RAIL VEHICLE BOGIE Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to design of devices aimed at provision of radial setting of wheelset axles of bogies when negotiating curved sections of track. Proposed device contains three wheelsets with axle boxes. Rods are hinge-mounted between thrust brackets of axle boxes of extreme and middle axles. Axes of rods do not intersect with axes of extreme wheelsets. Centers of longitudinal rigidity of springs of spring suspension resting on axle boxes of extreme wheelsets are displaced relative to vertical planes passing through their axes by preset value. EFFECT: reduced side pressure of wheel flanges onto rail, resistance to movement in curved section of track, wear of flanges and consumption of fuel, increased service life of wheelsets. 3 cl, 5 dwg
