  • Patent number: 11673423
    Abstract: 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.
