Description

Vorrichtung zum Anzeigen des Entweichens von Luft aus einem Luftreifen von Kraftfahrzeugen Es ist bekannt, wie unangenehm es sein und welche bösen Folgen es haben kann, wenn bei Beschädigung eines Luftreifens an Kraftfahrzeugen der Austritt von Luft nicht sofort bemerkt wird.Device for indicating the escape of air from a pneumatic tire of motor vehicles It is well known how uncomfortable it can be and what nasty consequences it can have if the leak occurs when a pneumatic tire on a motor vehicle is damaged is not immediately noticed by air.

Durch nachstehende Erfindung wird diesem Übelstande abgeholfen.This drawback is remedied by the following invention.

Die Erfindung betrifft eire Vorrichtung zum Anzeigen des Entweichens von Luft aus Luftreifen von Kraftfahrzeugen mit einem an der Fahrzeugachse befestigten Arm, an dessen unterem Ende eine elektrische Kontaktvorrichtung mit einem unter Federdruck stehenden, in einer Querebene des Fahrzeugs schwingbaren Arm angeordnet ist, der in der Nähe der tiefsten Stelle des Radkranzes eine Rolle trägt, wobei sich die Vorrichtung dem bereits Bekannten gegenüber dadurch kennzeichnet, daß die Rolle in der tiefsten Lage des Schwingarmes unmittelbar neben der Felge und über dem Reifen sich befindet, mit dem sie beim Entweichen von Luft in Berührung kommt.The invention relates to a device for indicating the escape from air from pneumatic tires of motor vehicles with one attached to the vehicle axle Arm, at the lower end of which has an electrical contact device with an under Spring pressure standing, arranged in a transverse plane of the vehicle swingable arm is, which carries a role near the deepest point of the wheel rim, wherein the device is characterized by the fact that the already known Roll in the lowest position of the swing arm immediately next to the rim and above the tire with which it comes into contact when air escapes.

Auf der Zeichnung ist die Erfindung dargestellt, und zwar zeigen Abb. = die Vorrichtung in Vorderansicht, Abb. 2 die Vorrichtung nach Abnahme ihres Schaltdosendeckels in Vorderansicht, Abb. 3 die an einer Radachse angebrachte Vorrichtung in Vorderansicht und Abb. q. die geöffnete Schaltdose in Draufsicht. Die Vorrichtung besteht aus einem rechtwinklig gebogenen Rohr a, das in dem Rohrstück b verschieb- und drehbar lagert und dort durch die Schraube c gesichert werden kann, und das mittels zweier Laschen d, von denen die eine festsitzend an dem Rohrende b angebracht ist, auf der Radachse e befestigt wird. In dem Rohr a ist nach unten ein zweites Rohr f verschieb- und drehbar gelagert, das dort in der jeweiligen Stellung durch eine an dem Rohr a befindliche Stellschraube gesichert werden kann. Am unteren Ende ist an dem Rohr f eine Schaltdose h befestigt, die einen beweglichen, unter dem Druck einer Feder i stehenden Schaltarm k besitzt, dessen Bewegung nach unten zweckmäßig durch einen Anschlag = begrenzt wird und der an seinem freien Ende mit einem Laufrade m versehen ist, das unten dicht über dem Luftreifen n ruht und durch diesen beim Austritt von Luft gehoben wird. Hierdurch wird gleichzeitig .ein damit verbundenes Schleifstück s nach rechts gedreht und mit einer Kontaktzunge P in Berührung gebracht, so daß dadurch der Kontakt geschlossen ist. Die Vorrichtung ist mit einer elektrischen Leitung o versehen, die zu einer an dem Führersitz angebrachten Anzeigevorrichtung führt, die bei Kontaktschluß bewegt wird und dann dadurch dem Führer anzeigt, daß an den Reifen Luft austritt.The invention is shown in the drawing, namely Fig. = The device in a front view, Fig. 2 the device after removing its switch box cover in a front view, Fig. 3 the device attached to a wheel axle in a front view and Fig. Q. the opened switch box in plan view. The device consists of a tube a bent at right angles, which is slidably and rotatably supported in the tube section b and can be secured there by the screw c, and which is mounted by means of two tabs d, one of which is firmly attached to the tube end b the wheel axle e is attached. In the tube a , a second tube f is mounted displaceably and rotatably downwards, which can be secured there in the respective position by an adjusting screw located on the tube a. At the lower end of the tube f, a switch box h is attached, which has a movable switch arm k under the pressure of a spring i, the downward movement of which is expediently limited by a stop = and which is provided with an impeller m at its free end is that rests at the bottom just above the pneumatic tire n and is lifted by this when air escapes. As a result, a connected contact strip s is simultaneously rotated to the right and brought into contact with a contact tongue P so that the contact is thereby closed. The device is provided with an electrical line o which leads to a display device attached to the driver's seat, which is moved when the contact is closed and then thereby indicates to the driver that air is escaping from the tires.

Zweckmäßig wird neben jedem Luftreifen eine solche Anzeigevorrichtung angebracht; jedoch kann die Vorrichtung auch mit mehreren Schaltarmen k versehen sein, die nach verschiedenen Seiten ausliegen und dann gleichzeitig zweiLuftreifen auf Luftaustritt hin prüfen.Such a display device is expedient next to each pneumatic tire appropriate; however, the device can also be provided with a plurality of switching arms k that are laid out on different sides and then two pneumatic tires at the same time check for air leakage.
