Abstract
A multi-mode torque vectoring electric drive axle, including a main motor, an auxiliary motor, a differential, a first half shaft, a second half shaft, a primary reducer, a secondary reducer, a planetary gear set, a dual-gear mechanism and a three-phase actuator. The main motor and the auxiliary motor are respectively connected to input ends of the primary reducer and the secondary reducer. Output ends of the primary reducer and the secondary reducer are respectively connected to a differential housing and an input end of the planetary gear set. Two output ends of the planetary gear set are respectively connected to the three-phase actuator and the dual-gear mechanism. An output end of the dual-gear mechanism is connected to the differential housing. The three-phase actuator is a synchronous shifting mechanism for enabling locking, decoupling of the planetary gear set, and connection to the first half shaft.
