The invention belongs to the field of mining trucks, and particularly relates to an electric drive axle provided with double motors and used for a pure electric mining truck, which comprises a double-motor and two-stage double-intermediate-shaft transmission device and a differential mechanism assembly used for power superposition and differential. The two driving motors and the two transmission devices achieve power superposition in the differential mechanism shell and then transmit power to wheel edges through the differential mechanism assembly. Double motors, two-stage double-intermediate-shaft transmission and wheel edge transmission are adopted, the double motors are arranged in a front-and-back crossed mode, arrangement of large-size motors with high output performance can be met, two-stage double-intermediate-shaft transmission devices on the two sides are arranged in a crossed mode, and the output requirements for high torque and rotating speed of a whole vehicle can be met through two-stage speed ratio superposition; and meanwhile, the double intermediate shafts can meet the requirement for large-torque transmission of gear strength.

    本发明属于矿用卡车领域,尤其为一种用于纯电动矿卡车的配置双电机的电驱动桥,包括双电机加二级双中间轴传动装置及用于动力叠加及差速的差速器总成,两个驱动电机及两套传动装置在差速器壳体实现动力叠加后通过差速器总成将动力传递至轮边。采用双电机+二级双中间轴传动+轮边传动,双电机前后交叉布置,可满足较高输出性能大尺寸电机的布置,两侧二级双中间轴传动装置交叉布置,通过两级速比叠加可满足整车较高扭矩及转速的输出需求,同时双中间轴可实现大扭矩传递齿轮强度的需求。
