摘要

为满足拖拉机复杂多变的作业工况，设计了一种多模式机液复合传动装置。该装置综合了纯液压、分速汇矩、分矩汇速等传动模式的优点，对其调速特性、转矩特性、功率分流特性和效率进行理论分析，结果表明，所设计的多模式机液复合传动装置输出转速转矩连续，传动效率基本处于0.8以上，且除纯液压模式外，其他各模式的液压功率分流比控制在-0.2~0.3之间。建立了机液复合传动装置的仿真模型，对其进行仿真分析，结果表明，该装置调速特性良好，能够满足拖拉机复杂多变的作业工况。

Abstract

In order to meet the complex and varied working conditions of the tractor， a multi-mode hydraulic mechanical composite transmission device is designed. The device combines the advantages of pure hydraulic， speed-dividing， torque-sharing and other transmission modes. The theoretical analysis of speed regulation characteristic， torque ratio characteristics， power shunt characteristic and efficiency are carried out. The results show that the designed multi-mode hydraulic mechanical composite transmission output torque changes continuously， the transmission efficiency is above 0.8， and in addition to the pure hydraulic mode， the hydraulic power split ratio of other modes is controlled between -0.2~0.3. The simulation model of the hydraulic mechanical composite transmission device is established and simulated. The results show that the designed hydraulic mechanical composite transmission has good speed regulation characteristics and can meet the complicated and varied working conditions of the tractor.
