The invention discloses a rear wheel steering gear assembly and a vehicle, and relates to the technical field of rear wheel steering. The rear wheel steering gear assembly comprises a shell, a transmission structure and a driving structure, a steering shaft is arranged in the shell, the transmission structure comprises a lead screw and a nut, the lead screw is connected with the nut, the driving structure comprises a motor and a sensor, the motor is in driving connection with the nut, the sensor is installed on the shell, and the motor is connected with the nut. The sensor is electrically connected with the motor, the sensor can obtain the displacement change of the lead screw, and the motor is provided with an electric control self-locking module. According to the rear wheel steering gear assembly, due to the fact that a tedious mechanical self-locking structure is omitted, system self-locking is achieved in a motor control mode; due to the fact that a mechanical self-locking structure is omitted, according to the traditional efficiency of the rear wheel steering gear assembly, the transmission efficiency can reach 60%-80% by optimizing parameters such as the outer diameter or the lead of the lead rod, the transmission efficiency is greatly improved, and the overall energy consumption is reduced.

    本发明公开了后轮转向器总成及车辆,涉及后轮转向技术领域;后轮转向器总成包括:外壳、传动结构、驱动结构,其中所述的外壳中设有转向轴,所述传动结构包括丝杆、螺母,所述丝杆与所述螺母连接,所述驱动结构包括电机、传感器,所述电机与所述螺母驱动连接,所述传感器安装在壳体上,所述传感器与所述电机电连接,所述传感器能获知所述丝杆的位移变化,所述电机具有电控自锁模块。本后轮转向器总成由于取消的繁琐的机械自锁结构,通过采用电机控制方式实现系统自锁;由于取消了机械自锁结构,因此本后轮转向器总成的传统效率可以通过优化丝杆的外径或者导程等参数,实现传动效率能达到60%~80%,大大提高了传动效率,降低总体能耗。
