Abstract:
A rotational coupling of the flange (14) of a driving wheel to an output member (12) of a transmission joint, in which the wheel flange (14) is mounted to rotate freely through a wheel support (16) by means of a rolling-contact bearing (18), an inner race assembly (60, 62; 158) of which is made integral with the wheel flange (14) by a driving connection (68, 70; 74), the wheel flange (14) and the output member (12) of the Joint including complementary coupling means (19), which complementary coupling means (19) include a ring (40, 46; 90; 110; 122; 162) attached to the end of the flange facing the output member (12) and integral with said inner race assembly (60, 62; 158), said ring (40, 46; 90; 110; 122; 162) including driving profiles (44, 48; 114; 130; 164) designed to interact with complementary profiles (54; 115; 134, 136; 166) integral with said output member, the force-transmission interface of said driving profiles (44, 48; 114; 130; 164) being distributed essentially outwardly of the extension of the end of the wheel flange (14) bearing said ring (40, 46; 90; 110; 122; 162), wherein said driving connection (68, 70; 74) between the inner race assembly (60, 62; 158) of the bearing and the wheel flange (14) extends at least partially into the region delimited axially between the outer ends of the rolling bodies (28) of the bearing (18).
