Rear wheel steering gear, power assembly and vehicle

Abstract

The invention provides a rear wheel steering gear, a power assembly and a vehicle, the rear wheel steering gear comprises a steering motor, a lock-up clutch, a lead screw transverse pull rod and a steering motor controller, and the steering motor controller is used for driving the steering motor to rotate and driving the lead screw transverse pull rod through the lock-up clutch to achieve steering of rear wheels of the vehicle; the steering motor controller is further used for driving the steering motor to rotate and output torque to limit the rotation angle of the lock-up clutch to be smaller than the preset angle after steering of the rear wheels is completed. According to the rear wheel steering gear, the locking torque of the locking clutch is compensated through the steering motor, it is guaranteed that a vehicle runs reliably, and power consumption of the steering motor is reduced.
