如果通过降低发动机额定转速来降低油耗,就必须有与其相匹配的低转速、大能容的液力变矩器,否则低转速发动机的优异性能必然发挥不出来。传动系统是工程机械的核心组成部分之一,其性能的优劣直接决定着整机的动力性能、作业效率、作业经济性和行驶性能的高低。工程机械传动系统目前国内工程机械的传动系统主要分为4类,分别为机械传动、液力传动、静液压传动和电传动。机械传动系统以机械式变速器为主,由多组不同的齿轮副组成,通过拨叉换挡,多用于1.5t以下装载机、160HP(118kW)以下推土机等小型工程机
If you reduce fuel consumption by reducing the rated engine speed, you must have its matching low-speed, high-capacity torque converter, otherwise the performance of low-speed engine will inevitably not come out. Transmission system is one of the core components of construction machinery, the performance of the merits of the direct decision of the machine’s dynamic performance, operating efficiency, operating efficiency and driving performance level. Transmission system of construction machinery At present, the transmission system of domestic construction machinery is mainly divided into four categories, namely mechanical transmission, hydraulic transmission, hydrostatic transmission and electric transmission. Mechanical transmission system mainly mechanical transmission, composed of a plurality of different gear pairs, by shift fork shift, and more for less than 1.5t loader, 160HP (118kW) following bulldozers and other small engineering machine
