The embodiment of the invention relates to the technical field of vehicle parts, and discloses a box type structure electric steering axle for a four-wheel counterbalance forklift. The electric steering axle comprises a steering axle housing connected with a hub of a vehicle; the box cover is connected with the steering axle housing; the supporting shaft movably penetrates through the top of the box cover; the transition block is movably arranged on the outer wall of the supporting shaft in a sleeving manner; the steering rod movably penetrates through the middle of the box cover, is parallel to the supporting shaft and is fixedly connected with the transition block, and the two ends of the steering rod are connected with the hubs; and the output end of the driving assembly is connected with the side wall of the transition block, and the driving assembly is used for driving the transition block to move along the supporting shaft so as to synchronously drive the steering rod to control the wheel hub to steer. A combined structure of the transition block and the supporting shaft is adopted, the supporting shaft can provide additional support for the ball screw, and the tipping moment borne by the ball screw in the steering process is effectively shared.
本发明实施例涉及车辆零部件技术领域,公开了一种四轮平衡重叉车用箱式结构电转向桥。所述电转向桥包括:转向桥壳,与车辆的轮毂连接;箱盖,所述箱盖与所述转向桥壳的连接;支撑轴,活动贯穿于所述箱盖的顶部;过渡块,活动套设于支撑轴的外壁;转向杆,活动贯穿于所述箱盖中部,与所述支撑轴平行设置,且与所述过渡块固定连接,所述转向杆的两端与所述轮毂连接;驱动组件,所述驱动组件的输出端与所述过渡块的侧壁连接,所述驱动组件用于驱动所述过渡块沿着所述支撑轴移动,以同步带动所述转向杆控制所述轮毂转向。本发明采用了过渡块和支撑轴的组合结构,支撑轴的可以为滚珠丝杠提供额外的支撑,有效分担了其在转向过程中所承受的倾翻力矩。
