Claim:
1. A measuring rail, comprising: a central rail portion, including a load introduction body, extending longitudinally between a first load exit plate and a second load exit plate in a ground plane, wherein the first and second load exit plates are in contact with the ground; a first outer rail portion extending longitudinally from the first load exit plate, and opposite a first direction, from the first load exit plate towards the second load exit plate; a second outer rail portion extending longitudinally from the second load exit plate, and opposite a second direction, from the second load exit plate towards the first load exit plate; a first longitudinal slot extending from a first bore hole in the first outer rail portion and a second longitudinal slot extending from a second bore hole in the second outer rail portion of the measuring rail; at least two strain gauges disposed in two recesses, one of the recesses disposed entirely within the first outer rail portion and one of the recesses disposed entirely within the second outer rail portion; and a first deformation body rigidly connected to the first load exit plate and a second deformation body rigidly connected to the second load exit plates, wherein the first deformation body is connected to the load introduction body by a first link disposed only in the first outer portion of the measuring rail and the second deformation body is connected to the load introduction body by a second link disposed only in the second outer portion of the measuring rail, and wherein at least two strain gauges are arranged within each deformation body such that the at least two strain gauges sense shear strains acting between the link and the load exit plate.
