Force measuring hub
First Claim
1. 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.

Abstract
A force measuring hub for a wheel supported on a carrier has a first annular component adapted for a coaxial attachment to the wheel and provided with a plurality of radial webs having elongation-sensing strips and a second annular component adapted for a coaxial attachment to the carrier and being operatively coupled to the first annular component such that the radial webs lie in a force path passing between the wheel and the carrier. The first annular component is a flat disc comprising an inner zone adapted to be secured to the wheel and an outer rim surrounding the inner zone. The radial webs are arranged in a single plane between the inner zone and the outer rim. The first annular component further has a plurality of extensions attached to the outer rim and oriented radially inwardly therefrom. The extensions are located in the above-noted single plane in respective spaces defined between adjoining radial webs. Each extension terminates at a clearance from the inner zone. The second annular component is also disc-shaped and includes mounting projections extending into respective clearances between the inner zone and the respective extension of the first annular component.
