Description

Die Erfindung betrifft ein Fahrwerk für ein Schienenfahrzeug, mit zumindest einem Fahrwerksrahmen und zumindest einem innengelagerten ersten Räderpaar.The invention relates to a running gear for a rail vehicle, having at least one running gear frame and at least one first pair of wheels mounted on the inside.

Sensoren von Zugsicherungssystemen wie Antennen oder Auslösehebel für Fahrsperren müssen gemäß ihrer Spezifikation in Fahrtrichtung eines Schienenfahrzeuges möglichst weit vorne und in vertikaler Richtung nahe über einer Schienenoberkante angebracht werden. Bei Schienenfahrzeugen mit außengelagerten Fahrwerken können Zugsicherungssensoren auf einem Langträger eines Fahrwerksrahmens angeordnet werden. Bei innengelagerten Fahrwerken ist das häufig nur schwer möglich, da nach dem Prinzip der Innenlagerung der Langträger des Fahrwerksrahmens innerhalb von Räderpaaren verläuft und außenliegende Räder eine unmittelbare Anbindung von Zugsicherungssensoren an einer Vorderseite des Fahrwerks verhindern.According to their specification, sensors of train protection systems such as antennas or release levers for travel locks must be attached as far forward as possible in the direction of travel of a rail vehicle and in the vertical direction close to the top edge of the rail. In the case of rail vehicles with externally mounted bogies, train protection sensors can be arranged on a longitudinal beam of a bogie frame. In the case of internally mounted bogies, this is often difficult to do because, according to the principle of internal mounting, the solebar of the bogie frame runs within pairs of wheels and external wheels prevent train protection sensors from being directly connected to a front side of the bogie.

Ferner ist aus denselben Gründen eine Anbindung von Stromabnehmern sowie weiterer Komponenten, in deren Auslegung vertikale Bewegungen gegenüber einer Schienenoberkante berücksichtigt werden müssen, nur schwer möglich.Furthermore, for the same reasons, it is difficult to connect pantographs and other components whose design must take into account vertical movements relative to the upper edge of the rail.

Aus dem Stand der Technik ist z.B. das innengelagerte Siemens-Fahrwerk SF7000 bekannt.For example, the Siemens SF7000 bogie with internal bearings is known from the prior art.

Der genannte Ansatz weist in seiner bekannten Form den Nachteil auf, dass Zugsicherungssensoren, Stromabnehmer etc. aufgrund der Innenlagerung und aufgrund des Fehlens von entsprechenden Vorrichtungen im Bereich der Räder nicht in der Nähe einer Schienenoberkante angeordnet werden können.In its known form, the stated approach has the disadvantage that train protection sensors, pantographs, etc. cannot be arranged near a rail top edge due to the internal storage and due to the lack of corresponding devices in the area of the wheels.

Weiterhin ist die WO 00/64721 A2 bekannt, welche ein Niederflur-Schienenfahrzeug mit innengelagerten Triebfahrwerken offenbart. Diese innengelagerten Triebfahrwerke weisen Antriebs-Getriebeeinheiten auf, welche mit Fahrwerksrahmen und Rädern bzw. Radsätzen verbunden sind. Der genannte Ansatz weist in seiner bekannten Form den Nachteil auf, dass Zugsicherungssensoren, Stromabnehmer etc. nur im Bereich angetriebener Räder (auf den Antriebs-Getriebeeinheiten) in der Nähe einer Schienenoberkante angeordnet werden können.Furthermore, the WO 00/64721 A2 known, which discloses a low-floor rail vehicle with internally mounted traction units. These internally stored Motorized bogies have drive gear units which are connected to the bogie frame and wheels or wheelsets. In its known form, the stated approach has the disadvantage that train protection sensors, pantographs, etc. can only be arranged in the area of driven wheels (on the drive gear units) in the vicinity of a rail top edge.

Ferner zeigt die US 2 636 451 A ein Fahrwerk für ein Schienenfahrzeug sowie eine Dämpfungsvorrichtung zwischen dem Fahrwerk und einem Wagenkasten.Furthermore, the U.S. 2,636,451 A a chassis for a rail vehicle and a damping device between the chassis and a car body.

Ein Gehäuse einer Gleitschutzvorrichtung ist drehbar an einem Ende einer Radsatzwelle gelagert und mittels eines Arms gegen Verdrehungen gesichert. Der Arm ist wiederum elastisch mit einem Fahrwerksrahmen verbunden.A housing of an anti-skid device is rotatably mounted on one end of a wheelset shaft and secured against twisting by means of an arm. The arm is in turn elastically connected to a chassis frame.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Fahrwerk anzugeben.The invention is therefore based on the object of specifying a running gear that is improved over the prior art.

Erfindungsgemäß wird diese Aufgabe gelöst mit einem Fahrwerk nach Anspruch 1.According to the invention, this object is achieved with a chassis according to claim 1.

