The invention discloses a bogie frame for an intercity motor train unit trailer, and relates to the technical field of intercity motor train unit bogie frames. The frame is an H-shaped welding framework and comprises two side beams, two crossbeam steel tubes, two longitudinal beams, two braking beam steel tubes and six braking lifting sockets. Each side beam is of a box-type structure welded through steel plates, and the side beams and the crossbeam steel tubes are installed and welded through transition forge pieces with the variable cross sections. The lower portions of the longitudinal beams stretch across the two crossbeam steel tubes, the ends of the longitudinal beams and the braking beam steel tubes are docked, installed and welded so that a rectangular structure can be formed, and an upper cover plate of the longitudinal beams is composed of a transverse backstop base and two cover plate bodies which are integrally forged; the braking lifting sockets are of an integrally forged structure, and the braking lifting sockets and the braking beam steel tubes are connected into a whole in installing and welding modes. According to the frame, the braking lifting sockets and the longitudinal beams form a whole, the design structure is simple, braking force can be better transmitted, and the welding quantity is small compared with an existing frame. The transverse side beams are connected through a middle transition forge piece with the variable cross section, stress at the connecting position of the transverse side beams is greatly reduced, the phenomenon of stress concentration is avoided, and the structural strength is improved.
