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.
