Längsträger, insbesondere eines Personenkraf fahrzeugesSide member, in particular a passenger vehicle
Die Erfindung betrifft einen Längsträger, insbesondere eines Personenkraf fahrzeuges, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a side member, in particular a passenger vehicle, according to the preamble of claim 1.
Ein derartiger Längsträger ist aus DE 40 20 363 AI bekannt.Such a longitudinal beam is known from DE 40 20 363 AI.
Die Erfindung beschäftigt sich mit dem Problem, einen gattungsgemäßen Längsträger in einer hochfesten und crashoptimierten Ausführung zu schaffen, der aus einzelnen, sicher, einfach und beständig toleranzfrei herstellbaren Profilen zusammengesetzt werden kann. Bei einer Metallausführung der einzelnen Profile sollen diese durch Schweißen zu gattungsgemäßen Längsträgern miteinander verbunden werden können.The invention is concerned with the problem of creating a generic side member in a high-strength and crash-optimized design, which can be assembled from individual, safe, simple and stable tolerance-free profiles. If the individual profiles are made of metal, they should be able to be connected to one another by welding to form longitudinal members of the generic type.
Gelöst wird dieses Problem in erster Linie durch eine Ausbildung eines gattungsgemäßen Längsträgers nach dem kennzeichnenden Merkmal des Patentanspruchs 1.This problem is solved primarily by designing a generic longitudinal member according to the characterizing feature of patent claim 1.
Vorteilhafte und zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous and expedient embodiments of the invention are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, ein im Inneren eines geschlossenen Längsträgeraußenprofils liegendes Verstärkungsprofil geteilt auszubilden, um dieses einfach to- leranzfrei herstellen und spannungsfrei mit den Außenprofilen verbinden zu können.The invention is based on the general idea of dividing a reinforcement profile lying inside a closed longitudinal member outer profile in order to simply Manufacturing without any tolerance and being able to connect to the external profiles without tension.
Durch die erfindungsgemäße Zusammensetzung eines gattungsgemäßen Längsträgers aus einfach geformten Einzelprofilen können insbesondere ultrahochfeste Werkstoffe für einen hinteren Längsträger eingesetzt werden. Als Fertigungsverfahren für einzusetzende Metallbleche kommen für die einzelnen Profile eine Warmumformung ebenso wie eine konven ionelle Umformtechnik in Frage, da der erfindungsgemäße Aufbau der hinteren Längsträgerstruktur auf einem fertigungs- und toleranzgerechten Ansatz beruht. Die einzelnen aus Blech bestehenden Profile werden insbesondere durch Schweißen miteinander verbunden.Due to the composition according to the invention of a generic side member of simply shaped individual profiles, in particular ultra high-strength materials can be used for a rear side member. As a manufacturing process for metal sheets to be used, hot forming as well as a conventional ion forming technique are possible for the individual profiles, since the structure of the rear side member structure according to the invention is based on a manufacturing and tolerance-oriented approach. The individual profiles made of sheet metal are connected to one another in particular by welding.
Die erfindungsgemäß günstigen Formen und Zusammensetzungen der einzelnen Profile sind in den Unteransprüchen jeweils konkret angegeben und werden nachstehend noch näher erläutert werden.The forms and compositions of the individual profiles which are favorable according to the invention are each specifically specified in the subclaims and will be explained in more detail below.
Besonders vorteilhafte Ausführungsbeispiele sind in der Zeichnung jeweils schematisch dargestellt.Particularly advantageous exemplary embodiments are each shown schematically in the drawing.
In dieser zeigen:In this show:
Fig. 1 - 3 Querschnitte eines hinteren Längsträges in drei verschiedenen Ausführungsformen jeweils mit einer Schnittführung durch die Mitte eines Kraftfahrzeug-Hinterrades .Fig. 1-3 cross sections of a rear longitudinal beam in three different embodiments, each with a cut through the middle of a motor vehicle rear wheel.
