The invention relates to the field of tractor control systems, in particular to a tractor control system based on section hydraulic stepless speed change, which comprises an engine, a power unit module, a planetary hybrid module, a mechanical speed change module, a PTO (power take-off) output module and a front axle and rear axle module, the power unit module is connected with the planetary hybrid module, the planetary hybrid module is connected with the mechanical speed change module, and the problems that although the number of gears of power gear shifting is reduced, the design and control difficulty of coupling of a high-pressure and efficient hydraulic transmission system and a planetary mechanism is large, and domestic technologies are lacked in an existing liquid-mixing stepless speed change system are solved.
本发明涉及涉及拖拉机控制系统领域,具体是一种基于区段液压无级变速的拖拉机控制系统,包括发动机、动力单元模块、行星混动模块、机械变速模块、PTO输出模块和前桥后桥模块,发动机和动力单元模块相连,动力单元模块和行星混动模块相连,行星混动模块和机械变速模块相连,解决了现阶段液混无级变速系统,虽然降低了动力换挡的档位数,但高压、高效的液压传动系统、行星机构耦合的设计和控制难度大以及国内技术缺乏的问题。
