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.
