Abstract

L'invention porte sur un mécanisme à rigidité variable (102) qui comprend un ensemble de deux ressorts (121 et 122), un levier (130) ayant un emplacement de réception (134) destiné à recevoir une force extérieure et un élément pivot (140) accouplé au levier de façon coulissante. Le mécanisme de suspension variable comprend un actionneur (150) destiné à déplacer l'élément pivot qui amène un pivot (136) du levier à se replacer. Une rigidité efficace du mécanisme de suspension variable par rapport à une force extérieure appliquée à l'emplacement de réception est une fonction rationnelle qui dépend au moins des constantes élastiques des deux ressorts et d'une position de l'élément à pivot par rapport aux deux ressorts. Un système de suspension (100) comprend le mécanisme à suspension variable accouplé à un ressort classique (106) dans un arrangement en série.
