The invention provides a dual-motor multi-gear main reducer assembly and a vehicle, the dual-motor multi-gear main reducer assembly comprises dual motors, a front transmission, a rear three-stage reducer and a differential mechanism, an input driving gear is arranged on a first shaft of the front transmission, a first shaft section and a second shaft section are coaxially arranged on a second shaft of the front transmission, the two shaft sections are selectively jointed, and the differential mechanism is arranged on the first shaft of the front transmission. The first shaft section is provided with an input driven gear and a constant meshing driving gear, the second shaft section is provided with an output driving gear, the output driving gear is meshed with an output driven gear fixed to a differential mechanism, the second shaft section is sleeved with at least two gear shifting driven gears in an empty mode, and the third shaft section is provided with a constant meshing driven gear and at least two gear shifting driving gears. According to the invention, the power requirement of a large-tonnage vehicle can be met, the high-power and large-torque hybrid power system has the characteristics of high power, large torque and uninterrupted power, the power is converged on the differential mechanism assembly, and the advantages of mechanical differential speed and small axial width are achieved.

    本发明提供一种双电机多档位主减总成及车辆,其中,一种双电机多档位主减总成,包括双电机、前变速器、后三级减速器、差速器,前变速器第一轴上布置输入主动齿轮,第二轴同轴设置第一轴段和第二轴段,两轴段可选择性接合,第一轴段布置输入从动齿轮和常啮合主动齿轮,第二轴段布置输出主动齿轮,输出主动齿轮与固定于差速器的输出从动齿轮啮合,且第二轴段上至少空套两个换挡从动齿轮,第三轴上布置常啮合从动齿轮和至少两个换挡主动齿轮。本发明可满足大吨位车动力性需求,具有大功率、大扭矩和动力不中断的特点,且功率合流于差速器总成上,有机械差速和轴向宽度小的优势。
