The invention provides an active steering mechanism of a platform trailer. The active steering mechanism comprises a bearing turntable assembly, a first rotating arm assembly, a rotating rod assembly, a second rotating arm assembly, a turntable, a bogie assembly and wheels. Practicality and reliability of the steering mechanism are fully considered, all components are optimized, and the steering direction, the steering angle and the steering force of the platform trailer can be accurately controlled. According to the active steering mechanism, two wheel trains are formed by two rotating discs with small tonnage, the two wheel trains are connected with a middle steering traction frame through a plane connecting rod assembly, when the middle traction frame steers, the steering force, the steering angle and the steering direction of the traction frame are transmitted to the wheel trains at the two ends through a plane connecting rod mechanism, and therefore steering of the platform trailer is achieved. The steering mechanism is an active steering mechanism capable of controlling the steering angle of the wheels, and has the characteristics of flexibility in steering, high load capacity, uniformity and stability in stress of the platform trailer, simple structure, accuracy in steering, small structural stress, high reliability and the like.
本发明提出一种平板拖车主动转向机构,包括轴承转盘组件、第一转臂组件、转杆组件、第二转臂组件、转盘、转向架组件和车轮。本机构充分考虑转向机构的实用性及可靠性,对各组成部分进行优化,能够精准控制平板拖车的转向方向、转向角度及转向力度。主动转向机构由两个吨位较小的转盘组成两个轮系,两个轮系通过平面连杆组件与中间转向牵引架连接,当中间牵引架转向时,牵引架的转向力与转向角度、方向通过平面连杆机构传递到两端轮系上,从而实现平板拖车转向。这种转向机构是可控制车轮转向角度的主动转向机构,具有转向灵活、载重量高、平板拖车受力均匀与稳定、结构简单、转向精确,结构受力小,可靠性高等特点。
