The utility model discloses a bogie braking device with a flexible fulcrum, belonging to the mechanical field of railway wagons. The bogie braking device comprises a fixed lever fulcrum base, a fixed lever, a braking beam and a floating lever, as well as a fixed lever fulcrum, a chain shoe ring and a connecting piece, wherein the chain shoe ring and the fixed lever fulcrum are connected between the fixed lever fulcrum base and the fixed lever by the connecting piece. Through adoption of the bogie braking device, the brake bar system torsion (distortion) caused by vertical motion of a swing bolster can be avoided; the phenomena that the wheel edge of a single side wheel in a wheel pair is normally abraded and the pedaled surface of the single side wheel is scratched, caused when a brake shoe deviates to the wheel edge of a wheel, can be eliminated; the braking leverage and braking efficiency of a bogie braking system are not changed and other structures of a bogie are changed unnecessarily, which facilitates t
