Description

Die Erfindung betrifft einen Schienenfahrzeug-Radsatzzwischenrahmen. Überdies betrifft die Erfindung ein Schienenfahrzeug.The invention relates to a rail vehicle wheel set intermediate frame. The invention also relates to a rail vehicle.

Werden Radsätze ohne Drehgestellrahmen direkt an einem Wagenkasten eines Schienenfahrzeugs montiert, so sind die erforderlichen Toleranzen der Anbindungspunkte sehr klein und die Anzahl der Anbindungspunkte ist sehr groß. Beispielsweise sind Anbindungspunkte für die Längsmitnahme, die Federung, die Antriebsaufhängung, die Bremseinrichtung und die Bedämpfung erforderlich.If wheelsets are mounted directly on a car body of a rail vehicle without a bogie frame, the required tolerances of the connection points are very small and the number of connection points is very large. For example, connection points for the longitudinal driving, the suspension, the drive suspension, the braking device and the damping are required.

Um die einzelnen Fahrwerkskomponenten am Wagenkasten zu montieren, ist meist eine Bearbeitung der Aufnahmepunkte am Wagenkasten erforderlich. Für den Bearbeitungsvorgang wird ein entsprechend umfangreicher Bearbeitungsplatz benötigt. Hierfür ist ein erheblicher technischer Aufwand notwendig.In order to mount the individual running gear components on the car body, it is usually necessary to process the mounting points on the car body. A correspondingly extensive processing station is required for the processing operation. This requires considerable technical effort.

Für die genannten Montagevarianten ist mithin ein erheblicher Aufwand nötig.A considerable amount of effort is therefore necessary for the installation variants mentioned.

Aus der Druckschrift DE 102014117047 A1 ist eine Traverse für Schienenfahrzeuge zur Anlenkung eines Wagenkastens eines Schienenfahrzeugs an dessen Drehgestell bekannt.From the pamphlet DE 102014117047 A1 a traverse for rail vehicles for articulating a car body of a rail vehicle on its bogie is known.

Aus der Druckschrift DE 19825858 A1 ist ein Wagen für ein Schienenfahrzeug bekannt. Eine Wagenkastenzelle ist mit Verbindungsmitteln für ein darunter angeordnetes Laufwerk versehen. Um eine vereinfachte Schnittstelle zwischen Wagenkastenzelle und Laufwerk zu erzielen, ist ein Zwischenrahmen vorgesehen, der starr mit der Wagenkastenzelle verbunden und auf dem Laufwerk abgestützt ist.From the pamphlet DE 19825858 A1 a carriage for a rail vehicle is known. A car body cell is provided with connection means for a running gear arranged underneath. In order to achieve a simplified interface between the car body structure and the running gear, an intermediate frame is provided which is rigidly connected to the car body structure and supported on the running gear.

Es besteht also die Aufgabe, eine Vorrichtung anzugeben, mit denen eine Anbindung von Fahrwerkskomponenten an ein Untergestell eines Schienenfahrzeugs mit reduziertem Aufwand ermöglicht wird.There is therefore the task of specifying a device with which a connection of running gear components to a subframe of a rail vehicle is made possible with reduced effort.

Diese Aufgabe wird durch einen Schienenfahrzeug-Radsatzzwischenrahmen gemäß Patentanspruch 1 und durch ein Schienenfahrzeug gemäß Patentanspruch 5 gelöst.This object is achieved by a rail vehicle wheel set intermediate frame according to patent claim 1 and by a rail vehicle according to patent claim 5 .

Der erfindungsgemäße Schienenfahrzeug-Radsatzzwischenrahmen weist eine Mehrzahl von Montageschnittstellen für Fahrwerckomponenten an vorbestimmten Positionen auf. Ein Fahrwerk kann dabei alle Bauelemente umfassen, die der Verbindung des Fahrgestells bzw. des Wagenkastens über die Räder zu den Schienen oder der Wechselwirkung der Räder mit den Schienen dienen. Die Mehrzahl von Montageschnittstellen sind an der Unterseite des Zwischenrahmens, d.h. auf der dem Boden zugewandten Seite des Zwischenrahmens, bei bestimmungsgemäßer Anordnung des Zwischenrahmens, angeordnet. Vorteilhaft lassen sich die Mehrzahl von Montageschnittstellen direkt an dem platzsparenden Zwischenrahmen ausbilden, so dass keine groß dimensionierten Bearbeitungsplätze notwendig sind. Der erfindungsgemäße Schienenfahrzeug-Radsatzzwischenrahmen weist mindestens eine definierte Montageschnittstelle zur Fixierung an einem Untergestell eines Wagenkastens eines Schienenfahrzeugs auf. Die definierte Montageschnittstelle ist an den Seiten oder der Oberseite des Zwischenrahmens, d.h. der vom Boden abgewandten Seite des Zwischenrahmens angeordnet. Die Anordnung der Radsätze, d.h. der Fahrwerkkomponenten wird durch die Einführung des Zwischenrahmens stark vereinfacht, da nur die Zwischenrahmen zueinander, aber nicht eine Vielzahl von Einzelschnittstellen zueinander an dem Untergestell des Wagenkastens positioniert werden müssen. Die Positionierung der einzelnen Fahrwerkskomponenten relativ zu dem Untergestell bzw. dem Wagenkasten kann sehr leicht durch z.B. die Ausbildung einer gemeinsamen Schnittstelle zwischen dem Zwischenrahmen und dem Untergestell des Wagenkastens oder durch Ausrichten der Zwischenrahmen erfolgen.The rail vehicle wheel set intermediate frame according to the invention has a plurality of assembly interfaces for chassis components at predetermined positions. A running gear can include all components that are used to connect the chassis or the car body via the wheels to the rails or the interaction of the wheels with the rails. The plurality of assembly interfaces are arranged on the underside of the intermediate frame, ie on the side of the intermediate frame facing the floor when the intermediate frame is arranged as intended. Advantageously, the majority of assembly interfaces can be formed directly on the space-saving intermediate frame, so that no large-scale processing stations are necessary. The rail vehicle wheel set intermediate frame according to the invention has at least one defined assembly interface for fixing to an underframe of a car body of a rail vehicle. The defined mounting interface is arranged on the sides or the top of the intermediate frame, ie the side of the intermediate frame facing away from the floor. The arrangement of the wheel sets, ie the running gear components, is greatly simplified by the introduction of the intermediate frame, since only the intermediate frames have to be positioned relative to one another, but not a large number of individual interfaces relative to one another on the underframe of the car body. The individual running gear components can be positioned relative to the underframe or the car body very easily, for example by forming a common interface between the intermediate frame and the underframe of the car body or by aligning the intermediate frames.

