Abstract
A multicomponent measuring capable of measuring strains wheel having a hub, a rim, and a measuring element arranged between the hub and the rim and having strain gauges. The measuring element is a one-piece element and has an axis of rotation substantially parallel to the axis of rotation of the multicomponent measuring wheel.
Claims14
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.
