Description
Luftfederung, insbesondere für Kraftfahrzeuge Die Erfindung bezieht sich auf Luftfederungen, in denen gegen Ende des Federungshubes durch einen in einen Hilfszylinder eintretenden Hilfskolben der Druckraum -les Führungszylinders in zwei Teildruckräume unterteilt wird.Air suspension, in particular for motor vehicles The invention relates on air suspensions, in which towards the end of the suspension stroke through one into one Auxiliary cylinder entering auxiliary piston of the pressure chamber -les guide cylinder in two Partial pressure spaces is divided.
Nach der Erfindung ist der Hilfskolben von einem Kanal durchsetzt, in dem ein Rückschlagventil angeordnet ist, das, sobald im Hauptzylinder der Druck denjenigen im Hilfszylinder Übersteigt, der Druckluft den Eintritt in den Hilfszylinder gestattet, das aber schließt, wenn umgekehrt im Hilfszylinder ein höherer Druck herrscht als im Hauptzylinder und dann eine Rückströmung der Luft verhindert.According to the invention, the auxiliary piston is penetrated by a channel, in which a check valve is arranged, which, as soon as the pressure in the master cylinder Exceeds that in the auxiliary cylinder, the compressed air entering the auxiliary cylinder permitted, but this closes when, conversely, a higher pressure in the auxiliary cylinder prevails than in the main cylinder and then prevents the air from flowing back.
Infolge dieser Anordnung wird beim Füllen des Hauptfederungszylinders der Hilfskolben auf seinen beiden Kolbenflächen vom gleichen Druck belastet und die auf Verschiebung des Hauptkolbens wirkende Kraft um die Belastung der dem Innenraum des Hilfszylinders zugewendeten Flächen des Hilfskolbens vergrößert.As a result of this arrangement, when filling the main suspension cylinder the auxiliary piston is loaded by the same pressure on its two piston surfaces and the force acting on the displacement of the main piston by the load on the interior of the auxiliary cylinder facing surfaces of the auxiliary piston enlarged.
Das Rückschlagventil könnte statt im Kolben auch in der Wand des Hilfszylinders angeordnet sein.The check valve could also be in the wall of the auxiliary cylinder instead of in the piston be arranged.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Längsschnitt dargestellt.In the accompanying drawing is an exemplary embodiment of the subject matter of the invention shown in longitudinal section.
Der Kolben ist in der Endstellung gezeichnet, bei welcher der Hilfskolben im Hilfszylinder liegt. Die entgegengesetzte Endlage ist strichpunktiert angedeutet.The piston is drawn in the end position in which the auxiliary piston lies in the auxiliary cylinder. The opposite end position is indicated by dash-dotted lines.
Der Hilfszylinder a ist am Boden des Hauptzylinders b angeordnet, Hilfskolben c und Hauptkolben d werden durch die gleiche Kolbenstange bewegt. Der Hilfskolben c besteht beispielsweise aus zwei Platten c" c., die zwischen sich den Dichtungsring f fesiklemmen.The auxiliary cylinder a is arranged at the bottom of the master cylinder b, Auxiliary piston c and main piston d are moved by the same piston rod. Of the Auxiliary piston c consists, for example, of two plates c "c., The between them Sealing ring f fesiklemme.
Die Schraube g, die die obere Platte mit der unteren verbindet, ist mit einer Längsbohrung h versehen, ebenso ist im Schraubenzapfen i, der die untere Platte mit der Kolbenstange verbindet, eine Längsbohrung h vorgesehen. Die Bohrungen h und % finden in der Kolbenstange eine Fortsetzung in Gestalt der Bohrung L, die durch den Kanal in mit dein Innenraum des Hauptzylinders in Verbindung steht.The screw g, which connects the upper plate to the lower one, is provided with a longitudinal bore h, and a longitudinal bore h is also provided in the screw pin i, which connects the lower plate to the piston rod. The holes h and% refer to the piston rod a continuation in the shape of the bore L, which is through the channel in with your interior of the master cylinder in communication.
Bei ia ist das als Kugelventil ausgebildete Rückschlagventil angeordnet. Dieses Ventil öffnet sich, sobald im Hauptzylinder, also auch in den Kanälen h, h,1, der Druck im Begriff ist, denjenigen im Hilfszylinder zu übersteigen. Von da an und während der nun einsetzenden Verschiebung der Kolben tritt ein Druckausgleich in beiden Zylinderräumen ein.In the case of ia, the check valve designed as a ball valve is arranged. This valve opens as soon as the pressure in the main cylinder, i.e. also in the channels h, h, 1, is about to exceed that in the auxiliary cylinder. From then on and during the displacement of the pistons that now begins, pressure equalization occurs in both cylinder chambers.
