ABSTRACT:
Installation for measuring the wheel offset of railway vehicles. It makes it possible to obtain three circumferential profiles of the zone of contact of the running tread of said wheels as the railway vehicles travel at low speed over the installation. Once the data have been processed by computer equipment, the offset and the shape error are detected in real time. The installation is made up of equipment, at the foot of the track, formed by a running support with its guard rail, wheel-position sensors, a system for picking up radial displacements and an electronic control system. This system transmits the data to computer equipment where the process is carried out and the statistics generated and in which the results are displayed and stored.
