Abstract
Description
Die Erfindung betrifft eine Steuerungsvorrichtung für eine mobile Arbeitsmaschine, insbesondere ein Flurförderzeug. Vor allem betrifft die vorliegende Erfindung eine Steuerungsvorrichtung mit einem bewegbaren Bedienhebel, der mit Mitteln zur Erfassung der Bewegung des Bedienhebels und/oder der Stellung des Bedienhebels in Wirkverbindung steht, und in einer Grundplatte gelagert ist.The The invention relates to a control device for a mobile work machine, in particular an industrial truck. In particular, the present invention relates to a control device with a movable control lever, with means for detection the movement of the operating lever and / or the position of the operating lever is in operative connection, and stored in a base plate.
Bekannt sind Steuerungsvorrichtungen mit einem Bedienhebel, der um eine Achse oder um zwei Achsen bewegt werden kann, und die bei mobilen Arbeitsmaschinen, insbesondere Flurförderzeugen, wie etwa Gabelstaplern, zum Einsatz kommen. Durch solche auch als Joystick bekannte Steuerungsvorrichtungen werden bei Betätigung des Bedienhebels bevorzugt Funktionen einer Arbeitshydraulik, wie zum Beispiel eines Hubgerüsts oder einer Lastgabel, gesteuert.Known are control devices with an operating lever, which is around a Axis or two axes can be moved, and those on mobile Working machines, in particular industrial trucks, such as Forklifts, are used. By such as a joystick Known control devices are activated the operating lever preferably functions of a working hydraulics, such as Example of a mast or a fork, controlled.
Bekannt sind dabei Ausführungen von Steuerungsvorrichtungen, die die Bewegungen des Bedienhebels mit Potentiometern erfassen. Da diese Potentiometer jedoch verschleißen können, kommen bevorzugt berührungslose Steuerungsvorrichtungen zum Einsatz, die über Magnetsensoren, wie etwa Hallsensoren, die Bewegung des mit einem Magneten versehenen Bedienhebels erfassen.Known are embodiments of control devices that detect the movements of the operating lever with potentiometers. There however, these potentiometers can wear out, Preferably, non-contact control devices are used Use that can be achieved by magnetic sensors, such as Hall sensors, detect the movement of the lever provided with a magnet.
Da mobile Arbeitmaschinen und vor allem Flurförderzeuge im Freien zum Einsatz kommen und oftmals kein vollständig geschlossenes Führerhaus aufweisen oder Türen zu dem Führerhaus sehr oft geöffnet werden bzw. permanent offen gelassen werden, wegen der Notwendigkeit des häufigen Ein- und Aussteigens, sind die Steuerungsvorrichtungen oft der Witterung ausgesetzt. Dies kann insbesondere durch Wasser zu Korrosion und Kurzschlüssen in der Elektronik führen und zu einem Versagen der Steuerungsvorrichtung.There mobile work machines and especially industrial trucks in the Outdoors are used and often not complete have closed cab or doors to open the cab very often or to be left permanently open because of the need for frequent Getting in and out, the control devices are often the weather exposed. This can be done especially by water to corrosion and Short circuits lead in the electronics and to a failure of the control device.
Daher wird üblicherweise der Bedienhebel mit einem Faltenbalg versehen, der ein Eindringen von Wasser von der Oberseite verhindert. Auch ist bekannt, einen zweiten Dichtungsbalg als redundante Dichtung vorzusehen.Therefore is usually the operating lever with a bellows provided that prevents ingress of water from the top. It is also known, a second sealing bellows as a redundant seal provided.
Nachteilig daran ist, dass dieser Faltenbalg wie auch ein eventueller zweiter Dichtungsbalg durch die dauernde wechselnde Belastung und die Alterung der Materialien leicht einreißen kann und seine Dichtfunktion dann nicht mehr erfüllt. Auch wird ein Riss in dem Faltenbalg oft erst spät gesehen und sich zwischenzeitlich ansammelndes Wasser führt zu Beschädigungen, die einen Austausch der gesamten Steuerungsvorrichtung erforderlich machen.adversely It is because of this bellows as well as a possible second Sealing bellows by the constant changing load and the aging which can easily tear down materials and its sealing function then no longer fulfilled. Also, there will be a crack in the bellows often seen late and accumulating in the meantime Water leads to damage, an exchange make the entire control device required.
Bekannt ist weiter, bei berührungslosen Steuerungsvorrichtungen den Hallsensor in Vergussmasse einzuschließen.Known is further, with non-contact control devices to include the Hall sensor in potting compound.
