Description

Die Erfindung bezieht sich auf eine Abfederung, insbesondere für Kraftfahrzeuge, mit einem um zwei gegeneinander beweglichen Gummirollen gelegten elastischen Zugband'.The invention relates to a cushioning, especially for motor vehicles, with one movable by two against each other Rolled elastic drawstring 'with rubber rollers.

Bei der Anwendung solcher Federungen an Kraftfahrzeugen werden ,an die Dauerbruchsicherheit der elastischen Zugbänder besonders große Anforderungen gestellt.When using such suspensions on motor vehicles, the fatigue resistance the elastic drawstrings placed particularly high demands.

" Es ist bekannt, die Auflagerollen für die Gummibänder aus harten Werkstoffen, wie Metall oder Kunstharz, herzustellen oder auch aus Gummi und Gewebe zusammenzusetzen. Dauerbruchstellen sind vorwiegend die Auflagestellen des elastischen Zugbandes auf den Rollen. Infolge der großen Reibung zwischen Zugband und Rolle bilden sich an diesen Stellen Spannungshäufungen, welche den Dauerbruch begünstigen."It is known that the support rollers for the rubber bands are made of hard materials, such as Metal or synthetic resin, to be manufactured or to be composed of rubber and fabric. Endurance breaking points are predominantly the contact points of the elastic drawstring the roles. As a result of the large amount of friction between the drawstring and the roller, they form on them Establish stress accumulations that favor fatigue failure.

Erfindungsgemäß wird diese nachteilige Wirkung dadurch vermieden, daß die Gummirollen gleichmäßig auf den Umfang verteilte, gleich tiefe radiale Ausnehmungen haben, so daß zwischen zwei benachbarten Ausnehmungen in der Richtung der Zugbeanspruchungen des Gummibandes nachgiebige Stützblöcke stehenbleiben, um die Dauert brüche des Gummizugbandes an den Auflagerstellen auf den Rollen zu vermeiden. Wird nunmehr das Band gedehnt, so ist es nicht mehr gezwungen, an den Auflagestellen die volle Dehnungsstrecke zu rutschen, sondern die einzelnen Blöcke haben die Möglichkeit zu kippen und wenigstens eine gewisse Strecke sich mit dem Bande mitzubewegen, so daß Spannungshäufungen an den Auf lagestellen des Gummibandes vermieden werden. Ein weiterer Vorteil besteht darin, daß die innere Reibung der gebogenen Blöcke zu der des • Gummibandes hinzutritt und so eine Vermehrung der Dämpfung bewirkt.According to the invention, this disadvantageous effect is avoided in that the rubber rollers are evenly distributed over the circumference, have the same depth radial recesses, so that between two adjacent Recesses yielding in the direction of the tensile stresses on the rubber band Support blocks stop to last Avoid breaking the elastic band at the support points on the rollers. Will now the tape is stretched, so it is no longer forced to the support points to slide the full stretch, but the individual blocks have the option to tilt and to move at least a certain distance with the gang, so that Accumulations of tension on the support points of the rubber band can be avoided. Another advantage is that the inner Friction of the bent blocks to that of the rubber band adds and thus an increase the damping causes.

Es ist bereits eine in ein Blattfederauge und gleichachsige Lagerbohrungen eingeschobene Gummihülse mit radialen Ausnehmungen bekannt. Bei dieser dienten die Ausnehmungen jedoch nur als Aufnahmeräume für die nicht zusammendrückbare Gummimasse bei der Druckverformung.It is already a rubber sleeve with radial recesses pushed into a leaf spring eye and coaxial bearing bores known. In this case, however, the recesses only served as receiving spaces for the non-compressible rubber mass during compression deformation.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Das Gummiband r ist.um die beiden ebenfalls aus Gummi bestehenden Rollen 2 gelegt, die auf die Bolzen 3 aufgesteckt sind. In den Rollen 2 sind die radialen Ausnehmungen 5 vorgesehen, wodurch, die Außenschicht der Rolle 2 in einzelne achsparallele Blöcke 4 unterteilt ist.An exemplary embodiment of the invention is shown in the drawing. The elastic band r ist.um the two also made of rubber rollers 2 placed on the bolts 3 are attached. In the rollers 2, the radial recesses 5 are provided, whereby the outer layer of the roller 2 is divided into individual axially parallel blocks 4.
