PARALLELOGRAM CONNECTING ROD STRUCTURE, PARTICULARLY A MONOLITHIC PARALLELOGRAM CONNECTING ROD STRUCTURE FOR A WEIGHING SENSOR

摘要

The invention relates to a monolithic parallelogram connecting rod structure, particularly for a monolithic weighing sensor, comprising two parallelogram connecting rods (9, 11) located in parallel, wherein each of the two parallelogram connecting rods (9, 11) is connected to a rigid element (3, 7) by at least one solid body joint (13a, 13b; 15a, 15b; 17a, 17b; 19a, 19b) at each of the two ends of each parallelogram connecting rod (9, 11), the four joint axes of the solid body joints (13a, 13b; 15a, 15b; 17a, 17b; 19a, 19b) being parallel and forming the vertices of a parallelogram in cross section. According to the invention, at least one end of a parallelogram connecting rod (9, 11) is connected to the related rigid element (3, 7) by at least two solid body joints (13a, 13b; 15a, 15b; 17a, 17b; 19a, 19b), wherein the longitudinal extension planes of the solid body joints encompass a non-zero angle (α, ß), the joint axes of the at least two solid body joints (13a, 13b; 15a, 15b; 17a, 17b; 19a, 19b) being aligned. The invention further relates to a weighing sensor having such a monolithic parallelogram connecting rod structure.
