1. A fixed constant-velocity ball joint comprising:a bell adapted to be made integral with a first shaft, a cavity of said bell being at least partly spherical and incorporating six first grooves, a director line of each first groove being contained within an axial half-plane of the bell; a hub adapted to be made integral with a second shaft, an exterior surface of said hub being at least partly spherical and incorporating six second grooves, a director line of each second groove being contained in an axial half-plane of the hub; six balls partly received in respective pairs of said first and second grooves; and a cage for maintaining said balls in a bisector plane of said joint when said joint is broken, said cage having spherical exterior and interior surfaces substantially conjugate with spherical surfaces of said bell and of said hub, respectively, the enters of said director lines of said two grooves in each of said axial half-planes, in the aligned position of said joint, being offset axially and symmetrically relative to the transverse diametral plane of said joint and offset radially by the same distance relative to the central axis of said joint on the side opposite said grooves, wherein said radial offset is from approximately 15% to approximately 25% of a pitch circle diameter of said joint.
