An axle box device for supporting an eddy current braking mechanism for a railway vehicle relates to the technical field of axle box devices for bogies of railway vehicles. The axle box device comprises an axle box rotating arm, an axle box rotating arm hoop, a corrugated pipe, a sealing gasket, an end cover, a lower base plate and a side base plate. The rectangular bracket on the lower portion of the axle box rotating arm hoop has enough space to support and position a bearing arm of the eddy current braking mechanism so as to solve the vertical bearing problem of the eddy current braking mechanism in the working state. Meanwhile, the bottom face and the side vertical face of the inner cavity of the rectangular bracket are buffered and limited through non-metal abrasion base plates, vertical impact of a bearing arm of the eddy current braking mechanism is relieved, and transverse displacement of the eddy current braking mechanism is limited; the two ends of the rectangular bracket are sealed through the corrugated pipes and the sealing gaskets respectively, and the sealing effect on the bearing arm of the eddy current braking mechanism is achieved. The triangular rib plates are fixedly connected to the outer walls of the rectangular brackets, and the requirement for the structural strength of the axle box device is met.
一种轨道车辆用支撑涡流制动机构的轴箱装置涉及轨道车辆转向架轴箱装置技术领域,该装置包括轴箱转臂、轴箱转臂箍、波纹管、密封垫、端盖、下垫板和侧垫板。轴箱转臂箍下部的矩形托座有足够空间对涡流制动机构的承载臂进行支撑和定位,以解决工作状态下涡流制动机构的垂向承载问题;同时,在矩形托座内腔的底面、侧立面三个面采用非金属磨耗垫板进行缓冲及限位,缓解了涡流制动机构承载臂的垂向冲击以及限制了涡流制动机构的横向位移;矩形托座的两端分别采用波纹管及密封垫的形式进行密封,实现了对涡流制动机构承载臂的密封效果;矩形托座的外壁固连有三角形筋板,满足了轴箱装置的结构强度要求。
