20110214513 | Sensor-equipped bearing for wheel - A sensor equipped wheel support bearing assembly, in which the load imposed on the wheel support bearing assembly or a tire tread of a wheel tire can be accurately detected without being affected by the rolling elements, includes rolling elements interposed between plural opposed rolling surfaces defined in outer and inner members. One of the outer and inner members that serves as a stationary member is provided with one or more sensor unit. The sensor unit includes a strain generating member, having two or more contact fixing segments fixed to the stationary member, and a sensor for detecting such strain. The strain generating member in the sensor unit is arranged at a position departing from a line passing through a center of the rolling elements and extending in a direction defined by the rolling element contact angle. | 09-08-2011 |

20120014632 | SENSOR-EQUIPPED BEARING FOR WHEEL - A sensor-equipped wheel support bearing assembly capable of accurately estimating a load acting on a wheel, without the detecting accuracy deteriorated as a result of a long term use and/or a change in environment, is provided. The assembly includes a sensor unit provided in an outer member, which serves as a stationary member. The sensor unit has a strain generator and a sensor for detecting a strain occurring in the generator. A principal load estimator estimates the load acting on the wheel, with the use of an average value of a signal from the sensor, and an amplitude processed load estimator estimates the load, using amplitude of a signal wave outputted from the sensor, resulting from passage of rolling elements. A drift amount estimator estimates a drift amount of an estimated load output utilizing the average value and the amplitude, which is used to correct the estimated load. | 01-19-2012 |

20140287841 | TRIPOD TYPE CONSTANT VELOCITY UNIVERSAL JOINT AND METHOD FOR PRODUCING SAME - A tripod type constant velocity universal joint includes an outer joint member including three track grooves having roller-guide surfaces arranged to face each other in a circumferential direction, a tripod member including three leg shafts projecting in a radial direction, and roller units each including a roller and an inner ring for supporting the roller in a freely rotatable manner. The inner ring is externally fitted to corresponding one of the three leg shafts. The roller is movable along the roller-guide surfaces of corresponding one of the three track grooves. Each of the three leg shafts includes a region formed into a substantially circular-arc shape in horizontal cross-section that is orthogonal to an axial line of the each of the three leg shafts. | 09-25-2014 |
