Abstract
Description
Die Erfindung beschreibt eine Crashbox mit einer Frontseite, die vom Fahrzeug weg zeigt, einer Heckseite, die an einem Längsträger festlegbar ist, und vier Längsseiten, die die Front- und die Heckseite verbinden.The The invention relates to a crash box with a front end, which is from Vehicle away shows a rear side, which can be fixed to a side member is, and four long sides, which connect the front and the rear side.
Stoßfängersysteme werden heute standardmäßig bei Kraftfahrzeugen vorne und hinten eingebaut, um die Stoßenergie kleinerer Stöße so abzufangen, dass die eigentliche Tragstruktur des Autos möglichst nicht beschädigt wird. Dabei besteht ein Stoßfängersystem in der Regel aus einem Stoßenergie in Verformungsarbeit umwandelnden Bauteil wie der Crashbox und einem Querträger, der dazu dient, die aus einem Anprall resultierende Energie in die Crashbox einzuleiten. Ferner leistet der Querträger selbst auch einen Teil der Verformungsarbeit. Das Stoßfängersystem wird dabei so aufeinander abgestimmt, dass die Crashbox möglichst mittig auf dem Längsträger des Autos sitzt und die Stoßenergie über den Querträger mit einem möglichst geringen Biegemoment in die Crashbox und den Längsträger eingeleitet wird.bumper systems are standard today Vehicles front and rear mounted to the impact energy intercept smaller impacts so that the actual supporting structure of the car is not damaged as much as possible. There is a bumper system usually from a shock energy in deformation work transforming component such as the crashbox and a Crossbeam, which serves the energy resulting from an impact in the crash box initiate. Furthermore, the cross member itself also makes a part the deformation work. The bumper system is coordinated so that the crash box as possible centered on the side member of the Cars sits and the impact energy over the crossbeam with one as possible low bending moment is introduced into the crash box and the longitudinal member.

der
Aufgabe der Erfindung ist es, ein Stoßfängersystem bereitzustellen, dass hinsichtlich Crashverhalten, Designfreiheit und Gewicht weiter optimiert ist.task The invention is a bumper system provide that in terms of crash behavior, design freedom and weight is further optimized.
Diese Aufgabe löst die Erfindung mit einer Crashbox gemäß Anspruch 1. Demnach besteht die Crashbox auf drei Längsseiten aus einem U-förmigen Blech. Die vierte Längsseite wird von einem L-förmigen Schließblech gebildet. Das U-förmige und das L-förmige Blech sind fest miteinander verbunden. Die vom Fahrzeug wegzeigende Frontseite der Crashbox ist durch die abgewinkelte Seite des L-förmigen Schließblechs verschlossen. Durch das geschlossene Profil ist die Crashbox verwindungssteif. Das abgewinkelte, insgesamt L-förmige Schließblech kann über eine Schweißnaht sowohl an der Längsseite als auch an der Frontseite mit dem U-Profil verbunden werden. An ihrer Heckseite sitzt die Crashbox entweder direkt auf dem Längsträger oder auf einer herkömmlichen Flanschplatte auf, mit der die Crashbox am Längsträger befestigt werden kann. In oder an das Schließblech an der Frontseite der Crashbox kann eine Abschleppeinheit angebracht werden, die in der Lage ist, die Kräfte zu übertragen, die beim Abschleppen auftreten. Die Crashbox besitzt bevorzugt wie herkömmliche Crashboxen aus dem Stand der Technik auch einen in etwa rechteckigen Querschnitt und läuft in Längsrichtung konisch zu. Die Crashbox kann mit Sicken oder Löchern zur gezielten Faltenbildung versehen sein. Erfindungsgemäß ist die Crashbox an der Frontseite jedoch immer durch das abgewinkelte L- Blech geschlossen.These Task solves the invention with a crash box according to claim 1. Accordingly the crashbox on three long sides from a U-shaped Sheet. The fourth long side is from an L-shaped striking plate educated. The U-shaped and the L-shaped one Sheet metal are firmly connected. The pointing away from the vehicle The front of the crash box is through the angled side of the L-shaped strike plate locked. Due to the closed profile, the crash box is torsionally rigid. The Angled, generally L-shaped Striker can over a Weld both on the long side as well as be connected to the U-profile at the front. At the rear of the crash box sits either directly on the side rail or on a conventional Flange plate with which the crash box can be attached to the side member. In or on the strike plate a towing unit can be attached to the front of the crash box who is capable of the forces to transfer that when towing occur. The crash box preferably has like conventional Crashboxes from the prior art also has an approximately rectangular Cross section and running longitudinal conical too. The Crashbox can be used with beads or holes for targeted wrinkling be provided. According to the invention Crashbox at the front but always by the angled L- Sheet closed.
Die erfindungsgemäße Crashbox ist in der Lage, die gesamte vom Lastenheft geforderte Stoßenergie im Crashfall in Verformungsenergie umzuwandeln und die Abschleppkräfte im Abschleppfall aufzunehmen. Folglich ist ein Querträger, der die auf je einem Längsträger festgelegten Crashboxen miteinander verbindet, überflüssig oder zumindest muss der Querträger keine Stoßenergie umwandeln oder Abschleppkräfte aufnehmen können. Somit kann der Querträger entsprechend leicht gebaut werden oder sogar ganz entfallen. Dadurch kann erhebliches Gewicht eingespart werden. Ein Fußgängerschutz kann nach wie vor über Schaumblöcke oder ähnliches realisiert werden. Der fehlende oder geschwächte Querträger hebt den Zug- und Druckverbund des erfindungsgemäßen Stoßfängersystems weitgehend auf. Ein keilförmiger Gegenstand, auf den das Fahrzeug bei einem Frontalaufprall trifft, kann allerdings leichter in den Motorraum eindringen als bei einem herkömmlichen System. Bevorzugt wird das erfindungsgemäße Stoßfängersystem daher bei einem heckseitigen Stoßfänger eines Fahrzeugs eingesetzt.The crash box according to the invention is capable of all the impact energy required by the specifications to convert into deformation energy in the event of a crash and the towing forces in towing take. Consequently, a cross member, which defined on each one longitudinal beam Crash boxes together, superfluous or at least the cross member no impact energy convert or towing be able to record. Thus, the cross member be built accordingly easy or even completely eliminated. Thereby considerable weight can be saved. A pedestrian protection can still over foam blocks or similar will be realized. The missing or weakened cross member raises the tension and compression bond the bumper system according to the invention largely on. A wedge-shaped Object hit by the vehicle in a frontal impact, However, it can penetrate the engine compartment more easily than one usual System. The bumper system according to the invention is therefore preferably in a rear bumper one Vehicle used.
