||PCT/DE2014/000064||BALLUFF GMBH||KÁNTOR, Zoltán|
The invention proposes a position measuring apparatus (12, 13) for measuring the position (s) of an electrically conductive measurement object (28) which can be moved over a measurement section (18), along which coils (14; 14a, 14b; 16) are positioned. The position measuring apparatus (12, 13) is distinguished by the fact that a measuring coil (16) is provided between every two excitation coils (14; 14a, 14b), through each of which excitation coils an alternating excitation current (20) flows, which current is predefined to be in phase opposition from excitation coil (14; 14a, 14b) to excitation coil (14; 14a, 14b). The alternating magnetic fields (22) produced by the alternating excitation currents (20) induce eddy currents in the electrically conductive measurement object (28) when the measurement object (28) moves past the excitation coils (14; 14a, 14b). The measuring coils (16) provide an AC measurement voltage (30, 30', 30'',...)which is induced by the eddy currents flowing in the measurement object (28) when the measurement object (28) moves past the at least one measuring coil (16). The position (s_Mess) of the measurement object (28) is determined on the basis of the at least one AC measurement voltage (30, 30', 30'',...).

The invention relates to a wheel bearing arrangement (21a) of a vehicle axle, comprising a wheel bearing (22), which contains at least two rolling element rows, for bearing a wheel hub (30) which can be driven by a drive element. The rolling elements (23) of the wheel bearing (22) are guided in tracks (24, 26) of a stationary outer ring (25), the rotating wheel hub (30), and a separate inner ring (27a) which is paired with the wheel hub (30). In the assembled state, the wheel hub (30) of the wheel bearing arrangement (21a) and the drive element are operatively connected via a toothing. A radially stepped inner contour (28) of the inner ring (27a), said inner contour having two diameters (D1, D2) which differ from one another, is adapted to a complementarily designed receiving area (29) of the wheel hub (30). The position of the inner ring (27a) is fixed on the end face by means of a rolling rivet connection (31) of the wheel hub (30).
