摘　　要：为研究液力变矩器闭锁技术对装载机动力性和燃油经济性的影响,对某型带闭锁离合器装载机的动力性和燃油经济性进行了计算,并与相同结构条件下不带闭锁离合器装载机进行了比较.结果表明:装备闭锁离合器后,装载机的各挡位最大输出功率之和提高了31.7%,且各挡位最高车速升高,加速时间缩短,最高车速对应的等速百公里燃油消耗量降低,说明液力变矩器闭锁技术能显著地提高装载机在高速时的动力性、燃油经济性和作业效率.In order to study the influence of torque converter lock-up technology on loader power performance and fuel economy, the power performance and fuel economy of a certain type loader with lock-up clutch was calculated and compared with the same type loader without lock-up clutch. The results show that the accumulation of maximum output power of all gears of loader increased by 31.7% after equipping lock-up clutch, the maximum speeds of different gears are increased and the corresponding kinetic 100 km fuel consumptions are decreased. It illustrates that the torque converter lock-up technology can remarkably promote the power performance at high speed, the fuel economy and the working efficiency of loader.
