The invention provides a gearbox for engineering machinery and a control method.The gearbox is a hybrid power gearbox and comprises a hybrid power PTO assembly, and the gearbox comprises a clutch, a motor M1, a motor M2, a planet carrier locking mechanism, a planet row assembly, the hybrid power PTO assembly, a gear shifting gear assembly and a sun gear locking mechanism; an output flywheel of the engine is connected with the clutch; the sun gear locking mechanism is used for locking the sun gear and the M1 motor; the motor M2 is directly connected with a PTO gear of the hybrid power PTO assembly, and the PTO gear is connected with the planet carrier; the planet carrier locking mechanism is used for locking the planet carrier. The hybrid power PTO assembly of the gearbox can be accurately and efficiently controlled to achieve switching of multiple modes such as pure electric power, hybrid power and direct-drive power assisting. The vehicle can also realize the output of hybrid power when the engineering machinery gets on the vehicle for operation and the PTO assembly works, so that the engineering machinery is in an optimal energy efficiency mode under all working conditions, and energy is saved to the maximum extent.

    本发明提供一种工程机械用变速箱及控制方法,该变速箱是一种混合动力变速箱,且包含了混动PTO组件,该变速箱包括离合器、M1电机、M2电机、行星架锁止机构、行星排组件、混动PTO组件、换挡齿轮组件和太阳轮锁止机构;发动机输出飞轮连接离合器,太阳轮锁止机构用于锁止太阳轮与M1电机;M2电机直连所述混动PTO组件的PTO齿轮,PTO齿轮与行星架连接;行星架锁止机构用于锁止行星架。本发明可以准确高效地控制该变速箱混动PTO组件实现纯电动、混动及直驱助力等多种模式切换。车辆在工程机械上车作业PTO组件工作时也可以实现混合动力的输出,使工程机械在所有工况下都处于最优能效的模式,达到最大限度节能。
