当前应用于装载机的混合动力系统主要有2种,即油-电混合动力系统和油-液混合动力系统。本文推荐另一种综合了油-电混合动力系统和油-液混合动力系统优点的装载机新型混合动力系统,即三动力源混合动力系统。1.系统组成及工作原理装载机三动力源混合动力系统的组成如图1所示。发动机、蓄电池和液压蓄能器为3个动力源。发动机、发电机、电动机串联在一起,蓄电池和发电机向电动机提供动力,由电动机驱动液力变矩
There are two main hybrid power systems currently used in loaders, that is, oil-electric hybrid systems and oil-liquid hybrid systems. This article suggests another new hybrid system, a three-power hybrid system, that combines the advantages of an oil-electric hybrid system with an oil-hydraulic hybrid system. 1. System composition and working principle Loader three power source hybrid power system shown in Figure 1. Engine, battery and hydraulic accumulator are 3 power sources. Engine, generator, motor connected in series, the battery and generator to provide power to the motor, driven by the motor hydraulic torque
