ABSTRACT:
Resilient joint with differentiated radial rigidity, of the type comprising a resilient material block (3) bonded between two tubular frames (1, 2) which are coaxial at rest, and which may be caused to pivot with respect to each other about their axis, said resilient material block (3) being then subjected to a shearing action under twisting, this block further including, along its periphery, variations of section so as to have unequal rigidity under compression in at least two different radial directions, characterized in that said variations of section are progressive, thus resulting in a thickness of resilient material (3)--measured in directions parallel to said axis--which is progressively variable between ridges (12) and hollows (13), without interruption of continuity.
