摘要

The invention proposes a sliding type universal joint comprising a joint body (12) and tripot (14) including three arms (16) each one (16) of which is capable of sliding between two plane and parallel surface portions (36) through the use of an articulation element (18) which is carried by the arm (16) of the tripot (14) and which includes two opposite and parallel plane faces (20) each of which interacts with one of the plane surface portions (36) with interposition of a row of roller bearing needles (32), characterised in that the joint body (12) includes three bearing paths each one including two tracks (38) each of which consists of a component including 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 tripot includes a journal on which the intermediate articulation element (18) is mounted so as to rotate about an axis (Y-Y) parallel to its opposite plane surfaces (20).
