Abstract (en)

A railway bogie (1) is described, which comprises an articulated frame (2) extending along a longitudinal axis (A) and a plurality of wheels (3) which are carried in a rotatable manner by the articulated frame (2) independently of each other to allow the movement of the railway bogie (1) on a rolling plane (P); the articulated frame (2) comprises a central sub-frame (4) which carries a first pair (3a) of wheels (3), a front sub-frame (5) which carries a second pair (3b) of wheels (3) and is carried in a movable manner by the central sub-frame (4) so as to oscillate about a first rotation axis (S<sub>1</sub>) orthogonal to the rolling plane (P), and a rear sub-frame (6) which carries a third pair (3c) of wheels (3) and is carried in a movable manner by the central sub-frame (4) so as to oscillate about a second rotation axis (S<sub>2</sub>) orthogonal to the rolling plane (P).
