Specifically, the middle of the side frame 810 may be provided with a slide groove in the running direction of the bogie, and the slider 870 is gap-disposed in the slide groove of the side frame so that the brake beam 860 can slide in the running direction of the bogie 800.

The foundation brake unit includes the brake shoe 840 described above, and the foundation brake unit can adopt a DAB unit integrated braking mode, and the brake requirement is realized by changing the installation position of the brake shoe 840 to match the position of the brake disc 730 on the wheel-to-axle box unit. The installation position of the brake shoe 840 corresponds to the installation position of the brake disc 730, and the structure can meet the condition that the position of the brake shoe 840 does not move along with the position of the wheel 720, so that the wide-rail standard rail conversion of the wheel set 700 can be realized by changing the installation position of the wheel set 700, and the normal operation of the bogie 800 between the wide rail and the standard rail can be realized by replacing different wheel set axle box units of the bogie 800.
In addition, on the guide frame of the side frame 810, a stop key structure is cancelled, so that the wheel pair not only can keep the original performance requirements, but also has the anti-falling function. When the bogie 800 is in wheel changing operation, the first wheel pair is detached from the suspended bogie 800 under the action of the detaching unit 300 and the supporting unit 200, the bearing saddle 820 has a risk of falling after losing the lower support, after the suspension rod 830 is additionally arranged, the risk of falling of the bearing saddle 820 after detaching the wheel pair can be eliminated, and meanwhile, the bearing saddle 820 can be temporarily fixed, so that the second wheel pair is convenient to install. Meanwhile, a catch key structure on the side frame 810 is eliminated, so that the requirement of more conveniently and rapidly changing wheels of the bogie 800 under the condition of not influencing the function of the bogie 800 can be met. Bearing saddles 820 having their centerlines in the same line form a pedestal suspension unit.
The bolster is also designed according to the standard of wide rail operation, for example, the design of a bogie 800 with a rail gauge of 1067mm is met, the requirement that the axle diameter center distance is 2036mm is met, and the center distance of two side bearings can be selected to be 1520mm at the installation position of the side bearing on the bolster.
