The invention provides a dual-motor multi-gear main reducer assembly and a vehicle, the dual-motor multi-gear main reducer assembly comprises a first motor, a front transmission, a second motor, a rear transmission and a differential assembly, the first motor, the front transmission, the second motor and the rear transmission are symmetrically arranged on the two sides of the differential assembly respectively, and the first motor and the front transmission are symmetrically arranged on the two sides of the differential assembly respectively. And the power converges to the same cylindrical wheel fixed on the differential mechanism assembly. Meanwhile, the first motor, the front transmission gear shaft, the differential mechanism assembly, the second motor and the rear transmission gear shaft are arranged in parallel, and the gear shifting gear is arranged on the second shaft. Double motors are adopted for driving, the front speed changer and the rear speed changer transmit power for the three-stage two-gear double speed reducer, the problems that high-power motor resources are scarce, the motor transmission efficiency is low under the low-load working condition, gear shifting power is interrupted and the like can be solved, and the power requirement of a large-tonnage off-highway vehicle is met.

    本发明提供一种双电机多挡位主减总成及车辆,其中,双电机多挡位主减总成,包括第一电机、前变速器、第二电机、后变速器、差速器总成,其中第一电机、前变速器和第二电机、后变速器分别位于差速器总成的两侧对称布置,功率合流至同一固定于差速器总成的圆柱轮上。同时,第一电机、前变速器齿轮轴、差速器总成、第二电机、后变速器齿轮轴平行布置,换挡齿轮布置在第二轴上。本发明采用双电机驱动、前、后变速器为三级两挡双减速器传递动力,可解决大功率电机资源稀缺、低负荷工况下电机传动效率低、换挡动力中断等问题,满足大吨位非公路车动力性需求。
