Eine
pneumatische Luftfeder-Dämpfereinheit
der eingangs genannten Art ist aus der
Aufgabe der Erfindung ist es, eine pneumatische Luftfeder-Dämpfereinheit zu schaffen, welche ein selbsttätiges und wegabhängiges Öffnen und Schließen einer Drossel zwischen einer Luftfeder und einem Zusatzwirkraum gestattet.task The invention is a pneumatic air spring damper unit to create an automatic one and path-dependent opening and closing of a Throttle between an air spring and an additional reaction room allowed.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. In der Luftfeder-Dämpfereinheit ist die erste Öffnung selbsttätig durch den Einfedervorgang des Kolbens und der Kolbenstange in das Zylindergehäuse verschließbar. In voll ausgefedertem Zustand der Luftfeder-Dämpfeinheit ist die erste Öffnung vollständig geöffnet. Die erste Öffnung ist axialer Richtung so in der Kolbenstange angeordnet, dass, wenn die Luftfeder-Dämpfeinheit in axialer Richtung weiter zusammengedrückt wird und einfedert, die erste Öffnung ab einem bestimmten und vorgegebenen Einfederweg geschlossen wird, so dass durch die erste Öffnung kein Luftaustausch mehr zwischen dem ersten und dem zweiten Wirkraum stattfinden kann, wodurch der dritte Wirkraum als härtere, zusätzliche Feder verwendbar ist. Die Dämpfung der Luftfeder-Dämpfeinheit nimmt durch die Volumenverkleinerung des ersten Wirkraums infolge der geschlossenen ersten Öffnung zu. Beide Effekte, die härtere Feder und die höhere Dämpfung, erhöhen die Gesamtsteifigkeit der Luftfeder-Dämpfeinheit und damit die gewünschte Progression dieser bei größerer Einfederung, insbesondere kurz vor oder am Endanschlag.These The object is achieved by the Characteristics of claim 1 solved. In the air spring damper unit is the first opening automatically through the spring deflection of the piston and the piston rod in the cylinder housing closed. In full Sprung state of the air spring damper unit, the first opening is fully open. The first opening is axial direction so arranged in the piston rod that when the air spring damping unit is further compressed in the axial direction and springs, the first opening is closed from a certain and predetermined compression travel, so that through the first opening no air exchange between the first and the second active space can take place, making the third effective space as harder, additional Spring is usable. The damping the air spring damping unit takes by the volume reduction of the first effective space as a result of closed first opening. Both effects, the harder Spring and the higher damping, increase the overall stiffness of the air spring damping unit and thus the desired progression this with greater deflection, especially shortly before or at the end stop.
Der Vorteil der Erfindung ist darin zu sehen, dass durch das Verschließen der ersten Öffnung ein progressives Federungsverhalten der Luftfeder-Dämpfeinheit insbesondere nur dann erzeugt wird, wenn es bei großen Einfederwegen, insbesondere kurz vor dem Endanschlag, benötigt wird und sinnvoll ist. Gleichzeitig ein Durchschlagen der Luftfeder-Dämpfeinheit insbesondere bei extremen Fahrmanövern verhindert. Ein weiterer Vorteil der Erfindung ist darin zu sehen, dass im normalen Einfederungszustand der Luftfeder- Dämpfeinheit die erste Öffnung geöffnet ist und die Luftfeder-Dämpfeinheit ein normales Federungsverhalten mit einem hohen Komfort zeigt.Of the Advantage of the invention is the fact that by closing the first opening a progressive suspension behavior of the air spring damping unit especially only when it is at large compression distances, especially shortly before the end stop, is needed and makes sense. At the same time a penetration of the air spring damping unit especially with extreme driving maneuvers prevented. Another Advantage of the invention is the fact that in the normal compression state the air spring damping unit the first opening open is and the air spring damping unit normal suspension behavior with a high comfort shows.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 2 ist vorgesehen, dass die erste Öffnung als Bohrung ausgeführt ist. Der Vorteil dieser Weiterbildung der Erfindung ist darin zu sehen, dass eine Bohrung sehr einfach und kostengünstig herstellbar ist.According to one Development of the invention according to claim 2 is provided that the first opening executed as a bore is. The advantage of this development of the invention is to see that a bore is very easy and inexpensive to produce is.