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.

A supporting and guiding device for a railway vehicle, comprising: (a) a cross bar (8) disposed transverse to a longitudinal axis (X－X′) of a railway vehicle, (b) a pair of spaced longitudinal beams (5), (c) a pair of track engaging wheels (1, 2) individually and rotatably mounted to opposite ends of each beam, (d) a transversely oriented rod member (12), (e) a first pair of ball and socket joints (13) individually connecting opposite ends of the rod member between and to the beams at one end thereof, (f) a pair of pivotable hinge means (9) carried by the cross bar individually mounting the beams to the cross bar intermediate the ends of the beams, (g) a transversely oriented, elongate swivel bar (16), (h) a second pair of ball and socket joints (15) individually connecting opposite ends of the swivel bar to lower sides of the beams below the hinge means, and (i) vertical pivot means (17) connecting a mid-point of the swivel bar to the cross bar, whereby the wheels may freely orient themselves to follow curvatures of the track and to pass over inequalities and unevennesses of the track.
