Abstract: Device 1 for detecting the angular position of a shaft of an electric motor relative to a nonrotating element, comprising a reduction gear 5 comprising an input connected in rotation to the shaft 2, and an output such that the output of the reduction gear 5 moves over an angle of less than 2?, a single-revolution angular position sensor 26 being placed to measure the angle of the output of the reduction gear 5 and an angular position sensor 27 being placed on the input of the reduction gear 5.

Abstract: A device 10 for detecting torque transmitted by a shaft, comprising a torsion element 11, two encoders 29, 30 connected angularly to opposite ends of the flexible element in torsion, a sensor assembly, and an electronic circuit board 14 supporting the sensor assembly generating a signal representative of the torque exerted on the shaft.

Abstract: System for detecting angular position of a rotating element with respect to a non-rotating element, comprising an annular coder provided with a number P of poles greater than or equal to 2 intended to be fixed to one of the rotating or non-rotating elements and a number N of sensors, with N greater than or equal to 3, that are able to receive a signal originating from the coder and are mounted angularly distributed on the other of the rotating or non-rotating elements facing said rotating or non-rotating element and at least one subtraction module capable of processing at least two output signals from the sensors so as to generate a differential signal.

Abstract: Instrumented rolling bearing device for measuring the rotation parameters of the bearing, including a rotating race, a non-rotating race, at least one row of rolling elements placed between the non-rotating and rotating races, a rotating coder and a pliable non-rotating electronic circuit board comprising at least one sensor and at least one flat folded zone supporting the said sensor and pressing on a rigid reference surface forming part of a sensor block, at least one sensor being in the form of a spot-type detector cell.

Abstract: A suspension thrust bearing device includes a rolling bearing provided with two races and with rolling elements arranged between the races, and two caps each in contact with one race, one of the caps including a circular flange and the other cap including an axial portion provided with hooks intended for latching onto the said flange, which hooks leave an axial space of height b remaining between the said hooks and the said flange, one of the caps including an operational part provided with a chamfer intended to facilitate latching with the other cap, with an axial surface of height a and of diameter D and with a radial retention surface, and the other cap including an operational part provided with a chamfer intended to facilitate latching, with an axial surface of height c and with a radial retention surface, the sum of the heights a+b+c being greater than 1.9% of the diameter D.
