The invention provides a gearbox double-intermediate-shaft driving system and operation machinery, and the gearbox double-intermediate-shaft driving system comprises an engine, a clutch, a gearbox, a coupler I, a coupler II, a main drive transmission shaft, a driving shaft, a hydraulic oil pump and a motor; the engine is connected with the gearbox through the clutch, and power of the engine is conveyed into the gearbox. The gearbox is connected with the driving shaft through a main driving transmission shaft and provides power for the driving shaft; the gearbox is provided with double intermediate shafts, the coupler I and the coupler II are respectively connected with the double intermediate shafts of the gearbox, and the couplers can be separated or combined and are used for conveying power; the first coupler is connected with a motor through a transmission shaft and transmits power of the motor to the gearbox. The coupler II is connected with a hydraulic oil pump through a transmission shaft and provides power for the hydraulic oil pump; according to the gearbox, engine power and/or motor power can be output through the second coupler and/or the gearbox output shaft, a hybrid power system of the crane is simplified, and the system cost is reduced. The electric energy does not need secondary conversion, and the efficiency loss is small.

    本发明提供一种变速箱双中间轴驱动系统及作业机械,系统,包括:发动机、离合器、变速箱、耦合器一、耦合器二、主驱传动轴、驱动轴、液压油泵和电机;发动机通过离合器连接变速箱,将发动机动力输送至变速箱中;变速箱通过主驱传动轴连接驱动轴,为驱动轴提供动力;变速箱设有双中间轴,耦合器一和耦合器二分别与变速箱的双中间轴连接,耦合器可以分离或结合,用于输送动力;耦合器一通过传动轴连接电机,将电机动力输送至变速箱;耦合器二通过传动轴连接液压油泵,为液压油泵提供动力;本发明的变速箱能够将发动机动力和/或电机动力通过耦合器二和/或变速箱输出轴输出,简化起重机混合动力系统,降低系统成本。电能无需二次转会,效率损失小。
