In order to provide solutions for soiling problems and corrosion problems in the area between a pole ring (41) and the hub interior, arranged behind it, of a wheel hub assembly having a wheel hub (1) which ends inside the vehicle in a hub section (50) whose internal circumference (15) defines an opening (55) for the central passage of the stub axle (6) and on which a fastening device (42) of a pole ring (41) of an ABS sensor is mounted, wherein a pulse generator section (43) which is embodied in one piece with the fastening section (42) is a component of the pole ring (41), which pulse generator section (43) extends from the fastening section (42) to the wheel hub axis (A) and is provided with openings (44, 44L) distributed uniformly in the circumferential direction; in a first embodiment the pole ring (41) extends with its pulse generator section (43) towards the wheel hub axis (A) to such an extent that the opening (55) between the wheel hub (1) and stub axle (6) is for the most part covered towards the interior of the hub. In a second embodiment, at least some of the openings or slots have an extent (RL) towards the outside which is greater than the extent (R) which is necessary for sensing. Furthermore, it is proposed with respect to the pole ring (41) that some of the openings (44L) or slots have an extent (RL) towards the outside which is greater than the extent (R) of other openings (44) or slots.
A wheel-hub assembly for a vehicle wheel, the wheel hub assembly comprising:
A pole ring of an ABS sensor for sensing the rotation of a vehicle wheel, the pole ring comprising an attachment portion (42) that mounts the pole ring on a radially outer periphery of a hub of a vehicle wheel, and further comprising a pulse-generator portion (43) integrally formed with the attachment portion (42), wherein the pulse-generator portion (43) extends, starting from the attachment portion (42), as a ring, closed in a circumferential direction of the pole ring (41), toward a pole-ring axis (A) in a radial direction and is provided exclusively with radial openings (44, 44L) extending in the radial direction and uniformly distributed in the circumferential direction, wherein some of the radial openings (44L) include first openings and second openings, wherein the first openings exhibit an outward radial extent (RL) in the radial direction that is larger than a radial extent (R) of the second openings (44), wherein the radial extent (R) of the second openings is required for a sensing operation of the ABS sensor, wherein the radially inner edge of the pulse-generator portion (43) is provided with a bead (48) and wherein the radial openings facilitate communication between a space defined by a first face of the pole ring and a bearing seal and a space defined in part by a second face of the pole ring which is opposite the first face.
