【摘要】 针对工程机械的液力变矩器使用效率较低的问题,提出了ZL50装载机基于变矩器效率的液力传动变速箱自动换档策略模式,它能够根据各种工况判断变矩器的工作状态,然后根据负载情况自动切换到恰当的档位,以保证变矩器工作在高效区,从而提高液力传动变速箱的工作效率;实现档位的自动变换,减轻驾驶员的劳动强度,提高作业效率.更多还原

【Abstract】 In order to improve the efficiency of the hydraulic torque converter of constructions vehicle, new shift schedule and auto-controlling strategy for ZL50 wheel loader by efficiency of hydraulic torque converter was proposed, which can judge the working condition of hydraulic torque converter based on the load, then determined automatic shift to the right position so as to assure the hydraulic torque converter to work in the region of high efficiency and improve the working efficiency.更多还原
