Description

  

  Triebfahrgestell, insbesondere für Trolleybusse und ähnliche Fahrzeuge.    Die Erfindung bezieht sich auf Triebfahr  gestelle, insbesondere für Trolleybusse und  ähnliche Fahrzeuge mit Rädern, die unab  hängig     voneinander    abgefedert und je mit  einem besonderen Antriebsmotor versehen  sind. Bei den bekannten Fahrgestellen die  ser Art sind die Antriebsmotoren in der Nähe  des     innern    Endes der sich annähernd über die  halbe Fahrgestellbreite erstreckenden Halb  achsen der Räder angeordnet.

   Da die Aus  masse der Antriebsmotoren insbesondere für  schwere Autobusse ziemlich beträchtlich sind,  so erfordert die angegebene Anordnung der  Motoren gerade in der Fahrgestellmitte viel  Raum und bedingt somit einen hochliegen  den Wagenkastenboden, also hochliegenden  Wagenkasten und     Gesamtschwerpunkt.    Nun  ist aber gerade bei Trolleybussen und ähn  lichen Fahrzeugen eine möglichst tiefe  Lage des Wagenbodens, besonders in der  Wagenmitte, wo sich der Laufgang zwi  schen den Sitzen befindet, äusserst wün  schenswert.    Eine tiefe Anordnung des Wagenkasten  bodens wird gemäss der Erfindung dadurch  ermöglicht, dass die Motoren seitlich entfernt  von der Fahrgestellmitte angeordnet sind.  



  Zweckmässig sind die     Antriebsmotoren     der Räder und die zugehörigen Räder je  weils auf verschiedenen Seiten der Fahr  gestellmitte angeordnet und die Räder auf  Pendelachsen gelagert, die länger sind als  die halbe Fahrgestellbreite, wobei jeder An  triebsmotor auf der Pendelachse des zuge  hörigen Rades zwischen diesem Rad und  dem vom Rad aus jenseits der Fahrgestell  mitte liegenden Anlenkungspunkt der Pen  delachse vorzugsweise in unmittelbarer Nähe  desselben angeordnet ist.  



  Es können die Motoren aber auch auf  der den zugehörigen Rädern abgewendeten  Seite der Fahrgestellmitte, jedoch so ange  ordnet sein, dass die Anlenkungspunkte der  Pendelachsen sich zwischen den Motoren und  den von ihnen angetriebenen Rädern befin  den, so dass die beiderseits des Anlenkungs-      Punktes angreifenden Gewichte der Pendel  achse sich wenigstens teilweise im Gleich  gewicht halten.  



  In der Zeichnung sind beispielsweise Aus  führungsformen des Erfindungsgegenstandes  veranschaulicht, und zwar zeigt  Fig. 1 eine Ausführungsform im Grund  riss, teilweise im Schnitt,  Fig. 2 diese Ausführungsform in     End-          ansicht    und  Fig. 3 eine etwas abgeänderte Ausfüh  rungsform mit unterhalb der Radlagerzapfen  endenden Antriebswellen.  



  Jedes der Räder 1 des Fahrgestelles steht  durch ein Stirnradgetriebe 2, 3, eine An  triebswelle 4 und gegebenenfalls durch ein  zweites Stirnradgetriebe 5, 6 in Verbindung  mit einem Elektromotor 7. Die Pendel  achse, die zweckmässig durch ein die An  triebswelle 4, sowie die Getriebe 2, 3 und  5, 6 umschliessendes Gehäuse 4a gebildet       wird,    ist um die Linie Y schwenkbar, da  durch, dass sie mit Ansätzen 8 an feste  Teile 9 des Fahrgestelles angelenkt ist, die  mit dem Fahrzeugrahmen beziehungsweise  Wagenkasten 10 verbunden sind. Die Ge  samtlänge d der Pendelachse ist somit we  sentlich grösser als bei den üblichen Pendel  achsen.  



  Durch die Getriebe 2, 3 werden die zu  einem Radpaar gehörigen Antriebswellen  nebst Pendelachsen in wagrechter Richtung  so weit auseinander gesetzt, dass zwischen  ihnen in der Längsrichtung reichlich Raum  zum Ausschwingen vorhanden ist und sich  trotzdem die Lagerzapfen beider Räder in  der gleichen senkrechten Querebene befinden.  Der Raum zwischen den beiden Antriebs  wellen ist sogar so gross, dass die Motoren 7,  wie ersichtlich, zwischen ihnen Platz finden.  Befinden sich die Enden der Antriebswellen 4  nebst den Ritzeln 3 in der gleichen Höhe  wie die Lagerzapfen der Räder nebst den  Zahnrädern 2, wie dies beim Ausführungs  beispiel nach Fig. 1 und 2 'der Fall ist, so  ist unterhalb der Sitzbänke ausreichend Platz  für die Motoren vorhanden.

