The invention discloses a crawler auxiliary walking system which comprises a crawler walking mechanism and a lifting mechanism enabling the crawler walking mechanism to move in the vertical directionand pitch in the advancing direction. An inducer is arranged at the grounding position in the advancing direction of a crawler so that the crawler walking mechanism can form a regular trapezoidal structure with the narrow upper portion and the wide lower portion. The crawler grounding wire length and the grounding area are increased; the occupied space of a vehicle body chassis during crawler lifting is reduced; the ground gripping and traction of the crawler on the soft ground are improved; the crawler walking mechanism is retracted and released in the longitudinal direction through the lifting mechanism, the rotation of the crawler walking mechanism around a swing arm connecting point is actively controlled through a double-hydro-pneumatic-spring structure, the pitching freedom degree ofthe crawler walking mechanism in the advancing direction is increased, and the passing capacity of the crawler auxiliary system on a muddy road surface is improved. And by adopting the second-stage oil pipe with short stroke and small damping, the function similar to spring damping is achieved, and the movement stability of the vehicle crawler chassis is improved.
本发明公开一种履带辅助行走系统,包括履带行走机构,以及使所述履带行走机构在竖直方向移动和沿行进方向俯仰的提升机构。通过将诱导轮布置在履带前行方向接地处使所述履带行走机构形成上窄下宽的正梯形结构,增加履带接地线长度和接地面积,减小履带提升时车体底盘空间占用,提高了履带在松软地面处抓地和牵引,通过提升机构,使履带行走机构在纵向收放,通过双油气弹簧结构,主动控制履带行走机构绕摆臂连接点的旋转,增加了履带行走机构沿前行方向的俯仰自由度,提高了履带辅助系统在泥泞路面通过能力。通过采用行程短、阻尼小的二级油管,起到了类似弹簧减震的功能,提升了车辆履带底盘的运动平稳性。
