Definitions
- the invention relates to a chassis according to the preamble of claim 1.
- the rocker comprises the axle and is mounted approximately over its entire width on the car body, namely by the rocker is supported at both ends to the car body out.
- the invention has for its object to improve a generic chassis to the effect that this allows a sinusoidal running of the wheels.
- the invention proposes, in other words, not to support the rocker at their ends on the car body, so close to the two sides of the car body, rather the rocker is proposed to be supported centrally on the car body.
- This central support on the car body allows due to the ever-present game in the camps the minimum of lateral mobility, which allows the two wheels of the chassis the sinusoidal on the rails.
- the rocker can be centrally supported by means of a horizontally arranged pull and push rod centrally on the car body in order to absorb forces in the longitudinal direction of the rail vehicle in this way.
- the rocker be supported in its central region via an upright torque arm on the car body to initiate the upright forces in this way in the car body can.
- a transmission between the two wheels may be arranged in a manner known per se in order to transmit driving forces to the axle, which forms the so-called wheel set together with the two wheels, so that for this reason the transmission is also referred to as wheelset transmission .
- this gearbox transmission can advantageously be provided a horizontally arranged torque arm, which the forces occurring in the longitudinal direction in the car body initiates, in which case this torque arm is supported centrally on the car body.
- a collision-free guidance of the individual elements of the proposed chassis are thereby made possible, at the same time as compact dimensions of the entire arrangement that the torque arms of the rocker on the one hand and the transmission on the other hand penetrate each other.
- one of these two torque arms is provided with an opening through which extends the other of the two torque arms.
- 1 designates a total chassis, which is arranged on a rail vehicle below a car body 2.
- the chassis 1 includes, inter alia, a wheelset in the form of an axle which carries two wheels 3. Between the wheels 3, a wheelset gear 4 is arranged, which serves to drive the axle, wherein the axis itself is not directly apparent in the drawings, but indicated at 5.
- the two ends of the axis 5 are guided by a rocker 6, wherein the rocker 6 has a cross member 7 which is parallel to the axis 5, and which carries at its two ends in each case a swing arm 8, which extends in the direction of the axis 5.
- the upper bearing 9 serves to support an upright torque arm 12, wherein the pull-push rod 11 and this upright torque arm 12 serve to support the rocker 6.
- the upright torque arm 12 extends centrally under the car body 2, so that both the train-push rod 11 and the torque arm 12, the rocker 6 is supported centrally on the car body 2 and accordingly allows low oscillations of the axis 5, which ultimately a sinusoidal allow the wheels 3 on the rails.
- the upright torque arm 12 forms an opening 14 through which a lying oriented torque arm 15 extends, which is articulated on the one hand on the wheelset gear 4 and on the other hand is supported centrally on the car body 2.
- the upright torque arm 12 of the rocker 6 to a component which is configured in one piece and the opening 14 framed.
- the upright rocker 6 could have two separate struts, which leave a distance between them, which serves as an opening 14 and makes it possible to pass the lying torque arm 15 of the transmission 4 through this opening 14.
- the opening 14 may be realized in the horizontal torque arm 15 of the transmission 4, so that in such a case, the upright torque arm 12 of the rocker 6 would not have the opening 14 shown, but rather even through the opening of the lying Torque arm 15 would be guided.
- chassis 1 essentially known constructions, so that it need not be discussed in detail.
- brake disks 16 arranged between the wheels 3 and the wheel set transmission 4 and to the rocker suspension 17 of the running wheels 3 and to the wheelset bearings 18 at the ends of the axle 5.
- connection plates 19 which each connect to the car body 2.
- the carbody 2 is equipped with a supporting frame. Then the connection is not made to body elements of the car body 2, but rather to the frame of the respective rail vehicle.
- very different rail vehicles can be created using identical or similar frames, so that the term of the car body generally includes different structures on the frame, these structures need not necessarily be designed in the form of a closed box.

Abstract
Bei einem Fahrwerk (1) eines einen Wagenkasten (2) aufweisenden Schienenfahrzeugs, mit zwei um eine gemeinsame Achse (5) drehbaren Rädern, und einer die Achse führenden Schwinge (6), wobei die Schwinge um eine parallel zur Achse verlaufende Schwenkachse schwenkbeweglich gelagert ist, derart, dass sie die Achse höhenbeweglich führt, und wobei die Schwinge am Wagenkasten abgestützt ist, schlägt die Erfindung vor, dass die Schwinge mittig am Wagenkasten abgestützt ist.In a chassis (1) of a vehicle body (2) having rail vehicle, with two about a common axis (5) rotatable wheels, and an axis leading rocker (6), wherein the rocker is pivotally mounted about a pivot axis extending parallel to the axis in such a way that it leads the axle to be movable in height, and with the rocker being supported on the car body, the invention proposes that the rocker is supported centrally on the car body.
Description
Die Erfindung betrifft ein Fahrwerk nach dem Oberbegriff des Anspruchs 1.The invention relates to a chassis according to the preamble of claim 1.
