Description

Gegenstand der vorliegenden Erfindung betrifft ein Eisenbeton-Untergestell für Eisenbahnwagen.The present invention relates to a reinforced concrete frame for Railroad car.

Eisenbeton-Untergestelle für Eisenbahnwagen sind an sich bekannt, haben sich jedoch nicht bewährt, weil die bei den bisherigen Konstruktionen verwendeten inneren Streben und Träger durch die auftretenden Stöße brechen oder sich verbiegen.Reinforced concrete underframes for railroad cars are known per se, but have become not proven because of the internal struts used in previous designs and beams break or bend due to the impacts occurring.

ίο Diesen übelstand beseitigt die vorliegende Erfindung, die auf beiliegender Zeichnung in einem Ausführungsbeispiel, und zwar in einer Ansicht, dargestellt ist.ίο The present eliminates this evil Invention, which is based on the accompanying drawing in one embodiment, namely in a View, is shown.

Das neue Eisenbeton-Untergestell umfcerscheidet sich grundlegend von den bisher im Wagenbau verwendeten Konstruktionen und besteht aus einem einzigen, zusammenhänhängenden, im Grundriß vollständig geschlossenen elastischen und biiegungsfesten sogenannten Rahmen, der durch die beiden Stirnträger S1 und S2 und durch die beiden Längsträger L1 und L2 gebildet wird. Zur Aufnahme der senkrechten Lasten (Frachtgut, Ladegut) würde eine über den Rahmen gelegte einfache Platte genügen. Die Platte kann mit dem Rahmen auch fest verbunden sein. Betriebskräfte wesentlicher Art dürfen durch diese Platte nicht aufgenommen und nicht übertragen werden. Zu diesem Zwecke und auch aius wirtschaftlichen Gründen werden innere Längs- und Querträger α und b verwendet, deren Stege vom Rahmen durch Einschalten eines Hohlraumes oder eines elastischen Zwischenstückes getrennt werden, um die Wirkungsweise des Rahmens in keiner Weise zu beeinflussen und zu behindern. Der Erfinder hat sich mit seiner Erfindung über alle bisher im Eisenbahnbetrieb gewonnenen Erfahrungen hinwegsetzt. Als seitheriges charakteristisches und unentbehrlich erscheinendes Merkmal eines Eisenbahnwagen-Untergestelles galt die strebenartige Anordnung und gelenkige Verbindung der einzelnen Teile. Die Bauformen und insbesondere die Abmessungen der einzelnen Konstruktionsteile der hölzernen und der heute vorherrschenden eisernen Wagentypen sind in diesem Sinne vorwiegend auf empirischem Wege und durch immerwährendes Probieren und Abändern entwickelt worden. Diese Bauform hat der Erfinder vollkommen verlassen.The new reinforced concrete subframe is fundamentally different from the constructions previously used in wagon construction and consists of a single, coherent, elastic and bend-resistant so-called frame that is completely closed in plan, which is formed by the two end members S 1 and S 2 and the two longitudinal members L 1 and L 2 is formed. A simple plate placed over the frame would suffice to accommodate the vertical loads (freight, cargo). The plate can also be firmly connected to the frame. Significant operating forces may not be absorbed or transferred by this plate. For this purpose and also for economic reasons, inner longitudinal and cross members α and b are used, the webs of which are separated from the frame by switching on a cavity or an elastic intermediate piece, so as not to affect or hinder the operation of the frame in any way. With his invention, the inventor disregarded all previous experience gained in railway operations. Since then, the strut-like arrangement and articulated connection of the individual parts has been considered a characteristic and seemingly indispensable feature of a railroad car underframe. The designs and especially the dimensions of the individual structural parts of the wooden and the iron wagon types that are predominant today have been developed in this sense mainly on an empirical basis and through constant trial and error. The inventor has completely abandoned this design.
