ABSTRACT:
The joint comprises a male element drive in rotation by a driving shaft (AM) and provided with radial arms (340) on each of which are mounted two rolling segments (310) trapped in rolling tracks (R) of a female element (312), expansible elastically yieldable bearing bushings (600) interposed between the arms (340) and the rolling segments (310), each bushing being formed by two semi-cylindrical semi-bushings (600) which are prevented from moving axially and in rotation relative to the arm (340) and are radially expansible. Each semi-bushing (600) is provided with a stud (410) for locating it on the associated arm (340), this stud being placed inside the semi-bushing on the axis of symmetry (Y--Y') of the latter. This arrangement avoids any risk of breakage of the bushings when the joint is operating at maximum angularity by avoiding any sudden increase in the retaining force of the locating studs in this extreme position of the joint.
