BEARING FOR WHEEL WITH SENSOR

摘要

A bearing for a wheel with sensors enabling the accurate detection of a load applied thereto with less number of sensors, enabling the compact installation of the load sensors on a vehicle, and enabling the stable detection of the load applied to the wheel. The bearing (18) for the wheel with the sensors comprises an outer member (1) having double rows of rolling faces (4) formed on the inner periphery thereof, an inner member (2) having rolling faces (5) facing the rolling faces (4) of the outer member (1) formed thereon, and double rows of rolling elements (3) interposed between these both rolling faces (4) and (5). Rings (9A) and (9B) having tapered outer diameter surfaces are fixed to the inner member (2). Displacement sensors (10) facing the tapered outer diameter surfaces of the rings (9A) and (9B) are integrally fitted to the outer member (1) or a member (17) fixed to the outer member (1). Distances between the rings (9A) and (9B) and the displacement sensors (10) are measured by the displacement sensors (10).
