Abstract
A four-mode dual-motor coupled electric drive axle, including a primary drive motor, an auxiliary drive motor, a reducer, a torque vectoring (TV) coupler, a power coupling differential, a housing, and a power output mechanism. The TV coupler is switchable among disconnected mode, TV mode, and reducer mode by controlling a first clutch and a second clutch. The power coupling differential is switchable between torque coupling mode and speed coupling mode by controlling a third clutch. The electric drive axle is switchable among single-motor drive mode, TV drive mode, dual-motor torque coupling drive mode, and dual-motor speed coupling drive mode by controlling the TV coupler and the power coupling differential.
