The invention provides a dual-motor distributed electric drive axle and a vehicle, the electric drive axle comprises a first motor, a gear shaft system matched with the first motor, a second motor and a gear shaft system matched with the second motor, the first half shaft and the second half shaft are respectively arranged on the axle axis, and the first half shaft and the second half shaft are mutually independent. The three-stage speed reduction distributed transmission line is adopted, the number of transmission stages is small, efficiency is high, and a large gear speed ratio is easy to achieve. The space structure has symmetry, and the mass distribution is reasonable, so that the vibration resistance of the system is improved; meanwhile, the left half shaft and the right half shaft are independently driven by two motors and gear shaft systems of the motors, the distributed driving effect is achieved, and the driving system has better controllability and power redundancy; and meanwhile, the two-gear shifting function is achieved, and electric drive axle shifting power is not interrupted in the mode that left and right wheels alternately shift gears.

    本发明提出了一种双电机分布式电驱桥及车辆,电驱桥包括:第一电机以及与第一电机匹配的齿轮轴系,第二电机以及与第二电机匹配的齿轮轴系,其中,第一电机与第二电机均以车桥轴线为中心呈对称布置,还包括:分别布置在车桥轴线上的第一半轴和第二半轴,第一半轴和第二半轴相互独立。本发明采用三级减速的分布式传动路线,传动级数较少、效率高,容易实现较大的齿轮速比。空间结构具有对称性,质量分布合理,从而提升了系统的抗振性;同时,左右半轴由两路电机及其齿轮轴系独立驱动,实现了分布式驱动的效果,使得驱动系统更具有可控性和动力冗余性;同时具备两挡换挡功能,通过左右车轮交替换挡的方式实现电驱桥换挡动力不中断。
