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.

Claim 1
Independent Claim
221 words
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.
Claim 2
Dependent Claim
221 words
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.
Claim 3
Dependent Claim
66 words
A force measuring hub as defined in claim 1, wherein said first and second annular components are in a coaxial, adjoining relationship with respect to one another and further wherein each said mounting projection of said second annular component is secured to a respective said extension of said first annular component; the securement between said first and second annular components being comprised in said connecting means.
Claim 4
Dependent Claim
45 words
A force measuring hub as defined in claim 1, wherein each said radial web is situated at a circumferentially measured distance from adjoining said extensions; said distance being reduced to zero upon exceeding a predetermined magnitude of deformation of said radial webs and said extensions.
