摘要： A dual-motor drive assembly and a vehicle are disclosed. The dual-motor drive assembly comprises a first motor and a second motor arranged coaxially, a first gear transmission, a second gear transmission, and one or more idle gear pairs (42, 52). The first gear transmission is driven by the first motor, and the second gear transmission is driven by the second motor. The idle gear pairs (42, 52) are respectively arranged in the first gear transmission and the second gear transmission and are configured to increase a distance between an output shaft of the first motor (15) and an end shaft of the first gear transmission. By adding the idle gears, the center distance between the input shaft and the output shaft in the assembly can be adjusted more flexibly by adjusting the size of the idle gears to realize a larger center distance and make full use of the structural space brought by the larger center distance to install other components; moreover, it can be adjusted according to the space layout requirements and performance requirements of different users.
