Abstract
Description
Die
Erfindung betrifft ein Karosserieteil für ein Kraftfahrzeug, mit einem
aus einem spröden Werkstoff,
insbesondere Leichtmetall-Sandguss, bestehenden Verbindungsteil,
nach der im Oberbegriff von Anspruch 1 näher definierten Art.The
The invention relates to a body part for a motor vehicle, with a
made of a brittle material,
in particular light metal sand casting, existing connecting part,
according to the closer defined in the preamble of
Bei Karosserien von Kraftfahrzeugen werden häufig Profil-, Guss- und Blechbauteile so miteinander kombiniert und verbunden, dass sie im Crashfall gute Steifigkeitseigenschaften aufweisen. Hierzu ist es sinnvoll, in besonders hoch belasteten Bereichen Profilbauteile einzusetzen, da diese aufgrund ihrer Duktilität die Anforderungen an das Crashverhalten erfüllen, wohingegen Gussbauteile, die eine geringere Duktilität aufweisen, üblicherweise in den Karosseriebereichen eingesetzt werden, in denen geringere Crashanforderungen bestehen. Solche, eine geringere Steifigkeit im Crashfalls aufweisenden Gussbauteile werden eingesetzt, da sie hinsichtlich der Integration verschiedenster Funktionen Vorteile bieten, die sich insbesondere dadurch ergeben, dass sie mit verhältnismäßig geringem Aufwand so ausgeführt werden können, dass mehrere andere Bauteile, beispielsweise Fahrwerkskomponenten und dergleichen, an den Gussbauteilen angebracht werden können.at Automotive bodywork often becomes tread, cast and sheet metal components so combined and connected together that they are good in the event of a crash Have stiffness properties. For this it makes sense in particularly heavy duty areas to use profile components, because these are due to their ductility meet the requirements for crash behavior, whereas cast components, the lower ductility usually be used in the bodywork areas where lower Crash requirements exist. Such, a lower rigidity in case of a crash having cast components are used because they in terms of integration of various functions benefits that result in particular from the fact that they Expense to be executed can, that several other components, such as suspension components and the like, can be attached to the cast components.
Da bei bestimmten Karosseriestrukturen die aus Profilen bestehenden Längsträger aufgrund von Design- und Bauraumanforderungen teilweise keine ausreichende duktile Crashlänge bieten können, werden in diesen Bereichen häufig Druckgussbauteile eingesetzt, da deren Duktilität zwar schlechter ist als diejenige von Profilbauteilen, jedoch besser als die Duktilität von Sandgussteilen, die aus fertigungstechnischen Gründen im Falle der Verwendung von Leichtmetall, wie z. B. Aluminium, häufig aus einem sehr spröden Werkstoff bestehen. Aufgrund der für ihre Herstellung notwendigen Gießform und der sich dadurch ergebenden, relativ hohen Kosten können Druckgussbauteile jedoch erst bei Fahrzeugen mit hoher Stückzahl ökonomisch eingesetzt werden.There for certain body structures, which consist of profiles Side member due of design and space requirements sometimes insufficient ductile crash length can offer in these areas frequently Die cast components used, since their ductility is worse than that profile components, but better than the ductility of sand castings, for manufacturing reasons in the case of using light metal, such as. As aluminum, often from a very brittle one Material exist. Due to the necessary for their production mold and the resulting relatively high cost may be die-cast components However, only be used economically in vehicles with high quantities.
Daher muss bei Fahrzeugen, die voraussichtlich nur in geringen Stückzahlen gebaut werden, aus Kostengründen teilweise auf die Verwendung von Sandgussteilen zurückgegriffen werden, was aufgrund der Sprödigkeit dieses Werkstoffs zu einem unbefriedigenden Crashverhalten führt. Es ergibt sich in solchen Fällen also ein Zielkonflikt aufgrund der hohen Kosten von Druckgussbauteilen und des schlechten Crashverhaltens von Sandgussbauteilen.Therefore Must be in vehicles that are expected to be low in numbers be built, for cost reasons partly resorting to the use of sand castings which is due to the brittleness This material leads to an unsatisfactory crash behavior. It arises in such cases So a conflict of objectives due to the high cost of die-cast components and the bad crash behavior of sand cast components.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Karosserieteil für ein Kraftfahrzeug zu schaffen, welches eine hohe Steifigkeit aufweist und auch in geringen Stückzahlen rentabel hergestellt werden kann.It is therefore an object of the present invention, a body part for a To provide motor vehicle, which has a high rigidity and also in small quantities can be produced profitably.
