Description

Achsantrieb für ein Schienenfahrzeug Final drive for a rail vehicle
Die Erfindung betrifft das Gebiet der Schienenfahrzeuge. Sie betrifft insbesondere einen Achsantrieb hierfür.The invention relates to the field of rail vehicles. It particularly relates to an axle drive for this purpose.
Ein solcher Achsantrieb umfasst eine Laufradsatzwelle. Auf jedem Ende der Laufradsatzwelle sitzt ein Laufrad, das mit der Welle drehfest verbunden ist. Die Lauf radsatzwelle ist von einem Motor angetrieben. Die Drehachsen von Laufradsatzwelle und Motor verlaufen parallel zueinander. Zwischen Motor und Laufradsatzwelle ist ein Getriebe geschaltet. Das Getriebe befindet sich zwischen einem der beiden Räder und dem Motor. Es umfasst ein großes Zahnrad, das auf die Laufradsatzwelle aufgekeilt ist, sowie ein Ritzel, das auf die Motorwelle aufgekeilt ist. Ritzel und Zahnrad kämmen miteinander. Ritzel und Zahnrad sind von einem Gehäuse umschlossen.Such a final drive comprises a wheelset shaft. On each end of the wheelset shaft sits an impeller which is rotatably connected to the shaft. The wheelset shaft is driven by a motor. The axes of rotation of the wheelset shaft and motor are parallel to each other. Between the engine and the wheelset shaft, a transmission is connected. The gearbox is located between one of the two wheels and the engine. It includes a large sprocket keyed onto the sprocket set shaft and a sprocket keyed onto the motor shaft. Pinion and gear mesh with each other. Pinion and gear are enclosed by a housing.
Es kann im Verlaufe der Lebensdauer eines solchen Achsantriebes zu einem Blockieren des Rotors des Motors kommen. Dies ist eine schwierige Situation für das Wartungspersonal, da das Schienenfahrzeug, somit die Lokomotive, nicht mehr mit eigenem Antrieb fahrtüchtig ist. Es bleibt somit nur das Abschleppen des Schienenfahrzeuges, was außerordentlich aufwendig ist, wenn sich das Fahrzeug auf der Strecke befindet.It can come in the course of the life of such a final drive to block the rotor of the motor. This is a difficult situation for the maintenance staff, since the rail vehicle, thus the locomotive, is no longer roadworthy with its own drive. Thus, it remains only the towing the rail vehicle, which is extremely expensive when the vehicle is on the track.
Will man das Abschleppen vermeiden, so bleibt nur als Ausweg, die Triebverbindung zwischen dem Motor und der Laufradsatzwelle zu unterbrechen. Auch dies ist schwierig und aufwendig, da hierzu der Motor vom übrigen Laufradsatz abmontiert werden muss.If you want to avoid towing, so only as a way to interrupt the drive connection between the engine and the wheelset shaft. Again, this is difficult and expensive, since this engine must be removed from the rest of the wheelset.
Der Erfindung liegt die Aufgabe zugrunde, einen Achsantrieb der eingangs beschriebenen Art derart zu gestalten, dass ein Entkoppeln von Motor und Laufradsatzwelle leicht und schnell durchführbar ist.The invention has for its object to make a final drive of the type described above such that a decoupling of motor and wheelset shaft is easy and fast to carry out.
Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst. Der Erfinder hat einen verblüffend einfachen Weg gefunden. Demgemäß lässt sich das Getriebegehäuse im Bereich des Ritzels auf der Seite des dort befindlichen Laufrades öffnen. Die Weite des Zwischenraumes zwischen dem Ritzel und dem Laufrad ist im Allgemeinen wenigstens gleich der Länge des Ritzels. Das Ritzel ist von der Motorwelle leicht abziehbar und in den Zwischenraum verbringbar. Damit ist die drehfeste Verbindung zwischen Ritzel und Laufradsatzwelle des Motors gelöst, und zugleich die Triebverbindung zwischen Motor und Laufradsatzwelle aufgehoben. Das Ritzel kann nunmehr provisorisch in dem Zwischenraum gehalten werden. Die Blockade des gesamten Fahrzeuges durch den schadhaften Antrieb ist aufgehoben, und das Fahrzeug kann mit Hilfe weiterer Antriebe aus eigener Kraft weiterfahren.This object is solved by the features of claim 1. The inventor has found a surprisingly simple way. Accordingly, the gear housing can be opened in the region of the pinion on the side of the impeller located there. The width of the gap between the pinion and the impeller is generally at least equal to the length of the pinion. The pinion is easily removable from the motor shaft and can be moved into the intermediate space. Thus, the rotationally fixed connection between the pinion and wheelset shaft of the engine is released, and at the same time repealed the drive connection between the engine and Laufradsatzwelle. The pinion can now be provisionally held in the gap. The blockage of the entire vehicle due to the faulty drive is canceled, and the vehicle can drive on its own with the help of further drives.
