Abstract: A vehicle hub bearing unit including an outer ring; a wheel hub rotating about a common axis of symmetry of the outer ring and of the wheel hub; a wheel flange that extends radially from the wheel hub on the outside of the outer ring; a plurality of rolling bodies interposed between the outer ring and the wheel hub; at least one sealing assembly arranged on the side of the wheel flange, which is delimited towards the outer ring by a radially extending first face; and a protective ring that surrounds the outer ring and which radially extends in a position facing the first face of the wheel flange and beyond a first annular step of the first face that protrudes axially; a radially outer section of the protective ring overhangingly axially extending from the outer ring towards the wheel flange and axially beyond the first annular step.

Abstract: A hub-bearing assembly serves to rotatably mount a soil-working disc (D) on a supporting axle (A) of an agricultural machine. The assembly comprises a hub-bearing unit (10) and a sealing device (20). The a hub-bearing unit has a radially outer, rotatable outer race (11) from one side of which a flange (12) radially extends for mounting a disc (D). The sealing device (20) is mounted on a side of the hub-bearing unit opposite to the side of the flange (12). The radially outer surface of the assembly has a portion (38) intermediate the flange (12) and the side of the sealing device (20), which is radially recessed so as to serve as a preferential seat for winding wires picked up from the fields during use of the agricultural machine.

Abstract: Sealing device (1) for a wheel hub group (2) which is connected to a differential device, and which is provided with a rolling contact bearing (3), the sealing device being provided with a first shield (6) which is shrink-fit onto an inner race (4) of the rolling contact bearing (3), and an encoder (7) which is integral with the first shield (6) in order to generate a signal for reading the functioning kinematic parameters of the wheel hub group (2), and is also provided with a second shield (8) which is shrink-fit onto an outer race (5) of the rolling contact bearing (3) in a position which is opposite to and which is also external to the inner shield; a static sealing element (12) is integral with the second shield (8), and is also arranged in contact with a containing box of the differential in order to define a watertight chamber (14) in order to provide a reading surface of a reading sensor (11) which can read the signal which is generated by the encoder itself.

Abstract: Sealing device (1) with an encoder (7) which is suitable for reading the kinematic parameters of the functioning of a rolling contact bearing (3), the device (1) presenting a first shield (6) which is shrink-fit onto an external surface (42) of an inner race (4) of the contact rolling bearing (3) in order to support the said encoder (7), and a deformable blocking device (11), which is obtained on the first shield (6) and which is engaged in a circular groove (44) which is obtained on the external surface (42) in order to axially block the first shield (6) itself onto the inner race (4) while leaving free a contact portion (45) of the external surface (42) itself.