Aus der
Während mit einer solch breiten Lagerung der Schwinge eine besonders präzise Führung der Räder ermöglicht ist, kann genau dieser Umstand in der Praxis problematisch sein: Wenn die Räder hochpräzise stets an derselben Stelle über die Schienen des Gleises laufen, tritt an genau dieser Stelle ein erhöhter Verschleiß an den Schienen auf. Es wird daher ein so genannter Sinuslauf bevorzugt, bei dem die Räder während ihrer Abrollbewegung quer zum Gleis auf der Schiene langsam hin und her pendeln, so dass die Schiene über ihre jeweilige Breite gesehen möglichst gleichmäßig abgenutzt wird und ein verstärkter Verschleiß der auf einen schmalen Abschnitt des Schienenprofils beschränkt ist, vermieden werden kann.While with such a wide bearing of the rocker a particularly precise guidance of the wheels is possible, this fact can be problematic in practice: If the wheels always run with high precision always in the same place on the rails of the track, occurs at this point increased wear on the rails. It is therefore preferred a so-called sinusoidal, in which the wheels during their rolling movement transversely to the track on the rail slowly oscillate back and forth, so that the rail over their respective width seen worn as evenly as possible and increased wear on a narrow section of the rail profile is limited, can be avoided.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Fahrwerk dahingehend zu verbessern, dass dieses einen Sinuslauf der Räder ermöglicht.The invention has for its object to improve a generic chassis to the effect that this allows a sinusoidal running of the wheels.
Diese Aufgabe wird durch ein Fahrwerk mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.This object is achieved by a chassis with the features of claim 1. Advantageous embodiments are described in the subclaims.
Die Erfindung schlägt mit anderen Worten vor, die Schwinge nicht an ihren Enden am Wagenkasten abzustützen, also nahe den beiden Seiten des Wagenkastens, vielmehr soll die Schwinge vorschlagsgemäß mittig am Wagenkasten abgestützt werden. Diese mittige Abstützung am Wagenkasten ermöglicht aufgrund des stets vorhandenen Spiels in den Lagern das Minimum an seitlicher Beweglichkeit, welches den beiden Rädern des Fahrwerks den Sinuslauf auf den Schienen ermöglicht.The invention proposes, in other words, not to support the rocker at their ends on the car body, so close to the two sides of the car body, rather the rocker is proposed to be supported centrally on the car body. This central support on the car body allows due to the ever-present game in the camps the minimum of lateral mobility, which allows the two wheels of the chassis the sinusoidal on the rails.
Vorteilhaft kann die Schwinge in ihrem mittleren Bereich mittels einer liegend angeordneten Zug- und Druckstange mittig am Wagenkasten abgestützt sein, um auf diese Weise Kräfte in Längsrichtung des Schienenfahrzeugs aufzunehmen.Advantageously, the rocker can be centrally supported by means of a horizontally arranged pull and push rod centrally on the car body in order to absorb forces in the longitudinal direction of the rail vehicle in this way.
Vorteilhaft kann die Schwinge in ihrem mittleren Bereich über eine aufrecht angeordnete Drehmomentstütze am Wagenkasten abgestützt sein, um die aufrechten Kräfte auf diese Weise in den Wagenkasten einleiten zu können.Advantageously, the rocker be supported in its central region via an upright torque arm on the car body to initiate the upright forces in this way in the car body can.
Vorteilhaft kann in an sich bekannter Weise ein Getriebe zwischen den beiden Rädern angeordnet sein, um Antriebskräfte auf die Achse zu übertragen, die zusammen mit den beiden Rädern den so genannten Radsatz bildet, so dass aus diesem Grunde das Getriebe auch als Radsatz-Getriebe bezeichnet wird. Auch für dieses Radsatz-Getriebe kann vorteilhaft eine liegend angeordnete Drehmomentstütze vorgesehen sein, welche die in Längsrichtung auftretenden Kräfte in den Wagenkasten einleitet, wobei auch in diesem Fall diese Drehmomentstütze mittig am Wagenkasten abgestützt ist.Advantageously, a transmission between the two wheels may be arranged in a manner known per se in order to transmit driving forces to the axle, which forms the so-called wheel set together with the two wheels, so that for this reason the transmission is also referred to as wheelset transmission , Also for this gearbox transmission can advantageously be provided a horizontally arranged torque arm, which the forces occurring in the longitudinal direction in the car body initiates, in which case this torque arm is supported centrally on the car body.
Vorteilhaft kann eine kollisionsfreie Führung der einzelnen Elemente des vorgeschlagenen Fahrwerks dadurch ermöglicht werden, bei gleichzeitig möglichst kompakten Abmessungen der gesamten Anordnung, dass die Drehmomentstützen der Schwinge einerseits und des Getriebes andererseits einander durchdringen. Zu diesem Zweck ist eine dieser beiden Drehmomentstützen mit einer Öffnung versehen, durch welche sich die andere der beiden Drehmomentstützen erstreckt.Advantageously, a collision-free guidance of the individual elements of the proposed chassis are thereby made possible, at the same time as compact dimensions of the entire arrangement that the torque arms of the rocker on the one hand and the transmission on the other hand penetrate each other. For this purpose, one of these two torque arms is provided with an opening through which extends the other of the two torque arms.

