Proposed running gear of locomotive has body with automatic couplers and two bogies furnished with traction motors, wheelsets, two-side traction gear trains and all-welded frames. Frames of bogies are made semi-open in which end cross beams are provided with brackets in middle part and arranged under body opposite to each other. Inclined rods are connected with central part of body frame, and cross middle beams are provided with central hole in which safety pivot secured on body frame is installed with guaranteed clearance. Longitudinal sides of frame of each bogie are coupled with axle box cases through vertical vibration dampers and they rest on axle boxes through set of axle box springs. Springs are provided with vertical displacement limiters from inside and are connected in horizontal direction by one-side axle box links with elastic spherical members.
EFFECT: improved operation reliability of locomotive by improving its dynamic characteristics.
