摘要： A combined sensor and bearing assembly (1) is of a type having a capability of detecting a point of origin and includes a rolling bearing unit (6) and a rotation sensor unit (31). The rolling bearing unit (6) is made up of a rotatable raceway member (4), a stationary raceway member (5) and at least one row of rolling elements (3). The rotation sensor unit (31) includes a to-be-detected member (8) having a magnet and fitted to one of the raceway members (4, 5), and a magnetic detecting member (9) fitted to the other raceway member (4, 5) at a location confronting the to-be-detected member (8). This combined sensor and bearing assembly (1) is used at a location close to an electromagnetic coil (17) emanating a leakage magnetic field, in a condition in which a direction of flow of an electric current through the electromagnetic coil (17) is fixed in one direction so that a direction of a magnetic flux, with which the magnetic detecting member (9) is switched off, may coincide with a direction of the leakage magnetic flux.

The inner member has a corresponding number of raceway grooves defined in the hub axle and the inner race segment, respectively. Rows of rolling elements are interposed between the outer member 1 and the inner member. A to-be-detected member in the form of a magnetostrictive element is formed in a portion of the outer periphery of the hub axle adjacent an inboard side and remote from the raceway groove. At least one force detecting unit for detecting a change in magnetic strain induced in the to-be-detected member is provided in an outer race, which is a non-rotatable member, for detecting a force acting on a shaft coupled with the inner member.

摘要： 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.
