Sensor-Equipped Bearing for Wheel
First Claim
1. A sensor equipped wheel support bearing assembly for rotatably supporting a vehicle wheel relative to a vehicle body structure, which assembly comprises:
- an outer member having an inner periphery thereof formed with a plurality of raceways;
an inner member formed with raceways in face-to-face relation with the respective raceways in the outer member;
a plurality of rows of rolling elements interposed between the respective raceways in the outer and inner members; and
a sensor unit including a sensor mounting member having bolt insertion holes defined therein in a relation alignable with respective vehicle body fitting holes defined in one of the outer member and the inner member that serves as a stationary member and at least one strain sensor mounted on the sensor mounting member, and fixedly sandwiched between the stationary member and a knuckle by means of bolts inserted through the vehicle body fitting holes and the bolt insertion holes,wherein the sensor unit has a portion that has a radial dimension greater than that of a flange provided in the stationary member in contact with the knuckle.

Abstract
To provide a sensor equipped wheel support bearing assembly, in which a load sensor can be snugly and neatly installed in automotive vehicle and which detects the load or the like acting on a vehicle wheel and requires an inexpensive cost in mass production. A sensor unit is fitted to an outer member as a stationary member of the bearing assembly. The sensor unit includes a sensor mounting member having bolt insertion holes alignable with vehicle body fitting holes of the outer member, and a strain sensor fitted to the sensor mounting member. This sensor unit is sandwiched between the outer member and a knuckle and is fitted by means of bolts inserted through the vehicle body fitting holes and the bolt insertion holes. The sensor unit has a portion that is greater in a radial direction than a flange of the outer member.
