Description

Die Erfindung bezieht sich auf ein Triebaggregat für die Treibachsen von Schienenfahrzeugen mit einem in Längsrichtung des Schienenfahrzeugs 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 und in einem Gehäuseteil Aussparungen für den Durchtritt der Treibachse vorgesehen sind, wobei als gemeinsames Gehäuse aller Antriebsteile ein Hohlträger verwendet ist, der geeignete Montageschnittstellen zum Einsetzen der Antriebsteile aufweist und in dessen Wand durch Rippen oder Aussparungen gebildete Kühlkanäle vorgesehen sind. Ein derartiges Triebaggregat hat den Vorteil, daß der Hohlträger, dessen Länge der Triebaggregatslänge entspricht, ein Bauelement mit hohem Widerstandsmoment und entsprechend hoher Biege- und Drehsteifigkeit bildet, in dem alle Elemente des Triebaggregates untergebracht sind. Außerdem wird der Hohlträger zur Abführung der Wärmeverluste innerhalb des Triebaggregates ausgenutzt, da in seinen Wänden Kühlkanäle vorgesehen sind. Ein derartiges Triebaggregat ist in der nicht vorveröffentlichten EP-A-0 046 135 (Veröffentlichungstag 17.2.82) beschrieben.The invention relates to a drive unit for the driving axles of rail vehicles with an electric traction motor arranged in the longitudinal direction of the rail vehicle, the torque of which is transmitted to the driving axis via gears and couplings and in which the housing of the traction motor, the bearing and the gearbox accommodating one another connected and recesses are provided in a housing part for the passage of the drive shaft, a hollow support being used as the common housing of all drive parts, which has suitable mounting interfaces for inserting the drive parts and cooling channels formed by ribs or recesses are provided in the wall thereof. Such a drive unit has the advantage that the hollow beam, the length of which corresponds to the length of the drive unit, forms a component with a high section modulus and correspondingly high bending and torsional rigidity, in which all elements of the drive unit are accommodated. In addition, the hollow beam is used to dissipate the heat losses within the drive unit, since cooling channels are provided in its walls. Such a drive unit is described in the unpublished EP-A-0 046 135 (publication date February 17, 1982).

Der Erfindung liegt die Aufgabe zugrunde, mit einfachsten Mitteln bei einem derartigen Triebaggregat eine ausreichende Kühlung aller Elemente und insbesondere des Fahrmotors zu erhalten.The invention has for its object to obtain sufficient cooling of all elements and in particular the drive motor with the simplest means in such a drive unit.

Zur Lösung dieser Aufgabe ist das Triebaggregat der eingangs beschriebenen Art gemäß der Erfindung so ausgebildet, daß an einer oder beiden Stirnseiten des Hohlträgers ein Fremdlüfter angeordnet ist, der die Endöffnungen der Kühlkanäle des Hohlträgers mit Kühlluft beaufschlagt. Der Fremdlüfter ist somit in den Hohlträger integriert, wofür nur eine geringfügige Verlängerung des Hohlträgers über den Bereich der Getriebe hinaus erforderlich ist. Der Hohlträger dient dabei neben seiner Eigenschaft als Träger der Kühlkanäle auch als Träger von Leitschirmen für die Kühlluft und unmittelbar, z. B. über Arme, oder mittelbar, z. B. über das Getriebe, als Träger für den Fremdlüfter mit seinem Antrieb. Die Leistung des Fremdlüfters kann somit ohne Schwierigkeit entsprechend dem Kühlluftbedarf des Triebaggregates ausgelegt werden. Die Ansaugwege für die Kühlluft sind kurz.To achieve this object, the drive unit of the type described at the outset is designed in accordance with the invention in such a way that an external fan is arranged on one or both end faces of the hollow carrier, which fan acts on the end openings of the cooling channels of the hollow carrier with cooling air. The external fan is thus integrated in the hollow beam, for which only a slight extension of the hollow beam beyond the area of the gearbox is required. In addition to its property as a carrier for the cooling channels, the hollow carrier also serves as a carrier for guide screens for the cooling air and directly, for. B. over arms, or indirectly, e.g. B. on the gearbox, as a carrier for the external fan with its drive. The power of the external fan can thus be designed without difficulty according to the cooling air requirement of the drive unit. The suction paths for the cooling air are short.

Im folgenden sei die Erfindung noch anhand des in den Fig. 1 und 2 der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Fig. 1 zeigt schematisch, teilweise geschnitten, eine Draufsicht auf ein gemäß der Erfindung ausgebildetes Triebaggregat für die Treibachsen von Schienenfahrzeugen. Fig. 2 zeigt, ebenfalls prinzipiell dargestellt, einen Schnitt durch den Hohlträger im Bereich des elektrischen Fahrmotors.The invention will be explained in more detail below with reference to the exemplary embodiment shown in FIGS. 1 and 2 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, also shown in principle, a section 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 jeweils über eine Längsverschiebungen zulassende. zentrierende Kupplung 5 mit der das nicht dargestellte Ritzel tragenden Ritzelwelle 6 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 in each case permitting a longitudinal displacement. centering clutch 5 connected to the pinion shaft 6 carrying the pinion, not shown.

