RAILWAY TRACTION VEHICLE WITH TWO-AXLE BOGIES Russian patent published in 2006 - IPC B61C9/50 B61F5/38 

FIELD: railway transport.

SUBSTANCE: invention relates to design of locomotive running gear, mechanism for transmission of traction force and radial setting of wheelset axles. Proposed traction vehicle has frame or body with automatic couplers, two-axle bogies with wheelset axle radial setting mechanism. Traction electric motors 16 are mounted on axles of each bogie in series, with displacement relative to wheelsets towards middle of traction vehicle or towards near automatic coupler. One traction motor or two traction motors of each bogie are hinge-connected with frame of railway traction vehicle body by second ends of swinging suspensions 17. Cross beams 12 connecting sides 11 of bogie frames between axis are furnished with traction force transmission pivot devices 13 hinge connected to provided possibility of rotation relative to three axes and cross and vertical displacement of bogie with frame of body of traction vehicle by means of connecting pivots.

EFFECT: reduced overall dimensions of bogies, reduced dynamic loads, simplified design of bogie frames, traction force transmission and wheelset axle radial setting mechanisms.
