Abstract
Description
Die vorliegende Erfindung betrifft eine Losradachse mit einzeln gelagerten Rädern für Einzel- oder Doppelachs-Fahrwerke von Schienenfahrzeugen, insbesondere von Niederflurfahrzeugen, mit einem U-förmigen, die Räder mit seitlichen Tragschenkeln außen umgreifenden Radtragrahmen, wobei jedes Rad auf der Innenseite des zugehörigen Tragschenkels über eine innerhalb des Rades angeordnete Radlagerung auf einem Achsstummel des Tragschenkels drehbar angelenkt ist, und wobei jedes Rad auf seiner Innenseite drehmomentschlüssig mit einer Welle verbunden ist, die sich durch Öffnungen des Rades und des Tragschenkels nach außen erstreckt.The present invention relates to a Losradachse with individually mounted wheels for single or double axle chassis rail vehicles, in particular low-floor vehicles, with a U-shaped, the wheels with lateral Support legs outside encompassing Radtragrahmen, wherein each wheel on the inside of the associated support leg via a wheel bearing arranged inside the wheel a stub axle of the support leg is rotatably hinged, and wherein each wheel is torque-locked on its inside connected to a shaft extending through openings of the wheel and the support leg extends to the outside.
Eine derartige Losradachse ist in der WO 98/24674 beschrieben. Es handelt sich konkret um eine angetriebene Achse, wobei auf jeder Fahrwerkslängsseite außen am Fahrwerksrahmen ein Antrieb befestigbar ist. Der Antrieb ist - aufgrund einer zwischen dem Tragrahmen und einem dem Antrieb tragenden Fahrwerksrahmen vorgesehenen Primärfederung - über eine kardanische Doppelkupplung mit dem Rad verbunden. Dabei ist eine erste, antriebsseitige Kupplungsebene auf der Außenseite des Antriebs angeordnet und eine zweite, abtriebsseitige Kupplungsebene liegt direkt auf der Innenseite des Rades. Die dadurch als Kardanwelle fungierende Welle verläuft durchgehend mit entsprechender Länge zwischen den beiden Kupplungsebenen der kardanischen Doppelkupplung. Diese bekannte Losradachse hat den Vorteil, daß Achse und Antrieb eine geringe Baubreite haben können, um beispielsweise auch Schmalspur-Fahrzeuge mit gleichzeitig geringer Wagenkastenbreite ohne störenden Überstand der Fahrwerke zu ermöglichen. Ein weiterer Vorteil besteht darin, daß die Lagerung des Rades innerhalb desselben angeordnet ist, wodurch eine gute Tragfähigkeit und hohe Lebensdauer erreicht wird. Diese Lösung ist jedoch dann von Nachteil, wenn eine maximale, lediglich durch den Abstand der Räder sowie notwendige Querfederwege und -freiräume begrenzte Mittelgangbreite (wie z. B, bei Niederflurwagen üblich) verlangt wird, da diese durch die auf der Innenseite des Rades angeordnete Kupplungsebene eingeschränkt wird. Nachteilig kann ebenfalls die durch die Kupplungsebene erschwerte Zugänglichkeit von Radbauteilen, wie z. B. der Radlagerung, für Wartungsarbeiten sein. Außerdem müßte bei einer Anpassung an andere z. B. noch geringere Spurweiten praktisch die gesamte Konstruktion geändert werden.Such a loose wheel axle is described in WO 98/24674. It is concretely a driven axle, being on each chassis longitudinal outside of the chassis frame a drive is fastened. The drive is - due to a between the support frame and a Drive-carrying chassis frame provided primary suspension - via a gimbal double clutch with the wheel connected. Here is a first, drive-side coupling plane arranged on the outside of the drive and a second, output-side clutch plane is located directly on the Inside of the wheel. The thus acting as a propeller shaft Wave runs consistently with appropriate length between the two coupling planes of the gimbal Double coupling. This known Losradachse has the advantage that axis and drive can have a small width, for example, even narrow-gauge vehicles with at the same time small car body width without disturbing projection of the To allow landing gear. Another advantage exists in that the bearing of the wheel within it is arranged, whereby a good load capacity and high Lifespan is reached. However, this solution is then of Disadvantage if a maximum, only by the distance the wheels and necessary transverse suspension paths and clearances Limited aisle width (such as in low-floor wagons usual), as this is due to the inside the wheel arranged coupling plane is limited. The disadvantage can also be hampered by the coupling plane Accessibility of wheel components, such. B. the Wheel bearing, for maintenance work. In addition, should an adaptation to other z. B. even lower gauges virtually the entire design can be changed.
