The device for varying the gauge of railway vehicles provided with independent wheels makes it possible to use said vehicles on tracks of different gauge, making it possible for the wheels to be able to undergo a displacement in the direction of their axles in order to adapt them to the relevant gauges. To this end, the wheels, which are independent, are arranged mounted on displaceable hubs, transverse movement of which is obtained by means of a pusher which may be actuated, without distinction, by pneumatic or hydraulic pressure cylinders or rods. <IMAGE>
