Arrangement of a wheel hub connected to a constant velocity joint provided with a low friction seal device

摘要

An arrangement (1) including a first and second sealing assembly (14, 15) interposed between an inner ring (5) and an outer ring (8) of the wheel hub (3) and straddling the wheel hub (3) and an outer ring (10) of a constant velocity joint, and an annular step (25) obtained on the side of the constant velocity joint on a radially outer lateral surface (26) of the inner ring, in a position adjacent to a sleeve portion (17) of a first shield (16) of the first sealing assembly from which a flange portion (18) radially extends so as to protrude towards the outer ring, the flange portion being provided towards the constant velocity joint (6) with a signal generating element (19) consisting of an annular insert (19b); an end (27) of a tubular core (28) of the second sealing assembly is fitted angularly onto the step (25) and is radially externally provided with an L-shaped edge (31) arranged within the step (25) and radially under the annular insert.