In den Zeichnungen ist mit 1 insgesamt ein Fahrwerk bezeichnet, welches an einem Schienenfahrzeug unterhalb eines Wagenkastens 2 angeordnet ist. Das Fahrwerk 1 enthält u. a. einen Radsatz in Form einer Achse, welche zwei Laufräder 3 trägt. Zwischen den Laufrädern 3 ist ein Radsatz-Getriebe 4 angeordnet, welches zum Antrieb der Achse dient, wobei die Achse selbst in den Zeichnungen nicht direkt ersichtlich, aber bei 5 angedeutet ist. Die beiden Enden der Achse 5 sind durch eine Schwinge 6 geführt, wobei die Schwinge 6 eine Traverse 7 aufweist, die parallel zur Achse 5 verläuft, und die an ihren beiden Enden jeweils einen Schwingenarm 8 trägt, welcher sich in Richtung der Achse 5 erstreckt.In the drawings, 1 designates a total chassis, which is arranged on a rail vehicle below a
Vor dem Getriebe 4 sind zwei Lager 9 und 10 ersichtlich. Vom unteren Lager 10 aus erstreckt sich eine Zug-Druckstange 11 nach vorn, wo sie mittig unter dem Wagenkasten 2 an den Wagenkasten 2 anschließt, über eine in den Zeichnungen nicht dargestellte Konsole.Before the
Das obere Lager 9 dient zur Lagerung einer aufrecht verlaufenden Drehmomentstütze 12, wobei die Zug-Druckstange 11 und diese aufrechte Drehmomentstütze 12 zur Abstützung der Schwinge 6 dienen. Auch die aufrechte Drehmomentstütze 12 erstreckt sich mittig unter den Wagenkasten 2, so dass sowohl über die Zug-Druckstange 11 als auch über die Drehmomentstütze 12 die Schwinge 6 mittig am Wagenkasten 2 abgestützt ist und dementsprechend geringe Pendelbewegungen der Achse 5 ermöglicht, die letztlich einen Sinuslauf der Laufräder 3 auf den Schienen zulassen.The upper bearing 9 serves to support an
Die aufrechte Drehmomentstütze 12 bildet eine Öffnung 14, durch welche sich eine liegend ausgerichtete Drehmomentstütze 15 erstreckt, die einerseits am Radsatz-Getriebe 4 angelenkt ist und sich andererseits am Wagenkasten 2 mittig abstützt.The
Sämtliche Fahrwerkskomponenten, die in den
Bei dem dargestellten Ausführungsbeispiel weist die aufrechte Drehmomentstütze 12 der Schwinge 6 ein Bauteil auf, welches einteilig ausgestaltet ist und die Öffnung 14 umrahmt. Abweichend dazu könnte die aufrechte Schwinge 6 zwei separate Streben aufweisen, die zwischen sich einen Abstand lassen, welcher als Öffnung 14 dient und es ermöglicht, die liegende Drehmomentstütze 15 des Getriebes 4 durch diese Öffnung 14 hindurchzuführen.In the illustrated embodiment, the
Weiterhin könnte in Abwandlung des dargestellten Ausführungsbeispiels die Öffnung 14 in der liegenden Drehmomentstütze 15 des Getriebes 4 verwirklicht sein, so dass in einem solchen Fall die aufrechte Drehmomentstütze 12 der Schwinge 6 nicht die dargestellte Öffnung 14 aufweisen müsste, sondern vielmehr selbst durch die Öffnung der liegenden Drehmomentstütze 15 geführt würde.Furthermore, in a modification of the illustrated embodiment, the
Im Übrigen entspricht die Ausgestaltung des in den
Im Rahmen des vorliegenden Vorschlags ist der Wagenkasten 2 erläutert worden, an den das Fahrwerk 1 anschließt. Der Anschluss der Drehmomentstützen 12 und 15 sowie der Zug-Druckstange 11 erfolgt dabei über Anschlussplatten 19, die jeweils an den Wagenkasten 2 anschließen. Typischerweise ist der Wagenkasten 2 mit einem tragenden Rahmen ausgestattet. Dann erfolgt der Anschluss nicht an Karosserieelemente des Wagenkastens 2, sondern vielmehr an den Rahmen des jeweiligen Schienenfahrzeugs. Durch diesen Aufbau des Schienenfahrzeugs können unter Verwendung gleicher oder ähnlicher Rahmen sehr unterschiedliche Schienenfahrzeuge geschaffen werden, so dass der Begriff des Wagenkastens ganz allgemein unterschiedliche Aufbauten auf dem Rahmen miteinschließt, wobei diese Aufbauten nicht notwendigerweise in Form eines geschlossenen Kastens ausgeführt sein müssen.In the context of the present proposal, the
