Description

Die Erfindung bezieht sich auf ein batteriegetriebenes Flurförderzeug nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a battery-powered industrial truck according to the preamble of claim 1.

Aus der DE 29 32 668 A1 ist ein batteriegetriebener Hublader bekanntgeworden, bei dem der unterhalb des Sitzes angeordnete Batterieraum durch eine Haube abgedeckt ist, die zugleich den Sitz trägt. Die Haube ist am hinteren Ende des Fahrzeugs um eine horizontale Achse schwenkbar gelagert. Neben dem Sitz ist ein handbetätigtes Steuerorgan zum Beispiel für ein Steuerventil zur Betätigung der Hubeinrichtung angeordnet. Die seitliche Anordnung der Betätigungsvorrichtung ist ergonomisch besonders vorteilhaft. Sie hat jedoch den Nachteil, daß sie entweder den Batterieraum überdeckt oder diesen entsprechend einschränkt. Da die Batterie zu Aufladezwecken wiederkehrend nach oben entnommen wird, ist ein einwandfreier schneller Zugang erforderlich. Aus der DE-29 11 996 ist daher auch bereits bekanntgeworden, die pultartige Betätigungsvorrichtung mittels eines Lagerarms schwenkbar zu lagern. Im Fall eines Zugangs zum Batterieraum wird das Pult nach vorn verschwenkt und eine Batterieabdeckhaube nach hinten.From DE 29 32 668 A1, a battery-operated lift charger has become known, in which the battery space arranged below the seat is covered by a hood which also supports the seat. The hood is pivotally mounted about a horizontal axis at the rear end of the vehicle. In addition to the seat, a manually operated control element is arranged, for example for a control valve for actuating the lifting device. The lateral arrangement of the actuating device is particularly advantageous ergonomically. However, it has the disadvantage that it either covers the battery space or limits it accordingly. Since the battery is removed repeatedly for charging purposes, perfect quick access is required. From DE-29 11 996 it has therefore also become known to pivotally mount the desk-like actuating device by means of a bearing arm. In the event of access to the battery room, the console is swiveled forward and a battery cover is moved backwards.

Bei dem zuletzt erwähnten batteriegetriebenen Hublader ist das Hydraulikventil ebenfalls im Steuerpult angeordnet und wird von mindestens einem Steuerhebel betätigt. Die Anordnung des Hydraulikventils im Steuerpult hat zur Folge, daß die Hydraulikleitungen zu- und abgeführt werden müssen. Dies ist mit einem erheblichen Aufwand verbunden. Außerdem werden die Hydraulikleitungen oder -schläuche beim Verschwenken der Betätigungsvorrichtung mitverschwenkt, was zu einer Belastung der Hydraulikleitungen führt, insbesondere an ihren Anschlußstellen.In the last-mentioned battery-operated lift loader, the hydraulic valve is also arranged in the control panel and is actuated by at least one control lever. The arrangement of the hydraulic valve in the control panel means that the hydraulic lines have to be fed in and out. This is associated with considerable effort. In addition, the hydraulic lines or hoses are also pivoted when the actuating device is pivoted, which leads to a load on the hydraulic lines, in particular at their connection points.

Die US-A-4 238 008 offenbart die Verwendung eines Steuerventils unterhalb der Trittfläche und die Betätigung des Steuerventils über ein Gestänge. Die bekannte Vorrichtung hat getrennte Schwenkachsen für das Gestänge einerseits und den Lagerarm andererseits. Bei einer festen Verkoppelung der Hebel wird daher der Betätigungshebel verschwenkt, wenn der Lagerarm verschwenkt werden soll. Dadurch ist der Verschwenkwinkel des Lagerarms begrenzt durch den Verschwenkweg des Betätigungshebels. In jedem Fall kann nicht vermieden werden, daß bei der Verschwenkung des Lagerarms eine Kraft auf das Steuerventil ausgeübt wird. Ferner kann bei der bekannten Steuerventilbetätigung auch nicht dafür gesorgt werden, daß ausschließlich Zug- und Druckkräfte auf die Eingangsbetägigung des Steuerventils wirken.US-A-4 238 008 discloses the use of a control valve below the tread and the actuation of the control valve via a linkage. The known device has separate pivot axes for the linkage on the one hand and the bearing arm on the other. With a fixed coupling of the levers, the actuating lever is therefore pivoted when the bearing arm is to be pivoted. As a result, the pivoting angle of the bearing arm is limited by the pivoting path of the actuating lever. In any case, it cannot be avoided that a force is exerted on the control valve when the bearing arm is pivoted. Furthermore, with the known control valve actuation, it cannot be ensured that only tensile and compressive forces act on the input actuation of the control valve.