Die DE 44 29 889 A1 beschreibt ein nicht gattungsgemäßes Fahrwerk, bei dem die Räder zusammen mit dem außenseitigen Antrieb außen am Rahmen angeordnet sind. Auch hier sind die Räder mit dem Antrieb über jeweils eine kardanische Doppelkupplung verbunden, wobei aber die abtriebsseitige Kupplungsebene direkt auf der Außenseite des Rades liegt und der Radtragrahmen zwischen den Innenseiten der beiden Räder einer Achse angeordnet ist. Dadurch ist eine Anpassung an unterschiedliche, insbesondere geringere Spurweiten besonders problematisch.DE 44 29 889 A1 describes a non-generic Suspension, in which the wheels together with the outside Drive are arranged outside the frame. Again, these are the Wheels with the drive via one cardan double clutch each connected, but with the output side clutch level lies directly on the outside of the wheel and the wheel support frame between the inner sides of the two wheels an axis is arranged. This is an adaptation to different, in particular smaller gauges especially problematic.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Losradachse der gattungsgemäßen Art zu schaffen, mit der eine besonders gute Anwendungsvariabilität, insbesondere bezüglich der Anpassung an geringere Spurweiten, erreicht wird, bei gleichzeitiger Beibehaltung des Vorteils einer optimalen Auslegung der Radlagerung durch Anordnung derselben innerhalb des Rades. Zudem sollen Wartungsarbeiten erleichtert werden.The present invention is based on the object, a Losradachse of the generic type to create with the a particularly good application variability, in particular in terms of adaptation to lower gauges achieved while maintaining the benefit of one optimal design of the wheel bearing by arranging the same inside the wheel. In addition, maintenance work be relieved.
Erfindungsgemäß wird dies dadurch erreicht, daß die Welle in einer direkt auf der Außenseite des Tragschenkels gebildeten Kupplungsebene endet.According to the invention this is achieved in that the shaft in a directly on the outside of the carrying leg formed coupling plane ends.
Durch diese erfindungsgemäße Maßnahme wird zunächst der Vorteil erreicht, daß für eine Anpassung der Achse an eine andere, z. B. geringere Spurweite (beispielsweise 900 mm) lediglich der das Rad tragende Achsstummel des Tragschenkels und die Welle bezüglich ihrer Länge an die gewünschte, der Spurbreite entsprechende Lage des Rades angepaßt zu werden brauchen. Im Falle einer angetriebenen Achse können alle Antriebskomponenten aber vorteilhafterweise unverändert bleiben, weil dann erfindungsgemäß die Welle eine Antriebs-Zwischenwelle bildet, die in der Kupplungsebene mit einer eigentlichen Antriebswelle verbunden wird. Dadurch kann als Antriebseinheit vorteilhafterweise eine Ausführung verwendet werden, wie sie aus der oben erwähnten DE 44 29 889 A1 bekannt ist. Dennoch werden auch alle Vorteile gemäß der WO 98/24674 beibehalten.By this measure according to the invention is first of Advantage achieved that for an adjustment of the axis to a others, e.g. B. lower gauge (for example, 900 mm) only the wheel stub axle of the support leg and the wave with respect to their length to the desired, matched to the track width corresponding position of the wheel will need. In the case of a driven axle can but all drive components advantageously unchanged stay, because then according to the invention the wave Drive intermediate shaft forms in the coupling plane is connected to an actual drive shaft. This can advantageously as a drive unit Execution can be used as it is from the above DE 44 29 889 A1 is known. Nevertheless, everyone will Maintained advantages according to WO 98/24674.
Darüber hinaus ergibt sich durch die Erfindung der weitere Vorteil, daß bei einer nicht-angetriebenen Achse die Welle als Bremswelle genutzt werden kann, indem sie in der Kupplungsebene mit einer Bremseinrichtung verbunden wird. Die Bremseinrichtung ist mit Vorteil als Scheibenbremse ausgeführt, wobei mit der Bremswelle eine Bremsscheibe verbunden ist, die mit einem am Tragschenkel abgestützten Bremssattel zusammenwirkt.In addition, results from the invention of the other Advantage that in a non-driven axis, the shaft as a brake shaft can be used by putting in the Coupling level is connected to a braking device. The braking device is advantageous as a disc brake executed, with the brake shaft, a brake disc is connected, which supported with a support leg Brake caliper interacts.
