The invention belongs to the technical field of agricultural machinery, discloses an all-terrain profiling leveling chassis for hills and mountains, and particularly relates to a self-adaptive variable profiling suspension system and a three-degree-of-freedom profiling leveling chassis. The chassis is composed of a series-connection transverse swing type suspension system fixed to the front end of a main frame and two sets of self-adaption variable profiling suspension systems symmetrically distributed at the rear end of the main frame, and the upper portion of a Y-shaped cantilever is rotationally connected with a U-shaped fixing base and a vibration isolation mechanism to form a variable profiling cantilever unit. The two variable profiling cantilever units are connected with the hydraulic oil cylinder in a sliding mode to jointly form the self-adaptive variable profiling suspension system, and the series-connection transverse swing type suspension system comprises a transverse swing mechanism and a damping mechanism. In addition, chassis vehicle body posture adjustment can be achieved through active deformation of the self-adaptive variable profiling suspension system, the vehicle body stability performance is achieved under the condition of adapting to complex ground, and profiling walking and operation on non-road ground in hills and slopes are achieved.

    本发明属于农业机械技术领域,公开了一种丘陵山地全地形仿形调平底盘,特别涉及一种自适应变仿形悬架系统和三自由度仿形调平底盘;底盘由固定在主车架前端的串联横摆式悬架系统和对称分布在主车架后端的两组自适应变仿形悬架系统构成,Y形悬臂上部分别与U形固定座、隔振机构转动连接构成变仿形悬臂单元,两变仿形悬臂单元与液压油缸滑动连接共同组成自适应变仿形悬架系统,串联横摆式悬架系统包括横摆机构和减震机构,本发明底盘不仅能在崎岖不平地面上横向和纵向三自由度仿形,而且能通过自适应变仿形悬架系统主动变形实现底盘车体姿态调整,在适应复杂地面条件下具备车身稳定性能,实现丘陵、坡地非道路地面仿形行走、作业。
