Abstract (en)
[origin: WO9101453A1] A constant velocity universal joint for transmitting driving torque between rotative members, such universal joint including a hub fixed to one of the rotative members and an outer joint member attached to the hub, an inner joint member attached to another one of the rotative members and a ball containing cage positioned between the outer joint member and the inner joint member. The balls are engaged in ball races positioned in the outer joint member and in the inner joint member. The ball races are sloped so as to provide maximum material at the location of highest stress, the major ball races being of the undercut free design.
