Abstract

In a propulsion unit for the driven axles of an electrically-powered rail vehicle, the torque of an electric propulsion motor is transmitted to the respective driven axle by way of a torque transmitting mechanism including gears and couplings. A common housing in the form of a hollow beam is used to enclose the propulsion motor, a bearing system, and a transmission. Cut-outs are provided in the sides of the housing to allow space for the driven axles. In order to increase the flexural and torsional stiffness of the propulsion unit, the hollow beam includes an annular end surface through which the propulsion motor and torque transmitting apparatus are inserted. The hollow beam not only forms a common housing or the propulsion components, but is a very stiff support element that reduces vibration and improves the running behavior of the propulsion unit.

Description

Die Erfindung bezieht sich auf ein Triebaggregat für die Treibachsen von Schienenfahrzeugen mit einem in Längsrichtung angeordneten elektrischen Fahrmotor, dessen Drehmoment über Getriebe und Kupplungen auf die Treibachse übertragen wird und bei dem die den Ständer des Fahrmotors, die Lagerung und das Getriebe aufnehmenden Gehäuse miteinander verbunden sind, wobei in Gehäuseteilen Aussparungen für den Durchtritt der Treibachse vorgesehen sind. Ein derartiges Triebaggregat ist aus der DE-B 2325787 und DE-B 2364594 bekannt. Die konstruktive Ausbildung der miteinander verbundenen Gehäuse ist jeweils hinsichtlich der äusseren Abmessungen entsprechend den in ihnen enthaltenen Antriebsteilen gestaltet. Die erforderlichen Randbedingungen, wie Ritzelwellenlagerung und Anordnung des Drehgestellquerträgers, ergeben aufgrund des nur beschränkt zur Verfügung stehenden Raumes Einschnürungen, die sich nachteilig auf die Stabilität des Triebaggregates auswirken.The invention relates to a drive unit for the drive axles of rail vehicles with a longitudinally arranged electric drive motor, the torque of which is transmitted to the drive axle via gears and clutches and in which the housing of the drive motor, the bearing and the gearbox are connected to one another , with recesses being provided in the housing parts for the passage of the drive axle. Such a drive unit is known from DE-B 2325787 and DE-B 2364594. The structural design of the interconnected housings is designed with respect to the outer dimensions in accordance with the drive parts contained in them. The required boundary conditions, such as pinion shaft mounting and arrangement of the bogie cross member, result in constrictions due to the limited space available, which have a disadvantageous effect on the stability of the drive unit.

Weiterhin ist aus der FR-A 2329492 ein integrierter Antrieb eines elektrischen Schienenfahrzeuges bekannt, bei dem der elektrische Motor kein eigenes Gehäuse hat. Der Ständer besteht aus einem Ständerblechpaket und Druckplatten, die durch Zugelemente zusammengehalten werden. Man hat es also bereits beim Ständer des elektrischen Fahrmotors nicht mit einem einteiligen Bauteil zu tun. Im übrigen sind die Getriebegehäuse, die auf jeder Seite wieder unabhängige eigene Bauteile darstellen, an den Druckplatten des Fahrmotors befestigt, d.h. an dieser Stelle müssen die zu übertragenden Kräfte und Beanspruchungen von den Befestigungsmitteln aufgenommen werden. Ausserdem tragen die Getriebegehäuse die Lagerung für die Läuferwelle. Es handelt sich bei der bekannten Anordnung mithin um den Antrieb eines elektrischen Schienenfahrzeuges, bei dem die Getriebegehäuse tragende Funktionen für den Fahrmotor übernommen haben, der gehäuselos ist, diese Teile aber untereinander wie üblich miteinander verbunden sind.Furthermore, an integrated drive of an electric rail vehicle is known from FR-A 2329492, in which the electric motor does not have its own housing. The stand consists of a stator core and pressure plates that are held together by tension elements. So it is not already a one-piece component when it comes to the stator of the electric traction motor. For the rest, the gearbox housings, which are independent components on each side, are attached to the pressure plates of the traction motor, i.e. At this point, the forces and stresses to be transmitted must be absorbed by the fasteners. In addition, the gearbox housing supports the rotor shaft. It is therefore in the known arrangement to drive an electric rail vehicle, in which the transmission housing have taken over supporting functions for the traction motor, which is housingless, but these parts are interconnected as usual.