Gemäß einem weiterführenden Gedanken sind Vorkehrungen getroffen, um das Ritzel nach dem Abziehen von der Motorwelle und nach dem Verbringen in denAccording to a further idea precautions are taken to the pinion after the removal of the motor shaft and after the spill into the
Zwischenraum auch noch in Laufradialer Richtung zu verschieben, und zwar senkrecht zur Laufradsatzwelle des Achsantriebes über den Außenumfang desAlso to move gap in the radial direction, perpendicular to the wheelset shaft of the final drive over the outer circumference of
Laufrades hinaus. In dieser Position lässt es sich durch weiteres Verschieben parallel zur Achse der Laufradsatzwelle entnehmen.Impeller out. In this position, it can be removed by further displacement parallel to the axis of the wheelset shaft.
Der Stand der Technik sowie die Erfindung sind anhand der Zeichnung näher erläutert. Darin ist im Einzelnen Folgendes dargestellt:The prior art and the invention are explained in more detail with reference to the drawing. It details the following:
Figur 1 zeigt einen konventionellen Achsantrieb mit Blickrichtung auf die Achse der Laufradsatzwelle.Figure 1 shows a conventional axle drive with a view towards the axis of the wheelset shaft.
Figur 2 zeigt den Gegenstand von Figur 1 in einer Draufsicht.Figure 2 shows the article of Figure 1 in a plan view.
Figur 3 zeigt einen erfindungsgemäßen Achsantrieb, wiederum mit Blickrichtung auf die Achse der Laufradsatzwelle.Figure 3 shows a final drive according to the invention, again with a view towards the axis of the wheelset shaft.
Figur 4 zeigt den Gegenstand von Figur 3 in Draufsicht; Figur 5 zeigt wiederum einen erfindungsgemäßen Achsantrieb analog jenem gemäß der Figuren 3 und 4, jedoch mit weiteren Einzelheiten.Figure 4 shows the article of Figure 3 in plan view; FIG. 5 again shows an axle drive according to the invention analogous to that according to FIGS. 3 and 4, but with further details.
Der in Figur 1 gezeigte konventionelle Achsantrieb weist eine Laufradsatzwelle 1 auf. Die Laufradsatzwelle trägt zwei Räder 2, 3, mit denen sie drehfest verbunden ist. Es ist ein Antriebsmotor 4 vorgesehen. Dessen Drehachse 4.1 verläuft parallel zur Drehachse 1.1 der Laufradsatzwelle.The conventional final drive shown in Figure 1 has a Laufradsatzwelle 1 on. The wheelset shaft carries two wheels 2, 3, with which it is rotatably connected. It is a drive motor 4 is provided. Its axis of rotation 4.1 runs parallel to the axis of rotation 1.1 of the wheelset shaft.
Ein Getriebe 5 ist zwischen Antriebsmotor 4 und Laufradsatzwelle 1 geschaltet. Das Getriebe befindet sich im Zwischenraum zwischen einem der beiden Räder, nämlich dem Laufrad 2 und dem Motor 4. Es weist ein Zahnrad 5.1 auf. Das Zahnrad ist auf die Laufradsatzwelle 1 aufgekeilt. Es weist ferner ein Ritzel 5.2 auf. Das Ritzel 5.2 ist auf die Motorwelle aufgekeilt. Zahnrad 5.1 und Ritzel 5.2 sind von einem Getriebegehäuse 5.3 umschlossen.A transmission 5 is connected between the drive motor 4 and the wheelset shaft 1. The transmission is located in the space between one of the two wheels, namely the impeller 2 and the motor 4. It has a gear 5.1. The gear is keyed onto the wheelset shaft 1. It also has a pinion 5.2. The pinion 5.2 is keyed onto the motor shaft. Gear 5.1 and pinion 5.2 are enclosed by a gear housing 5.3.
