The invention relates to the technical field of automobile parts, in particular to a follow-up steering axle. According to the steering axle, a wheel end assembly is connected with an axle tube assembly through a steering main pin, the steering main pin and the center of an axle tube have certain offset, when a vehicle turns, the wheel end assembly is pushed to generate rotating torque, steering force of the wheel end assembly is achieved, the wheel end assembly can rotate around the steering main pin, and the steering function of the wheel end assembly is achieved; the return locking device is fixed to the axle tube assembly, a return air bag and a locking air cylinder are installed on the return locking device, the return air bag is inflated to drive the transverse pull rod to pull the wheel end assembly to turn and return, after the wheel end assembly returns to the right position, the locking air cylinder can be controlled to fix the transverse pull rod, and then steering locking of the wheel end assembly is achieved. The steering axle has the automatic follow-up steering function, the turning radius can be reduced, the trafficability of a vehicle is improved, and the problem that an existing steering axle cannot conduct self-adaptive steering running according to the turning requirement of the vehicle is solved.

    本申请涉及汽车部件技术领域,尤其是涉及一种随动转向桥。该转向桥中轮端总成与轴管总成通过转向主销连接,该转向主销与轴管中心具有一定的偏移量,当车辆转弯时会推动轮端总成产生转动扭矩,实现轮端总成的转向力,轮端总成可绕转向主销旋转,实现轮端总成的转向功能,回正锁止装置固定于轴管总成上,回正锁止装置上安装有回正气囊及锁止气缸,通过回正气囊充气可带动横拉杆拉动轮端总成转向回正,当轮端总成回正到位后可控制锁止气缸将横拉杆固定,进而实现轮端总成的转向锁止。该转向桥具有自动随动转向功能,可以减小转弯半径,提高车辆的通过性,解决了现有的转向桥无法根据车辆的转弯需求进行自适应转向行驶的问题。
