According to the liftable belt-driven crawler walking mechanism, under the soft road condition on land, multistage telescopic arms and crawler walking units extend outwards in sequence till a crawler is in contact with the ground through the outward extension of the multistage telescopic oil cylinders, and under the use working condition, the crawler walking units are used for sharing the load of the whole vehicle; the ground contact area of wheels and a crawler belt of the whole vehicle is increased, the ground contact specific pressure of the whole vehicle is reduced, and the trafficability of the whole vehicle under soft road conditions can be improved; under the water working condition, in order to reduce water resistance brought by the lifting belt-driven crawler walking mechanism, the multi-stage telescopic arm and the crawler walking unit can be completely contracted into the vehicle body by controlling the contraction of the multi-stage telescopic oil cylinder, so water resistance of the mechanism can be reduced to the maximum extent, and influence of the mechanism on the water navigational speed of the whole vehicle is reduced as much as possible.

    本发明提出了一种可升降带驱动履带行走机构,在陆上松软路况下,通过多级伸缩油缸的外伸依次实现多级伸缩臂及履带行走单元的外伸直至履带接触地面,该使用工况下,履带行走单元用于分担整车载荷,增大了整车车轮和履带的接地面积,降低了整车的接地比压,可改善整车在松软路况下的通过性;在水上工况下,为了降低可升降带驱动履带行走机构带来的水上阻力,可以通过控制多级伸缩油缸的收缩,从而将多级伸缩臂及履带行走单元完全收缩到车体内部,可以最大限度降低该机构的水上阻力问题,尽可能降低该机构对整车的水上航速影响。