Erfindungsgemäß wird diese
Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this
Problem solved by the features mentioned in
Durch die erfindungsgemäße Kombination eines eine höhere Duktilität aufweisenden Einlegeteils mit dem aus Leichtmetall-Sandguss bestehenden Verbindungsteil kann durch den Verzicht auf Druckgussbauteile das erfindungsgemäße Karosserieteil auch dann kostengünstig hergestellt werden, wenn es bei Kraftfahrzeugen mit geringeren Stückzahlen zum Einsatz kommen soll, wobei durch das Einlegeteil die Duktilität des Verbindungsteils und somit des gesamten Karosserieteils erheblich erhöht wird, so dass das gesamte Karosserieteil im Crashfall die notwendige Strukturintegrität besitzt. Vorteilhafterweise wird selbst bei größeren Deformationen, bei denen das aus dem Sandguss bestehende Verbindungsteil festigkeitsmäßig versagt, durch das Einlegeteil die notwendige Steifigkeit erreicht.By the inventive combination of a higher one ductility having insert with the existing of light metal sand casting Connecting part can by dispensing with die cast components Body part according to the invention even then cost be made when it comes to motor vehicles with smaller quantities is to be used, wherein by the insert the ductility of the connecting part and thus the entire body part is considerably increased, so that the entire body part has the necessary structural integrity in the event of a crash. Advantageously, even with larger deformations in which the connecting part made of the sand casting fails in terms of strength, achieved by the insert the necessary rigidity.
Der Vorteil der durch die erfindungsgemäßen Lösung möglich gemachten Verwendung eines aus Leichtmetall-Sandguss bestehenden Verbindungsteils in einer Karosserie besteht des weiteren darin, dass an dieses Teil die verschiedensten weiteren Bauteile des Kraftfahrzeugs angebracht werden können, wie beispielsweise Fahrwerkskomponenten oder weitere Karosserieteile, da ein solches Gussteil sehr einfach mit den entsprechenden Anschlüssen, Flanschen und dergleichen versehen werden kann.Of the Advantage of the use made possible by the inventive solution a made of light metal sand casting connecting part in a body is further that in this part the various other components of the motor vehicle mounted can be such as suspension components or other body parts, because such a casting very easy with the corresponding connections, flanges and the like can be provided.
Um die Steifigkeit des erfindungsgemäßen Karosserieteils weiter zu erhöhen, kann in einer sehr vorteilhaften Weiterbildung der Erfindung vorgesehen sein, dass an dem Verbindungsteil oder an einem mit dem Verbindungsteil verbundenen Bauteil eine Abstützung für das Einlegeteil angebracht ist, an welchem das Einlegeteil sich zumindest mittelbar abstützt.Around the rigidity of the body part according to the invention on to increase, can be provided in a very advantageous embodiment of the invention be that at the connecting part or at one with the connecting part connected component a support for the Inserted part is attached, on which the insert at least indirectly supported.
Des weiteren kann eine vorteilhafte Ausgestaltung der Erfindung darin bestehen, dass das Verbindungsteil über wenigstens einen Teil seiner Länge einen im Wesentlichen U-förmigen Querschnitt aufweist, wobei das Einlegeteil in einer Ausnehmung zwischen den Schenkeln des U-förmigen Querschnitts angeordnet ist. Dadurch ist einerseits eine einfache Konstruktion gegeben, da das Einlegeteil sehr einfach an dem Verbindungsteil angebracht werden kann, und es ist des weiteren nur ein verhältnismäßig geringer Raumbedarf für das Karosserieteil erforderlich.Of Another may be an advantageous embodiment of the invention therein exist that the connecting part over at least a part of his Length one essentially U-shaped Cross-section, wherein the insert in a recess between the thighs of the U-shaped Cross section is arranged. This is a simple one Given construction, because the insert is very easy on the connecting part can be attached, and it is further only a relatively smaller Space required for the body part required.
