Erfindungsgemäß sind die Antriebsmotoren in einem nicht parallelen Winkel, insbesondere senkrecht zur Antriebsachse angeordnet. Damit wird der Vorteil erreicht, dass Bauraum in Achsrichtung gewonnen wird. Ferner sind am Achsgehäuse Lagerstellen zur Abstützung einer Hubeinrichtung vorgesehen. Damit wird der Vorteil erreicht, dass aus der Hubeinrichtung resultierende Kräfte direkt und zentral in das Achsgehäuse eingeleitet werden, so dass Kippmomente – wie sie bei einer Abstützung vor der Achse auftreten – vermieden werden. Insofern ergibt sich für das Flurförderzeug eine erhöhte Betriebssicherheit.According to the invention the drive motors in a non-parallel angle, in particular arranged perpendicular to the drive axis. This achieves the advantage that space is gained in the axial direction. Furthermore, on the axle housing Bearing points provided for supporting a lifting device. Thus, the advantage is achieved that resulting from the lifting device Forces are introduced directly and centrally into the axle housing so that tilting moments - as with a support occur in front of the axle - to be avoided. In this respect results an increased for the truck Operational reliability.
In vorteilhafter Ausgestaltung sind die Lagerstellen als zylindrische Abschnitte am Achsgehäuse ausgebildet, welche vorteilhaft von die Hubeinrichtung abstützenden Schellen umfasst werden.In advantageous embodiment, the bearings are cylindrical Sections formed on the axle housing, which are advantageous are included by the lifting device supporting clamps.
Die Antriebsmotoren sind vorteilhaft an das Achsgehäuse angeflanscht und treiben über je eine Kegelradstufe in das Achsgehäuse. An die Kegelradstufe schließt sich in vorteilhafter Ausgestaltung ein Planetengetriebe an, welches koaxial zur Radachse, vorzugsweise innerhalb des Laufrades bzw. der Radnabe angeordnet ist. Dadurch wird weiterer Bauraum in Achsrichtung gewonnen.The Drive motors are advantageously flanged to the axle housing and drive each via a bevel gear in the axle housing. At the bevel gear closes in an advantageous embodiment a planetary gear, which is coaxial with the wheel axle, preferably is disposed within the impeller or the wheel hub. Thereby further space is gained in the axial direction.
In vorteilhafter Ausgestaltung sind die Lagerstellen zur Abstützung der Hubeinrichtung zwischen Laufrad und Antriebsmotor bzw. zwischen Kegelradstufe und Planetengetriebe angeordnet. In diesem Bereich des Achsgehäuses ist nur eine Antriebswelle zwischen Kegelradstufe und Planetengetriebe angeordnet, sodass das Achsgehäuse in diesem Bereich als Lagerstelle mit relativ geringem Lagerdurchmesser ausgebildet werden kann. Vorzugsweise sind zwei Lagerstellen, auf jeder Seite der Achse, angeordnet, sodass die Hubeinrichtung über zwei Lager auf der Antriebsachse abgestützt ist.In an advantageous embodiment, the bearings are arranged to support the lifting device between the impeller and the drive motor or between bevel gear and planetary gear. In this area of the axle housing is only one drive shaft arranged between bevel gear and planetary gear, so that the axle housing can be formed in this area as a bearing with a relatively small bearing diameter. Preferably, two bearing points, arranged on each side of the axle, so that the lifting device is supported by two bearings on the drive axle.
Vorteilhaft weisen die Einzelantriebe für die Laufräder Bremseinrichtungen auf, welche vorteilhaft als Lamellenbremsen ausgebildet und durch einen gemeinsamen, mittig angeordneten Aktuator betätigt werden können. In diesem Falle ist ein gemeinsames Achsgehäuse für beide Einzelantriebe vorteilhaft. Anderenfalls, sofern jeder Einzelantrieb über eine eigene Bremse verfügt, kann das Achsgehäuse geteilt ausgebildet sein, sodass jeder Einzelantrieb ein separates Achsgehäuse aufweist. In diesem Falle sind beide Einzelantriebe gleich ausgebildet und können für beide Seiten der Achse verwendet werden.Advantageous have the individual drives for the wheels brake devices on, which advantageously designed as a disk brakes and by a common, centrally located actuator can be actuated can. In this case, a common axle housing advantageous for both individual drives. Otherwise, if every single drive has its own brake, the axle housing can be divided so that everyone Single drive has a separate axle housing. In this Trap both individual drives are identical and can for Both sides of the axle can be used.
