The invention provides an electric drive axle, a vehicle and a control method of the electric drive axle. The electric drive axle comprises a motor, a transmission mechanism, a first half shaft, a second half shaft and a first supporting piece, and a shell assembly is provided with a hollow space; the motor comprises a motor output shaft, and the motor output shaft is provided with a first axial through hole; the transmission assembly comprises a first shell and a transmission mechanism, the first shell is provided with a first inner space, the transmission mechanism is arranged in the first inner space, the first half shaft penetrates through the first axial through hole, and a gap is formed between the first half shaft and the hole wall of the first axial through hole; the first oil seal is arranged in the gap in a sealed mode, and the gap and the first inner space are separated by the first oil seal. In the application, the first oil seal can prevent the oil liquid used for lubricating the transmission mechanism in the first internal space from entering the gap, so that the oil stirring phenomenon can be prevented, the heating of the first half shaft and the motor output shaft beside the gap can be reduced, and the noise can be reduced.

    本申请提供一种电驱动桥、车辆及电驱动桥的控制方法,本申请的电驱动桥,包括电机、传动机构、第一半轴、第二半轴和第一支撑件外壳组件具有中空空间;电机包括电机输出轴,电机输出轴设置有第一轴向贯通孔;传动组件,包括第一外壳和传动机构,第一外壳具有第一内部空间,传动机构设置在所述第一内部空间中,第一半轴贯穿第一轴向贯通孔,并与第一轴向贯通孔的孔壁之间形成间隙;第一油封,密封设置在所述间隙内,所述第一油封隔开所述间隙和所述第一内部空间。本申请中,该第一油封能够避免第一内部空间内用于润滑传动机构的油液进入该间隙内,有利于防止搅油现象发生,也就有利于减少该间隙旁的第一半轴和电机输出轴的发热,降低噪音。
