The embodiment of the invention discloses a main-auxiliary motor double-speed-ratio electric automobile drive axle which comprises a rear axle shell and a differential mechanism assembly and further comprises a main drive assembly and an auxiliary drive assembly which are installed on the two sides of the rear axle shell, and the main drive assembly comprises a first end cover, a main motor and a first transmission set. The auxiliary driving assembly comprises a second end cover, an auxiliary motor and a second transmission set, the first transmission set is arranged in the first end cover and connected with the main motor, the second transmission set is arranged in the second end cover and connected with the auxiliary motor, a gear ring is arranged between the first transmission set and the second transmission set in a transmission connection mode, and the differential mechanism assembly is installed in the gear ring. And the second transmission group is connected with an overrun clutch. By the adoption of the technical scheme of the double-speed ratio of the main motor and the auxiliary motor, the ultra-large torque needed when a vehicle climbs in a full-load mode can be met, the requirement for the maximum vehicle speed can be met, the structure is simple, the transmission link is simplified to the maximum, efficiency can be greatly improved, and energy consumption can be greatly reduced.

    本发明实施例公开了一种主副电机双速比电动汽车驱动桥,包括后车桥壳体和差速器总成,还包括于后车桥壳体两侧安装的主驱动总成和副驱动总成,主驱动总成包括第一端盖、主电机以及第一传动组,副驱动总成包括第二端盖、副电机以及第二传动组,第一传动组内置在第一端盖内,并与主电机连接,第二传动组内置在第二端盖内,并与副电机连接,在第一传动组和第二传动组之间,传动连接齿圈,差速器总成安装在齿圈内,并在第二传动组上连接有超越离合器。本发明采用主副电机双速比技术方案,可满足车辆在满载爬坡时所需要的超大扭矩,还可兼顾最高车速要求,结构简洁,传动环节精简到极致,可大幅度提高效率,降低能耗。