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 dimensionierten Wagenkasten, da z.B. die dafür genutzten Werkzeuge und Messeinrichtungen kleiner dimensioniert sein können.The rail vehicle wheel set intermediate frame according to the invention can be dimensioned in such a way that the rail vehicle wheel set intermediate frame is designed to be significantly smaller than the car body. Advantageously, the rail vehicle wheel set intermediate frame can be processed more easily than a significantly larger carriage body. In particular, individual bores for interfaces for chassis components are easier to position precisely than in a large-dimensioned car body, since the tools and measuring devices used for this can be smaller.

Die Erfindung wird im Folgenden unter Hinweis auf die beigefügten Figuren anhand von Ausführungsbeispielen noch einmal näher erläutert. Es zeigen:

In FIG 1 ist eine schematische Seitenansicht eines unteren Bereichs eines Eisenbahnfahrzeugs 10 mit einem Schienenfahrzeug-Radsatzzwischenrahmen 2, auch kurz als Radsatzzwischenrahmen oder Zwischenrahmen bezeichnet, gemäß einem Ausführungsbeispiel 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 Schnittstellen 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 ersten Ende 5a fixiert. Ein zweites Ende 5b der Federungselemente 5 ist mit einem Achslager 7a verbunden. Das Federungselement 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 ununterbrochenen Kontakt der Räder 1 mit einer Schiene aufrechtzuerhalten. Die Stoßdämpfer 6 sind jeweils mit einem Ende an einer Stoßdämpferschnittstelle 4b des Radsatzzwischenrahmens 2 montiert und mit einem zweiten Ende mit einem Achslager 7a verbunden. Der Radsatz bestehend aus Achsen 7 und Rädern 1 wird von einer sogenannten Längsmitnahme 8 in Längsrichtung 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. Weiterhin ist eine Scheiben- oder Klotzbremse 9 über eine Bremsschnittstelle 4d mit dem Radsatzzwischenrahmen 2 verbunden. Angedeutet ist in FIG 1 auch eine Antriebsschnittstelle 4e, welche ebenfalls an dem Zwischenrahmen 2 montiert ist.In FIG 1 1 is a schematic side view of a lower area of a railway vehicle 10 with a rail vehicle wheel set intermediate frame 2, also referred to as wheel set intermediate frame or intermediate frame for short, according to an exemplary embodiment of the invention. The railway vehicle 10 has a car body with an underframe 3, which is used as a support structure both for a chassis and for superstructures. The underframe has so-called longitudinal beams 3a, on which the intermediate wheel set frames 2 are fixed at interfaces 2c. Such an intermediate wheel set frame 2 has a multiplicity 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 wheel set intermediate frame 2 spring elements 5 are fixed with a first end 5a. A second end 5b of the spring elements 5 is connected to an axle bearing 7a. The suspension element 5 is supplemented by a shock absorber 6 which, for example, is arranged between the two suspension elements 5 of a wheel 1 when viewed from the side. The shock absorber 6 dampens a vibration behavior of the suspension elements 5 so as to maintain uninterrupted contact of the wheels 1 with a rail. The shock absorbers 6 are each mounted with one end on a shock absorber interface 4b of the wheel set intermediate frame 2 and are 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 carrier 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 carrier 4c. The longitudinal carrier 4c is in turn fixed to the wheel set intermediate frame 2 . Furthermore, a disc brake or block brake 9 is connected to the wheel set intermediate frame 2 via a brake interface 4d. is indicated in FIG 1 also a drive interface 4e, which is also mounted on the intermediate frame 2.
