Abstract
The elastically yieldable articulation is of the type comprising a cylindrical outer armature and a coaxial inner armature interconnected by a block of elastomer material and movable with respect to each other. According to the invention, the articulation comprises at least one deformable sealed chamber filled with a liquid and arranged between two portions of each of the two armatures so as to increase the elastic stiffness of the articulation in a direction (T) of relative displacement of the armatures substantially perpendicular to an axial plane (P) of the articulation and at least in a direction corresponding to an approach between these portions. Application in particular in the mounting of a set of wheels of a vehicle.
