Abstract
The articulation comprises an inner armature (4, 9) and an outer armature (5) interconnected by a mass (3,8) of elastomer, in which are formed two chambers (6, 7) filled with liquid and interconnected through a passageway (13). The articulation is formed by two elements (1, 2) each constituted by part (4, 9) of the inner armature and a part (3, 8) of the mass of elastomer defining cavities (6,7) which allow an axial removal of the mould, one (1) of the elements further comprising the outer armature (5) while the other element (2) comprises a secondary armature (10). The outer armature (5) and secondary armature (10) are interconected by a setting operation after having axially clamped together the two elements (1, 2).
