The invention discloses a lubricating structure of an electric drive axle. The lubricating structure comprises a gearbox shell and a gearbox end cover. The gearbox shell is fixedly connected with the gearbox end cover, a first bearing hole and a fourth bearing hole are formed in the gearbox shell, height difference exists between the end face of the first bearing hole and the end face of the fourth bearing hole, and the outer side of the first bearing hole is a vertical plane. A first oil duct, a second oil duct and a third oil duct are respectively arranged on the gearbox shell, and the first oil duct is communicated with the first bearing hole; the second oil duct and the third oil duct are oppositely arranged on the two sides of the fourth bearing hole and communicate with the fourth bearing hole, and the second oil duct communicates with the vertical plane. Oil ducts are arranged on the same gearbox shell when the gearbox is mounted in a front-mounted mode and a rear-mounted mode, so that the problem that a lubricating structure cannot be used universally when the gearbox is arranged at different positions of a whole vehicle is solved.

    本发明公开了一种电驱桥的润滑结构,包括变速箱壳体、变速箱端盖;所述变速箱壳体与变速箱端盖固定连接,所述变速箱壳体内设置有第一轴承孔和第四轴承孔,所述第一轴承孔与第四轴承孔的端面具有高度差,且所述第一轴承孔外侧为竖直平面,所述变速箱壳体上分别设置有第一油道、第二油道和第三油道,所述第一油道与第一轴承孔连通;所述第二油道、第三油道相对设置在所述第四轴承孔两侧并与所述第四轴承孔连通,所述第二油道与竖直平面连通。通过将变速箱前置和后置安装时的油道设置在一个变速箱壳体上,解决了变速箱在不同整车位置上布置时润滑结构无法通用的问题。
