The invention belongs to the technical field of agricultural mechanical parts, and particularly relates to a guide wheel assembly which comprises a hub integrally in a tubular shape and a rim integrally in a ring shape, and the rim is formed by combining two or more rim unit sections. The spokes are connected with the hub and the rim in a transition mode, and the outer end of the same spoke is connected with the two adjacent rim unit sections in an inserted mode and forms circumferential limiting fit with the rim unit sections. In addition, the spokes in transition connection with the hub and the rim are further used for achieving positioning installation of the rim unit sections, relative displacement of the spokes and the rim in the circumferential direction of the rim can be effectively limited, then damage to the wheel body caused by connection looseness of the spokes and the rim after long-term use is avoided, and the reliability of the wheel body structure of the guide wheel is guaranteed.
本发明属于农用机械零部件技术领域,特别涉及一种导向轮组件,包括整体呈管状的轮毂和整体呈环圈状的轮辋,轮辋由两个及以上的轮辋单元段组合形成;辐条过渡连接轮毂和轮辋,同一辐条的外端分别与两相邻布置的轮辋单元段插接连接并与之构成周向限位配合。本发明中过渡连接轮毂与轮辋的辐条还用于实现轮辋单元段的定位安装,能有效限制辐条与轮辋发生在轮辋周向方向上的相对位移,进而避免长期使用后二者连接松动导致的轮体受损,保证导向轮轮体结构的可靠性。
