The electric power-assisted steering mechanism comprises a steering motor which is horizontally arranged, an output shaft of the steering motor is connected with a right-angle speed reducer, an output shaft of the right-angle speed reducer is connected with a small gear which is located below the right-angle speed reducer, and the axis of the small gear is vertically arranged. The small gear is meshed with an annular large gear with the axis vertically arranged. The upper surface of the annular large gear is connected with a top mounting plate connected with a frame of the explosion-proof storage battery tractor, the top mounting plate is of an 8-shaped structure and comprises a small hole used for allowing an output shaft of the right-angle speed reducer to penetrate through, and a large hole aligned with an annular hole of the annular large gear is formed in one side of the small hole; the lower surface of the annular large gear is connected with a steering combination 5. The structure is simple, the size is small, the turning diameter is reduced to 2 m from 7.5 m, and the operation flexibility is improved; meanwhile, the height of the whole vehicle is reduced to 0.6 m from the original 1.6 m, the height of the seat is reduced to 0.5 m from 1.2 m, and the weight of structural parts is reduced.
本发明提出了一种防爆蓄电池牵引车电助力转向机构,它包括水平布置的转向电机,所述转向电机输出轴连接有直角减速器,所述直角减速器输出轴连接有位于直角减速器下方、且轴线呈竖直布置的小齿轮,所述小齿轮啮合轴线呈竖直布置的环形大齿轮;所述环形大齿轮上表面连接有与防爆蓄电池牵引车的车架相连的顶部安装板,所述顶部安装板呈8字型结构,包括用于穿过直角减速器输出轴的小孔,所述小孔一侧设置有与环形大齿轮环形孔对准的大孔;所述环形大齿轮下表面连接有转向组合5。本发明结构简单体积小,转弯直径由原来的7.5m减小到2m,提升了操作灵活性;同时,整车高度由原来的1.6m降低到0.6m,座椅高度由1.2m降低到0.5m,降低了结构件重量。