Nachteilig an diesem Stand der Technik ist jedoch, dass sich ansammelndes Wasser in einem Gehäuse der Steuerungsvorrichtung mit der Zeit dennoch zu Schäden führen kann und sich die Mechanik der Lagerung des Bedienhebels auf diese Weise nicht schützen lässt. Schließlich kann es bei Frost zu Funktionsbeeinträchtigungen kommen, wenn angesammeltes Wasser gefriert und das Eis die Bewegbarkeit einschränkt oder bei einem Bewegen zu mechanischen Schäden an der Steuerungsvorrichtung führt.adversely However, at this state of the art is that accumulating water in a housing of the control device with time nevertheless can cause damage and the mechanics of Do not protect the operating lever in this way leaves. After all, it can cause functional impairment during frosty weather come when accumulated water freezes and the ice the mobility limits or when moving to mechanical damage leads to the control device.
Aus
der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Steuerungsvorrichtung zur Verfügung zu stellen, die möglichst unempfindlich gegen eindringendes Wasser ist.Of the present invention is based on the object, a control device to provide the most insensitive possible against invading water.
Diese Aufgabe wird durch eine Steuerungsvorrichtung für eine mobile Arbeitsmaschine, insbesondere ein Flurförderzeug mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen werden in den Unteransprüchen angegeben.These Task is by a control device for a mobile work machine, in particular an industrial truck solved with the features of claim 1. advantageous Further developments are specified in the subclaims.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einer Steuerungsvorrichtung für eine mobile Arbeitsmaschine, insbesondere ein Flurförderzeug mit einem bewegbaren Bedienhebel, der mit Mitteln zur Erfassung der Bewegung des Bedienhebels und/oder der Stellung des Bedienhebels in Wirkverbindung steht, und in einer Grundplatte gelagert ist, im Bereich der Lagerung und/oder eines Gehäuses der Steuerungsvorrichtung Kanäle angeordnet sind, die Wasser aus der Steuerungsvorrichtung nach außen ableiten.The The object is achieved according to the invention that in a control device for a mobile work machine, in particular an industrial truck with a movable control lever, with means for detecting the movement of the operating lever and / or the position of the operating lever is in operative connection, and in one Base plate is stored, in the field of storage and / or a Housing the control device channels are arranged divert the water from the control device to the outside.
Dadurch wird, auch wenn ein den Bedienhebel und dessen Lagerung schützender Faltenbalg einreißt und Wasser eindringen kann, verhindert, dass sich Wasser ansammeln kann und dadurch zu Kurzschlüssen und Korrosion führen kann. Vielmehr wird das Wasser rasch nach außen abgeführt und dadurch verhindert, dass dieses Wasser zu Schäden führt. Es ist daher oftmals ausreichend, im Falle der Beschädigung eines Faltenbalges, nur diesen Faltenbalg auszuwechseln, und nicht erforderlich, die gesamte Steuerungsvorrichtung auszutauschen.Thereby is, even if a more protective lever and its storage Bellows tears and water can penetrate, prevents can accumulate water and thus to short circuits and corrosion. Rather, the water is fast dissipated to the outside, thereby preventing that this water leads to damage. It is therefore often sufficient, in case of damage to a bellows, just replace this bellows, and not required, the entire Exchange control device.
Auch wird verhindert, dass angesammeltes Wasser bei Frost gefriert und Eisstücke die Funktion der Steuerungsvorrichtung beeinträchtigen können.Also Prevents accumulated water from freezing and freezing Ice pieces affect the function of the control device can.
In günstiger Ausführungsform weist die Grundplatte oberhalb der Lagerung des Bedienhebels oder eine Abdeckung der Lagerung des Bedienhebels Kanäle zur Ableitung von Wasser auf.In favorable embodiment, the base plate above the storage of the operating lever or a cover of storage of the control lever channels for the discharge of water.
Zumeist ist die Steuerungsvorrichtung so ausgeführt, dass das Gehäuse an seiner Oberseite eine Grundplatte für die Montage der Steuerungsvorrichtung aufweist, oder es ist eine Abdeckung an dieser Oberseite vorhanden, die die Lagerung des Bedienhebels abdeckt. Durch eine Öffnung in der Grundplatte oder Abdeckung ist der Bedienhebel hindurchgeführt und wird üblicherweise mit einem Faltenbalg gegenüber der Grundplatte oder Abdeckung abgedichtet.mostly the control device is designed so that the housing at its top a base plate for the assembly of Control device, or it is a cover on this Top available, which covers the bearing of the control lever. Through an opening in the base plate or cover is the operating lever passed and is usually sealed with a bellows against the base plate or cover.
Wenn nun in der Grundplatte oder der Abdeckung Kanäle vorhanden sind, die Wasser nach außen und/oder Seite ableiten können, so kann sich im Falle einer Beschädigung des Faltenbalges kein Wasser ansammeln und nur Wasser in das Gehäuse der Steuerungsvorrichtung eindringen, das direkt in die relativ kleine Öffnung zur Durchführung des Bedienhebels gelangt.If now available in the base plate or the cover channels are those that can divert water to the outside and / or side, so can damage the bellows in case of damage do not accumulate any water and only add water to the case Control device penetrate directly into the relatively small opening for the implementation of the operating lever arrives.
