The H2 is a passive system which replaces existing dampers with simple double acting cylinders. Each cylinder performs the normal wheel/body damping functions using conventional or advanced damping technology incorporated within the cylinders. All cylinder chambers (8 chambers in total – 2 per wheel) are interconnected using relatively small hydraulic lines. The interconnection provides extremely high levels of roll stiffness while passively maintaining low levels of single wheel and articulation stiffness. The interconnection also provides the opportunity to incorporate roll damping independently of wheel/body damping. The system also incorporates small accumulators at various positions depending on the design specification and vehicle parameters.
