DRIVE
January 2, 2013
A static sealing device (1) for a wheel hub (3), an inner ring (5) of which is associated with an outer ring (10) of a constant velocity joint (6) coupled with the wheel hub, including a first sealing assembly (14) arranged between the inner ring and an outer ring of the wheel hub to protect respective rolling bodies (9), and a second sealing assembly (15) arranged between the wheel hub and the outer ring of the joint; wherein the first sealing assembly (14) includes a shield (16) fitted to the inner ring (5) with a sleeve portion thereof and provided towards the joint with a flange portion (18) carrying, on the side opposite to the sleeve portion, an annular signal generating element (19) and a tubular support element which axially projects so as to protrude from the flange portion; the second sealing assembly (15) includes a tubular core (28), opposite ends (27, 30) of which are at least partially embedded in an elastomeric material forming at least one sealing lip (31) towards the joint (6) and an elastically deformable annular tooth (32) for coupling to the tubular support element (24), which is made with a shape complementary to the tooth (32) for snappingly receiving it and axially retaining protrudingly the second sealing assembly (15) to the first one (14).
