Description
Regelbares Röhrenmanometer für die Messung des Druckes in Luftreifen von Kraftfahrzeugen Manometer, die auf verschiedene Druckhöhen einstellbar sind, sind bekannt. Die Mittel zur diesbezüglichen Beeinflussung der Federröhre bestehen in einem von außen einstellbaren Widerlager, mittels dessen durch äußeren Druck auf die Federröhre der wirksame Hebelarm derselben bzw. deren Ansprechkraft geändert werden kann.Adjustable tube manometer for measuring the pressure in pneumatic tires of motor vehicles pressure gauges that can be adjusted to different pressure levels, are known. The means for influencing the spring tube in this regard exist in an externally adjustable abutment, by means of which by external pressure on the spring tube of the effective lever arm of the same or their response force changed can be.
Sämtliche derartig regelbare Manometer sind nun aber so beschaffen, daß der Wirkungskreis des einstellbaren Widerlagers sich nur auf einen Punkt der Federröhre beschränkt, was bei Änderungen der Belastung der Fahrzeuge nicht wünschenswert ist.All such controllable pressure gauges are now designed in such a way that that the sphere of action of the adjustable abutment is only on one point of the Spring tube limited, which is undesirable when the load on the vehicle changes is.
Anders liegen die Verhältnisse beim Röhrenmanometer, welches den Gegenstand der Erfindung bildet. Dasselbe kennzeichnet sich dadurch, daß das einstellbare Widerlager für die Veränderung des wirksamen Hebelarmes der Federröhre von zwei Gleitschenkeln gebildet wird, die wechselweise an die Federröhre auf verschiedenen Hebelarmen derselben anstellbar sind. Man hat es hierdurch in der Hand, von einer Stelle aus die Federröhre im wirksamen Hebelarm auf einen höheren und niederen Druck entsprechend wechselnden Belastungen des Fahrzeugs einzustellen.The situation is different with the tube manometer, which is the object of the invention. The same is characterized by the fact that the adjustable abutment for changing the effective lever arm of the spring tube of two sliding legs is formed, which is alternately attached to the spring tube on different lever arms of the same are employable. You have it in your hand, the spring tube from one point accordingly changing in the effective lever arm to a higher and lower pressure Adjust loads on the vehicle.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes.The drawing shows an embodiment of the subject matter of the invention.
a ist das Manometergehäuse, in welchem die bekannte Federröhre b bei c am Manometeranschlußstutzen d befestigt ist, während ihr anderes freies Ende mit dem Zeiger e in Verbindung steht. Das von außen einstellbare Widerlager wird durch zwei radial geführte Gleitschenkel p, p1 gebildet, die mit Druckstollen q versehen und durch Drehen eines gemeinsamen Exzenters r abwechselnd so eingestellt werden können, daß die Federröhre b sich bei der gewollten Druckhöhe auf verschiedenen Hebelarmen abstützt.a is the manometer housing in which the well-known spring tube b at c is attached to the pressure gauge connection piece d, while its other free end with the pointer e is connected. The externally adjustable abutment is through formed two radially guided sliding legs p, p1, which are provided with pressure studs q and by rotating a common eccentric r can be set alternately can that the spring tube b at the desired pressure level on different Supports lever arms.
Der Anschlußstutzen d des Manometers weist ein Linksgewinde lt auf, in welchem eine Überwurfmutter i sitzt, welche zu der üblichen Luftschlauchventilschraube j paßt.The connection piece d of the pressure gauge has a left-hand thread lt, in which a union nut i sits, which connects to the usual air hose valve screw j fits.
Das Manometer besitzt zwei Meßskalen, nämlich eine obere, die bis zum Druckmaximum von g Atm. reicht, und eine zweite untere, die bis zu io Atm. anzeigt.The manometer has two measuring scales, namely an upper one that goes up to to the pressure maximum of g Atm. enough, and a second lower one that goes up to io Atm. indicates.
je nach der Belastung des Fahrzeugs wird der Exzenter r mittels seines Griffhebels s mehr oder weniger stark gedreht, um im einen Falle, nämlich bei höherer Belastung, den Gleitschenkel p an die Federröhre auf einem größeren wirksamen Hebelarm derselben anzustellen, so daß die Federröhre einen größeren Aktionsbereich erhält, oder im anderen Falle, wenn man es mit einer geringeren Belastung zu tun hat, den Gleitschenkel p1 an die Federröhre auf einem geringeren wirksamen Hebelarm anzustellen, so daß der Aktionsbereich des Zeigers geringer wird.depending on the load on the vehicle, the eccentric r is by means of its Handle lever s rotated more or less strongly to in one case, namely at higher Load, the sliding leg p to the spring tube on a larger effective lever arm to set the same so that the spring tube has a larger action area, or in the other case, when one is dealing with a lower burden, the Set sliding leg p1 to the spring tube on a lower effective lever arm, so that the range of action of the pointer becomes smaller.
Die Winkelausschläge des Exzenters r für die verschiedenen Druckhöhen werden bei der Herstellung des Manometers ausprobiert, gerichtet, geeicht und angezeichnet, so daß der Käufer ohne weiteres unterrichtet ist. Der Wagenführer weiß, daß die Luftschläuche seines Wagens nur eine Last ertragen, die einem bestimmten Höchstdruck entspricht. Er wird dann im Bedarfsfalle das auf dieses Druckmaximum eingestellte Manometer an der Luftschlauchventilschraube j befestigen. Der hierbei vorhandene Raum in der Nähe derselben ist meist sehr beschränkt, weshalb die üblichen Manometer schwer anzubringen sind, während die mit Links- und Rechtsgewinde versehene Überwurfmutter i gestattet, ohne irgendwelche Bewegung des Manometers dieses auf der Ventilschraube j zu befestigen, weil während des Aufschraubens der Überwurfmutter i auf die Schraube j das Manometer angezogen wird. Ist dies geschehen, dann kann die Luf'tbeschickungsleitung angeschlossen und der Luftschlauch mit Druckluft gespeist werden.The angular deflections of the eccentric r for the different pressure levels are tried out, straightened, calibrated and marked during the manufacture of the manometer, so that the buyer is immediately informed. The driver knows that the air hoses in his car can only bear a load that corresponds to a certain maximum pressure. If necessary, he will then attach the manometer set to this pressure maximum to the air hose valve screw j. The space available in the vicinity of the same is usually very limited, which is why the usual pressure gauges are difficult to attach, while the left and right-hand threaded union nut i allows the pressure gauge to be fastened to the valve screw j without any movement of the pressure gauge, because during screwing the union nut i is tightened on the screw j the pressure gauge. Once this has been done, the air supply line can be connected and the air hose can be fed with compressed air.
