Hybrid power box of power system of hybrid power motor train unit

The invention discloses a hybrid power box of a power system of a hybrid power motor train unit. The hybrid power box is composed of a box body, a differential planetary gear set, an external meshing gear set, a clutch, a lubricating system and an electric control system. The hybrid box is connected with a diesel engine, a motor (generator/motor) and a gearbox, so that the diesel engine and the motor drive the motor train unit independently or in a hybrid mode, the diesel engine charges the power battery through the motor, and the motor train unit brakes to charge the power battery through the gearbox and the motor. The purposes of high efficiency, energy conservation, greenness, low carbon and environmental protection of the hybrid power motor train unit are achieved. 本发明公开了一种混合动力动车组动力系统混动箱，由箱体、差动行星齿轮组、外啮合齿轮组、离合器、润滑系统和电控系统组成。所述混动箱连接柴油机、电机(发电机/电动机)和变速箱，实现柴油机和电机单独或混合驱动动车组，同时满足柴油机通过电机为动力电池充电，以及动车组制动通过变速箱和电机为动力电池充电。实现混合动力动车组高效、节能、绿色、低碳、环保的目标。