Der Antriebsmotor 4 stützt sich auf einem Tragrohr 6 ab. Dieses ist auf der Laufradsatzwelle 1 gelagert. Das über den Antriebsmotor 4 eingeleitete Drehmoment wird über hier nicht gezeigte Drehmomentstützen abgestützt. Die Drehmomentstützen greifen einerseits am Antriebsmotor 4, und andererseits am Drehgestell des Achsantriebes an.The drive motor 4 is supported on a support tube 6. This is mounted on the wheelset shaft 1. The introduced via the drive motor 4 torque is supported by torque arms, not shown here. The torque arms engage on the one hand on the drive motor 4, and on the other hand on the bogie of the final drive.
Besteht die Notwendigkeit, die Triebverbindung zwischen dem Antriebsmotor 4 und der Laufradsatzwelle 1 zu unterbrechen, so müssen zunächst das Getriebegehäuse 5 vollständig demontiert, und sodann der Antriebsmotor 4 vom Tragrohr 6 getrennt werden. Dies ist außerordentlich aufwendig. Besteht die Notwendigkeit, wenn sich das Fahrzeug auf der Strecke befindet, beispielsweise durch Blockieren des Rotors des Antriebsmotors 4, so bleibt nichts anderes übrig, als das Fahrzeug abzuschleppen.If there is a need to interrupt the drive connection between the drive motor 4 and the wheel set shaft 1, first the gear housing 5 must be completely dismantled and then the drive motor 4 separated from the support tube 6. This is extremely expensive. Is there a need when the vehicle is on the track, for example by blocking the rotor of the drive motor 4, so there is nothing left but to tow the vehicle.
Die erfindungsgemäße Lösung ist in den Figuren 3 und 4 dargestellt. Gleiche Bauteile sind mit denselben Bezugszeichen versehen, wie in den Figuren 1 und 2. Die erfindungsgemäße Lösung weist gegenüber der konventionellen Bauart die folgenden Merkmale auf:The solution according to the invention is shown in FIGS. 3 and 4. Identical components are provided with the same reference numerals as in FIGS. 1 and 2. The solution according to the invention has the following features over the conventional design:
Das Getriebegehäuse 5 ist auf seiner dem Laufrad 2 zugewandten Seite offenbar. Es kann zu diesem Zwecke beispielsweise einen Deckel 5.4 aufweisen. Das Ritzel 5.2 lässt sich nach Abnehmen des Deckels 5.4 von der Welle des Antriebsmotors abziehen. Es wird dabei in den Zwischenraum zwischen dem Getriebe 5 und dem diesem benachbarten Laufrad 2 überführt, somit in einer Richtung parallel zur Drehachse der Laufradsatzwelle 1. Der Zwischenraum zwischen der Stirnseite des Ritzels 5.2 und der diesem zugewandten Seitenfläche des Laufrades 2 muss natürlich entsprechend bemessen sein. Seine Weite muss mindestens gleich der Länge des Ritzels 5.2 sein, im Allgemeinen noch etwas größer.The gear housing 5 is on its side facing the impeller 2 apparently. It may for this purpose, for example, have a cover 5.4. The pinion 5.2 can be removed after removing the cover 5.4 from the shaft of the drive motor. It is thereby transferred into the intermediate space between the gear 5 and the adjacent impeller 2, thus in a direction parallel to the axis of rotation of the Laufradsatzwelle 1. The space between the end face of the pinion 5.2 and the side surface facing the impeller 2 must of course be sized accordingly , Its width must be at least equal to the length of the pinion 5.2, generally even slightly larger.
Befindet sich das Ritzel 5.2 im genannten Zwischenraum, so ist dieIf the pinion is 5.2 in said space, so is the
Triebverbindung zwischen Antriebsmotor 4 und Laufradsatzwelle 1 gelöst. Eine Blockade des Rotors des Antriebsmotors 4 ist damit unbeachtlich. Der schadhafte Achsantrieb hindert das Schienenfahrzeug, somit im Allgemeinen die Lok, nicht mehr am Weiterfahren, angetrieben von anderen Einzel-Achsantrieben, die das Fahrzeug im Allgemeinen besitzt. Das Antriebsritzel 5 braucht dann nur noch in dem Zwischenraum auf irgendeine Weise gehalten zu werden.Drive connection between the drive motor 4 and wheelset shaft 1 solved. A blockage of the rotor of the drive motor 4 is thus irrelevant. The faulty final drive prevents the rail vehicle, thus generally the locomotive, from moving on, driven by other single axle drives that the vehicle generally possesses. The drive pinion 5 then only needs to be held in the space in some way.
