Abstract (en)

[origin: EP0942100A2] A wheel translation control system in track gauge changers comprising load cells (C1, C2, C3) fitted in elastic sensing devices (9), housed in unlocking guides (5, 6) and joined to transverse translation guides (7, 8), summing junction boxes connected to said load cells to receive the signals generated by the latter when the wheel sets pass, a signal conditioning unit connected to said junction boxes to condition the analogical signals transmitted from the latter, and a digital equipment to process and store the signals received from the load cells and other data referring to the vehicle and its wheel sets. The invention is useful to detect anomalous translation behaviour of one or more wheels on passing from one track gauge to another. <IMAGE>
