Bedämpfung erforderlich. Damping required.
Um die einzelnen Fahrwerkskomponenten am Wagenkasten zu mon tieren, ist meist eine Bearbeitung der Aufnahmepunkte am Wa genkasten erforderlich. Für den Bearbeitungsvorgang wird ein entsprechend umfangreicher Bearbeitungsplatz benötigt. Hier für ist ein erheblicher technischer Aufwand notwendig. In order to mount the individual chassis components on the body, machining of the mounting points on the body is usually necessary. A correspondingly extensive machining station is required for the machining process. This requires considerable technical effort.
Für die genannten Montagevarianten ist mithin ein erheblicher Aufwand nötig. A considerable effort is therefore necessary for the mounting variants mentioned.
Es besteht also die Aufgabe, eine Vorrichtung und ein Verfah ren anzugeben, mit denen eine Anbindung von Fahrwerkskompo nenten an ein Untergestell eines Schienenfahrzeugs mit redu ziertem Aufwand ermöglicht wird. There is therefore the task of specifying a device and a method with which a connection of chassis components to a base of a rail vehicle is made possible with reduced expenditure.
Diese Aufgabe wird durch einen Schienenfahrzeug-Radsatz zwischenrahmen gemäß Patentanspruch 1, ein Schienenfahrzeug gemäß Patentanspruch 7 und ein Verfahren zum Herstellen eines Schienenfahrzeug-Radsatzzwischenrahmens gemäß Patentanspruch 8 gelöst. This object is achieved by a rail vehicle wheel set intermediate frame according to claim 1, a rail vehicle according to claim 7 and a method for producing a rail vehicle wheel set intermediate frame according to claim 8.

In einer speziellen Variante des erfindungsgemäßen Schienen- fahrzeug-Radsatzzwischenrahmens weist dieser eine beliebige Kombination der zuvor genannten Schnittstellen auf. In a special variant of the rail vehicle wheel set intermediate frame according to the invention, this has any combination of the aforementioned interfaces.
Der erfindungsgemäße Schienenfahrzeug-Radsatzzwischenrahmen kann derart dimensioniert sein, dass der Schienenfahrzeug- Radsatzzwischenrahmen wesentlich kleiner als der Wagenkasten ausgebildet ist. Vorteilhaft lässt sich der Schienenfahrzeug- Radsatzzwischenrahmen leichter bearbeiten als ein erheblich größer dimensionierter Wagenkasten. Insbesondere sind z.B. einzelne Bohrungen für Schnittstellen für Fahrwerkkomponenten leichter exakt zu positionieren als in einem groß dimensio nierten Wagenkasten, da z.B. die dafür genutzten Werkzeuge und Messeinrichtungen kleiner dimensioniert sein können. The rail vehicle wheel set intermediate frame can be dimensioned in such a way that the rail vehicle wheel set intermediate frame is designed to be substantially smaller than the car body. The rail vehicle wheel set intermediate frame is advantageously easier to machine than a considerably larger car body. In particular, e.g. Individual holes for interfaces for chassis components can be positioned more easily than in a large car body, e.g. the tools and measuring equipment used for this can be dimensioned smaller.

In FIG 1 ist eine schematische Seitenansicht eines unteren Bereichs eines Eisenbahnfahrzeugs 10 mit einem Schienenfahr- zeug-Radsatzzwischenrahmen 2, auch kurz als Radsatzzwischen rahmen oder Zwischenrahmen bezeichnet, gemäß einem Ausfüh rungsbeispiel der Erfindung gezeigt. Das Eisenbahnfahrzeug 10 weist einen Wagenkasten mit einem Untergestell 3 auf, das als Tragestruktur sowohl für ein Fahrwerk als auch für Aufbauten genutzt wird. Das Untergestell weist sogenannte Längsträger 3a auf, an denen die Radsatzzwischenrahmen 2 an Schnittstel len 2c fixiert sind. Ein solcher Radsatzzwischenrahmen 2 weist eine Vielzahl von weiteren Schnittstellen 4a, 4b, 4c, 4d, 4e auf, an denen unterschiedliche Fahrwerkskomponenten 5, 6, 7, 8, 9 montiert sind. An Federungsschnittstellen 4a des Radsatzzwischenrahmens 2 sind Federelemente 5 mit einem ers ten Ende 5a fixiert. Ein zweites Ende 5b der Federungselemen te 5 ist mit einem Achslager 7a verbunden. Das Federungsele ment 5 wird durch einen Stoßdämpfer 6 ergänzt, welcher z.B. seitlich betrachtet zwischen den beiden Federungselementen 5 eines Rads 1 angeordnet ist. Der Stoßdämpfer 6 dämpft ein Schwingungsverhalten der Federungselemente 5, um so einen un unterbrochenen Kontakt der Räder 1 mit einer Schiene auf rechtzuerhalten. Die Stoßdämpfer 6 sind jeweils mit einem En de an einer Stoßdämpferschnittstelle 4b des Radsatzzwischen rahmens 2 montiert und mit einem zweiten Ende mit einem Achs lager 7a verbunden. Der Radsatz bestehend aus Achsen 7 und Rädern 1 wird von einer sogenannten Längsmitnahme 8 in Längs richtung stabilisiert. Die Längsmitnahme 8 weist z.B. eine Stange 8a auf, deren eines Ende 8b mit dem Achslager 7a eines Rades 1 verbunden ist und deren zweites Ende 8c mit einem Längsmitnahmeträger 4c verbunden ist. Der Längsmitnahmeträger 4c ist seinerseits an dem Radsatzzwischenrahmen 2 fixiert.

Such a wheel set intermediate frame 2 has a large number of further interfaces 4a, 4b, 4c, 4d, 4e, on which different chassis components 5, 6, 7, 8, 9 are mounted. At suspension interfaces 4a of the wheelset intermediate frame 2, spring elements 5 are fixed with a first end 5a. A second end 5b of the Federungselemen te 5 is connected to an axle bearing 7a. The Federungsele element 5 is supplemented by a shock absorber 6, which is arranged, for example, viewed laterally between the two suspension elements 5 of a wheel 1. The shock absorber 6 dampens a vibration behavior of the suspension elements 5, so as to maintain an uninterrupted contact of the wheels 1 with a rail. The shock absorbers 6 are each mounted with an end on a shock absorber interface 4b of the wheel set intermediate frame 2 and connected with a second end to an axle bearing 7a. The wheelset consisting of axles 7 and Wheels 1 is stabilized by a so-called longitudinal entrainment 8 in the longitudinal direction. The longitudinal driver 8 has, for example, a rod 8a, one end 8b of which is connected to the axle bearing 7a of a wheel 1 and the second end 8c of which is connected to a longitudinal driver carrier 4c.