Als weiterer Vorteil ist im Sinne eines modularen Systems auch eine Ausführung denkbar, die als Basisvariante zunächst weder Antriebs- noch Bremseinrichtungen aufweist, und bei der das Rad lediglich in der geschilderten Weise am Tragschenkel drehbar angelenkt ist.Another advantage is in the sense of a modular system also a design conceivable as the basic variant first has neither drive nor brake devices, and at the wheel only in the manner described on Support leg is hinged.
Durch Nachrüstung der beschriebenen Welle mit außenliegender Kupplungsebene kann diese dann in eine angetriebene oder gebremste Ausführung überführt werden. Durch dieses "Baukastensystem" kann die Wirtschaftlichkeit der Lösung weiter gesteigert werden.By retrofitting the described shaft with external Coupling plane can then be driven into a or braked execution are transferred. Because of this "Modular system" can increase the cost-effectiveness of the solution be further increased.
Durch die Erfindung sind auch Wartungs- und Reparaturarbeiten schnell und einfach durchführbar, weil alle Komponenten gut zugänglich sind. Dies gilt vor allem für die Radlagerung, die von der Rahmen-Innenseite nahezu frei zugänglich ist, und zwar vorteilhafterweise ohne Demontage des Antriebs. Der Antrieb selbst kann einfach und schnell von der erfindungsgemäßen Zwischenwelle getrennt werden, ohne daß dabei die rahmenseitig befestigten Teil demontiert werden müßten (Rad mit Zwischenwelle). Eine im Falle eines elektrischen Antriebs erforderliche Erdungskontaktanordnung ist bevorzugt am außenseitigen, d. h. vom Rad wegweisenden Ende der erfindungsgemäßen Welle in diese integriert angeordnet. Indem die eigentliche Antriebswelle als Hohlwelle ausgeführt wird, kann auch die Erdungskontaktanordnung gut durch die hohle Antriebswelle hindurch von der Fahrzeugaußenseite erreicht werden. The invention also includes maintenance and repair work fast and easy to carry out, because all Components are easily accessible. This is especially true for the wheel bearing, which is almost free from the frame inside is accessible, and advantageously without disassembly of the drive. The drive itself can be simple and fast be separated from the intermediate shaft according to the invention, without causing the frame-mounted part dismantled would have to be (wheel with intermediate shaft). One in case of one electrical drive required grounding contact arrangement is preferred on the outside, d. H. leading the way from the wheel End of the shaft according to the invention arranged integrated in this. By the actual drive shaft as a hollow shaft is executed, the ground contact arrangement can also be good through the hollow drive shaft through from the vehicle outside be achieved.

In Fig. 1 ist zunächst beispielhaft eine Anwendung von zwei
erf indungsgemäßen Losradachsen 1 in einem angetriebenen
Doppelachsfahrwerk veranschaulicht. Auf jeder Fahrwerkslängsseite
ist dabei eine Antriebseinheit 2 verhanden, die
aus einem Elektromotor 4 und beidseitig angeflanschten
Kegelrad-Getrieben 6 besteht. Jede Achse weist einen U-förmigen
Radtragrahmen 8 auf, der auch unter dem Begriff
Portalachse bekannt ist. An dem Radtragrahmen 8 sind Räder
10 einzeln gelagert, wobei der Radtragrahmen 8 die Räder
mit seitlichen Tragschenkeln 12 außen umgreift und jedes
Rad 10 auf der Innenseite des zugehörigen Tragschenkels 12
drehbar angelenkt ist. Jede Antriebseinheit 2 ist an einem
nicht dargestellten Fahrwerksrahmen aufgehängt, der sich
über eine Primärfederung auf dem jeweiligen Radtragrahmen
8 abstützt. Dazu weist der Radtragrahmen 8 insbesondere im
Bereich der Tragschenkel 12 Auflageflächen 14 für Primärfederelemente
auf. In Fig. 1 is initially an example of an application of two
erf indungsgemäßen Losradachsen 1 in a driven
Double axle landing gear illustrated. On each chassis side
is a
Wie sich nun aus Fig. 2 ergibt, ist jedes Rad 10 auf seiner
Innenseite drehmomentschlüssig mit einer Welle 16 verbunden,
die sich durch Öffnungen des Rades 10 und des
Tragschenkels 12 nach außen erstreckt. Diese Welle 16 endet
erfindungsgemäß in einer direkt auf der Außenseite des
Tragschenkels 12 gebildeten Kupplungsebene 18.As can be seen from Fig. 2, each
Vorzugsweise ist die Welle 16 auf ihrer Innenseite über ein
lösbares Anschlußelement 30 starr mit dem Rad 10 verbunden,
so daß die Welle koaxial mit dem Rad rotiert. Das Rad 10
selbst ist über eine Radlagerung 32 auf einem in das Rad 10
eingreifenden Achsstummel 34 des Tragschenkels 12 gelagert.
