Abstract

The invention relates to a force-sensing device for measuring an axial force, said device comprising a deformation body having a force-introducing section on which the axial force to be measured acts. The deformation body deflects the axial force to be measured from the force-introducing section by means of lever sections, converting it into a radial force, said force being applied to a force-sensing section of the deformation body, in an intensified manner according to the lever ratio, in order to deform a sensor element provided inside the deformation body in a force-proportional manner.
