Abstract
Abstract A joint for connecting a drive unit to a measuring arrangement connected to a wheel. The measuring arrangement comprising a wheel shaft rotatably supported by a measuring hub having deformable beams for measuring moments and forces acting on the wheel and the joint comprising a diaphragm flexible in the axial direction but rigid in the peripheral direction connected between the wheel shaft and one end of a cylindrical tube which is radially resilient and axially rigid, the other end of the tube being coupled to the drive unit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
95 words
A homo-kinetic joint interconnecting a measuring arrangement and a drive unit, said measuring arrangement comprising a wheel shaft rotatably supported by a measuring hub that measures forces and moments acting on a wheel connected to said measuring arrangement, said joint comprising a diaphragm connected to said wheel shaft and flexible in the axial direction but rigid in a peripheral direction and a cylindrical tube coupled at one end to said diaphragm and connected at the other end to said drive unit, said tube functioning as a bar spring which, while axially rigid, is radially resilient.
Claim 2
Dependent Claim
95 words
A homo-kinetic joint interconnecting a measuring arrangement and a drive unit, said measuring arrangement comprising a wheel shaft rotatably supported by a measuring hub that measures forces and moments acting on a wheel connected to said measuring arrangement, said joint comprising a diaphragm connected to said wheel shaft and flexible in the axial direction but rigid in a peripheral direction and a cylindrical tube coupled at one end to said diaphragm and connected at the other end to said drive unit, said tube functioning as a bar spring which, while axially rigid, is radially resilient.
Claim 3
Dependent Claim
42 words
A joint according to claim 1 wherein said drive unit comprises a synchronizing displacement joint and said other end of the cylindrical tube is connected thereto and the outer edge of the diaphragm is fixed to a flange of said wheel shaft.
