The invention discloses a meter-gauge motor train unit motor train bogie frame. The meter-gauge motor train unit motor train bogie frame comprises two cross beams, two side beams, an air spring mounting base, a gear box lifting base assembly, a motor lifting base assembly and a brake cylinder lifting base, and is characterized in that the two cross beams of the structure extend to the outer sides of the side beams to form outer cantilever structures; an attached air chamber is arranged on each of the extended cross beam and is the same high as the side beams; the air spring mounting base is arranged on each side beam and each attached air chamber; the end parts of the two side beams extend and droop to mount the brake cylinder lifting base. Compared with the standard gauge bogie frame, the meter-gauge motor train unit motor train bogie frame has greater improvement that the transverse span of a secondary suspension is widened, the outer cantilever structures formed by the cross beams of the structure are prolonged, and the transverse span of the air spring mounting base is widened; under space limitation, a basic brake system cannot be arranged in the structure, so that the end part of the structure extends and droops to the side beams to mount the brake cylinder lifting base; the improvement satisfies the requirements on dynamic performance, strength and service life during operation of a train, and meanwhile, the requirement that interference cannot be caused between every two parts in an operation process is met.
