    摘要： An anti-friction bearing (2) consisting of an outer ring (8) mounted around an inner ring (10) is disclosed. One of the seals (14) that seal the bearing (2) incorporates an encoding element rotationally secured to the rotating ring (8), and comprises a core element with a radial extension extending along the side surface of the rotating ring (8) of the bearing (2). A hub (1) comprising such a bearing (2) is also disclosed. The thickness, in the axial direction of the bearing (2), of the radial extension of the core element of the seal (14) that includes the encoding element is the same as the axial offset caused between the stub-axle carrier (4) of the hub (1) and the inner ring (10) of the bearing (2) by the means for attaching the sensor element to the stub-axle carrier (4).

    摘要： The invention concerns a method for electric diagnosis of an oxygen sensor of an internal combustion engine functioning on several richness values and in particular on a lean burn, characterised in that it consists in the following steps: monitoring the functioning of the engine and when predetermined functioning conditions are observed in which the richness of the carburetted mixture remains different from the stoichiometry for a sufficient time interval, measuring the voltage level of the signal emitted by said oxygen sensor; comparing this voltage value to a polarisation value and deducing therefrom if said voltage value is substantially equal to the polarisation voltage the existence of a fault in the electric connection of the sensor, or otherwise the absence of fault in the sensor electric connection.

    摘要： The invention discloses a rotating shaft (1), equipped with a device for measuring the torsional moment comprising two units (11) for detecting the magnetic field symmetrically arranged with respect to the shaft (1), mounted on a first support (9, 10) attached at right-angles relative to a first point (A) on the axis of the said shaft (1), and two magnetic field generators (13) arranged symmetrically with respect to the shaft (1), mounted on a second support (12) attached at right-angles relative to a second point (B) of the axis the said shaft, the first (A) and the second (B) points being axially offset with respect to each other. The invention is characterised in that the internal ring (4) of a first rolling bearing (7) is machined at the periphery of the shaft (1), at right-angles to the attachment point (B) of one of the supports (9, 10; 12), the so-called main support (12).
