Abstract

L'élément essentiel de cette suspension de siège est un organe hydraulique 9 comprenant un cylindre 10 et un piston 11 et constituant à la fois un support élastique et un amortisseur. Son cylindre est relié par un raccord 126 à une pompe 31 qui peut alimenter d'autres équipements du véhicule et par un raccord 128 à un accumulateur hydropneumatique 30, à travers une vanne d'étranglement 29 à commande manuelle qui permet de régler la dureté de la suspension. Deux parallélogrammes articulés 14, 15, 17, 18 de part et d'autre de l'assise 6 du siège et d'une embase 8 guident le mouvement de suspension vertical du siège. L'embase 8 est montée sur le châssis du véhicule par l'intermédiaire d'un mécanisme de réglage en hauteur qui permet de régler la hauteur d'une position normale du siège indépendamment du poids de l'utilisateur.
