Abstract

A device for the arbitrary triggering of the raising and lowering of the vehicle body in relation to at least one vehicle axle on a truck with air suspension is described, the control device of which can be activated not only directly by way of a selector switch arranged in the driver's cab, but also indirectly by means of infrared remote control.

Description

Die Erfindung betrifft eine Einrichtung gemäß dem Ober­ begriff des Anspruches 1.The invention relates to a device according to the Ober Concept of claim 1.

Eine derartige Einrichtung ist aus der DE-OS 35 06 179 bekannt, wobei eine solche Einrichtung in bekannterweise noch so modifiziert sein kann, daß über den externen An­ schluß ein Handbediengerät mit Spiralkabel angeschlossen werden kann. Dies hat den Vorteil, daß ein leichteres An­ passen des Fahrzeugaufbaues in der Höhe an eine Laderampe oder bei einem Wechselpritschenbetrieb für die Bedienperson möglich ist, da sie von außerhalb des Fahrerhauses den Ort des Geschehens leichter einsehen kann. Als nachteilig kann bei dieser Art Fernbedienung erachtet werden, daß auf Grund der begrenzten Länge des Spiralkabels der Aktionskreis der Bedienperson eingeschränkt ist, bezüglich der Unter­ bringung des Kabels im Einstiegsbereich links neben dem Fahrersitz Probleme für die Bedienperson bestehen - Stolper­ gefahr - und bei der Handhabung der Fernbedienung ein Ein­ quetschen des Kabels an der Tür möglich ist, wenn die Fahrer­ tür zugeschlagen wird.Such a device is known from DE-OS 35 06 179, such a device can be modified in a known manner so that a hand control device with a spiral cable can be connected via the external connection. This has the advantage that an easier fit to the vehicle body in the height of a loading ramp or in an interchangeable platform operation is possible for the operator, since it can more easily see the place of action from outside the cab. A disadvantage of this type of remote control can be considered that, due to the limited length of the spiral cable, the action circle of the operator is restricted, with regard to the accommodation of the cable in the entry area to the left of the driver's seat there are problems for the operator - stumbling hazard - and handling the remote control can pinch the cable on the door if the driver's door is slammed shut.

Aufgabe der Erfindung ist es für die eingangs genannte Einrichtung eine problemlose Fernbedienung zu schaffen.The object of the invention is for the aforementioned Establishment to create a hassle-free remote control.

Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst, wobei die Merkmale der Unteransprüche vorteilhafte Ausgestaltungen und Weiter­ bildungen kennzeichnen.This object is achieved with the characteristic Features of claim 1 solved, the features of Advantageous refinements and further mark education.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.