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 3 ist vorgesehen, dass eine Dichtung zur Abdichtung der ersten Öffnung in dem Zylindergehäuse angeordnet ist. Der Vorteil dieser Weiterbildung besteht darin, dass keine zusätzlichen Bauteile für die Abdichtung der ersten Öffnung und oder des Zylindergehäuses zur Kolbenstange zwischen dem zweiten und dem dritten Wirkraum benötigt werden, was Kosten einspart.According to one Development of the invention according to claim 3 is provided that a seal for sealing the first opening in the cylinder housing arranged is. The advantage of this development is that no additional Components for the sealing of the first opening and or the cylinder housing needed to the piston rod between the second and the third effective space, what Saves costs.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 4 ist vorgesehen, dass das Zylindergehäuse einen Kragen aufweist, der in den dritten Wirkraum hineinragt. Erfindungsgemäß weist der Kragen eine axiale Länge auf, um die erste Öffnung abzudichten und ggf. die Führung der Kolbenstange zu verbessern. Der Vorteil dieser Weiterbildung besteht darin, dass die Abdichtung mit einer einfachen konstruktiven Erweiterung des Zylindergehäuses und ohne zusätzliche Bauteile erfolgen kann, was Kosten einspart.According to one embodiment of the invention according to claim 4, it is provided that the cylinder housing has a collar which projects into the third active space. According to the invention, the collar has an axial length in order to seal the first opening and possibly the guidance of the piston rod to improve. The advantage of this development is that the seal can be done with a simple structural extension of the cylinder housing and without additional components, which saves costs.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 5 ist vorgesehen, dass der Federbalg als Rollbalg ausgeführt ist. Der Vorteil dieser Weiterbildung ist darin zu sehen, dass ein Rollbalg große Einfederwege zulässt und ein sehr komfortables Federverhalten erzeugt.According to one Development of the invention according to claim 5 is provided that the bellows is designed as a rolling bellows. The advantage of this Training can be seen in that a rolling bellows large compression travel allows and creates a very comfortable spring behavior.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 6 ist vorgesehen, dass das zweite Ende des Rollbalges an einem an der Kolbenstange angeordneten Abrollkolben befestigt ist. Die Verwendung eines Abrollkolbens ermöglicht den Einsatz von beliebigen Abrollgeometrien, was den Komfort und das Federungsverhalten der Luftfeder-Dämpfereinheit positiv beeinflusst.According to one Development of the invention according to claim 6 is provided that the second end of the rolling bellows on a arranged on the piston rod Rolling piston is attached. The use of a rolling piston allows the Use of any rolling geometries, what the comfort and the Suspension behavior of the air spring damper unit positively influenced.
Gemäß einer Weiterbildung der Erfindung nach Anspruch 7 ist vorgesehen, dass der Abrollkolben innen hohl ausgeführt ist, so dass der Kragen des Zylindergehäuses in diesen Hohlraum eintauchen kann. Der Vorteil dieser Weiterbildung der Erfindung besteht in der sehr kompakten Bauweise, welche den Einsatz der Luftfeder-Dämpfereinheit in sehr kleinen Bauräumen gestattet. Gleichzeitig kann der innere Hohlraum des Abrollkolben als zusätzlicher Wirkraum der Luftfeder genutzt werden, was den Komfort und das Federungsverhalten dieser positiv beeinflusst.According to one Development of the invention according to claim 7 is provided that the rolling piston is hollow inside, so that the collar of the cylinder housing can dip into this cavity. The advantage of this development The invention consists in the very compact design, which the Use of the air spring damper unit in very small installation spaces allowed. At the same time, the inner cavity of the rolling piston as an additional effective space the air spring are used, what the comfort and suspension behavior this influenced positively.
