Abstract
Description
Die Erfindung betrifft eine Anzeigevorrichtung für die Stellung von lenkbaren Rädern nach dem Oberbegriff des Hauptanspruches.The invention relates to a display device for the Position of steerable wheels according to the preamble of Main claim.
Aus der DE 40 35 794 A1 ist bereits eine Anzeigevorrich tung für die Stellung von lenkbaren Rädern bekannt, die die Merkmale des Oberbegriffs aufweist. In dieser Druckschrift wird auf aufwendige Weise beschrieben, wie mit Hilfe von Hallgebern eine Vielzahl von LEDs für meh rere lenkbare Räder angesteuert werden. Diese Information mag bei Flurförderfahrzeugen beachtet werden, für norma le Kraftfahrzeuge wird sich jedoch eine derartige Vor richtung als zu komplex erweisen.DE 40 35 794 A1 is already a display device device known for the position of steerable wheels has the features of the generic term. In this Print is described in a complex manner, such as with the help of Hall sensors a variety of LEDs for meh steerable wheels can be controlled. This information may be noted for industrial trucks, for norma le motor vehicles will, however, become such a front direction too complex.
Weiter ist die DE 41 07 130 A1 zu nennen, in der bereits eine Vorrichtung zum Erfassen von Lenkwinkeln anhand der Schaltzustände unterschiedlicher Sensoren an den Achs schenkelbolzen beschrieben wird, sowie die DE 39 08 854 A1 , in der eine Lenkwinkeldetektorvorrichtung mittels Lenkimpulsen, die über einen Zähler geleitet werden, eine Radstellung feststellt.DE 41 07 130 A1 should also be mentioned, in which already a device for detecting steering angles based on the Switching states of different sensors on the axis leg bolt is described, as well as DE 39 08 854 A1 , in which a steering angle detector device by means of Steering impulses that are passed through a counter, one Wheel position.
Den vorgenannten Druckschriften ist gemein, daß sie Vor richtungen beschreiben, die den Fahrer eines Fahrzeugs kontinuierlich über die Stellung seiner Räder informie ren. Aufgabe der Erfindung ist es, darüber hinaus vor Betätigung des Anlassers auf die Stellung der lenkbaren Räder aufmerksam zu machen. Weiterhin soll durch die An zeigevorrichtung auch die Einstellung der Fahrzeugräder beim Verlassen des Fahrzeuges in eine gerade Position ermöglicht werden. Gelöst wird diese Aufgabe durch die Merkmale des Hauptanspruchs.The aforementioned publications have in common that they are pre Describe directions that the driver of a vehicle continuously inform about the position of his wheels ren. The object of the invention is beyond Actuation of the starter to the position of the steerable To draw attention to wheels. Furthermore, the An Show device also the setting of the vehicle wheels when leaving the vehicle in a straight position be made possible. This task is solved by the Features of the main claim.
Die Vorteile der Erfindung bestehen in der Unfallvermei dung und dem Energie sparen beim Ausparken auf engen Parkplätzen. Hier kommt es oft zu unnötigen Personen- und Blechschäden, weil Fahrer beim Anfahren nicht mehr wissen, wie ihre lenkbaren Räder momentan stehen. The advantages of the invention are the accident avoidance and save energy when parking in tight spaces Parking spaces. Here there are often unnecessary people and Damage to the sheet metal because the driver no longer drives when starting know how their steerable wheels are at the moment.
Weiter ist es bei einem abgestellten Fahrmotor bei Fahr zeugen mit Servolenkung schwierig, das Lenkradschloß einzurasten, wenn die Räder nicht gerade stehen. Dies führt dazu, daß ein Fahrer den Motor nochmals starten muß um die Räder gerade zu stellen. Dies gibt bei Mil lionen von Autofahrern einen hohen unnötigen Energiever brauch.It is also when the drive motor is turned off while driving testify with power steering difficult, the steering wheel lock engage when the wheels are not straight. This causes a driver to restart the engine must to straighten the wheels. At Mil lions of drivers have a high unnecessary energy consumption need.