Der Erfindung liegt die Aufgabe zugrunde, die Biege- und Drehsteifigkeit eines Triebaggregates für Schienenfahrzeuge zu erhöhen. Zur Lösung dieser Aufgabe ist ein Triebaggregat der eingangs beschriebenen Art gemäss der Erfindung so ausgebildet, dass als gemeinsames Gehäuse aller Antriebsteile ein zwischen den Triebachsen im tragenden Bereich als einteiliges Bauteil ausgebildeter Hohlträger verwendet ist, der geeignete Montageschnittstellen zum Einsetzen der Antriebsteile aufweist. Ein derartiger Hohlträger, dessen Länge der Triebaggregatslänge entspricht, hat ein hohes Widerstandsmoment und entsprechend eine hohe Biege- und Drehsteifigkeit. Trotz der für einige Antriebsteile gegenüber dem bisher Üblichen vergrösserten Aussenabmessungen dieses gemeinsamen Gehäuses wird insgesamt ohne Beeinträchtigung des Drehmomenterzeugungs- und Übertragungssystems infolge der wesentlichen Erhöhung der Biegesteifigkeit eine Gewichtsersparnis erzielt. Ausserdem ergibt sich ein günstiges Schwingungs- und Laufverhalten.The invention has for its object to increase the bending and torsional rigidity of a drive unit for rail vehicles. To solve this problem, a drive unit of the type described at the outset is designed in accordance with the invention in such a way that a hollow support formed as a one-piece component between the drive axles in the supporting area is used as a common housing for all drive parts and has suitable mounting interfaces for inserting the drive parts. Such a hollow beam, the length of which corresponds to the length of the drive unit, has a high section modulus and, accordingly, high bending and torsional rigidity. In spite of the fact that the external dimensions of this common housing have been enlarged for some drive parts compared to what has been usual up to now, a weight saving is achieved overall without impairing the torque generation and transmission system as a result of the substantial increase in the bending stiffness. In addition, there is a favorable vibration and running behavior.

Der Einbau der Antriebsteile in das durch den Hohlträger gebildete gemeinsame Gehäuse bereitet keine Schwierigkeiten, da der Hohlträger geeignete Montageschnittstellen aufweist. Diese können den Hohlträger horizontal oder vertikal teilend oder auch die Aussparungen für die Treibachsen schneidend verlaufen.The installation of the drive parts in the common housing formed by the hollow support presents no difficulties, since the hollow support has suitable assembly interfaces. These can divide the hollow beam horizontally or vertically or cut the recesses for the drive axles.

Für den Hohlträger, der mit Vorteil über seiner gesamten Länge die gleichen Aussenabmessungen aufweist, kann ein beliebiges geeignetes Material ausreichender Festigkeit gewählt werden, z.B. Aluminiumlegierungen. Es empfiehlt sich aber auch die Verwendung von ferromagnetischem Material derart, dass der Hohlträger im Bereich des Fahrmotors ganz oder teilweise dessen magnetischen Ständerkreis bildet. Dadurch wird auch die Funktion des magnetischen Kreises im Fahrmotorbereich von dem Hohlträger mit übernommen.Any suitable material of sufficient strength can be selected for the hollow beam, which advantageously has the same external dimensions over its entire length, e.g. Aluminum alloys. However, it is also advisable to use ferromagnetic material in such a way that the hollow support in the area of the traction motor forms all or part of its magnetic stator circuit. As a result, the function of the magnetic circuit in the traction motor area is also taken over by the hollow beam.

Es ist weiterhin vorteilhaft, die Wand des Hohlträgers mit Rippen bzw. Aussparungen zu versehen, damit der Hohlträger zur Abführung der Wärmeverluste innerhalb des Triebaggregates ausgenutzt werden kann.It is also advantageous to provide the wall of the hollow beam with ribs or cutouts so that the hollow beam can be used to dissipate the heat losses within the drive unit.

Es empfiehlt sich ferner, den Hohlträger in das Drehgestell zu integrieren, in dem er als Längsmittenträger des Drehgestells ausgebildet ist und seitliche Arme aufweist, welchen die Radsatztragarme bilden. Dies ist wegen der gegebenen grossen Biege- und Drehsteifigkeit des Hohlträgers möglich, so dass eine wesentliche Vereinfachung des Drehgestellaufbaus erreicht wird, weil der bisher übliche Drehgestellrahmen entfällt, da seine Funktion durch den Hohlträger übernommen wird.It is also recommended to integrate the hollow beam in the bogie, in which it is designed as a longitudinal center beam of the bogie and has side arms, which form the wheelset support arms. This is possible because of the given great bending and torsional rigidity of the hollow beam, so that a significant simplification of the bogie structure is achieved because the previously common bogie frame is omitted because its function is taken over by the hollow beam.

