Es ist Aufgabe der Erfindung, ein alternatives Profilbauteil der eingangs genannten Art zu schaffen.It Object of the invention, an alternative profile component of the above to create said type.
Zur Lösung der Aufgabe wird ein Profilbauteil mit den Merkmalen des Anspruchs 1 vorgeschlagen. Das erfindungsgemäße Profilbauteil zeichnet sich dadurch aus, dass die Strukturierung bei einer steifigkeitsverringernden Kontur durch eine geometrische Oberflächenstruktur gebildet ist, und dass die Strukturierung bei einer steifigkeitserhöhenden Kontur durch eine Ausnehmungsstruktur und/oder durch eine zu einer Profilgrundwandstärke verkleinerte Wandstärke gebildet ist. Hierdurch ist es möglich, ein in Profillängsrichtung an die jeweils zu erwartende Beanspruchungshöhe und/oder -art angepasst konzipiertes Profilbauteil zu schaffen, wobei das Profilbauteil in Profillängsrichtung nun auch unterschiedliche Konturen enthalten kann, welche ohne eine geeignete Strukturierung des Profilbauteils eine Steifigkeitsveränderung in Profillängsrichtung hervorrufen würden. Eine derartige steifigkeitsverändernde Kontur kann beispielsweise im Fahrzeugbau zur Optimierung der Bauraumausnutzung erstrebenswert bzw. erforderlich sein. Mittels einer geeigneten, die Steifigkeitsverände rung wenigstens teilweise kompensierenden Strukturierung des Profilbauteils ist es möglich zu gewährleisten, dass selbiges eine hinreichend große Steifigkeit aufweist und gleichzeitig eine konstruktiv flexible Profilbauteilstrukturierung, ggf. unter Berücksichtigung von Leichtbaukonzepten, möglich ist. Mittels einer derartigen steifigkeitserhöhenden bzw. steifigkeitsverringernden Strukturierung mindestens eines Profilschenkels des Profilbauteils ist es möglich, selbiges auf vielseitige Weise an die jeweils vorliegenden Einbau- und/oder Beanspruchungsanforderungen, beispielsweise in einer Fahrzeugkarosserie, anzupassen.to solution The object is a profile component with the features of the claim 1 proposed. The profile component according to the invention is characterized from that structuring at a stiffness-reducing Contour is formed by a geometric surface texture, and that the structuring with a stiffness-increasing contour through a recess structure and / or formed by a wall thickness reduced to a profile base wall thickness is. This makes it possible one in profile longitudinal direction adapted to the respective expected level of stress and / or type to create a designed profile component, wherein the profile component in profile longitudinal direction now can also contain different contours, which without a suitable structuring of the profile component a change in stiffness in profile longitudinal direction would cause. Such a stiffness-modifying For example, contour can be used in vehicle construction to optimize space utilization be desirable or required. By means of a suitable, the stiffness changes at least partially compensating structuring of the profile component Is it possible to ensure, that the same has a sufficiently high rigidity and at the same time structurally flexible profile component structuring, if necessary under consideration lightweight concepts, is possible. By means of such a stiffness-increasing or stiffness-reducing Structuring of at least one profile limb of the profile component Is it possible, the same in a versatile manner to the respective installation and / or stress requirements, for example, in a vehicle body, adapt.
Die geometrische Oberflächenstruktur kann beispielsweise als mindestens eine Sicke ausgebildet sein. Die Ausnehmungsstruktur kann z. B. als mindestens eine Profilwandöffnung ausgebildet sein. Eine derartige Profilwandöffnung kann mittels einer Ausstanzung fertigungstechnisch verhältnismäßig einfach realisiert werden. Ferner kann die Profilwandöffnung ggf. mit einem flanschartigen Rand versehen sein. Derartige konstruktive Maßnahmen der Profilstrukturierung sind verhältnismäßig einfach an Walzprofilen realisierbar.The geometric surface structure may be formed, for example, as at least one bead. The recess structure can, for. B. formed as at least one profile wall opening be. Such a profile wall opening can production technology relatively simple by means of a punched will be realized. Furthermore, the profile wall opening, if necessary, with a flange Be provided edge. Such structural measures of profile structuring are relatively easy realized on rolled sections.
Die Strukturierung kann innerhalb eines vollständigen Profillängsteilbereichs oder auch in einem Teilsektor eines Profillängsteilbereichs ausgebildet sein. Bei einem derartigen Teilsektor handelt es sich um einen, sich lediglich teilweise in Umfangsrichtung erstreckenden Sektor innerhalb eines Profillängsteilbereichs. Unter einem vollständigen Profillängsteilbereich wird somit ein Teilbereich verstanden, der sich über den kompletten Umfang des Profilbauteils erstreckt.The Structuring can be done within a complete profile range or also be formed in a subsector of a profile longitudinal section. Such a subsector is one that only partially circumferentially extending sector within one Profile longitudinal portion. Under a complete Profile longitudinal portion Thus, a sub-area is understood that extends over the entire scope of Profile component extends.
Das Profilbauteil kann ein Hohlprofil mit in Längsrichtung variierender Profilhöhe und/oder Profilbreite sein. Hierdurch wird bei Gewährleistung einer hinreichend großen Profilstei figkeit eine verhältnismäßig hohe Gestaltungsflexibilität in Bezug auf die Konstruktion von Profilbauteilen geschaffen.The Profile component may be a hollow profile with varying profile length in the longitudinal direction and / or Be profile width. This is sufficient to ensure a sufficient huge Profile stiffness a relatively high design flexibility created in relation to the construction of profile components.
Gemäß einer möglichen Ausführungsform enthält das Hohlprofil ein im Querschnitt im Wesentlichen U-förmiges Walzprofil, an dessen freien Enden ein Walzblech schweißbefestigt ist, unter Ausbildung eines geschlossenen Hohlprofils. Dabei kann die Strukturierung beispielsweise im Walzblech ausgebildet sein.According to a possible embodiment, the hollow profile contains a cross-section in essence union U-shaped rolled section, at the free ends of a rolled sheet is welded, with the formation of a closed hollow profile. In this case, the structuring may be formed, for example, in the rolled sheet.
Die Steifigkeit des Profilbauteils kann in Profillängsrichtung im Wesentlichen konstant sein oder ggf. je nach Belastungsfall definiert variieren. Bei dem Profilbauteil kann es sich um ein Leichtbau-Konstruktionsteil, insbesondere eines Fahrzeugs, handeln.The Rigidity of the profile component can in the profile longitudinal direction substantially be constant or may vary depending on the load case. The profile component may be a lightweight construction part, in particular of a vehicle.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung.Further Advantages of the invention will become apparent from the description.
