Abstract
The anti-vibration suspension device comprises at least three oblique bars pivotably mounted each on the gearbox and on the structure, by means of a rigid lever supporting a vibrating weight and in turn pivotably mounted on this structure, and each lever is also linked to the structure by at least one torsion spring biased about a torsion axis substantially perpendicular to the radial plane defined by the axes of the rotor and the corresponding oblique bar.
