Abstract
Description
Die Erfindung bezieht sich auf eine A-Säule für eine Karosserie eines Kraftfahrzeuges mit einem Innenblech und einem Außenblech nach dem Oberbegriff des Anspruchs 1.The invention relates to an A-pillar for a body of a motor vehicle with an inner panel and an outer panel according to the preamble of
Aus der
Aufgabe der Erfindung ist es, eine A-Säule für eine Karosserie eines Kraftfahrzeugs zu schaffen, die einen möglichst schlanken Querschnitt mit geringen Sichtverdeckungswinkel aufweist und die gegen ein lokales Einknicken unter Krafteinwirkung, vorzugsweise bei einem Dachfalltest, entsprechend verstärkt ausgeführt ist.The object of the invention is to provide an A-pillar for a body of a motor vehicle, which has a slender cross section as possible with low viewing angle and which is carried out correspondingly strengthened against a local buckling under the action of force, preferably in a roof drop test.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the features of
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass durch die Einbringung von Verstärkungselementen in die A-Säule des Kraftfahrzeugs ein relativ schlanker Querschnitt der A-Säule geschaffen werden kann, da die Verstärkungselemente an der schwächsten Stelle der A-Säule positioniert sind und somit die Festigkeit in diesem Bereich mittels der Verstärkungselemente optimal erhöht wird. Dies wird nach der Erfindung erreicht, indem die Verstärkungselemente aus einem Schottblech oder mehreren Schottblechen einem sog. Schottblechelement bestehen, wobei das Schottblech oder die Schottbleche zwischen dem Innen- und Außenblech der A-Säule in einer Querebene angeordnet und rundherum anliegend innerhalb der A-Säule mit dem Innen- und Außenblech verbunden sind.The advantages achieved by the invention are that a relatively slender cross section of the A-pillar can be created by the introduction of reinforcing elements in the A-pillar of the motor vehicle, since the reinforcing elements are positioned at the weakest point of the A-pillar and thus the strength is optimally increased in this area by means of the reinforcing elements. This is achieved according to the invention by the reinforcing elements consist of a bulkhead or more bulkhead plates a so-called. Schott sheet metal element, wherein the bulkhead or the bulkhead plates between the inner and outer plates of the A-pillar arranged in a transverse plane and lying all around within the A-pillar are connected to the inner and outer panels.
Insbesondere ist das Schottblech aus einem Formteil mit von einer ebenen Platte abgestellten Flanschen bestehend, die entgegengesetzt ausgerichtet und den profilierten Formverlauf des Innen- und Außenbleches folgend ausgeführt sind. Der dem Innenblech zugerichtete eine Flansch ist durch Schweißpunkte innenseitig mit dem Innenblech verbunden und der dem Außenblech zugerichtete weitere Flansch ist innenseitig mit dem Außenblech durch eine Klebung verbunden. Durch diese Anordnung und Ausbildung des Verstärkungselements in der A-Säule zwischen dem Innen- und Außenblech wird ein lokales Knicken und Beugen, vorzugsweise des Innenbleches der A-Säule verhindert bzw. minimiert.In particular, the partition plate is made of a molded part with parked from a flat plate flanges, which are oppositely aligned and executed following the profiled shape of the inner and outer sheets. The one of the inner panel zugereichtete a flange is connected by welding points on the inside with the inner panel and the outer panel zugerichtete further flange is connected on the inside to the outer panel by gluing. This arrangement and design of the reinforcing element in the A-pillar between the inner and outer metal sheet local bending and bending, preferably of the inner panel of the A-pillar is prevented or minimized.
