The forklift steering drive axle device comprises an axle, a left hub, a right hub and a steering locking assembly, the steering locking assembly is connected with the axle, the left hub and the right hub, the left hub is arranged on one side of the axle, and the right hub is arranged on the other side of the axle. According to the invention, the angle sensor is axially arranged at the end part of the corner input shaft of the front axle steering booster of the high-speed forklift, so that the steering angle of the front axle can be detected; an angle sensor is axially arranged at the end of a steering rocker pin shaft of the rear axle to detect the steering angle of the rear axle. Through angle detection, comparison and control of the front axle angle sensor and the rear axle angle sensor, accurate follow-up steering of the rear axle along with the front axle is achieved; the steering locking oil cylinder is provided with an oil cylinder ventilation pipe, so that the steering locking oil cylinder can work under water in a submerged manner; the steering locking oil cylinder is provided with a position sensor, reliable locking of the rear axle is monitored and fed back, and the running reliability and stability of the whole vehicle are improved.

    本发明公开了一种叉车转向驱动桥装置及方法,所述装置,包括车桥、左轮毂、右轮毂和转向锁止组件,所述转向锁止组件分别与车桥、左轮毂、右轮毂连接,所述左轮毂设置在车桥一侧,所述右轮毂设置在车桥另一侧。本发明可通过在高速叉车的前桥转向助力器的转角输入轴端部轴向配置个角度传感器,检测前桥的转向角度;在后桥的转向摇杆销轴端部轴向配置角度传感器,检测后桥的转向角度。通过前桥和后桥角度传感器的角度检测、对比与控制,实现后桥随前桥的精确随动转向;通过转向锁止油缸设置了油缸通气管,使转向锁止油缸可淹没在水下工作;通过转向锁止油缸设置位置传感器,监测反馈了后桥的可靠锁止,提高了整车行驶的可靠性和稳定性。
