Abstract
The device is adapted to ensure the transmission of a movement of rotation between a driving shaft and a driven shaft which are adapted to be rendered respectively rigid with a first universal joint fork member (1) and a second universal joint fork member (6). The fork members each carry elements (11, 12) of the ball joint unit and are connected by spiders (14, 9) to intermediate connecting means (5). Each of the elements (11, 12) of the ball joint unit is constructed in the form of a fork member (13, 14) whose branches are engaged in the branches (3, 8) of the corresponding fork member of the articulation device and in contact with the branches (3, 8) and whose web carries a projection (22) cooperating with a complementary projection (24) provided on the other element (12). The fork members (13, 14) of each of the elements of the ball joint unit have in their branches transverse apertures (15, 16) receiving inwardly projecting portions of rolling bearings (19, 20) by means of which bearings the spiders (4, 9) are mounted in the branches (3, 8) of the fork members (1, 6) of the articulation device.
