(FR) JAMBE DE SUSPENSION HYDROPNEUMATIQUE
(DE) HYDROPNEUMATISCHES FEDERBEIN
Abstract: front page image
(EN) Hydropneumatic suspension strut (1) comprising a piston-cylinder unit that includes a first gas spring (5) and a second support spring, the gas spring (5) and the support spring (45) being mounted in parallel and acting in the same direction, the suspension strut (1) being adjustable to at least two vertical levels, and the second support spring (45) having a spring rate that increases as the effective length of the suspension strut (1) decreases.
(FR) L'invention concerne une jambe de suspension (1) hydropneumatique comprenant un ensemble piston-cylindre pourvu d'un premier ressort (5) pneumatique et d'un second ressort de suspension, le ressort (5) pneumatique et le ressort (45) de suspension étant reliés en parallèle et présentant une même direction d'action, la jambe de suspension (1) pouvant être réglée sur au moins deux niveaux de caisse, le second ressort (45) de suspension présentant une constante de rappel qui augmente lors d'une réduction de la longueur d'action de la jambe de suspension.
(DE) Hydropneumatisches Federbein (1), umfassend ein Kolben- Zylinderaggregat mit einer ersten Gasfeder (5) und einer zweiten Tragfeder, wobei die Gasfeder (5) und die Tragfeder (45) parallel geschaltet sind und eine gleiche Wirkrichtung aufweisen, wobei das Federbein (1) auf mindestens zwei Niveaulagen einstellbar ist, wobei die zweite Tragfeder (45) eine mit einer Reduzierung der Wirklänge des Federbeins (1) ansteigende Federrate aufweist.
