Abstract

The corrosion protection which is described prevents corrosion on vehicles and is electrically natural. A dedicated battery is used as the voltage source.

Description

Beschreibung description

Die Erfindung betrifft einen elektrischen Korrosionsschutz an Fahrzeugen, bei denen minuspol der Batterie an das Gehäuse angeschlossen ist.The invention relates to electrical corrosion protection on vehicles, where the negative pole of the battery is connected to the housing.

Es ist bekannt, daß zur Erfüllung dieser Aufgabe verschiedene Möglichkeiten bestehen und die Korrosion meistens mit Lacken und Anstrichen verhindert wird.It is known that to accomplish this task, various possibilities and the corrosion is usually prevented with varnishes and paints.

Es ist mehrmals notwendig, verschiedene Stellen auszubessern, so daß weitere schäden nicht eintreten können.It is necessary several times to touch up different places so that further damage cannot occur.

Die Erfindung hat die Aufgabe, die Korrosion an Kraftfahrzeugen zu hindern. Diese Aufgabe wird erfindungsmäßig durch den Kathodeneffekt elektrisch gelöst.The invention has the task of preventing corrosion on motor vehicles prevent. According to the invention, this task becomes electrical due to the cathode effect solved.

Dieser Schutz ist leichter auszuführen und zu prüfen, als andere Maßnahmen. Die mit der Erfindung erzielten Vorteile bestehen darin, daß der (,chutz wegen seiner elektrischen Eigenschaften am gesamten Fahrzeug wirkt.This protection is easier to implement and test than other measures. The advantages achieved with the invention are that the (, protection because of its electrical properties on the entire vehicle.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung Korrosionsschutz-Schaltung dargestellt und nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing, corrosion protection circuit shown and described in more detail below.

Für den Korrosionsschutz wird der kathodische Effekt verwendet, der die Korrosionsreaktionen hindert. Die dazu notwendigen Potential- und Stromwerte sind nach eigenen Erkenntnissen und Literatur gewählt, (Handbuch des kathodischen Korrosionsschutzes, Baeckmann/Schwenk, Pourbaix Diagramm, S. 28) und bestätigt mit Prüfungen an einem PKW.The cathodic effect is used for corrosion protection which prevents corrosion reactions. The necessary potential and current values are chosen according to our own knowledge and literature, (manual of the cathodic Corrosion protection, Baeckmann / Schwenk, Pourbaix diagram, p. 28) and confirmed with Tests on a car.

Die Ausführung des Schutzes ist aus der Zeichnung ersichtlich.The design of the protection can be seen in the drawing.

Die Elemente sind für KW's mit einer 12 V-Spannung angegeben.The elements are specified for KWs with a 12 V voltage.

Die Fahrzeugbatterie 1 (12 V) ist mit minuspol an die Karosserie und mit Pluspol an die t;chutzanlage angeschlossen. Die Spannungsdifferenz zwische-n Batterie 1 und Zenerdiode 4 (10V) erzeugt den notwendigen Strom und Yoteiitial. Der Stromkreis ist über Sicherung 2, Widerstand 3 (170 KOhm), Zenerdiode 4, Drucktaste 6 über die Leistung 7 durch den Wagen mit der Batterie 1 geschlossen. Bettung 7 sichert dabei den Strom und das Potential am Wagen.The vehicle battery 1 (12 V) is connected to the body and with the negative pole connected to the protection system with positive pole. The voltage difference between-n Battery 1 and Zener diode 4 (10V) generate the necessary current and potential. The circuit is via fuse 2, resistor 3 (170 KOhm), Zener diode 4, push button 6 on the power 7 closed by the car with the battery 1. Bedding 7 secures the electricity and the potential on the car.

Der Strom und damit die Schaltung werden mit dem Meßgerät 5 (0-30 µA) bei Betätigen der Drucktaste 6 kontrolliert.The current and thus the circuit are measured with the measuring device 5 (0-30 µA) by pressing push button 6.
