Description

Gegenstand der Erfindung ist eine Vorrichtung, die es gestattet, mittels des Luftdruckes im Reifen eines Fahrzeuges den erforderlichen Reifendruck selbsttätig aufrechtzuerhalten.The invention relates to a device that allows by means of the air pressure in the tires of a vehicle automatically sets the required tire pressure maintain.

Bekanntlich muß in einer Fahrzeugbereifung in Zeitabständen der Luftdruck ergänzt werden. Es muß aber auch der beim Fahren mit hohen Geschwindigkeiten und großen Belastungen entstehende, über das zulässige Maß hinausgehende Überdruckentfernt werden. Entsprechend dem Vorschlag der Erfindung kann man nun den Reifendruck dazu benutzen, mittels einer auf den gewünschten Reifendruck einstellbaren Meß- und Arbeitsdose a den Reifendruck konstant zu halten. Zu diesem Zweck ist mit der Meß- und Arbeitsdose ein Gestänge b verbunden, das bei eintretendem Überdruck ein Luftauslaßventil c öffnet und bei Minderdruck durch einen elektrischen Kontakt d einen Stromkreis schließt, der mittels eines Elektromagneten e eine Luftpumpe f einkuppelt. Die Pumpe, die an dem Radkörper angeordnet ist, tritt also nur in Tätigkeit bei Minderdruck und wird von der Meß- und Arbeitsdose durch Öffnen des gleichen Kontaktes wieder abgeschaltet. Durch die Benutzung eines elektrischen Kontaktes und eines elektrischen Kupplungsmagneten ist es möglich, daß die mit dem Radkörper umlaufende Meß- und Arbeitsdose den nicht umlaufenden Kupplungsmagneten steuert, der durch Verschieben seiner Schaltnocken g die mit dem Radkörper umlaufende Luftpumpe in Tätigkeit setzt.As is well known, the air pressure must in a vehicle tire at time intervals can be added. But it must also be used when driving at high speeds and Removes excess pressure that occurs under high loads and exceeds the permissible level will. According to the proposal of the invention, you can now add the tire pressure use, by means of a measuring and working cell that can be adjusted to the desired tire pressure a to keep the tire pressure constant. For this purpose is with the measuring and work box a linkage b connected which, when excess pressure occurs, an air outlet valve c opens and when there is insufficient pressure, an electrical contact d closes a circuit, which engages an air pump f by means of an electromagnet e. The pump that is arranged on the wheel body, so only comes into operation at low pressure and is switched off again by the measuring and work socket by opening the same contact. By using an electrical contact and an electrical coupling magnet it is possible that the measuring and working cell rotating with the wheel body does not The rotating clutch magnet controls by moving its switching cams g activates the air pump rotating with the wheel center.
