ABSTRACT:
A telescopic homokinetic joint which is capable of filtering vibrations coming from the driving means and is also devoid, or substantially devoid, of periodical internal friction. This result is obtained in a homokinetic joint comprising a first element including three pairs of planes which are evenly angularly spaced apart about a first axis, the planes of each pair being parallel to each other and to said axis, a second element defining three spherical bearing surfaces which are evenly angularly spaced apart about a second axis, and intermediate elements. The intermediate elements comprise planar surfaces which are respectively parallel to the planes and spherical surfaces which cooperate with the spherical bearing surfaces. According to the invention, rolling elements are interposed between the planar surfaces of the intermediate elements and the planes of the first element.
