Abstract: A device for measuring forces and torque in different directions. The device includes a rigid, round hub and an annular flange that is disposed parallel to the hub. The flange and the hub are connected to one another via four spokes that are arranged in the shape of a cross. The spokes are deformed by a load due to their dimensions. Such a deformation is measured with the aid of elongation-measuring strips, with the hub and flange remaining rigid. The inner ends of the spokes are secured in the hub, while the outer ends are secured to the flange via thin members, the thickness and diameter of which are such that the members yield readily in response to transverse forces and torsion of the spokes about their axes, while tangential displacements are substantially eliminated. The diameter of each member is at least 2.5 times as great as the diameter of the spokes, and the thickness of a given member has an upper limit.

Abstract: To prevent friction forces from falsifying output readings obtained upon lication of load between a base plate (1) and a load support plate (2), the base plate and the load support plate are rigidly connected by posts extending from one of the plates to an intermediate coupling element (3) and spokes extending from the coupling element (3) to the other one of the plates, bending deformation strain gauges being applied to the spokes and to the posts, respectively, so that forces applied in any direction will cause bending deformation of the spokes and posts, respectively, which can be evaluated with respect to the applied force.
