<p>The driving bogie consists of a main chassis (1) and at least one auxiliary chassis carrying an axle (32) and linked at the end of the main chassis by means of a pivot axis (4), with vertical axis of rotation. The pivot axis of the auxiliary chassis is linked to a steering servo (71, 72), controlled by the curvature of the track compared to the angular separation between the longitudinal axes of the driving line and the main chassis.</p> |
