The invention belongs to the technical field of agricultural vehicle chassis, discloses a three-degree-of-freedom non-road ground profiling vehicle, and particularly relates to the technical field of ground profiling walking of non-road operation vehicles. Two groups of longitudinal profiling mechanisms are arranged in bilateral symmetry about the middle vertical plane of the vehicle body according to a given rear wheel distance, and one group of transverse profiling mechanisms are arranged in front according to a given vehicle axle distance, share the same vehicle body, steer by double front wheels and drive by four rear wheels, so that the three-degree-of-freedom non-road ground profiling vehicle is formed; and the two longitudinal profiling mechanisms independently conduct longitudinal profiling on the ground, and the transverse profiling mechanisms conduct profiling on the transverse fluctuation ground. The vehicle has the three-degree-of-freedom ground profiling performance, has vehicle body stability performance under the condition of adapting to the complex ground, and achieves profiling walking and operation on the non-road ground in hills and slopes.
本发明属于农用车辆底盘技术领域,公开了一种三自由度非道路地面仿形车辆,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,形成三自由度非道路地面仿形车辆;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。