Um dem Triebaggregat eine große Biege- und Drehsteifigkeit zu erteilen, sind alle Antriebsteile, wie der elektrische Fahrmotor 1, die Ritzelwelle 6 und ihre Lagerung, und das Winkelgetriebe 2 im Innern eines Hohlträgers 8 angeordnet. Dieser Hohlträger 8 weist über seiner gesamten Länge die gleichen Außenabmessungen auf. Er enthält außerdem Aussparungen für den Durchtritt der Treibachsen 3 und weist geeignete Montageschnittstellen auf, welche die Aussparungen für die Treibachsen 3 schneiden und den Einbau der einzelnen Elemente des Triebsaggregates ermöglichen.In order to give the drive unit great bending and torsional rigidity, all drive parts, such as the electric drive motor 1, the pinion shaft 6 and its mounting, and the angular gear 2 are arranged in the interior of a hollow support 8. This hollow beam 8 has the same outer dimensions over its entire length. It also contains cutouts for the passage of the drive axles 3 and has suitable assembly interfaces which cut the cutouts for the drive axles 3 and enable the installation of the individual elements of the drive unit.

Außerdem ist der Hohlträger 8 auf seiner Innenfläche mit Rippen 9 versehen, zwischen denen Kühlkanäle 10 gebildet sind. Diese sind im Bereich des elektrischen Fahrmotors 1 durch den Ständer 11 verschlossen und im Bereich der Winkelgetriebe 2 durch deren Hohlträgerteile. An einer oder beiden Stirnseiten ist der Hohlträger 8 über das Winkelgetriebe 2 hinausgehend verlängert und dort ist ein Fremdlüfter 12 angeordnet, der zusammen mit seinem Antriebsmotor von den Hohlträgerteilen des Winkelgetriebes 2 getragen wird und über dessen Lüfterflügel 13 die Endöffnungen 14 der Kühlkanäle 10 im Hohlträger 8 mit Kühlluft beaufschlagt werden. Der Fremdlüfter 12 kann sowohl als Axiallüfter als auch als Radiallüfter ausgebildet sein. Die Stirnseite des Hohlträgers 8 kann außerdem mit geeigneten Schirmen 15 zur Führung der Kühlluft und zur Bildung einer angemessenen Kühllufteintrittsöffnung 16 versehen sein. Auf diese Weise wird über den Fremdlüfter 12 die zur ausreichenden Kühlung sämtliche Elemente des Triebaggregates erforderliche Kühlluftmenge in das Innere des Hohlträgers 8 geleitet. Der Kühlluftaustritt kann bei einem nur an einer Stirnseite, wie dargestellt, angeordneten Fremdlüfter 12 an der gegenüberliegenden Stirnseite des Hohlträgers 8 erfolgen. Es ist aber auch möglich, Kühlluftaustrittsöffnungen in Hohlträgermitte vorzusehen, wenn an jeder Stirnseite ein Fremdlüfter angeordnet ist, was vorteilhaft ist, wenn der Fahrmotor 1 als Doppelmotor mit entkoppelten Läuferwellen 4 ausgebildet ist.In addition, the hollow support 8 is provided on its inner surface with ribs 9, between which cooling channels 10 are formed. These are closed in the area of the electric traction motor 1 by the stand 11 and in the area of the angular gear 2 by their hollow support parts. On one or both end faces, the hollow beam 8 is extended beyond the angular gear 2 and there is an external fan 12 which is carried together with its drive motor by the hollow beam parts of the angular gear 2 and via its fan blades 13 the end openings 14 of the cooling channels 10 in the hollow beam 8 be supplied with cooling air. The external fan 12 can be designed both as an axial fan and as a radial fan. The end face of the hollow support 8 can also be provided with suitable screens 15 for guiding the cooling air and for forming an appropriate cooling air inlet opening 16. In this way, the amount of cooling air required for sufficient cooling of all elements of the drive unit is conducted into the interior of the hollow support 8 via the external fan 12. The cooling air outlet can take place in the case of an external fan 12 arranged only on one end face, as shown, on the opposite end face of the hollow support 8. However, it is also possible to provide cooling air outlet openings in the center of the hollow support if an external fan is arranged on each end face, which is advantageous if the traction motor 1 is designed as a double motor with decoupled rotor shafts 4.

Durch die Anordnung sämtlicher Antriebsteile im Innern des Hohlträgers 8, die auch den für eine ausreichende Kühlluftzuführung erforderlichen Fremdlüfter 12 enthalten, wird ein sehr steifes, im Hinblick auf Lauf- und Betriebseigenschaften güntiges Gebilde geschaffen. Dadurch kann der Hohlträger 8 auch die Funktion des Längsmittenträgers des Drehgestells 17 übernehmen und ist somit mit seitlichen Armen 18 versehen, welche die Radsatztragarme. des Drehgestells 17 bilden.The arrangement of all drive parts in the interior of the hollow support 8, which also contain the external fan 12 required for a sufficient supply of cooling air, creates a very rigid structure which is favorable in terms of running and operating properties. As a result, the hollow beam 8 can also take over the function of the longitudinal center beam of the bogie 17 and is thus provided with side arms 18 which hold the wheelset support arms. form the bogie 17.
