Abstract
L’invention concerne un dispositif de suspension inertielle hydraulique pour véhicule, comprenant - un vérin délimitant une chambre de détente (C1) et une chambre de compression (C2) ; - des chambres de compensation (S1, S2) correspondantes, - un circuit de fluide (Ci) correspondant incluant des augmentateurs inertiels correspondant (IS1, IS2), et un augmentateur inertiel principal (IP) dans une branche parallèle (Bip), caractérisé en ce que le circuit de fluide (Ci) comprend en outre au moins une deuxième branche parallèle (Bs1, Bs2) connectée à une troisième chambre de compensation (S3) associée à au moins un moyen de réduction de débit (R1, R2) et/ou au moins un moyen d’orientation de flux (Cl2, Cl3) dans un sens de vidage de troisième chambre de compensation (S3). L’invention concerne également une méthode de mise en œuvre de suspension inertielle hydraulique correspondante, ainsi qu’un amortisseur et un véhicule comprenant un tel dispositif de suspension inertielle hydraulique.
