Description

359758359758

Die Erfindung hat eine elektrische Anzeige-Errichtung zum Gegenstande, durch welche :r Drucknachlaß in Luftreifen von Kraft-Jirzeugen zur Kenntnis des Fahrers gebracht ird. Die Vorrichtung beruht auf dem beinnten Grundsatz, daß zwei Pole infolge der arken Abflachung des Luftreifens bei Druckichlaß in Verbindung gebracht werden. Xeu t es, diese beiden Pole in das Innere des uftreifens zu verlegen, wo sie durch den iruck der Luft in Abstand voneinander gealten werden.The invention has an electrical display device on the subject by which: r pressure relief in pneumatic tires of Kraft-Jirzeugen brought to the knowledge of the driver. The device is based on the bone Principle that two poles as a result of the sharp flattening of the tire when pressure is released be associated. It is necessary to move these two poles into the interior of the tire, where they pass through the The air must be aged at a distance from each other.

Da einer der Pole von einem schmiegimen Körper gebildet werden muß, der sich α die Innenfläche des Luftschlauches anlegt, 3 ist es zweckmäßig, daß hierzu eine Kupferaze genommen wird, die mit dem Schlauch erklebt wird, während der andere Pol vom rentilkörper getragen wird und aus einer rei endenden Schraubenfeder besteht.Since one of the poles of a schmiegimen body must be formed of α, the inner surface of the air tube applies, 3, it is desirable that this is erklebt with the hose a Kupferaze is taken, while the other pole of r alv e body is supported and consists of a rei ending coil spring.

In der Zeichnung ist die Erfindung in einem tusführungsbeispiel dargestellt.In the drawing, the invention is shown in an exemplary embodiment.

Das Innere des Luftschlauches d ist mit iner bandartig gestalteten Kupfergaze e verehen, von der eine Leitung/ zur Nabe des tades führt. Diese Leitung ist gegen den Rentilkörper α isoliert. Eine zweite Leitung Z1 st mit dem Ventilkörper α in elektrische Veriindung gebracht. Auf dem Vehtilkörper ist die Schraubenfeder b .mit einem Kontaktstück c stromleitend verbunden und ragt in das Innere des Luftschlauches hinein. Die Leitungen /, Z1 führen zu Schleifringkontakten der Nabe und von diesen über eine Stromquelle hinweg zu einer Anzeigevorrichtung zum Führersitz.The inside of the air hose d is decorated with a ribbon-like copper gauze e from which a line / leads to the hub of the tades. This line is isolated from the rentile body α. A second line Z 1 st brought into electrical connection with the valve body α. On the valve body, the helical spring b is connected to a contact piece c to conduct electricity and protrudes into the interior of the air hose. The lines /, Z 1 lead to slip ring contacts of the hub and from these via a power source to a display device in the driver's seat.

Läßt der Druck im Schlauch über ein ge-Avisses Maß nach, so berühren sich die Pole c und e, so daß die Anzeigevorrichtung in Tätigkeit tritt.If the pressure in the hose decreases by a certain amount, the poles c and e touch each other, so that the display device comes into operation.
