The invention discloses a steering axle and a vehicle thereof. The steering axle comprises a steering axle frame; the steering wheels are symmetrically arranged on the two sides of the steering bridge frame and rotate synchronously; the electric cylinder is arranged on the steering bridge frame and is used for driving the steering wheel on one side to rotate and linking the steering wheel on the other side to synchronously rotate; wherein the steering wheels on the two sides are arranged on wheel frames, the wheel frames are rotationally arranged at the two ends of the steering bridge frame through slewing bearings, and rotating spindles penetrating through the slewing bearings and the steering bridge frame are arranged on the wheel frames. The electric cylinder is used as a unique power source for steering, other power systems are not needed to participate or share, and waste of excess energy is effectively avoided; the single-action connecting rod type electric cylinder is adopted as power input, power input is stable, control precision is high, mechanical transmission mechanisms such as the gear and the lead screw are adopted, transmission precision is high, an operator can accurately control the starting and stopping position of the steering wheel, and high steering precision is achieved.
本发明公开了一种转向桥及其车辆,包括转向桥架;转向轮,其对称设置在转向桥架两侧,且具有同步转动;电缸,其设置在转向桥架上,用于驱动一侧的转向轮转动,并联动另一侧的转向轮同步转动;其中:两侧所述转向轮设置在轮架上,所述轮架通过回转支承转动设置在转向桥架两端,所述轮架上设置有贯穿回转支承和转向桥架的旋转主轴。本发明通过电缸作为转向独有动力源,不需其他动力系统参与或共用,有效避免多余能量浪费;本发明公开采用单作用连杆式电缸作为动力输入,动力输入稳定,控制精度高,且采用齿轮、丝杆等机械传动机构,传动精度较高,可使操作人员精准控制转向轮的启停位置,具备较高的转向精度。
