Joystick eines ArbeitsfahrzeugsJoystick of a work vehicle

Die Erfindung betrifft ein Arbeitsfahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to a work vehicle according to the preamble of claim 1.

Es sind Flurförderzeuge bekannt, bei denen der Fahrer quer zur Fahrtrichtung sitzt. Die Richtung, in die er das Fahrzeug verfahren will, stellt er mittels eines Hebels, der sich normalerweise am Lenkstock befindet, oder mittels eines Schalters, der sich im Bedienpult der rechten Hand befindet, ein. Die Geschwindigkeit der Fahrt wird - wie vom PKW bekannt - mittels eines Fahrpedals eingestellt. Diese Fahrzeuge haben den Nachteil, daß der Fahrer zum Richtungswechsel die Hand von dem Joystick nehmen muß, mit dem er die Last hebt und senkt.There are industrial trucks where the driver sits across the direction of travel. The direction in which he wants to drive the vehicle is set using a lever, which is usually located on the steering column, or using a switch on the control panel in the right hand. The speed of travel is set using an accelerator pedal, as is the case with cars. These vehicles have the disadvantage that the driver has to take his hand off the joystick, which he uses to raise and lower the load, to change direction.

Aufgabe der Erfindung ist es, ein Arbeitsfahrzeug dahingehend zu verbessern, daß die Bedienabläufe ermüdungsfreier durchgeführt werden können.The object of the invention is to improve a work vehicle so that the operating procedures can be carried out in a more fatigue-free manner.

Diese Aufgabe wird erfindungsgemäß gelöst von einem Arbeitsfahrzeug, bei dem der Joystick, mit dem die Last bewegt, die Gabel gehoben oder die Schaufel gesenkt wird, nun auch zur Vorwahl der Fahrtrichtung eingesetzt wird. Die Erfindung ist besonders gut geeignet für Fahrzeuge, bei denen der Fahrer quer zur Fahrtrichtung sitzt. Bei diesen Fahrzeugen gibt es prinzipiell keine bevorzugte Fahrtrichtung. Der Fahrer mußte bisher zum Richtungswechsel die Hand von dem Bediengerät für die Last nehmen und an einem Lenkstockhebel die Fahrtrichtungsänderung eingeben, bevor er losfahren konnte. Erfindungsgemäß kann der Fahrer nun theoretisch die Hand während des ganzen Arbeitstages an dem Joystick für die Verstellung der Last lassen und kann die Fahrtrichtung durch Antippen, insbesondere durch Antippen in Richtung der gewünschten Fahrtrichtung, vorwählen. This problem is solved according to the invention by a work vehicle in which the joystick used to move the load, raise the fork or lower the bucket is now also used to preselect the direction of travel. The invention is particularly well suited to vehicles in which the driver sits across the direction of travel. In principle, there is no preferred direction of travel in these vehicles. To change direction, the driver previously had to take his hand off the control device for the load and enter the change in direction on a steering column lever before he could drive off. According to the invention, the driver can now theoretically keep his hand on the joystick for adjusting the load throughout the entire working day and can preselect the direction of travel by tapping, in particular by tapping in the direction of the desired direction of travel.

In einer bevorzugten Ausführung ist eine Anzeige vorgesehen, die dem Fahrer visuell darstellt, in welche Fahrtrichtung der Motor vorgewählt ist. Dazu eignen sich insbesondere kleine leuchtende Pfeile, die im Blickfeld des Fahrers angeordnet sind.In a preferred embodiment, a display is provided that visually shows the driver in which direction the motor is preselected. Small illuminated arrows arranged in the driver's field of vision are particularly suitable for this purpose.

Die Erfindung wird anhand einer Figur näher erläutert. Die Figur zeigt schematisch den Fahrerarbeitsplatz in einem Flurförderzeug einmal von hinten gesehen und auf der unteren Bildhälfte von oben gesehen.The invention is explained in more detail using a figure. The figure shows a schematic view of the driver's workplace in an industrial truck, once seen from behind and in the lower half of the picture seen from above.

Das Flurförderzeug F hat an seinem hinteren Ende einen Fahrersitz S, der quer zur Fahrtrichtung angeordnet ist. Vor dem Fahrer befinden sich in an sich bekannter Anordnung das Lenkrad L, der Schlüssel SL für das Anlassen des Fahrzeugs, die Feststellbremse FB, sowie die Pedale P für das Fahren und für das Bremsen. Für die rechte Hand des Fahrers ist ein Joystick J vorgesehen, der vier Stellmöglichkeiten für die Last, hier z.B. Heben, Senken und Verfahren nach vorne und hinten der Gabel vorsehen. Weiter gezeigt sind ein Notausschalter NA sowie Anzeigen A für den Fahrer. Erfindungsgemäß ist nun im Joystick J die Vorwahl für die Fahrtrichtung integriert. Will der Fahrer mit dem Fahrzeug nach vorne fahren, tippt er den Joystick J einmal kurz nach rechts an und sieht auf der Anzeige einen kleinen Pfeil PF, der ihm die gewählte Fahrtrichtung anzeigt. Will der Fahrer nach hinten fahren, tippt er den Joystick J in Gegenrichtung, also nach links an. Auf der Anzeige wechselt der beleuchtete Pfeil PF, der Fahrer erkennt die vorgewählte Richtung und kann mit dem Fahrpedal beschleunigen. Durch die erfindungsgemäße Anordnung der Richtungsvorwahl am Joystick J kann der Fahrer nun theoretisch die Hand während des ganzen Arbeitstages an dem Bedienhebel (Joystick J) lassen, insbesondere, wenn weitere Funktionen, wie die Hupe, im Joystick J integriert sind.The industrial truck F has a driver's seat S at its rear end, which is arranged transversely to the direction of travel. In front of the driver, in a known arrangement, are the steering wheel L, the key SL for starting the vehicle, the parking brake FB, and the pedals P for driving and braking. A joystick J is provided for the driver's right hand, which provides four adjustment options for the load, here e.g. lifting, lowering and moving the fork forwards and backwards. Also shown are an emergency stop switch NA and displays A for the driver. According to the invention, the preselection for the direction of travel is now integrated in the joystick J. If the driver wants to drive the vehicle forwards, he briefly taps the joystick J once to the right and sees a small arrow PF on the display, which shows him the selected direction of travel. If the driver wants to drive backwards, he taps the joystick J in the opposite direction, i.e. to the left. The illuminated arrow PF changes on the display, the driver recognizes the preselected direction and can accelerate using the accelerator pedal. Thanks to the inventive arrangement of the direction preselection on the joystick J, the driver can now theoretically keep his hand on the control lever (joystick J) throughout the entire working day, especially if other functions, such as the horn, are integrated into the joystick J.
