Schallemissionen auch Ölwannen,
die sich durch eine geringe Schallabstrahlung auszeichnen. Um die
von Ölwannen ausgehende
Schallabstrahlung zu verringern, ist es bekannt, Ölwannen
aus schwingungsdämpfenden Verbundmaterial
herzustellen. Aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine akustisch wirksame Ölwanne mit verminderter Schallabstrahlung zu schaffen, die ein relativ geringes Gewicht aufweist und wirtschaftlich herstellbar ist.The present invention lies based on the task of an acoustically effective oil pan with reduced sound radiation to create that is relatively light weight and economical can be produced.
Diese Aufgabe wird bei einer Ölwanne der eingangs genannten Art durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Die erfindungsgemäße Ölwanne ist im wesentlichen dadurch gekennzeichnet, dass die Wandung des wannenförmigen Körpers teilweise durch ein mehrlagiges Teil ersetzt ist, das mindestens eine Lage aus einem Metall und mindestens eine aus Kunststoff oder einem viskoelastischen Material gebildete Lage aufweist, wobei das mehrlagige Teil an seinem Rand mit dem Kunststoff der Ölwannenwandung umspritzt ist.This task is the beginning of an oil pan mentioned type by the specified in the characterizing part of claim 1 Features solved. The oil pan according to the invention is essentially characterized in that the wall of the trough-shaped body partially is replaced by a multi-layer part that has at least one layer made of a metal and at least one made of plastic or a viscoelastic Material formed layer, the multilayer part on its Edge with the plastic of the oil pan wall is encapsulated.
Die erfindungsgemäße Ölwanne zeichnet sich durch ein relativ geringes Gewicht und eine erheblich verringerte Schallabstrahlung aus. Auch lässt sie sich relativ kostengünstig herstellen.The oil pan according to the invention is characterized by a relatively low weight and significantly reduced sound radiation out. She also leaves themselves relatively inexpensively produce.
Die Erfindung basiert auf der Erkenntnis, dass bei einer herkömmlichen Ölwanne vom Wannenboden in der Regel die stärkste Schallabstrahlung ausgeht. Bei der erfindungsgemäßen Ölwanne ist daher das mehrlagige schalldämpfende Teil bevorzugt im Wannenboden angeordnet. Es kann insbesondere als einfaches zweidimensionales Stanzteil hergestellt und in eine Spritzgießform derart eingelegt und über geeignete Absperrkanten gehalten werden, dass es randseitig mit dem Kunststoff der Ölwannenwandung umspritzt wird. Bei der Verwendung von ebenen, d.h. zweidimensionalen Stanzteilen ergeben sich niedrige Werkzeugkosten und eine einfache Handhabung, so dass sich die erfindungsgemäße Ölwanne entsprechend kostengünstig herstellen lässt.The invention is based on the knowledge that with a conventional oil pan from The bottom of the tub is usually the strongest Emits sound. In the oil pan according to the invention, therefore, is the multi-layer sound deadening Part preferably arranged in the tub floor. It can in particular as simple two-dimensional stamped part and manufactured in an injection mold inserted and over suitable barrier edges are held so that it is on the edge the plastic of the oil pan wall is encapsulated. When using flat, i.e. two-dimensional Stamped parts result in low tooling costs and a simple one Handling, so that the oil pan according to the invention can be produced accordingly inexpensively.
In vorteilhafter Weise kann das mehrlagige, akustisch wirksame Teil aber auch als Formteil ausgebildet sein. Hierdurch lässt sich die Festigkeit der erfindungsgemäßen Ölwanne erhöhen. Das mehrlagige, akustisch wirksame Teil kann dabei insbesondere den Wannenboden der Ölwanne bilden. In diesem Fall ist das Formteil schalenförmig ausgebildet und weist vorzugsweise einen abgewinkelten oder gewellten, umlaufenden Rand auf. Ein derart geformter Rand ermöglicht eine besonders robuste Anbindung des mehrlagigen schalenförmigen Formteils an der im Kunststoff-Spritzgießverfahren hergestellten Ölwannenwandung. Insbesondere ist eine abgewinkelte Gestaltung des Randes des mehrlagigen schalenförmigen Formteils für den Spritzgießprozess vorteilhaft, da das Formteil dann als Einleger im Spritzgießwerkzeug direkt an die Kunststoffseitenwände formschlüssig angespritzt werden kann. Auf diese Weise kann der zur Herstellung der Ölwannenwandung in das Spritzgußwerkzeug eingespritzte Kunststoff gegenüber der übrigen freiliegenden Oberfläche des Formteils abgesperrt werden. Insbesondere gestaltet sich dann die Ausführung der Absperrkanten im Spritzgießwerkzeug relativ einfach.Advantageously, the multilayer, acoustically effective part but also be formed as a molded part. hereby let yourself increase the strength of the oil pan according to the invention. The multilayer, acoustically effective part can in particular the Pan bottom of the oil pan form. In this case, the molded part is bowl-shaped and has preferably an angled or corrugated peripheral edge on. Such a shaped edge enables a particularly robust Connection of the multilayer shell-shaped molded part to the in Plastic injection molding manufactured oil pan wall. In particular, an angled design of the edge of the multilayer cupped Molding for the injection molding process advantageous because the molded part then as an insert in the injection mold molded directly onto the plastic side walls can be. In this way it can be used to manufacture the oil pan wall into the injection mold injected plastic opposite the rest exposed surface of the Shut off part. In particular, the execution the barrier edges in the injection mold pretty easy.
Eine weitere bevorzugte Ausgestaltung der erfindungsgemäßen Ölwanne besteht darin, dass das mehrlagige Teil eine oder mehrere Bohrungen oder Ausnehmungen aufweist, an der/denen eine oder mehrere in die Ölwanne hineinragende Rippen formschlüssig angebracht sind. Die jeweiligen Rippen werden in einem Arbeitsschritt mit der Ölwanne im selben Spritzgießwerkzeug ausgeformt. Der Formschluß zwischen den Rippen und dem mehrlagigen Teil wird über Löcher in dem mehrlagigen Teil realisiert. Die Rippen haben die Funktion von Ölschwallrippen, die eine Vergleichmäßigung des Ölstandes in der Ölwanne insbesondere während Kurvenfahrten des Kraftfahrzeuges bewirken. Die Rippen können in an sich bekannter Weise nahe der Umlaufbahn der Kurbeln der Kurbelwelle liegen, um die Wirbelbildung in der Ölwanne zu verringern.Another preferred embodiment the oil pan according to the invention in that the multilayer part has one or more holes or Has recesses on which one or more protruding into the oil pan Ribs form-fitting are attached. The respective ribs are made in one step with the oil pan in same injection mold formed. The positive connection between the ribs and the multi-layer part is realized via holes in the multi-layer part. The ribs have the function of oil surge ribs, which equalize the oil level in the oil pan especially during Cause cornering of the motor vehicle. The ribs can be in in a known manner near the orbit of the cranks of the crankshaft to reduce the swirl formation in the oil pan.
