Abstract:
1. A force-sensing device comprising: a yoke having a location of force introduction for a force to be measured acting in a predetermined direction on the location of force introduction; two measuring springs each having a first end rigidly connected to the yoke and elastically deformable by the force to be measured acting on the location of force introduction; a support adapted to be rigidly connected to a machine frame; the two measuring springs each having a second end arranged on the support; first measuring means that detect and evaluate a deformation of the two measuring springs caused by the force to be measured; wherein the two measuring springs each have two longitudinal slots extending between the yoke and the support, wherein the two longitudinal slots define three bending springs that are parallel relative to one another and spaced apart from one another and are connected to the yoke in such a way that the yoke is always guided in parallel in a transverse direction that is transverse to the predetermined direction of the force to be measured; and second measuring means provided for the three bending springs, the second measuring means detecting a transverse deformation caused by a force in the transverse direction.
