<p>A steering bogie (1) is rotatable with respect to the vehicle chassis (4) about a first substantially vertical axis (3) and the device comprises: a bar (16) fixed to this chassis and the axis of which is parallel to the longitudinal axis of the chassis itself, a plate (17) rotatable with respect to the bogie about a second vertical axis (18) and which is pivoted to a steering mechanism control rod (9) and is connected in an articulated manner to one end of the said bar; the pivot axis (22) between the plate and the said control rod and the connection axis (33) between the plate and the end of the bar are located on opposite sides of the vertical axis (18) of the bogey and are substantially disposed in the same plane as that which contains the said axis; the articulated connection between the end of the bar (16) and the plate (17) is achieved with articulation means (26, 27) which allow the plate to turn with spherical motion with respect to the said end of the bar and, simultaneously, allow the plate itself to displace with respect to the bar in the first-defined plane.</p> |
