Es sind bereits eine Vielzahl von Maßnahmen im Bugbereich von Fahrzeugen bekannt, die unter anderem einem verbesserten Fußgängerschutz bei Kollisionen insbesondere im unteren Geschwindigkeitsbereich dienen. So sind an den hinter einer relativ weichen, nachgiebigen Außenhaut (Stoßfängerschürze, Kühlergrill, vorderer Bereich von Frontklappen) liegenden Stoßfänger-Querträger Deformationselemente aus geschäumten Kunststoff oder dünnwandigen Blechprofilen angeordnet, die insbesondere die unteren Extremitäten von Personen vor zu hohen Aufprallkräften bewahren sollen. Abhängig von der Konstruktion des Vorbaues des Kraftfahrzeuges sind aber die Deformationselemente nicht immer optimal zu positionieren.It are already a variety of measures in the bow area of vehicles Among other things, an improved pedestrian protection in collisions especially in the lower speed range. So are to the behind a relatively soft, pliable outer skin (Bumper skirt, grille, Front area of front flaps) lying bumper cross member deformation elements foamed Plastic or thin-walled Sheet metal profiles arranged, in particular the lower extremities of Persons against too high impact forces to preserve. Depending on the construction of the stem of the motor vehicle but are the Deformation elements are not always optimally positioned.
Herkömmliche Fußgängerschutzquerträger sind unterhalb des Stoßfängerquerträgers angeordnet. Insbesondere bei Fahrzeugen mit großen Böschungswinkeln (zum Beispiel SUVs) können allerdings derart angeordnete Fußgängerschutzquerträger aufgrund von Platzmangel nicht verwendet werden.conventional Pedestrian protection crossmember are arranged below the bumper cross member. Especially for vehicles with large slope angles (for example SUVs) can however, such arranged pedestrian protection crossbeam due not be used by lack of space.
Aufgabe der Erfindung ist es, mit baulich einfachen, kostengünstigen Mitteln den Fußgängerschutz bei den gattungsgemäßen Personenkraftfahrzeugen weiter zu verbessern.task The invention is structurally simple, inexpensive Means the pedestrian protection in the generic passenger vehicles continue to improve.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte und besonders zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen angeführt.These Task is according to the invention with the Characteristics of claim 1 solved. Advantageous and special appropriate training The invention are set forth in the subclaims.
Erfindungsgemäß wird vorgeschlagen, dass oberhalb des Querträgers und zwischen der Bugschürze und dem Montageträger ein zusätzliches Deformationselement vorgesehen ist, das sich mit einem Basisteil etwa parallel zur Bugschürze und quer verlaufend erstreckt und das mittelbar oder unmittelbar an den Längsträgern abgestützt ist. Damit gelingt es, mit baulich und montagetechnisch einfachen Mitteln eine noch gleichmäßigere Energieverteilung und Energieabsorption im Bereich des Stoßfängers und der darüber liegenden Bugschürze zu erzielen, wobei dem oberhalb liegenden Deformationselement ein gezieltes Verformungsverhalten aufprägbar ist.According to the invention, it is proposed that above the cross member and between the front apron and the mounting bracket an additional deformation element is provided, with a base part approximately parallel to the front apron and extends transversely extending and that directly or indirectly is supported by the longitudinal members. This makes it possible, with construction and assembly technology simple means an even more uniform energy distribution and energy absorption in the area of the bumper and the overlying front apron to achieve, wherein the above-lying deformation element is a targeted Deformation behavior imposable is.
In besonders vorteilhafter Weise kann das Deformationselement durch ein U-förmig ausgeführtes Profilteil gebildet sein, mit einem quer verlaufenden Basisteil und mit im Wesentlichen im Fahrzeuglängsrichtung nach hinten abragenden Armen, die mittelbar oder unmittelbar an den Längsträgern befestigt sind. Dies ermöglicht eine konstruktiv hervorragend an das geforderte Verformungsverhalten des Fahrzeugbugs anpassbare Integration des zweiten Deformationselementes, mit einer stabilen Krafteinleitung über die Längsträger des Vorbaus.In Particularly advantageously, the deformation element can a U-shaped executed Profile part may be formed, with a transverse base part and protruding rearwardly substantially in the vehicle longitudinal direction Poor, which are attached directly or indirectly to the longitudinal members. This allows a structurally outstanding to the required deformation behavior of the Vehicle bugs customizable integration of the second deformation element, with a stable force transmission via the longitudinal members of the stem.
