The invention relates to a bogie (1) that comprises: a frame (2); at least one transverse axle (4, 6) connected to the frame (2); at least one engine (10, 14) with a driving shaft (12, 16); means (18) for connecting each engine (10, 14) to the frame (2); for each engine (10, 14), at least one semi-hanging reducer (20) including an output sprocket (22) connected to an axle (4, 6), an input sprocket (24) rotatingly connected to the output sprocket (22) and a casing (26) in which the input and output sprockets (22, 24) are arranged, the casing (26) having at least a degree of freedom relative to the corresponding engine (10, 14); means (28) for the rotational coupling of each driving shaft (12, 16) to the input sprocket (24) of the corresponding reducer (20). The means (18) for connecting each engine (10, 14) to the frame (2) allow for a movement substantially corresponding to a transverse translation of said engine (10, 14) relative to the frame (2) with resonance frequency characteristics capable of reducing the yaw movement of the bogie (2). |
