Abstract

Der beschriebene Schaftstab (4) geht von einem Aluminiumstrangpressprofil mit relativ dicken Seitenwänden aus, die bereichsweise abgetragen und dadurch dünner gemacht werden. Dies kann ohne wesentliche Beeinträchtigung der Steifigkeit des Schaftstabs geschehen, wodurch aber eine wesentliche Gewichtsersparnis erzielt wird. Der Materialabtrag kann den lokalen Belastungsverhältnissen angepasst werden. Beispielsweise ist es möglich, an den Enden oder sonstigen Krafteinleitungsstellen ungeschwächte dicke Wände zu belassen während die übrigen Bereiche der Seitenwände so weit abgefräst werden, dass eine einheitliche dünnere Wandstärke erreicht wird. Es ist darüber hinaus möglich, das Maß des Materialabtrags in mehreren Stufen oder stufenlos zu variieren. Der Materialabtrag betrifft eine Verminderung der Wandstärke, die quer zur Bewegungsrichtung des Schaftstabs gemessen wird. Zusätzlich kann die Profilhöhe des Schaftstabs z.B. durch geeignetes Abfräsen des Vollprofilbereichs zu den Enden hin variiert werden, wobei diese in Bewegungsrichtung H gemessen wird.

Figure 00000001
The shaft rod (4) described is based on an aluminum extruded profile with relatively thick side walls, which are partially removed and thereby made thinner. This can be done without significantly affecting the stiffness of the shaft rod, but a significant weight saving is achieved. The material removal can be adapted to the local load conditions. For example, it is possible to leave unattenuated thick walls at the ends or other force introduction points while the remaining areas of the side walls are milled off so far that a uniform thinner wall thickness is achieved. It is also possible to vary the degree of material removal in several stages or continuously. The material removal relates to a reduction in the wall thickness, which is measured transversely to the direction of movement of the shaft rod. In addition, the profile height of the shaft rod can be varied, for example, by suitable milling of the solid profile area towards the ends, wherein this is measured in the direction of movement H.