Des Weiteren kann das Deformationselement ausgehend von der Befestigungsstelle nach vorne oben ansteigend ausgeführt sein, wobei das Basisteil in der Seitenansicht gesehen etwa mittig zwischen der an die Bugschürze anschließenden Frontklappe und dem Querträger positioniert ist und deshalb einen gezielten Kraftverlauf über den gesamten Bereich des Fahrzeugbugs mit der angrenzenden Frontklappe herstellt. Durch die schräg nach vorne oben ausgerichtete Konstruktion werden insbesondere im Bereich der in Fahrzeuglängsrichtung verlaufenden Arme des Deformationselementes gegebenenfalls auftretende Kraftspitzen ausgeschlossen, insbesondere bei einer im Wesentlichen horizontal auftretenden Aufprallrichtung und gegebenenfalls einem Offset-Crash.Of Furthermore, the deformation element, starting from the attachment point be carried out rising upward to the front, wherein the base part seen in the side view approximately midway between the adjoining the front apron front flap and the cross member is positioned and therefore a targeted force course over the entire area of the vehicle bug with the adjacent front flap manufactures. By the oblique forward-facing construction will be especially in Range of extending in the vehicle longitudinal direction Arms of the deformation element possibly occurring force peaks excluded, especially at a substantially horizontal occurring impact direction and optionally an offset crash.
Bevorzugt kann das Deformationselement ferner über an den Armen angeschweißte Platten an Schottblechen befestigt sein, die zwischen den Längsträgern und an dem Querträger befestigten Deformationskonsolen vorgesehen sind. Insbesondere können die Platten mittels Schraubverbindungen lösbar an den Schottblechen befestigt sein.Prefers For example, the deformation element can also be welded to plates welded to the arms be attached to partition plates, between the side rails and on the cross member attached deformation brackets are provided. In particular, the Plates by means of screw detachably attached to the bulkhead plates be.
In fertigungstechnisch besonders einfacher Weise kann das Deformationselement aus einem U-förmig gebogenen Metallrohr definierter Wandstärke und Festigkeit hergestellt sein. Als Werkstoffe kommen den Anforderungen entsprechend sowohl Stahl aus auch Leichtmetalle in Betracht. Gegebenenfalls können aber auch andere, offene Profile für das Deformationselement verwendet sein.In manufacturing technology particularly simple way, the deformation element from a U-shaped bent Metal tube of defined wall thickness and strength. As materials come the requirements Accordingly, both steel and light metals are considered. Possibly can but also uses other open profiles for the deformation element be.
Ferner kann das Deformationselement mit seinem Basisteil hinter einem geschlossenen Außenhaut-Querelement der Bugschürze angeordnet sein, an das oberhalb und unterhalb des Querelementes durch Luftschlitze unterbrochene Abschnitte anschließen. Das geschlossene Querelement verdeckt das oberhalb des Stoßfängers positionierte, zweite Deformationselement und dient zugleich als Kraft verteilende Stützfläche bei entsprechenden Kollisionen.Further the deformation element with its base part behind a closed Skin cross member the front apron be arranged on the above and below the cross member through Louvers connect interrupted sections. The closed cross element obscured that positioned above the bumper, second deformation element and also serves as a force distributing Support surface at corresponding collisions.
Schließlich kann in weiterer vorteilhafter Ausgestaltung der Erfindung die Bugschürze funktionell mit dem zweiten Deformationselement zusammenwirken, indem dessen Außenhaut-Querelement im Querschnitt gesehen etwa L-förmig mit einem im Wesentlichen senkrechten Abschnitt und einem horizontal nach hinten gerichteten Abschnitt gestaltet ist, wobei das Basisteil des Deformationselementes unterhalb des horizontalen Abschnittes an dem vertikalen Abschnitt positioniert ist. Daraus resultiert bei einer crashbedingten Verformung der Bugschürze nach hinten, dass diese sich formschlüssig mit dem Basisteil des Deformationselementes verhakt und somit eine zunehmende Energieabsorption ermöglicht.Finally, in a further advantageous embodiment of the invention, the front apron functionally interact with the second deformation element by the outer skin cross member is seen in cross-section approximately L-shaped with a substantially vertical portion and a horizontally rearwardly directed portion, wherein the base part of the deformation element is positioned below the horizontal portion at the vertical portion. This results in a crash-induced deformation of the front apron that the rear hooks form-fitting with the base part of the deformation element and thus allows an increased energy absorption.
