Abstract
A constant velocity transmission joint having a male element ( ) having a plurality of arms ( ); a female element ( ) defining a pair of facing tracks ( ) for each arm ( ), which tracks are situated on opposite sides of the arm; and, mounted on each arm, a mechanical transmission member ( ) that is movable in the longitudinal direction of the pair of tracks ( ), being held axially by the tracks, and establishing a connection with the arm that is swiveling and axially movable along the axis (Y—Y) of the arm. The transmission member includes a circularly symmetrical outer roller placed between the corresponding tracks to roll on one or other of them. For each arm, the outside profile in meridian half-section of the outer roller ( ) comprises two arcs ( A, B) having curvature of the same sign and cooperating with two arcs ( A, B) of the substantially complementary profile of the associated tracks ( ) so as to form two spaced-apart contact zones ( A, TB). The invention is applicable to constant velocity joints for motor vehicle transmissions.
