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.
