An on-line automatic measuring device for rail transit vehicle wheels was introduced. This device uses segmented measurements and large and small numbers. The principle of separate measurements. When in use, the measuring device is fixed on the wheel, and the motor drives the probe to complete the swing scanning measurement along the wheel diameter. The measured value is transmitted to the host computer through sampling, and the maximum value is the diameter of the wheel. The reliability of the device was verified by experimental comparison, and the uncertainty analysis of the measurement results using the device is carried out, and the results show that the technical requirements of the standard wheelset of rail transit are fully met.
