THREE-AXLE BOGIE WITH RADIALLY ADJUSTABLE WHEELSETS Russian patent published in 2002 - IPC

FIELD: railway transport. SUBSTANCE: bogie has extreme wheelsets coupled by longitudinal carriers with cross guide balance arms hinge secured on frame cross beams. Bogie has articulated lever mechanisms arranged at both sides of bogie which are provided with longitudinal tie rods. Said tie rods connect ends of cross guides of balance arms with vertical bell cranks by means of hinge joints. Hydraulic damper is connected to one of arms of vertical lever at each side of bogie. Second end damper is hinge-connected to frame. Frame of bogie rests on axle box springs through knife joints. Hinge joints of extreme wheelsets are directed square to longitudinal axis of bogie, and those of middle wheelset, are parallel to bogie.
