Abstract: The articulation system relates to articulated tramway carriages comprising at least two bodies, the opposing ends of which are connected together in an articulated manner in order to maintain substantial continuity of the walking surface, and are supported by wheels at or adjacent to the articulation zone. In the articulation system, the end of each body is supported on its own axle provided with independent wheels, the opposing bodies and the relative axles being connected together by means of a drawbar, slidable connections and/or connecting rods to jointly form a bogie with a non-rigid frame. The axle is of double swanneck shape with uprights for connecting disc brakes on the outside of the wheels.