   Die Höhe V1  des Bodens des Mittelganges ist, wie ersicht-    lieh, viel niedriger als die Höhe V unter  den Sitzen, wodurch der ganze Wagenkasten  tiefer liegt, als wenn die Motoren in der  Fahrgestellmitte angeordnet und die Pendel  achsen gleichfalls in der Fahrgestellmitte  angelenkt sind.  



  Ordnet man, wie in Fig. 3 dargestellt,  die Ritzet 3 an den Enden der Wellen 4  tiefer als die Lagerzapfen der Laufräder 1  und der Zahnräder 2 an, so ergibt sich eine  weitere wesentliche Verringerung der Höhe V'  des Bodens unterhalb der seitlichen Sitze  und der Höhe V'1 des Bodens des Mittel  ganges.  



  Die angegebenen Ausführungsformen ha  ben auch noch den Vorteil, dass die Achsen  vollkommen gleich gestaltet sind. Anstatt  Pendelachsen können naturgemäss auch an  dere Radlagereinrichtungen vorgesehen sein,  bei denen die Räder voneinander unabhängig  abgefedert sind.



  Motor chassis, in particular for trolley buses and similar vehicles. The invention relates to motor chassis, in particular for trolley buses and similar vehicles with wheels, which are independently sprung and each provided with a special drive motor. In the known chassis the water type, the drive motors are arranged near the inner end of the half-axes of the wheels extending approximately over half the chassis width.

   Since the mass of the drive motors are quite considerable, especially for heavy buses, the specified arrangement of the motors requires a lot of space especially in the middle of the chassis and thus requires a high lying car body floor, so high car body and overall focus. However, with trolley buses and similar vehicles in particular, the lowest possible position of the floor of the vehicle, especially in the middle of the vehicle, where the walkway between the seats is, is extremely desirable. A deep arrangement of the car body floor is made possible according to the invention in that the motors are arranged laterally away from the center of the chassis.



  The drive motors of the wheels and the associated wheels are expediently arranged on different sides of the chassis center and the wheels are mounted on pendulum axles that are longer than half the chassis width, with each drive motor on the pendulum axle of the associated wheel between this wheel and the from the wheel from beyond the chassis center pivot point of the Pen delachse is preferably arranged in the immediate vicinity of the same.



  The motors can also be arranged on the side of the center of the chassis facing away from the associated wheels, however, so that the articulation points of the pendulum axles are between the motors and the wheels they drive, so that the weights acting on both sides of the articulation point the pendulum axis is at least partially balanced.



  In the drawing, for example, embodiments of the subject matter of the invention are illustrated, namely FIG. 1 shows an embodiment in outline, partially in section, FIG. 2 shows this embodiment in end view and FIG. 3 shows a slightly modified embodiment with ending below the wheel bearing journal Drive shafts.



  Each of the wheels 1 of the chassis is through a spur gear 2, 3, a drive shaft 4 and possibly a second spur gear 5, 6 in connection with an electric motor 7. The pendulum axis, which is expediently driven by a drive shaft 4, and the gear 2, 3 and 5, 6 enclosing housing 4a is formed, is pivotable about the line Y, because it is articulated with lugs 8 to fixed parts 9 of the chassis, which are connected to the vehicle frame or car body 10. The total length d of the pendulum axis is therefore much greater than that of the usual pendulum axes.



  The gears 2, 3 set the drive shafts belonging to a pair of wheels together with pendulum axles so far apart in the horizontal direction that there is plenty of space between them in the longitudinal direction and the journals of both wheels are nevertheless in the same vertical transverse plane. The space between the two drive shafts is even so large that the motors 7, as can be seen, find space between them. Are the ends of the drive shafts 4 and the pinions 3 at the same height as the journals of the wheels and the gears 2, as is the case with the execution example according to FIGS. 1 and 2 ', there is enough space below the bench seats Motors available.

   The height V1 of the floor of the aisle is, as can be seen borrowed, much lower than the height V under the seats, whereby the entire car body is lower than if the motors are arranged in the center of the chassis and the pendulum axes are also hinged in the center of the chassis.



  If, as shown in FIG. 3, the scoring 3 at the ends of the shafts 4 is arranged lower than the bearing journals of the running wheels 1 and the gears 2, there is a further substantial reduction in the height V 'of the floor below the side seats and the height V'1 of the floor of the central corridor.



  The specified embodiments also have the advantage that the axes are designed in exactly the same way. Instead of pendulum axles, other wheel bearing devices can of course also be provided in which the wheels are independently sprung.
