Abstract:
A measuring wheel for measuring strains having an axis of rotation comprising:a rim; a hub; a one-piece measuring element disposed between the rim and the hub, the measuring element being substantially rotationally symmetric with respect to the axis of rotation of the measuring wheel; and a strain gauge arrangement disposed on the measuring element capable of determining at least an axial strain and a radial strain of the measuring element; wherein the measuring element includes: a first annular flange attached to the rim and extending substantially radially; a tubular section adjoining the first annular flange at a radially inward section of the first annular flange, the tubular section extending substantially axially; an intermediate flange adjoining the tubular section at a radially inward part of the tubular section; an annular region adjoining the intermediate flange at a radially inward portion of the intermediate flange; and a second annular flange adjoining the annular region at a radially inward area and connected to the hub.
