A wheel hub bearing for motor vehicles including a rotatable hub provided with a flange for the engagement of the hub to a wheel of a vehicle and provided with a radially outer free portion and a bearing unit provided with a radially outer ring for the engagement of the wheel hub bearing to a knuckle of the vehicle and a radially inner rotatable ring angularly connected to the hub. Furthermore, the wheel hub bearing has a device for detecting a vehicle parameter and provided with an encoder and a sensor in communication with the encoder. The encoder is ridgidly coupled to the radially outer free portion of the flange to jointly rotate with the hub.

A wheel hub assembly includes inner and outer hubs rotatably coupled by first and second ballsets of rollers. A plurality of sensors for sensing strain within the outer hub generated by the ballsets are disposed on exterior mounting surface sections. These surface sections are located at radial spacing distances within empirically derived radial boundaries to prevent interference from one ballset affecting the measurements taken by sensors monitoring the other ballset. To prevent excessive distortion of strain measurements taken through the outer hub, a certain amount of hub material is required to smooth signals generated by the first and second rollers passing proximal to each sensor, thus affecting the radial location of the mounting surfaces. Further, the sensor mounting surface sections are also located within empirically derived axial boundaries determined to enable each sensor to sense strain from one ballset while avoiding the detection of strain generated by the other ballset.

There is provided a wheel bearing for rotatably mounting and supporting a wheel of a vehicle to a vehicle body. The wheel bearing includes a rotary element on which the wheel of the vehicle is mounted and which rotates together with the wheel; a non-rotary element mounted on a chassis component of the vehicle and fixed to the vehicle body; and one or more rolling elements provided between the rotary element and the non-rotary element and configured to rotatably support the rotary element relative to the non-rotary element. The rotary element includes a wheel mounting flange used for mounting the wheel, and a tone wheel or an encoder configured to measure a rotational speed of the wheel may be mounted on a vehicle-body-side end surface of the wheel mounting flange.