In der beigefügten Zeichnung ist die Funktion der erfin dungsgemäßen Anzeigevorrichtung im Detail dargestellt. Dabei zeigt: In the attached drawing, the function of the invented Display device according to the invention shown in detail. It shows:
Fig. 1 ein Armaturenbrett eines Fahrzeuges mit zusätzlich angeordneter Anzeigevorrich tung, Fig. 1 shows a dashboard of a vehicle with tung additionally arranged Anzeigevorrich,
Fig. 2 eine Explosionsdarstellung einer Fahr zeuglenkung, und Fig. 2 is an exploded view of a driving tool steering, and
Fig. 3 eine Schaltung für die Anzeigevorrich tung. Fig. 3 shows a circuit for the device device.
Die Anzeige in der Fig. 1 besteht aus zwei roten Blink-LED's und einer grünen LED mit Vorwiderständen und ist mit dem Bezugszeichen 1 bezeichnet. Die komplette Steue rung und Anzeige arbeitet mit 12 Volt Gleichspannung.The display in FIG. 1 consists of two red flashing LEDs and a green LED with series resistors and is designated by reference number 1 . The complete control and display works with 12 volts DC.
Die linke rote Blink-LED blinkt, wenn die Räder nach links eingeschlagen sind. Die rechte rote Blink-LED blinkt, wenn die Räder nach rechts eingeschlagen sind. Die grüne LED leuchtet, wenn die Räder gerade stehen.The left red flashing LED flashes when the wheels move are turned left. The right red flashing LED flashes when the wheels are turned to the right. The green LED lights up when the wheels are straight.
Angesteuert werden die LED's von den elektromagnetischen Schaltern 3 (Fig. 2). Angebrachte Metallfahnen am Lenk stockhebel 4 bringen in verschiedenen Positionen diese elektromagnetischen Schalter zum Schalten.The LEDs are controlled by the electromagnetic switches 3 ( FIG. 2). Metal flags attached to the steering column lever 4 cause these electromagnetic switches to switch in different positions.
Ein Photosensor 2, der in der Nähe des Zündschlosses an gebracht ist, schaltet über eine Timerschaltung (10) für eine eingestellte Zeit die Anzeige ein. Wenn der Fahrer die Hand zum Zündschloß hebt und in die Nähe des Schlüs sels kommt, schaltet der Photosensor. Die Timerschaltung ist dabei von 2 s bis 10 min über ein Potentiometer ein stellbar. A photosensor 2 , which is placed near the ignition lock, turns on the display for a set time via a timer circuit ( 10 ). When the driver raises his hand to the ignition lock and comes close to the key, the photosensor switches. The timer circuit can be set from 2 s to 10 min using a potentiometer.
Die Anzeige ist nur aktiv, wenn das Fahrzeug startet oder für eine eingestellte Zeit beim Ausstellen des Mo tors. Ein akustisches Signal aus einem Lautgeber 12 macht den Fahrer zusätzlich zu den optischen Anzeigen der Anzeigeleuchten 14 aufmerksam.The display is only active when the vehicle starts or for a set time when the engine is switched off. An acoustic signal from a loudspeaker 12 notifies the driver in addition to the visual displays of the indicator lights 14 .
Die tatsächliche Ausführung der Erfindung kann auch über einen Getriebeschalter am Lenkgetriebe, einen verstell baren Widerstand mit analoger Anzeige oder andere tech nische Möglichkeiten realisiert werden.The actual implementation of the invention may also be about a gear switch on the steering gear, an adj Resistance with analog display or other tech African possibilities can be realized.
Auch die Einbauorte können überall an der Lenkung oder an den Spurstangen gewählt werden.The installation locations can be anywhere on the steering or be selected on the tie rods.
