Abstract
Disclosed is an assembly formed by a drive shaft for a vehicle and a sensor for measuring the value of a torque applied to the shaft, the sensor including a unit for generating a magnetic field and an arrangement formed by a first coil, a second coil, a third coil and a fourth coil arranged side-by-side between a first toothed wheel of the shaft and a second toothed wheel of the shaft, parallel to the first toothed wheel and to the second toothed wheel, arranged to be immersed in the magnetic field, the overall length of the first coil, of the second coil, of the third coil and of the fourth coil being equal to the period of the first toothed wheel and of the second toothed wheel.
