Description

Die Erfindung betrifft eine Federunterlage für Blattfedern, insbescndere von Fahrzeugen, die an ihrem Außenrand von der Blattfeder weggebogen und ao zur Anordnung zwischen der Blattfeder und dem Federsattel bestimmt ist.The invention relates to a spring pad for leaf springs, in particular of vehicles, which are attached to their Outer edge bent away from the leaf spring and ao for the arrangement between the leaf spring and the Spring saddle is intended.

Eine derartige, als starre Platte ausgebildete Unterlage ist der USA.-Patentschrift 3 097 840 zu entnehmen, wobei die Größe und Form der Abbiegung für eine straffe Abfederung ausreichend erscheint. Bei einer weichen Federung ist beim Einfedern jedoch damit zu rechnen, daß die Blattfeder auf der scharfen Kante de.· Abbiegung zur Anlage gelangt, wodurch eine hohe Spannungsspitze auftritt, die unter Umständen zu einem Federbruch- führen kann.Such a base, designed as a rigid plate, can be found in US Pat. No. 3,097,840, the size and shape of the bend appear to be sufficient for a firm cushioning. In the case of a soft suspension, however, it is to be expected that the leaf spring on the sharp edge de Can lead to a spring break.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, unter Umgehung der Nachteile der bekannten Ausführung eine Federunterlage zu schaffen, die auch bei extrem großen Federwegen die Bildung unzulässiger Spannuagsspitzen ausschließt.The present invention was therefore based on the object of avoiding the disadvantages of the known ones Execution to create a spring pad that supports the formation even with extremely large spring deflections excludes impermissible voltage peaks.

Es wird deshalb zur Lösung dieser Aufgabe eine Federunterlage für Blattfedern, insbesondere von Fahrzeugen, die an ihrem Außenrand von der Blattfeder weggebogen und zur Anordnung zwischen der Blattfeder und dem Federsattel bestimmt ist, vorgeschlagen, wobei erfindungsgemäß die Federunteriage in an sich bekannter Weise aus Flachstahl besteht, ihre Enden eingerollt sind und sich bei Belastung federnd am Federsattel abstützen.It is therefore to solve this problem a spring pad for leaf springs, in particular from Vehicles that are bent away from the leaf spring at their outer edge and placed between the Leaf spring and the spring saddle is intended, proposed, according to the invention, the spring underlay consists of flat steel in a manner known per se, its ends are rolled up and are resilient when loaded support on the spring saddle.

Dadurch wird außerdem erreicht, dali sich der Übergangsradius bei Belastung vergrößert und die Abstützkraft so besonders günstig in die Blattfeder eingeleitet wird.This also ensures that the Transition radius increased under load and the Support force is introduced into the leaf spring so particularly favorably.

Der Gegenstand der Erfindung soll im folgenden an Hand eines in der Zeichnung in einer Seitenansicht dargestellten Ausführungsbeispiels näher erläutert werden.The subject matter of the invention is intended below with reference to one in the drawing in a side view illustrated embodiment are explained in more detail.

Die aus mehreren Federblättern 1 bestellende Blattfeder 2 ist unter Zwischenschaltung einer Federunterlage 3 auf dem Federsattel 4, der mit dem Achsrohr 5 verschweißt ist, gelagert. Die beiden Enden der Federunterlage 3 sind so eingerollt, daß die eingerollten Teile von der Blattfeder 2 weg gerichtet sind und sich — im belasteten Zustand — an dem Federsattel 4 abstützen. In nicht dargestellter Weise kann die Federunterlage 3 eine Bohrung zur Durchführung eines Herzbolzens aufweisen oder aber auch mit seitlichen Ausnehmungen zur Führung der Lasche der Blattfeder 2 versehen sein. Bei einer Achsbrücke mit verschiedenen Federspuren kann die Federunterlage dann einfach z. B. auf die jeweils erforderliche Herzbolzenbohrung aufgelegt werden.The leaf spring 2 ordered from several spring leaves 1 is with the interposition of a spring pad 3 on the spring saddle 4, which is welded to the axle tube 5, mounted. The two ends of the spring pad 3 are rolled up in such a way that the rolled-up parts are directed away from the leaf spring 2 and - in the loaded state - are supported on the spring saddle 4. In a manner not shown The spring pad 3 can have a hole for the implementation of a heart bolt or else be provided with lateral recesses for guiding the tab of the leaf spring 2. With an axle bridge with different feather marks, the feather pad can then simply z. B. to the required Heart bolt hole are placed.
