The invention relates to the technical field of high-speed railway bullet trains, in particular to a high-speed railway bullet train bogie. A sliding block transversely slides on a guide rail, so that a protection box transversely slides on the guide rail, and the protection box can be mounted or dismounted below a framework; the protection box transversely slides below the framework, so that an electric heater in the protection box transversely slides below the framework; fixing bolts are screwed on a protection cover and the protection box, so that the protection cover is fixed on the protection box, and the protection cover can seal the protection box; and the protection box is sealed through the protection cover, so that the electric heater is protected by the protection box and the protection cover, and the situation that the electric heater is damaged due to the fact that sundries such as pebbles make direct contact with the electric heater in the running process of the high-speed railway bullet train bogie is avoided.
本发明涉及高铁动车技术领域,具体涉及一种高铁动车转向架,通过滑块在导轨上横向滑动,从而使得保护盒在导轨上横向滑动,进而使得保护盒可在构架下方进行安装或拆卸,通过保护盒在构架下方横向滑动,从而使得保护盒内的电热器在构架下方横向滑动,通过固定螺栓在防护盖与保护盒上进行旋紧,从而使得防护盖在保护盒上的位置进行固定,进而使得防护盖可将保护盒进行密封,通过防护盖将保护盒进行密封,从而使得保护盒与防护盖对电热器进行了保护,进而避免了在高铁动车转向架运行过程中石子等杂物与电热器直接接触会造成电热器损坏的情况。
