The invention provides an electric drive axle, a vehicle and a control method of the electric drive axle, the electric drive axle comprises a shell assembly, a motor assembly, a transmission mechanism, a first half shaft, a second half shaft and a first supporting piece, and the shell assembly is provided with a hollow space; at least two first bearings are arranged between a motor output shaft of the motor assembly and the shell assembly; at least two second bearings are arranged between the transmission mechanism and the shell assembly; the first supporting piece is arranged in the shell assembly and divides the hollow space into a motor assembly installation space and a transmission mechanism installation space. And the at least one first bearing and the at least one second bearing are both mounted on the first supporting piece. According to the electric drive axle, due to the fact that the at least one first bearing and the at least one second bearing are both installed on the first supporting piece, the coaxiality of the output shaft of the motor and the transmission mechanism can be improved, abrasion between parts in the electric drive axle can be reduced, and the reliability and durability of the electric drive axle can be improved.

    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,包括外壳组件、电机组件、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;电机组件的电机输出轴与外壳组件之间设置有至少两个第一轴承;传动机构与外壳组件之间设置至少两个第二轴承;所述第一支撑件设置在所述外壳组件内,并分隔所述中空空间形成电机组件安装空间和传动机构安装空间;且至少一个第一轴承和至少一个第二轴承均安装在第一支撑件上。本申请中,由于至少一个第一轴承和至少一个第二轴承均安装在第一支撑件上,能够提高电机输出轴与传动机构的同轴度,有利于降低电驱动桥内零部件之间的磨损,也就有利于提高电驱动桥的可靠性、耐久性。
