摘要： 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.

摘要： A dual-mode active rear-wheel steering device, including: a steering angle control motor, a speed-reduction mechanism, a differential mechanism assembly, two steering motion conversion mechanisms, a first electromagnetic clutch and a second electromagnetic clutch. An output end of the steering angle control motor is connected to the speed-reduction mechanism. The differential mechanism assembly is a bevel gear differential, in which center holes at outer ends a two half shafts are respectively provided with a raceway to form an inner cyclical ball-lead screw-nut pair with a first lead screw and a second lead screw of the steering motion conversion mechanisms. The first lead screw and the second lead screw are the same in parameters but with opposite rotation direction. The first electromagnetic clutch controls connection between a differential housing and a frame. The second electromagnetic clutch controls connection between the differential housing and the second half shaft.

摘要： 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.

摘要： A dual-mode electric drive axle with torque parallel coupling and torque vectoring, including: a main motor, an auxiliary motor, a spur gear differential, a first half shaft, a second half shaft, a primary reducer, a secondary reducer, a dual-planetary gear set mechanism, a first clutch, a second clutch and a primary housing. 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 housing of the spur gear differential and a gear ring of the dual-planetary gear set mechanism. A planet carrier of the dual-planetary gear set mechanism is connected to a sun gear through a first clutch, and a gear ring through a second clutch. A characteristic parameter of the dual-planetary gear set mechanism is 2.
