Description

Gummifeder, insbesondere für Drehgestelle von Schienenfahrzeugen Die Erfindung bezieht sich auf eine Gummifeder, insbesondere für Drehgestelle von Schienenfahrzeugen, bestehend aus einem glockenförmigen Metallgehäuse und einem kegelförmigen Dom, wobei in dem zwischen dem Gehäuse und dem Dom gebildeten Raum ein ringförmiger Gummikörper angeordnet ist.Rubber springs, in particular for bogies of rail vehicles The invention relates to a rubber spring, in particular for bogies of rail vehicles, consisting of a bell-shaped metal housing and a conical dome, whereby an annular rubber body in the space formed between the housing and the dome is arranged.

Bei den Gummifedern der eingangs genannten Art sind der Dom und die Glocke aus Metall gefertigt, deren dem Gummikörper anliegende Flächen zur Einhaltung der Federcharakteristik einer genauen Bearbeitung bei voller Beachtung der vorgeschriebenen Durchmessermaße und den nur geringen zulässigen Toleranzen unterworfen sind. Um diese kostspielige mechanische Bearbeitung zu vermindern, ist es bekannt, den Dorn und die Glocke im Guß- oder Schweißverfahren herzustellen und die Flächen zu glätten. Dieses Verfahren ist wegen der Erstellung teurer und komplizierter Formen aufwendig und macht eine Nachbearbeitung erforderlich, damit die Genauigkeit der Berührungsflächen in Form und Durchmesser gewährleistet ist. überdies erhöht die massive Ausführung in Metall das Gewicht der Feder.In the rubber springs of the type mentioned are the dome and the Bell made of metal, the surfaces of which lie against the rubber body for compliance the spring characteristics of a precise machining with full compliance with the prescribed Diameter dimensions and the only small permissible tolerances are subject. Around To reduce this costly machining, it is known to use the mandrel and to manufacture the bell in a casting or welding process and to smooth the surfaces. This method is laborious because of the production of expensive and complicated shapes and requires post-processing to improve the accuracy of the contact surfaces is guaranteed in shape and diameter. it also increases the massive execution in metal the weight of the spring.

Der Erfindung liegt die Aufgabe zugrunde, die erwähnten Nachteile zu vermeiden und eine Gummifeder zu schaffen, bei der jede Nachbearbeitung der Berührungsflächen entfällt, so daß die Fertigungszeit erheblich verkürzt und die Erstellung weitaus weniger aufwendig wird. überdies soll das Gesamtgewicht der Gummifeder erheblich herabgesetzt werden.The invention is based on the mentioned disadvantages to avoid and to create a rubber spring with any post-processing of the contact surfaces omitted, so that the production time is shortened considerably and the creation by far becomes less expensive. In addition, the total weight of the rubber spring should be considerable be reduced.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß der Dorn aus einem Metallkern mit einem Kunststoffmantel besteht und das glockenförmige Metallgehäuse mit einer Auskleidung aus Kunststoff versehen ist.According to the invention, this object is achieved in that the mandrel consists of a metal core with a plastic jacket and the bell-shaped metal housing is provided with a plastic lining.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt schematisch dargestellt. Der Dorn 1 besteht aus einem Metallkern 2, dessen Basis 2 a nach den jeweiligen Erfordernissen in verschiedener Abmessung ausgeführt und mit Ausnehmungen für Schraubverbindungen od. dgl. ausgestattet sein kann sowie aus einem auf ihm fest sitzenden Kunststoffmantel 3, dessen äußere Fläche 3 a jeweils entsprechend der gewünschten Federcharakteristik gestaltet ist. Die Glocke 4 besteht aus einer Abdeckung 4 a aus Metall, die eine mittig angeordnete Ausnehmung 4 b trägt und einem mit der Ab- deckung 4 a verbundenen metallischen Zylinder 4 c, dessen Innenseite mit einer Auskleidung 5 aus Kunststoff versehen ist. Die Federcharakteristik wird nur durch die besondere Formgebung des Kunststoffes der Auskleidung erreicht. Sowohl beim Dom 1 als auch bei der Glocke 4 ist die Verbindung zwischen Kunststoff und Metall kraftschlüssig und kann weder durch die während des Betriebes auftretenden Temperatureinflüsse gelöst werden, noch kann eine statische Aufladung des Kunststoffes durch Reibung erfolgen. Die zu übertragenden Kräfte werden demnach über den Gummikörper 6 auf den Kunststoff und sodann von dem Metall als kräftetragendes Material übernommen.In the drawing, an embodiment of the invention is shown schematically in longitudinal section. The mandrel 1 consists of a metal core 2, the base 2 a of which can be designed in different dimensions according to the respective requirements and equipped with recesses for screw connections or the like, as well as a plastic jacket 3 firmly seated on it, the outer surface 3 a of which is correspondingly in each case the desired spring characteristics is designed. The bell 4 is composed of a cover 4 a metal, which carries a centrally disposed recess 4 b and a connected metallic cylinder 4 c with the cover 4, the inside of which is provided with a liner 5 made of plastic. The spring characteristic is only achieved through the special shape of the plastic lining. In both the dome 1 and the bell 4, the connection between plastic and metal is non-positive and cannot be loosened by the temperature influences occurring during operation, nor can the plastic be statically charged by friction. The forces to be transmitted are accordingly taken over by the rubber body 6 on the plastic and then by the metal as the force-bearing material.

Die Kunststoffschicht kann mit Hilfe einer leicht herzustellenden Form mit den Metallteilen verbunden werden, wobei hierzu ein Formkem für die Glocke 4 und eine Hohlform für den Dorn 1 Verwendung finden. Die Oberflächen des Kunststoffes können auf Grund der Beschaffenheit der Herstellungsformen glatt oder aufgerauht sein.The plastic layer can be connected to the metal parts with the aid of a mold that is easy to manufacture, a mold core for the bell 4 and a hollow mold for the mandrel 1 being used for this purpose. The surfaces of the plastic can be smooth or roughened due to the nature of the production forms.
