HIGH-SPEED RAIL VEHICLE BOGIE

摘要

FIELD: railway transport. SUBSTANCE: proposed device contains bogie with wheels arranged in relatively perpendicular planes and in contact with one rail. Faces of wheels are in contact with each other, each wheel rests through its cylindrical roll surface of corresponding roll surface of tetrahedral head of rail. Wheel flanges enclosing tetrahedral rail from below and wheel roll surfaces form longitudinally movable nonsplit connection with rail to prevent derailment. Carrying beams of bogie are flexibly connected with carrying beams of similar bogie moving along parallel rail with possibility of forming common four-wheeled bogie flexibly connected with running gear. EFFECT: prevention of derailment at high speed, reduced wear of rails and wheels of train. 5 dwg