Ein als Hohlprofil ausgebildeter Längsträger nach Fig. 1 um- fasst ein U-förmiges ersten Außenprofil 1, ein inneres Verstärkungsprofil 2 sowie ein das äußere U-förmige erste Außenprofil 1 verschließendes Schließteil 3, wobei zwischen dem Schließteil 3 und dem U-förmigen ersten Außenprofil 1 noch zusätzlich ein Radeinbauelement 4 liegt.1 comprises a U-shaped first outer profile 1, an inner reinforcing profile 2 and a closing part 3 which closes the outer U-shaped first outer profile 1, whereby between the Locking part 3 and the U-shaped first outer profile 1 is also a wheel installation element 4.
Die Lage eines solchen hohlen Längsträgers innerhalb eines Fahrzeuges ist in den einzelnen Figuren jeweils mit einem x- y-z-Achsenkreuz angegeben. Dabei bedeuten x die Längsachse des Fahrzeuges, z die Richtung in Hochachse des Fahrzeuges und Y die Fahrzeugquerrichtung.The position of such a hollow longitudinal member within a vehicle is indicated in the individual figures with an x, y, z axis cross. Here, x is the longitudinal axis of the vehicle, z is the direction in the vertical axis of the vehicle and Y is the transverse direction of the vehicle.
Der aus den vorgenannten Profilteilen 1 bis 4 zusammengesetzte Längsträger ist in Richtung zur Fahrzeuginnenseite mit einem Bodenelement 5 des Fahrzeuges verschweiß .The longitudinal member composed of the aforementioned profile parts 1 to 4 is welded in the direction of the inside of the vehicle to a floor element 5 of the vehicle.
Bei einer vorzugsweisen Ausbildung der einzelnen Profilteile 1 bis 4 sowie des Bodens 5 aus Metall sind diese Bauelemente zu einer integrierten Tragstruktur miteinander verschweißt.In a preferred embodiment of the individual profile parts 1 to 4 and the base 5 made of metal, these components are welded together to form an integrated support structure.
Auch die Verbindung des Längsträgers mit dem Fahrzeug- Bodenelement 5 ist eine insoweit übliche Schweißverbindung.The connection of the side member to the vehicle floor element 5 is also a common welded connection.
Bei der Ausführung nach Fig. 1 setzt sich das innere Verstärkungsprofil 2 aus zwei Einzelprofilen 6 und 7 zusammen, wobei diese Einzelprofile 6, 7 jeweils die Form eines Doppelwinkels aufweisen.In the embodiment according to FIG. 1, the inner reinforcement profile 2 is composed of two individual profiles 6 and 7, these individual profiles 6, 7 each having the shape of a double angle.
Jedes dieser beiden Einzelprofile S besitzt einen mittleren Bereich 8, sowie hiervon jeweils senkrecht abgewinkelte Winkelstege 9, nämlich einen ersten, nach außen führenden Winkelsteg 9 und einen zweiten, ausschließlich im Inneren des hohlen Längsträgers liegenden zweiten Winkelsteg 10. Der mittlere Bereich 8 liegt jeweils parallel an dem jeweils zugeordneten U-Schenkel des U-förmigen ersten Außenprofiles 1 an. Aus dem Inneren des U-förmigen ersten Außenprofils 1 rechtwinklig nach außen abragend verläuft der jeweilige erste Winkelsteg 9 für eine parallele Anlage an dem Schließteil 3, wobei das Radeinbauelement 4 von dem jeweiligen ersten Winkelsteg 9 und dem Schließteil 3 zwischen sich eingeschlossen wird.Each of these two individual profiles S has a central region 8, as well as angular webs 9 which are angled perpendicularly from it, namely a first angular web 9 leading to the outside and a second second angular web 10 lying exclusively in the interior of the hollow longitudinal beam. The central region 8 is in each case parallel on the respectively assigned U-leg of the U-shaped first outer profile 1. The respective first extends from the inside of the U-shaped first outer profile 1 at right angles to the outside Angular web 9 for parallel contact with the closing part 3, the wheel installation element 4 being enclosed between them by the respective first angular web 9 and the closing part 3.
