The invention relates to a stroke limiting structure, a rear wheel steering gear and a vehicle, the stroke limiting structure comprises a lead screw, a nut, a movable limiting stopper and a rotary limiting stopper, and the nut can rotate around the axial direction of the nut; the screw rod is inserted into the nut in a penetrating manner, is in threaded connection with the nut and can move in the axial direction of the screw rod; the movable limiter is in transmission connection with the screw rod and is used for limiting the axial movement of the screw rod; and the rotary limiter is in transmission connection with the screw rod and is used for limiting the rotation of the screw rod. The limiting device has the beneficial effects that the structure is simple, the assemblability is good, the design is reasonable, circumferential limiting is adopted, the possibility of limit jamming can be prevented, it is ensured that the steering function is not invalid, and the steering limiting stroke is adjusted by adjusting the axial position of the limiting block.

    本发明涉及一种行程限位结构、后轮转向器及车辆,该行程限位结构包括丝杆、螺母、移动限位器和旋转限位器,所述螺母可绕自身轴向转动;所述丝杆穿插在所述螺母内,其与所述螺母螺纹连接,且其可沿自身轴向移动;所述移动限位器与所述丝杆传动连接,用于对所述丝杆的轴向移动进行限位;所述旋转限位器与所述丝杆传动连接,用于对所述丝杆的旋转进行限位。本发明的有益效果是结构简单,可装配性好,设计合理,采用周向限位,可防止出现极限卡死的可能,确保转向功能不失效,并通过限位块轴向位置的调整,调整转向限位行程。
