| 摘要 |
The present invention relates to a force transducer (101) for measuring compression and/or tension forces, that comprises a rod-shaped deformation body (102) with at least a front side (103), a rear side, a left side (105), a right side (106), an upper end face (107) and a lower end face (108) as well as at least four strain transducers (117, 118, 119), that are applied on the deformation body (102) and configured and set-up for measuring a longitudinal strain and a transverse strain of the deformation body (102). A front elongate recess (109) is provided on the front side (103) in the area of an intersection point (S) between a central longitudinal axis (L) and a central transverse axis (Q1) of the deformation body (102). Lying opposite the front elongate recess (109), a rear elongate recess is provided on the rear side. At least a left upper indentation (112) is provided above the central transverse axis (Q1) and a left lower indentation (113) is provided below the central transverse axis (Q1) on the left side (105). Respectively lying opposite these indentations on the left side, at least a right upper indentation (114) and a right lower indentation (115) are provided on the right side (106). An angle (α) between the central transverse axis (Q1) and a shortest connecting line (V) between the front elongate recess (109) and the left upper indentation (112) is not smaller than 17° and not larger than 29°. |
