Die vorliegende Erfindung betrifft eine Antriebsanordnung für ein Flurförderfahrzeug gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art.The present invention relates to a drive arrangement for a material handling vehicle according to the closer defined in the preamble of
Aus der Druckschrift
Ferner ist aus der Druckschrift
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine lenkbare Antriebsanordnung für ein Flurförderfahrzeug der eingangs genannten Gattung vorzuschlagen, welche unter Beibehaltung des erforderlichen Schwenkbereiches zum Ausführen von Lenkbewegungen kostengünstig mit möglichst geringen Geräuschemissionen eine Drehmomentübertragung realisiert.The present invention is based on the object to propose a steerable drive arrangement for a material handling vehicle of the type mentioned, which realizes a torque transmission cost while maintaining the required pivoting range for carrying out steering movements with the lowest possible noise emissions.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen und den Zeichnungen.This object is achieved by the features of
Es wird eine lenkbare Antriebsanordnung für ein Flurförderfahrzeug mit zumindest einem etwa vertikal ausgerichteten Antriebsmotor vorgeschlagen, der über einen Winkeltrieb als Getriebestufe mit zumindest einer etwa horizontal ausgerichteten Welle zum Antrieb zumindest eines Antriebrades gekoppelt ist, wobei ein verzahnungsloser Winkeltrieb zur Drehmomentübertragung verwendet wird.It is proposed a steerable drive arrangement for a material handling vehicle with at least one approximately vertically oriented drive motor, which is coupled via an angle drive as a gear stage with at least one approximately horizontally oriented shaft for driving at least one drive wheel, wherein a gearless angle drive is used for torque transmission.
Auf diese Weise wird eine lenkbare Antriebsanordnung für ein Flurförderfahrzeug mit einem Winkeltrieb ohne Zahnräder und Verzahnungen realisiert, mit dem bei geringer Geräuschemission kostengünstig ein Drehmoment von dem vertikal angeordneten Antriebsmotor auf eine horizontal ausgerichtete Welle und damit auf das Antriebsrad des Fahrzeuges übertragen wird. Insbesondere bei Antriebsanordnungen, bei denen das Antriebsrad zum Ausführen von Lenkbewegungen um 360° schwenkbar ist, kann die vorgeschlagene Anordnung besonders vorteilhaft eingesetzt werden, da sie besonders bauraumsparend ausführbar ist. Andere Anwendungsmöglichkeiten sind jedoch auch denkbar.In this way, a steerable drive arrangement for a material handling vehicle is realized with an angle drive without gears and teeth, with the low noise emission cost torque is transferred from the vertically arranged drive motor to a horizontally oriented shaft and thus to the drive wheel of the vehicle. In particular, in drive arrangements in which the drive wheel for performing steering movements by 360 ° is pivotable, the proposed arrangement can be used particularly advantageous because it is particularly space-saving executable. Other applications are also conceivable.
Vorzugsweise kann im Rahmen einer bevorzugten Ausführungsvariante der Erfindung vorgesehen sein, dass der zahnräderfreie Winkeltrieb z. B. mehrere Winkelstangen oder dergleichen umfasst, die antriebsseitig und abtriebsseitig in Winkelstangenaufnahmen oder ähnlichem drehbar und längsverschieblich bzw. axial verschiebbar gelagert sind. Beispielsweise kann der Winkeltrieb als antriebsseitige Getriebestufe vorgesehen sein, sodass dieser dann die etwa vertikal ausgerichtete Antriebswelle des Antriebsmotors mit einer horizontal ausgerichteten Zwischenwelle zum Antrieb einer abtriebsseitigen Getriebestufe koppelt. Je nach Ausführung der lenkbaren Antriebsanordnung kann der Winkeltrieb aber auch als abtriebsseitige Getriebestufe fungieren.Preferably, in a preferred embodiment of the invention may be provided that the gear-free angle drive z. B. comprises a plurality of angle bars or the like, which are rotatably mounted on the drive side and the output side in angle rod receptacles or the like and longitudinally displaceable or axially displaceable. For example, the angle drive may be provided as a drive-side gear stage, so that it then couples the approximately vertically oriented drive shaft of the drive motor with a horizontally oriented intermediate shaft for driving a driven-side gear stage. Depending on the design of the steerable drive arrangement, however, the angle drive can also function as a drive-side gear stage.
