Description

Blattfeder. Es sind bereits Blattfedern bekannt, bei _ welchen zwischen den einzelnen Blättern Zwischenlagen aus Metall vorgesehen sind, die bezwecken sollen, die Reibung der Federblätter unter sich zu verringern oder eine Feder mit rasch wachsender Tragkraft herzustellen. Bei diesen bekannten Anordnungen sind aber die Zwischenlagen mit den einzelnen Federblättern nicht metallisch verbunden, so daß die Feder nicht vor dem Rosten geschützt ist. Ferner ist es bereits bekannt, bei derartigen Anordnungen einzelne Federblätter auf einer Seite mit Messing zu plattieren, während die andere Seite frei bleibt. Diese Anordnung bedeutet zwar gegenüber der vorhergehenden eine Verbesserung; aber auch bei dieser wird das Rosten der Feder nicht verhindert, weil die eine Seite nicht mit einem metallischen Überzug versehen ist.Leaf spring. Leaf springs are already known in which between the individual sheets are provided with intermediate layers of metal, which are intended to reduce the friction between the spring leaves or use a spring quickly increasing load capacity. In these known arrangements, however, are the Intermediate layers with the individual spring leaves are not connected to metal, so that the spring is not protected from rusting. Furthermore, it is already known at such arrangements to clad individual spring leaves on one side with brass, while the other side remains free. Although this arrangement means opposite the previous one improvement; but even with this the spring will rust not prevented because one side is not provided with a metallic coating is.

Gegenstand vorliegender Erfindung ist eine weitere Verbesserung dieser bekannten Anordnung, und zwar besteht die Erfindung darin, daß jedes einzelne Blatt vollständig mit einer Metallschicht überzogen ist. Zweckmäßig wird dabei ein weiches, schmierendes Metall, z. B. Zinn, Zink, Blei, oder eine von deren Legierungen verwendet, so daß also die Feder gleichzeitig geschmiert wird und gegen Rosten geschützt ist. Die Herstellung des Metallüberzuges kann dabei am besten nach dem bekannten Metallspritzverfahren erfolgen, weil es dadurch möglich ist, den Überzug aufzubringen, ohne daß die Feder dem Einfluß von Säuren oder übermäßiger Erwärmung ausgesetzt wird, wie dies durch die bekannten Verfahren (Tauchverfahren, galvanisches Verfahren) bedingt ist.The subject of the present invention is a further improvement of these known arrangement, namely the invention consists in that each individual sheet is completely covered with a metal layer. A soft, lubricating metal, e.g. B. tin, zinc, lead, or one of their alloys is used, so that the spring is lubricated and protected against rusting at the same time. The production of the metal coating can best be done using the known metal spraying process because it is possible to apply the coating without the spring exposed to the influence of acids or excessive heating, as caused by the known processes (immersion process, galvanic process).