Durch diese Maßnahme wird der Vorteil erzielt, dass Schnittstellenkomponenten wie Stromabnehmer oder Zugsicherungssensoren etc. in der Nähe einer Bahninfrastruktur angeordnet werden können und somit eine Interaktion dieser Schnittstellenkomponenten mit in Außenbereichen von Gleisen, beispielsweise in einem Gleiskörper vorgesehenen Zugsicherungseinrichtungen erleichtert wird.This measure has the advantage that interface components such as pantographs or train protection sensors etc. can be arranged in the vicinity of a railway infrastructure and thus interaction of these interface components with train protection devices provided in the outer areas of tracks, for example in a track body, is facilitated.

Weiterhin ergibt sich aufgrund der Position der Adapterschwinge auf dem Fahrwerk eine günstige Flexibilität hinsichtlich der auf der Adapterschwinge vorzusehenden Komponenten. Auf der Adapterschwinge ist zumindest eine, als Stromabnehmer, als Enteisungseinrichtung, als Überwachungseinrichtung für eine Stromschiene oder als Zugsicherungssensor ausgeführte Komponente angeordnet.Furthermore, due to the position of the adapter rocker on the chassis, there is favorable flexibility with regard to what is to be provided on the adapter rocker components. At least one component designed as a current collector, as a de-icing device, as a monitoring device for a power rail or as a train protection sensor is arranged on the adapter rocker.

Eine günstige Lösung ergibt sich, wenn die Adapterschwinge mit einer Längssteifigkeit an den Fahrwerksrahmen angebunden ist, welche Relativbewegungen zwischen dem Fahrwerksrahmen und dem zumindest ersten Räderpaar zulässt.A favorable solution results when the adapter rocker is connected to the chassis frame with a longitudinal rigidity which allows relative movements between the chassis frame and at least the first pair of wheels.

Durch diese Maßnahme werden Einschränkungen von Freiheitsgraden des Fahrwerks gemindert.This measure reduces restrictions on the degrees of freedom of the chassis.

Eine vorteilhafte Ausgestaltung erhält man, wenn zumindest eine auf der Adapterschwinge angeordnete Komponente über ein Befestigungsmittel vertikal verstellbar ausgeführt ist. Durch diese Maßnahme ergibt sich eine günstige Flexibilität hinsichtlich einer Anpassung der Komponente an verschiedene Ausführungsformen und Konstruktionseigenschaften von Fahrwerken sowie an Eigenschaften einer entsprechenden Bahninfrastruktur (z.B. bei einer Ausführung der Komponente als Stromabnehmer).An advantageous embodiment is obtained if at least one component arranged on the adapter rocker is designed to be vertically adjustable via a fastening means. This measure results in favorable flexibility with regard to adapting the component to different designs and design properties of running gear as well as to properties of a corresponding railway infrastructure (e.g. when the component is designed as a pantograph).

Es ist günstig, wenn zumindest eine Komponente in einer Weise auf der Adapterschwinge angeordnet ist, dass die Funktionen der zumindest einen Komponente verträglich mit den Relativbewegungen zwischen der Adapterschwinge und dem ersten Rad sind.It is favorable if at least one component is arranged on the adapter rocker in such a way that the functions of the at least one component are compatible with the relative movements between the adapter rocker and the first wheel.

Durch diese Maßnahme wird der Vorteil eines annähernd konstanten Relativabstands zwischen der Komponente und einer Schienenoberkante erzielt. Dies ist insbesondere wichtig, wenn die Komponente als Schnittstellenkomponente zu einer Bahninfrastruktur ausgeführt ist.This measure achieves the advantage of an approximately constant relative distance between the component and a top edge of the rail. This is particularly important if the component is used as an interface component to a railway infrastructure is implemented.

Es ist vorteilhaft, wenn zumindest eine Komponente in einer Weise auf der Adapterschwinge angeordnet ist, dass dieIt is advantageous if at least one component is arranged on the adapter rocker in such a way that the

Funktionen der zumindest einen Komponente mit den Funktionen von anderen Komponenten des Fahrwerks verträglich sind. Durch diese Maßnahmen wird vermieden, dass sich Komponenten des Fahrwerks gegenseitig stören, z.B. eine Magnetschienenbremse durch ein elektromagnetisches Feld die Signalübertragung einer Zugsicherungsantenne beeinflusst. Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.Functions of at least one component are compatible with the functions of other components of the chassis. These measures prevent components of the running gear from interfering with one another, for example a magnetic track brake affecting the signal transmission of a train protection antenna through an electromagnetic field. The invention is explained in more detail below using exemplary embodiments.