Im folgenden ist die Erfindung noch anhand der in den Fig. 1 bis 5 der Zeichnung dargestellten Ausführungsbeispiele näher erläutert. Fig. 1 zeigt schematisch, teilweise geschnitten, eine Draufsicht auf ein gemäss der Erfindung ausgebildetes Triebaggregat für die Treibachsen von Schienenfahrzeugen. In Fig. 2 ist eine Seitenansicht, teilweise nach Linie 11-11 in Fig. 1 geschnitten, dargestellt. Die Fig. 3 bis 5 zeigen, ebenfalls prinzipiell dargestellt, Schnitte durch den Hohlträger im Bereich des elektrischen Fahrmotors.The invention is explained in more detail below with reference to the exemplary embodiments illustrated in FIGS. 1 to 5 of the drawing. Fig. 1 shows schematically, partially in section, a plan view of a drive unit designed according to the invention for the drive axles of rail vehicles. FIG. 2 shows a side view, partly cut along line 11-11 in FIG. 1. 3 to 5 show, also shown in principle, sections through the hollow beam in the area of the electric traction motor.

Bei dem in den Fig. 1 und 2 dargestellten Schienenfahrzeug treibt der elektrische Fahrmotor 1 jeweils über Winkelgetriebe 2 zwei Treibachsen 3 an. Der elektrische Fahrmotor 1 liegt senkrecht zu den beiden Treibachsen 3 und seine Läuferwelle 4 ist beidseitig über eine Längsverschiebungen zulassende, zentrierende Kupplung 5 mit der das Ritzel 6 tragenden Ritzelwelle 7 verbunden. Das Ritzel 6 steht im Eingriff mit dem Grossrad 8 des Winkelgetriebes 2, welches auf der die Treibachse 3 mit Spiel umgebenden Hohlwelle 9 angeordnet ist. Die Hohlwelle 9 ist ihrerseits über eine elastische und zentrierende Gummikupplung 10 mit der Treibachse 3 verbunden.In the rail vehicle shown in FIGS. 1 and 2, the electric traction motor 1 drives two drive axles 3 each via angular gears 2. The electric traction motor 1 is perpendicular to the two drive axles 3 and its rotor shaft 4 is connected on both sides to the pinion shaft 7 carrying the pinion 6 via a centering coupling 5 which allows longitudinal displacements. The pinion 6 is in engagement with the large wheel 8 of the angular gear 2, which is arranged on the hollow shaft 9 surrounding the drive shaft 3 with play. The hollow shaft 9 is in turn connected to the drive shaft 3 via an elastic and centering rubber coupling 10.

Um dem Triebaggregat eine grosse Biege- und Drehsteifigkeit zu erteilen, sind alle Antriebsteile, wie der elektrische Fahrmotor 1, die Ritzelwelle 7 und ihre Lagerung, gebildet durch Wälzlager 11 und das Winkelgetriebe 2 im Innern eines Hohlträgers 12 angeordnet. Dieser Hohlträger 12 weist über seiner gesamten Länge die gleichen Aussenabmessungen auf. Er enthält ausserdem Aussparungen 13 für den Durchtritt der Treibachsen 3 und der sie umgebenden Hohlwelle 9 und ist an den Stirnseiten durch Stirnwände 14 abgeschlossen. Um das Einsetzen der Antriebsteile zu ermöglichen, weist der Hohlträger 12 weiterhin Montageschnittstellen 15 auf, die schräg, die Aussparungen 13 für die Treibachse 3 schneidend, verlaufen.In order to give the drive unit great bending and torsional rigidity, all drive parts, such as the electric traction motor 1, the pinion shaft 7 and their bearings, formed by roller bearings 11 and the angular gear 2, are arranged inside a hollow support 12. This hollow beam 12 has the same outer dimensions over its entire length. It also contains cutouts 13 for the passage of the driving axles 3 and the hollow shaft 9 surrounding them and is closed off at the end faces by end walls 14. In order to make it possible to insert the drive parts, the hollow support 12 also has mounting interfaces 15 which run obliquely, cutting the cutouts 13 for the drive shaft 3.

