Abstract (en)

Bogies for railway vehicles with variable gap between wheels, consisting of a center frame (1), to which four oscillating arms are united by means of relative joints (2), at each of which ends bearing boxes for each rolling assemblies (3) are housed, which can be transversely moved, the wheel being located in each of two positions corresponding to two gauges, relying on the fact that the opposed portion of each arm rests on a helical spring (4), the lower end of which is resting on the center frame bottom, and at the end of this portion there is mounted a vertical shock absorber (5). <IMAGE>