Ein in Fig. 1 dargestellter Grundriss zeigt eine erste, beispielhafte Variante eines erfindungsgemäßen Fahrwerks für ein Schienenfahrzeug.a in 1 illustrated floor plan shows a first exemplary variant of a chassis according to the invention for a rail vehicle.

Das Fahrwerk umfasst einen Fahrwerksrahmen 1 mit einem innengelagerten ersten Räderpaar 14 und einem innengelagerten zweiten Räderpaar 15, die als Radsätze ausgeführt sind.The running gear comprises a running gear frame 1 with a first pair of wheels 14 mounted on the inside and a second pair of wheels 15 mounted on the inside, which are designed as wheelsets.

Fig. 1 zeigt einen Längsschnitt durch den Fahrwerksrahmen 1, wobei der Längsschnitt ein erstes Rad 2 und ein zweites Rad 3 aufweist. 1 shows a longitudinal section through the chassis frame 1, the longitudinal section having a first wheel 2 and a second wheel 3.

Das Fahrwerk umfasst eine erste Radsatzwelle 4 und eine zweite Radsatzwelle 5. Über eine erste Radsatzlagereinheit 6 ist die erste Radsatzwelle 4 und über eine zweite Radsatzlagereinheit 7 die zweite Radsatzwelle 5 drehbar mit dem Fahrwerksrahmen 1 verbunden. Die erste Radsatzlagereinheit 6 und die zweite Radsatzlagereinheit 7 weisen je ein Radsatzlager mit einem Radsatzlagergehäuse auf. Eine Adapterschwinge 8 ist auf einem in Fig. 1 rechts gezeigten Bereich an einer Außenseite des Fahrwerks angeordnet.The running gear comprises a first wheelset shaft 4 and a second wheelset shaft 5. The first wheelset shaft 4 is rotatably connected to the running gear frame 1 via a first wheelset bearing unit 6 and the second wheelset shaft 5 is connected via a second wheelset bearing unit 7. The first wheel set bearing unit 6 and the second wheel set bearing unit 7 each have a wheel set bearing with a wheel set bearing housing. An adapter rocker 8 is on an in 1 The area shown on the right is arranged on an outside of the chassis.

Sie ist über ein Drehgelenk 9 in einem mittleren Bereich des Fahrwerks mit dem Fahrwerksrahmen 1 verbunden. Die Längssteifigkeit des Drehgelenks 9 ist gering und somit vorteilhaft, weil dadurch Relativbewegungen zwischen dem ersten Rad 2 und der ersten Radsatzwelle 4 in Richtung einer Längsachse 13 ermöglicht werden.It is connected to the chassis frame 1 via a swivel joint 9 in a central region of the chassis. The longitudinal rigidity of the rotary joint 9 is low and is therefore advantageous because it allows relative movements between the first wheel 2 and the first wheelset axle 4 in the direction of a longitudinal axis 13 .

An dem in Fig. 1 rechts dargestellten Ende der Adapterschwinge 8 ist eine Schwingenlagereinheit 10 angeordnet.on the in 1 A swing arm bearing unit 10 is arranged at the end of the adapter swing arm 8 shown on the right.

Die Schwingenlagereinheit 10 umfasst ein Schwingenlager, das als Wälzlager ausgeführt ist und einen Stummel des ersten Rads 2 drehbar mit der Schwingenlagereinheit 10 verbindet. Auf der Adapterschwinge 8 ist auf einer in Fig. 1 rechts gezeigten Seitenfläche der Schwingenlagereinheit 10 ein Zugsicherungssensor, d.h. eine Schnittstellenkomponente zu einer Bahninfrastruktur angeordnet.The rocker bearing unit 10 includes a rocker bearing that is designed as a roller bearing and rotatably connects a stub of the first wheel 2 to the rocker bearing unit 10 . On the adapter rocker 8 is on an in 1 shown on the right side surface of the rocker bearing unit 10, a train protection sensor, ie arranged an interface component to a railway infrastructure.

Diese ist als vertikal nach unten gerichteter Auslösehebel 11 einer Fahrsperre für ein Zugsicherungssystem ausgeführt.This is designed as a vertically downward-pointing release lever 11 of a travel lock for a train protection system.

Die Seitenfläche weist nicht dargestellte Befestigungsmittel mit einer Zahnplatte auf, über die der Auslösehebel 11 in seiner vertikalen Position verstellbar ist. Weiterhin weisen die Befestigungsvorrichtungen Elastikelemente auf, die den Auslösehebel 11 mechanisch von der Adapterschwinge 8 entkoppeln.The side surface has fastening means (not shown) with a toothed plate, via which the release lever 11 can be adjusted in its vertical position. Furthermore, the fastening devices have elastic elements that mechanically decouple the release lever 11 from the adapter rocker arm 8 .

