Abstract
Description
Die Erfindung betrifft eine Rahmenvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a frame device according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine besonders vorteilhafte Rahmenvorrichtung bereitzustellen, die insbesondere ein vorteilhaftes Gewicht und eine vorteilhafte Steifigkeit aufweist. Sie wird durch eine erfindungsgemäße Rahmenvorrichtung entsprechend dem Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of providing a particularly advantageous frame device, which in particular has an advantageous weight and advantageous stiffness. It is achieved by a frame device according to the invention according to claim 1. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einer Rahmenvorrichtung für ein Nutzfahrzeug, die zumindest einen einstückig, als separates Bauteil ausgebildeten Frontquerträger aufweist, der in montiertem Zustand dazu vorgesehen ist, einen ersten Längsträger und einen zweiten Längsträger in einer Front des Nutzfahrzeugs miteinander zu verbinden.The invention relates to a frame device for a commercial vehicle, which has at least one integrally formed as a separate component front cross member, which is provided in the assembled state to connect a first side member and a second side member in a front of the utility vehicle with each other.
Es wird vorgeschlagen, dass der Frontquerträger zur Versteifung zumindest in einem Bereich eine Wabenstruktur ausbildet. Dadurch kann der Frontquerträger besonders vorteilhaft und insbesondere mit einem besonders vorteilhaften Gewicht bei einer besonders vorteilhaften Steifigkeit bereitgestellt werden, wodurch die Rahmenvorrichtung insbesondere vorteilhaft ausgebildet werden kann. Unter „einstückig, als separates Bauteil ausgebildet” soll dabei insbesondere verstanden werden, dass der Frontquerträger als ein einziges, alleinstehendes Bauteil ausgebildet ist, das während eines Montagevorgangs, vorzugsweise mittels Schraubverbindungen, fest mit den Längsträgern verbunden wird. Dabei können grundsätzlich weitere Anbauteile, wie Beispielsweise eine Beleuchtung, Halterungen und/oder andere, dem Fachmann als sinnvoll erscheinende Anbauteile an den Frontquerträger angebunden werden. Der Frontquerträger ist dabei insbesondere nicht als ein aus einem oder mehreren Elementen bestehendes Schweißbauteil ausgebildet, das über eine Schweißverbindung mit den Längsträgern verbunden ist. Unter „vorgesehen” soll insbesondere speziell ausgelegt und/oder ausgestattet verstanden werden. Unter einer „Wabenstruktur” soll dabei insbesondere eine Struktur aus aneinander angrenzenden, von Rippen gebildeten, geschlossenen Waben verstanden werden, wobei aneinander angrenzende Waben zumindest teilweise von den selben Rippen ausgebildet werden. Dabei weisen die Waben vorzugsweise eine viereckige Grundform auf, wobei es grundsätzlich auch denkbar ist, dass die Waben eine andere, dem Fachmann als sinnvolle erscheinende Grundform, wie beispielsweise eine sechseckige Grundform, aufweisen.It is proposed that the front cross member forms a honeycomb structure for stiffening at least in one area. Thereby, the front cross member can be provided particularly advantageous and in particular with a particularly advantageous weight with a particularly advantageous rigidity, whereby the frame device can be formed particularly advantageous. By "in one piece, designed as a separate component" is to be understood in particular that the front cross member is formed as a single, stand-alone component, which is connected during an assembly operation, preferably by means of screw, fixed to the side rails. In principle, further attachments, such as lighting, brackets and / or other, the skilled person appear useful attachments to the front cross member can be connected. The front cross member is in particular not designed as a welding component consisting of one or more elements, which is connected to the side members via a welded connection. By "intended" is intended to be understood in particular specially designed and / or equipped. A "honeycomb structure" is to be understood in particular as meaning a structure of adjoining, closed honeycombs formed by ribs, wherein adjacent honeycombs are at least partially formed by the same ribs. In this case, the honeycombs preferably have a quadrangular basic shape, wherein it is basically also conceivable that the honeycombs have another basic form which appears to the person skilled in the art as meaning, for example, a hexagonal basic shape.
Weiter wird vorgeschlagen, dass der Frontquerträger in zumindest einem Teilbereich eine parallel zu einer Haupterstreckungsrichtung verlaufende dünnwandige Platte ausbildet, auf der die Wabenstruktur beidseitig angeordnet ist. Dadurch kann der Frontquerträger besonders Steif ausgebildet werden. Unter „beidseitig angeordnet” soll dabei insbesondere verstanden werden, das auf beiden orthogonal zur Haupterstreckungsrichtung stehenden Seitenflächen der Platte eine Wabenstruktur angeordnet ist.It is further proposed that the front cross member forms in at least one subregion a thin-walled plate running parallel to a main extension direction, on which the honeycomb structure is arranged on both sides. As a result, the front cross member can be made particularly stiff. The term "arranged on both sides" is to be understood in particular as meaning that a honeycomb structure is arranged on both lateral surfaces of the plate orthogonal to the main extension direction.
Zudem wird vorgeschlagen, dass in die dünnwandige Platte zumindest ein Durchgangsloch eingebracht ist, das dazu vorgesehen ist, während einer Fahrt des Nutzfahrzeugs ein Strömen eines Luftstroms durch den Frontquerträger zu ermöglichen. Dadurch kann der Frontquerträger insbesondere so ausgestaltet werden, dass er einem Luftstrom, vorzugsweise einem Fahrtwind, wenig Widerstand leistet und der Luftstrom so besonders vorteilhaft und ohne größere Verluste zu einem Kühler einer Brennkraftmaschine des Nutzfahrzeugs gelangen kann.In addition, it is proposed that at least one through hole is provided in the thin-walled plate, which is intended to allow a flow of air flow through the front cross member during a ride of the commercial vehicle. As a result, the front cross member can be configured in particular so that it provides little resistance to an air flow, preferably a wind, and the air flow can thus reach the cooler of an internal combustion engine of the commercial vehicle so particularly advantageously and without major losses.
Weiterhin wird vorgeschlagen, dass der Frontquerträger als ein Gussbauteil ausgebildet ist. Dadurch kann der Frontquerträger besonders einfach hergestellt werden. Unter einem „Gussbauteil” soll dabei insbesondere ein Bauteil verstanden werden, das in einem formgebenden Gießverfahren hergestellt ist.Furthermore, it is proposed that the front cross member is formed as a cast component. As a result, the front cross member can be made particularly easy. In this context, a "cast component" is to be understood in particular as meaning a component which is produced in a shaping casting process.
Weitere Vorteile ergeben sich aus der folgenden Figurenbeschreibung. In den Figuren ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Figuren, die Figurenbeschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages will become apparent from the following description of the figures.
