Abstract
Es wird ein Verfahren zur Berechnung der Serviceintervalle für Flurförderfahrzeuge, insbesondere für elektrisch angetriebene Flurförderfahrzeuge, vorgestellt, bei dem die Fahrleistung des Flurförderfahrzeugs aus den an die Motorsteuerung (4) übermittelten Größen Strom, Spannung und Drehzahl über die Zeit berechnet wird, woraus durch Vergleich mit bekannten Alterungsdaten der eingesetzten Schmierstoffe die Serviceintervalle fahrleistungsabhängig berechnet werden.A method for calculating the service intervals for industrial trucks, in particular for electrically powered industrial trucks, is presented, in which the driving performance of the industrial truck is calculated from the variables current, voltage and rotational speed over time, which are compared with Known aging data of the lubricants used, the service intervals are calculated depending on the mileage.
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Bestimmung der Serviceintervalle für Flurförderfahrzeuge, insbesondere für elektrisch angetriebene Flurförderfahrzeuge gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a method for determining the service intervals for industrial trucks, especially for electrically powered industrial trucks according to the preamble of Claim 1.
Nach dem Stand der Technik werden bei Kraftfahrzeugen, beispielsweise bei PKW's die Serviceintervalle aus gespeicherten Fahrleistungsdaten dynamisch berechnet, wobei der Fahrer über eine entsprechende Anzeige darüber informiert wird. Bei Flurförderfahrzeugen existiert jedoch keine entsprechende Möglichkeit, so dass zeitlich konstante Service- und Wartungsintervalle vorgegeben werden.According to the state of the art In the case of motor vehicles, for example in the case of passenger cars, the service intervals are stored Driving performance data is calculated dynamically, the driver using a corresponding Display about it is informed. For industrial trucks however, there is no corresponding possibility, so that temporally constant service and Maintenance intervals are specified.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Bestimmung der Serviceintervalle für Flurförderfahrzeuge, insbesondere für elektrisch angetriebene Flurförderfahrzeuge, anzugeben, welches eine exakte fahrleistungsabhängige Bestimmung der Serviceintervalle mit möglichst geringem Bauaufwand ermöglicht.The present invention lies based on the task of a method for determining the service intervals for industrial trucks, especially for electrically powered industrial trucks, indicate which is an exact mileage-dependent determination of the service intervals with as little as possible Construction effort allowed.
Diese Aufgabe wir durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Varianten und Vorteile gehen aus den Unteransprüchen hervor.We do this task through the characteristics of claim 1 solved. Further variants and advantages emerge from the subclaims.
Demnach wird vorgeschlagen, aus den Größen Strom, Spannung und Drehzahl die Fahrleistung des Flurförderfahrzeugs über die Zeit zu berechnen. Dies erfordert keine zusätzlichen konstruktiven Maßnahmen, da diese Größen in der Motorsteuerung bzw. in den Motorsteuerungen ohnehin ausgewertet bzw. abgelegt werden.Accordingly, it is proposed from the Sizes current, Voltage and speed the driving performance of the truck over the Time to calculate. This does not require any additional constructive measures because these variables in the motor control or are evaluated or stored in the engine controls anyway.
Da die bei Flurförderfahrzeugen üblicherweise eingesetzten AC-Motore eigene Lage/Drehzahlsensoren aufweisen, werden in vorteilhafter Weise keine zusätzlichen Sensoren zum Erfassen der Daten benötigt. Zudem lässt sich aus den Größen Strom, Spannung, Drehzahl und Zeit auch die aktuelle Fahrzeugmasse näherungsweise berechnen.As is usually the case with industrial trucks AC motors used have their own position / speed sensors advantageously no additional Sensors needed to collect the data. In addition, from the sizes of electricity, Voltage, speed and time also approximate the current vehicle mass to calculate.
Des weiteren wird vorgeschlagen, die Anzahl der Bremsungen durch die Betriebsbremse(n) aus den Drehzahlwerten in Verbindung mit den Bremszeiten zu ermitteln. Auf diese Weise kann die Bremsleistung einer einzelnen Bremsung bestimmt werden. Da die Bremspedale/-hebel mit einem Potentiometer verbunden sind, das die Bremswirkung durch die Fahrmotore steuert, wird auch für die Berechnung der Bremsleistung keine zusätzliche Sensorik benötigt.It is also proposed that the number of braking by the service brake (s) from the speed values to be determined in connection with the braking times. In this way the braking power of a single braking can be determined. There the brake pedals / levers are connected to a potentiometer that The braking effect controlled by the driving motors is also used for the calculation of the Braking power no additional Sensor technology needed.
Gemäß der Erfindung werden diese Größen über die Zeit ausgewertet und gespeichert, so dass das tatsächliche Arbeitsspiel und die Bremsleistung bestimmt werden können. Mittels eines Vergleichs mit bekannten Alterungsdaten der in den Getrieben eingesetzten Schmierstoffe, lässt sich der Zeitpunkt für den notwendigen Schmierstoffwechsel berechnen. Analog dazu kann das Serviceintervall für die Betriebsbremse(n) bestimmt und angezeigt werden.According to the invention, these are Sizes over the Time evaluated and saved so that the actual Working cycle and braking performance can be determined. through a comparison with known aging data of those used in the gearboxes Lubricants, leaves the time for calculate the necessary lubricant change. Similarly, can the service interval for the service brake (s) are determined and displayed.
Das hier vorgestellte Verfahren kann für Getriebe, Getriebe mit integrierten, in Öl laufenden Bremsen sowie für eigenständige in Öl laufende Bremsen angewandt werden.The method presented here can for gears, Gearbox with integrated, in oil running brakes as well as for independent brakes running in oil be applied.
Die gemäß der Erfindung bestimmten Serviceintervalle für notwendige Wartungen/Ölwechsel können bevorzugterweise über ein beispielsweise am Armaturenbrett angeordnetes Display angezeigt werden.Those determined according to the invention Service intervals for necessary maintenance / oil changes can preferably be done via a for example, display arranged on the dashboard.
Die Erfindung wird im folgenden anhand der beigefügten Figur, welche eine schematische Anordnung eines Teils einer Antriebsachse eines elektrisch angetriebenen Flurförderfahrzeugs zeigt, beispielhaft näher erläutert.The invention is illustrated below the attached Figure, which is a schematic arrangement of part of a drive axle of an electrically powered industrial truck shows, explained in more detail by way of example.
