Description

Stoßdämpfer, insbesondere zum Einbau in das Gehäuse einer Zugvorrichtung für Eisenbahnwagen Die Erfindung bezieht sich auf einen insbesondere zum Einbau in das Gehäuse einer Zugvorrichtung für Eisenbahnwagen bestimmten Stoßdämpfer mit einem elastischen Ringkörper, dessen Hohlraum mit einem nichtelastischen fließfähigen Dämpfungsstoff gefüllt ist.Shock absorbers, especially for installation in the housing of a pulling device for railway carriages The invention relates to a particular one for installation in the housing of a pulling device for railway carriages with certain shock absorbers an elastic ring body, the cavity of which with a non-elastic flowable Damping material is filled.

Die Erfindung sieht eine Ausbildung eines solchen Stoßdämpfers vor, bei welcher die Dämpfungswirkung dadurch vergrößert wird, daß erfindungsgemäß der Hohlraum in an sich bekannter Weise an seinen Stirnflächen durch ebene Verstärkungsplatten abgeschlossen ist, von denen wenigstens eine einen in den Hohlraum einspringenden Verdrängeransatz für die Füllung aufweist.The invention provides for a design of such a shock absorber, in which the damping effect is increased by the fact that according to the invention Cavity in a manner known per se at its end faces by means of flat reinforcing plates is completed, of which at least one re-entrant into the cavity Has displacer approach for the filling.

Durch eine solche Ausbildung wird die Verdrängung der Füllung nach außen verstärkt und damit die Dämpfungswirkung vergrößert. Erfindungsgemäß kann der Verdrängeransatz zweckmäßig an einem in der Verstärkungsplatte sitzenden Füllverschluß vorgesehen sein. Ferner wird man, um den Fließvorgang bei der Verdrängung des Dämpfungsstoffes zu unterstützen, vorteilhafterweise den Verdrängeransatz mit abgerundeten oder schrägen Kanten versehen.Such a training the displacement of the filling according to Reinforced on the outside and thus the damping effect increased. According to the invention can the displacer attachment is expediently attached to a filler cap seated in the reinforcement plate be provided. Furthermore, one becomes to the flow process in the displacement of the damping material to support, advantageously the displacer approach with rounded or inclined Provide edges.

Die Erfindung wird an Hand der Zeichnung erläutert, welche in Schnittdarstellungen einen erfindungsgemäß ausgebildeten Stoßdämpfer im Ruhezustand (F i g. 1) sowie im belasteten Zustand (F i g. 2) zeigt.The invention is explained with reference to the drawing, which is in sectional views a shock absorber designed according to the invention in the idle state (FIG. 1) and shows in the loaded state (F i g. 2).

Der Stoßdämpfer besteht aus einem elastischen Ringkörper 2, dessen Hohlraum mit einem nichtelastischen fließfähigen Dämpfungsstoff wie z. B. Asphalt, Sand, Wachs oder einer Asphalt-Sand-Mischung gefüllt ist. Diese Füllung ist in der Zeichnung nicht wiedergegeben.The shock absorber consists of an elastic ring body 2, whose Cavity with a non-elastic flowable damping material such. B. asphalt, Filled with sand, wax or a mixture of asphalt and sand. This filling is in the Drawing not reproduced.

Der Hohlraum 16 ist an seinen Stirnflächen durch ebene Verstärkungsplatten 8,10 abgeschlossen, die mit dem Ringkörper durch Klebung verbunden sein können. Der Ringkörper 2 besteht aus Gummi oder einem gummiartigen Stoff, während die Verstärkungsplatten 8,10 aus Metall bestehen können. Der Ringkörper weist ein konkav einspringendes Profil auf, was dann wünschenswert ist, wenn der Stoßdämpfer z. B. in das Gehäuse einer Zugvorrichtung für Eisenbahnwagen eingesetzt wird.The cavity 16 is at its end faces by flat reinforcing plates 8,10 completed, which can be connected to the ring body by gluing. The ring body 2 is made of rubber or a rubber-like material, while the reinforcing plates 8,10 can be made of metal. The ring body has a concave re-entrant Profile on what is desirable when the shock absorber z. B. in the housing a pulling device for railroad cars is used.

Um das Einfüllen des Dämpfungsstoffes zu ermöglichen, ist in der Verstärkungsplatte 8 eine Gewindeöffnung vorgesehen, in welche ein Füllverschluß 18 eingeschraubt werden kann. Dieser Verschluß kann Vertiefungen 24 aufweisen, in welche ein entsprechendes Werkzeug zum Festziehen und Lösen des Verschlusses eingesetzt werden kann.In order to allow the filling of the damping material is in the reinforcement plate 8 a threaded opening is provided into which a filler cap 18 is screwed can. This closure can have recesses 24 in which a corresponding Tool for tightening and loosening the closure can be used.

Bei Belastung des Stoßdämpfers wird der Dämpfungsstoff in der Kammer 16 nach außen verdrängt, wobei diese Verdrängung dadurch verstärkt wird, daß einerseits an dem Füllverschluß 18 und andererseits an der unteren Verstärkungsplatte je ein in den Hohlraum 16 einspringender, mit abgeschrägten Kanten 28 versehener Verdrängeransatz 26 bzw. 30 vorgesehen ist. Anstatt der abgeschrägten Kanten 28 kann der Verdrängeransatz mit abgerundeten Kanten ausgebildet sein oder eine halbkugelförmige Gestalt annehmen.If a load of the shock absorber, the damping material is in the chamber 16 displaces outwards, this displacement is enhanced by the fact that on the one hand to the filling cap 18 and on the other hand to the lower reinforcing plate, a re-entrant into the cavity 16, provided with bevelled edges 28 Verdrängeransatz 26 depending or 30 is provided.. Instead of the beveled edges 28, the displacer attachment can be designed with rounded edges or assume a hemispherical shape.