Gemäß einer nächsten Ausgestaltung der Erfindung kann der Winkeltrieb eine erste Winkelstangenaufnahme oder dergleichen mit der Antriebswelle des Antriebsmotors und eine zweite Winkelstangenaufnahme oder dergleichen mit der Zwischenwelle drehfest verbinden. Vorzugsweise kann jede Winkelstangenaufnahme zum Beispiel etwa zylindrisch oder dergleichen ausgebildet sein, wobei bevorzugt im Inneren jeder Winkelstangenaufnahme zur Führung der zugeordneten Winkelstangen mehrere in einem vorbestimmten Radius verteilt angeordnete Bohrungen oder dergleichen vorgesehen sind. Die Bohrungen können entsprechende Lager, z. B. Gleitlager oder dergleichen, für die Winkelstangen aufweisen. Auf diese Weise ist es möglich, dass jede Winkelstange z. B. mit ihrem Endbereich in der jeweiligen Winkelstangenaufnahme derart gelagert ist, dass eine Drehbewegung der Antriebswelle über die Winkelstangen aufgrund des jeweiligen Freiheitsgrades in eine Drehbewegung der Zwischenwelle übertragen wird, ohne dass verzahnte Getriebeelemente erforderlich sind. Es ist jedoch auch eine andere konstruktive Ausführung der Bauteile des Winkeltriebes denkbar, so dass gleichwohl eine Drehmomentübertragung realisiert wird.According to a next embodiment of the invention, the angle drive can rotatably connect a first angle rod receptacle or the like with the drive shaft of the drive motor and a second angle rod receptacle or the like with the intermediate shaft. Preferably, each angle rod receptacle, for example, approximately cylindrical or the like may be formed, preferably in the interior of each angle rod receptacle for guiding the associated angle rods a plurality of distributed in a predetermined radius arranged holes or the like are provided. The holes can appropriate bearings, z. B. plain bearings or the like, have for the angle bars. In this way it is possible that each angle bar z. B. is mounted with its end portion in the respective angle rod receptacle such that a rotational movement of the drive shaft is transmitted via the angle bars due to the respective degree of freedom in a rotational movement of the intermediate shaft without toothed transmission elements are required. However, it is also another constructive design of the components of the angle drive conceivable, so that nevertheless a torque transmission is realized.
Um die vorgeschlagene Antriebsanordnung möglichst variabel einsetzen zu können, kann zudem vorgesehen sein, dass bei dem verzahnungslosen Winkeltrieb der Winkel der Winkelstangen einstellbar ist. Auf diese Weise kann bei den Winkelstangen nicht nur der bevorzugte Winkel von 90°, sondern jeder beliebige Winkel eingestellt werden.In order to use the proposed drive arrangement as variable as possible, can also be provided that in the gearless Angular drive the angle of the angle bars is adjustable. In this way, not only the preferred angle of 90 °, but any angle can be adjusted in the angle bars.
Eine nächste Ausgestaltung der Erfindung kann vorsehen, dass als abtriebsseitige Getriebestufe vorzugsweise ein Stirnradgetriebe, z. B. mit zumindest einer Stufe verwendet wird, wobei das Stirnradgetriebe antriebsseitig mit der Zwischenwelle und abtriebsseitig mit dem Antriebsrad des Fahrzeuges gekoppelt ist. Um eine geforderte Gesamtübersetzung bei der vorgeschlagenen Antriebsanordnung darstellen zu können, kann beispielsweise vorgesehen sein, dass das Stirnradgetriebe mit zumindest einer Planetenstufe oder dergleichen gekoppelt ist. Es ist auch möglich, dass ein Zugmitteltrieb, z. B. als Riementrieb, Kettentrieb oder Zahnriementrieb eingesetzt wird.A next embodiment of the invention may provide that as the output side gear stage preferably a spur gear, z. B. is used with at least one stage, wherein the spur gear is the drive side coupled to the intermediate shaft and the output side to the drive wheel of the vehicle. In order to represent a required overall ratio in the proposed drive arrangement, it can be provided, for example, that the spur gear is coupled to at least one planetary stage or the like. It is also possible that a traction mechanism, z. B. is used as a belt drive, chain drive or toothed belt drive.
Nachfolgend wird die vorliegende Erfindung anhand der Zeichnung weiter erläutert. Es zeigen:Hereinafter, the present invention will be further explained with reference to the drawings. Show it:
