Abstract
a sliding universal joint has a male element (1), especially a tripod, intended to be fixed to a first shaft and including arms (6) on each of which a roller (3) with a spherical external surface is mounted so that it can rotate and slide. A female element (2) intended to be fixed to a second shaft and defines on each side of each spherical roller two runway paths (7,8). A first of these runway paths (7) interacts directly with the spherical roller and axially positionins it. Between each spherical roller (3) and the associated second runway path (8) there is interposed an anti-vibration assembly (4) which, on the inside, includes a spherical surface which substantially matches the external surface of the spherical roller and interacts with this surface. This assembly (4) moves along the second runway path (8).
