  • Patent number: 7628540
    Abstract: A bearing device for a wheel, where preload control is easy and a uniform amount of preload can be applied even if a bearing seal is installed in the bearing device. The bearing device rotatably supports a wheel and has an outer member 1, an inner member 2, and rolling elements 3 interposed between both members. The outer member 1 has on its outer periphery a vehicle body installation flange 1a, and double row rolling surfaces 6, 7 are formed on the inner peripheries of the outer member. Rolling surfaces 8, 9 facing the rolling surfaces 6, 7 of the outer member 1 are formed in the inner member 2. Between the rolling surfaces of both members 1, 2 are interposed the rolling elements 3. A sensor 4 for detecting the amount of preload of the bearing is provided on either the outer member 1 or the inner member 2.

  • Patent number: 7604413
    Abstract: A wheel support bearing assembly comprises a stationary outer member and a rotatable inner member. The to-be-detected parts of angle detection sensors are fixed to the inner member and an outer race of a constant velocity joint connected to the inner member, respectively. Detecting parts of the angle detection sensors are fixed to the outer member in face-to-face relation with the to-be-detected parts. The bearing assembly also includes a load conversion unit detecting a relative angular difference between the inner member and the constant velocity universal joint by comparing the detection signals from the detecting parts to detect the load acting on the bearing assembly.

    Abstract: The bearing assembly includes a rolling bearing including a rotatable raceway member and a stationary raceway member. This bearing assembly also includes a to-be-detected member carried by the raceway member and having a magnetic characteristic which cyclically varies in a direction circumferentially of the to-be-detected element and has a cycle matching with one complete rotation of the raceway member, a magnetic sensor unit carried by the raceway member in face-to-face relation with the to-be-detected member, and a magnetic detecting circuit to supply an electric power to the unit and to process an output signal from the unit to provide an output to an external circuit. The magnetic characteristic of the to-be-detected member represents a substantially sinusoidal waveform rising and falling more steeply than a sinusoidal waveform at a zero-crossing point.
