Abstract: A railway axle assembly with orientable wheels (8) is compensated in width when passing on a railway track curve. The assembly comprises side beams (5,5') articulated to the opposing ends of a telescoping axle (4). The side beams (5,5') are coupled to each other by at least one connecting rod device comprised of at least one broken rod (13) hinged at a breaking point to a lever-relay (15,25) carried by the axle (4) so as to entrain the breaking point in an angular displacement of an arc of a circle in a direction opposite to that of the beams (5,5') in order to compensate for the width loss of the axle when taking curves.

Abstract: A supporting and guiding device for railway vehicles has at least four wheels 1, 2 mounted on a support intended to be fixed to the body 3 of a vehicle near one end thereof. The device includes a cross bar 8 maintained perpendicular to the vertical plane containing the longitudinal axis of the vehicle, and two longitudinal beams 5 which each carry at least two wheels. In use the beams extend longitudinally of the body on both sides of the vertical plane, and they are connected to each other by a rod 12 mounted on ball and socket joints 13.The longitudinal beams are hinged (9) to the common cross bar such that the wheels carried by the beams may become oriented in order to follow the curves of the track rails 6 and to be moved in order to pass over inequalities or unevennesses of said track.