Das Verstärkungselement kann somit bei einer Krafteinleitung, vorzugsweise bei einem sogenannten Dachfalltest, am oberen Ende der Säule ein Knicken/Beulen des Querschnitts der A-Säule unterbinden, wobei zudem durch entsprechende Blechdicken und Werkstoffauswahl des Schottbleches die Stärke des Knicks der A-Säule beeinflussbar ist.The reinforcing element can thus prevent kinking / buckling of the cross section of the A-pillar at a force introduction, preferably in a so-called rooffall test at the top of the column, which also by appropriate thicknesses and material selection of the bulkhead plate, the strength of the buckling of the A-pillar can be influenced ,
Nach einer weiteren Ausführung der Erfindung kann das Verstärkungselement auch aus zwei miteinander verbundenen Schottblechen, einem sogenannten Schottblechelement bestehen. Diese beiden Schottbleche sind in Längsrichtung der A-Säule hintereinander angeordnet und über einen Längssteg miteinander verbunden und stehen in einem Abstand zueinander.According to a further embodiment of the invention, the reinforcing element may also consist of two interconnected bulkhead plates, a so-called bulkhead plate element. These two bulkhead plates are arranged one behind the other in the longitudinal direction of the A-pillar and connected to one another via a longitudinal web and are at a distance from one another.
Der Längssteg ist an mindestens einer Außenseite der einzelnen Schottbleche des Schottblechelements angeordnet, wobei zwei Flansche miteinander verbunden sind, welche dem Innen- oder Außenblech der A-Säule zugerichtet sind. Durch diese Ausführung wird insbesondere das Innenblech der A-Säule auf einer längeren Basis festigkeitsmäßig mehr unterstützt, als mit nur einem Schottblech, so dass ein lokales Knicken und Beulen des Innenbleches der A-Säule unter Krafteinleitung wirksam verhindert wird.The longitudinal web is arranged on at least one outer side of the individual bulkhead plates of the bulkhead sheet metal element, wherein two flanges are connected to each other, which are trimmed to the inner or outer sheet of the A-pillar. By this embodiment, in particular the inner panel of the A-pillar on a longer basis strength more supportive than with only one bulkhead plate, so that a local buckling and buckling of the inner panel of the A-pillar is effectively prevented by force.
Nach einer weiteren Ausführung der Erfindung besteht das Verstärkungselement aus einem im Querschnitt u-förmigen Blechteil, das einen flächig an einer Innenwandung des Innenbleches der A-Säule anliegenden profilierten Steg aufweist, der in einer Querebene der A-Säule ausgeprägte und mit Abstand zueinander liegende tunnelartige Erhöhungen nach Art eines Wellbleches aufweist. Dieses Blechteil weist zwischen den tunnelartigen Erhöhungen jeweils mit der Innenwandung des Innenbleches der A-Säule flächig aufliegende Abschnitte auf, die mit der Innenwandung des Innenbleches durch Schweißpunkte verbunden sind. Ebenfalls sind vom Steg abgestellte Schenkel des Blechteils mit der Innenwandung des Innenbleches durch Schweißpunkte verbunden. Mit diesem profilierten u-förmigen Blechteil, das auch an der schwächsten Stelle der A-Säule, bzw. des Innenbleches angeordnet ist, wird eine Verdopplung der Wandstärke des Innenbleches in einem längeren Bereich des Profilquerschnitts der A-Säule erzielt, so dass ein Knicken und Beulen des Innenbleches in einen unkritischen Bereich außerhalb des profilierten Blechteils verlagert werden kann.According to a further embodiment of the invention, the reinforcing element consists of a cross-sectionally U-shaped sheet metal part which has a flat applied to an inner wall of the inner panel of the A-pillar profiled web, in a transverse plane of the A-pillar pronounced and spaced apart tunnel-like Has elevations in the manner of a corrugated sheet. This sheet metal part has between the tunnel-like elevations in each case with the inner wall of the inner panel of the A-pillar surface resting portions which are connected to the inner wall of the inner panel by welds. Also parked from the web leg of the sheet metal part with the inner wall of the inner panel are connected by welds. With this profiled U-shaped sheet metal part, which is also located at the weakest point of the A-pillar, or the inner panel, a doubling of the wall thickness of the inner panel is achieved in a longer region of the profile cross-section of the A-pillar, so that a buckling and Bumps of the inner panel can be moved in a non-critical area outside of the profiled sheet metal part.