Bei dem in der Zeichnung dargestellten Lastkraftwagen ist mit 1 das Fahrerhaus, mit 2 der Fahrzeugaufbau, mit 3 die Hinterachse und mit 4 die Vorderachse bezeichnet. Zwischen der Vorder- und/oder Hinterachse und dem Fahrzeugaufbau ist in bekannterweise eine nicht dargestellte Niveauregelung eingebaut, mittels welcher der Fahrzeugaufbau gegenüber mindestens einer Achse angehoben oder abgesenkt werden kann. Die Niveauregelung weist ein Schaltventil auf, welches von einer Steuereinrichtung 5 - welche im Bereich des Fahrer­ sitzes innerhalb des Fahrerhauses 1 angeordnet ist - ange­ steuert werden kann, wenn dieselbe durch Betätigen eines Wahlschalters 6 mit Stellungen für das Heben und Senken aktiviert wird. Die Steuereinrichtung 5 und der Wahlschalter 6 bilden hierbei eine Einheit, welche von einer Bedienperson 7 gut zugänglich im vorgenannten Bereich angeordnet ist. Die Steuereinrichtung 5 weist ferner einen externen Anschluß 8 auf, welcher einerseits über eine elektrische Verbindung 9 mit einer Infrarot-Empfänger-Diode 10 und andererseits mit einem in die Steuereinrichtung 5 integrierten Empfänger 11 verbunden ist. Im Beispiel ist die Diode 10 im fahrer­ seitigen Außenspiegel 12 angeordnet, was insofern von Vor­ teil ist, als zum einen der Außenspiegel 12 die Kontur des Fahrzeuges überragt und somit die Diode 10 günstig vom Infrarot-Sender 13 innerhalb eines weiten Aktions­ kreises der Bedienperson 7 angestrahlt werden kann und zum anderen sich der ohnehin vorhandene Kabelkanal zur elektrischen Leitungsverlegung für die Beheizung des Außenspiegels zur Verlegung der elektrischen Verbindung 9 anbietet. Alternativ könnte die Diode 10 auch im Eck­ bereich 1′ der Rückwand des Fahrerhauses 1 angeordnet sein.In the truck shown in the drawing, 1 denotes the driver's cab, 2 the vehicle body, 3 the rear axle and 4 the front axle. Between the front and / or rear axle and the vehicle body, a level control, not shown, is installed in a known manner, by means of which the vehicle body can be raised or lowered with respect to at least one axle. The level control has a switching valve, which can be controlled by a control device 5 - which is arranged in the area of the driver's seat within the cab 1 - when the same is activated by actuating a selector switch 6 with positions for lifting and lowering. The control device 5 and the selector switch 6 form a unit, which is arranged in an easily accessible manner in the aforementioned area by an operator 7 . The control device 5 also has an external connection 8 , which is connected on the one hand via an electrical connection 9 to an infrared receiver diode 10 and on the other hand to a receiver 11 integrated in the control device 5 . In the example, the diode 10 is arranged in the driver-side outside mirror 12 , which is in part of the fact that on the one hand the outside mirror 12 projects beyond the contour of the vehicle and thus the diode 10 is cheap from the infrared transmitter 13 within a wide range of actions of the operator 7 can be illuminated and, on the other hand, the cable channel, which is present anyway, is available for laying the electrical lines for heating the exterior mirror for laying the electrical connection 9 . Alternatively, the diode 10 could also be arranged in the corner area 1 'of the rear wall of the cab 1 .

Neben einer direkten Aktivierung der Steuereinrichtung 5 mittels des Wahlschalters 6 hat nun die Bedienperson 7 auch die Möglichkeit, sich vom Fahrerhaus 1 zu entfernen und unmittelbar an einer Laderampe 14 von dort aus die Steuereinrichtung 5 indirekt mittels des Infrarot-Senders 13 zu aktivieren. Eine exakte Anpassung des Fahrzeugaufbaues an die Höhe der Laderampe unter Ausschluß irgendwelcher Gefährdungen ist somit möglich.In addition to a direct activation of the control device 5 by means of the selector switch 6 , the operator 7 now also has the possibility of moving away from the driver's cab 1 and of activating the control device 5 indirectly from there directly on a loading ramp 14 by means of the infrared transmitter 13 . An exact adaptation of the vehicle body to the height of the loading ramp while excluding any hazards is possible.

Um Fehlauslösungen an der Steuereinrichtung 5 durch Fremd­ strahlung zu verhindern, strahlt der Infrarot-Sender 13 codierte Signale ab, welche vom Empfänger 11 entsprechend decodiert werden.In order to prevent false triggers on the control device 5 due to external radiation, the infrared transmitter 13 emits coded signals which are decoded accordingly by the receiver 11 .

Nach Abschluß der Höhenanpassung des Fahrzeugaufbaues an die Laderampe kann der Infrarot-Sender 13 von der Be­ dienperson 7 in einer Lageraufnahme 15 an der Steuerein­ richtung 5 abgelegt werden.After completing the height adjustment of the vehicle body to the loading ramp, the infrared transmitter 13 can be stored by the operator 7 in a bearing 15 on the Steuerein device 5 .
