The invention provides a variable gauge braking device, a variable gauge conversion frame and a locomotive, and relates to the technical field of locomotive production and manufacturing. The gauge-changeable conversion frame comprises a framework; the gauge-changeable wheel set is arranged on the framework, the gauge-changeable wheel set comprises an axle and wheels, the axle is arranged on the two oppositely-arranged wheels in a penetrating mode, and the gauge between the two wheels in the axial direction of the axle is adjustable; the gauge-changeable braking device is fixedly arranged on the framework and located on the outer side of the gauge-changeable wheel set; when the gauge-changeable wheel set is in different gauge states, the gauge-changeable braking device is configured to be capable of abutting against the rim of the wheel and used for braking the gauge-changeable wheel set. When the gauge-changeable wheel set is in different gauge states, the gauge-changeable braking device is configured to abut against the rim of the wheel, when the gauge of the locomotive changes, the gauge-changeable braking device does not need to be changed, the braking applying and relieving function after the gauge changes can be achieved, and the efficiency of the locomotive passing through different gauges is improved.

    本发明提供一种变轨距制动装置、变轨距转换架及机车,涉及机车生产制造技术领域。该变轨距转换架包括:构架;变轨距轮对,设置于构架上,变轨距轮对包括车轴和车轮,车轴分别穿设于两个相对设置的车轮,两个车轮之间沿车轴轴向方向的轨距可调;变轨距制动装置,固定设置于构架上并位于变轨距轮对的外侧;其中,在变轨距轮对处于不同轨距状态时,变轨距制动装置被配置为能够抵接于车轮的轮缘,用于变轨距轮对的制动。在变轨距轮对处于不同轨距状态时,变轨距制动装置被配置为能够抵接于车轮的轮缘,当机车的轨距变化时,变轨距制动装置无需进行变化,即可实现轨距变化后的制动施加与缓解功能,提高机车通过不同轨距的效率。
