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 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 operating lever which is in operative connection with means for detecting the movement of the operating lever and / or the position of the operating lever, and is mounted 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.Control devices are known with an operating lever which can be moved about an axis or about two axes, and which are used in mobile machines, in particular industrial trucks, such as forklifts. By such known as a joystick control devices functions of a working hydraulics, such as a mast or a fork, are preferably controlled upon actuation of the operating lever.
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.Embodiments of control devices that detect the movements of the operating lever with potentiometers are known. However, since these potentiometers may wear, non-contact control devices are preferably used which detect the movement of the magnet-provided operating lever via magnetic sensors, such as Hall sensors.
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.Since mobile work machines and especially trucks are used outdoors and often do not have a fully enclosed cab or doors to the cab are opened very often or are left permanently open because of the need for frequent boarding and disembarking, the control devices are often the Weather exposed. This can lead in particular by water to corrosion and short circuits 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, usually, the operating lever is provided with a bellows, which prevents ingress of water from the top. It is also known to provide a second sealing bellows as a redundant seal.
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.The disadvantage of this is that this bellows as well as a possible second sealing bellows can tear easily by the constant changing load and the aging of the materials and then no longer fulfills its sealing function. Also, a crack in the bellows is often seen late and accumulating water in the meantime leads to damage that requires an exchange of the entire control device.
Bekannt ist weiter, bei berührungslosen Steuerungsvorrichtungen den Hallsensor in Vergussmasse einzuschließen.It is also known to include in non-contact control devices, 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.A disadvantage of this prior art, however, that accumulating water in a housing of the control device over time can still cause damage and can not protect the mechanics of the storage of the operating lever in this way. Finally, freezing may result in malfunction if accumulated water freezes and the ice restricts mobility or, if moved, results in mechanical damage to the control device.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Steuerungsvorrichtung zur Verfügung zu stellen, die möglichst unempfindlich gegen eindringendes Wasser ist.The present invention has for its object to provide a control device that is as insensitive to water penetration.
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.This object is achieved by a control device for a mobile work machine, in particular a truck with the features of claim 1. Advantageous 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, wobei die Lagerung aus einer oben liegenden Kreuzkulisse und einem unter dieser angeordneten Gegenlager besteht, die zwischen sich eine Lagerungskugel des Bedienhebels führen, wobei die Kreuzkulisse nahe an oder in Führungsflächen für die Lagerungskugel Kanäle zur Ableitung von Wasser nach unten aufweisen.The object is achieved in that is in a control device for a mobile machine, in particular a truck with a movable operating lever, which is operatively connected to means for detecting the movement of the operating lever and / or the position of the operating lever, and mounted in a base plate , In the region of the storage and / or a housing of the control device channels are arranged, the water from the control device derive to the outside, the storage consists of an overhead cross backdrop and an arranged below this abutment, which lead between them a support ball of the operating lever, wherein the cross backdrop close to or in guide surfaces for the bearing ball channels for the discharge of water down.
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.As a result, even if a bellows which protects the operating lever and its storage tears and water can penetrate, water is prevented from accumulating, which can lead to short circuits and corrosion. Rather, the water is quickly dissipated to the outside and thereby prevents this water leads to damage. It is therefore often sufficient, in the case of damage to a bellows, to replace only this bellows and not necessary to replace the entire control device.
Auch wird verhindert, dass angesammeltes Wasser bei Frost gefriert und Eisstücke die Funktion der Steuerungsvorrichtung beeinträchtigen können.It also prevents accumulated water freezes in frost and pieces of ice can affect the function of the control device.
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 a favorable embodiment, the base plate above the storage of the operating lever or a cover of the storage of the operating 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.In most cases, the control device is designed so that the housing has a base plate for mounting the control device on its upper side, or there is a cover on this upper side, which covers the storage of the operating lever. Through an opening in the base plate or cover of the operating lever is 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.Now, if there are channels in the base plate or the cover, which can divert water to the outside and / or side, so in case of damage to the bellows no water can accumulate and only water penetrate into the housing of the control device, directly into the relative small opening for the implementation of the operating lever arrives.
Das Gegenlager kann einen um die Lagerkugel angeordneten Sammelkanal aufweisen, von dem Wasser eventuell über weitere Kanäle nach außen abgeleitet wird.The abutment can have a collection channel arranged around the bearing ball, from which water is possibly discharged via further channels to the 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 the bearing of the operating lever, water can penetrate into the control device and cause damage in the electronics. If directly to the storage of the operating lever, which is designed as a trained on the control lever ball, by means of channels penetrating water is first discharged downwards and then via a mounting ball enclosing the collecting channel to the outside, it can be effectively prevented that water further into the Control device can penetrate. In particular, can not accumulate a larger amount of water, which can penetrate over time, an existing seal.
In günstiger Ausführungsform ist als Mittel 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 a favorable embodiment, a magnet is attached as a means for detecting the movement of the operating lever and / or the position of the operating lever on the operating lever, which cooperates with a magnetic sensor element, in particular a Hall sensor, for detecting the movement and / or position of the operating lever.
Das Magnetsensorelement kann an seiner Oberseite eine flächige Dichtung aufweisen und/oder in Vergussmasse eingebettet sein.The magnetic sensor element may have a flat seal on its upper side and / or be embedded in potting compound.
Vorteilhaft sind alle elektronischen Bauteile zusammen mit dem Magnetsensorelement in einem abgedichteten Bereich angeordnet.Advantageously, all electronic components are arranged together with the magnetic sensor element in a sealed area.
Durch die Zusammenfassung ist eine zuverlässige Abdichtung, beispielsweise durch Eingießen in eine Kunststoffmasse leichter erreichbar.By summarizing a reliable seal, for example, by pouring into a plastic mass easier to achieve.
Vorteilhaft kann von der Oberseite des Magnetsensorelements ein Kanal Wasser nach außen ableiten.Advantageously, a channel can divert water to the outside from the upper side of the magnetic sensor element.
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.Since, starting from this region, the electronics which are particularly sensitive to moisture are arranged in the housing of the control device, the risk of short-circuits and electronic damage is 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 an advantageous embodiment, the housing of the control device on its underside a drain for water and the components contained in the housing are arranged so that water can penetrate to the bottom of the housing on.
Dadurch wird verhindert, dass sich Wasser in dem Gehäuse ansammelt und Bauteile im Wasser stehen könnten.This prevents water from accumulating in the enclosure and allowing components to stand in the water.
