The invention discloses a steering drive axle for a forklift, belongs to the technical field of forklifts, and solves the problems that a drive axle of the forklift is insufficient in driving force, and the forklift is easy to fall into muddy ground and cannot get out of the muddy ground. The axle shaft assembly achieves steering movement and rotating movement of the steering hub assembly through a universal joint structure, a steering knuckle assembly is further arranged between the end of the axle body assembly and the hub assembly, and the steering knuckle assembly is rotationally connected to the end of the axle body assembly and connected with a steering oil cylinder assembly through a rocker arm structure. The steering range of the steering knuckle assembly driven by the oil cylinder assembly is as follows: the pulling deflection range is 0-45 degrees; the outer pushing deflection range is 0-62 degrees, the maximum rotating angle range is 62 degrees, the main speed reducer can achieve skid resistance through the differential lock, and when a tire on one side slips or sinks into the muddy ground, the differential lock automatically locks a half shaft and automatically outputs torque, so that the forklift can normally run and break away from the dilemma.

    本发明公开了一种叉车用转向驱动桥,属于叉车技术领域,解决了叉车的驱动桥驱动力不足,容易陷入泥泞地出不来的问题,其技术方案要点是轮毂总成和主减速器总成之间设置有半轴总成,半轴总成通过万向节结构实现转向轮毂总成的转向活动和旋转活动,所述桥体总成的端部和轮毂总成之间还设置有转向节组件,所述转向节组件转动连接在桥体总成的端部并通过摇臂结构连接转向油缸总成,所述油缸总成驱动转向节组件转向范围如下:拉动偏转范围0‑45°;外推偏转范围为0‑62°,达到了具有最大转角62度的范围,主减速器能够利用差速锁来实现防滑,当一边的轮胎打滑或陷入泥泞地时,差速锁自动锁紧半轴,自动输出扭矩,使得叉车能够正常行驶并脱离困境。
