摘要
为了提高城市环卫洗扫车的多工况道路适应性,设计了一种液压机械复合传动装置,该传动装置具有纯液压、分矩汇速、分速汇矩3种作业模式,进行了调速特性、功率分流特性和效率特性的理论分析;利用AMESim软件对液压机械复合传动装置进行了仿真,仿真结果表明,不同负载转矩对输出转速影响较小;搭建试验台对液压机械复合传动装置样机进行了试验研究,得到了无级调速曲线和效率曲线。试验结果表明,所设计的洗扫车用液压机械复合传动装置具有传动平稳和效率高等优点,可以较好地满足城市环卫洗扫车在多工况作业条件下对多种模式的需求。
In order to improve the road adaptability of urban sanitation sweeping vehicle,a hydraulic mechanical compound transmission device is designed. The transmission device has three working modes of pure hydraulic pressure,torque splitting speed and speed splitting moment. The theoretical analysis of speed regulation characteristic,power shunt characteristic and efficiency characteristic is carried out,the simulation of hydraulic mechanical compound transmission device is carried out by using AMESim software. The simulation results show that different load torque has little effect on output speed. The experimental study on the prototype of hydraulic mechanical compound transmission device is carried out through building test bench and the stepless speed regulation curve and efficiency curve are obtained. The test results show that the designed hydraulic mechanical compound transmission device for the sweeping vehicle has the advantages of stable transmission and high efficiency,and can better meet the needs of the urban sanitation sweeping vehicle under various working modes.
