The invention relates to a steering wheel set mechanism of a transport vehicle, in particular to a steering wheel set mechanism which is used on a helicopter cargo transport vehicle and can steer and fixedly go straight, and belongs to the technical field of cargo transport vehicles. The wheel set mechanism comprises a supporting leg rod, a threaded connector, a bearing set, a limiting plug pin, a wheel set supporting base, a supporting shaft and a steering rod. The lower ends of two side plates of the wheel set supporting seat are fixedly connected with a supporting shaft of the tire assembly, and the upper ends are fixedly connected with the horizontal plate; the threaded connector is installed in an opening machined in the center of a horizontal plate of the wheel set supporting base through the bearing set and axially limited by the limiting component. The upper end of the threaded connector is in threaded fit with the lower end of the leg rod; the upper end of the supporting leg rod is connected with a flange hole of a transport vehicle frame flange seat; the wheel set mechanism can achieve large-angle steering through the bearing set so as to adjust the advancing direction of the cargo transportation trailer, and therefore alignment of the wheel direction of the helicopter cargo transportation trailer and a rail in a narrow area is achieved.
本发明涉及一种运输车转向轮组机构,具体地涉及一种用于直升机货物运输车上的、可转向和固定直行的转向轮组机构,属于货物运输车技术领域。所述轮组机构包括支腿杆、螺纹连接头、轴承组、限位插销、轮组支撑座、支撑轴和转向杆;轮组支撑座的两个侧板的下端与轮胎总成的支撑轴固连,上端与水平板固连;螺纹连接头通过轴承组安装在轮组支撑座水平板中心加工的开口内,并被限位部件轴向限位;螺纹连接头上端与支腿杆下端螺纹配合;支腿杆上端与运输车车架法兰座的法兰孔连接;所述轮组机构能够通过轴承组实现大角度的转向来调节货物运输拖车前进的方向,从而实现狭小区域内直升机货物运输拖车车轮方向与轨道的对正。