Die zweiten Winkelstege 10 der Einzelprofile 6, 7 sind jeweils derart geformt, dass sie überlappend gegeneinander zu liegen kommen und zwischen sich einen Zusatzhohlraum 11 ausbilden.The second angular webs 10 of the individual profiles 6, 7 are each shaped such that they overlap one another and form an additional cavity 11 between them.
Die Ausführung nach Fig. 2 unterscheidet sich von derjenigen nach Fig. 1 lediglich durch den Aufbau des inneren Verstärkungsprofils 2 , das in Fig. 2 mit 2' bezeichnet ist. Die den Einzelprofilen 6 und 7 des inneren Verstärkungsprofiles 2 nach Fig. 1 in Fig. 2 entsprechenden Einzelprofile des inneren Verstärkungsträgers 2 sind dort mit den Bezugszeichen β' und 7' belegt. Bei dieser Ausführung nach Fig. 2 führen die innen liegenden zweiten Winkelstege zu keiner gegenseitigen Überlappung. Diese zweiten Winkelstege, die dort als Verbindungsstege 10' bezeichnet sind, liegen lediglich in einer gemeinsamen Ebene, jedoch voneinander beabstandet. Der Abstand zwischen den Winkelstegen 10' wird von einem zusätzlichen Einzelprofil 12 überbrückt, wobei dieses Einzelprofil 12 mit den Winkelstegen 10' fest verbunden ist, d.h. verschweißt ist .The embodiment according to FIG. 2 differs from that according to FIG. 1 only in the construction of the inner reinforcement profile 2, which is designated 2 ′ in FIG. 2. The individual profiles of the inner reinforcing beam 2 corresponding to the individual profiles 6 and 7 of the inner reinforcing profile 2 according to FIG. 1 in FIG. 2 are given the reference symbols β 'and 7' there. In this embodiment according to FIG. 2, the second angular webs on the inside do not overlap each other. These second angular webs, which are referred to there as connecting webs 10 ′, lie only in a common plane, but are spaced apart from one another. The distance between the angular webs 10 'is bridged by an additional individual profile 12, this individual profile 12 being firmly connected to the angular webs 10', i.e. is welded.
Möglich ist es auch, die Einzelprofile 6' und 7' im Inneren des U-förmigen ersten Außenprofiles 1 bei der Ausführung nach Fig. 2 nicht zu trennen, das heißt als ein einteiliges, die Einzelprofil 6', 7' umfassendes Innenprofil mit einem gemeinsamen U-Rücken 10' als zweiten Winkelsteg auszubilden. Diese Ausführung ist in der Fig. 2 strichpunktiert angedeutet. Bei dieser Ausführung entsteht wiederum zwischen dem Einzelprofil 12 und dem die Bereiche 6', 7' und 10' umfassenden Innenprofil ein Zusatzhohlräum 11 wie bei der Ausführung nach Fig. 1,It is also possible not to separate the individual profiles 6 'and 7' inside the U-shaped first outer profile 1 in the embodiment according to FIG. 2, that is to say as a one-piece inner profile comprising the individual profiles 6 ', 7' with a common one Form U-back 10 'as a second angled web. This embodiment is indicated by dash-dotted lines in FIG. 2. In this version, there is again between the individual profile 12 and the inner profile comprising the areas 6 ', 7' and 10 'an additional cavity 11 as in the embodiment of FIG. 1,
Die Ausführung nach Fig. 3 ist mit derjenigen nach Fig. 1 vergleichbar und unterscheidet sich von dieser lediglich dadurch, dass das U-förmige erste Außenprofil 1 dort aus zwei winkelförmig gestalteten Einzelelementen 13 und 14 zusammengesetzt ist, wobei diese Form des ersten Außenprofils 1 mit dem Bezugszeichen 1' belegt ist. 3 is comparable to that of FIG. 1 and differs from it only in that the U-shaped first outer profile 1 is composed of two angularly shaped individual elements 13 and 14, this shape of the first outer profile 1 with the reference symbol 1 '.
