Abstract:
1. A wheel bearing arrangement, comprising: at least one encoder; at least one sensor; a hub which is mounted in the wheel bearing arrangement so as to be rotationally moveable; a radial flange of the hub being aligned radially away from the rotational axis; a radial annular gap between the hub and an outer ring, the outer ring having an inner raceway for rolling bodies and the radial annular gap facing the radial flange; a seal, concentric to the rotational axis, mounted on the hub and mounted externally to the outer ring, the seal is completely external to the radial annular gap, sealing off the radial annular gap, the seal having at least one covering ring, which is made from a non-ferromagnetic material, and having at least one elastic first sealing lip, the first sealing lip being fixed to the covering ring and bearing sealingly against the encoder; at least one signal-active part of the encoder being arranged at the inside of the seal and being rotationally moveable with the hub about the rotational axis; the seal having at least one second sealing lip which bears sealingly against the radial flange; and, the sensor being arranged at the outside of the seal and opposite the encoder, and the covering ring extending at least between the encoder and the sensor.
