Wheel measurement

The electronic wheel profile gauge is designed for measurement of the continuous tread profile of train and tram wheels. Measurements can be performed directly on vehicles, i.e. without rolling the wheelsets out. The operator fixes the gauge to the wheel with its magnetic foot and guides the spherical measuring tip along the wheel tread. Thanks to the contact-based method, the measurement is not encumbered with errors caused by weather conditions (e.g. raindrops), grease stains or sunlight reflections. Measurement results are saved in the gauge memory capable of storing information about several thousand profiles. Preliminary evaluation of the measured profiles is possible immediately after the measurement, on the big graphic display of the gauge control panel, on which the wear-related parameters, h, e1/e2, qR are also shown.

The gauge can be used in planning of machining on underfloor lathes, for verification of the correctness of the machined profile and for recording the wheel wear progress during their operation - for maintenance services and for research.

After detaching the control panel from the gauge, one can view the measurements saved in the gauge memory and transfer them to a PC disk via a USB Pendrive. PC software allows to compare the measured profile with the reference profiles, to compare multiple measurement results obtained at different times, dimensioning profiles’ drawings, and also annotating them. This software allows the saving, visualising and printing of reports with results.

Measurement results can also be entered into an optional P&D system rolling stock wheel data management system within a transport company.
