Slidable homokinetic joint, in particular for a lateral vehicle transmission

A homokinetic joint comprising a first element extending along a first axis and carrying three radial arms evenly angularly spaced apart and defining spherical bearing surfaces, a second element having a second axis intersecting the first axis and capable of making an angle therewith, said second element defining three pairs of raceways, six intermediate elements, each of which is disposed between a respective one of said spherical bearing surfaces and a respective one of said raceways, rolling members being interposed between the intermediate elements and the adjacent raceways, wherein the raceways provided on the second element are cylindrical surfaces having a substantially circular cross-section and generatrices parallel to the axis of the second element and each intermediate element comprises on the side thereof facing the adjacent raceway, a raceway having a substantially cylindrical shape and a circular cross-section similar to that of the adjacent raceway on the second element and generatrices parallel to the axis of the second element, wherein each intermediate element undergoes an oscillating movement about the axis of the associated raceways when the joint operates at an angle, and the rolling members interposed between the intermediate elements and the raceways on the second element are balls.
