The invention discloses a pantograph upper arm assembly. The pantograph upper arm assembly comprises a pantograph upper arm, a balance rod, a first connecting rod, a second connecting rod and a pantograph head rotating shaft, the pantograph upper arm comprises an upper cross pipe, an upper housing, a lower housing, a longitudinal strut, a first rotating shaft mounting seat, a second rotating shaftmounting seat, a sealing cover and a mounting plate; the upper cross pipe is of a circular pipe structure and is divided into two sections which are symmetrically welded to the left side and the right side of the upper cover shell, and the lower cover shell and the upper cover shell are connected through a fastener to form a thin-wall sealed box structure. The upper housing, the longitudinal strut, the first connecting rod, the second connecting rod and the balance rod form a pantograph upper four-connecting-rod hinge mechanism, and the first connecting rod, the second connecting rod, the balance rod, the bearing and the like are all arranged in the pantograph upper arm. The balance rod deformation or fracture failure rate caused by foreign matter striking can be reduced, the windward resistance of the upper arm is reduced, and the aerodynamic characteristics of the pantograph upper arm component are improved.
本发明公开了一种受电弓上臂组件，包括受电弓上臂、平衡杆、第一连接杆、第二连接杆、弓头转轴，所述受电弓上臂包括上交叉管、上罩壳、下罩壳、纵支柱、第一转轴安装座、第二转轴安装座、密封盖、安装板；上交叉管为圆管结构，分为两段对称焊接到上罩壳左右两侧，所述下罩壳与上罩壳通过紧固件连接形成一种薄壁密封箱体结构。上罩壳、纵支柱、第一连接杆、第二连接杆与平衡杆构成受电弓上部四连杆铰接机构，第一连接杆、第二连接杆、平衡杆、轴承等全部内置于受电弓上臂中。可以降低异物击打导致平衡杆变形或断裂故障率，减少上臂迎风阻力，改善受电弓上臂部件空气动力学特性。
