Abstract
Disclosed is a bolster of a bogie, wherein a secondary suspension connected with a transverse beam of the bogie is arranged below the bolster, and a third suspension connected with a vehicle body is arranged above the bolster. The bolster of the bogie of the present invention realize a functional separation by adding a suspension between the bottome of the bolster and the transverse beam to make the frame and the vehicle body be connected through a two-stage suspension, so that the third suspension above the bolster is only used to undertake a transverse displacement function, and the secondary suspension under the bolster is only used to undertake a rotation function, thereby further increasing displacement and relative rotation angle between the vehicle body and the bogie when the vehicle passes through a curve, and improving curve passing capability of the vehicle.
