Multi-component measuring disc wheel

U.S. Patent Number: 5313828

Abstract: A multi-component measuring disc wheel for vehicles is provided in which an annular measuring disc is held on an auxiliary flange of the specially designed rim by means of a plurality of stud bolts parallel to the axis. The stud bolts act as measuring cross-sections and are equipped with strain gauges. The measuring disc is held at a distance from the auxiliary flange and has spoke-type measuring webs which are also equipped with strain gauges. The inner edge of the measuring disc is bolted to a pot-shaped wheel adaptor which compensates for the axial distance between the measuring disc and the normal axial position of the bolt-on flange of the wheel disc of a conventional vehicle wheel and matches in the bolt-on region the bolt-on flange of a conventional vehicle wheel disc. A signal transmission device is rotatably mounted in or on the wheel adaptor and the stationary part of the signal transmission device is fixed by means of a movable linkage which is, however, fixed in the peripheral direction. The strain gauges applied to the axial and the radial measuring cross-sections are selected in an appropriate manner as shear strain gauges or as tension/compression strain gauges and are applied in such a position in each case and with respect to their alignment and are connected into associated electrical measuring bridge circuits.