Die Anordnung des Auslösehebels 11 auf der Seitenfläche der Schwingenlagereinheit 10 ist vorteilhaft, da an dieser Stelle der Adapterschwinge 8 die Relativbewegungen zwischen dem ersten Rad 2 und der Adapterschwinge 8 bzw. dem Auslösehebel 11 gering sind.The arrangement of the release lever 11 on the side face of the rocker bearing unit 10 is advantageous since at this point of the adapter rocker 8 the relative movements between the first wheel 2 and the adapter rocker 8 or the release lever 11 are small.

Der Relativabstand zwischen dem Auslösehebel 11 und einer nicht dargestellten Schiene, auf der das erste Rad 2 und das zweite Rad 3 abrollen, bzw. dem Gleiskörper bleibt annähernd konstant. Dadurch ist von dem Auslösehebel 11 ein in dem Gleiskörper angeordneter Streckenanschlag des Zugsicherungssystems mit großer Sicherheit erreichbar.The relative distance between the release lever 11 and a rail, not shown, on which the first wheel 2 and the second wheel 3 roll, or the track remains approximately constant. As a result, a route stop of the train protection system arranged in the track body can be reached with great certainty by the release lever 11 .

Fig. 2 zeigt die in Fig. 1 dargestellte erste Variante eines erfindungsgemäßen Fahrwerks als Seitenriss. 2 shows the in 1 illustrated first variant of a chassis according to the invention as a side view.

Ein in Fig. 3 dargestellter Grundriss zeigt eine zweite, beispielhafte Variante eines erfindungsgemäßen Fahrwerks mit Innenlagerung für ein Schienenfahrzeug.a in 3 The floor plan shown shows a second exemplary variant of a chassis according to the invention with internal storage for a rail vehicle.

Im Unterschied zu jener Ausführungsvariante, die in Fig. 1 gezeigt wird, weist eine in Fig. 3 dargestellte Adapterschwinge 8 auf einer Unterseite einen als Zugsicherungsantenne 12 ausgeführten Zugsicherungssensor, d.h. eine Schnittstellenkomponente zu einer Bahninfrastruktur auf.In contrast to the embodiment variant in 1 is shown has an in 3 shown adapter rocker 8 on a bottom designed as a train protection antenna 12 train protection sensor, ie an interface component to a railway infrastructure.

Zwischen der Unterseite der Adapterschwinge 8 und der Zugsicherungsantenne 12 sind nicht dargestellte Befestigungsmittel mit Elastikelementen und Beilagen angeordnet. Diese bewirken einerseits eine mechanische Entkopplung der Zugsicherungsantenne 12 von der Adapterschwinge 8 und führen andererseits zu einer vertikalen Verstellbarkeit der Zugsicherungsantenne 12.Between the underside of the adapter rocker arm 8 and the train control antenna 12, fastening means, not shown, with elastic elements and inserts are arranged. On the one hand, these cause a mechanical Decoupling of the train protection antenna 12 from the adapter rocker 8 and, on the other hand, lead to a vertical adjustability of the train protection antenna 12.

Die Form der Adapterschwinge 8 sowie die Anordnung der Zugsicherungsantenne 12 darauf sind flexibel und somit vorteilhaft. Interaktionen mit anderen Komponenten des Fahrwerks (beispielsweise nicht dargestellte Magnetschienenbremsen) können auf diese Weise vermieden werden.The shape of the adapter rocker 8 and the arrangement of the train protection antenna 12 on it are flexible and therefore advantageous. Interactions with other components of the running gear (for example magnetic rail brakes, not shown) can be avoided in this way.

Im Übrigen entspricht das dargestellte Prinzip jener Ausführungsvariante, die in Fig. 1 gezeigt wird.For the rest, the principle shown corresponds to the embodiment variant shown in 1 will be shown.

Fig. 4 zeigt einen Seitenriss der in Fig. 3 dargestellten, zweiten Variante eines erfindungsgemäßen Fahrwerks. 4 shows a side elevation of the in 3 illustrated, second variant of a chassis according to the invention.

Bei den in den Fig. 1, Fig. 2, Fig. 3 und Fig. 4 auf einer Adapterschwinge 8 angeordneten Zugsicherungssensoren handelt es sich um günstige Lösungen. Erfindungsgemäß ist es jedoch auch möglich, auf der Adapterschwinge 8 beispielsweise einen Stromabnehmer, eine Enteisungseinrichtung, die beispielsweise als Enteisungsbürste oder als Flüssigenteisungsanlage ausgeführt sein kann, eine Überwachungseinrichtung für eine Stromschiene oder eine Bremse etc. anzuordnen.At the in the Figure 1, Figure 2 , 3 and 4 train protection sensors arranged on an adapter rocker 8 are favorable solutions. According to the invention, however, it is also possible to arrange a current collector, a de-icing device, for example a de-icing brush or a liquid de-icing system, a monitoring device for a conductor rail or a brake, etc. on the adapter rocker 8 .
