A railway vehicle with a variable trim carbody (B) having a pantograph (P) whose support (1) is movable in a transverse direction on opposite sides relative to a central position corresponding to a non-tilted condition of the carbody (B). The support (1) of the pantograph (P) is connected to the roof (R) of the carbody (B) through a first, a second and a third pivot pin (11, 15, 16) to which a first, a second and a third swinging arm (13, 19, 20) are respectively pivoted, which in turn are connected to the support (1) of the pantograph (P) by means of a first, a second and a third ball joint (14, 21, 22), respectively. The first pivot pin (11) is positioned vertically in correspondence of the center line of the carbody (B), and the second and third pivot pins (15, 16) are symmetrically arranged on opposite sides of the center line of the carbody (B) and are inclined with respect to the vertical so as to be mutually converging downwardly. The first swinging arm (13) is driven by the tilt beam (T) of a vehicle bogie (C) through a transmission (28a, 28b) placed on one side of the carbody (B). <IMAGE> |
