Abstract

The tyre pressure monitor system consists of a regulator valve (3) and a reserve air container (2) fitted in or on the tyre rim. The reserve air container has a higher air pressure than the tyre and permits air to flow into the tyre via the preset regulator valve when the tyre pressure falls below the required value during a journey. Should the tyre pressure exceed the permitted pressure, the regulator allows the excess air to escape to atmosphere, so that the tyre shows correct pressure at all times. The reserve air container is fitted to each wheel and pressurised at a service station by means of its one way valve (1). A visual or acoustic signal is given to the driver when the reserve tank pressure becomes less than that of the tyre pressure.

Description

Kraf-tfahrzeugreifen mit Druckwächter Die Erfindung betrifft einen Kraftfahrzeugreifen, der mit einem Druckwächter ausgestattet ist, um stets den richtigen LuEtdru-ck im Reifen einzuhalten.Power vehicle tires with pressure monitor The invention relates to a Motor vehicle tire that is equipped with a pressure monitor to always ensure the correct one Maintain air pressure in the tire.

Bisher wird der Luftdruck in der Reifenluftkammer von einer Füllstation geliefert. Die richtige Druckeinstellung an jedem Reifen muß häufig und genau mit einem Manometer geprüft und gegebenenfalls korrigiert werden.So far, the air pressure in the tire air chamber is from a filling station delivered. The correct pressure setting on each tire must be carried out frequently and precisely checked with a manometer and corrected if necessary.

Dennoch kann nicht verhindert werden, daß während der Fahrt oder nach einer gewissen Zeit der Luftdruck im Reifen sinkt oder steigt.However, it cannot be prevented while driving or after the air pressure in the tire drops or rises over a period of time.

Ziel der Erfindung ist, diese Mängel zu beseitigen und die häufigen und genauen Prüfungen des Reifenluftdrucks wegfallen zu lassen.The aim of the invention is to eliminate these shortcomings and the common ones and to omit precise tests of the tire air pressure.

Die Erfindung ist anhand der Zeichnung schematisch darges-tellt. Der Druckwächter, bestehend hauptsächlich aus einem Regulierventil 3 und einem Reserveluftbehälter 2, ist in oder an der Felge des Reifens 4 befestigt.The invention is shown schematically with reference to the drawing. Of the Pressure switch, consisting mainly of a regulating valve 3 and a reserve air tank 2, is fastened in or on the rim of the tire 4.

Im Reserveluftbehälter 2 befindet sich Luft unter höherem Druck als im Reifen 4 und dient damit als Luftspeicher.In the reserve air tank 2 there is air at a higher pressure than in the tire 4 and thus serves as an air reservoir.

über das Regulierventil 3, welches auf den gewünschten Druck im Reifen 4 einstellbar ist, kann die Luft in den Reifen 4 während der Fahrt einströmen, wenn der Druck im Reifen 4 zu niedrig ist. Wenn sich der Druck im Reifen 4 unzulässig erhöht, läßt das Regulierventil 3 Luft ins Freie ab. Somit herrscht im Reifen 4 immer der richtige Druck.via the regulating valve 3, which is set to the desired pressure in the tire 4 is adjustable, the air can flow into the tire 4 while driving, if the pressure in tire 4 is too low. If the pressure in the tire 4 is inadmissible increases, the regulating valve 3 releases air into the open. Thus there is 4 in the tire always the right pressure.

Am Reserveluftbehälter 2 befindet sich ein Rückschlagventil t, mit weichem der Reserveluftbeha-tlter 2 aufgefüllt werden kann. Der ReservelufUehälter 2 an jedem Rad wird nur nach in längeren Zeitabständen mit wesentlich höherem Luftdruck als im Reifen gefüllt. Eine Drucküberwachung ist nicht erforderlich, da der ReserveluftbehäIter 2 so bemessen ist, da der max von der Füllstation gelieferte Luftdruck stets aufgenommen werden kann.On the reserve air tank 2 there is a check valve t, with which the reserve air tank 2 can be refilled. The reserve air tank 2 on each wheel is only after at longer time intervals with significantly higher air pressure than filled in the tire. Pressure monitoring is not required as the reserve air tank 2 is dimensioned so that the max air pressure delivered by the filling station is always recorded can be.

Bei Zwillingebereifuung kann für zwei Reifen ein Druckluftwächter eingesetzt werden.In the case of twin tires, a compressed air monitor can be used for two tires can be used.

Beim Absinken des Luftdrucks im reservelufbehälter 2 unter den richtigen Wert des Reifens 4 wird durch akustisches oder optisches Signal am Rad, im Fahrhaus oder an anderer geeigneter Stelle gewarnt.When the air pressure in the reserve air tank 2 drops below the correct The value of the tire 4 is determined by an acoustic or optical signal on the wheel in the cab or warned at another suitable point.

Die Erfindung ist von großer Bedeutung für die Verkehrssicherheit und unterstützt die weltweiten Sicherheitsbestrebungen dadurch, daß. viele auf falschen Reifenluftdruck zurückzuführende Unfälle vermeide werden.The invention is of great importance for road safety and supports global security efforts by. many on wrong Avoid accidents related to tire air pressure.

Die wirtschaftliche Bedeutung der Erfindung liegt darin, daß unnötig hoher Reifenverschleiß durch falschen Ludtdruck vermieden wird und damit Kosten gespart werden.The economic importance of the invention is that it is unnecessary high tire wear due to incorrect pressure is avoided and thus costs be saved.

Weitere Folgen von hohem Reifenverschleiß sind Umweltverschmutzung durch Gummiabrieb, Straßenglätte durch an der Straßenoberfläche haftende Gummiteilchen u. ä.Environmental pollution is another consequence of excessive tire wear through rubber abrasion, slippery roads through rubber particles adhering to the road surface etc.
