Abstract: A drive axle assembly (10) of a vehicle is provided. The drive axle assembly includes a motor (1); a first shaft (13) and a second shaft (14). A right planet row mechanism is disposed on the first shaft (13), and a left planet row mechanism is disposed on the second shaft (14). A right sun gear (41) of the right planet row mechanism is connected with the first shaft (13). A left sun gear (61) of the left planet row mechanism is connected with the second shaft (14). The right sun gear (41) has a right central oil passage (411) and a right radial oil passage (412). The right central oil passage (411) is in communication with the first shaft. The left sun gear (61) has a left central oil passage (611) and a left radial oil passage (612). The left central oil passage (611) is in communication with the second shaft (14). The first shaft (13) is in communication with the second shaft (14) to supply oil to the second shaft (14).
