Force measuring hub

In a force measuring hub for measuring forces and/or torques acting in at least the circumferential direction of a wheel-like body supported on a carrier, the force measuring hub including a first annular component adapted for a coaxial attachment to the wheel-like body;

• the first annular component further having a plurality of radial webs provided with elongation-sensing strips;
• a second annular component adapted for a coaxial attachment to the carrier;
• connecting means for operatively coupling the second annular component and the first annular component such that the radial webs lie in a force path passing between the wheel-like body and the carrier;
• the improvement wherein said first annular component is a flat disc comprising an inner zone adapted to be secured to the wheel-like body and an outer rim surrounding said inner zone;
• said radial webs being arranged in a single plane between said inner zone and said outer rim;
• said first annular component further comprising a plurality of extensions attached to said outer rim and oriented radially inwardly therefrom in said single plane into respective spaces defined between adjoining said radial webs;
• each said extension terminating at a clearance from said inner zone;
• said second annular component being disc-shaped and including mounting projections extending into respective clearances between said inner zone and the respective extension of said first annular component.
