PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor capable of preventing a sensor from failing due to the influence of the external environment, accurately detecting the load acting on a bearing for a wheel or a tire surface in contact with ground for a long term, and facilitating cable wiring, and sensor installation. SOLUTION: In the wheel bearing with the sensor, a rolling element 5 is interposed between double-row rolling surfaces 3, 4 of an outer member 1 and an internal member 2 so as face each other. An electronic part including a plurality of sensor units 20, a signal processing IC 25 for processing the sensor output signal, and a signal cable 26 for taking out the processed output signal out of the bearing is arranged inside of an annular protective cover 27 to make an annular sensor assembly 28. The sensor assembly 28 is concentrically fixed with a fixed-side member on the peripheral surface of the fixed-side member. COPYRIGHT: (C)2010,JPO&INPIT |
