Abstract
A torque sensor device includes a circular body having an annular inner flange, an annular outer flange, and a circular intermediate portion between the annular inner flange and the annular outer flange. The annular inner flange is closer to a center of the circular body than the annular outer flange. The circular intermediate portion is a continuously solid portion.
Claims19
A torque sensor device, comprising:
- a circular body having an annular inner flange, an annular outer flange, and a circular intermediate portion between the annular inner flange and the annular outer flange in a radial direction of the circular body, the circular intermediate portion has an inner sub-portion, an outer sub-portion, and a circumferential groove separating the inner sub-portion and the outer sub-portion, the annular inner flange is closer to a center of the circular body than the annular outer flange, the circular intermediate portion is a continuously solid portion, the annular inner flange and the annular outer flange lie in a same plane that is parallel to a main surface of the torque sensor device;
- and
- a plurality of measurement transducers formed in and/or on the inner sub-portion of the circular intermediate portion in a pairwise manner.
