The invention discloses an independent electronic steering axle and a four-fulcrum counterbalance forklift truck. The steering axle comprises: a swing axle rotationally connected with a truck body; wheel carriers which are arranged at the two ends of the swing axle respectively, wherein the upper portions of the wheel carriers are rotationally connected with one end of the swing axle through rotary supports, and the lower portions are provided with steering wheels; steering motors which are arranged at the two ends of the swing axle respectively; and feedback assemblies which are arranged at the two ends of the swing axle respectively. The independent electronic steering axle is arranged to replace a traditional hydraulic steering axle to be applied to the four-fulcrum counterbalance forklift truck, the steering function of the forklift truck is achieved, the accurate steering control progress can be provided, the steering response speed is greatly improved, and the energy consumption and noise of the forklift truck are reduced; and meanwhile, the two sets of steering wheels can rotate by 360 degrees, mutual interference of mechanisms is avoided, the forklift has the minimum turning radius mode, the rotation radius of the forklift is greatly reduced, and the flexibility of the forklift is improved.

    本发明公开了一种独立电子转向桥及四支点平衡重式叉车,包括摆动桥,其与车体转动连接;轮架,其分别设置在摆动桥两端,所述轮架上部通过回转支撑与摆动桥一端可转动连接,其下部安装有转向轮;转向电机,其分别设置在摆动桥两端;以及反馈总成,其分别设置在摆动桥两端。本发明通过设置独立电子转向桥取代传统的液压转向桥应用在四支点平衡重式叉车上,实现叉车的转向功能,能够提供精确的转向控制进度,大幅改善转向响应速度,降低叉车能耗,降低噪音;同时,两组转向轮均可360°回转,无机构相互干扰,使得叉车具有最小转弯半径模式,大幅降低了叉车的回转半径,提高了叉车的灵活性。
