Patent ID: 8720904

Claim:
A static seal device for wheel hubs connected to constant velocity joints comprising: a first sealing assembly interposed between an inner ring and an outer ring of the wheel hub, and a second sealing assembly integrally supported by the inner ring and arranged straddling the wheel hub and an outer ring of the constant velocity joint, and wherein the first sealing assembly has a first shield anchored to the inner ring by means of a sleeve portion and provided with a flange portion on a first side of the joint, which radially extends so as to protrude from the sleeve portion and towards the outer ring of the wheel hub, externally carrying a signal generating element towards the joint, the signal generating element consisting of an annular insert, and wherein the annular insert is shaped so as to leave uncovered an annular radially inner area of the flange portion, the annular radially inner area being immediately adjacent to a radially outer lateral surface of the inner ring on which the sleeve portion of the first shield and a second end of a tubular core of the second sealing assembly are fitted immediately adjacent to each other, and wherein the inner ring defines an annular seat frontally open towards the joint between itself, the uncovered annular area of the flange portion of the first shield, and the radially outer lateral surface of the inner ring, and wherein the first end of the tubular core of the second sealing assembly faces the opposite side of the joint and is provided radially on the outside with an L-shaped edge, shaped so as to be coupled within the annular seat substantially flushed with a face of the annular insert facing towards the joint.
