Abstract

L'invention concerne un ensemble d'essieux (10) pour un véhicule, en particulier un véhicule de loisir à trois ou à quatre roues, comportant un support d'essieu central (11) et des supports de roue (13, 14) raccordés individuellement de manière articulée audit support pour une roue de véhicule côté gauche et côté droit. Les deux supports de roue s'appuient sur le support d'essieu en insérant des amortisseurs hydrauliques (30), dont les espaces annulaires (34) et les chambres de piston (35) sont reliés ensemble en croix par des conduites de débordement (36). Selon l'invention, chacune des conduites de débordement reliant ensemble en croix les espaces annulaires et les chambres de piston des amortisseurs est reliée à un réservoir de compensation (38), et la liaison de respectivement au moins une des conduites de débordement et du réservoir de compensation peut être séparée au moyen d'une soupape pouvant être commutée et soumise à l'effet d'un capteur de courbe. Un virage pris par le véhicule est constaté à l'aide du capteur et, en conséquence, la soupape disposée entre la conduite de débordement allant de la chambre de piston de l'amortisseur côté extérieur du virage à l'espace annulaire de l'amortisseur côté intérieur du virage et le réservoir de compensation associé est commutée, ce qui permet de verrouiller les supports de roue ensemble sur le côté gauche et le côté droit du véhicule et d'empêcher le véhicule de subir un roulis.