Bei einer anderen Ausführungsform der gleichen Druckschrift wird zwar eine Verschwenkung des Betätigungshebels vermieden, wenn der Lagerarm nach vorne geklappt wird. Dadurch ist jedoch eine spielbehaftete Betätigung der Verstellstange erforderlich, die außerdem eine besondere Axialführung benötigt.In another embodiment of the same document, pivoting of the actuating lever is avoided when the bearing arm is folded forward. However, this requires a playful actuation of the adjusting rod, which also requires a special axial guide.

Der Erfindung liegt daher die Aufgabe zugrunde, ein batteriegetriebenes Flurförderzeug zu schaffen, bei dem eine schwenkbare Betätigungsvorrichtung neben dem Fahrersitz zwecks Freigabe des Batterieraums so ausgeführt ist, daß eine einwandfreie und weitgehend spielfreie Betätigung des Steuerventils möglich ist.The invention is therefore based on the object of providing a battery-operated industrial truck in which a pivotable actuating device is designed next to the driver's seat for the purpose of releasing the battery compartment in such a way that a flawless and largely backlash-free actuation of the control valve is possible.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Patentanspruchs 1.This object is achieved according to the invention by the features of patent claim 1.

Beim erfindungsgemäßen Flurförderzeug ist das hydraulische Steuerventil unterhalb der Trittfläche angeordnet und das Stellorgan ist mit dem Steuerventil über eine mechanische Triebverbindung gekoppelt. Erfindungswesentlich ist die zweigeteilte Betätigungsstange, mit oberem und unterem Abschnitt die in einem Schwenkpunkt schwenkbeweglich gekoppelt sind, der mit der Schwenkachse des Lagerarms zusammenfällt. Es ergeben sich dadurch keine Relativbewegungen von Betätigungsstange einerseits und Lager andererseits, wenn der Lagerarm nach vorn geschwenkt wird. Erfindungswesentlich ist schließlich die Anordnung eines sogenannten Viergelenks mit zwei flurförderzeugfesten Achsen in Verbindung mit dem unteren Abschnitt der Betätigungsstange. Ein Viergelenk ist bekanntlich ein Mittel zur Geradführung. Auf diese Weise wird trotz Zweiteilung der Betätigungsstange eine Geradführung des unteren Stangenabschnitts erreicht, der mithin lediglich auf Druck und Zug belastet ist. Entsprechend wirksam ist die Betätigung des Steuerventils von unteren Kurbelarm des Viergelenks, wobei das Viergelenk so ausgelegt ist, daß ein Übersetzungsverhältnis erhalten wird, das dem einer ungeteilten Stange entspricht und dementsprechend günstig ist; es kommt mithin nicht zu unnötig hohen Betätigungskräften. Das Steuerventil kann in seiner Einbaulage beliebig sein. Insbesondere kann es auch horizontal eingebaut werden, was besonders platzsparend ist.In the industrial truck according to the invention, the hydraulic control valve is arranged below the tread surface and the actuator is coupled to the control valve via a mechanical drive connection. Essential to the invention is the two-part actuating rod, with an upper and a lower section which are pivotally coupled at a pivot point which coincides with the pivot axis of the bearing arm. This results in no relative movements of the operating rod on the one hand and the bearing on the other hand when the bearing arm is pivoted forward. Finally, the arrangement of a so-called four-bar linkage with two axles fixed to the industrial truck in connection with the lower section of the actuating rod is essential to the invention. A four-bar linkage is known to be a means of straight guidance. In this way, a straight guide of the lower is in spite of the actuation rod being divided in two Bar section reached, which is therefore only subjected to pressure and tension. The actuation of the control valve from the lower crank arm of the four-bar linkage is correspondingly effective, the four-bar linkage being designed in such a way that a transmission ratio is obtained which corresponds to that of an undivided rod and is accordingly inexpensive; there is therefore no unnecessarily high actuation force. The control valve can be in any position. In particular, it can also be installed horizontally, which is particularly space-saving.

Nach einer weiteren Ausgestaltung der Erfindung ist die Betätigungsvorrichtung in einem gehäuse untergebracht, das sich pultförmig oberhalb der einen Fahrersitz tragenden Abdeckhaube erstreckt, die am hinteren Ende des Flürförderzeugs schwenkbar gelagert ist. Der Batterieraum kann daher von der Abdeckhaube komplett geschlossen werden. Es bestehen keine Fingen oder sonstigen Öffnungen, über die Verunreinigungen eindringen können.According to a further embodiment of the invention, the actuating device is accommodated in a housing which extends in the form of a desk above the covering hood which bears a driver's seat and is pivotably mounted at the rear end of the industrial truck. The battery compartment can therefore be completely closed by the cover. There are no fingers or other openings through which contaminants can penetrate.

In den Figuren 1 und 2 ist ein batteriegetriebenes Flurförderzeug, beispielsweise ein Hublader oder Gabelstapler allgemein mit 10a bezeichnet. Man erkennt eine vordere Begrenzung 14 eines Fuß- oder Beinraums 16.In FIGS. 1 and 2, a battery-powered industrial truck, for example a lift truck or forklift truck, is generally designated 10a. A front boundary 14 of a foot or leg space 16 can be seen.

