Beneficial effects of the present invention：
The mating vertical bogey in a kind of ground suitable for gauge-changeable bogie of the present invention is carried suitable for axle box
Gauge-changeable bogie ground corollary apparatus in, it is caused to have the beneficial effect that：
The carrying rolling element radial dimension of the present invention is smaller, and bearing capacity is strong, so as to reduce under axle box or axle box
The size for carrying boots reduces the unsprung mass of gauge-changeable bogie, improves bogie riding quality；
The vertical bogey lateral dimension of the present invention is small, leaves space for arrangement other structures in transverse direction, is easy to whole
The arrangement and function of body equipment are realized；
Vertical bearing capacity big requirement when the vertical bogey of the present invention can not only meet gauge changing, and structure letter
Single, good rigidity, manufacturing cost is low and convenient for safeguarding, similarly has reference value to other industry load bearing equipments；
