Abstract
A sensor-incorporated wheel support bearing assembly including double rows of rolling elements interposed between respective raceways of outer and inner members opposed to each other, a to-be-detected ring having an eccentric or multangular outer diametric shape provided in the inner member and displacement sensors provided on the outer member confronting the to-be-detected ring. In the bearing assembly, the displacement sensors have facing portion areas, variable and invariable, respectively, arranged with rotation of the to-be-detected ring.
Claims10
A sensor-incorporated wheel support bearing assembly for rotatably supporting a wheel relative to a vehicle body structure, the assembly comprising:
- an outer member having an inner peripheral surface formed with a plurality of raceways defined therein;
- an inner member formed with raceways defined therein that are respectively opposed to the raceways in the outer member and coupled with the wheel;
- a plurality of rows of rolling elements interposed between the raceways that are opposed to each other;
- a to-be-detected ring provided on the inner member and having an eccentric or multangular outer diametric shape;
- and
- first and second displacement sensors provided on the outer member,
- wherein the first displacement sensor is arranged to have a facing portion area thereon, which faces the to-be-detected ring, variable with rotation of the to-be-detected ring, and the second displacement sensor is arranged to have a facing potion area thereon, which faces to the to-be-detected ring, invariable with rotation of the to-be-detected ring.

- and
- displacement sensors provided on the outer member,
- wherein each of the displacement sensors is arranged to have a facing portion area thereon, which faces the to-be-detected ring, variable with rotation of the to-be-detected ring, and the displacement sensors are arranged symmetrically on each side of the to-be-detected ring to form a sensor unit, and
- wherein the one or a plurality of the sensor units are arranged in a circumferential direction of the to-be-detected ring.