An einem Lagerarm 24 ist am oberen Ende ein pultartiges Gehäuse 26 im rechten Winkel angebracht. Es erstreckt sich im Abstand oberhalb einer nicht gezeigten Haube, auf der der Fahrersitz angebracht ist und die einen Batterieraum abdeckt. Im Gehäuse 26 ist ein Bedienungshebel 28 schwenkbar gelagert.A desk-like housing 26 is attached at a right angle to a bearing arm 24 at the upper end. It extends at a distance above a hood, not shown, on which the driver's seat is attached and which covers a battery compartment. An operating lever 28 is pivotally mounted in the housing 26.

Mit dem Bedienungshebel 28 ist mindestens eine vom Lagerarm aufgenommene Schubstange 60 verbunden, die an ein hydraulisches Steuerventil 38 angelenkt ist.At least one push rod 60 received by the bearing arm is connected to the operating lever 28 and is articulated to a hydraulic control valve 38.

Der Fußraum 16 wird nach unten durch eine Trittfläche 40 abgeschlossen. Der Lagerarm 24 erstreckt sich durch die Trittfläche 40 nach unten.The footwell 16 is closed at the bottom by a tread 40. The bearing arm 24 extends downward through the tread 40.

Die Betätigungsstange 60 ist zweigeteilt in einen oberen geknickten Abschnitt 62, der mit dem Stellhebel 28 verbunden ist und einen unteren Abschnitt 64, der an einem Betätigungshebel 66 für das Steuerventil 38 angelenkt ist. Die Stangenabschnitte 62, 64 sind bei 68 aneinandergelenkt. Die Schwenkachse des Lagerarms 24 befindet sich ebenfalls bei 68. Auf diese Weise kann ein durchgehendes Bodenblech 40 verwendet werden.The operating rod 60 is divided into two parts in an upper bent section 62, which is connected to the actuating lever 28 and a lower section 64, which is articulated on an operating lever 66 for the control valve 38. The Rod sections 62, 64 are hinged together at 68. The pivot axis of the bearing arm 24 is also at 68. In this way, a continuous base plate 40 can be used.

Die Anlenkung bzw. Aufhängung des unteren Abschnitts 64 der Stange 60 ist in Fig. 2 näher dargestellt. Der einen Kurbelarm 66 bildende Betätigungshebel für das Steuerventil 38 ist bei 70 fahrzeugfest angelenkt. Eine nach unten weisende Ausnehmung 72 wirkt mit einer Stange 74 zur Betätigung des Ventils 38 zusammen. Der Kurbelarm 66 ist bei 76 am unteren Ende des Stangenabschnitt 64 angelenkt. Etwas oberhalb des Anlenkpunkts 76 ist ein weiterer einen oberen Kurbelarm 78 bildender Hebel bei 80 am Stangenabschnitt 64 angelenkt. Er ist am anderen Ende bei 82 fahrzeugfest angelenkt. Auf diese Weise ist ein Viergelenk gebildet, das eine Führung bildet für den unteren Stangenabschnitt 64 bei Betätigung des oberen Stangenabschnitts 62 über den Stellhebel 28. Man erkennt, daß der Abstand der Schwenkpunkte 80, 82 größer ist als der zwischen den Schwenkpunkten 70, 76. Auf diese Weise wird erreicht, daß im Punkt 76 ausschließlich Zug- und Druckkräfte wirken, auch wenn bei Betätigung des oberen Stangenabschnitts 62 Querkräfte in den Gelenkpunkt 68 zwischen den Stangenabschnitten 62, 64 eingeleitet werden. Dadurch wird ein Übersetzungsverhältnis zur Betätigung des Steuerventils 38 erhalten, das einer ungeteilten Stange gleicht.The articulation or suspension of the lower section 64 of the rod 60 is shown in more detail in FIG. 2. The actuating lever for the control valve 38, which forms a crank arm 66, is articulated in a vehicle-fixed manner at 70. A downwardly facing recess 72 cooperates with a rod 74 for actuating the valve 38. The crank arm 66 is articulated at 76 at the lower end of the rod section 64. Somewhat above the articulation point 76, another lever forming an upper crank arm 78 is articulated at 80 on the rod section 64. It is articulated at 82 on the other end. In this way, a four-bar linkage is formed, which forms a guide for the lower rod section 64 when the upper rod section 62 is actuated via the actuating lever 28. It can be seen that the distance between the pivot points 80, 82 is greater than that between the pivot points 70, 76. In this way it is achieved that only tensile and compressive forces act at point 76, even if transverse forces are introduced into the articulation point 68 between the rod sections 62, 64 when the upper rod section 62 is actuated. This will make a Get gear ratio for operating the control valve 38, which is like an undivided rod.
