Abstract
The invention relates to an articulation (1) for damping vibrations between an inner mechanical element and an outer mechanical element, comprising a rigid inner reinforcement (2), a rigid outer reinforcement (3), and a ring (4) made of at least one vibration damping elastomer material, which ring radially extends around the axial direction (X) between the inner reinforcement (2) and the outer reinforcement (3). The invention is characterized in that the first side flank (41) of the ring (4) comprises a first ring portion (51, 52) defined by a first surface (411, 412) and a second ring portion (53, 54) defined by a second surface (413, 414), which are diametrically opposed in relation to the axial direction (X) and which have, in the axial direction (X), respectively a first axial elevation (X1, X2) and a second axial elevation (X3, X4), which is higher than the first axial elevation (X1, X2).
