Abstract
The invention relates to a twisting torque sensor, comprising a transmission shaft () subjected to the torque to be measured, a reference shaft (), and a device for measuring an angular deformation representing the torque to be measured between the two shafts. The torque sensor is characterised in that the transmission shaft () comprises a bore () extending from one end of the transmission shaft (), referred to as input () of the shaft, to an opposite end, and in that the torque sensor comprises an enclosure () for confining the temperature of the two shafts, and a fluid circulation circuit including a portion made up of said bore (), an injector () for injecting the fluid into the bore () at said input () of the shaft, and a fluid temperature sensor () in the fluid circulation circuit, the measured temperature being intended for correcting the torque measurement.