Es kann aber auch, so wie in Figur 4 veranschaulicht, die Möglichkeit geschaffen sein, das Ritzel 5.2 noch weiterhin zu bewegen, und zwar in Richtung senkrecht zur Drehachse 1.1 der Laufradsatzwelle 1. Diese Bewegung wird ausgeführt bis zu einer Position des Ritzels 5.2 über den Außenumfang des Laufrades 2 hinaus. In dieser Position lässt sich das Ritzel 5.2 aus dem übrigen Achsantrieb völlig entfernen.However, as illustrated in FIG. 4, it may also be possible to continue to move the pinion 5.2 in the direction perpendicular to the axis of rotation 1.1 of the wheel set shaft 1. This movement is carried out up to a position of the pinion 5.2 over the pinion shaft Outside circumference of the impeller 2 addition. In this position, the pinion 5.2 can be completely removed from the rest of the final drive.
Die übrigen Bauteile des Achsantriebes können montiert bleiben, so wie sie sind. Es bedarf somit nicht mehr eines Lösens des Antriebsmotors 4 vom Tragrohr 6, oder des übrigen Getriebes vom Antriebsmotor 4 und vom hier nicht dargestellten Drehgestell.The remaining components of the final drive can remain mounted as they are. It thus no longer requires a release of the drive motor 4 from the support tube 6, or the rest of the transmission from the drive motor 4 and the bogie not shown here.
Beiden Rädern 2, 3 sind Bremseinrichtungen 7, 8 zugeordnet, was nur der Vollständigkeit wegen hier angedeutet ist.Both wheels 2, 3 are associated with brake devices 7, 8, which is indicated here only for the sake of completeness.
Aus der vergrößerten Darstellung von Figur 5 ist eine Einrichtung erkennbar, mit welcher das Ritzel 5.2 von der Welle des Antriebsmotors 4 abziehbar ist. Um ein Abziehen ohne Beschädigungen der beteiligten Bauteile durchzuführen, wird eine Distanzhülse 9 verwendet. Diese ist derart bemessen, dass einerseits ein komplettes Lösen des Ritzels 5.2 durch dessen Verschiebung in axialer Richtung erfolgen kann, und das andererseits der Verschiebeweg begrenzt ist durch ein Abstützen an der betreffenden Seite des Laufrades 2. Diese Begrenzung dient der Sicherheit. Dabei wird mittels einer Winkelverschraubung ein Druck zum Lösen des Pressverbandes durch Hydrauliköl aufgebracht.From the enlarged view of Figure 5, a device can be seen, with which the pinion 5.2 is deducted from the shaft of the drive motor 4. To perform a peeling without damaging the components involved, a spacer sleeve 9 is used. This is dimensioned such that on the one hand, a complete release of the pinion 5.2 can be done by its displacement in the axial direction, and on the other hand, the displacement is limited by a support on the respective side of the impeller 2. This limitation is for safety. In this case, a pressure for releasing the interference fit by hydraulic oil is applied by means of an angle fitting.
Das Getriebegehäuse 5 kann den umschlossenen Raum hermetisch absperren. Das Gehäuse 5 kann jedoch auch derart gestaltet sein, dass es lediglich dem Schutz von Zahnrad 5.1 und Ritzel 5.2 sowie der Aufnahme des Schmierstoffes für diese beiden Räder dient, da die Kräfteüberlagerungen im Tragrohr 6 und im Antriebsmotor 4 aufgenommen werden.The transmission housing 5 can hermetically seal the enclosed space. However, the housing 5 may also be designed so that it serves only the protection of gear 5.1 and pinion 5.2 and the inclusion of the lubricant for these two wheels, since the forces superimpositions are received in the support tube 6 and in the drive motor 4.
An der Radsatzwelle können Entlüfter und berührungslose Dichtungen vorgesehen werden, über die ein Druckausgleich zwischen dem Innenraum des Getriebegehäuses und der äußeren Umgebung erfolgt.At the wheelset bleeder and non-contact seals can be provided, via which a pressure equalization between the interior of the transmission housing and the external environment takes place.
Sind im Gehäuse Getriebelagerungen angeordnet, so muss das Getriebegehäuse auch Kräfte aufnehmen. Sind im Getriebegehäuse aber keine Getriebelagerungen angeordnet, so wie im dargestellten Fall, so dient das Gehäuse nur dem Schutz und der Ölversorgung. BezugszeichenlisteIf gearbox bearings are arranged in the housing, then the gearbox housing must also absorb forces. Are in the gearbox but no gearbox bearings arranged, as in the case shown, the housing is only the protection and the oil supply. LIST OF REFERENCE NUMBERS
