Abstract
Description
Die Erfindung betrifft einen pneumatischen Stoßdämpfer, der mit einer ergänzenden oder zusätzlichen Luftkammer ausgestattet ist, die mit der Luftkammer des Zylinderkörpers verbunden ist.The The invention relates to a pneumatic shock absorber with a complementary or additional Air chamber is equipped, which is connected to the air chamber of the cylinder body is.
Im allgemeinen kennzeichnet sich der herkömmliche pneumatische Stoßdämpfer durch ein kompressibles, unter hohem Druck stehendes Gas anstelle herkömmlicher Federkörper, wobei seine verlängerbare Hülse unter Spannung dieselbe Flexibilität bietet. Es läßt sich jedoch keine kontinuierliche Kompression erreichen, wenn Gas in einem einzigen umschlossenen Raum bis zu einem gewissen Grad komprimiert wird, nämlich einem Wendepunkt der im hinteren Teil der Kompressionskurve sichtbar wird, von dem an eine starke Erhöhung der Kompressionskraft für die Kompressionsbewegung erforderlich wird. Daher entsprechen die herkömmlichen pneumatischen Stoßdämpfer aufgrund ihres sehr beschränkten Bereichs effektiver Bewegung nicht den gestellten Anforderungen. Außerdem ist der flexible Stoßwiderstand aufgrund der sehr großen Federkraft des komprimierten Gases sehr gering, was zu einer Minderung der Leistungsfähigkeit des Stoßdämpfers führt.in the In general, the conventional pneumatic shock absorber is characterized by a compressible, high-pressure gas instead of conventional Spring body, being its extensible Sleeve underneath Tension the same flexibility offers. It can be however, do not achieve continuous compression when gas in compressed to a certain extent in a single enclosed space is, namely a turning point visible in the back of the compression curve becomes, from that to a strong increase the compression force for the compression movement is required. Therefore, the correspond usual pneumatic shock absorber due their very limited Area of effective movement does not meet the requirements. Furthermore is the flexible shock resistance because of the very big one Spring force of the compressed gas very low, resulting in a reduction the efficiency the shock absorber leads.
Die Erfindung hat sich daher zur Aufgabe gemacht, die obigen Probleme beim Stand der Technik zu überwinden, so daß auf diesem Gebiet der Technik durch die Schaffung eines verbesserten pneumatischen Stoßdämpfers mit gewünschter Leistungsfähigkeit ein Fortschritt erreicht wird.The Invention has therefore set itself the task of solving the above problems to overcome in the prior art, so that on this field of technology by creating an improved with pneumatic shock absorber desired capacity an advance is achieved.
Zu diesem Zweck schlägt die Erfindung eine Konstruktion vor, die langjährig entwickelt und versuchstechnisch bewertet wurde und mit deren Herstellung Erfahrungen gesammelt wurden, die zu den gewünschten Erzeugnissen geführt haben.To that purpose the invention before a design that developed many years and experimental was evaluated and experiences were gained with their production, the ones you want Products to have.
