The invention discloses a four-motor distributed control electric drive axle, and belongs to the technical field of electric drive axles, the four-motor distributed control electric drive axle comprises a matrix type four-motor drive unit and two double-path input two-stage speed reducers, the matrix type four-motor drive unit is four small-torque high-speed motors arranged in a matrix mode, and the two double-path input two-stage speed reducers are arranged in the matrix type. The matrix type four-motor driving unit comprises a first matrix type left motor, a second matrix type left motor, a first matrix type right motor and a second matrix type right motor, and output shafts of the first matrix type left motor and the second matrix type left motor are located on one side of the electric bridge. Output shafts of the first matrix type right motor and the second matrix type right motor are located on the other side of the bridge. The electric bridge is applied to a pure electric or hybrid power heavy commercial vehicle, solves the problem of power interruption during gear shifting of a conventional electric bridge, and is very compact, free of offset, light in weight, small in size and convenient for arrangement of the whole vehicle.

    本发明公开了一种四电机分布式控制电驱动桥,属于电驱动桥技术领域,一种四电机分布式控制电驱动桥,包括矩阵式四电机驱动单元和两个双路输入两级减速器,矩阵式四电机驱动单元为矩阵式布置的四个小扭矩高速电机,并基于电桥形成组合体,矩阵式四电机驱动单元包括矩阵式左电机一、矩阵式左电机二,矩阵式右电机一和矩阵式右电机二,矩阵式左电机一和矩阵式左电机二的输出轴位于电桥的一侧,矩阵式右电机一和矩阵式右电机二的输出轴位于电桥的另一侧。应用于纯电动或者混合动力的重型商用车上,它解决了常规电桥换挡时动力中断的问题,同时电桥非常紧凑,没有偏置,重量轻,体积小,方便整车布置。
