Abstract
Description
Die Erfindung betrifft eine Portalachse nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a gantry axis according to the preamble of Claim 1 closer defined type.
Portalachsen werden häufig in Niederfluromnibussen eingesetzt, um im Omnibus eine möglichst niedrige Einstiegsebene zu schaffen, und hierbei eine ausreichende Gangbreite zu gewährleisten.portal axles become common used in low-floor buses to the bus as low as possible Entry level to create, and here a sufficient aisle width to ensure.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Portalachse zu schaffen, welche sich durch Montagefreundlichkeit auszeichnet und einen direkteren Antrieb vom Untersetzungsgetriebe zur Portalachse ermöglicht.Of the present invention is based on the object, a portal axis to create, which is characterized by ease of installation and a more direct drive from the reduction gear to the portal axle allows.
Die Aufgabe wird mit einer, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden, gattungsgemäßen Portalachse gelöst.The Task is with a, even the characterizing features of the main claim having, generic portal axis solved.
Erfindungsgemäß werden die Portalgetriebe durch eine Achsbrücke verbunden, welche aus mindestens zwei Achsbrückengehäuse besteht. Diese Achsbrückengehäuse sind einerseits miteinander lösbar und andererseits mit den Portalgetrieben verbunden. Die Achsbrückengehäuse können lösbar mit den Portalgetriebegehäusen verbunden oder einstückig mit diesen ausgebildet sein. Im Bereich, in welchem die Achsbrückengehäuse miteinander verbunden sind, ist das Ausgleichsgetriebe angeordnet. Um das Ausgleichsgetriebe im Achsbrückengehäuse zu montieren, weisen die Achsbrückengehäuse im Bereich, in welchem sie verbunden sind, trichterförmige Erweiterungen auf, welche einen Durchmesser des Antriebsrades des Ausgleichsgetriebes radial übersteigen. Des weiteren weist mindestens ein Achsbrückengehäuse eine Öffnung zur Aufnahme des Ausgleichsgetriebes auf, welche dergestalt ausgeführt ist, dass sie das Ausgleichsgetriebe umgibt. Diese Öffnung ist koaxial zu einer Drehachse der Antriebswelle, welche das Ausgleichsgetriebe mit dem Portalgetriebe verbindet, ausgeführt.According to the invention the gantry gearbox is connected by an axle bridge, which consists of at least consists of two axle bridge housing. These Achsbrückengehäuse are on the one hand detachable and on the other hand connected to the portal gears. The axle box can be detachable with the Portal transmission housings connected or in one piece be formed with these. In the area in which the Achsbrückengehäuse with each other are connected, the differential gear is arranged. To the differential to be mounted in the axle bridge housing, have the axle box housings in the area, in which they are connected, funnel-shaped extensions, which radially exceed a diameter of the drive wheel of the differential gear. Furthermore, at least one Achsbrückengehäuse has an opening for receiving the differential gear on, which is executed in such a way that it surrounds the differential. This opening is coaxial with one Rotary axis of the drive shaft, which the differential with the Portal gearbox connects, executed.
In einer weiteren Ausgestaltungsform weist das Achsbrückengehäuse, welches die Öffnung zur Aufnahme des Ausgleichsgetriebes aufweist, eine weitere Öffnung auf, durch welche das Antriebsritzel montierbar ist. Das Ausgleichsgetriebe ist über zwei Lagerstellen im Achsbrückengehäuse gelagert, wobei eine erste Lagerstelle in dem einen Achsbrückengehäuse und eine zweite Lagerstelle in dem anderen Achsbrückengehäuse angeordnet ist.In a further embodiment, the Achsbrückengehäuse, which the opening for receiving the differential gear, a further opening, through which the drive pinion is mountable. The differential is over two bearings are mounted in the axle bridge housing, wherein a first bearing in the one Achsbrückengehäuse and a second bearing point arranged in the other Achsbrückengehäuse is.
Somit ist es möglich, das Ausgleichsgetriebe ohne Demontage der Portalgetriebe zu wechseln. Ebenso ist es nicht notwendig, die Antriebswellen, bei welchen ein Ende in die Portalgetriebe ragt, aus den Portalgetrieben zu entfernen, was die Montage erheblich erleichtert. Ebenso ist es möglich, die Kegelradübersetzung zwischen dem Antriebsritzel und dem Tellerrad des Ausgleichsgetriebes auf einfache Weise umzubauen. Indem die Verbindungsstelle, über welche die beiden Achsbrückengehäuse miteinander verbunden sind, frei wählbar ist, besteht die Möglichkeit, das Antriebsritzel dergestalt anzuordnen, dass das Untersetzungsgetriebe, welches von der Antriebsmaschine angetrieben wird, ohne größere Umlenkung das Antriebsritzel antreiben kann.Consequently Is it possible, to change the differential without dismantling the gantry gear. As well it is not necessary, the drive shafts, in which an end protrudes into the gantry gearbox to remove from the portal gears, which makes the assembly considerably easier. Likewise it is possible the Kegelradübersetzung between the drive pinion and the ring gear of the differential gear easy to rebuild. By the junction over which the two axle box with each other are connected, freely selectable is, there is the possibility to arrange the drive pinion such that the reduction gear, which is driven by the prime mover, without major deflection can drive the drive pinion.