Zur Montage des Triebaggregates wird zunächst der elektrische Fahrmotor 1, der komplett mit Gehäuse, Lagerschilden und Lagerung für die Läuferwelle 4 ausgebildet ist, in das Innere des Hohlträgers 12 hineingeschoben, wobei seine Lage in Längsrichtung durch einen Anschlag 16 im Innern des Hohlträgers 12 festgelegt ist auf der anderen Stirnseite des Fahrmotors 1 wird dann ein Abstandsring 17 eingeführt und darauf wird das Traggehäuse 18 für die Wälzlager 11 der Ritzelwelle 7 eingeschoben. Weiterhin ist über Wälzlager 19 die Hohlwelle 9 im Hohlträger 12 gelagert, so dass der Hohlträger 12 dort das Gehäuse für das Winkelgetriebe 2 bildet. Es sind entsprechende Dichtungen vorgesehen, durch welche innerhalb des Hohlträgers 12 die Bereiche für das Umlaufen der für das Winkelgetriebe 2 bzw. für die verschiedenen Lagerungen erforderlichen Schmiermittel begrenzt werden.To assemble the drive unit, the electric traction motor 1, which is completely designed with a housing, end shields and bearings for the rotor shaft 4, is first pushed into the interior of the hollow support 12, its position in the longitudinal direction being determined by a stop 16 inside the hollow support 12 A spacer ring 17 is then introduced on the other end face of the traction motor 1 and the support housing 18 for the roller bearings 11 of the pinion shaft 7 is inserted thereon. Furthermore, the hollow shaft 9 is supported in the hollow support 12 via roller bearings 19, so that the hollow support 12 forms the housing for the angular gear 2 there. Corresponding seals are provided, by means of which the areas for the circulation of the lubricants required for the angular gear 2 or for the various bearings are limited within the hollow support 12.

Durch diese Anordnung sämtlicher Antriebsteile im Innern des Hohlträgers 12 wird ein sehr steifes, im Hinblick auf Lauf- und Betriebseigenschaften günstiges Gebilde geschaffen. Ausserdem übernimmt dieser Hohlträger 12 die Funktion des Längsmittenträgers des Drehgestells 20 und ist deshalb mit seitlichen Armen 21 versehen, welche die Radsatztragarme des Drehgestells 20 bilden. Durch diesen Einsatz eines sehr steifen, sich über die gesamte Länge des Triebaggregates erstreckenden Hohlträgers wird sowohl für das Triebaggregat als auch für das Drehgestell 20 Platz und Gewicht gespart.This arrangement of all drive parts in the interior of the hollow support 12 creates a very rigid structure which is favorable in terms of running and operating properties. In addition, this hollow beam 12 takes over the function of the longitudinal center beam of the bogie 20 and is therefore provided with side arms 21 which form the wheelset support arms of the bogie 20. This use of a very rigid hollow beam, which extends over the entire length of the drive unit, saves space and weight for both the drive unit and the bogie.

Der Hohlträger 12 kann im Bereich des elektrischen Fahrmotors 1, sofern er aus ferromagnetischem Material besteht, nicht nur mechanisch tragende Funktionen übernehmen, sondern auch ganz oder teilweise dessen magnetischen Ständerkreis 22 bilden. Fig. 3 zeigt eine Ausführung, bei welcher der Hohlträger 12 zur Führung eines Teils des magnetischen Flusses des Ständerkreises 22 ausgenutzt wird, so dass trotz Vorliegen eines geschlossenen Ständerjoches 23 das Haupt- 24 und Wendepole 25 trägt, dessen Höhe verringert ist.In the area of the electric traction motor 1, provided that it is made of ferromagnetic material, the hollow beam 12 can not only perform mechanically load-bearing functions, but can also wholly or partly form its magnetic stator circuit 22. Fig. 3 shows an embodiment in which the hollow support 12 is used to guide a part of the magnetic flux of the stator circuit 22, so that despite the presence of a closed stator yoke 23, the main 24 and reversing poles 25 carry, the height of which is reduced.

In Fig. 4 ist eine Ausführung dargestellt, bei welcher die geblechten Hauptpole 24 und Wendepole 25 mit ihren Erregerwicklungen 26 bzw. 27 unmittelbar in den Hohlträger 12 eingesetzt wird, so dass dieser hier den magnetischen Ständerkreis 22 allein bildet.4 shows an embodiment in which the laminated main poles 24 and reversing poles 25 with their excitation windings 26 and 27 are inserted directly into the hollow support 12, so that this forms the magnetic stator circuit 22 alone.

Man kann die Formgebung des Hohlträgers 12 auch so auswählen, dass er zur Abführung der innerhalb der Antriebsteile entstehenden Verluste mittels gasförmiger bzw. flüssiger Medien herangezogen werden kann. Dazu empfiehlt es sich, wie in Fig. 5 dargestellt, den Hohlträger 12 entweder mit Aussparungen 28 zu versehen, die Kühlkanäle für das zur Kühlung verwendete Medium bilden, oder mit Rippen 29 zur Vergrösserung der kühlenden Oberfläche.The shape of the hollow support 12 can also be selected such that it can be used to discharge the losses occurring within the drive parts by means of gaseous or liquid media. For this purpose, it is advisable, as shown in FIG. 5, to provide the hollow support 12 either with cutouts 28 which form cooling channels for the medium used for cooling, or with ribs 29 to enlarge the cooling surface.
