    A constant speed joint differs from the prior art in particular by the fact that it does not include rolling members. The joint includes a bell element, a spider element and three yokes which are mounted, on one hand, at the ends thereof on the bell element to pivot about first axes and, on the other hand, in the central part thereof, on the spider element by means of double pivotal mountings allowing pivotal motion about second and third axes, the pivotal mounting having the third axis also allowing a sliding motion.

    The hinges (Figs. 2 and 8) transmit the torques between the shafts, the angle between which can reach 50. B.pagodar described arrangement of links and their mates hinges can transmit axial forces in opposite directions, since the intersection point
    the rays of the star remain stationary relative to the bowl at any arrangement of links. When replacing cylindrical surfaces with the axis V-V (V, -V,) of the conjugate links to spherical in the hinges (Fig. 2 and 8), some axial sliding of the bowl relative to the star can be achieved ..
