Provided is an integrated wheel speed measuring device. The integrated wheel speed measuring device includes: a hub installed in a wheel bearing; a magnetic encoder which is inserted into a recess part prepared on a side of the hub; and a wheel cap which surrounds the side of the hub and the recess part. The encoder is cylindrical and is installed to the recess part in the length direction of the recess part. The magnetic encoder is formed at the inside of the hub. The area of the encoder is increased by controlling the inside depth of the hub. Thus, a target sensing value can be satisfied. At this time, a sensor is assembled with the wheel cap by an O-ring, so that the sealing structure of a bearing can be maintained. Also, the encoder is integrated with the hub so that a separate encoder ring is not required. Also, an inside seal is not required by applying a wheel bearing cap so that costs can be reduced. |
