ABSTRACT:
A joint comprises a tripod equipped with three spherical pivots, and a barrel with six cylindrical inner tracks. Intermediate elements comprise a cylindrical surface complementary with the spherical pivot and a surface of circular profile complementary with the circular profile of the tracks. The intermediate elements are blocks, the surface of circular profile of which is a cylindrical surface permanently bearing slidably in the tracks. The joint enables reducing the contact pressures, increasing the telescopic stroke, simplifying the form of the intermediate elements and making it possible to produce them from a material of moderate hardness.
