The invention relates to the technical field of axle assemblies, in particular to an axle frame of a wheel-side electric drive axle, the wheel-side electric drive axle and a vehicle. The bridge frame of the wheel-side electric drive bridge comprises a main shell, the two ends of the main shell are each provided with an installation base used for installing a wheel-side mechanism, an oil storage cavity is formed in an inner cavity of the main shell, the main shell is provided with an oil way connecting structure, and the oil way connecting structure is used for being connected with a circulating oil way used for supplying oil to the wheel-side mechanism in a circulating mode. The oil storage cavity is provided with a space used for being communicated with the oil outlet end and the oil return end of the circulating oil way. The oil bottom box is formed by utilizing the shell structure of the bridge, the oil storage cavity is formed by utilizing the size of the bridge while the normal bearing function of the bridge is ensured, the structure is compact, the space is saved, the influence on the ground clearance caused by arranging the oil bottom box at the bottom of the motor of the wheel side mechanism can be avoided, and the low floor of a vehicle can be realized.

    本发明涉及车轴总成技术领域,具体涉及一种轮边电驱桥的桥架及轮边电驱桥、车辆。轮边电驱桥的桥架包括主壳体,主壳体两端分别设有用于安装轮边机构的安装座,主壳体内腔形成储油腔,主壳体设有油路连接结构,油路连接结构用于连接对轮边机构进行循环供油的循环油路,储油腔具有用于与所述循环油路的出油端和回油端连通的空间。利用桥架本身壳体构造形成油底盒,在保证桥架正常承载功能的同时利用桥架本身尺寸形成储油腔,结构紧凑,节省空间,可以避免在轮边机构的电机底部设置油底盒而对离地间隙的影响,有利于实现车辆低地板化。
