LOCOMOTIVE BOGIE (VERSIONS) Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to diesel locomotives and electric locomotives, particularly, to design of devices for providing radial setting of wheelset axles on curved sections of track. Novelty is that axle boxes of first wheelset are hinge-connected with lower ends of double-arm levers. Upper ends of double-arm levers are connected with frame or body of locomotive, and their middle part is connected with frame of bogie. Axle boxes of last wheelset are hinge-connected with middle part of double-arm levers whose upper ends are connected with frame or body of locomotive, and lower ends, with frame of bogie. As a version, axle boxes of last wheelset can be hinge-connected with lower ends of double-arm levers whose middle part is hinge-connected with frame of bogie, and upper ends are connected with additional double-arm levers. Additional double-arm levers are hinge-connected by their middle part with frame of bogie, and by second ends, with frame or body of locomotive. Invention provides automatic setting of wheelset axles when negotiating curved sections of track side pressure of wheel flanges on rail side dynamic loads and decreases resistance to movement in curve and wear of wheels and ails. EFFECT: reduced wear of wheels and rails. 4 cl, 6 dwg
