Abstract
Description
Die Erfindung betrifft ein energieabsorbierendes Deformationsele ment zum Schutz der Kraftzeugkarosserie und zum Einbau zwischen einem Stoßfänger und einem Längsträger.The invention relates to an energy-absorbing deformation element ment to protect the vehicle body and for installation between one Bumper and a side member.
Bei einem Auffahrunfall mit geringer Geschwindigkeit zwischen 10 und 20 km/h kommt es bereits zu Deformationen der Karosserie, insbe sondere der Längsträger. Auch die Stoßfänger können dies nicht verhin dern.In a rear-end collision at low speed between 10 and 20 km / h there are already deformations of the body, in particular especially the side member. The bumpers cannot prevent this either other.
Bekannt sind teleskopartige Systeme, die jedoch sehr aufwendig sind. Bei nicht axialer Krafteinleitung versagen diese Systeme z. B. infolge Abknickens der Kolbenstangen.Telescopic systems are known, but they are very complex are. With non-axial force transmission, these systems fail e.g. B. due to kinking of the piston rods.
Aufgabe der Erfindung ist die Bereitstellung eines Deformationse lements, das bei einfachem Aufbau eine hohe Energieabsorption aufweist und das schnell montierbar und austauschbar ist.The object of the invention is to provide a deformation elements that have a high energy absorption with a simple structure and that can be quickly assembled and exchanged.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß ein Gehäuse mit Aluminiumschaum als Energieabsorber gefüllt ist.This object is achieved according to the invention in that a Housing is filled with aluminum foam as an energy absorber.
Die Erfindung unterscheidet sich insofern vom Stand der Technik, als das mit Aluminiumschaum gefüllte Gehäuse leicht und schnell mon tierbar sowie nach einer Deformation austauschbar ist. Die große Ener gieabsorption verhindert innerhalb eines weiten Bereich eine Deforma tion oder sonstige Beschädigung der Längsträger. Nach Untersuchungs ergebnissen hat Aluminiumschaum eine besonders hohe spezifische Ener gieaufnahmekapazität. Die Werkstoffkombination Aluminium/Aluminiumschaum bzw. Kunststoff/Aluminiumschaum erzielt man ein geringes Gewicht, wodurch die Gewichtsreduzierung im Fahrzeugbau gefördert wird. The invention differs from the prior art in that than the housing filled with aluminum foam easily and quickly mon animal and interchangeable after deformation. The great ener Gi absorption prevents deformity within a wide range tion or other damage to the side members. After investigation results, aluminum foam has a particularly high specific energy casting capacity. The combination of materials Aluminum / aluminum foam or plastic / aluminum foam is achieved a low weight, which reduces weight in vehicle construction is promoted.
Eine kostengünstige Ausbildung erzielt man dadurch, daß das Ge häuse als Kunststoffspritzgußteil ausgebildet ist. Das Kunststoff spritzgußgehäuse kann weitere Funktionen, wie Clipsbefestigung, Ab dichtung und Kabelführungen übernehmen.Inexpensive training is achieved in that the Ge housing is designed as a plastic injection molded part. The plastic Injection molded housing can have other functions, such as clip attachment, Ab Take over seal and cable routing.
Die Recyclingfähigkeit wird dadurch verbessert, daß das Gehäuse als Aluminiumstrangpreßteil oder als Aluminiumblechformteil ausgebil det ist.The recyclability is improved in that the housing trained as an aluminum extrusion or as an aluminum sheet molded part det.
Leichte Stöße bei Fahrzeuggeschwindigkeiten bis zu 5 km/h können dadurch absorbiert werden, daß das Gehäuse aus einem elastischen rück stellfähigen Kunststoff besteht. Die Rückstellfähigkeit läßt das De formationselement unversehrt, so daß bei geringen Aufprallgeschwindig keiten ein Austausch des Deformationselements nicht erforderlich ist.Slight bumps at vehicle speeds of up to 5 km / h can are absorbed in that the housing from an elastic back adjustable plastic is made. The resilience leaves the De formation element intact, so that at low impact speed an exchange of the deformation element is not necessary.
Eine weitere Anpassungsmöglichkeit ist dadurch möglich, daß das Gehäuse mehrere Kammern aufweist.Another possibility of adaptation is possible in that the Housing has several chambers.
Eine Steuerung der Verformung ist dadurch möglich, daß die Konfi guration des Gehäuses der gewünschten Verformung angepaßt ist.Control of the deformation is possible in that the confi guration of the housing is adapted to the desired deformation.
Eine besonders feinfühlige Anpassung wird dadurch erzielt, daß die Wanddicke des Gehäuses variierend oder daß das Gehäuses als Fal tenbalg ausgebildet ist. Das Verformungsverhalten läßt sich in positi ver Weise beeinflussen. Der Verformungsweg läßt sich vergrößern.A particularly sensitive adjustment is achieved in that the wall thickness of the housing varies or that the housing as a case tenbalg is formed. The deformation behavior can be positi influence wise. The deformation path can be increased.
Ein Hauptvorteil des beschriebenen Deformationselements ist die Fähigkeit, auch in nicht axialer Richtung eingeleitete Energie zu ab sorbieren. Die Energiabsorption ist im Vergleich zum Bauteilgewicht sehr groß.A major advantage of the described deformation element is that Ability to absorb energy introduced in a non-axial direction sorb. The energy absorption is compared to the component weight very large.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert, die in schematischer Darstellung ein Kraftfahrzeug mit einem Deformationselement zeigt.An embodiment of the invention is based on the drawing explains the schematic representation of a motor vehicle shows a deformation element.
Die Zeichnung zeigt in schematischer Teilansicht ein Kraftfahr zeug 1 mit einem Längsträger 2 und einem Stoßfänger 3. Einzelheiten der Konstruktion des Längsträgers 2 und des Stoßfängers 3 sind nicht dargestellt.The drawing shows a schematic partial view of a motor vehicle 1 with a side member 2 and a bumper 3rd Details of the construction of the longitudinal beam 2 and the bumper 3 are not shown.
Zwischen dem Stoßfänger 3 und dem Längsträger 2 ist das Deforma tionselement 4 befestigt. Das Deformationselement 4 umfaßt ein Gehäuse 5 mit einer oder mehreren Kammern 7. Das Gehäuse 5 bzw. die Kammern 7 nehmen je eine Füllung 6 aus Aluminiumschaum auf.Between the bumper 3 and the side member 2 , the deformation element 4 is attached. The deformation element 4 comprises a housing 5 with one or more chambers 7 . The housing 5 and the chambers 7 each hold a filling 6 made of aluminum foam.
Ein Rückstellabschnitt 8 des Gehäuses 5 bestseht aus einem ela stischen rückstellfähigen Kunststoff. Dieser Rückstellabschnitt 8 kann leichte Stöße elastisch aufnehmen, ohne daß eine Verformung erfolgt.A reset section 8 of the housing 5 consists of an elastic resilient plastic. This reset section 8 can absorb light impacts elastically without deformation.
