The invention discloses a frame of bogie for an A-type broad-gauge metro vehicle. The frame comprises side beams, a cross beam and a primary spring seat. The frame is characterized in that the cross beam and the side beams of the frame are in transition connection through a connecting seat for the cross beam and side beams, and the connecting seat for the cross beam and side beams and a brake cylinder mounting seat are integrated to a whole body, an air spring assisted air cylinder on the vehicle is taken as an auxiliary chamber of the air spring. According to the frame, the side beams and the cross beam of the frame are in transition connection through the connecting seat for the cross beam and side beams, so that the adverse effect on the side beams is avoided when a steel pipe penetrates through the side beams, and furthermore, welding lines are removed from a high stress area, so that the stress condition of the frame is improved and the service life of the frame is prolonged; the air spring assisted air cylinder on the vehicle replaces the auxiliary chamber of the air spring in the side beams and the cross beam, so that the technological requirements for welding of the cross beam and the side beams are reduced; through the integrated brake cylinder mounting seat and the connecting seat for the cross beam and side beams, the number of the welding lines at the place is greatly reduced and the welding technology is improved.
