Abstract
Description
Die Erfindung betrifft ein Strukturbauteil für eine Fahrzeugkarosserie nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a structural component for a vehicle body according to the preamble of
Aus dem Stand der Technik sind Kraftfahrzeuge mit Fahrzeugkarosserien bekannt, bei denen an einem Bauteil der Fahrzeugkarosserie, insbesondere einem Leiterrahmen oder einem Längsträger Strukturbauteile befestigt sind. Das Strukturbauteil weist eine konusförmige äußere Struktur auf und ist seitlich und insbesondere beidseitig an einem Längsträger befestigt. Bei einer Kollision des Kraftfahrzeugs wird das konusförmige Strukturbauteil deformiert, um so einen Teil eines auf das Kraftfahrzeug einwirkenden kollisionsbedingten Energieeintrags zu absorbieren.Motor vehicles with vehicle bodies are known from the prior art, in which structural components are fastened to a component of the vehicle body, in particular a ladder frame or a longitudinal member. The structural component has a cone-shaped outer structure and is attached laterally and in particular on both sides to a longitudinal carrier. In a collision of the motor vehicle, the cone-shaped structural component is deformed so as to absorb part of a collision-induced energy input acting on the motor vehicle.
Aus der
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, ein verbessertes Strukturbauteil für eine Fahrzeugkarosserie anzugeben, mittels dessen insbesondere eine kollisionsbedingte Deformation einer Fahrgastzelle vermeidbar ist.Based on this prior art, it is an object of the invention to provide an improved structural component for a vehicle body, by means of which in particular a collision-induced deformation of a passenger compartment is avoidable.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Strukturbauteil für eine Fahrzeugkarosserie weist ein durch einen äußeren Mantel begrenztes Hohlraumprofil auf, das eine Vielzahl von Hohlräumen umfasst.A structural body for a vehicle body has a cavity defined by an outer shell cavity profile comprising a plurality of cavities.
Erfindungsgemäß weist das Strukturbauteil einen über eine axiale Länge gleich bleibenden Querschnitt auf, der eine verjüngende Kontur aufweist.According to the invention, the structural component has a cross-section which remains constant over an axial length and has a tapering contour.
Mittels der verjüngenden Kontur des erfindungsgemäßen Strukturbauteils können punktuell auftretende Lasten großflächig im Strukturbauteil und insbesondere über die axiale Länge des Strukturbauteils verteilt werden und somit mehr Energie im Strukturbauteil aufgenommen und/oder absorbiert werden. Dabei wird insbesondere das Strukturbauteil über die axiale Länge deformiert. Das innere Hohlraumprofil des Strukturbauteils und ein innerhalb des Hohlraums angeordneter Einleger begünstigt dabei in besonders vorteilhafter Weise die Umverteilung eines auf das Strukturbauteil einwirkenden Energieeintrags.By virtue of the tapered contour of the structural component according to the invention, loads which occur at certain points can be distributed over a large area in the structural component and in particular over the axial length of the structural component, and thus more energy can be absorbed and / or absorbed in the structural component. In particular, the structural component is deformed over the axial length. The inner cavity profile of the structural component and a liner arranged inside the cavity thereby favor the redistribution of an energy input acting on the structural component in a particularly advantageous manner.
Eine Wandstärke des äußeren Mantels nimmt entlang der transversalen Richtung von einer Basislinie zu einem verjüngten Konturenende des Strukturbauteils ab. Dabei wird eine progressive Kennlinie zur kontrollierten Deformation des Strukturbauteils gebildet: Der auf das Strukturbauteil einwirkende Energieeintrag wird in Abhängigkeit von dessen Größe innerhalb des Strukturbauteils mittels geleisteter Deformationsarbeit absorbiert. Dabei kann ein kleiner Energieeintrag in einem Bereich des Strukturbauteils nahe des verjüngtem Konturenendes vollständig absorbiert werden. Erst bei größeren einwirkenden Energieeinträgen werden die dahinter liegenden Strukturen des Strukturbauteils in Richtung der Basislinie deformiert. Damit ist insbesondere eine unnötige Deformation des gesamten Strukturbauteils bei kleinen Energieeinträgen vermeidbar.A wall thickness of the outer shell decreases along the transverse direction from a baseline to a tapered contour end of the structural member. In this case, a progressive characteristic for the controlled deformation of the structural component is formed: The energy input acting on the structural component is absorbed as a function of its size within the structural component by means of deformation work performed. In this case, a small energy input in a region of the structural component near the tapered contour end can be completely absorbed. Only with larger acting energy inputs are the underlying structures of the structural component deformed in the direction of the baseline. In particular, an unnecessary deformation of the entire structural component with small energy inputs can be avoided.
Das Strukturbauteil ist dabei vorteilhafter Weise aus jedem geeigneten Material ausbildbar, vorzugsweise als ein einteiliges Strukturbauteil aus einem Faserverbundmaterial z. B. mittels eines Pultrusionsverfahrens hergestellt oder aber alternativ aus einem metallischen Material z. B. mittels eines Strangpressverfahrens hergestellt. In weiterer alternativer Ausgestaltung ist es möglich das Strukturbauteil mehrteilig auszubilden, vorzugsweise mittels eines geschäfteten Aufbaus, welcher durch das Ineinanderstecken von mehreren (Hut-)Profilen in transversaler Richtung gebildet ist, wobei die Profile kraft-, form- und/oder stoffschlüssig miteinander verbunden sind.The structural component is advantageously formed from any suitable material, preferably as a one-piece structural component of a fiber composite material z. B. produced by means of a pultrusion process or alternatively from a metallic material z. B. produced by means of an extrusion process. In a further alternative embodiment, it is possible to form the structural component in several parts, preferably by means of a buried structure which is formed by the nesting of several (hat) profiles in the transverse direction, wherein the profiles are positively, positively and / or materially connected to each other ,
Das Strukturbauteil ist vorteilhafter Weise an einem über die axiale Länge erstreckenden Bereich eines insbesondere länglichen Bauteils einer Fahrzeugkarosserie, beispielsweise einem Schweller und/oder einem Längsträger befestigt. Dabei erhöht das Strukturbauteil eine Verformungssteifigkeit des Bauteils der Fahrzeugkarosserie über den entlang der axialen Länge erstreckenden Bereich. Dadurch ist eine Deformation einer Fahrgastzelle insbesondere bei einem räumlich stark lokalisierten und/oder punktuell auftretenden Aufprall eines Kraftfahrzeugs vermeidbar.The structural component is advantageously fastened to a region of a vehicle body, in particular a longitudinal member, extending over the axial length, for example a sill and / or a longitudinal member. In this case, the structural component increases a deformation rigidity of the component of the vehicle body over the region extending along the axial length. As a result, a deformation of a passenger compartment can be avoided, in particular in the case of a spatially highly localized and / or punctually occurring impact of a motor vehicle.
