The invention discloses a motor car bogie structure. The motor car bogie structure comprises an H-shaped frame body. The frame body comprises two side beams and middle beams. The side beams are arcuate in shape. Each of the two ends of the side beams is provided with a positioning arm seat. Two ends of the side beams are provided with vertical damper mounting seats. The front ends of the side beams are provided with brake cylinder mounting seats. The middles of the side beams are provided with air spring mounting seats. The middle beams are located between the two side beams. The end portionsof the middle beams are welded with the side beams. The two sides of the middle beams are provided with gear box hanging rod seats and traction motor mounting seats. Openings are formed in the middlesof the middle beams. Traction drawing rod seats are arranged at two ends of the openings. The frame body is composed of the side beams and the middle beams, the middle beams and the side beams are integrally welded, and the structural strength is higher. All original equipment mounting seats are integrated on the side beams and the middle beams, so that a motor car bogie is more convenient to mount.
