Abstract
The flexible connection device of the invention is disposed between a flexible side beam of a bogey frame and an arm of an axle-box, and wherein the stiffness of the connection is greater in the vertical direction (Z) than in the two horizontal directions (X, Y). This enables the side beam to be decoupled from the axle-box, thereby reducing the stresses at the interfaces between these parts when the bogey frame moves transversely and vertically relative to the axles. This also presents the advantage of allowing relative displacements between the side beam and the axle-box.
