Abstract: A drive axle assembly includes a motor; a first shaft and a second shaft. A right planet row mechanism is disposed on the first shaft, and a left planet row mechanism is disposed on the second shaft. A right sun gear of the right planet row mechanism is connected with the first shaft. A left sun gear of the left planet row mechanism is connected with the second shaft. The right sun gear has a right central oil passage and a right radial oil passage. The right central oil passage is in communication with the first shaft. The left sun gear has a left central oil passage and a left radial oil passage. The left central oil passage is in communication with the second shaft. The first shaft is in communication with the second shaft to supply oil to the second shaft.
