Abstract
A device for measuring the torque applied to a kinematic assembly including a detection means capable of supplying a signal representative of the angular position A1 of a first element of said kinematic assembly, a detection means capable of supplying a signal representative of the angular position A2 of a second element of said kinematic assembly, a memory for storing a correction value C, and a processing unit provided with means for applying the correction value C to one of the angular positions A1 or A2, where C=A2−A1 when the torque applied to the kinematic assembly is zero.
Claims13
A device for measuring the torque applied to a kinematic assembly comprising
- a control shaft,
- a detection means capable of supplying a signal representative of the angular position Al of a first element of said kinematic assembly, and
- a detection means capable of supplying a signal representative of the angular position A2 of a second element of said kinematic assembly, one of the detection means comprising an encoder, a memory for storing a correction value C, and a processing unit provided with means for applying the correction value C to one of the angular positions A1 or A2, where C=A2−A1 when the torque applied to the kinematic assembly is zero.
A method of measuring the torque applied to a kinematic assembly comprising a control shaft, the method comprising:
- measuring, with first detection and measurement means, the angular position A1 of a first element of said kinematic assembly.
- measuring with second detection and measurement means, the angular position A2 of a second element of said kinematic assembly,
- wherein one of the first or second elements is the shaft, and
- wherein a correction value C is applied to one of the angular positions A1 or A2, where C=A2−A1 when the torque applied to the kinematic assembly is zero.
