FIELD: railway transport.
SUBSTANCE: invention relates to eight-axle traction vehicles, namely, to design of running gear, traction force transmitting mechanism and mechanism for radial setting of wheelset axles. Railway traction vehicle has body 1, frame, two four-axle bogies consisting each, of two two-axle bogies connected by beam resting of 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 for each four-axle bogie 39 arranged in between. 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 nearest central traction bracket. Traction motors are installed with different arranged of their suspensions. Suspensions of traction motors are hinge-connected by second ends of 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 bogies and vehicle, reduced dynamic loads in motion when negotiating curved sections of track, reduced cross displacements and loads on spring of spring suspensions in curved sections, provision of radial setting of wheelset axles, reduced wear of wheel tires.