Vorteilhaft besteht die Lagerung aus einer oben liegenden Kreuzkulisse und einem unter dieser angeordneten Gegenlager, die zwischen sich eine Lagerungskugel des Bedienhebels führen und weist die Kreuzkulisse nahe an oder in Führungsflächen für die Lagerungskugel Kanäle zur Ableitung von Wasser nach unten auf. Das Gegenlager kann einen um die Lagerkugel angeordneten Sammelkanal aufweisen, von dem Wasser eventuell über weitere Kanäle nach außen abgeleitet wird.Advantageous the storage consists of an overhead cross backdrop and a under this arranged abutment, which is a support ball between them lead the control lever and suggests the cross backdrop on or in guide surfaces for the bearing ball Channels for draining water down to. The counter bearing can have a collection channel arranged around the bearing ball, from the water, possibly via other channels is derived outside.
Im Bereich der Lagerung des Bedienhebels kann Wasser in die Steuerungsvorrichtung eindringen und in der Elektronik zu Schäden führen. Wenn direkt an der Lagerung des Bedienhebels, die als eine an dem Bedienhebel ausgebildete Kugel ausgeführt ist, mittels Kanäle eindringendes Wasser zunächst nach unten und sodann über einen die Lagerungskugel umschließenden Sammelkanal nach außen abgeführt wird, so kann effektiv verhindert werden, dass Wasser weiter in die Steuerungsvorrichtung eindringen kann. Insbesondere kann sich nicht eine größere Wassermenge ansammeln, die mit der Zeit auch eine vorhandene Abdichtung durchdringen kann.in the Area of storage of the control lever can add water to the control device penetrate and damage the electronics. When directly attached to the storage of the operating lever, as one on the Control lever trained ball is executed by means of Channels penetrating water first down and then over a bearing ball enclosing Collector channel is discharged to the outside, so can effectively prevents water from entering the control device can penetrate. In particular, can not be a larger one Accumulating amount of water, which over time also an existing seal can penetrate.
In günstiger Ausführungsform ist als Mitteln zur Erfassung der Bewegung des Bedienhebels und/oder der Stellung des Bedienhebels an dem Bedienhebel ein Magnet befestigt, der mit einem Magnetsensorelement, insbesondere einem Hallsensor, zur Erfassung der Bewegung und/oder Stellung des Bedienhebels zusammenwirkt.In favorable embodiment is as means for Detecting the movement of the operating lever and / or the position of the Operating lever attached to the operating lever a magnet that with a Magnetic sensor element, in particular a Hall sensor, for detection the movement and / or position of the operating lever cooperates.
Das Magnetsensorelement kann an seiner Oberseite eine flächige Dichtung aufweisen und/oder in Vergussmasse eingebettet sein.The Magnetic sensor element can on its upper side a flat Have seal and / or embedded in potting compound.
Vorteilhaft sind alle elektronischen Bauteile zusammen mit dem Magnetsensorelement in einem abgedichteten Bereich angeordnet.Advantageous are all electronic components together with the magnetic sensor element arranged in a sealed area.
Durch die Zusammenfassung ist eine zuverlässige Abdichtung, beispielsweise durch Eingießen in eine Kunststoffmasse leichter erreichbar.By the summary is a reliable seal, for example Easier to reach by pouring into a plastic mass.
Vorteilhaft kann von der Oberseite des Magnetsensorelements ein Kanal Wasser nach außen ableiten.Advantageous may be a channel of water from the top of the magnetic sensor element derive to the outside.
Da ab diesem Bereich nach unten hin die gegenüber Feuchtigkeit besonders empfindliche Elektronik in dem Gehäuse der Steuerungsvorrichtung angeordnet ist, wird das Risiko von Kurzschlüssen und Elektronikschäden durch diese Maßnahme verringert.There from this area down towards moisture particularly sensitive electronics arranged in the housing of the control device is, the risk of short circuits and electronics damage reduced by this measure.
In vorteilhafter Ausführungsform weist das Gehäuse der Steuerungsvorrichtung an seiner Unterseite einen Ablauf für Wasser auf und die im Gehäuse enthaltenen Bauteile sind so angeordnet, dass eingedrungenes Wasser bis zur Unterseite des Gehäuses weiter fließen kann.In advantageous embodiment, the housing the control device at its bottom a drain for Water on and the components contained in the housing are arranged so that water has penetrated to the bottom of the Housing can continue to flow.
Dadurch wird verhindert, dass sich Wasser in dem Gehäuse ansammelt und Bauteile im Wasser stehen könnten.Thereby prevents water from accumulating in the housing and components could be in the water.
