The invention discloses a hydraulic steering axle for a three-fulcrum forklift. The hydraulic steering axle comprises a steering assembly, the steering assembly comprises a main shaft, the lower end of the main shaft is connected with a steering shaft, and the upper portion of the main shaft is connected with a steering power part used for driving the steering main shaft to rotate; the steering power part comprises a hydraulic motor assembly and a transmission case which are in power connection with the main shaft, the hydraulic motor assembly comprises a hydraulic motor, an output shaft of the hydraulic motor is sleeved with a first transmission gear, a reduction gear set is arranged in the transmission case, the first transmission gear is in power connection with the input gear of the reduction gear shaft, and an output gear of the reduction gear shaft is in power connection with the main shaft. The hydraulic motor is arranged and drives the steering main shaft to rotate so that a transverse oil cylinder and a gear rack on an original steering axle are omitted, and the size of steering equipment is greatly reduced, and thus the steering axle is simpler and more compact.

    本发明公开了一种三支点叉车用液压转向桥,包括转向总成,所述转向总成包括主轴,所述主轴下端连接有转向轴,所述主轴上方连接有用于带动所述转向主轴转动的转向动力部;所述转向动力部包括与所述主轴动力连接的液压马达总成、传动箱,所述液压马达总成包括液压马达,所述液压马达的输出轴上套接有第一传动齿轮,所述传动箱内设有减速齿轮组,所述第一传动齿轮与所述减速齿轮轴的输入齿轮动力连接,所述减速齿轮轴的输出齿轮与所述主轴动力连接,本申请通过设置液压马达,通过液压马达带动转向主轴进行转动,因而取消了原有转向桥上的横置油缸以及齿轮齿条,极大了降低了转向设备的尺寸,使得转向桥更加简单紧凑。
