Description

Die "Erfindung- bezieht sich auf- ein.-Luftfeder=-element, das sich durch Einfachheit und Zwecli#-. mäßigkeit auszeichnet. Es ist bekannt, Luftfedern mit Verstärkungen zu versehen,-die innen,-außen-oder innerhalb des umschließenden, Körpers .liegen.. Auch verwendet man bereits am äußeren Umfang arigeördnete Halterungen, die gleichzeitig ?,1s F_ ührung dienen.The "invention relates to a. -Air spring = element that through simplicity and purpose # -. moderation. It is known air springs to provide reinforcements, -the inside, -outside or inside of the enclosing, Body .lie .. Also one uses already on the outer circumference arigeördnete brackets, which serve at the same time?, 1s leadership.

Das Fesen der Erfindung besteht darin, daß dis Wandstärke des für die Luftfedern verwendeten Gummis oder Kunststoffs unter Verzicht auf Wülste, Verstärkungen u. dgl. verschieden bemessen ist, um auf diese Weise bei der durch die Zusammenpressung gegebenen fortschreitenden Erhöhung .des Luftdrucks den nicht ürifierstützten Teilen des Elements eine genügende-Widerstandsfähigkeit gegen Zerstörung zugeben.The Fesen of the invention is that the wall thickness of the for the air springs used rubber or plastic without bulges or reinforcements and the like. Is differently dimensioned in order in this way by the compression given a progressive increase in air pressure in the non-urifier-supported parts of the element to admit sufficient resistance to destruction.

In der Zeichnung ist der Gegenstand der @Erfindung in zwei Abbildungen im- Längsschnitt' dargestellt.In the drawing, the subject of the invention is in two figures shown in the longitudinal section.

Abb. i zeigt ein Luftfederelement im unberaäteten und Abb. 2 im belasteten Zustand.Fig. I shows an air spring element in the unshown and Fig. 2 in the loaded one State.

Bei Belastung einer Luftfeder entsteht in ihr ein Luftdruck p. Der Krümmungsradius hat an . der Anlagestelle des belasteten Organs-a den Wert_R, Während die Wandstärke an dieser Stelle s mm beträgt. Bei einer zulässigen Zugbeanspruchung des Güinmis ergibt sich der zulässige Luftdruck p annähernd zu Für en Fall, daß 1Z konstant oder nahezu konstant ist, ergibt sich, daß die Wandstärke proportional dem Druck p wird. Da aber mit zunehmender Einfederung der Druck p wächst, muß somit auch die Wandstärke s für diejenigen Teile -der Luftfelder wachsen, welche ohne Unterstützung seitens der Teile a dem Luftdruck standhalten müssen, so daß also die Wandstärke der Luftfeder, die der Achse b-- am -nächsten liegt, verhältnismäßig gering auf Zug beansprucht wird, mit zunehmender Federung aber die Gummi- oder Kunststoffteile, welche in größerer Entfernung von der Achse b-b liegen, je,nach: ihrer Entfernung von dieser Achse stärker ausgeführt werden müssen.When an air spring is loaded, an air pressure p arises in it. The radius of curvature has on. the contact point of the loaded organ-a value_R, while the wall thickness at this point is s mm. With a permissible tensile load on the Güinmi, the permissible air pressure p is approximately equal to In the event that 1Z is constant or almost constant, the result is that the wall thickness is proportional to the pressure p. Since, however, the pressure p increases with increasing deflection, the wall thickness s for those parts of the air fields which have to withstand the air pressure without support from the part a, so that the wall thickness of the air spring that of the axis b-- The closest is, is relatively little stressed on train, with increasing suspension but the rubber or plastic parts, which are at a greater distance from the axis bb, depending on: their distance from this axis must be made stronger.
