摘要： 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.

摘要： A tractor bogie with an integral gauge-change system which includes two frames which support sets of running gear and have sliding and centering blocks to support the bogie and unweight the wheels as they pass through a gauge changer; a toothed extendible axle arranged between each pair of sets of running gear; and a pinion/ring-gear transmission set fitted on the bogie frame to transmit the traction moment to the extendible axle. The invention is applicable to rolling stock adapted to run on tracks having two gauges.

摘要： Railway axle assembly furnished with automatic change of track gauge and adaptable to conventional freight bogies. It comprises two independent rolling element assemblies (2), each composed of a wheel, a semiaxle, an outer bearing and an inner bearing, the inner bearing carrying a locking catch with two vertical shafts connected together by a bridge which contains the pieces which facilitate its unlocking and subsequent locking. It also includes an axle frame (1) on which are mounted the rolling elements (2) and their locking systems, a device (3) for connecting between the rolling elements, two trusses (4) for translating the brake shoes, a system of electrical continuity between wheels and a device (6) for detecting hot inner bearings. The invention is useful for converting current bogies with fixed axles into bogies with transversely displaceable axles.

摘要： Device for transmitting a temperature signal by mechanical means, which consists in the use of a thermostatic element (1) made from expandable material which, when the inner bearing heats up, pushes against a rod (2) secured to a disc-carrying piece (3) and, simultaneously, to a disc (4), which, if the temperature is sufficiently high, is displaced until it comes into contact with the outer cover (5) of the bearing mounted on the other side of the wheel, that is to say on the outside, and the higher the temperature reached by the inner bearing, the greater will be the pressure exerted by the disc (4) on the cover (5) and the more rapidly the threshold detection temperature will rise, which temperature will be picked up by the pick-up device located on the track. (FIG. 1)
