Meter gauge axle disc braking bullet train bogie

The invention discloses a meter gauge axle disc braking bullet train bogie. A penetrating type axle box assembly is adopted, and an axle extends outside the axle box assembly. A braking disc is installed on the part, stretching out of the axle box, of the axle. Framework side beams are of C-shaped structures, and the two ends of each side beam are each provided with a section of suspension arm type structure which extends outside the corresponding side beam in a suspending mode and used for lifting a four-point suspension type braking unit. A guide pillar type structure is adopted in a suspension device. The meter gauge axle disc braking bullet train bogie completes the installation of an axle disc type basic braking device on the meter gauge bogie, the braking thermal capacity limiting value is greatly increased exactly due to the application of the axle disc type basic braking device, and therefore the highest operation speed of trains is increased. The structure of the bogie is more compact, the length and the occupied space of the bogie are greatly reduced, and other equipment of the trains is conveniently arranged. The guide pillar type structure is adopted in the suspension device, the fixing axle distance of the bogie and the width size of the bogie are compressed to the minimum, the curve passage capability of the trains is improved, and it is ensured that the trains have the enough safe margin with the limit.
