Abstract
A device for measuring torques, especially for reduction gearing for activating a functional member of a motor vehicle, of the type including an electric motor (1) with permanent magnets, the output shaft (2) of which is connected to a worm (3) associated with a wheel (4), itself connected through means forming an elastically deformable damper (5) to an output member (6) of the reduction gearing, is characterized in that it includes means (9, 10) for determining angular displacements of the wheel and of the output member, these means being connected to means (8) for determining the resistive torques applied to this output member on the basis of the relative angular displacement between the wheel and the member.
