First Claim
Patent Images
1. A system for measuring wear of a wheel on a moving vehicle comprising in combination:
- first means for providing a signal V1 indicative of the measurement of the actual velocity of said vehicle independent of wheel motion;
second means of providing a signal V2 indicative of revolutions per unit time of said wheel; and
means responsive to signals V1 and V2 for determining the difference between V1 and V2 at time spaced points at at least one value of V1 to determine therefrom wear of said wheel.

Abstract
A system for measuring wheel wear of a railroad vehicle includes a first speed measuring device, such as a microwave doppler speed sensor for measuring speed of the vehicle independent of wheel rotation rate, a second speed measuring device for measuring vehicle speed in terms of wheel rotation rate and a comparison device for measuring the difference of the two speed signals over time to therefore provide a signal indicative of wheel wear.
