HUB BEARING CONSTANT VELOCITY JOINT

Hub bearing constant velocity joint in which a radially outer, annular, element of the joint is engaged with an annular hub of a hub bearing unit with a flange at a first end thereof by means of a clamping system including a screw element assembled inside the annular joint element and able to be operated on the outer side through the annular hub so as to screw it inside a second end of the hub until it prestresses the rolling bodies of the hub bearing unit, while the transmission of torque is ensured by a splined coupling between the joint element and the second end of the hub; the screw element is axially locked against an annular shoulder formed on the inside of the joint element, on the opposite side to the annular hub, by means of an elastic ring engaged with at least one annular seat formed on the inside of the joint element.
