Abstract
Description
Die Erfindung bezieht sich auf einen stoßabsorbierenden Karosserieträger, insbesondere einen Karosserielängsträger für einen Vorderwagen oder einen Hinterwagen einer Karosserie für einen Personenkraftwagen nach dem Oberbegriff des Anspruchs 1.The Invention relates to a shock absorbing body support, in particular a body side member for one Front end or rear end of a body for one Passenger car according to the preamble of claim 1.
Aus
der
Die GB 2 308 100 behandelt einen Stoßfänger für eine Karosserie eines Personenkraftwagens, welcher erste und zweite, hintereinandergeschaltete Deformationsglieder aufweist, wobei die ersten Deformationsglieder bereits bei einer relativ geringen Stoßbelastung deformierbar und innerhalb des eigentlichen Stoßfängerprofils angeordnet sind, während die zweiten Deformationsmittel erst bei einer erheblich höheren Stoßbelastung Energie aufnehmen und im Bereich zwischen dem Stoßfänger und einem vorderen bzw. hinteren Karosseriequerträger angeordnet sind. Solcherart ausgebildete Einrichtungen zur Absorption von aus einer Havarie des Fahrzeuges resultierender Stoßbelastungen sind für einen wirksamen Abbau höherer Stoßbelastungen weniger gut geeignet, da sie nur über geringe Deformationswege verfügen und daher für die Aufnahme von Stoßenergie nur begrenzt geeignet sind.The GB 2 308 100 deals with a bumper for a body of a passenger car, which first and second deformation elements connected in series has, the first deformation members already at one relatively low impact load deformable and arranged within the actual bumper profile, while the second deformation means only with a significantly higher shock load Absorb energy and in the area between the bumper and a front or rear body cross member are arranged. of such trained facilities for absorption from an accident resulting shock loads of the vehicle are effective for Reduction of higher shock loads less suitable because they only have small deformation paths feature and therefore for the absorption of impact energy are only suitable to a limited extent.
Der Erfindung liegt ausgehend von dem vorstehend aufgezeigten Stand der Technik die Aufgabe zugrunde einen stoßabsorbierenden Karosserieträger, insbesondere einen Karosserielängsträger für einen Vorderwagen oder einen Hinterwagen einer Karosserie für einen Personenkraftwagen zu schaffen, welcher mit einem geringen technischen und wirtschaftlichen Aufwand herstellbar ist und über einen relativ langen Verformungsweg die Aufnahme entweder gleichförmiger oder stufenweise zunehmender Deformationskräfte ermöglicht.The Invention lies on the basis of the state shown above the technology the task of a shock-absorbing body support, in particular a body side member for one Front end or rear end of a body for one To create passenger cars, which with a low technical and economic effort is producible and relative long deformation path either uniform or inclusion gradually increasing deformation forces.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungsformen sind in den Unteransprüchen angegeben.This The object is achieved by the Features specified in claim 1 solved. Advantageous further training and practical designs are in the subclaims specified.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen in einem relativ langen, zur Verfügung stehenden Verformungsweg und damit in der Möglichkeit in einem Crashfall auch sehr hohe Stoßkräfte in Verformungsarbeit umzuwandeln. Die Verwendung einer Vielzahl durch Längenabschnitte eines dünnwandigen Rohrmaterials kleinen Durchmessers gebildeter und zu einem Verbund zusammengefasster rohrförmiger Elemente als Deformationselemente bringt dabei zudem den Vorteil eines geringen technischen Aufwandes bei der Herstellung der Deformationselemente und zugleich auch für deren Einbau in einen Karosserielängsträger mit sich. Insbesondere ermöglicht die Zusammenfassung einer Anzahl solcher dünnwandigen Rohrmaterialabschnitte zu einem Verbund bzw. zu einem Einsatzteil die Unterbringung der Deformationselemente insgesamt innerhalb eines üblichen, entweder aus zwei Blechhalbschalen oder aus einem Strangpressprofil gebildeten viereckigen oder achteckigen Längsträgerhohlprofils, dergestalt, dass für die stoßabsorbierende Ausbildung eines Karosserielängsträgers kein zusätzlicher Bedarf an Einbauraum entsteht.The with the invention mainly Advantages achieved are a relatively long, available Deformation path and thus possible in the event of a crash also very high impact forces in deformation work convert. The use of a variety of lengths one thin-walled Pipe material of small diameter and formed into a composite summarized tubular Elements as deformation elements also have the advantage a low technical effort in the production of the deformation elements and at the same time for their installation in a body side member with itself. In particular allows the summary of a number of such thin-walled pipe material sections the composite elements or an insert part, the accommodation of the deformation elements overall within a normal, either from two sheet metal half shells or from an extruded profile formed square or octagonal side member hollow profile, such that that for the shock absorbing Training of a body side member no additional There is a need for installation space.
In einer vorteilhaften Weiterbildung kann hierbei ferner vorgesehen sein, dass zur Erzielung einer mit zunehmendem Verformungsweg abgestuft zunehmenden Verformungsarbeit die zu einem Einsatzteil verbundenen Rohrmaterialabschnitte unterschiedliche Längen aufweisen, und bevorzugter Weise derart angeordnet sind, dass die längengleich zum Karosserielängsträger bemessenen Längenabschnitte eines dünnwandigen Rohrmaterials bezüglich der Karosserielängsträger Längsmittelachse in vertikalen Ebenen übereinander und in horizontaler paarweise einander gegenüberliegend angeordnet sind und die um einen ersten Betrag kürzer als der Karosserielängsträger bemessenen Längenabschnitte eines dünnwandigen Rohrmaterials in einer vertikalen Längsmittelebene des Karosserielängsträgers übereinanderliegend und ferner die um einen zweiten Betrag kürzer als der Karosserielängsträger bemessenen Längenabschnitte eines dünnwandigen Rohrmaterials in horizontalen Ebenen paarweise nebeneinanderliegend und in vertikaler Ebene einander gegenüberliegend angeordnet sind.In An advantageous further development can also be provided be that in order to achieve a gradual increase with increasing deformation path Deformation work the pipe material sections connected to an insert different lengths have, and are preferably arranged such that the coextensive dimensioned to the body side member lengths one thin-walled Pipe material regarding the body longitudinal member longitudinal central axis one above the other in vertical planes and are arranged horizontally in pairs opposite to each other and shorter by a first amount than the body side member dimensioned lengths one thin-walled Pipe material lying one above the other in a vertical longitudinal median plane of the body side member and also those dimensioned a second amount shorter than the body side member lengths a thin-walled pipe material in pairs on horizontal levels and vertically Level opposite each other are arranged.
In einer weiteren vorteilhaften Ausgestaltungsform kann ferner vorgesehen sein, dass zur Erzielung einer stufenweise zunehmenden Verformungsarbeit Rohrmaterialabschnitte unterschiedlicher Länge und zugleich unterschiedlichen Durchmessers eingesetzt werden.In a further advantageous embodiment, it can further be provided that, in order to achieve a stepwise increasing deformation work, tube material sections of different lengths and at the same time different diameters knife can be used.
