RAILWAY EIGHT-AXLE TRACTION VEHICLE Russian patent published in 2006 - IPC B61F5/02 B61F3/06 B61C9/50 

FIELD: railway transport.

SUBSTANCE: invention relates to eight-axle traction vehicles, namely, to design of running gears, traction force transmitting mechanism and mechanism for radial setting of wheelset axles. Railway traction vehicle has body 1, frame, two four-axle bogies 27, each consisting of two two-axle bogies interconnected by beam resting on second stages of their spring suspension. Frame of body rests on said beams through bolster suspension. Body frame is furnished with two central traction brackets 5 between which one of two-axle bogies of each four-axle bogie is arranged. Frame of each two-axle bogie 8 is hinge-connected by rigid or pliable tie-rod 25 arranged in middle vertical longitudinal plane at angle to horizontal with one of central traction bracket. Traction motors are installed with different arrangement of their suspensions. Suspensions of traction motors are hinge-connected by second ends on frames of corresponding bogies or on frame of traction vehicle. Traction vehicle is furnished with mechanism for radial setting of wheelset axle in curved sections of track.

EFFECT: reduced overall dimensions of bogie and traction vehicle, reduced dynamic loads in motion when negotiating curved sections of track, reduced cross displacements and loads on springs of spring suspensions in curved sections, provision of radial setting of wheelset axles, reduced wear of wheel tires.
