The invention provides a reconfigurable wheel-track composite propelling mechanism. The trafficability of the propelling mechanism in a track mode is improved to a great extent. Comprising a frame assembly, hubs, a chain wheel set, an elastic crawler belt, a main shaft clutch and a chassis clutch. The elastic crawler belt is an annular belt with teeth on the inner surface; the chain wheel group comprises a plurality of chain wheels which are uniformly distributed on the inner circumferential surface of the elastic crawler belt at intervals along the circumferential direction and are provided with outer teeth; the chain wheel is meshed with the elastic track through outer teeth; one side of the frame assembly is hinged to the hub, the other side of the frame assembly is hinged to the chain wheel set, the elastic crawler belt is driven to deform through deformation of the frame assembly, and therefore switching between a wheel type mode and a crawler belt mode is achieved. In the crawler belt mode, the elastic crawler belt forms a polygonal structure which is symmetrical about the axis of the vehicle main shaft, and the front supporting section and the rear supporting section of the propelling mechanism are crawler belt sections formed by sequentially and smoothly connecting straight line sections and arc sections. The vehicle spindle is connected with the hub through the spindle clutch, and the chassis clutch is installed between the hub and the vehicle body.

    本发明提供一种可重构轮履复合推进机构,较大程度上提高了推进机构履带模式下的通过性。包括:框架组件、轮毂、链轮组、弹性履带、主轴离合器和底盘离合器;弹性履带为内表面设置有齿的环形带;链轮组为在弹性履带内圆周面沿周向均匀间隔分布的若干具有外齿的链轮;链轮通过外齿与弹性履带啮合;框架组件的一侧与轮毂铰接,另一侧与链轮组铰接,通过框架组件的变形,带动弹性履带变形,由此在轮式模式和履带模式之间切换;履带模式下,履带模式下,弹性履带形成关于车辆主轴轴对称的多边形结构,且推进机构的前支段和后支段为由直线段和圆弧段依次光滑连接形成的履带段;车辆主轴通过主轴离合器与轮毂相连,底盘离合器安装在轮毂与车体之间。
