Abstract
Description
Die Erfindung betrifft eine elektrische Antriebseinheit für ein Flurförderzeug mit zumindest einem Elektromotor, einer Elektronikeinheit sowie einem Lüfterrad entsprechend dem Oberbegriff des Anspruchs 1.The The invention relates to an electric drive unit for an industrial truck with at least one electric motor, an electronic unit as well a fan according to the preamble of claim 1.
Solche Antriebseinheiten sind bekannt aus Flurförderzeugen, bei denen ein Fahrzeugrad durch einen Antriebsmotor angetrieben und durch einen Lenkmotor gelenkt werden.Such Drive units are known from industrial trucks, where a vehicle wheel driven by a drive motor and by a steering motor be steered.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine kompakte Antriebseinheit für ein Flurförderzeug zu schaffen, bei der die Wärmeabfuhr weiter verbessert wird.Of the present invention is based on the object, a compact Drive unit for an industrial truck to create, where the heat dissipation continues is improved.
Erfindungsgemäß wird dies durch eine Anordnung eines Lüfterrades und eines speziell geformten Deckels erreicht, wodurch eine zirkulare Luftströmung an der Außenwand des Antriebssystems ermöglicht wird. Dadurch wird die Wärmeabfuhr im Vergleich zum Stand der Technik weiter verbessert, da der vom Lüfterrad geförderte Luftstrom über eine längere Strecke an der radialen Außenwand des Antriebssystems entlang strömt und somit mehr Wärme aufnehmen kann. Das Antriebssystem wird also besser gekühlt.According to the invention this is by an arrangement of a fan wheel and reaches a specially shaped lid, creating a circular airflow on the outside wall of the drive system allows becomes. This will heat dissipation in comparison to the prior art further improved since the of fan funded Airflow over a longer one Distance at the radial outer wall of the drive system flows along and thus absorb more heat can. The drive system is therefore better cooled.
Der Deckel besitzt erfindungsgemäß auf seiner dem Lüfterrad zugewandten Innenfläche eine Anzahl an Kühlrippen oder Luftleitelementen, welche in tangentialer Richtung gewölbt sind. Das Lüfterrad fördert aus axialer Richtung ein Luftstrom, den es in radialer Richtung wieder abgibt. Durch die Luftleitelemente des Deckels wird dieser Luftstrom in tangentialer Richtung umgelenkt. Die Innenfläche des Deckels ist weiterhin so gewölbt, dass der Luftstrom in axialer Richtung umgelenkt wird. Die Wölbung der Innenfläche ist so ausgeführt, daß das radiale äußere Ende der Innenfläche in Richtung zu dem mindestens einen Elektromotor bzw. zu einer ersten axialen Außenwand des Antriebsystems gerichtet ist. Die Innenfläche des Deckels ist also vorteilhafter Weise konkav ausgebildet, wobei die Krümmung gleichmäßig und/oder auch stufenweise ausgeführt sein kann. Durch die Wölbung der Innenfläche des Deckels zusammen mit der Wölbung der Luftleitelemente wird ein zirkular fließender Luftstrom ermöglicht, welcher durch Austrittsöffnungen aus dem Gehäuse des Antriebssystems austritt und in zirkularer Richtung um die Außenseite des Antriebsystems strömt. Diese Strömung nimmt Wärme der Antriebseinheit auf und gibt sie an die Umgebung ab.Of the Lid has according to the invention on his the fan wheel facing inner surface a number of cooling fins or air guide elements which are curved in the tangential direction. The fan promotes axial direction, an air flow, it in the radial direction again emits. By the air guide elements of the lid of this air flow deflected in the tangential direction. The inner surface of the lid is still so arched, that the air flow is deflected in the axial direction. The vaulting of the palm is executed that this radial outer end the inner surface in the direction of the at least one electric motor or to a first axial outer wall of the drive system is directed. The inner surface of the lid is therefore more advantageous Concave manner, the curvature evenly and / or also executed stepwise can be. Through the vault the inner surface of the lid together with the curvature the air guide elements enable a circularly flowing air flow, which through outlet openings out of the case of the drive system and in a circular direction around the outside of the drive system flows. This flow takes heat the drive unit and gives it off to the environment.
Der Deckel besitzt in seiner Mitte einen axialen Durchbruch, durch den das Lüfterrad Luft ansaugen kann. Auf der dem Lüfterrad abgewandten Außenseite des Deckels sind in einer weiteren Ausgestaltung Teile der Elektronikeinheit des Antriebsystems wie bspw. Leistungselektronik und/oder Steuerelektronik angebracht. Dadurch werden die Teile der Elektronikeinheit gut gekühlt. Das Lüfterrad ist vorteilhafter Weise koaxial oder achsparallel zu mindestens einem der Elektromotoren ausgerichtet.Of the Lid has in its center an axial opening through which the fan wheel Can suck in air. On the outside of the fan wheel of the lid are parts of the electronic unit in a further embodiment the drive system such as power electronics and / or control electronics appropriate. As a result, the parts of the electronics unit are well cooled. The fan is advantageously coaxial or axially parallel to at least aligned with one of the electric motors.
In einer vorteilhaften Ausgestaltung ragt eine der Antriebswellen des Antriebsystems durch eine erste axiale Außenwand hindurch und ist drehfest mit dem Lüfterrad verbunden. In einer weiteren Ausgestaltung wird das Lüfterrad von einem separaten Antrieb angetrieben. Dadurch kann die Kühlleistung unabhängig von der Drehzahl der Antriebsmotoren geregelt werden.In an advantageous embodiment, one of the drive shafts of the Drive system through a first axial outer wall and is non-rotatable with the fan connected. In a further embodiment, the fan is driven by a separate drive. This can reduce the cooling capacity independently be controlled by the speed of the drive motors.
