Abstract

The drive pinion (1) is connected by chain (2) to the drive wheel (3) to drive the portal and the pinion can be swivelled round the center of the wheel (3) to vary the portal adjustment. Additional components include shaft (4) connecting the wheel (3) to the main drive.

Description

Die Erfindung bezieht sich auf eine Portalachse für niederflurige Fahrzeuge, insbesondere Niederflur-Omnibusse, nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a portal axis for low-floor vehicles, especially low-floor buses, according to the one defined in the preamble of claim 1 Art.

Die EP 0 877 672 B1 offenbart eine Portalachse für niederflurige Fahrzeuge, bei welcher ein Ausgleichsgetriebe zwei Abtriebswellen aufweist, welche jeweils ein Antriebs­ ritzel eines Portaltriebs antreiben. Das Antriebsritzel treibt zwei Zwischenräder an, welche ein Abtriebsrad des Portaltriebs antreiben, welches direkt mit dem Radantrieb verbunden ist. Die Zwischenräder zwischen dem Antriebsrit­ zel und dem Abtriebsrad des Portaltriebs sind für die Dreh­ richtung notwendig, da das Abtriebsrad dieselbe Drehrich­ tung wie das Antriebsritzel aufweisen muß. Für verschiedene Anwendungen, z. B. normale Bereifung oder kleine Bereifung des Fahrzeugs, ist es notwendig, den Portalabstand, je nach Fahrzeug, zu verändern. Hierzu ist es notwendig, jeweils eine neue Portalräderkette auszulegen und zu bevorraten.EP 0 877 672 B1 discloses a portal axis for low-floor vehicles, in which a differential gear has two output shafts, each of which has a drive drive the pinion of a portal drive. The drive sprocket drives two idler gears, which is an output gear of the Drive the portal drive, which directly with the wheel drive connected is. The intermediate wheels between the drive rit zel and the driven gear of the portal drive are for the rotation direction necessary, since the driven wheel has the same direction of rotation tion as the drive pinion must have. For different ones Applications, e.g. B. normal tires or small tires of the vehicle, it is necessary to change the portal distance, depending on Vehicle to change. To do this, it is necessary in each case to design and stock a new portal wheel chain.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Portalachse für niederflurige Fahrzeuge zu schaffen, bei welcher der Portalabstand auf einfache Weise variiert werden kann.The present invention is based on the object to create a portal axle for low-floor vehicles, at which the portal distance varies in a simple way can be.

Die Aufgabe wird mit einer, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden, gattungsgemäßen Portalachse für niederflurige Fahrzeuge gelöst. The task comes with one, including the distinctive Features of the main claim, generic Portal axle for low-floor vehicles solved.  

Erfindungsgemäß ist die Portalachse, bis auf den Por­ taltrieb, zu der in der EP 0 877 672 B1 offenbarten Portal­ achse baugleich. Der erfindungsgemäße Portaltrieb besteht aus einem Antriebsritzel, welches mit einer Abtriebswelle des Ausgleichsgetriebes verbunden ist und welches über eine Kette ein Abtriebsrad des Portaltriebs antreibt. Je nach Drehmoment sind verschiedene Kettentypen oder auch Zahnrie­ men möglich. Das Abtriebsrad des Portaltriebs ist direkt mit dem Radantrieb verbunden. Durch Verschwenken des An­ triebsritzels um den Mittelpunkt des Abtriebsrads des Por­ taltriebs ist der Portalabstand auf einfache Weise ein­ stellbar. Durch die Verbindung des Antriebsritzels mit dem Abtriebsrad über eine Kette wird die benötigte Abtriebs­ drehrichtung ohne aufwendige Zwischenräder erreicht.According to the portal axis, except for the por valley drive, to the portal disclosed in EP 0 877 672 B1 identical in construction. The portal drive according to the invention exists from a drive pinion, which with an output shaft of the differential gear and which is connected via a Chain drives an output gear of the portal drive. Depending on Torque are different types of chains or toothed possible. The driven gear of the portal drive is direct connected to the wheel drive. By swiveling the on pinion around the center of the driven gear of the por taltriebs is the portal distance in a simple way adjustable. By connecting the drive pinion with the Output gear via a chain becomes the required output direction of rotation achieved without complex intermediate gears.

Weitere Merkmale sind der Figuren-Beschreibung zu ent­ nehmen.Further features can be found in the description of the figures to take.

Die einzige Figur zeigt einen Schnitt durch den Por­ taltrieb, bei welchem ein Antriebsritzel 1 über eine Ket­ te 2 mit einem Abtriebsrad 3 verbunden ist. Das Abtriebs­ rad 3 ist über eine Welle 4 mit dem Radantrieb verbunden. Der weitere Aufbau der Portalachse ist der EP 0 877 672 B1 zu entnehmen. Somit wird eine Portalachse für niederflurige Fahrzeuge geschaffen, bei welcher der Portalabstand auf einfache und kompakte Weise erreicht wird, wobei das Ab­ triebs- und Antriebsritzel dieselbe Drehzahl aufweisen und der Portalabstand auf einfache Weise variiert werden kann. The single figure shows a section through the Por taltrieb, in which a drive pinion 1 via a Ket te 2 is connected to an output gear 3 . The output wheel 3 is connected via a shaft 4 to the wheel drive. The further structure of the portal axis can be found in EP 0 877 672 B1. Thus, a portal axle for low-floor vehicles is created, in which the portal distance is achieved in a simple and compact manner, the drive and drive pinions having the same speed and the portal distance can be varied in a simple manner.
