Zuladungswaage zum Einbau in einen LKW Aufgabe: Die Zuladungswaage soll dem Fahrer eines LKW den Beladungszustand seines LKW anzeigen, ohne das er auf eine stationäre Waage fahren muß. Sie soll nachträglich in einen vorhandenen LKW eingebaut werden.Load scale for installation in a truck Task: The load scale should show the driver of a truck the load status of his truck without him must drive on a stationary scale. It should be retrospectively integrated into an existing one Trucks can be installed.

Zweck: Durch die Erfindung soll eine oft unbemerkte, die Verkehrssicherheit beeinträchtigende Überladung eines LKW vermieden werden.Purpose: The invention aims at an often unnoticed, traffic safety Detrimental overloading of a truck can be avoided.

Lösung: Zur Messung der Zuladung wird die von der Zuladung abhängige Einfederung,bzw. der Luftdruck bei luftgefederten Fahrzeugen erfaßt. Dies geschieht über je einen Meßwertaufnehmer an der Vorder-und Hinterachse.Solution: To measure the payload, the payload-dependent one is used Spring deflection or the air pressure is recorded in vehicles with air suspension. this happens via one transducer each on the front and rear axles.

Die Addition beider Meßwerte ergibt die Gesamtzuladung. Auf diese Weise wird ein Meßfehler durch ungleichmäßige Beladung vermieden. The addition of the two measured values results in the total payload. To this In this way, a measurement error due to uneven loading is avoided.

Die Meßwertaufnehmer werden zwischen der jeweiligen Achse und dem Chassis des LKW montiert. The transducers are between the respective axis and the Chassis of the truck mounted.

Der Widerstand des im Meßwertaufnehmer eingesetzten Mehrgang-Präzisionspotentiometers ist ein Maß für die Einfederung für die entsprechende Achse. Die Auswertung dieses Widerstandes geschieht in einem Auswerte-Anzeigegerät.Die Addition der beiden beladungsabhängigen Widerstände der an der Vorderachse und Hinterachse des LKW angebrachten Meßwertaufnehmer geschieht durch Reihenschaltung dieser Widerstände. Die Summe beider Widerstände wird mit Hilfe einer Brückenschaltung ausgewertet und angezeigt.Dabei läßt sich durch zwei Einstellpotentiometer der Nullpunkt ohne Beladung und die Beladungsanzeige bei maximal zulässiger Beladung einstellen. The resistance of the multi-turn precision potentiometer used in the transducer is a measure of the deflection for the corresponding axle. The evaluation of this Resistance happens in an evaluation display device. The addition of the two load-dependent Resistances of the transducers attached to the front and rear axles of the truck is done by connecting these resistors in series. The sum of both resistances is evaluated and displayed with the help of a bridge circuit the zero point without load and the load display using two setting potentiometers set at maximum permissible load.

Die Brückenschaltung wird von einer durch einen Festspannungsregler stabilisierten Spannung versorgt, damit Spannungsschwankungen des LKW-Bordnetzes keinen Einfluß auf das Meßergebnis haben. The bridge circuit is operated by a fixed voltage regulator stabilized voltage is supplied, thus voltage fluctuations in the truck electrical system have no influence on the measurement result.

Wenn die Summe der Widerstände der Meßwertaufnehmer über einen A/D-Wandler digitalisiert wird bzw. digital aufgebaute Meßwertaufnehmer eingesetzt werden,läßt sich auch ein digital arbeitendes Auswerte-u.Anzeigegerät aufbauen.in einem derartigen Gerät läßt sich die Beladungs-Federwegcharakteristik nach einmaliger Ermittlung in einen Speicher abspeichern und danach in die digitale Anzeige einrechnen. When the sum of the resistances of the transducers via an A / D converter is digitized or digitally constructed transducers can be used a digital evaluation and display device can also be set up in one of these Device can determine the load-spring deflection characteristics after a one-off determination save it in a memory and then calculate it in the digital display.
