The invention discloses a bullet train steering frame of a meter gauge motor train unit. The bullet train steering frame comprises a framework assembly, a wheel set and journal box device, a secondary suspension system, a central traction device, a foundation brake gear and a driving device, wherein two beams in the framework assembly are extended outside a side beam to form an external cantilever structure, a longitudinal beam is arranged above the extended beam and has the same height as the side beam, and a secondary air spring is installed on the side beam and the longitudinal beam so that the transverse span of the secondary air spring soleplate is increased; the end parts of said two side beams are extended and drooped, and provided with an end beam which is used as an installing lifting base of a brake apparatus. The bullet train steering frame is characterized in that the transverse span of the secondary suspension system is widened, so that the beam of the framework is lengthened to form the external cantilever structure and the transverse span of the secondary air spring soleplate is increased. A foundation brake system cannot be arranged at the centre of the framework due to space limitation, thus the side beam is lengthened and drooped on the framework end part which is provided with the end beam as the installing lifting base of the brake apparatus. Said improvement meets dynamic performance, intensity and service life requirements when the bullet train operates, meanwhile, various parts have no interference in an operating process.
