Force sensor system (10) for measuring an external force (f) according to the shearing principle, wherein the force (f) substantially radially from the outside, transversely with respect to a longitudinal axis (18) of the kraftaufnehmerystems (10), wherein the force sensor system (10) comprises: a radially inwardly positioned stud element (12); an axially outside the support member (16) which can be positioned, which is arranged exclusively with the stud element (12) to be fixedly connected; and a sleeve body (14), of the: in a sleeve-like manner, to the coaxial receiving the bolt body (12) is formed; extends coaxially to the longitudinal axis (18); and the radially outward direction to the stud element (12) is positionable sitting; wherein the sleeve body (14) comprises: at least one axially externally disposed first section (28) for the radial introduction of force (f) via an external force introduction member (24) of an external machine (20), in which the force measuring axis (10) is inserted, and the force (f) is to be measured, wherein the external force introduction member (24) the radially outward direction to each of the first portions (28) is seated and wherein the first portion (28) radially to the stud element (12) is spaced apart; at least a second portion (30) for measuring the force (f) for receiving at least one measuring cell (36) is set up and of the radially inner and / or on the outside of the peripherally extending groove (34), wherein the sleeve body (14) at least also in an axially outer end of the second section (30) to the stud element (12) is at a distance; and at least a third section (32), which: is located axially inward; axially on the inside against the at least a second portion (30); and radially on the stud element (12) is seated; and wherein, in a in the external machine (20) is installed and assembled state of the force sensor system (10) the force (f): from the outside via the external force introduction member (24) (radially, exclusively) in each of the first portions (28) of the force sensor system (10) is introduced; in a normal operation of the force sensor system (10) by each of the second sections (30) in the third section (32) and from there via the bolt body (12) into the support body (16) is passed to the force sensor system (10) by means of a machine frame (22) of the external machine (20) to leave, wherein the machine frame (22) on the at least one support body (16) is seated; and in an overload operation the first section (28) is deformed, so that each of the first portions (28) radially on the stud element (12) and / or axially to said at least one support body (16) abuts,n="29" as a result of which the force (f) each of the second portions (20) out, directly from each of the first portions (28) in the bolt body (12) and / or the or the support body (16) is guided and the force sensor system (10) via the final or the support body (16) leaves.
