摘要：

针对液压传动模式和机械传动模式各自的优缺点，结合功率分、汇流机构的特点，进行了构型分析，并提出5种典型的机液复合传动方案。根据机构运动学介绍了各传动方案的结构，结合各传动方案相应的调速特性曲线，分析了不同工作模式的特点。以其中一个具有典型的传动装置为研究对象，建立Simulation X仿真模型，设置离合器的接合顺序，分析了其在不同挡位下液压系统、汇流机构、输出轴的速度变化曲线。结果表明：该变速传动装置实际调速曲线与理论调速曲线基本一致，能在较大范围内实现良好的无级调速功能，相关研究成果可为机液复合传动的实际工程运用提供理论参考。

Abstract:

According to the advantages and disadvantages of hydrostatic transmission mode and mechanical transmission mode， and the characteristics of power split mechanism and power confluence mechanism， the configuration analysis was carried out， and 5 typical hydro-mechanical composite transmission schemes was put forward. The structures of each transmission scheme were introduced according to mechanism kinematics， and the characteristics of different working modes were analyzed by combined with speed regulation characteristic curves of each transmission. Taking a typical transmission device as the research object， the simulation model based on Simulation X was built， the engaging sequence of clutches was set up， the speed changing curves of hydraulic system， confluence mechanism and output shaft in different gears were analyzed. The results show that， the actual speed regulation curves of variable speed transmission device are consistent with the theoretical speed regulation curves basically， a good continuous speed regulation function in a large range is realized， and the related research results of hydro-mechanical composite transmission can provide theoretical reference for the practical engineering application.

Key words: vehicle engineering, hydro-mechanical composite transmission, high efficiency stepless speed regulation, transmission schemes, speed regulation characteristics, Simulation X
