The invention provides a drive axle, a vehicle and a control method of the drive axle, and relates to the technical field of vehicles. A containing space is defined by the shell, the partition piece protrudes into the containing space from the bottom of the shell, the partition piece divides the containing space into a first containing cavity and a second containing cavity, the driven gear is arranged in the first containing cavity, a communicating hole communicating the first containing cavity with the second containing cavity is formed in the partition piece, and the blocking piece is arranged on the communicating hole. The blocking piece can open or close the communicating hole. When the vehicle is in a harsh working condition, the plugging piece opens the communicating hole, and the lubricating oil in the second containing cavity can enter the first containing cavity to supplement the lubricating oil in the first containing cavity, so that the oil stirring amount of the driven gear is ensured. When the vehicle is in a general working condition, the blocking piece blocks the communicating hole, and lubricating oil in the second containing cavity cannot enter the first containing cavity. Therefore, the oil stirring quantity of the driven gear when the vehicle is in a general working condition is reduced, the oil stirring loss is reduced, and the transmission efficiency of the drive axle is improved.

    本发明提供一种驱动桥、车辆及驱动桥的控制方法,涉及车辆技术领域。外壳围设出容纳空间,分隔件自外壳的底部向容纳空间内凸出,分隔件将容纳空间划分为第一容纳腔和第二容纳腔,从动齿轮设置在第一容纳腔内,分隔件上开设有连通第一容纳腔和第二容纳腔的连通孔,封堵件设置在连通孔上,封堵件能够开启或者封闭连通孔。在车辆处于严苛工况时,封堵件开启连通孔,第二容纳腔内的润滑油能够进入第一容纳腔内补充第一容纳腔内的润滑油,以确保从动齿轮的搅油量。在车辆处于一般工况时,封堵件封堵连通孔,第二容纳腔内的润滑油不会进入第一容纳腔。如此,降低了车辆处于一般工况时的从动齿轮的搅油量,降低了搅油损失,提升了驱动桥的传动效率。
