A COMPARISON OF TEMPERATURES DEVELOPED IN WHEELS BY CAST IRON AND COMPOSITION SHOES

The purpose of these tests was to compare the heating effect of cast iron and composition shoes on railway car wheels. The temperature of the car wheels was measured while the wheel was rotating and the results were plotted. Since the composition shoe normally has a higher coefficient of friction, the temperature generated was compared to the braking energy applied to the wheel. The results indicate that the composition shoes tend to cause a higher temperature to develop in the wheel than the cast iron shoes, when comparable braking energy is applied to the wheel.
