Description

Beschreibung description
Doppelachsantrieb Die Erfindung betrifft einen Doppelachsantrieb und ein Fahr¬ werk eines Schienenfahrwerks . The invention relates to a double-axle drive and a drive ¬ work of a rail chassis .
Bei Schienenfahrzeugen mit Längsantrieben, Mittenantrieben oder je einem außenliegenden Längsantrieb, also sogenannten Doppelachsantrieben, werden an einem Fahrmotor an seinen jeweiligen Enden seiner Rotorwelle ein Achsgetriebe montiert als Antrieb eines Rades oder Radsatzes, wodurch eine mehrtei¬ lige Gehäusekonstruktion entsteht. Das Gehäuse des Fahrmotors dieses Längsantriebs beinhaltet bisher lediglich ein Lagerschild, wobei die Getriebe jeweils ein eigenes Gehäuse mit Getriebedeckel aufweisen und somit die gesamte Konstruktion des Doppelachsantriebs aus mehreren Teilen, insbesondere Gehäuseteilen, besteht, wie dies bei- spielsweise der EP 0 718 170 AI zu entnehmen ist. In rail vehicles with longitudinal drives, center drives or one external longitudinal drive, so-called Doppelachsantrieben, a axle drive are mounted on a traction motor at its respective ends of its rotor shaft as drive a wheel or wheelset, whereby a mehrtei ¬ lige housing construction arises. The housing of the drive motor of this longitudinal drive so far only includes a bearing plate, wherein the gear each have their own housing with gear cover and thus the entire construction of Doppelachsantriebs consists of several parts, in particular housing parts, as for example, EP 0 718 170 AI can be found.
Ausgehend davon liegt der Erfindung die Aufgabe zugrunde, ei¬ nen derartigen Doppelachsantrieb bezüglich seines Aufbaus zu vereinfachen und ein dementsprechendes Fahrwerk für ein Based on this, the present invention seeks to simplify ei ¬ nen such a double-axle drive with respect to its structure and a corresponding chassis for a
Schienenfahrzeug zu schaffen. To create rail vehicle.
Die Lösung der gestellten Aufgabe gelingt durch einen Doppelachsantrieb zumindest mit einem zwischen zwei Treibachsen an¬ geordneten Fahrmotor, dessen Drehachse quer, insbesondere senkrecht zu den Treibachsen verläuft, wobei mittels einer Antriebswelle des Fahrmotors jeweils über ein Getriebe eine Radsatzwelle antreibbar ist, wobei der gesamte Doppelachsan¬ trieb in einer Gehäuseeinheit angeordnet ist, die zwei The solution of the problem is achieved by a Doppelachsantrieb with at least one between two drive axles ¬ ordered traction motor whose axis of rotation transversely, in particular perpendicular to the drive axles, by means of a drive shaft of the drive motor via a gear a wheelset is driven, the entire Doppelachsan ¬ drive is arranged in a housing unit, the two
Gehäuseabschnitte aufweist. Has housing sections.
Die Lösung der gestellten Aufgabe gelingt auch durch ein Fahrwerk eines Schienenfahrzeugs mit zumindest zwei paralle- len Doppelachsantrieben, die durch wenigstens einen Längsträger miteinander mechanisch verbunden sind. The solution of the problem is also achieved by a chassis of a rail vehicle with at least two parallel len Doppelachsantrieben, which are mechanically connected by at least one longitudinal beam.
Erfindungsgemäß ist nunmehr zwischen den beiden Treibachsen lediglich nur noch eine Gehäuseeinheit vorgesehen, die nunmehr Bestandteile des Fahrmotors, des Lagers, der Kupplung und zwei Getrieben beinhaltet, so dass die Herstell- und Mon¬ tagekosten und auch das Gewicht gegenüber herkömmlichen Doppelachsantrieben reduziert wird. According to the invention is now only just a housing unit provided between the two driving axles, which now includes components of the traction motor, of the bearing of the clutch and two gears, so that the manufacturing and assembly ¬ daily cost and also the weight over conventional Doppelachsantrieben is reduced.
Vorteilhafterweise ist dabei das Getriebe als Hypoidkegel- radgetriebe oder als normales Winkelgetriebe ausgeführt. Die¬ se kompakten Getriebe eignen sich insbesondere für derartige Doppelachsantriebe, da sich dort der Kraftfluss auf engstem Raum nahezu ideal umlenken lässt. Um nun die beiden Gehäuse¬ abschnitte kraftschlüssig miteinander zu verbinden, werden an den Stoßstellen Flanschflächen ausgeführt, an denen diese beiden Gehäuseabschnitte verbindbar sind. Advantageously, the gear is designed as Hypoidkegel- gear or normal angular gear. The ¬ se compact gearboxes are particularly suitable for such Doppelachsantriebe because there the power flow can be almost ideal redirect in a confined space. In order to connect the two housing ¬ sections frictionally with each other, flange surfaces are carried out at the joints where these two housing sections are connected.
Vorteilhafterweise verlaufen diese Flanschflächen senkrecht zur Antriebswelle des Rotors des Fahrmotors oder parallel zu den Treibachsen. Damit vereinfacht sich die Herstellung derartiger Flanschflächen. Advantageously, these flange surfaces are perpendicular to the drive shaft of the rotor of the drive motor or parallel to the drive axles. This simplifies the production of such flange surfaces.
Um dem Statorblechpaket des Fahrmotors einen durchgehenden Sitz im Gehäuse zu gewährleisten, werden die Flanschflächen außerhalb, insbesondere axial außerhalb des Statorblechpakets vorgesehen. Damit vereinfacht sich auch der Schrumpfsitz des Statorblechpakets innerhalb des dafür vorgesehenen Gehäuse¬ abschnitts. Die auf das Statorblechpaket wirkenden Drehmomen¬ te Im Betrieb des Doppelachsantriebs werden dadurch besser aufgenommen. Dabei bleibt auch die Demontierbarkeit der je¬ weiligen Gehäuseabschnitte erhalten. In order to ensure the stator laminated core of the traction motor a continuous seat in the housing, the flange surfaces are provided outside, in particular axially outside the stator lamination. This also the shrink fit of the stator lamination within the designated housing ¬ portion simplified. The forces acting on the stator lamination stack Drehmomen ¬ te In operation of the Doppelachsantriebs be characterized added better. In this case, the disassembly of the respective ¬ housing housing sections is retained.
