The invention belongs to the technical field of agricultural vehicle chassis, discloses a three-degree-of-freedom ground profiling chassis, and particularly relates to the technical field of ground profiling walking of non-road operation vehicles. According to the invention, two groups of longitudinal profiling mechanisms are arranged in bilateral symmetry about the middle vertical plane of a vehicle body according to a given rear wheel distance, and a group of transverse profiling mechanisms are arranged in front according to a given vehicle axle distance; the profiling mechanisms share the same vehicle body, steering is realized by double front wheels, and driving is conducted by four rear wheels, so the three-degree-of-freedom ground profiling chassis is formed; and the two longitudinal profiling mechanisms independently conduct longitudinal profiling on a ground, the transverse profiling mechanism conducts profiling on a transverse fluctuation ground, the vehicle chassis has the three-degree-of-freedom ground profiling performance, vehicle body stability performance is achieved under the condition of adapting to a complex ground, and profiling walking and operation on the non-road ground in hills and slopes are achieved.

    本发明属于农用车辆底盘技术领域,公开了一种三自由度地面仿形底盘,特别涉及非道路作业车辆地面仿形行走技术范畴;两组纵向仿形机构依据给定的后轮轮距以车身中垂面左右对称布置,一组横向仿形机构依据给定的车辆底盘轴距前置,共用同一车身,双前轮转向,四个后轮驱动,形成三自由度地面仿形底盘;两组纵向仿形机构独立对地面纵向仿形,横向仿形机构对横向波动地面仿形,车辆底盘具备三自由度地面仿形性能,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。
