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.
本申请提供一种后轮转向器、一种动力总成和一种车辆,后轮转向器包括转向电机、锁止离合器、丝杠横拉杆和转向电机控制器,转向电机控制器用于驱动转向电机转动并通过锁止离合器带动丝杠横拉杆实现车辆的后轮转向,转向电机控制器还用于在后轮转向完成后驱动转向电机旋转输出转矩以限制锁止离合器的转动角度小于预设角度。本申请提供的后轮转向器通过转向电机补偿锁止离合器的锁止力矩,保证车辆可靠行驶并减小转向电机的功耗。
