FIELD: transport.
SUBSTANCE: claimed drive bogie comprises the frame with lengthwise thrusts, wheel drives with reduction gearboxes and thrust motors brought outside the wheels limits, disc brakes, car suspension springs, dampers and rail brakes. Wheels are arranged in the frame to run independently. Disc brake elements are arranged at reduction gearbox. Wheel drives incorporate springs engaged elastically with the bogie frame. Bogie frame can skew in vertical plane because of flexure of two extreme crosswise beams relative to the axis of central stiff crosswise beam.
EFFECT: lower unsprung bogie weight, improved contact between wheels and rails, lower dynamic load at bogie elements and track, lower noise and wheel wear, higher life of running gear.
