The invention discloses a central distribution type double-motor electric drive bridge structure. The central distribution type double-motor electric drive axle structure comprises a first motor, a second motor, a first speed reducer, a second speed reducer, a left output half shaft, a right output half shaft, a left drive wheel and a right drive wheel. The left output half shaft and the right output half shaft are located on the same axis. The first motor and the second motor are distributed in a central symmetry manner relative to the axis; the first speed reducer and the second speed reducer are distributed on the left side and the right side of the first motor and the second motor respectively. The first motor and the second motor are distributed in a central symmetry mode, and the first speed reducer and the second speed reducer are distributed in a central symmetry mode, so that structural integration, light weight and uniform overall load distribution are realized, the influence on the overall structural strength of the drive axle is small, and the problem of gravity center shift of a dual-motor offset power assembly is avoided; the reliability of the whole system is improved, the structure is compact, and the occupied space is reduced.

    本申请公开了一种中央分布式双电机电驱桥结构。该中央分布式双电机电驱桥结构包括第一电机、第二电机、第一减速器、第二减速器、左输出半轴、右输出半轴、左驱动轮和右驱动轮;所述左输出半轴和所述右输出半轴位于同一轴线上;所述第一电机和所述第二电机相对于该轴线呈中心对称分布;所述第一减速器和第所述二减速器分布在所述第一电机和所述第二电机的左右两侧。本申请采用第一电机和第二电机呈中心对称分布方式,且第一减速器和第二减速器呈中心对称分布方式,实现结构集成化、轻量化,总体负荷均布,对驱动桥整体结构强度影响较少,避免了双电机偏置式动力总成存在的重心偏移问题,提高整套系统的可靠性,并且使结构紧凑,减少了占用空间。
