The bogie is a H frame consisting of two side beams and a center plate beams, which are welded together, a box type cross section is adopted. Wheel-pair axle box spring is supported in suspension through the axle box spring; the internal and the external springs with rigidity of class II are adopted with different height, double inclined wedge type axial box friction reduction is adopted. Suspension sliding type two-sides braking is used for the basic braking equipment, brake head links with the brake beam through pin shaft. The high friction brake block is used.
