| 摘要 |
The invention concerns an elastic articulation designed to operate in torsion and comprising an elastomeric sleeve (7) whereof the inner and outer peripheral surfaces are linked without any possibility of sliding respectively to inner (8) and outer (9) reinforcements, and which is configured such that the articulation should have a minimal radial rigidity along a first reference axis (Z') of a system with three reference axes (X', Y, Z') whereof the second reference axis (Y) merges with the axis of the elastic articulation (5), at least one of the two end surfaces (7a and 7b) of the sleeve (7) has a profile which continuously moves in the circumferential direction of the sleeve between at least a minimum and at least a maximum, the minimum or minima and the maximum or maximums of the profile in the inner peripheral zone of the end surface being offset by a predefined angle respectively relative to the minimum or minima or to the maximum or maximums of the profile in the outer peripheral zone of the end surface.
