Abstract
An installation for the automatic evaluation of the condition of the rolling band on wheels of moving trains. It comprises a rail beam (1) for each railway line (8), a guard-rail to assure wheel guidance, feelers (P1, P2, P3, P4) intended to come into contact with the wheels passing over them, feeler holders fitted on the rail beam, to ensure wheel-feeler contact, ultrasonics equipment (12) to transmit ultrasonic pulses towards the wheels and to generate the corresponding ultrasonic plots, a local processor (13) to control the ultrasonics equipment and to receive the ultrasonic plot signals generated, a computer (14) connected to the local processor to manage the ultrasonics equipment, and an antenna (15) connected to the computer to identify the compositions of train measurements. The invention is useful to detect cracks in the rolling band of railway vehicle wheels.
