Description

  

  Kardanachsantrieb für elektrische Schienenfahrzeuge.    Bei Achsantrieben elektrischer Schienen  fahrzeuge mit in Quer- oder Geleisrichtung  liegenden Kardanwellen, welche entweder die  hohle Motorwelle durchdringen oder selbst  als Hohlwelle ausgebildet sind, besteht mei  stens der Nachteil, dass ein Kupplungsflansch  mit der hohlen Welle durch Konstruktions  elemente verbunden ist, die viel Platz bean  spruchen und nur schwer lösbar sind.  



  Der erfindungsgemässe Kardanachsantrieb  bezweckt, diese Nachteile zu beseitigen und  ist dadurch gekennzeichnet, dass an einem  Hohlwellenende sowie am Kupplungsflansch  Zacken vorgesehen sind, die ineinandergrei  fen, und dass die beiden Teile durch Schrau  ben     zusammengehalten    sind.  



  Die beiliegende Zeichnung stellt zwei bei  spielsweise Ausführungsformen des     Erfin-          dungsgegenstandes    dar.  



  Fig. 1 bis 3 zeigen in Stirnansicht, Seiten  ansicht und im Schnitt Einzelheiten, und  Fig. 4 und 5 zeigen je eine Ausführungs  form.  



  Der dargestellte Kardanachsantrieb weist  eine Hohlwelle 1 auf, die mit einem ein Kar  dangelenk 3 tragenden Kupplungsflansch 2  verbunden     ist.     



  Fig. 1 zeigt das Hohlwellenende, an wel  chem Zacken 4 vorgesehen sind, die in der.  Achsrichtung vorspringen. Diese Zacken 4  greifen in am Kupplungsflansch 2 ausgebil  dete ähnliche Zacken 4' ein (Fig. 2). Es sind  zwei Gruppen von parallelen Zacken vorgese-    hen, wobei die Zacken in der einen Gruppe in  ihrer Längsrichtung senkrecht zu den Zacken  in der andern Gruppe verlaufen.  



  Statt gruppenweise parallel zu sein, könn  ten die Zacken ebenfalls radial angeordnet  sein.  



  Die beiden Teile 1 und 2 sind durch,  Schrauben 5 zusammengehalten, so dass eine  feste, leicht lösbare Verbindung gebildet ist.  Diese Schrauben dienen lediglich für die Zu  sammenhaltung der beiden. erwähnten Teile in  der Axialrichtung und werden praktisch nicht  auf Schub beansprucht.  



  Wie aus Fig. 4 ersichtlich ist, ist die Hohl  welle 1 als Antriebswelle des Motors 6 aus  gebildet, welcher im Fahrgestellrahmen be  festigt ist. Durch diese Hohlwelle geht die ;  Kardanwelle 7 hindurch, die an jedem Ende  ein Kardangelenk 3 bzw. 3' aufweist. Die lös  bare Verbindung zwischen Hohlwelle und  Kupplungsflansch befindet sich bei B.  



  In der Variante nach     Fig.    5 ist die Kar  danwelle selbst als Hohlwelle 1 ausgebildet,  die von der Radachse 9 durchdrungen ist.  8 bezeichnet     ebenfalls    die beschriebene lösbare  Verbindung zwischen Hohlwelle und Kupp  lungsflansch.



  Cardan axle drive for electric rail vehicles. In the case of axle drives of electric rail vehicles with cardan shafts lying in the transverse or track direction, which either penetrate the hollow motor shaft or are themselves designed as a hollow shaft, there is usually the disadvantage that a coupling flange is connected to the hollow shaft by construction elements that require a lot of space say and are difficult to solve.



  The purpose of the cardan axle drive according to the invention is to eliminate these disadvantages and is characterized in that prongs are provided on a hollow shaft end and on the coupling flange, which mesh with one another, and that the two parts are held together by screws.



  The accompanying drawing shows two exemplary embodiments of the subject matter of the invention.



  Fig. 1 to 3 show in front view, side view and in section details, and Fig. 4 and 5 each show an embodiment.



  The cardan axle drive shown has a hollow shaft 1 which is connected to a coupling flange 2 carrying a Kar dangelenk 3.



  Fig. 1 shows the hollow shaft end, on wel chem prongs 4 are provided in the. Axial direction protrude. These prongs 4 engage in ausgebil Dete similar prongs 4 'on the coupling flange 2 (Fig. 2). Two groups of parallel prongs are provided, the prongs in one group running in their longitudinal direction perpendicular to the prongs in the other group.



  Instead of being parallel in groups, the prongs could also be arranged radially.



  The two parts 1 and 2 are held together by screws 5, so that a firm, easily detachable connection is formed. These screws are only used to hold the two together. mentioned parts in the axial direction and are practically not subjected to thrust.



  As can be seen from Fig. 4, the hollow shaft 1 is formed as a drive shaft of the motor 6, which is fastened in the chassis frame BE. Through this hollow shaft goes the; Cardan shaft 7 through, which has a cardan joint 3 or 3 'at each end. The releasable connection between the hollow shaft and the coupling flange is at B.



  In the variant according to FIG. 5, the Kar danwelle itself is designed as a hollow shaft 1 which is penetrated by the wheel axle 9. 8 also denotes the releasable connection described between the hollow shaft and the coupling flange.
