工程机械一般通过柴油机—取力器—液压泵—液压马达(或液压缸)—减速器—执行元件进行功率传输,其中可调控功率的部件为柴油机、液压泵和液压马达。工程机械在作业过程中负载变化很大,如果其功率传输系统匹配不合理,不仅会造成系统发热、能源浪费和环境污染,还会影响整机性能、作业效率和使用寿命。功率传输优化匹配,就
Construction machinery is generally through the diesel - power take off - hydraulic pump - hydraulic motor (or hydraulic cylinder) - reducer - the implementation of components for power transmission, which can regulate the power of the components for the diesel engine, hydraulic pumps and hydraulic motors. The workload of construction machinery varies greatly during the operation. If the matching of power transmission system is unreasonable, it will not only cause system heat, energy waste and environmental pollution, but also affect overall performance, work efficiency and service life. Power transmission to optimize the match
