摘　　要：针对目前液力机械式装载机在循环作业下存在发动机能量利用率低,刹车频率高,造成能量损失严重以及制动系统零件寿命低等问题,提出了一种基于单排双行星轮行星机构传动并可进行制动能量回收与再利用的节能结构方案。以某型号轮式装载机为研究基础,主要对装载机铲掘及制动时的节能潜力进行分析计算,并利用Simulation X软件建立装载机传动系的模型并进行仿真,研究在这些过程中发动机盈余能量及制动能量的回收情况。最后得到了装载机在相应工作状态时的能量回收效率,验证了方案的有效性。In view of that the hydraulic mechanical loader existing that engine has a low energy utilization rate and the brake has a high frequency under the cyclic operation,leading to some problems that energy loss is severe and the parts＇ life of brake system reduces.Then a project is put forward that a single row dual planetary wheel gear transmission mechanism can recover and release the braking inertia energy.Considering a loader as the research object, it mainly analyzes and calculates the energy-saving potential of the process of the loader shovel dug and the braking,then it establishes the vehicle model and makes the simulation through the SimulationX software ,aiming at studying the situation of the surplus power of engine and braking energy recycling.Last it gets the energy recovery efficiency when the loader under the corresponding working status and verifies the feasibility of this solution.
