The application of lock-up clutch slip control balances the fuel economy and drivability, and greatly improves the performance of hydraulic automatic transmission. The structure of the lock-up clutch and the friction material of lock-up clutch lining are discussed, a detailed research on varying characteristic due to engaging time during the lock-up clutch engagement is developed, too. By applying the slip control, lower fuel consumption is achieved. 相似文献

针对现有烟苗剪叶机操作复杂、成本高、效率低、自动化水平低等不足,设计了YJY–ZD桥式烟苗剪叶机控制系统。该系统由执行元件、信息采集单元、信息处理单元和控制电路等组成,可实现烟苗剪叶机一键启动,自动完成往复机构横向往复运动与整机纵向行走自动交互变换,运用往复运动控制算法控制往复机构往复运动,实现往复机构换向时无冲击、残余动能回收。试验测得的剪苗机作业漏剪率为0.55%,伤苗率为0.4%,漏拾率为0.4%,平均工作效率可达692 m2/h。 相似文献
