FIELD: railway transport. ^ SUBSTANCE: invention relates to transmission system of locomotive with frame-suspended motors and traction transmission mechanisms. Proposed railway traction vehiocle has frame or body with automatic couplers and two three-axle bogies. Traction motors 17 are installed on axles of each bogie in series with displacement relative to wheelsets to middle of railway traction vehicle, or to side of near automatic coupler. Traction motor is connected by other end of swining suspension from side of middle of railway traction vehicle or near automatic coupler of each bogie through hinge-joint 19 with frame or body of railway traction vehicle. Cross beams 12 connecting bogie frame sides between axles are provided with pivot devices to transmit traction hinge-connecting bogies with frame or body of railway traction vehicle by pivots. ^ EFFECT: reduced overall dimensions of bogies and railway traction vehicle, reduced dynamic loads on traction motors and wheel-motor unit, simplified design of bogie frame and traction transmission mechanism. ^ 5 cl, 6 dwg |
