung betrifft ein Kurbelgehäuse für eine flüssigkeitsgekühlte Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a crankcase for a liquid-cooled internal combustion engine with the Features of the preamble of claim 1.
Sie
geht von der deutschen Offenlegungsschrift
Nachteilig an dieser Ausgestaltung ist der tief in Richtung Steg eingezogene Zwickelbereich, in dem sich die Kühlmittelströmung aufgrund der Umlenkung nur sehr schlecht ausbildet, weshalb die Kühlung des Steges nicht besonders effizient ist.adversely in this embodiment, the retracted deep in the direction of the web Gusset area in which the coolant flow due to the deflection only very bad forms, which is why the cooling the bridge is not very efficient.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, den Stegbereich für eine gattungsgemäße Brennkraftmaschine besser zu kühlen.task the present invention is to show a measure the bridge area for a generic To cool the internal combustion engine better.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the feature in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung können in der Nähe des thermisch hoch belasteten Steges höhere Strömungsgeschwindigkeiten erreicht werden, so dass gegenüber einem tiefeingezogenen Kühlmittelkanal in Richtung Steg eine bessere Kühlwirkung erreicht wird. Weiter tritt kein großer Steifigkeitsverlust im Stegbereich auf. Da große Querschnittssprünge im Kühlmittelkanal vermieden werden und die Strömung sehr gezielt im thermisch hoch belasteten Bereich geführt wird, kann die Förderleistung der Kühlmittelpumpe und damit die Verluste niedrig gehalten werden. Dazu trägt auch die Tatsache bei, dass der Kühlmittelkanal wenige Umlenkungen und Querschnittssprünge aufweist. In Summe ergibt sich eine steifere Kurbelgehäusestruktur, die die gleiche Lebensdauer bzw. eine höhere Belastbarkeit des Kurbelgehäuses aufweist. Somit ist eine Leistungssteigerung bzw. eine Zünddrucksteigerung für die Brennkraftmaschine möglich, bei gleichzeitig niedrigeren Bauteiltemperaturen und einer reduzierten Kühlmittelpumpenleistung.By the embodiment of the invention can higher near the thermally highly loaded bridge Flow rates are achieved so that opposite a deep drawn coolant channel towards the bridge a better cooling effect is achieved. Next, no occurs high loss of stiffness in the web area. Because big Cross-section jumps avoided in the coolant channel be and the flow very targeted in the thermally highly loaded Area is guided, the delivery rate the coolant pump and thus kept the losses low become. This is also helped by the fact that the coolant channel has few deflections and cross-sectional jumps. In Sum results in a stiffer crankcase structure, the same life or a higher load capacity having the crankcase. Thus, an increase in performance or an ignition pressure increase for the internal combustion engine possible, at the same time lower component temperatures and a reduced coolant pump capacity.
Die Unteransprüche beschreiben Weiterbildungen der erfindungsgemäßen Ausgestaltung des Kurbelgehäuses.The Subclaims describe developments of the invention Embodiment of the crankcase.
Im Folgenden ist die Erfindung anhand von vier besonders bevorzugten Ausführungsbeispielen in neun Figuren näher erläutert.in the The invention is based on four particularly preferred Embodiments explained in more detail in nine figures.
