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.
