WO 200198769 A UPAB: 20020403 NOVELTY - A linear array of ultrasonic test heads (6) are positioned on the inside of the track rail (4), adjacent the contact surface (3) of the rail cooperating with the running surface (2) of the rail vehicle wheel (1). Each test head emits ultrasonic waves which are fed to the rail vehicle wheel via the contact surface, and receives the reflected waves, with the test heads inclined at an oblique angle to the longitudinal axis of the rail. DETAILED DESCRIPTION - An INDEPENDENT CLAIM for a rail vehicle wheel testing method is also included. USE - The testing device is used for checking rail vehicle wheels for detecting fractures etc. ADVANTAGE - The device allows rapid testing of each rail vehicle wheel during its passages along the rail track.
