The invention provides a centralized lubrication electric drive axle which comprises an axle housing, and driving parts are fixedly arranged at the two ends of the axle housing. The cooling and lubricating system is used for cooling and circulating lubricating oil; an oil bottom box is fixedly arranged on the axle housing, an oil suction port is formed in the bottom of the oil bottom box and communicated with an inlet of a cooling and lubricating system through a pipeline, and an outlet of the cooling and lubricating system is communicated with oil inlets of driving components on the left side and the right side through oil inlet pipes respectively. An oil return pipe for communicating the oil outlet of the driving part on each side with the oil bottom box is arranged in the oil bottom box; when the axle housing inclines, the oil return ports of the two oil return pipes are located above the oil surface of the oil bottom box all the time, and the oil suction port is located below the oil surface all the time.

    本发明提供一种集中润滑电驱桥,包括桥壳、所述桥壳的两端都固定设置驱动部件;还包括对润滑油进行冷却以及循环的冷却润滑系统;所述桥壳上固定设置一个油底盒,所述油底盒底部设置吸油口,所述吸油口通过管道与冷却润滑系统的进口连通,所述冷却润滑系统的出口通过进油管分别连通左、右两侧的驱动部件的进油口;所述油底盒内设置将每侧驱动部件出油口分别与油底盒连通的回油管;桥壳倾斜时,两个所述回油管的回油口始终位于所述油底盒的油面的上方,所述吸油口始终位于油面的下方。
