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 pairs of two-axle bogies 8 interconnected by tie-rods 27. body frame is furnished with central traction brackets 5 for each two bogies arranged in between, frame 9 of each two-axle bogie is hinge-connected by rigid or pliable tie-rod 25 arranged in middle vertical longitudinal plane at angle to horizontal with nearest traction bracket. Traction motors are installed with different arrangements 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 when negotiating curved sections of track, provision of radial setting of wheelset axles, reduced wear of wheel tires.
