The invention provides a rear wheel steering gear and a vehicle. The rear wheel steering gear comprises a steering motor, a transmission mechanism and a lead screw, the steering motor is used for driving the lead screw to drive rear wheels of the vehicle to steer after changing the rotating speed through the transmission mechanism, and the distance between the central axis of a motor shaft of the steering motor and the central axis of a screw rod of the lead screw is smaller than the shell radius of the steering motor in the radial direction of the screw rod of the lead screw. According to the rear wheel steering gear, by limiting the radial distance between the steering motor and the lead screw, the size of the rear wheel steering gear is reduced so as to increase the internal space of a vehicle.

    本申请提供一种后轮转向器和一种车辆。后轮转向器包括转向电机、传动机构和丝杠,转向电机用于通过传动机构变换转速后驱动丝杠带动车辆的后轮转向,沿丝杠的螺杆径向转向电机的电机轴中心轴线与丝杠的螺杆中心轴线之间的间距小于转向电机的壳体半径。本申请提供的后轮转向器通过限制转向电机和丝杠的径向间距,缩小后轮转向器的体积以增大车辆内部空间。
