ABSTRACT:
A transmission joint of the sliding type has a joint body (12) and a tripode (14) having three arms (16) each of which is capable of sliding between two parallel and plane surface portions (36) by means of an articulation element (18) which is carried by the arm (16) of the tripode (14) and which comprises two parallel and opposite plane faces (20) each of which interacts with one of the plane surface portions (36) with interposition of a row of bearing needles (32), wherein the joint body (12) comprises three bearing races each comprising two tracks (38) each of which consists of a component comprising a plane surface portion (36) and a convex cylindrical surface portion (40) which interacts with a complementary concave cylindrical bearing surface (42) formed in the joint body (12) with respect to which it is capable of pivoting, and in that each arm (16) of the tripode comprises a journal on which the intermediate articulation element (18) is mounted to revolve about an axis (Y-Y) parallel to its opposite plane surfaces (20).