Diese Ausgestaltung gewährleistet eine optimale Lagerbeanspruchung
und dadurch eine lange Haltbarkeit der Lager. Die
Welle 16 kann - wie dargestellt - zusätzlich über ein Drehlager
36 in dem Tragschenkel 12 gelagert sein.Preferably, the
Bei dem dargestellten Anwendungsbeispiel einer angetriebenen
Losradachse 1 bildet die Welle 16 eine Antriebs-Zwischenwelle
20, die in der Kupplungsebene 18 über eine
Kupplung 22 mit einer eigentlichen Antriebswelle 24 der
Antriebseinheit 2 verbunden ist. Die Antriebswelle 24 ist
auf ihrer anderen, gegenüberliegenden Seite über eine
weitere Kupplung 26 mit dem Getriebe 6 des Antriebs 2
verbunden. In der bevorzugten Ausgestaltung sind die
Antriebswelle 24 als eine in Verlängerung der Zwischenwelle
im wesentlichen koaxiale, vorzugsweise hohle Kardanwelle
und die zwei beidseitigen Kupplungen 22 und 26 als kardanische
Doppelkupplung ausgeführt. Dabei verläuft die Antriebswelle
24 durch das Getriebe 6 hindurch, so daß eine
antriebsseitige Kupplungsebene 28 auf der vom Tragrahmen 8
wegweisenden Außenseite des Getriebes 6 bzw. des Antriebs
2 liegt, während die abtriebsseitige Kupplungsebene 18 und
die Kupplung 22 zwischen dem Getriebe 6 und dem Tragschenkel
12 des Tragrahmens 8 liegen (vgl. hierzu auch Fig. 1).In the illustrated application example of a driven
Jede Kupplung 22, 26 besteht in an sich bekannter Weise aus
sternförmigen Kupplungsstücken, die unter Zwischenlage von
elastischen, keilartigen Ausgleichselementen ineinandergreifen.
Hierdurch gestatten sie einen kardanischen Ausgleich
von Federungsbewegungen in der Größenordnung von
mindestens ca. ± 15 mm.Each
In weiterer vorteilhafter Ausgestaltung der Erfindung ist
eine Erdungskontaktanordnung 38 an der Welle 16 auf der
Seite der Kupplungsebene 18 integriert angeordnet. Dabei
handelt es sich um eine Schleifkontaktanordnung, um eine
elektrisch leitende Verbindung zwischen rotierenden und
nicht rotierenden Teilen zu gewährleisten. Die Erdungskontaktanordnung
38 ist über eine zentrische, durch die hohl
ausgebildete Welle 16 zur Rad-Innenseite verlaufende
Haltestange 40 und eine sich daran anschließende, horizontale
Drehmomentstütze 42 ortsfest an dem Tragrahmen 8
abgestützt. Dabei kann zwischen der hohlen Welle 16 und der
Haltestange 40 wenigstens ein Drehlager 44 angeordnet sein,
und zwar insbesondere im inneren, etwa in der Ebene des
Rades 10 liegenden Bereich. Bei dieser bevorzugten Anordnung
der Erdungskontaktanordnung 38 ist es zudem vorteilhaft,
wenn die hohle Antriebswelle 24 auf ihrer von der
Zwischenwelle 20 wegweisenden Außenseite eine - vorzugsweise
mit einem lösbaren Deckelelement 46 verschließbare -
Revisionsöffnung 48 für die in die Zwischenwelle 20 integrierte
Erdungskontaktanordnung 38 aufweist.In a further advantageous embodiment of the invention

Bremswelle genutzt werden, indem sie in der Kupplungsebene
18 mit einer Bremseinrichtung verbunden wird. Bei dieser
nicht dargestellten Alternative ist dann die Bremseinrichtung
bevorzugt als Scheibenbremse ausgeführt, wobei mit der
Welle 16 eine Bremsscheibe verbunden ist, so daß diese
gemeinsam mit dem Rad 10 rotiert. Die Bremsscheibe wirkt
